Stuffed Pepper Soup Recipe

Stuffed Pepper Soup brings all the cozy flavors of classic stuffed peppers to the table in a much easier one-pot format. Instead of stuffing individual peppers and baking them, everything simmers together in a rich tomato and beef broth, then gets finished with tender white rice and fresh parsley.

The combination of lean ground beef, colorful bell peppers, tomatoes, garlic, and Italian seasoning gives this soup plenty of savory flavor. Worcestershire sauce adds depth, while a small amount of sugar can balance the acidity of the tomatoes when needed.

It is especially good on chilly evenings when you want something filling without spending hours in the kitchen. Add a little shredded cheddar or mozzarella to each bowl for a comforting cheesy finish.

Ingredients

For the Soup

• 1 lb. lean ground beef
• 1 tablespoon olive oil, divided
• 1/2 medium yellow onion, diced, about 1/2 cup
• 2 cloves garlic, minced
• 1 red bell pepper, finely chopped
• 1 green bell pepper, finely chopped
• 2 (14.5-ounce) cans diced tomatoes
• 1 (15-ounce) can tomato sauce
• 2 cups beef broth
• 1 tablespoon Worcestershire sauce
• 1 tablespoon sugar, or to taste, optional
• 1 teaspoon Italian seasoning
• Salt and black pepper, to taste
• 2 cups cooked long-grain white rice
• 2 tablespoons fresh Italian parsley, chopped
• Shredded cheddar or mozzarella cheese, for serving, optional

How to Make Stuffed Pepper Soup

1. Brown the Ground Beef

Heat a large Dutch oven or heavy-bottomed soup pot over medium-high heat. Add about half of the olive oil, followed by the lean ground beef.

Cook for about 5–7 minutes, breaking the beef apart with a wooden spoon as it cooks. Continue until it is browned and no longer pink.

If there is a lot of excess fat in the pot, carefully drain it before continuing. Lean ground beef usually does not require much draining.

2. Cook the Onion and Peppers

Add the remaining olive oil to the pot if needed. Stir in the diced yellow onion, chopped red bell pepper, and chopped green bell pepper.

Cook for about 5 minutes, stirring occasionally, until the vegetables begin to soften.

The peppers should become tender but still retain a little texture. This gives the finished soup more character than cooking them until completely soft.

3. Add the Garlic and Seasonings

Stir in the minced garlic and cook for about 30 seconds, just until fragrant.

Add the Italian seasoning, Worcestershire sauce, a little salt, and black pepper. Stir well so the seasonings coat the beef and vegetables.

Be careful with the salt at this stage because the canned tomatoes, beef broth, and Worcestershire sauce can all contribute saltiness.

4. Add the Tomatoes and Broth

Pour in the diced tomatoes, tomato sauce, and beef broth. Stir everything together, scraping the bottom of the pot if necessary.

If your tomatoes taste particularly acidic, add the sugar. Start with a smaller amount if you prefer and adjust later. The sugar is not meant to make the soup sweet; it simply helps round out sharp tomato acidity.

Bring the soup to a gentle boil.

5. Simmer the Soup

Once the soup reaches a boil, reduce the heat to medium-low and let it simmer uncovered for about 20–25 minutes.

Stir occasionally while it cooks.

This simmering time allows the peppers and onions to become tender while the beef, tomatoes, broth, and seasonings develop a deeper flavor.

Taste the broth toward the end of cooking and adjust the salt, pepper, Italian seasoning, or sugar if necessary.

6. Add the Cooked Rice

Since the rice is already cooked, add the 2 cups of cooked long-grain white rice toward the end rather than simmering it from the beginning.

Stir the rice into the soup and cook for about 3–5 minutes, just until it is heated through.

Adding cooked rice at this stage helps prevent it from becoming overly soft and absorbing too much of the broth.

7. Finish with Fresh Parsley

Remove the pot from the heat and stir in the chopped fresh Italian parsley.

Taste one final time and adjust the seasoning.

Ladle the soup into bowls and top with shredded cheddar or mozzarella cheese if desired. Serve hot.

Tips for the Best Stuffed Pepper Soup

Use both red and green bell peppers

The two peppers bring slightly different flavors to the soup. Red bell peppers are naturally sweeter, while green peppers have a more savory, slightly bitter flavor.

Using both also gives the soup a nice balance of color and flavor.

Brown the beef properly

Let the ground beef cook long enough to develop some browning rather than immediately stirring it constantly. Those browned bits add extra savory flavor to the finished soup.

Don’t overcook the peppers

You want the peppers to be tender but not completely mushy. A short sauté before adding the liquid helps them develop flavor while the later simmer finishes cooking them.

Add rice near the end

Cooked rice does not need to simmer for a long time. Adding it during the final few minutes keeps the grains more distinct and leaves more broth in the soup.

If the soup becomes too thick after sitting, simply stir in a little extra beef broth when reheating.

Taste before adding more salt

Canned tomatoes, beef broth, Worcestershire sauce, and cheese can all contain sodium. Taste the soup after simmering and adjust the seasoning gradually.

Balance the tomatoes

Some canned tomatoes are noticeably more acidic than others. If the finished broth tastes too sharp, a small amount of sugar can help balance it. Add it gradually rather than automatically using the full tablespoon.

Ingredient Substitutions

Ground beef

Lean ground beef works especially well, but you can use regular ground beef if you prefer. Ground turkey can also be substituted for a lighter version.

White rice

Long-grain white rice is ideal for this recipe, but cooked basmati or jasmine rice can work too. Brown rice is another option if you prefer a heartier texture.

Bell peppers

Red and green peppers are the classic combination here, but yellow or orange bell peppers can replace either one. Using a mixture of colors gives the soup a slightly sweeter flavor.

