Step‑by‑Step Instructions for Slow Cooker High-Protein Beef Chili
Step 1: Brown the Ground Beef
Begin by heating a large skillet over medium-high heat. Add the ground beef and cook until browned, about 5-7 minutes, breaking it apart with a spatula. This step enhances the flavor of your Slow Cooker High-Protein Beef Chili, so don’t skip it! Once cooked, drain excess fat and set aside.
Step 2: Prepare the Vegetables
Chop the onion, bell peppers, carrots, and garlic finely. In the same skillet, sauté the onion and garlic for 2-3 minutes until the onion is translucent and fragrant. Add the bell peppers and carrots, cooking for another 3-4 minutes. This not only builds flavor but also ensures your vegetables are tender in the final chili.
Step 3: Layer the Ingredients
Transfer the browned beef and sautéed vegetables to your slow cooker. Add the diced tomatoes, tomato sauce, and beans, stirring gently to combine. This will create a hearty base for your Slow Cooker High-Protein Beef Chili. Make sure all ingredients are evenly distributed across the bottom before proceeding to the next step.
Step 4: Add Seasoning
Sprinkle in the chili powder, cumin, oregano, salt, and pepper. Mix everything together well, ensuring that the spices are evenly distributed throughout the chili mixture. The aroma will start to fill your kitchen, promising a delicious meal ahead. Adjust the seasoning based on your preferred level of spice!
Step 5: Set the Slow Cooker
Secure the lid on your slow cooker, and set it to LOW for 6-8 hours or HIGH for 3-4 hours. The longer cooking time allows the flavors to meld beautifully, creating a rich base. Resist the urge to lift the lid during cooking, as this adds 15-20 minutes to the overall time.
Step 6: Finish Cooking
When the cooking time is up, check the chili for doneness. If using ground beef, it should be tender and flavorful. If you prefer a thicker chili, let it sit uncovered for an additional 15-30 minutes on HIGH. Stir gently to combine any separated ingredients before serving.
Step 7: Serve and Garnish
Ladle the Slow Cooker High-Protein Beef Chili into bowls and top with Greek yogurt or sour cream for added creaminess. Garnish with finely chopped cilantro and a sprinkle of shredded cheese, if desired. This final touch not only enhances flavor but also adds a delightful visual appeal to your comforting dish.
