Air fryer steak fajitas are spicy, satisfying, and a healthy way to enjoy this Mexican classic! Easily prepped ahead of time and simple to make, this is wonderful as a taco night dinner.
There's nothing quite like air fryer steak fajitas. Succulent strips of steak seasoned with warming spices, nestled in a tortilla with crunchy peppers and onions make for the perfect mouthful. And no messy oil drips to clean up!
If you haven't tried air fryer fajitas, you're missing out. Unlike fajitas made on the stovetop, you don't need much oil, which means you can taste all the flavors in the beautifully seasoned steak and veggies.
Steak fajitas in the air fryer are exceptional because the air fryer passes hot air all around the meat to cook it, which means it cooks evenly and doesn't lose any moisture. As a result, your steak will be juicy and tender every time.

- Steak. The meat is the most important ingredient for these steak fajitas in air fryer, so be sure to choose good quality flank steak or top sirloin. When preparing your steak, slice it into strips, and make sure you cut against the grain - this breaks up the muscle fibers and makes the meat more tender.
- Olive oil. Neutral tasting and high in vitamin E and antioxidants, olive oil is excellent for cooking.
- Fajita seasoning. You can buy pre-made fajita seasoning in most grocery stores or make your own. Check out my air fryer chicken fajitas recipe for a delicious homemade fajita seasoning in just a few minutes. Alternatively, taco seasoning works well.
- Red and green bell peppers, thinly sliced.
- Tortillas. Any brand of tortilla is fine - be sure to warm them up!
- Fajita toppings. Toppings are your opportunity to get creative. Load up your fajitas with salsa, guacamole, cheese, soured cream, refried beans, and cheese - as much as you can fit in there!

How long to cook beef fajitas in an air fryer
It takes around 17 minutes at 400°F to cook beef fajita air fryer, depending on how thick your steak slices are, your air fryer, and how you like your steak.
The easiest way to tell when your steak is done is by checking the texture if you don't have an instant meat thermometer:
- The medium-rare steak will feel tender and still slightly soft and fleshy - similar to your cheek.
- Medium steak is firm but still tender - like your chin.
- Medium-well steak is fleshy but firm - comparable to your forehead.
What to serve with steak fajitas
It's the toppings that make these air fryer beef fajitas!
Try serving them with creamy guacamole (you can make this yourself by mashing avocado, lemon juice, minced red onion, salt, and pepper), spicy black bean and corn salsa, sour cream, cotija cheese, refried beans, and instant pot rice.
How to store beef fajitas
Leftover air fryer fajita steak is terrific for a quick and easy lunch - I like to make more than I need so that I can look forward to it the next day!
To store your leftovers, seal them in an airtight container or Ziptop bag and put them in the fridge or freezer within 2 hours of cooking.
Cooked beef is safe to keep in the fridge for 3 to 4 days and in the freezer for 2 to 3 months.
How to reheat steak fajitas in the air fryer
Air fryer steak fajitas are a great make-ahead meal, and they're easy to reheat!
- In the air fryer, begin by preheating to 350°F, and then put the leftover air fryer fajita steak in. Heat for 3 to 5 minutes if heating from chilled and 13-15 minutes from frozen. Make sure you flip halfway through.
- Heat a pan or skillet to medium-high heat on the stovetop, and then add the steak—heat for a couple of minutes on each side. If the fajitas are frozen, you will need to defrost them first.
- In the oven, preheat to 250°F. Wrap your leftover fajita steak in foil, and then place it on a baking tray. Once the oven has reached temperature, switch it off and put the tray with the beef inside. Allow to heat for about 20 minutes.
Absolutely! Fajitas in the air fryer are delicious because heating the meat and vegetables with hot air means that they get a lovely crunch on the outside while remaining juicy and tender in the middle.
When making steak fajitas air fryer, use either flank steak or top sirloin. These steaks are boneless, so they're easier to prepare, as well as being tender and flavorful.
The most important thing to remember when cutting your steak is always to slice it against the grain. Slicing against the grain cuts the muscle fibers, which means your meat will be more tender, and your air fryer steak fajitas will be tender and delicious.
Air fryer fajitas steak only has a few ingredients, so it's a great meal to make if you don't want to do a massive shop! You will need:
Steak (flank or top sirloin)
Red and green bell peppers
Your choice of toppings (guacamole, refried beans, rice, cheese, and salsa all work well)
To season the meat for fajita steak in an air fryer, add it to a large bowl or Ziploc bag along with olive oil and fajita seasoning, and turn to coat.
Then, leave it in the fridge for at least 30 minutes and up to 8 hours. Then you're ready to start cooking!
Can you freeze cooked steak fajitas?
You can freeze the cooked air fry fajita steak with no problem, but I wouldn't recommend freezing the vegetables, tortillas, or toppings.
To freeze leftover fajita steak, seal it in an airtight container or Ziploc bag and then move it to the freezer within 2 hours of cooking (this prevents bacteria growth at room temperature). You can safely store it in the freezer for 2-3 months.
When you're ready to eat it, just put it straight in the air fryer to heat it - no need to defrost.
