Crockpot Vegetarian Black Bean and Tomatillo Soup with Lime and Cilantro
A hands-off black bean soup brightened with tomatillos, lime, cilantro, tomatoes, brown rice, and warm spices.

Ingredients
- 1 T olive oil
- 1 onion, finely chopped
- 8 tomatillos, chopped in 1/4 inch pieces
- 1 T finely minced garlic
- 1 T dried cilantro
- 2 tsp. dried Mexican Oregano
- 2 tsp. ground cumin
- 2 cans black beans, rinsed well
- 2 cans diced tomatoes with juice
- 4 cups vegetable broth
- 1 cup water
- 1/2 cup uncooked brown rice
- 1/2 cup fresh squeezed lime juice
- 1 cup chopped fresh cilantro, plus more for garnish if desired
Directions
- Cut the onions and tomatillos so the pieces are roughly 1/4 inch. Warm the olive oil in a large frying pan, add the onions and tomatillos, and cook them for about 5 minutes. Stir in the garlic, dried cilantro, Mexican Oregano, and cumin, then keep sautéing for 1-2 minutes more.
- While those vegetables are cooking, pour the beans into a colander set in the sink and rinse them until the foamy bubbles are gone.
- Transfer the tomatillo and onion mixture to a large 4-5 quart crockpot. A 5 1/2 quart crock pot also works, and it will not be completely full.
- Add the beans, tomatoes with their juice, vegetable broth, water, and brown rice.
- Cook on high for 4 hours, or use low for 8 hours instead. Since slow cookers are not all the same, check yours and adjust the cooking time depending on how hot it runs.
- After 4 hours, or after 8 hours if you cooked it on low, set the crockpot to low and let it go for 15 minutes so the temperature drops a bit. Stir in the fresh lime juice and cilantro, then cook on low for 10 minutes.
- Serve hot, with more chopped cilantro on top if you like.
- For a stovetop version, follow the same prep, but put everything into a medium sized soup pot and add 1 cup more water. Keep it at a very low simmer for about 1 hour, then lower the heat for 5 minutes. Add the lime juice and cilantro and simmer for 5 minutes more.
- Serve it hot, with extra chopped cilantro if you want it.
