Why Roast Red Peppers in an Air Fryer?
Roasting red peppers brings out their natural sweetness and adds a subtle smoky depth that transforms them from crunchy veggies into rich, velvety ingredients. Traditionally, this meant firing up the oven or using a gas stovetop flame—both effective but time-consuming and messy. Enter the air fryer: your new best friend for quick, hands-off roasting.
The air fryer’s rapid hot air circulation mimics the charring effect of an open flame or broiler, giving you perfectly blistered skins and tender flesh in under 20 minutes. Plus, it uses far less energy than heating a full-sized oven. Whether you’re meal prepping, cooking for one, or just want dinner ready fast, roasting red peppers in an air fryer is a game-changer.
What You’ll Need
You don’t need fancy equipment or hard-to-find ingredients. Here’s what to grab:
Ingredients
- 2–4 whole red bell peppers (fresh, firm, and glossy)
- 1 teaspoon olive oil (optional, for easier peeling)
- Pinch of salt (optional)
Equipment
- Air fryer (basket or tray style)
- Tongs or heat-resistant gloves
- Knife and cutting board
- Bowl of ice water (for steaming, optional but helpful)
- Paper towel or clean kitchen towel
That’s it! No special trays or foil needed—just your trusty air fryer and a few basics from your kitchen.
Step-by-Step Instructions
Roasting red peppers in an air fryer is surprisingly simple. Follow these steps for flawless results every time.
1. Prep the Peppers
Start by washing the red peppers thoroughly under cool water. Pat them dry with a clean towel. You can leave them whole—no need to cut or core them beforehand. In fact, keeping them intact helps prevent moisture loss and ensures even roasting.
2. Optional: Lightly Oil the Skin
If you’d like to make peeling easier later, lightly brush each pepper with a tiny amount of olive oil. This isn’t necessary, but it helps the skin blister more evenly and release from the flesh. A little goes a long way—too much oil can cause splattering in the air fryer.
3. Air Fry Until Charred
Place the whole peppers in the air fryer basket, leaving space between them so hot air can circulate. Set the temperature to 400°F (200°C) and cook for 15–20 minutes. Flip them halfway through using tongs to ensure all sides get evenly charred.
You’ll know they’re done when the skin is blistered, blackened in spots, and slightly puffed. The peppers should feel soft when gently squeezed. Don’t worry about the black bits—that’s flavor!
4. Steam and Peel
Once roasted, immediately transfer the peppers to a bowl and cover with plastic wrap or a lid. Let them steam for 10–15 minutes. This loosens the skin, making it easy to peel off by hand or with a knife.
After steaming, use your fingers or a small knife to remove the skin, stem, and seeds. Rinse under cold water if needed to remove any remaining blackened bits. Now you have perfectly roasted red peppers ready to use!
Tips for Perfect Results
A few small tweaks can make a big difference in your air-fried red peppers.
Don’t Overcrowd the Basket
Give each pepper room to breathe. Overcrowding traps steam and prevents proper charring. If you’re roasting more than your air fryer can handle at once, cook in batches.
Adjust Time Based on Size
Larger peppers may need up to 25 minutes, while smaller ones could be done in 12. Keep an eye on them after the 15-minute mark to avoid overcooking.
Use a Trivet for Even Cooking
If your air fryer has a trivet or rack, place the peppers on it instead of directly in the basket. This elevates them and allows heat to reach all sides more evenly.
Save the Juice!
When you cut open the peppers, you’ll notice some flavorful liquid inside. Don’t toss it! This concentrated pepper essence is perfect for adding to sauces, soups, or salad dressings.
How to Use Roasted Red Peppers
Once you’ve mastered the technique, the culinary possibilities are endless. Here are some delicious ways to use your air-fried roasted red peppers:
- In pasta dishes: Toss with olive oil, garlic, and pasta for a quick weeknight meal.
- On sandwiches or wraps: Add layers of flavor to turkey, hummus, or veggie wraps.
- As a pizza topping: Pair with mozzarella, basil, and a drizzle of balsamic glaze.
- In dips and spreads: Blend into hummus, tzatziki, or a creamy red pepper dip.
- Chopped in salads: Brighten up grain bowls or green salads with their sweet, smoky notes.
- Preserved in oil: Store in a jar with olive oil and herbs for a pantry staple that lasts weeks.
They’re also fantastic alongside proteins like grilled chicken or fish. Try pairing them with our Air Fry Chicken Thighs for a complete, flavorful meal.
Storage and Reheating Tips
Roasted red peppers keep well, so feel free to make a big batch!
Refrigeration
Store peeled peppers in an airtight container with a little olive oil to keep them moist. They’ll stay fresh for up to 5 days in the fridge.
Freezing
For longer storage, freeze them in portions. Lay slices flat on a baking sheet, freeze until solid, then transfer to a freezer bag. They’ll keep for up to 6 months. Thaw in the fridge before using.
Reheating
To reheat, simply warm in a skillet over low heat or pop in the air fryer for 2–3 minutes at 350°F. Avoid microwaving if possible—it can make them soggy.
Common Mistakes to Avoid
Even simple recipes can go sideways if you’re not careful. Watch out for these pitfalls:
- Skipping the steam step: Peeling will be frustrating and messy without it.
- Using green or unripe peppers: They lack the sweetness and soften less during roasting. Stick to bright red, fully ripe peppers.
- Setting the temperature too low: Below 375°F, the peppers won’t char properly. Always use 400°F for best results.
- Peeling too soon: Let them steam fully—rushing this step tears the flesh.

Why This Method Beats the Oven
While oven-roasting red peppers works, the air fryer offers clear advantages:
- Speed: No preheating required—just toss in and go.
- Energy efficiency: Uses up to 70% less energy than a conventional oven.
- Less mess: No oil dripping onto oven racks or baking sheets.
- Better control: Easier to monitor and flip without opening a hot oven door.
And unlike stovetop flame-roasting, there’s no risk of burning yourself or dealing with smoke alarms. It’s hands-down the safest, most convenient method for home cooks.

Frequently Asked Questions
Can I roast red peppers in an air fryer without oil?
Yes! While a light brush of oil helps with even charring and peeling, it’s not required. The air fryer’s dry heat will still blister the skin effectively.
How do I know when the peppers are fully roasted?
The skin should be deeply blistered, wrinkled, and partially blackened. The peppers will feel soft when gently pressed with tongs.
Can I roast other colored peppers the same way?
Absolutely. Yellow, orange, and even green bell peppers can be roasted using this method, though green peppers may take slightly longer and retain more bitterness.
Do I have to peel the peppers?
Peeling is recommended for most recipes, as the charred skin can be tough and bitter. However, if blending into a sauce or soup, you can leave it on—just strain if desired.
Can I freeze roasted red peppers?
Yes! Freeze them in airtight containers or freezer bags for up to 6 months. Thaw in the refrigerator before using.
What if my air fryer doesn’t go up to 400°F?
Cook at the highest setting (usually 390°F) and add 2–3 minutes to the cooking time. The key is achieving a good char, so don’t rush it.
