Italian White Bean Soup with Fresh Rosemary and Basil

Italian white bean soup

Soup is hearty, nourishing, and satisfying

Hearty and nourishing, Italian white bean soup is what you need to sustain you through a long work day, when taking care of children or nursing a baby, to refuel after a workout, or frankly anytime you want a satisfying meal. This plant-based soup is chock full of vitamins and minerals that are easy for your body to assimilate because all of the vegetables, beans, and sea salt are cooked together in a broth. Bean soups generally reheat well, so make a double or triple batch so that you can store some in the freezer and thaw it out for last-minute weeknight meals. I always add some fresh greens like baby spinach or kale when reheating my soup on the stove. It adds freshness and color to what would otherwise be a boring leftover meal.


Homemade or canned beans?

You can sub 2 cans of white beans for the homemade beans in this recipe, but it will not be as delicious. Homemade beans are truly wonderful, more digestible (when soaked, drained, and cooked with kombu) and flavorful than canned, but you do have to plan ahead. I usually soak a big batch of beans every week or two, and cook them until soft and season with sea salt. If you use a pressure cooker, it cuts down on the cooking time. I freeze whatever I’m not going to use in the next few days in quart-sized freezer bags. When it comes time to make a soup I thaw out a bag of beans instead of having to start from scratch. More detailed instructions on how to make beans from scratch are in my posts Homemade Black Beans and Macrobiotic-style Giant Peruvian Lima Beans.


Fresh ingredients are the key to a delicious soup

Choose ingredients that are fresh and full of life. If celery or carrots have gone limp, you can perk them up by cutting a little slice off the bottom of each vegetable and stand up in a quart-sized mason jar filled halfway with water. Within 30-60 minutes your vegetables should be rehydrated and ready to use. The last few years I’ve been growing fresh herbs in pots on my back porch. You can even put a little planter in a sunny windowsill if you don’t have a yard or porch to garden in. It’s amazing how much more delicious herbs are when picked right before you use them.

Ingredients
  • Beans
  • 1 cup dried organic white beans (cannellini, navy, or giant white lima)
  • kombu, 1” square
  • spring or filtered water
  • ½ teaspoon sea salt
  • Soup
  • 1 small yellow onion or sweet onion, diced
  • pinch unrefined sea salt
  • 1 tablespoons organic extra virgin olive oil
  • 2 carrots, diced
  • 2 celery stalks, sliced in diagonals
  • 1 zucchini, sliced in quarter moons
  • 2 cloves garlic, chopped
  • 1 teaspoon fresh rosemary, minced

Instructions
Beans
  1. Sort, rinse, and soak the beans in spring or filtered water overnight. When beans are rehydrated, discard the bean soaking water.
  2. In medium pot, add beans and enough water to cover beans by about 2 inches and bring to a boil. Skim foam and add kombu. Cover, turn to low, and simmer until beans are tender. Season with sea salt and set aside. Alternatively, pressure cook white beans instead of boiling after skimming foam and adding kombu. Once beans are up to pressure with lid locked, turn to low and cook for about 15 minutes. Then turn off heat and let come down from pressure naturally before opening up pot.
Soup
  1. In medium-sized soup pot, sauté onion with a pinch of sea salt in olive oil until soft.
  2. Add carrots, celery, zucchini, garlic, and rosemary, and cook a few minutes more.
  3. Add cooked beans and water or stock. Simmer for about 10-15 minutes, until flavors are blended.
  4. Add basil and season with more sea salt, if needed.
  5. Garnish with fresh parsley or other seasonal herbs and serve warm.
Variations
  1. Garnish with pieces of pan-fried dulse instead of parsley.
  2. When reheating, add a handful of baby spinach or kale.
  3. Make a large batch and freeze half to warm up later.
  4. Use chicken stock or chicken bone broth in place of the vegetable stock.
  5. Add 1 cup cooked shredded chicken for a heartier soup.

Asian Mushroom Lettuce Wraps (V, GF, soy-free)

Asian mushroom lettuce wraps are the perfect start to an Asian-themed meal or any plant-based gathering. I brought these to a potluck last week held in honor of a friend visiting from Asheville. By the end of dinner, all that was left was one lonely lettuce leaf!

I wanted to make these lettuce wraps healthier than the restaurant variety, so added more vegetables, and left out the soy, sugar, and gluten! Instead of soy sauce or tamari I used Coco Aminos (I like the Big Tree Farms brand) which is naturally sweet and savory. If you like your filling a little sweeter, you can always add a dash of maple syrup or agave, but you probably won’t need to.

