Sliced flank or skirt steak with bell peppers and onions, seasoned with a bold fajita spice blend and cooked in the air fryer until slightly charred and juicy. Ready in about 12 minutes of cook time — weeknight-fast with restaurant-quality flavor.

Ingredients

Scale
  • 1.5 lbs flank steak or skirt steak, sliced into ½-inch strips against the grain
  • 3 bell peppers (red, yellow, green), sliced into strips
  • 1 large yellow onion, sliced into half-moons
  • 3 tablespoons olive oil
  • Juice of 1 lime
  • 3 cloves garlic, minced
  • Fajita Seasoning:
  • 2 teaspoons chili powder
  • 1 teaspoon cumin
  • 1 teaspoon smoked paprika
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • ¼ teaspoon cayenne (optional)
  • For Serving:
  • Flour tortillas, sour cream, guacamole, pico de gallo, shredded cheese, fresh cilantro, lime wedges

Instructions

  1. In a large bowl, combine the steak strips, sliced peppers, and onion. Add olive oil, lime juice, minced garlic, and the full seasoning blend. Toss to coat everything evenly.
  2. Marinate for at least 30 minutes at room temperature, or up to 4 hours in the refrigerator. Do not exceed 4–6 hours or the acid will affect the texture.
  3. Preheat the air fryer to 400°F for 3 minutes.
  4. Add the steak, peppers, and onions to the basket, spreading them into as close to a single layer as possible.
  5. Cook for 12 minutes, shaking or tossing with tongs at the halfway point. For medium-rare to medium, check at 10 minutes — steak should be browned outside and just slightly pink in the center. For well-done, continue to 14 minutes.
  6. Let the steak rest 3–4 minutes. Serve immediately in warm flour tortillas with your choice of toppings.

Notes

Always slice flank or skirt steak against the grain — this shortens the muscle fibers and is the single most important step for tender fajitas.

Do not overcook: medium or medium-rare keeps the steak juicy. Well-done strips go chewy quickly.

Avoid crowding the basket — if your air fryer is small, cook in two batches to prevent steaming and ensure caramelized edges.

Warm tortillas in the air fryer at 325°F for 45 seconds, or wrap in a damp paper towel and microwave for 20–30 seconds.

Cooked fajita filling reheats well in the air fryer at 375°F for 3–4 minutes.
