Ingredients and Substitutions
Crafting these delicious air fryer peppers and onions requires just a handful of simple, fresh ingredients. Here’s a detailed look at what you’ll need and how you can adapt the recipe to your pantry and preferences. The precise quantities are listed in the comprehensive recipe card at the very end of this article.
- Bell Peppers: You’ll need a total of 3 large bell peppers for this recipe. I typically opt for a colorful medley of red, orange, and yellow bell peppers. These varieties are naturally sweet and develop a wonderful caramelized flavor when air-fried. While green bell peppers can be used, be aware that they have a more bitter, less sweet flavor compared to their colorful counterparts, which might alter the overall taste profile of the dish. Feel free to use any combination you have on hand or prefer.
- Red Onion: Red onions are my go-to choice for this recipe, and for good reason. Their vibrant color is appealing, and when cooked, they become beautifully sweet and tender while still holding their shape and a pleasant texture. This sweetness complements the bell peppers perfectly. If red onions aren’t available, white or yellow onions can be substituted, but expect a slightly less sweet outcome in the final dish.
- Oil: A good quality oil helps the seasonings adhere to the vegetables and promotes even cooking and slight crisping in the air fryer. My preferred choices are extra virgin olive oil for its rich flavor or avocado oil for its higher smoke point and neutral taste. A small amount goes a long way in the air fryer!
- Salt and Pepper: These fundamental seasonings enhance the natural flavors of the vegetables. This recipe uses a moderate amount to start, allowing the inherent sweetness of the peppers and onions to shine. I always recommend tasting the cooked vegetables and adjusting the salt and pepper to your personal preference before serving. You might find you want a little more!
- Garlic Powder: Just a touch of garlic powder is added for a subtle aromatic depth. It’s not meant to overpower the dish but rather to provide a background note of savory flavor that rounds out the sweetness of the vegetables. If you prefer a more pronounced garlic flavor, you can certainly increase the amount slightly.
- Red Pepper Flakes: This ingredient is entirely optional but highly recommended if you enjoy a hint of heat. A dash of crushed red pepper flakes adds a lovely warmth and subtle kick that beautifully contrasts with the sweet vegetables. You can add them along with the other seasonings before cooking, or sprinkle them on after for a fresher, more vibrant spice.

Expert Tips for Perfect Air-Fried Peppers and Onions
Achieving perfectly cooked, flavorful air fryer peppers and onions is simple with a few insider tricks. Follow these key tips to ensure your vegetables come out delicious every time:
- Consistent Slicing is Crucial: Be sure to cut both the bell peppers and red onions into uniform 1/2-inch slices. This consistency is vital for even cooking. If your slices are too thick, they will take longer to cook and might remain firm. If they’re too thin, especially the onions, they can become overly soft, stringy, or even burn easily. Uniformity guarantees that all pieces reach the desired tenderness simultaneously.
- Understand Your Desired Texture: The recipe’s suggested cooking time will result in peppers that are just tender and onions that have started to caramelize on their edges, still retaining a slight bite. This texture is often preferred for dishes like fajitas or as a side. However, if you prefer a softer, more deeply caramelized texture, you can air fry them for an additional 2-4 minutes. Keep a close eye on them during this extra time, as air fryers can cook quickly, and vegetables can go from perfectly done to burnt in a blink.
- Account for Air Fryer Capacity: This recipe was developed and tested using a 5.8-quart air fryer. If your air fryer has a smaller capacity (e.g., 2.75-3.5 quarts), you might need to make two batches to avoid overcrowding the basket. Overcrowding significantly reduces airflow, leading to steamed rather than roasted vegetables. If you have a larger air fryer, you might be able to fit the entire batch, but still ensure there’s enough space for air circulation.
- Don’t Forget to Shake: Shaking the air fryer basket one to two times during cooking is not just a suggestion – it’s a critical step! This redistributes the peppers and onions, ensuring that all sides are exposed to the hot air, leading to even cooking and beautiful caramelization without dry spots or uneven browning.
- Preheat (Optional but Recommended): While many air fryer recipes don’t explicitly require preheating, I find that a preheated air fryer (set to 400°F/200°C for 3-5 minutes before adding vegetables) can help achieve a slightly crisper exterior more quickly, mimicking the effect of dropping food into a hot pan.
- Avoid Over-Oiling: The beauty of air frying is that it requires less oil. Use just enough to lightly coat the vegetables and help the seasonings adhere. Too much oil can lead to a greasy finish and prevent the natural sugars from caramelizing properly.
Recipe FAQs
Have questions about making, storing, or serving your air fryer peppers and onions? Here are answers to some frequently asked questions to help you get the most out of this versatile side dish!
