This recipe is not your ordinary vegan black bean soup.  

Awaken the taste of fresh home cooked black beans with roasted poblano peppers and tomatillos in a sautéed mix of aromatic vegetables, herbs, and spices to create a mouthwatering soup layered with flavor and texture.

It will take a bit longer to cook everything from scratch, but the end result will absolutely be worth it.

Stay organized to be efficient. Sauté and roast simultaneously to save time. Pressure cook the soup with an Instant Pot or other electric pressure cooker to finish preparing this hearty dinner.

I recommend the Fagor Lux pressure cooker over other pressure cookers. Read my Fagor pressure cooker review to get a comprehensive evaluation of why it is so amazing.

Vegan Black Bean Soup Ingredients

infographic of black bean soup recipe

The Star of the Show

Black turtle beans or frijoles negros in Spanish (commonly referred to just as black beans) are the main ingredient in this hearty vegan soup.  

Black beans are dense, meaty, creamy, fudgy, and earthy. The inky broth from the cooked beans make an ideal base for soup.

Grown and cultivated in the Americas, shared throughout the world, and beloved at home, black bean soup is an American classic.

Soak black beans overnight for easier digestion and reduced cooking time.

Roasted Ingredients

Poblano Peppers are mild chili peppers originating from Mexico.  When roasted they have a spicy complex flavor, perfect for adding just a little heat to the soup.

Green Tomatillos, a relative of the tomato, are tart and have their own unique taste.  They provide a sweeter flavor when roasted.

Roast the pepper and tomatillos for a deeper flavor. Skip the roasting if you are short on time.

Flavor Base

Carrots, red onion, and celery make an aromatic mirepoix.  

Mirepoix is a French cooking technique used to describe sautéing vegetables to soften them and bring out their sweet taste in a flavorful base.

Flavor Boosters

Garlic, cilantro, cumin seeds, oregano, bay leaf, and corn boost the flavor of the mirepoix.

Cooking Liquid

Vegetable or beef broth (if you aren’t vegan) cooks the black beans.

Flavor Enhancers and Balancers

Lime juice and salt balance and enhance the flavor of the soup.

3 Layers of Flavor in Black Bean Soup

Roast to Bring Out New Flavors

The first layer of flavor comes from roasted vegetables.  This step is optional, but it adds a new dimension of flavor.

An interesting scientific change happens during roasting.  High dry heat causes the Maillard reaction (or browning) and develops more flavor in the food.

  • Preheat the oven to 425° Fahrenheit.

The poblano peppers take 25 to 30 minutes to roast while the tomatillos only take 10 to 15 minutes to roast.

  • Prepare the vegetables.

Use food handlers gloves and cut the stem off the pepper.  Slice it in half vertically and remove the seeds.

Remove the husk from the tomatillos and cut them in half.  

Brush the poblano peppers and the tomatillos with a a high smoke point oil.

  • Place the poblanos in the oven first.  Turn them with tongs after 15 minutes.
  • Add the tomatillos.  Turn after 10 minutes.

Keep an eye on the vegetables and remove any that have finished cooking before the rest of the vegetables are roasted.

  • When everything is done roasting, remove the pan from the oven and cool.
  • Place the poblano peppers in a bowl covered with a kitchen towel.  As they cool, the skin loosens. Cover for about 10 minutes, or until cool to touch.
  • Use food handlers gloves to peel off the skin.
  • When the skin is removed, dice the pepper.

In a hurry? You can substitute canned diced chili for fresh roasted poblanos and skip roasting the tomatillos.


The soup base is the second layer of flavor.  Take a few minutes to make a mirepoix with aromatic vegetables – red onion, carrots, and celery.

A mirepoix is a French cooking technique where onions, carrots, and celery are slow cooked to soften and sweeten them.  

  • Dice the vegetables to equal sizes so they will cook quickly and evenly.
  • Modify a traditional mirepoix ratio by using 1 cup red onion, 1 cup carrot, and ½ cup celery.
  • Make the mirepoix in the pressure cooker pot on the sauté setting.
  • Cook the onions and carrots for 10 minutes, until they begin to soften.
  • Add the celery and sauté for another 5 minutes until it softens.
  • Add the garlic to boost the flavor, followed by the freshly ground cumin seeds, allowing the flavor to bloom as it cooks in the oil.  

Pressure Cook

When the flavor base is made and the vegetables are roasted, add the remaining vegetables, broth and beans to the pot.

Close the lid and pressure cook for 15 minutes if you are using pre-cooked black beans or black beans from a can.

Partially Blend

When the black bean soup has finished cooking, allow the pressure cooker to release pressure on its own.  This gives the beans a chance to cook a little more, resulting in a creamier bean and broth.

Use an immersion blender to partially blend the soup.  

Another option is to blend half the soup in an electric blender and then return the pureėd soup to the pot and stir to blend.

Add the lime juice and the salt.  Taste and adjust seasonings as needed.

Garnish and serve hot.

