This guide provides a foolproof recipe and answers all your questions, from preventing watery results to the best way to cut the peppers. I promise a recipe with a surprisingly savory and juicy filling that is simple enough for a weeknight but absolutely delicious enough for guests.

Why You’ll Love This Recipe

This recipe stands out because of a few simple but game-changing details that create the best flavor and texture.

Our Secret for the Most Flavorful Filling

The magic is in two key ingredients: tomato paste and Worcestershire sauce. We add a touch of tomato paste to the filling and sauté it to deepen the tomato flavor and add a caramelized sweetness. The Worcestershire sauce adds a rich, savory umami note that makes the ground beef taste even beefier and more complex.

Incredibly Flavorful

That special umami twist from the tomato paste and Worcestershire sauce makes all the difference, creating a filling that is deeply savory and memorable.

Perfectly Tender Peppers

We pre-roast the peppers instead of boiling them. This enhances their natural sweetness and results in a perfect tender-crisp texture that holds up to the hearty filling.

Meal-Prep and Freezer-Friendly

This is a fantastic make-ahead recipe for busy weeks. You can prepare them in advance and they freeze beautifully, making weeknight dinner a breeze.

Classic Comfort Food

This is a satisfying and cheesy weeknight dinner that the whole family will love. It is a complete meal in one delicious package.

Ingredients Needed

Here is what you will need to gather for this recipe. The list is simple, and the results are fantastic.

• 1 pound 90% lean ground beef
• 1¼ teaspoons salt, divided
• Heaping ¼ teaspoon baking soda
• 3 large red, yellow, or orange bell peppers, cut in half from the stem to the bottom and cored
• 3 tablespoons extra-virgin oil
• 1 medium yellow onion, finely chopped
• 3 cloves garlic, minced
• 1½ teaspoons chili powder
• ½ teaspoon ground cumin
• ¼ teaspoon dried oregano
• 1 (8-oz) can tomato sauce
• 1 cup cooked rice, quinoa, or any grain
• 1½ cups shredded Monterey Jack or Cheddar Jack cheese

Ingredient Notes and Substitutions

A few notes on the key ingredients can help you get the best results or make smart swaps.

Bell Peppers: I highly recommend using red, yellow, or orange bell peppers for this recipe. They are much sweeter and have a milder flavor than green bell peppers, which can sometimes be slightly bitter. Learn more about the flavor differences in bell pepper colors.

Ground Beef: A 90% lean ground beef works perfectly here as it has enough fat for flavor without making the filling greasy, so you will not need to drain it. If you only have 80/20 ground beef, you can certainly use it, but you may want to drain off some of the excess fat after browning it.

Rice: Any cooked grain will work beautifully in the filling. I often use long-grain white rice because it holds its shape well, but cooked quinoa, brown rice, or even farro are excellent substitutes.

Cheese: Pre-shredded Monterey Jack or a Cheddar Jack blend is convenient and melts well. If you have a block of cheese, grating it yourself will result in an even smoother, creamier melt.

Baking Soda: This might seem like an unusual ingredient, but it is my secret to incredibly tender ground beef. A tiny amount helps to raise the pH of the meat, preventing it from getting tough as it cooks. You can read more about why you should add baking soda when cooking ground beef.

How to Make Stuffed Bell Peppers with Ground Beef

Follow these simple steps for perfect stuffed peppers every single time.

Step 1: Prep Oven and Peppers

First, preheat your oven to 425°F and set an oven rack in the middle position. This high heat helps the peppers roast perfectly. Place the bell pepper halves cut-side up in a 9×13-inch baking dish. For easy cleanup later, I recommend lining the baking dish with aluminum foil. Drizzle the peppers with a tablespoon of oil and sprinkle them with a quarter teaspoon of salt to season them from the start.

Step 2: Tenderize the Beef

In a medium bowl, use your hands to gently mix the ground beef with one teaspoon of salt and the baking soda. Let this mixture sit for about 20 minutes while you prepare the other components. This simple step is the key to ensuring your incredibly tender ground beef filling is juicy and tender, not dry or tough.

Step 3: Pre-Roast the Peppers

Place the baking dish with the peppers into the preheated oven. Roast them for about 20 minutes. You are looking for them to be slightly browned and tender-crisp, meaning a fork can pierce them with a little resistance. It is normal for a bit of liquid to pool in the bottom of the peppers; we will deal with that later.

Step 4: Build the Flavorful Filling

While the peppers are roasting, heat the remaining two tablespoons of oil in a large skillet over medium heat. Add the finely chopped yellow onion and cook until it is soft and translucent. Next, add the minced garlic and cook for just one minute more until it becomes fragrant. Be careful not to let it brown.

Now, add the ground beef mixture to the skillet along with the chili powder, cumin, and oregano. Increase the heat to medium-high and cook, breaking the meat apart with a spoon, until it is browned. Pour in the tomato sauce and bring it to a boil. Reduce the heat and let it simmer for a few minutes. Finally, stir in the cooked rice and about half of the shredded cheese until it is melted and creamy. Remove the skillet from the heat.

