Air Fryer Stuffed Bell Peppers
Ingredients
Method
- Prep the peppers: Slice about 1/2 inch off the tops, remove seeds and membranes, and trim the bottoms if needed so they stand upright. Lightly brush the outsides with olive oil.
- Preheat the air fryer: Set it to 360°F (182°C) for 3–5 minutes so the basket is hot.
- Sauté aromatics: Heat the olive oil in a skillet over medium. Cook onion for 3–4 minutes until soft, then add garlic for 30 seconds until fragrant.
- Brown the meat: Add ground beef or turkey to the skillet. Season with salt, pepper, Italian seasoning, paprika, and red pepper flakes if using. Cook, breaking it up, until no longer pink.
- Add veggies and sauce: Stir in marinara, riced cauliflower, and spinach. Cook 2–3 minutes to meld flavors. Taste and adjust salt and pepper.
- Add cheese: Remove from heat. Stir in 1/2 cup mozzarella and the Parmesan until combined.
- Stuff the peppers: Spoon the filling into each pepper, packing it down slightly. Top with the remaining 1/4 cup mozzarella.
- Air fry: Arrange peppers upright in the basket (use a small piece of foil ring under a pepper if it wobbles). Cook at 360°F (182°C) for 10–14 minutes, until peppers are tender and cheese is melted and browned in spots.
- Finish and serve: Let rest 3–5 minutes. Garnish with chopped parsley or basil. Serve hot.
Storage Instructions
- Refrigerator: Store cooled stuffed peppers in an airtight container for up to 4 days.
- Freezer: Wrap each pepper tightly in plastic, then place in a freezer bag. Freeze up to 2 months. Thaw overnight in the fridge before reheating.
- Reheat: Air fryer at 320°F (160°C) for 6–8 minutes, or microwave in 60–90 second bursts until warmed through.
Add a sprinkle of water and cover loosely if microwaving to prevent drying.
Why This is Good for You
- Balanced macros: Protein from the meat, fiber from peppers and veggies, and moderate fat from cheese help keep you full.
- Lower in carbs: Riced cauliflower stands in for grains, keeping it low carb without losing texture.
- Micronutrient boost: Bell peppers bring vitamin C and antioxidants; spinach adds iron and folate.
- Better portion control: Each pepper is a tidy serving, making it easier to manage calories.
What Not to Do
- Don’t overfill with sauce: Too much liquid makes the filling watery and the peppers soggy.
- Don’t skip preheating: A hot basket helps the peppers soften faster and the cheese brown nicely.
- Don’t crowd the basket: Airflow matters. Cook in batches if needed for even cooking.
- Don’t use wet veggies: Squeeze excess moisture from frozen spinach and thawed cauliflower rice.
- Don’t under-season: Taste the filling before stuffing and adjust salt, pepper, and herbs.
Alternatives
- Protein swaps: Use Italian sausage (remove casings), ground chicken, or a 50/50 mix of beef and sausage. For vegetarian, try crumbled tempeh or a plant-based ground.
- Cheese options: Cheddar, pepper jack, or provolone change the vibe.
For dairy-free, use a meltable plant-based cheese or skip cheese and add extra herbs.
- Flavor profiles: Go Tex-Mex with chili powder, cumin, and a little salsa; Greek with oregano, lemon zest, and feta; or Cajun with blackening seasoning.
- Veggie add-ins: Finely chopped mushrooms, zucchini, or kale work well—just sauté to reduce moisture first.
- Kick of heat: Stir in minced jalapeño or a dash of hot sauce to the filling.
FAQ
Do I need to pre-cook the peppers?
No. The air fryer softens them quickly. If you like super tender peppers, you can air fry the empty shells for 4–5 minutes at 360°F before stuffing.
Can I make these without cheese?
Yes.
The filling is flavorful on its own. Add a tablespoon of olive oil or a spoonful of pesto to maintain richness, or top with dairy-free cheese.
How do I keep the peppers from tipping over?
Trim a thin slice off the base to create a flat surface, or form small rings of foil to cradle them in the basket so they stand upright.
What’s the best pepper color to use?
Any color works. Red, yellow, and orange are sweeter; green is more savory and slightly bitter.
Choose based on your flavor preference.
Can I use leftover cooked rice instead of cauliflower rice?
Yes, if you’re not strictly low carb. Use 1/2 to 3/4 cup cooked rice and reduce the marinara slightly to avoid excess moisture.
How do I avoid a dry filling?
Use a bit of sauce and don’t overcook the meat before mixing it with vegetables and cheese. The cheese and marinara help lock in moisture.
What if I don’t have an air fryer?
Bake in a 375°F (190°C) oven for 25–35 minutes in a baking dish, loosely covered with foil for the first 20 minutes, then uncover to brown the tops.
Can I prepare them ahead of time?
Yes.
Assemble up to 24 hours in advance, cover, and refrigerate. Air fry straight from the fridge, adding 2–3 extra minutes as needed.
How do I know when they’re done?
The peppers should be fork-tender, the cheese melted and golden in spots, and the filling hot throughout. An instant-read thermometer should read at least 165°F (74°C) in the center.
What sides go well with this?
Try a simple green salad, garlic-roasted broccoli, or sautéed zucchini.
For non–low carb eaters, serve with quinoa or crusty bread.