Vegan Black Bean Soup in Pressure Cooker

bowl of black bean soup

Mouthwatering vegan black bean soup made with roasted poblanos and tomatillos, corn, red onions, carrots, celery, and cilantro. 

Prep Time 20 minutes
Roasting and Sauteing Time 30 minutes
Pressure Cook Time 25 minutes
Total Time 1 hour 15 minutes


  • 1 cup dry black turtle beans (or 2 ½ cups cooked or canned black beans)
  • 2 cups vegetable or beef broth
  • 2 whole poblano peppers or 3 tablespoons of poblano peppers, roasted, peeled, and minced (can of diced green chiles can be substituted)
  • ½ cup (2 ½ ounces) tomatillos, roasted and chopped
  • 1 cup (4 ½ ounces) red onion, diced
  • 1 cup (5 ounces) carrots, peeled and diced
  • ¾ cup (2 ounces) celery, diced
  • 1 ½ teaspoons (2 cloves) garlic, minced
  • ½ cup (2 ½ ounces) corn
  • 2 ½ tablespoons grapeseed or extra virgin olive oil


  • 1 bay leaf
  • ¼ cup (¼ ounce) cilantro, chopped
  • ½ teaspoon cumin seeds, freshly ground (or cumin powder)
  • 1 teaspoon fresh or ½ teaspoon dry oregano
  • 1 teaspoon salt (plus more to taste)
  • 1 tablespoon lime juice (or to taste) - about half a lime

Suggested Toppings - 2 or 3 of your favorites

  • roasted red peppers, queso fresco, shredded Monterey jack cheese, chopped green onions, caramelized onions, tortilla strips, avocado slices, guacamole, crema or sour cream


Read the complete directions before you start. With organization you can roast and sauté simultaneously to save time.


  1. SOAK the black beans overnight in enough water to cover them 3 inches.
  2. DRAIN the beans.
  3. PRESSURE COOK BEANS. Place drained beans in an electric pressure cooker and cover with 2 inches of water. Secure the lid on the pressure cooker and cook at high pressure for 12 minutes. Release the pressure naturally.

Alternately, you can use canned beans instead of cooking the beans from scratch. Use 2 (15 oz.) cans of black beans.


  1. GATHER all the ingredients.
  2. PREHEAT oven to 400° Fahrenheit.
  3. CUT stem off the poblano peppers. Cut peppers in half and remove seeds. (Use food safety gloves to prevent juice from stinging your hands.)
  4. REMOVE the husk from the tomatillos. Cut them in half.
  5. BRUSH the peppers and tomatillos with grapeseed or extra virgin olive oil.
  6. PLACE the peppers only on a baking sheet and roast in the oven for 15 minutes.
  7. When the timer goes off, TURN the poblano pepper over to roast the other side. Add the tomatillos to the baking sheet and roast for 15 minutes.
  8. REMOVE the vegetables from the oven.
  9. COVER the poblano peppers in a bowl with a towel or plate on top of the bowl. Allow peppers to steam and cool for 10 minutes. This process loosens the skins from the peppers.
  10. PEEL the peppers using food handler gloves. Dice the peppers.

Roasting the vegetables adds an additional layer of flavor. However, to save time, you can skip this step and add the unroasted vegetables to the soup. You can also used canned green chiles in place of the poblano peppers.


  1. DICE the red onion, celery, and carrot, and mince the garlic.
  2. CHOP the cilantro and grind the cumin seeds with a mortar and pestle or a spice grinder.
  3. HEAT the electric pressure cooker on the sauté setting. When the pot is hot, add 2 tablespoons of grapeseed or extra virgin olive oil.
  4. COOK a mirepoix by sautéing the onion and carrots in the oil for 10 minutes. The sauté setting should be medium low heat.
  5. ADD the celery and sauté for another 5 to 10 minutes or until the vegetables are soft.
  6. STIR the garlic and freshly ground cumin seeds into the mirepoix. Cook for 2 minutes to let the flavor bloom.
  7. POUR the broth, beans, and the remaining ingredients, except for the lime juice into the pressure cooker.
  8. PRESSURE on high for 15 minutes.
  9. RELEASE pressure naturally.
  10. PARTIALLY BLEND the soup with an immersion blender.
  11. STIR in the lime juice.
  12. TASTE and ADJUST seasonings. I usually add another teaspoon of salt and sometimes more lime juice.
  13. SERVE hot with 2 or 3 of the suggested toppings. Avocado, caramelized onions, and queso fresco are especially good choices.


If you do not have an electric pressure cooker, you can cook the soup in a stock pot on the stove top.

  1. FOLLOW steps 1 and 2 above.
  2. HEAT a stock pot, add the oil, and follow steps 4, 5, and 6.
  3. POUR the broth, beans, and the remaining ingredients, except for the lime juice into the stock pot and cover with the lid. Bring the soup to a boil.
  4. REDUCE HEAT TO LOW and cook at a simmer for 20 to 25 minutes, or until the vegetables are soft.
  5. FOLLOW steps 10-13.
