Instructions

Sauté the Ground Beef and Onions:
Place a large skillet over medium heat and add the ground beef along with diced onions. Cook for about five to seven minutes until the beef is fully browned and onions are translucent. Drain excess fat to keep the soup from becoming greasy. Transfer this mixture to a six-quart slow cooker.
Combine the Remaining Ingredients:
Add the chopped red and green bell peppers to the slow cooker followed by tomato sauce, Rotel tomatoes with juice, Worcestershire sauce, brown sugar, beef broth, water, black pepper, salt, basil, oregano, parsley, mustard powder, and paprika. Stir all ingredients thoroughly to ensure flavors meld before cooking.
Slow Cook Until Peppers Are Tender:
Cover the slow cooker and cook on high for two and a half to three and a half hours or on low for six to eight hours. The bell peppers should become soft but not mushy, infusing the soup with their fresh taste and color.
Incorporate the Cooked Rice:
About fifteen minutes before the end of the cooking time, add the fully cooked white rice to the slow cooker. Stir well so the rice soaks up the savory broth. Replace the lid and continue cooking for another fifteen minutes to heat the rice through without losing texture.

My favorite parts are the two types of bell peppers which bring a nice blend of sweetness and slight earthiness to the soup. There is a special memory tied to this meal when I served it at a family gathering and everyone went back for seconds. It really feels like a warm hug on a plate.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to four days. Reheat gently on the stovetop or in the microwave to maintain texture and flavor. This soup also freezes well in portioned freezer bags or containers for up to three months. Thaw overnight in the fridge for best results and warm thoroughly before serving.

Ingredient Substitutions

Ground turkey or ground chicken works well for a lighter protein alternative though it may need additional seasoning. You can swap the Rotel tomatoes for diced tomatoes with a pinch of chili flakes for custom heat level. Use quinoa or cauliflower rice instead of white rice for a gluten-free or low-carb version.

Serving Suggestions

Serve with crusty bread or garlic breadsticks for dipping. A side green salad with a light vinaigrette provides fresh contrast to the rich soup. Top finished bowls with shredded cheddar or a sprinkle of Parmesan cheese for extra indulgence.