Italian Chickpea Soup with Fusilli Pasta

Over the years, this Italian Chickpea Soup has been a family favorite and has always gone over well with children visiting our home.The addition of pasta makes the soup heartier, like a minestrone, and can definitely be considered a one-pot meal.

I recently had the opportunity to teach a cooking class at my daughter’s elementary classroom where I decided to serve the soup with pasta and bread, which was a real hit! An added bonus is how economical this recipe is. We made this recipe X4, which fed about 35 people, using all organic ingredients, for under $2 per person including soup, pasta, bread, and butter.

Day 1 of our cooking class involved walking to the grocery store, selecting our groceries, and carrying our groceries back in a wagon! When we got back to the classroom, we soaked the chickpeas so they would be ready to cook the following day.

Day 2 of our cooking class involved cooking the chickpeas in the pressure cooker, and slicing, dicing, and sautéing vegetables for the soup.

The secret to making this soup delicious is to make your chickpeas from scratch. Make your chickpeas in advance, as it takes a good 8-10 hours to rehydrate the dried chickpeas (I usually do this step overnight), and some more time to cook them. I use a pressure-cooker to make my chickpeas, but they can be made in a regular pot (it just takes longer). I recommend making a big batch of chickpeas and freezing some away in quart-sized freezer bags that you can use later on to make hummus or another batch of soup. Here is my recipe for Homemade Chickpeas.

Serves: 6 servings
Ingredients
  • 1 recipe Homemade Chickpeas or 3 cups cooked chickpeas
  • 2 tablespoons extra-virgin olive oil, divided
  • 1 small onion, diced
  • 2 teaspoons fresh rosemary, minced
  • 2 stalks celery, sliced
  • 2 medium carrots, sliced into rounds or half moons
  • 2 medium zucchini, sliced into half or quarter moons

  • sea salt, to taste
  • freshly ground black pepper, to taste
Instructions
  1. Follow instructions for making Homemade Chickpeas. Set chickpeas aside. Do not drain, as the chickpea cooking liquid will be used in the soup. If using canned chickpeas you will need to drain the liquid from the can.
  2. In 3- to 5-quart soup pot, sauté onion in 1 tablespoon olive oil and a pinch of sea salt for about 10 minutes over medium or medium-low heat. Add rosemary and stir to coat onions. Add another tablespoon olive oil, celery, carrot, and another pinch sea salt and sauté about 10 minutes more. Adjust heat if necessary to prevent burning. Add zucchini and sauté a minute more.
  3. Place chickpeas and chickpea cooking liquid into soup pot and add stock and bay leaf. Bring to a boil, then turn heat to low, cover, and simmer until zucchini is soft, about 8 minutes. Add half of fresh herbs. Season with salt and pepper to taste.
  4. Serve pasta in soup bowls and pour chickpea soup over the pasta.
  5. Garnish each bowl with remaining fresh herbs and/or grated cheese (if using).
Notes:
  1. Make this recipe gluten-free by using a gluten-free variety of pasta.
  2. If using canned chickpeas, add 3 cloves minced garlic along with carrots and celery.

By noon our cooking crew was ready to serve their homemade soup, pasta, and bread to the class.

Macrobiotic Nishime Style Vegetables with Crispy Tempeh

Most of us know we should eat more vegetables. Macrobiotic niishime style vegetables are slowly steamed or braised until the cooking liquid has evaporated, leaving the vegetables sweet, flavorful, and creamy, but not overcooked or mushy. Here, we take it up a notch by adding some crispy pan-fried tempeh. Traditionally, this dish is a Japanese dish served at New Year’s or to people healing from an illness.

There is an art to making this dish– you must use the minimum amount of water so that you don’t lose nutrients or flavor into the steaming liquid, you avoid burning the bottom of the pot. Ideally, you will steam the vegetables just long enough that no liquid remains. This can be achieved with patience– you must slowly bring the pot to a boil, covered, until you see steam coming out the sides of the pot. Do not lift the lid when you see the steam, simply turn the burner down as low as it will go, and let steam for about 20 minutes before checking for doneness.

I used Flying Tempeh Bros. tempeh available at Wheatsville Coop in their freezer section.

Tempeh should be a nice golden brown on at least 2 sides before seasoning with shoyu or tamari.

crispy pan-fried tempeh

Dried lotus root is a specialty ingredient in this recipe. You can substitute another vegetable such as green cabbage, but lotus root has a delicious and unique flavor (almost like a very flavorful, less starchy potato) that you’ll want to try sometime. In Austin, you can buy this at Central Market. For an extra special touch, try pan frying the lotus root (after it has rehydrated) before putting into the pot with the other vegetables.

