Why You’ll Love Air Fryer Steak Fajitas

This recipe brings out the best in flank steak and veggies, thanks to a flavorful fajita seasoning and the magic of air frying. The steak comes out tender with a slightly crispy exterior, while the peppers and onions get perfectly caramelized. Whether served in warm tortillas or on a salad, these steak fajitas make a fresh and filling meal that’s perfect for busy weeknights or weekend get-togethers.

Tips for Perfectly Tender Steak

The key to making the best steak fajitas lies in how you cut and marinate the meat. Since flank steak can be a bit tough, follow these simple steps to ensure it turns out tender:

Marinate the Steak: Let the steak sit in a marinade made from fajita seasoning, olive oil, and lime juice for at least 30 minutes (up to 24 hours for deeper flavor).
Slice Across the Grain: When ready to cook, slice the steak against the grain. This means cutting perpendicular to the muscle fibers, which breaks them down and makes the steak easier to chew.
Uniform Slices: Ensure the slices are even so they cook at the same rate.

Make-Ahead Tips for Easy Prep

Fajitas are great for meal prepping, and with a few simple steps, you can make this dish even quicker on the day of cooking:

Marinate Early: Marinate the steak the night before for an easy, flavorful meal the next day.
Cut Veggies in Advance: Pre-chop your peppers and onions and store them in an airtight container in the fridge for up to 3 days.

Can Make Fajitas In The Oven?

To prepare your steak fajitas in the oven, start by preheating your oven to 400°F and lining a large baking sheet with parchment paper for easy cleanup. Arrange your sliced peppers and onions in a single layer on the sheet and bake them for 10 minutes. After that, give the veggies a stir and add your steak to the pan. Continue baking for another 5-10 minutes, depending on how well done you like your steak. For an extra bit of char and crispness, finish by broiling the steak and vegetables on high for 2-3 minutes

Storing and Reheating Leftovers

If you have any leftover steak fajitas (which might be unlikely!), store them in an airtight container in the refrigerator for up to 3-4 days. To reheat:

Microwave: Heat for 1-2 minutes until warmed through.
Skillet: Sauté in a hot skillet for a few minutes to re-crisp the edges of the steak.
Air Fryer: Pop them back in the air fryer at 350°F for a few minutes to warm and crisp.

Delicious Ways to Serve Steak Fajitas

While these steak fajitas are perfect wrapped in tortillas, there are several other ways to enjoy them:

Fajita Bowls: Serve over rice or quinoa and top with your favorite fajita toppings like guacamole, sour cream, and cilantro.
Fajita Salad: Make a fresh salad with steak and veggies, and drizzle with a lime vinaigrette.
Quesadillas or Nachos: Use leftover steak to create cheesy quesadillas or loaded nachos using homemade tortilla chips for a fun twist!
