The slow cooking process locks in all the flavors, creating a rich and comforting texture that’s simply irresistible.
Step-by-Step Instructions
- Brown the Ground Beef: Heat the olive oil in a large skillet or Dutch oven over medium-high heat. Add the ground beef and cook, breaking it up with a spoon, until browned. Drain off any excess grease and set aside.
- Sauté the Aromatics: In the same skillet (or directly into your slow cooker insert if it’s stovetop safe), add the chopped yellow onion and bell peppers. Cook over medium heat for about 5-7 minutes, until softened. Add the minced garlic and cook for another minute until fragrant.
- Combine Ingredients in Slow Cooker: Transfer the browned ground beef, sautéed onions, bell peppers, and garlic to your slow cooker insert.
- Add Tomatoes and Beans: Pour in the crushed tomatoes and the undrained diced tomatoes. Add the drained and rinsed kidney beans, black beans, and pinto beans.
- Incorporate Chilies and Spices: Stir in the can of chopped green chilies (undrained for extra moisture and flavor). Add the chili powder, cumin, smoked paprika, dried oregano, and cayenne pepper.
- Season and Add the Secret Ingredient: Season with salt and black pepper to taste. Pour in the secret ingredient: the strong brewed coffee. The coffee adds a subtle depth of flavor and richness that chocolate chips or cocoa powder sometimes provide, but without any coffee taste.
- Stir and Cook: Stir all the ingredients thoroughly to combine.
- Slow Cook: Cover the slow cooker and cook on low for 6-8 hours, or on high for 3-4 hours, until the chili is heated through and the flavors have melded beautifully.
- Adjust Seasoning: Before serving, taste the chili and adjust salt, pepper, or cayenne pepper as needed.
