Ingredients
For the Soup:
- 1½ lbs lean ground beef (90/10)
- 1 large yellow onion, diced
- 3 cloves garlic, minced
- 3 bell peppers, diced (a mix of red, green, yellow, or orange)
- 1 (15 oz) can tomato sauce
- 1 (14.5 oz) can diced tomatoes, undrained
- 3 cups low-sodium beef broth
- 1 tablespoon tomato paste
- 1 tablespoon Worcestershire sauce
- 1½ teaspoons Italian seasoning
- 1 teaspoon sweet paprika (not smoked)
- ½ teaspoon dried oregano
- ½ teaspoon salt, plus more to taste
- ½ teaspoon black pepper
- 1 teaspoon brown sugar
- Pinch of red pepper flakes (optional)
For the Rice:
- 1 cup uncooked long-grain white rice
- Water and salt, for cooking
For Serving:
- Fresh parsley, chopped
- Grated Parmesan cheese (optional)
- Crusty bread
Instructions
- Brown the ground beef: Heat a large skillet over medium-high heat. Add the ground beef and diced onion and cook for 7 to 8 minutes, breaking up the beef with a spoon, until the meat is browned and the onion has softened. Drain excess fat if needed.
- Add the garlic: Stir in the garlic and cook for 30 to 60 seconds, just until fragrant.
- Build the soup: Transfer the beef mixture to a 6-quart slow cooker. Add the diced bell peppers, tomato sauce, diced tomatoes with their juices, beef broth, tomato paste, Worcestershire sauce, Italian seasoning, paprika, oregano, salt, black pepper, brown sugar, and red pepper flakes (if using). Stir well to combine.
- Cook: Cover and cook on LOW for 4 to 5 hours or on HIGH for 2½ to 3 hours, until the bell peppers are tender but still hold their shape and the flavors have melded.
- Cook the rice: About 30 minutes before serving, cook the rice separately according to the package directions. Fluff with a fork once tender.
- Finish the soup: Taste the soup and adjust the seasoning with additional salt, black pepper, or a little Worcestershire sauce if needed.
- Serve: Spoon about ⅓ to ½ cup cooked rice into each bowl. Ladle the hot stuffed pepper soup over the rice, making sure each serving gets plenty of ground beef and bell peppers. Garnish with fresh parsley and Parmesan cheese, if desired. Serve immediately with crusty bread.
Tips for the Best Stuffed Pepper Soup
- Use a mix of bell pepper colors. Red, orange, yellow, and green peppers add more color to the soup and make the finished dish look more like a classic stuffed pepper.
- Brown the beef first. This adds more flavor and prevents the ground beef from becoming gray and crumbly in the slow cooker.
- Cook the rice separately. Rice continues absorbing liquid as it sits, so cooking it separately keeps the soup brothy and prevents leftovers from becoming too thick. This is the most important tip for the best texture.
- Don’t overcook the peppers. The peppers should be tender enough to eat easily but still visible and slightly textured — not completely dissolved into the broth.
- The tomato paste matters. It adds concentrated tomato flavor and gives the broth a richer, deeper color.
- Add the rice to individual bowls. This gives you better control over the soup-to-rice ratio and creates the distinct rice grains shown in the finished dish.
- Adjust the sweetness carefully. The teaspoon of brown sugar should not make the soup sweet. It simply balances the tomatoes’ acidity and recreates the familiar flavor profile of stuffed peppers.
- Store rice separately for leftovers. Refrigerate the soup and rice in separate containers, then combine when reheating for the best texture.
Easy Variations
- Use ground turkey or chicken: Swap ground beef for ground turkey or chicken for a lighter version.
- Make it spicier: Add ½ teaspoon red pepper flakes or a diced jalapeño.
- Add extra vegetables: Stir in diced zucchini, mushrooms, or carrots.
- Make it with Italian sausage: Use 1.5 lbs of Italian sausage (casings removed) instead of ground beef for a different flavor.
- Make it low-carb: Skip the rice and add extra vegetables or serve over cauliflower rice.
- Make it with brown rice: If you prefer brown rice, cook it separately — it takes longer but works well.
Storage and Reheating
- Refrigerate: Store leftover soup in an airtight container in the fridge for up to 5 days. The flavors deepen as it sits.
- Freeze: This stuffed pepper soup freezes well for up to 3 months. Cool completely, transfer to a freezer-safe container, and freeze. Thaw overnight in the fridge before reheating.
- Reheat: Warm gently on the stovetop over medium-low heat or in the microwave. Add a splash of broth if the soup has thickened too much.

- A simple green salad with Italian dressing

Frequently Asked Questions
Can I cook the rice directly in the slow cooker?
I don’t recommend it. Rice can absorb too much liquid, cook unevenly, and make leftovers thick and mushy. Cooking it separately gives you perfect rice every time and better control over the soup’s texture.
Can I use different types of rice?
Yes — long-grain white rice works best. Brown rice can also be used but requires a longer cooking time. If using instant rice, cook it separately according to package directions.
Can I use ground turkey instead of beef?
Yes — ground turkey or chicken works well as a substitute. Add a little extra oil to the pan when browning since they’re leaner than ground beef.
Why is my soup too thick?
The soup may thicken as it sits. If you prefer a thinner soup, stir in an extra cup of broth or water before serving.
Can I make this in the Instant Pot instead?
Yes — use the sauté function to brown the beef and onion, then add the remaining ingredients (except the rice). Cook on HIGH pressure for 10 minutes—quick release. Cook the rice separately and serve the soup over it.
How do I prevent the peppers from getting mushy?
Add the peppers at the beginning — they’ll become tender but still hold their shape. Avoid overcooking beyond the recommended time.
Can I freeze this soup?
Yes — this soup freezes well for up to 3 months. The rice (if stored separately) may soften slightly. Cool completely, transfer to a freezer-safe container, and freeze. Thaw overnight in the fridge before reheating.
How long does this soup last in the fridge?
Stored in an airtight container, this soup lasts up to 5 days in the fridge. The flavors deepen over time.
Is this soup high protein?
Yes — each serving has about 30g of protein, thanks to the ground beef and broth.
Can I make this soup in a slow cooker without browning the beef first?
You can, but I don’t recommend it. Browning the beef adds significant depth of flavor. If you’re short on time, you can skip it, but the soup will have a milder flavor.
