When the autumn chill rolls in and you crave the hearty, satisfying comfort of classic stuffed peppers without the fussy parboiling and stuffing, this Slow-Cooker Stuffed Bell Pepper Soup with Ground Beef and Rice is the ultimate solution. Packed with savory browned ground beef, sweet diced bell peppers, fire-roasted tomatoes, and tender fluffy rice swimming in a rich, slow-simmered herb tomato broth, it delivers all the nostalgic flavors of home cooking in an effortless, one-pot crockpot masterpiece that warms you from the inside out.
Traditional stuffed peppers are undeniably delicious, but baking whole hollowed peppers often leaves them unevenly cooked or underseasoned. Transforming the dish into a slow-cooked soup allows every spoonful to soak up deep savory flavor. As the bell peppers gently tenderize in the fire-roasted tomato broth over 6 hours, their natural sweetness balances the earthy beef and aromatic herbs, creating an irresistibly thick, spoon-coating comfort soup that tastes even better the next day.

Key Ingredients & Smart Swaps
- Lean Halal Ground Beef: 85/15 or 90/10 lean beef provides rich meaty depth without leaving excess grease in the soup. You can also swap in ground turkey or ground chicken for an even lighter lunch!
- Trio of Fresh Bell Peppers: A combination of green, red, and yellow bell peppers provides both the traditional tangy bite and sweet autumn vibrancy. Chop into uniform 1/2-inch pieces so they hold their texture during slow cooking.
- Fire-Roasted Diced Tomatoes: Fire-roasted canned tomatoes infuse a subtle smoky char into the tomato broth that elevates the entire soup.
- Rich Beef Broth & Tomato Paste: The rich beef broth combined with concentrated tomato paste builds an umami-packed foundation that makes the soup taste like it simmered all day.
- Cooked Long-Grain Rice: Long-grain white rice or jasmine rice holds up best. Brown rice or cauliflower rice also make fantastic fiber-rich or low-carb alternatives!
Step-by-Step Cooking Walkthrough
1. Sear the Beef & Aromatics: Brown ground beef and diced onion in a hot skillet for 6 to 8 minutes. Add minced garlic for 1 minute, drain any fat, and transfer to your slow cooker.
2. Combine Soup Ingredients: Add chopped bell peppers, fire-roasted tomatoes, tomato sauce, broth, tomato paste, Worcestershire, and seasonings. Stir until smoothly combined.
3. Slow Simmer to Tenderness: Cover and cook on LOW for 6 to 7 hours (or HIGH for 3 to 4 hours) until the bell peppers are tender and the flavors have melded into deep savory comfort.
4. Stir in Fluffy Rice: Add 2 cups of warm cooked white rice during the final 20 to 30 minutes of cooking on LOW so the grains absorb just enough broth without turning soft.
5. Garnish & Serve: Ladle generous hot bowls, crown with shredded sharp cheddar cheese, sprinkle with chopped parsley, and serve immediately!
3 Chef Secrets for Perfect Results
1. Never Cook Dry Rice Directly in the Slow Cooker: Dry uncooked rice acts like a sponge and will drink up almost all your flavorful tomato broth, transforming your soup into a thick sludge. Always cook your rice separately and stir it in right before serving.
2. Brown the Beef with High Heat Fond: Don’t just boil raw ground beef in the crockpot. Searing it in a hot skillet caramelizes the exterior meat sugars (the Maillard reaction), creating savory fond that enriches the broth dramatically.
3. Keep Peppers at 1/2-Inch Size: Don’t mince the peppers too fine! A sturdy 1/2-inch dice allows them to retain a pleasant, tender bite throughout hours of slow cooking without disintegrating.
What to Serve With Stuffed Pepper Soup
- Toasted Sourdough or Garlic Bread: Crusty artisan sourdough or warm garlic ciabatta is essential for dunking into the thick, savory tomato broth.
- Crisp Autumn Garden Salad: A crisp side salad of mixed greens, shaved cucumbers, and lemon vinaigrette cuts through the rich, comforting beef.
- Gooey Grilled Cheese Dipper: For the ultimate cozy lunchtime feast, pair a steaming bowl with a sharp cheddar and sourdough grilled cheese!
Storage, Freezing & Reheating Instructions
- Refrigeration: Allow soup to cool completely and store in airtight glass containers for up to 4 days. If storing with rice, the rice will continue to thicken the broth; simply splash in a little extra beef broth when reheating!
- Stovetop Reheating: Reheat gently in a saucepan over medium heat for 5 to 7 minutes until bubbling. Microwave in 1-minute intervals, stirring halfway through.
- Freezing (Best Without Rice): Freeze the soup base (without rice) in freezer bags or containers for up to 3 months. Thaw overnight in the fridge, heat to a simmer, and stir in freshly steamed rice right before serving for bakery-fresh texture!
Slow-Cooker Stuffed Bell Pepper Soup with Ground Beef and Rice
Ingredients
Method
- Brown the Beef & Aromatics: Heat olive oil in a large skillet over medium-high heat. Add the ground beef and diced onion. Cook for 6 to 8 minutes, breaking up the meat with a wooden spoon, until browned and cooked through. Add minced garlic and cook for 1 minute until fragrant. Drain off any excess grease and transfer meat mixture to a 6-quart slow cooker.
- Load the Slow Cooker: Add chopped bell peppers, crushed fire-roasted tomatoes, tomato sauce, beef broth, tomato paste, Worcestershire sauce, Italian seasoning, smoked paprika, garlic powder, onion powder, salt, and black pepper. Stir well until the tomato paste dissolves into the broth.
- Slow Simmer: Cover with the lid and cook on LOW for 6 to 7 hours, or on HIGH for 3 to 4 hours, until the bell peppers are tender and the rich tomato-beef broth has deeply developed its comforting flavor.
- Incorporate the Rice: Stir the cooked white rice into the slow cooker during the last 20 to 30 minutes of cooking on LOW so the rice absorbs the savory broth without getting mushy. (Pro-tip: If you plan to freeze or store leftovers, spoon cooked rice directly into individual serving bowls and ladle the hot soup over top!)
- Adjust Seasoning & Serve: Taste and adjust salt and pepper if needed. Ladle generous steaming bowls of soup, top each with a generous handful of shredded sharp cheddar cheese and fresh chopped parsley, and serve with crusty sourdough bread!
