It’s deeply satisfying, budget-friendly, and built for real weeknight life. If you’ve been searching for an easy stuffed pepper soup that doesn’t compromise on flavor, you’ve found it.

What Makes This Recipe Special

• True one-pot simplicity: From browning the beef to simmering the rice, everything happens in a single pot. Fewer dishes, more time for the things that matter.
• All the stuffed pepper flavor, none of the fuss: This stuffed bell pepper soup recipe delivers the same cozy, layered taste as the classic dish without any tedious assembly.
• Weeknight-ready timing: The whole pot comes together in about 45 minutes, making it a strong contender for your regular dinner rotation.
• Incredibly flexible: Works beautifully as a stuffed bell peppers with tomato soup variation, and adapts easily to whatever peppers, proteins, or grains you have on hand.

What You’ll Need

• Ground beef (1 lb, 80/20): The fat content adds richness to the broth. Lean beef works too but may need a splash of olive oil.
• Bell peppers (3 medium, mixed colors): Red, yellow, and orange bring natural sweetness. Green peppers add a slightly bitter, earthy note that balances the tomato base.
• Yellow onion (1 medium, diced): Builds the savory foundation of the soup.
• Garlic (4 cloves, minced): Don’t skip it. Fresh garlic makes a real difference here.
• Crushed tomatoes (1 can, 28 oz): The backbone of your stuffed bell pepper soup recipe. Fire-roasted crushed tomatoes add an extra layer of depth.
• Beef broth (4 cups): Creates body and richness. Low-sodium lets you control the salt level.
• Tomato paste (2 tablespoons): Intensifies and concentrates the tomato flavor.
• Long-grain white rice (3/4 cup, uncooked): Cooks right in the soup and thickens it naturally as it absorbs broth.
• Italian seasoning (1 1/2 teaspoons): Adds herbaceous warmth throughout.
• Smoked paprika (1 teaspoon): Gives the soup subtle smoky complexity.
• Salt and black pepper: To taste, added in layers as you cook.
• Worcestershire sauce (1 tablespoon): A quiet background note that deepens the savory quality of the broth.
• Shredded mozzarella or cheddar (for serving, optional): Because a melty cheese situation on top of soup is never a bad call.

Using the right heavy-bottomed pot makes all the difference in one-pot cooking, keeping heat even and preventing scorching on the bottom while your soup simmers. A quality Dutch oven or large soup pot is genuinely worth the investment for recipes like this one.

Equipment

• Large Dutch oven or heavy-bottomed pot
• Wooden spoon or spatula
• Ladle
• Cutting board and chef's knife

Ingredients

  

• 1 lb ground beef (80/20)
• 3 medium bell peppers, diced (mixed colors) red, yellow, and orange recommended
• 1 medium yellow onion, diced
• 4 cloves garlic, minced
• 1 can (28 oz) crushed tomatoes fire-roasted for extra depth
• 4 cups beef broth low-sodium preferred
• 2 tablespoons tomato paste
• 3/4 cup long-grain white rice, uncooked
• 1 1/2 teaspoons Italian seasoning
• 1 teaspoon smoked paprika
• 1 tablespoon Worcestershire sauce
• 1 teaspoon salt plus more to taste
• 1/2 teaspoon black pepper plus more to taste
• 1 cup shredded mozzarella or cheddar cheese optional, for serving

Instructions

 

• Heat a large Dutch oven or heavy-bottomed pot over medium-high heat. Add the ground beef and cook for 6 to 8 minutes, breaking it apart with a wooden spoon, until fully browned with no pink remaining. Drain excess fat, leaving about one tablespoon in the pot.
• Reduce heat to medium. Add the diced onion and bell peppers to the pot with the beef. Cook for 4 to 5 minutes, stirring occasionally, until the onion is translucent and the peppers begin to soften.
• Stir in the minced garlic and tomato paste. Cook for 1 to 2 minutes, stirring constantly, until the tomato paste darkens slightly and the garlic is fragrant.
• Pour in the crushed tomatoes and beef broth. Add the Worcestershire sauce, Italian seasoning, smoked paprika, salt, and black pepper. Stir thoroughly to combine and bring the soup to a gentle boil over medium-high heat.
• Stir in the uncooked rice. Reduce heat to medium-low, cover the pot, and simmer for 18 to 20 minutes, stirring once or twice during cooking, until the rice is tender and has absorbed some of the broth.
• Taste the soup and adjust seasoning with additional salt, pepper, or smoked paprika as needed. Ladle into bowls and top with shredded cheese if desired. Serve immediately with crusty bread on the side.

Notes

For meal prep, store the soup and rice separately to prevent the rice from absorbing too much broth. The soup thickens as it sits; add a splash of broth when reheating. Freeze without rice for best results, up to 3 months. Do not add rice too early or before the broth reaches a simmer, as this can cause uneven cooking and a gluey texture.

