This crockpot black bean soup can be served as is or run through the blender for a creamy version. You can adjust the spice to cool it down.
For a richer, more complex flavor profile, consider sautéing half a diced onion and 2 cloves of minced garlic in a tablespoon of oil for 5 minutes before adding them to the slow cooker. This builds an aromatic base. Always ensure beans are properly soaked and rinsed to aid digestion and reduce cooking time. The spice level is quite robust; for less heat, reduce cayenne and hot pepper sauce, or remove seeds from jalapeños. A squeeze of fresh lime juice and a handful of chopped cilantro or a dollop of Greek yogurt as a garnish will brighten the flavors significantly and add a professional touch to the presentation.
