Air Fryer Stuffed Bell Peppers with Ground Beef

Air fryer stuffed bell peppers with ground beef are a fast, cheesy dinner. You fill sweet bell peppers with beef, rice, and melted cheese. The air fryer cooks them much faster than an oven. This dish is great for busy weeknights. It’s also a smart way to use up leftover rice.

The first time I made these, I skipped a key step. I did not pre-cook the peppers first. They came out crunchy and raw in the middle. The filling was hot, but the pepper was not. Now I always give the peppers a head start in the air fryer. That one change fixed the whole recipe. I have not skipped it since.

This version uses ground beef, but it’s easy to switch things up. You can use ground turkey instead. You can add new spices too. You can even skip the rice. I’ve made this dish more than a dozen times for my own family. This is the method that works every time. It’s simple enough for a weeknight, but tasty enough for guests. Baking peppers in the oven usually takes close to an hour, so the air fryer saves real time on a busy night.

Recipe Quick Facts

• Prep Time: 15 minutes.
• Cook Time: 27 minutes.
• Total Time: 42 minutes.
• Servings: 4 peppers.
• Difficulty: Easy.

Before You Get Started

• Pick medium or large peppers. Small peppers hold less food. They also tip over more in the basket.
• Choose your pepper color with taste in mind. Red, yellow, and orange peppers taste sweeter. Green peppers taste more bitter.
• Use beef that is not too lean. An 85/15 blend keeps the filling moist. I tried a leaner blend once. The filling turned dry and crumbly.
• Cook your rice ahead of time. Cold, leftover rice works best here. It holds its shape. It does not turn mushy.
• Trim wobbly peppers. Slice a thin piece off the bottom. This helps them stand up straight in the basket.
• Do not skip the first air fry. I learned this the hard way on my first try. Raw peppers stay crunchy even after the second cook.

Ingredients

• 4 medium or large bell peppers, any color.
• 1 pound ground beef, 85/15 blend.
• 1 ¼ cups shredded Colby Jack cheese, divided.
• 200 grams diced yellow onion, about 1 medium onion.
• 3 cloves garlic, minced.
• 1 tablespoon of olive oil.
• 1 teaspoon Italian herb blend.
• ¾ teaspoon salt.
• ¼ teaspoon black pepper.
• ¼ teaspoon red pepper flakes, optional.
• 1 can diced tomatoes, 15 ounces.
• 1 can tomato sauce, 8 ounces.
• 2 cups of cooked white rice.

Instructions

Step 1: Prep and Pre-Cook the Peppers

Cut the top off each bell pepper. Use a spoon to scoop out the seeds and white core. If a pepper wobbles, trim a thin slice off the bottom. (I use a paring knife for this part, since it makes a cleaner cut around the stem.)

Set the peppers upright in your air fryer basket. Cook at 380°F for 10 minutes. They should feel soft, not floppy. Drain off any liquid that pools inside. Do this before you fill them. This step matters more than it seems. Wet peppers make the whole filling soggy.

Step 2: Cook the Onion

While the peppers cook, heat olive oil in a large pan. Use medium-high heat. Once the oil looks hot and thin, add the diced onion.

Cook the onion for about 5 minutes. Stir it now and then. It’s ready once it turns soft and clear. In my kitchen, I add a splash of water if the onion browns too fast. The steam softens it. It does not burn.

Step 3: Brown the Beef

Take the onion out of the pan. Set it aside. Add the ground beef and garlic to the same pan.

Break up the beef with a spatula. Stir in the Italian herb blend. Cook it on medium-high heat for about 4 minutes. It’s done once it turns fully brown with no pink left. Put the onion back in the pan. Stir in the salt, black pepper, and red pepper flakes if you like heat.

Step 4: Simmer the Sauce

Add the diced tomatoes and tomato sauce to the pan. Bring it to a boil. Turn the heat down. Let it simmer for about 5 minutes. Stir it now and then.

The sauce is ready once it looks thick. Drag a spoon across the pan. It should leave a short trail. In my testing, this one step matters most. It keeps the filling from turning watery once it’s inside the peppers.