Step 5: Stuff and Bake

Carefully remove the peppers from the oven. You can pat the insides dry with a paper towel to remove excess moisture. Spoon the beef and rice filling evenly into each pepper half. Top them generously with the remaining shredded cheese. Place the dish back into the oven and bake for another 10 to 15 minutes. The stuffed bell peppers are done when the filling is hot all the way through and the cheese on top is melted, bubbly, and slightly golden.

Choosing Your Cut: Halves vs. Whole Peppers

How you cut your peppers can change the cooking time and presentation. Both ways work, but I have a clear favorite.

Halved Lengthwise (Our Method)

Cutting the peppers in half from the stem to the bottom is my recommended method. This creates a wide, stable boat for the filling. It is much easier to stuff, the peppers cook more evenly, and you get a better ratio of cheesy topping in every single bite.

Tops Removed (Standing Up)

The other popular method is to slice off the tops of the peppers and core them, leaving them whole so they can stand up. This creates a beautiful presentation, but it can be tricky to get the peppers to stay upright in the baking dish. They also tend to require a slightly longer cooking time to become fully tender.

Customizing Your Filling: Low-Carb and Other Grains

This recipe is incredibly versatile. You can easily adjust the filling to meet your dietary needs or simply use what you have on hand.

For a Low-Carb or Keto Version

To make a low-carb version of these stuffed bell peppers with ground beef, simply replace the one cup of cooked rice with one to one and a half cups of cauliflower rice. Add the raw cauliflower rice directly to the skillet with the tomato sauce and let it cook for a few minutes to soften before you stir in the cheese.

Other Grain Options

If you are not avoiding carbs but want to add more nutrients, feel free to swap the white rice. Cooked quinoa, farro, or brown rice are all excellent substitutes. They add extra fiber and a wonderfully chewy texture to the filling.

Pro Tips and Troubleshooting

Here are a few of my best tips and tricks I have learned from making this recipe countless times in my kitchen.

Pro Tips for Success

Don’t Skip the Beef Tenderizing. I cannot stress this enough. The baking soda and salt mixture is the secret to a perfectly tender and juicy ground beef filling. It is a small step that makes a huge difference.

Always Pre-Roast the Peppers. This step develops the natural sweetness of the bell peppers and ensures they are perfectly tender, not unpleasantly crunchy, in the final dish.

Pat Peppers Dry. To help prevent watery stuffed peppers, use a paper towel to gently pat the inside of the peppers dry after they come out of their initial roast. This removes excess moisture before you add the filling.

Use Sweeter Peppers. For the best flavor, always opt for red, yellow, or orange bell peppers. Their sweetness is a wonderful complement to the savory, cheesy filling.

Bloom Your Spices. When you add the chili powder, cumin, and oregano to the skillet with the beef, let them cook for about a minute. This brief moment in the hot oil wakes up their flavors and makes them more aromatic.

Common Mistakes to Avoid

Underbaking the Peppers. Make sure the peppers are truly fork-tender before serving. No one wants a crunchy, raw-tasting pepper.

Burning the Garlic. Add the garlic to the skillet after the onions have softened and cook it for only about a minute until fragrant. Burnt garlic will add a bitter taste to your entire dish.

Over-stuffing. Pack the filling into the pepper halves, but avoid mounding it too high. Over-stuffing can prevent the filling from heating through evenly in the center.

Skipping the Salt on the Peppers. Sprinkling a little salt directly onto the peppers before their first roast seasons them from the inside out, ensuring every part of the dish is well-flavored.

Serving and Storage

These stuffed peppers are a fantastic meal on their own, but a simple side can round them out beautifully. Proper storage also means you can enjoy them for days.

Serving Ideas

I love to serve these stuffed bell peppers with a side of fluffy cornbread to soak up any extra sauce. A simple green salad with a light vinaigrette also provides a fresh, crisp contrast. For a garnish, a dollop of sour cream or a sprinkle of fresh chopped parsley or cilantro adds a nice finishing touch.

Storage and Make-Ahead

This is a perfect make-ahead recipe.

To Refrigerate: Store cooked and cooled stuffed peppers in an airtight container in the refrigerator for up to four days. Reheat them in the microwave or in a 350°F oven until warmed through.

To Freeze: You can freeze the cooked and cooled stuffed peppers for up to three months. Place them in a freezer-safe, airtight container. To reheat from frozen, place them in a baking dish covered with foil and bake at 425°F for 15 to 20 minutes. Then, uncover them, top with a little fresh cheese if you like, and bake for another 5 to 10 minutes until hot and bubbly.

This recipe for stuffed bell peppers with ground beef is a true keeper. The super-savory filling, perfectly tender peppers, and overall reliability make it a standout. It is simple enough for any skill level, and the results are consistently delicious. I encourage you to try the recipe and even make it your own using some of the variations we discussed, perhaps even exploring other creamy stuffed bell pepper recipes.
