This is the soup I make when I want dinner to take care of itself. When the slow cooker hums softly on the counter, doing the heavy lifting while I go about my day, I feel like I'm being looked after. By the time the rice goes in at the end, the broth is rich, the vegetables are tender, and the beef has shared every bit of its savory goodness. One ladle in, and suddenly, it's like sitting down to a familiar meal only easier, warmer, and somehow even better.

Key Benefits

This Slow Cooker Stuffed Pepper Soup Recipe is one of those rare meals that checks all the boxes:

• Minimal prep and hands-off cooking
• Budget-friendly ingredients
• Feeds a crowd or stretches into leftovers
• Perfect for busy weekdays or relaxed weekends

Once the beef is browned, everything else goes straight into the slow cooker. From there, time does the work, transforming simple ingredients into something deeply satisfying.

Taste & Texture

This soup is savory, tomato-forward, and gently herby. The bell peppers add sweetness, the onion melts into the broth, and the fire-roasted tomatoes bring a subtle smokiness. When the rice is added at the end, it plumps up beautifully, giving the soup a comforting, stew-like body without becoming mushy.

A final sprinkle of mozzarella creates little pockets of creamy richness like the best part of stuffed peppers, but in every bite.

Dietary Attributes

• High in protein
• Naturally gluten-free (with gluten-free rice)
• Easy to adapt for lower sodium or leaner diets

It's filling without being heavy, making it ideal for family dinners or meal prep.

Ingredients & Substitutions

Ingredient List

• 1 lb ground beef, browned, crumbled, and drained
• 1 red bell pepper, diced
• 1 green bell pepper, diced
• 1 sweet yellow onion, diced
• 2 garlic cloves, minced
• 30 oz chicken broth (about 4 cups)
• 15 oz tomato sauce (not paste)
• 14.5 oz fire-roasted diced tomatoes, undrained
• 1 teaspoon oregano (or Italian seasoning)
• ½ teaspoon dried basil
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ½ cup uncooked Minute Brand Rice (added at the end)
• Mozzarella cheese, for serving (optional)

Notes on Quality

Fresh bell peppers make a noticeable difference here their sweetness balances the acidity of the tomatoes. Fire-roasted diced tomatoes add depth, but regular diced tomatoes will still deliver a delicious result.

Minute Rice is essential for this recipe. Because it's parboiled and dried, it cooks quickly and absorbs flavor without turning gummy.

Possible Substitutions

• Ground turkey or chicken for a lighter option
• Vegetable broth instead of chicken broth
• Brown Minute Rice (adjust final cook time slightly)
• Dairy-free cheese or no cheese at all

Step-by-Step Instructions

1. Brown the ground beef in a skillet over medium heat until fully cooked. Drain excess fat.
2. Add the browned beef to the slow cooker.
3. Add diced red and green bell peppers, onion, and garlic.
4. Pour in chicken broth, tomato sauce, and fire-roasted diced tomatoes.
5. Stir in oregano, basil, salt, and pepper.
6. Cover and cook on HIGH for 4 hours or LOW for 8 hours.
7. When cooking time is complete, stir in the uncooked Minute Rice.
8. Cover again and cook on HIGH for 20 minutes.
9. Stir well and serve hot, topped with mozzarella if desired.

The rice finishes the soup at the very end, soaking up flavor while keeping the texture just right.