Step 5: Add Rice and Cheese

Take the pan off the heat. Let it cool for one minute. Stir in the cooked rice. Add 1 cup of the shredded cheese. Mix until the cheese melts into the filling.

Step 6: Stuff and Air Fry

Spoon the filling into each pepper. Fill them almost to the top, about 1 cup per pepper. Pack it in gently with the back of a spoon. Top each pepper with the last ¼ cup of cheese.

Place the stuffed peppers back in the air fryer. Cook at 380°F for 2 minutes. The cheese on top should look melted. It should just start to turn gold. Let the peppers sit in the basket for one minute before you take them out, since the bottoms stay very hot.

How To Make Air Fryer Stuffed Peppers (Quick Reference)

1. Hollow out 4 peppers. Air fry at 380°F for 10 minutes.
2. Cook diced onion in olive oil for 5 minutes.
3. Brown ground beef with garlic and herbs for 4 minutes.
4. Add diced tomatoes and tomato sauce. Simmer for 5 minutes until thick.
5. Off the heat, stir in cooked rice and 1 cup of cheese.
6. Stuff the peppers. Top with the rest of the cheese.
7. Air fry at 380°F for 2 minutes until the cheese melts.

Tips for Best Results

• Do not crowd your air fryer basket. Peppers need room for air to move. Cook in two batches if your basket is small.
• Shred your own cheese if you can. I found bagged cheese has a coating on it. That coating keeps it from melting smoothly into the filling.
• Let the peppers rest for 2 minutes. They come out very hot. A short rest makes them easier to eat.
• Taste the filling before you stuff the peppers. You can still fix the salt now. You cannot fix it once the peppers are cooked.
• Make extra filling on purpose. It keeps well on its own. Use it to top nachos. Stir it into pasta later in the week.

Ingredient Substitutions

Original Ingredient	Substitute	Effect on Taste and Texture
Ground beef, 85/15	Ground turkey thigh	Milder taste. Stay moist if you skip lean turkey breast.
White rice	Cauliflower rice	Lower carb. Filling turns a bit wetter and less starchy.
Colby Jack cheese	Sharp cheddar	Sharper, tangier bite. Melts about the same.
Italian herb blend	Curry powder	Warmer taste. Pairs well with raisins.
Diced tomatoes and sauce	Salsa, 15 ounces	Adds mild heat. Filling turns a bit chunkier.

Storage & Reheating

Store leftover peppers in a sealed container in the fridge. They keep well for up to 4 days. To reheat, air fry them at 350°F for 5 to 6 minutes. You can also warm them in the microwave. Use 60-second bursts and check often.

To freeze, wrap each cooled pepper in plastic wrap. Place the wrapped peppers in a freezer bag. They keep for up to 3 months. Thaw them in the fridge overnight. Reheat them the next day using the steps above. I don’t recommend microwaving a pepper straight from frozen, since the outside can turn mushy before the center heats through. A slow thaw in the fridge keeps the texture much closer to fresh.

FAQs

Do you need to pre-cook peppers before air frying them stuffed? 

Yes. Raw peppers stay firm and a bit crunchy, even after a short second. Cooking them empty for 10 minutes at 380°F softens them enough to finish well once stuffed.

Can I make stuffed peppers ahead of time?

Yes. You can prep the filling and hollow the peppers up to 2 days ahead. Store each part in the fridge, then stuff and air fry them right before you serve.

What temperature do you air fry stuffed peppers at? 

Air fry stuffed peppers at 380°F. Cook the empty peppers for 10 minutes first. Cook them again for 2 minutes after stuffing, until the cheese on top melts. This two-stage method keeps the pepper soft and the filling hot.

Can I use raw rice instead of cooked rice in the filling? 

No. Raw rice needs time and liquid to cook that this recipe does not allow. Always use rice that is already fully cooked before you add it to the beef.

Why did my stuffed peppers turn out watery? 

This usually happens when you skip draining the peppers, or the sauce does not simmer long enough. Drain the peppers well. Simmer the sauce until a spoon leaves a trail through it.