Another specialty ingredient used in this recipe is kombu sea vegetable. It adds flavor and minerals to the vegetables and also helps prevent the vegetables from sticking to the pot. You can find Atlantic varieties of kombu at Wheatsville Coop such as the Ironbound Island or Maine Coast Sea Vegetables brands.

Ingredients
  • 8 ounces tempeh, cubed
  • 2 teaspoon untoasted sesame oil or extra-virgin olive oil
  • shoyu or tamari, to taste
  • 2 small squares kombu
  • 1 cup kabocha, butternut, or delicata squash, cut into 1-inch chunks
  • 1 cup carrots, cut into ½-inch chunks or roll cut
  • 1 cup yellow onion, large dice
  • 1 cup daikon, cut into ½-inch rounds
  • ½ cup dried lotus root slices, rehydrated (soak in water overnight)
  • spring or filtered water
Instructions
  1. Heat cast iron skillet over medium heat and add oil. Pan fry tempeh for about 3 minutes on each side. Remove to a plate and sprinkle generously with shoyu or tamari. Set aside.
  2. Place kombu in bottom of heavy pot with lid (such as a Le Creuset round oven) and cover the bottom with about ¼-inch water. Layer vegetables on top of kombu and sprinkle evenly with a few pinches sea salt. Add pan-fried tempeh.
  3. Cover pot and place on medium heat until it comes to a boil and a good steam is generated (you will see the steam coming out of the sides of the pot). Do not open lid at this point.
  4. Lower the flame and simmer for 15 to 20 minutes or until vegetables become soft. Check for doneness by piercing a carrot or daikon chunk with a fork to see if it is tender.
  5. Season lightly with shoyu or tamari, turn off flame, and cover for a few minutes (or simmer for a few more minutes if needed).
  6. Toss pot gently with the lid on (do not stir) to distribute juices and serve.

Mmmm… Now eat your veggies!

Creamy Butternut Squash Soup with Fresh Rosemary and Basil

creamy butternut squash soup

Creamy Butternut Squash Soup… this is what talked me into becoming a macrobiotic chef! It is sweet, savory, comforting, and delicious! As a child, the only way I saw butternut squash cooked was in a baked casserole with sour cream, onions, and a corn flake topping. I didn’t like it. But when I tried this soup, I was in heaven! I have recently revised this recipe to include a long, slow caramelization of onion, carrot, and celery (mirepoix) at the beginning, which gives the soup a very sweet, complex, and delicious flavor.

By Pigup – I made the mirepoix at home and took a picture of it on my cell phone., CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=18688674

Creamy vegetable soups help stabilize blood sugar levels, so help prevent sugar cravings when eaten regularly. When using organic squash, there is no need to remove the skin. This makes it much faster to make, and adds beneficial dietary fiber. These days, finding food that is naturally sweet and nutritious is so important, to nourish the body while curbing cravings for refined sugar. I recently listened to a news story on NPR’s “Here & Now” about how the food industry engineers processed and prepared food items (including pasta sauce, yogurt, and other processed foods not thought to be “sugary”) so that they reach a person’s “bliss point.” Children are especially susceptible to getting hooked on these foods since they are naturally attracted to the sweet taste (which is needed for growth in mild, natural forms). Try making this soup for your children, and try substituting other vegetables for the butternut squash, such as carrots, broccoli, cauliflower, zucchini, or sweet potato. It makes a great kids’ lunchbox item when carried in a thermos.

The only trick with making this soup is learning how to cut the squash without cutting yourself. You need a good, sharp chef knife and a large cutting board. I suggest trimming off the stem, cutting off the “neck” of the squash, then cutting the resulting pieces (neck and bulb) in half so that you have four pieces you can put down flat on the board. From there you can remove the seeds from the bulbous part of the squash and chop the squash into small pieces.

Enjoy this soup and try some of the variations suggested at the bottom of the recipe. They are all delicious!

