How to Make Keto Slow Cooker Stuffed Pepper Soup

Step 1: Brown the Ground Beef

Start by browning the ground beef in a skillet over medium-high heat until it’s cooked through. This step is important because browning adds depth of flavor to the meat that enhances the overall taste of your soup. Once cooked, drain any excess grease before moving on.

Step 2: Add Vegetables to the Slow Cooker

In your slow cooker, add the chopped bell peppers, onions, minced garlic, Worcestershire sauce, Roma tomatoes, canned diced tomatoes, and season with salt and pepper to taste. Mixing these fresh ingredients creates a colorful base full of nutrients that will simmer beautifully together.

Step 3: Prepare the Broth Mixture

In a separate bowl, whisk together the beef broth and tomato paste until combined. This mixture will add richness to your soup and help meld all those wonderful flavors together as they cook.

Step 4: Combine Everything

Stir the cooked ground beef into your slow cooker along with all those beautiful veggies. Then pour the broth mixture over everything. Giving it a good stir ensures that all ingredients are well mixed and ready to infuse their flavors into each other during cooking.

Step 5: Cook on High

Cover your slow cooker and cook on high for about 4 hours. This slow cooking process allows all those tasty ingredients to mingle beautifully, creating an irresistible aroma that will fill your home!

Step 6: Add Cauliflower Rice

After about 4 hours, remove the lid and stir in the cauliflower rice. Cooking it last helps keep its texture nice and firm while still absorbing all those flavorful juices from the soup. Cover again and let it cook for another 30 minutes before serving.

And there you have it—a delightful bowl of Keto Slow Cooker Stuffed Pepper Soup that’s sure to become a new favorite in your household! Enjoy every spoonful!
