Ingredients for Making Air Fryer Steak Fajitas
- Oil: I used avocado oil, but you can use your favorite high-heat oil. Olive oil is fine, but I don’t recommend extra-virgin olive oil.
- Lime juice: Fresh is best, but you can use bottled in a pinch.
- Garlic: I used fresh garlic, but you could also use garlic powder.
- Fajita seasoning: You can find this in the spice aisle of your grocery store. Or, you can make homemade fajita seasoning with chili powder, paprika, cumin, garlic powder, cayenne pepper, onion powder, and salt. If trying to be low-carb or keto, make sure you choose a fajita seasoning mix that is gluten-free and doesn’t have sugar.
- Steak: I used top sirloin steak, but you could also use flank steak.
- Bell peppers: I used red bell pepper and yellow bell pepper, but feel free to use your favorite color or mix it up! Green bell pepper will have a stronger flavor, so keep that in mind if you are serving small children.
- Onion: I used a large white onion, but you could also use yellow or red onion.
- For Serving: Serve your fajitas with flour tortillas, shredded lettuce, salsa, sour cream, avocado, guacamole, cheese, and cilantro.
Tips & Tricks
- I like to slice my steak against the grain for fajitas. This helps it to be more tender when cooked.
- If you don't have a large air fryer, you may need to cook your fajitas in batches.
- Don't overcrowd the air fryer basket. This will cause the food to steam instead of air fry, and it won't get that nice crispy texture.
- Though peppers and onions are traditionally used for fajitas, feel free to play with the veggies. Mushrooms and zucchini are excellent additions.
Frequently Asked Questions
I like to use top sirloin steak for my air fajitas. It's a relatively lean cut of beef that is still full of flavor. You could also use flank steak or skirt steak to make air fryer fajitas with steak.
No, you don't need to marinate the steak before cooking. However, if you have the time, I recommend letting it sit in the spice mixture for at least 1 hour. This will help to infuse the flavors into the meat.

Yes, you can use frozen peppers and onions. Just be sure to thaw them thoroughly before adding them to the air fryer basket, or expect the texture to be a little softer.

How to Cook Beef Fajitas in an Air Fryer
First, start by making the marinade. In a small bowl or blender, combine the avocado oil, lime juice, garlic, and fajita seasoning.
Next, cut the steak into thin strips against the grain.
Place the steak in one zip-top bag or shallow dish and the vegetables in another. (You could also use mixing bowls if desired.) Pour half of the marinade over the steak and the other half over the vegetables. Marinate for at least 30 minutes, up to 4 hours.
When ready to cook, line your air fryer with an air fryer liner. This will help to prevent sticking and make clean-up a breeze.
Remove the vegetables from the marinade and drain. Set your air fryer to 400 degrees Fahrenheit and place the vegetables in the air fryer basket.
Cook for 13 minutes. You can cook longer if you want more tender veggies.
Remove from the air fryer.
Remove the steak from the marinade and drain. Place the steak strips in the air fryer basket and cook for 4-6 minutes per side until cooked to your desired level of doneness. (Use a meat thermometer for the perfect cook every time! The cooking time will vary slightly depending on your air fryer and the thickness of the meat.
Serve your fajitas with warm tortillas, shredded lettuce, salsa, pico de gallo, sour cream, avocado, guacamole, cheese, and fresh cilantro. Corn or refried beans make an excellent side for this tex-mex dish.