The easiest and quickest way to reheat air fryer peppers and onions is in the microwave for 45-60 seconds, or until they are heated through. If you prefer a slightly crisper texture, you can reheat them in a skillet on the stove top over medium heat for a few minutes, stirring occasionally. Alternatively, you can use the air fryer again at 350°F (175°C) for 3-5 minutes. Whichever method you choose, be careful not to reheat them for too long, as they can become overly soft or even start to burn.
Yes, absolutely! Air-fried peppers and onions freeze very well and are fantastic to have on hand for quick additions to stir-fries, omelets, or soups. To freeze them, first allow the cooked vegetables to cool completely. Then, spread them out in a single layer on a baking sheet and place them in the freezer for about an hour or until solid. Once frozen, transfer the individual pieces to a freezer-safe bag or airtight container. They can be stored in the freezer for up to 3 months. Keep in mind that once thawed, their texture may be a little softer than when freshly cooked, but their flavor will remain delicious.
Leftover air fryer peppers and onions should be stored in an airtight container in the refrigerator. They will maintain their quality and flavor for up to 3-4 days. They’re excellent for adding to salads, wraps, or as a quick side for subsequent meals.
Yes, you can certainly customize this recipe by adding other quick-cooking vegetables! Mushrooms, zucchini, thinly sliced carrots, or even cherry tomatoes would be delicious additions. Just be sure to cut them to a similar size as the peppers and onions to ensure even cooking. Keep in mind that adding significantly more vegetables might require cooking in batches to avoid overcrowding the air fryer basket.
While the air fryer provides unique convenience and a specific texture, you can achieve similar results in a conventional oven. Spread the seasoned peppers and onions in a single layer on a baking sheet and roast at 400°F (200°C) for 20-25 minutes, flipping halfway through, or until tender and lightly caramelized. You can also sauté them in a large skillet over medium-high heat with a bit more oil until softened and browned, though this method is more hands-on.
Serving Suggestions
The beauty of air fryer peppers and onions lies in their incredible versatility! Here are just a few ideas to incorporate them into your meals:
- Fajitas & Tacos: They are the quintessential filling for chicken, beef, or vegetarian fajitas and tacos.
- Sandwiches & Wraps: Add them to grilled cheese, Philly cheesesteak sandwiches, or any wrap for an extra boost of flavor and nutrition.
- Eggs & Omelets: Fold them into your morning scrambled eggs, omelets, or frittatas for a hearty breakfast or brunch.
- Grain Bowls & Salads: Serve them warm over a bed of quinoa, rice, or your favorite greens for a satisfying and healthy meal.
- Burgers & Sausages: Top your grilled burgers, hot dogs, or Italian sausages with these caramelized vegetables.
- Pizza Topping: Sprinkle them over homemade or store-bought pizza for a vibrant and flavorful addition.
- Pasta Dishes: Toss them into pasta with a light sauce or as part of a roasted vegetable pasta salad.
- Side Dish: Simply serve them alongside grilled chicken, steak, fish, or any main course.

Description
Air Fryer Peppers and Onions are a quick and easy side dish made with sweet bell peppers, red onion and a few basic seasonings. They’re easy to prep, take just 10 minutes in the air fryer and make a delicious topping for fajitas and salads!
Ingredients
- 3 large bell peppers, cut lengthwise into 1/2-inch slices
- 2 small red onions (or 1 large), cut lengthwise into 1/2-inch slices
- 2 tablespoons olive oil
- 1/2 teaspoon fine sea salt
- 1/4 teaspoon garlic powder
- 1/4 teaspoon ground black pepper
- 1/8 teaspoon crushed red pepper flakes (optional)
Instructions
- Add all of the ingredients to a large bowl and toss until the peppers and onions are well coated.
- Transfer to the air fryer basket and air fry on 400F for 10-12 minutes, or until fork tender. (Shake the basket 1-2 times to ensure the peppers and onions cook evenly).
Notes
- I used red, orange and yellow bell peppers, but you can use whatever combination you have on hand. Just note that green peppers are not sweet like the other varieties.
- For even cooking, cut the peppers and onions into 1/2-inch slices. If you cut the onions thinner, they may end up paper thin once cooked.
- The peppers are air fried until just tender and the onions start to caramelize on the ends. Both will still be on the firm side, so if you prefer a softer texture, just air fry them for a few minutes longer.
- I used a 5.8 quart air fryer to make this recipe. If you have a smaller capacity air fryer, you will need to increase the cooking time by about 5 minutes, or cook in batches.
