A colorful blend of bell peppers and fragrant ground cumin give this black bean soup a Mexican flair. It's an easy, one-pot recipe that cooks in about 30 minutes.
Sauté the vegetables. Heat 2 tablespoons canola oil in a large heavy pot over medium heat. Add 1 chopped yellow onion, 1 chopped green bell pepper, 1 chopped red bell pepper, and cook for 4-5 minutes until soft and translucent.
Add the aromatics. Add 4 pressed garlic cloves, 1 ½ teaspoons cumin, and 1 ½ teaspoons oregano, stir well to coat the vegetables, and cook for 1-2 more minutes until the garlic is fragrant.
Stir in the broth and beans. Add 32 ounces of chicken broth and bring to a simmer. Add 4 15-ounce cans black beans with their liquid, 1 ½ teaspoons sugar, 1 tablespoon cider vinegar, 1 teaspoon kosher salt, and 1 teaspoon black pepper. Simmer for 20-25 minutes, stirring occasionally.
Blend if you like a thicker soup. Ladle 1 to 1 ½ cups of the soup into a blender or use an immersion blender to purée the mixture so it’s still somewhat chunky but mostly smooth. Stir back into the soup. Garnish with desired toppings and serve.
