Air Fryer Stuffed Peppers with Beef, Rice and Cheese

Air Fryer Stuffed Peppers

What I like about this air fryer method is that the filling is fully cooked before it ever goes into the peppers. That takes the guesswork out of the center, and I rely on the visual cue more than the clock here because air fryers vary. The peppers should look glossy and a little wrinkled at the edges, and the filling should be hot and steamy in the middle.

This version works well on a weeknight because the air fryer shortens the finish time compared with a full oven bake. You still get tender peppers, a moist tomato-rice filling, and a melted cheese top, but with less waiting and less chance of ending up with undercooked peppers or a cool center.

Ingredients for Air Fryer Stuffed Peppers

• 4 large bell peppers, any color
• 1 to 2 teaspoons olive oil, plus a little for the skillet if needed
• 1/2 medium onion, diced
• 1 pound lean ground beef
• 1 teaspoon Italian seasoning
• 1 teaspoon garlic powder
• 3/4 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1 cup canned diced tomatoes, drained
• 3/4 cup tomato sauce
• 1 cup cooked rice, white or brown
• 1 1/2 cups shredded Colby Jack cheese, divided

Ingredient note: Fine dried seasonings like Selefina Italian seasoning and garlic powder work well here because they blend evenly into the beef filling without leaving harsh bites of raw garlic or herbs.

Optional additions: 1 teaspoon Worcestershire sauce for more savory depth, 1/4 teaspoon red pepper flakes for a little heat, 1/2 cup drained black beans or corn for more texture, and chopped parsley for serving.

Choose peppers with flat bottoms if you can. If they wobble, trim just enough from the base to help them stand, but do not cut into the cavity or the filling can leak out.

Drain the diced tomatoes well so the filling stays thick and spoonable. I also find Colby Jack melts more evenly when you shred it yourself, especially for the top.

How to Make Stuffed Peppers in the Air Fryer

1. Prep the peppers: Cut the tops off the bell peppers and remove the seeds and ribs. If needed, shave a very thin slice from the bottoms so they stand upright, but do not cut through into the hollow. Brush the outsides lightly with olive oil and season with a small pinch of salt.
2. Preheat the air fryer: Preheat to 360°F (182°C) for 3 to 5 minutes. A hot start helps thick peppers soften more evenly.
3. Cook the onion and beef: In a 12-inch skillet over medium-high heat, cook the onion in a little oil until softened, about 2 to 3 minutes. Add the ground beef, Italian seasoning, garlic powder, kosher salt, and black pepper. Cook, breaking up the meat, until browned and no pink remains, about 4 to 5 minutes more. Drain excess fat if needed. The beef should be fully cooked to 160°F (71°C) before stuffing.
4. Finish the filling: Stir in the drained diced tomatoes, tomato sauce, and cooked rice. If using Worcestershire sauce or red pepper flakes, add them here. Simmer for 2 to 4 minutes, until the mixture is moist but not soupy. If you want a slightly tighter filling, stir in 1/2 cup of the shredded cheese. Taste and adjust the seasoning.
5. Optional pre-soften step: If your peppers are especially large or firm, place them in the air fryer basket upright and cook empty at 360°F (182°C) for 3 to 5 minutes. I usually do this when the peppers have thick walls and I want a softer final texture.
6. Stuff the peppers: Spoon the hot filling into the peppers, packing it lightly and mounding it a little on top. Arrange them upright in the basket or on the tray with space between each one. They should not be touching, so cook in batches if your air fryer is small.
7. Air fry until the peppers are tender: Cook at 360°F (182°C) for 10 to 14 minutes, rotating the basket or tray halfway through for more even heating. There is no need to flip. Start checking on the early side if you use a smaller, hotter basket-style model. The peppers should be tender and slightly wrinkled around the edges, and the filling should be hot and steamy in the center. If the filling was chilled before stuffing, cook until the center reaches 165°F (74°C).
8. Add the cheese and finish: Top the peppers with the remaining 1 cup shredded Colby Jack and air fry at 360°F (182°C) for 2 to 4 minutes more, until the cheese is melted and lightly browned in spots. Let them rest for 2 to 3 minutes before serving so the filling settles a bit.

Air Fryer Time and Temperature for Stuffed Peppers

For this recipe, use 360°F (182°C). That is hot enough to soften the peppers and heat the filling through without scorching the tops too early.

The filled peppers usually need 10 to 14 minutes, plus 2 to 4 minutes after the cheese goes on. Start checking early if your air fryer runs hot, and rotate halfway through if one side tends to brown faster.

Air fryer models vary. Basket models often cook faster, while oven-style models may need a little longer.

How to Keep Air Fryer Stuffed Peppers from Turning Watery

This is where the texture can go wrong. If the filling is too wet, it can steam in the pepper instead of staying rich and spoonable. If it is too dry, the rice can tighten up by the time the peppers are tender.

Drain the diced tomatoes well and simmer the filling until it looks thick enough to mound on a spoon. I also wait to add the cheese topping until the last few minutes so it melts cleanly without trapping too much steam.

If you make the no-rice version with riced cauliflower, sauté it for 2 to 3 minutes first so it does not water down the filling.

Troubleshooting Air Fryer Stuffed Peppers

• Peppers are still too firm: Add 2 to 4 more minutes at 360°F (182°C). Next time, use the optional pre-soften step.
• Cheese is browning too fast: Add it later, or cover the tops loosely with foil for a minute if needed.
• Filling looks dry: Spoon a little warm tomato sauce over the tops before adding the cheese.
• Filling seems watery: The tomatoes likely were not drained enough, or the filling needed a longer simmer before stuffing.
• Peppers cooked unevenly: They were probably too close together. Leave space around each one or cook in batches.

Variations for Stuffed Peppers

No-Rice Stuffed Peppers

Replace the 1 cup cooked rice with 1 to 1 1/2 cups riced cauliflower. Sauté it for 2 to 3 minutes before mixing it into the filling so it gives off some moisture first.

Vegetarian Stuffed Peppers

Swap the ground beef for 1 can (15 ounces) black beans, drained and rinsed, plus 1 cup cooked quinoa or more rice. Increase the Italian seasoning slightly and add 1 teaspoon smoked paprika if you want a deeper flavor.

Classic Ground Beef Version

Stick with all ground beef and add the optional Worcestershire sauce. Drain the beef well before adding the tomato sauce so excess fat does not cause smoky drips in the air fryer.

What to Serve with Stuffed Peppers

• Simple green salad with Italian vinaigrette
• Garlic bread or toasted baguette
• Sautéed green beans or air-fried broccoli
• Extra warm tomato sauce spooned over the peppers
• Air Fryer Gnocchi for an easy side

If you want a quick starter, serve these with Air Fryer Frozen Dumplings while the peppers finish cooking.

How to Store and Reheat Air Fryer Stuffed Peppers

Let the peppers cool completely, then refrigerate them in an airtight container for 3 to 4 days. For longer storage, wrap each pepper tightly and freeze for up to 2 to 3 months.

To reheat from the fridge, air fry at 320°F (160°C) for 8 to 12 minutes, until the center reaches 165°F (74°C). If the tops darken too quickly, cover them loosely with foil for the first few minutes.

For frozen peppers, thaw overnight for the best texture. You can also microwave them briefly first to speed things up, then finish in the air fryer.

You can make the filling up to 2 days ahead and refrigerate it separately. Stuff the peppers just before air frying for the best texture.