Beef broth

Use low-sodium beef broth if available, especially if you want more control over the salt level. Chicken or vegetable broth can work in a pinch, although beef broth gives the soup a richer flavor.

Cheese

Cheddar and mozzarella are both good choices. Monterey Jack or a Mexican-style cheese blend can also work if you want a different finish.

Worcestershire sauce

If you do not have Worcestershire sauce, you can leave it out, although the soup will lose some of its savory depth. A small splash of soy sauce can provide a similar umami effect.

Stuffed Pepper Soup Variations

Cheesy Stuffed Pepper Soup

For a richer bowl, stir a small amount of shredded cheddar directly into the soup after adding the rice. Keep the heat low and stir until the cheese melts.

You can also simply sprinkle cheese over each serving.

Spicy Stuffed Pepper Soup

Add a pinch of crushed red pepper flakes, a diced jalapeño, or a little hot sauce along with the seasonings.

The heat works particularly well with the sweetness of the red bell pepper and tomato base.

Turkey Stuffed Pepper Soup

Replace the ground beef with lean ground turkey. Use chicken broth instead of beef broth if you want the flavor profile to be lighter.

Brown Rice Stuffed Pepper Soup

Cook brown rice separately and stir it into the soup near the end. Because brown rice takes longer to cook, preparing it separately keeps the soup from becoming overcooked.

Extra Vegetable Stuffed Pepper Soup

Add diced carrots, zucchini, mushrooms, or celery along with the bell peppers. Keep the vegetable additions moderate so the soup maintains its classic stuffed-pepper flavor.

Creamy Stuffed Pepper Soup

For a creamy variation, stir in a small splash of heavy cream after the soup has finished simmering. Keep the heat low and avoid boiling once the cream has been added.

Can You Make Stuffed Pepper Soup Ahead of Time?

Yes. This soup is a good make-ahead meal because the flavors continue to develop as it rests.

If you are intentionally preparing it ahead, you can keep the cooked rice separate and add it to individual portions when serving. This prevents the rice from absorbing too much broth while the soup sits in the refrigerator.

If the rice is already mixed into the soup, expect the soup to become thicker overnight.

How to Store Stuffed Pepper Soup

Allow the soup to cool before transferring it to airtight containers.

Store it in the refrigerator for up to 4 days.

For the best texture, store the rice separately when possible. If the rice is already mixed in, simply add a splash of beef broth when reheating if the soup has become too thick.

How to Reheat Stuffed Pepper Soup

Reheat individual portions in the microwave in short intervals, stirring between each one.

For larger quantities, warm the soup gently in a saucepan or pot over medium-low heat. Stir occasionally and add a little extra broth if necessary.

Avoid cooking it at a rapid boil during reheating, especially if the rice is already mixed into the soup.

Can You Freeze Stuffed Pepper Soup?

Yes, but the texture of the rice may become softer after freezing and thawing.

For the best results, prepare and freeze the soup without the cooked rice. Allow the soup to cool completely, transfer it to freezer-safe containers, and leave a little room for expansion.

Freeze for up to about 3 months for the best quality.

Thaw overnight in the refrigerator, reheat gently, and add freshly cooked rice before serving.

What to Serve with Stuffed Pepper Soup

This soup is filling enough to serve as a complete meal, but a simple side can make it even more satisfying.

Try serving it with:

• Crusty French bread
• Garlic bread
• Dinner rolls
• A simple green salad
• Roasted vegetables
• Cornbread
• Crackers
• A sprinkle of fresh parsley
• Shredded cheddar or mozzarella

A piece of crusty bread is especially useful for soaking up the tomato-rich broth.

Frequently Asked Questions

Can I use uncooked rice in stuffed pepper soup?

Yes, but the cooking method needs to be adjusted. Uncooked rice requires additional liquid and cooking time, so it is generally easier to cook the rice separately for this particular recipe.

Using cooked rice also gives you better control over the final texture.

Why is my stuffed pepper soup too thick?

Rice naturally absorbs liquid, especially as the soup cools. If your soup becomes too thick, stir in additional beef broth until it reaches the consistency you like.

Can I make this soup without rice?

Absolutely. The soup will still have plenty of flavor from the beef, peppers, tomatoes, and seasonings. You can replace the rice with cooked quinoa, cauliflower rice, or another grain, or simply leave it out.

Can I use different colored bell peppers?

Yes. Yellow and orange bell peppers are excellent substitutions for red or green peppers. They tend to be sweeter than green peppers.

Can I make stuffed pepper soup in a slow cooker?

Yes, although the ground beef should ideally be browned first for better flavor. Add the browned beef, vegetables, tomatoes, tomato sauce, broth, and seasonings to the slow cooker and cook until the vegetables are tender.

Add the cooked rice near the end so it does not become overly soft.

How do I make the soup less acidic?

First, taste the soup after it has simmered. If the tomato flavor is particularly sharp, add a small amount of sugar and stir well. Taste again before adding more.

Using sweet red bell pepper also naturally helps balance the tomato base.

What cheese is best for stuffed pepper soup?

Cheddar gives the soup a stronger, sharper flavor, while mozzarella melts into a mild and stretchy topping. Either works well, so the choice comes down to personal preference.

Final Thoughts

Stuffed Pepper Soup takes everything that makes classic stuffed peppers comforting and turns it into a simple, hearty bowl of soup. Ground beef, red and green bell peppers, tomatoes, and Italian seasoning create a flavorful base, while cooked rice makes each serving substantial without requiring a complicated preparation.

The recipe is flexible enough for weeknight dinners, meal prep, or a cozy weekend meal. Keep the rice separate if you plan to store the soup, adjust the tomato balance to your taste, and finish each bowl with fresh parsley and a little shredded cheese.
