Ingredients You'll Need
This Air Fryer Peppers and Onions Recipe shines because of its straightforward, wholesome ingredients. Each one plays a crucial part—from the sweetness of the bell peppers and the sharpness of the red onion to the fragrant Italian seasoning that ties it all together with a Mediterranean flair.
- 2 bell peppers: Slicing them lengthwise into ½-inch strips ensures even cooking and a perfect tender bite.
- 1 red onion: Also sliced lengthwise matchsticks to complement the peppers and caramelize beautifully in the air fryer.
- 1 tablespoon olive oil: This coats the vegetables to help golden edges develop, adding richness and helping seasonings stick.
- 1 teaspoon garlic powder: A convenient way to infuse a lovely garlic aroma without overpowering the natural sweetness of the veggies.
- 1 teaspoon Italian seasoning: A charming blend that adds herbaceous depth and Mediterranean character.
- ¼ teaspoon salt: Just enough to pull out the natural flavors without making the dish salty.
- Black pepper (to taste): For that essential touch of spice and a little extra warmth.
How to Make Air Fryer Peppers and Onions Recipe
Step 1: Preheat the Air Fryer
Start by preheating your air fryer to 375 degrees Fahrenheit. Preheating ensures a consistent, hot environment right from the start, helping the vegetables cook evenly and develop that signature caramelized texture we’re aiming for.
Step 2: Toss the Vegetables with Oil and Seasonings
In a large mixing bowl, combine your sliced bell peppers and red onions. Drizzle with olive oil, then sprinkle garlic powder, Italian seasoning, salt, and black pepper over top. Toss everything together until the vegetables are coated evenly, setting the stage for incredible flavor and crispy edges once cooked.
Step 3: Arrange in the Air Fryer Basket
Carefully place the seasoned vegetables in the air fryer basket in a single layer. Avoid overcrowding or overlapping too much, as good air circulation is key to achieving that tender yet slightly crisp texture with beautifully caramelized edges.
Step 4: Cook Until Tender and Caramelized
Air fry the vegetables for 12 to 16 minutes. After about 8 minutes, shake the basket gently to turn the peppers and onions, allowing all sides to brown evenly. Check frequently after shaking and continue cooking in short intervals to ensure they become fork-tender without burning. You'll know they’re done when the edges begin to caramelize with that irresistible golden brown color.
Step 5: Serve or Store
Once cooked, you can serve the peppers and onions immediately for the best texture and flavor. Alternatively, allow them to cool to room temperature before transferring to an airtight container if you're planning to store them for later use.

Make Ahead and Storage
Storing Leftovers
Store any leftover Air Fryer Peppers and Onions Recipe in an airtight container in the refrigerator for up to 4 days. Keeping them covered well will preserve their moisture and flavors without allowing them to dry out.
Freezing
You can freeze these cooked peppers and onions by placing them in a freezer-safe container or bag. For best quality, consume within 2 months. When you're ready to use, thaw overnight in the refrigerator for easy reheating.
Reheating
To refresh your leftovers, reheat in the air fryer at 350 degrees Fahrenheit for about 3 to 5 minutes. This helps to revive the crisp edges. Alternatively, warm them gently on the stovetop or in the microwave, though they might lose some of their initial crispness.
FAQs
Can I use other types of peppers in this Air Fryer Peppers and Onions Recipe?
Absolutely! Feel free to experiment with different bell pepper colors or even spicy varieties like poblano or banana peppers for a flavor twist—but keep an eye on cooking times since some peppers might cook faster or slower.
Is it necessary to peel the onion?
Yes, peeling your onion is important to remove the papery outer skin, which isn’t edible and would not cook well. Once peeled, slicing lengthwise ensures even cooking with the peppers.
Can I make this recipe vegan or allergen-free?
This recipe is naturally vegan and free of common allergens. Just make sure to use a neutral oil if you have olive oil sensitivities, and check your seasoning blends for any added allergens.
What if I don’t have Italian seasoning—can I substitute?
Definitely! Use a combination of dried oregano, basil, thyme, and rosemary if you have these on hand. The goal is to create a balance of herbs that complement the sweetness of the peppers and onions.
How do I know when the peppers and onions are cooked perfectly?
You want the vegetables to be fork-tender and the edges lightly caramelized. They should be soft but still hold their shape well, with a hint of golden browning that brings out a rich, sweet depth of flavor.
