Why Cook Fajita Veggies in the Air Fryer?
- Faster Cooking – No need to stand over a hot skillet. The air fryer does the job in minutes.
- Less Oil Needed – Enjoy crispy, caramelized veggies with minimal oil.
- Even Cooking – The circulating hot air ensures your veggies are cooked evenly.
- Very Versatile – Vary the veggies and seasoning to your taste.
Ingredients
- Bell Peppers: I like to use a mix of colored bell peppers for a vibrant touch and depth of flavors. Green is slightly bitter, while red and yellow are sweeter.
- Onion: I use red onions to add a mild sweetness.
- Oil: I use olive oil or avocado oil.
- Seasoning: I used garlic powder, cumin, paprika, salt, pepper, and oregano. You can change the seasoning based on your taste or use store-bought fajita or taco seasoning.
- Lime Juice: A squeeze of fresh lime at the end brightens up the dish.
How to Make Veggie Fajitas in the Air Fryer?
Preheat the Air Fryer to 380°F (190°C). In a large bowl, toss the sliced peppers and onions with oil and all the spices. Mix well to coat evenly.

Spread the veggies in a single layer in the air fryer basket.

Cook for 8-10 minutes, shaking halfway through. The peppers should be tender and lightly charred. You can also do this in multiple batches.

Once done, squeeze fresh lime juice over the top and garnish with cilantro if desired. Serve hot! We love them over warm tortillas with a protein topped with guacamole, sour cream, shredded cheese, and lettuce.

- Tofu or Paneer: A great protein option! Use extra firm tofu or paneer cut into strips.

Can I use Frozen Fajita Veggies?
Yes! If you’re using frozen fajita veggies, there’s no need to thaw them. Just add a minute or two to the cooking time. Keep in mind that frozen veggies may release more moisture, so they won’t be as crisp as fresh ones.
Pro-Tips
Cut veggies evenly: To ensure uniform cooking and the perfect tender-crisp texture.
Don’t overcrowd the basket: Cook in batches if needed for even cooking.
Meal Prep Friendly: Make in advance and store for easy meal assembly.
Use a fajita seasoning mix: If you prefer, you can skip the spices listed in the recipe and use a store-bought fajita seasoning mix.