Recipe type: Soup
Cuisine: Macrobiotic
Serves: 4-6 servings
Ingredients
  • 1 cup yellow onion, finely diced
  • ½ cup carrot, finely diced
  • ½ cup celery, finely diced
  • 1 tablespoon extra virgin olive oil
  • pinch sea salt
  • 5 cups butternut squash, seeded and cubed
  • 1 teaspoon fresh rosemary, minced
  • 3 cups spring or filtered water or light vegetable stock
  • 5 fresh basil leaves, sliced thinly (chiffonade)
  • sea salt, to taste
  • ¼ cup organic pumpkin seeds, toasted, for garnish
Instructions
  1. In a 4-quart soup pot, sauté onion and pinch of sea salt in olive oil over medium-low heat until translucent.
  2. Add carrot and celery and another pinch of sea salt. Sauté another 15 minutes, until vegetables start to caramelize.
  3. Add butternut squash and rosemary and coat with onion mixture. Add enough water or vegetable stock to barely cover the squash (about 3 cups), cover, and bring to a boil. Turn heat to low and cover. Simmer until squash is soft, about 10-15 minutes.
  4. Puree with blender or immersion blender. If soup is too thick, add a little more water or vegetable stock. Season to taste with sea salt.
  5. Simmer on low heat for another 5 minutes.
  6. Serve in bowls and garnish with toasted pumpkin seeds.
Note
  1. If using vegetable stock, try to find one without tomatoes (such as Imagine brand Vegetarian No-Chicken Broth) or make your own, to avoid overpowering the flavor of the squash.
Variations
  1. Substitute kabocha squash for butternut squash. The color will be darker but it is very delicious.
  2. Substitute carrots, broccoli, cauliflower, zucchini, sweet potato, or sweet corn for the butternut squash.
  3. Use herbs and spices of choice instead of rosemary, such as thyme, basil, or fresh ginger.
  4. Roast butternut squash tossed in olive oil and sea salt in 425 degree F oven until soft. Add to sautéed onions and proceed with recipe.

Bon appétit!

 

Cecilia’s Pozole Verde

pozole verde

Mmm… Posole soup! Cecilia Torres, my friend and former student, sent me this recipe for Pozole Verde after returning home to León, Mexico this winter. Upon finishing her culinary studies at The Natural Epicurean, she got right back to work cooking amazing things in her kitchen, including the creation of authentic Mexican versions of recipes we did in class. They are all incredibly beautiful! Be sure to check out Cecilia’s food pictures on Instagram.

Pozole or posole refers to the large type of corn as well as the soup made with it. Perhaps you are familiar with pork or chicken-based pozole soups that are stewed for a whole day or two. This version is much fresher, greener, and gets its flavor from the poszole corn and the delicious verde sauce made with roasted poblanos, tomatillos, and lettuce. Flavorful ingredients are made fresh to top the soup with, making it fun for kids of all ages to customize their own bowls.

Here is the the version I made with Nelson at home yesterday. We added zucchini and serrano pepper (as we forgot to buy the poblanos) as well as a little shredded chicken we had leftover from making a chicken stock. It was still amazing! Another thing we tried was to sauté the cooked pozole corn in olive oil with ground Ancho chile and salt. It had a beautiful color and amazing flavor when added to the soup as a garnish.

Here is a photo of Cecilia and I at the Vegan Thanksgiving class we taught together at the Natural Epicurean in November 2016. I miss her so much!

Roasted Carrot and Fennel Soup

Spring is the perfect time in Central Texas to get farm fresh fennel and carrots. I couldn’t resist making this simple soup today for a client when I saw the big bulbs of fennel at the market. The flavors are much sweeter and complex due to the roasting of the carrots and fennel prior to adding them to the soup. Reserve fennel stems and core for juicing, if you wish.

Recipe type: Soup
Cuisine: Macrobiotic
Serves: 6 servings
Ingredients
  • 1 pound organic carrots
  • 1 large organic fennel bulb
  • 3 tablespoons organic extra virgin olive oil, divided
  • 1 cup diced organic yellow onion
  • 4-6 cups light vegetable stock (no-tomato)
  • sea salt, to taste
  • 1 tablespoon chopped fennel fronds, for garnish
Instructions
  1. Preheat oven to 400 degrees F.
  2. Wash carrots and trim off the ends. Slice carrots into ½-inch diagonals. Place in a large glass baking dish or roasting pan.
  3. Wash fennel and trim off stems and fronds, reserving a few fronds for garnishing. Slice fennel bulb into quarters, cut out the core, and discard the core. Slice remaining fennel bulb into ½-inch slices and add to carrots in baking dish.
  4. Toss carrots and fennel with 2 tablespoons olive oil and sprinkle generously with sea salt. Cover baking dish with foil and roast for about 30 minutes, or until vegetables are tender and are beginning to brown slightly.
  5. Meanwhile, saute onion, a pinch of sea salt, and remaining tablespoon of olive oil in large soup pot over medium heat until the onion is soft and translucent.
  6. Add roasted carrots and fennel to soup pot and saute a minute more.
  7. Add 4 cups vegetable stock, or enough stock to just cover the vegetables. Simmer until flavors blend, about 10 minutes.
  8. Blend the soup in the pot with an immersion blender until smooth. Add more stock as needed to achieve the consistency you like. It is important not to add too much liquid initially as it will be difficult to achieve a smooth texture.
  9. Season with sea salt and simmer gently for 10 minutes more.
  10. Serve warm or chilled in individual bowls with a few fennel fronds for garnish.