Try These Variations

• Turkey or chicken swap: Replace the ground beef with ground turkey or chicken for a lighter stuffed pepper soup recipe that still feels hearty and satisfying.
• Brown rice or quinoa: Both work well in place of white rice. Add 10 to 15 extra minutes of simmer time and a splash more broth since they absorb more liquid.
• Vegetarian version: Skip the meat entirely and double the bell peppers. Add a can of drained black beans or chickpeas for protein. Use vegetable broth instead of beef broth.
• Spicy kick: Stir in a pinch of crushed red pepper flakes or a diced jalapeño with the onions for a bell pepper soup recipe with some heat behind it.

How to Make Best One-Pot Stuffed Pepper Soup

• Brown the beef: Heat a large Dutch oven or heavy pot over medium-high heat. Add the ground beef and cook for 6 to 8 minutes, breaking it apart with a wooden spoon, until fully browned with no pink remaining. Drain excess fat if needed, leaving about a tablespoon in the pot for flavor.
• Soften the aromatics: Reduce heat to medium. Add the diced onion and bell peppers to the pot. Cook for 4 to 5 minutes, stirring occasionally, until the onion turns translucent and the peppers begin to soften at the edges.
• Add garlic and tomato paste: Stir in the minced garlic and tomato paste. Cook for 1 to 2 minutes, stirring constantly, until the paste darkens slightly and smells fragrant. This step builds serious depth in your stuffed bell pepper soup.
• Build the broth: Pour in the crushed tomatoes and beef broth. Add the Worcestershire sauce, Italian seasoning, smoked paprika, salt, and pepper. Stir everything together thoroughly and bring the pot to a gentle boil over medium-high heat.
• Add the rice and simmer: Stir in the uncooked rice, then reduce heat to medium-low. Cover the pot and simmer for 18 to 20 minutes, stirring once or twice, until the rice is tender and has absorbed some of the broth. The soup will thicken as it sits.
• Taste and adjust: Give the soup a final taste and adjust seasoning with salt, pepper, or a pinch more smoked paprika. Ladle into bowls and top with shredded cheese if using.

Expert Tips

• Don’t overcook the rice: Rice continues absorbing liquid even after the heat is off. Pull the pot from the burner when the rice is just tender to avoid a starchy, thick texture by the next day.
• Add rice separately for meal prep: If you plan to store leftovers, cook the rice separately and stir it in per bowl at serving time. This keeps the broth from getting too thick.
• Layer your seasoning: Season the beef while it browns, season again after adding broth, and taste once more at the end. This builds flavor at every stage rather than dumping everything in at once.
• Common mistake to avoid: Adding rice too early. Wait until the broth is fully simmering before adding it, so the rice cooks evenly and doesn’t get mushy or gluey at the bottom of the pot.

Serving Suggestions

• Crusty bread or dinner rolls: Perfect for soaking up every last drop of the tomato broth. A thick slice of sourdough alongside this stuffed bell pepper soup is a complete meal.
• Cheese on top: A generous handful of shredded mozzarella, cheddar, or pepper jack melted over the hot soup takes it from weeknight dinner to something that feels a little special.
• Fresh herbs: A scatter of fresh parsley or basil brightens the richness of the tomato base and adds a nice visual finish.
• Sour cream swirl: A dollop of sour cream stirred in adds creaminess and a gentle tang that plays beautifully against the savory broth.

Make Ahead and Storage

• Refrigerator: Store cooled soup in an airtight container for up to 4 days. The rice will continue absorbing liquid as it sits, so add a splash of broth when reheating to loosen the texture.
• Freezer: Freeze in individual portions in freezer-safe containers or zip-lock bags for up to 3 months. For best results, freeze the soup without the rice and cook fresh rice when you reheat.
• Reheating: Warm on the stovetop over medium heat, stirring occasionally, for 8 to 10 minutes. Add broth or water as needed to reach your preferred consistency. Microwave reheating works well too, about 2 to 3 minutes on high with a splash of broth stirred in.

Frequently Asked Questions

Can I use instant rice instead of regular rice?
Yes, but add it in the last 5 minutes of cooking rather than at the beginning. Instant rice cooks much faster and will turn to mush if simmered for the full 18 to 20 minutes.

What’s the difference between this and traditional stuffed bell peppers with tomato soup?
The flavors are nearly identical. This unstuffed bell pepper soup simply skips the assembly step, tossing everything directly into the pot instead of filling individual peppers. It’s faster, easier, and just as satisfying.

Can I make this in a slow cooker?
Absolutely. Brown the beef and soften the aromatics on the stovetop first, then transfer everything except the rice to the slow cooker. Cook on low for 6 to 7 hours or high for 3 to 4 hours, then stir in cooked rice during the last 30 minutes.

Why is my soup too thick?
The rice absorbs a lot of liquid as the soup sits. Just stir in extra broth, a half cup at a time, until the soup reaches the consistency you like. This is completely normal and easy to fix.
