How to Make Air Fryer Steak Fajitas Recipe
Step 1: Marinate the Steak
Start by slicing your flank steak against the grain into thin strips to ensure maximum tenderness. In a bowl, combine the soy sauce, taco seasoning, garlic paste, olive oil, and lime juice. Toss the steak strips in this marinade and let them soak up the flavors for at least 15 minutes. This simple marinade not only enhances the beef’s taste but also helps in tenderizing the meat for that perfect bite.
Step 2: Prepare the Vegetables
While your steak is marinating, slice the red onion and bell peppers into thin strips. Toss them in olive oil and the remaining tablespoon of taco seasoning. This ensures the vegetables carry their own punch of flavor and crisp up delightfully when air fried. The mix of colors from the bell peppers will make your fajitas visually stunning and add a fresh crunch.
Step 3: Air Fry the Steak and Vegetables
Preheat your air fryer to 400°F (200°C). Lay the marinated steak strips in the air fryer basket in a single layer (you may need to cook in batches). Cook for about 7-8 minutes, shaking the basket halfway through for even cooking. Once done, remove the steak and add the seasoned vegetables to the basket. Air fry the veggies for 6-7 minutes until they soften slightly but still retain some crunch and char.
Step 4: Combine and Serve
Return the steak strips to the basket with the cooked vegetables and give everything a gentle toss to mix the flavors before serving. This method ensures that the steak remains juicy, and the veggies perfectly tender-crisp.
How to Serve Air Fryer Steak Fajitas Recipe

Garnishes
To truly make this Air Fryer Steak Fajitas Recipe shine, don’t skip the garnishes. Fresh cilantro, a dollop of creamy sour cream, slices of ripe avocado, and a sprinkle of shredded cheese bring vibrant layers of taste and texture. A wedge of lime on the side is perfect for that extra zing of freshness right before you dive in.
Side Dishes
Serve your fajitas with warm tortillas — flour or corn, the choice is yours! For a heartier meal, Mexican rice or cilantro-lime quinoa pairs beautifully, soaking up all the juices and flavors. A simple side of black beans or a crisp green salad with a tangy dressing also complements the dish perfectly without overwhelming it.
Creative Ways to Present
Want to impress your guests? Serve these steak fajitas as a colorful platter where everyone can build their own wraps. Lay out bowls of fajita mix, toppings, and salsas. Alternatively, try stuffing them into warm pita pockets or layering them with rice and beans for a vibrant fajita bowl experience. The possibilities to customize are endless, making this recipe a crowd-pleaser every time.
Make Ahead and Storage
Storing Leftovers
Any leftovers from this Air Fryer Steak Fajitas Recipe keep really well in an airtight container in the fridge for up to 3 days. Make sure to separate the steak and vegetables for the best texture upon reheating.
Freezing
If you want to save fajitas for longer, you can freeze the cooked steak and veggies separately in freezer-safe bags or containers for up to 2 months. Make sure to cool everything completely before freezing to maintain freshness.
Reheating
To reheat, gently warm the steak and vegetables in a skillet over medium heat or toss them back into the air fryer for a few minutes to restore that signature crispness. Avoid microwaving if possible, as it can leave the meat rubbery and the veggies soggy.
FAQs
Can I use other cuts of steak for this Air Fryer Steak Fajitas Recipe?
Absolutely! While flank steak is ideal for its tenderness and flavor, skirt steak, sirloin, or even ribeye strips can work beautifully. Just ensure they’re sliced thinly against the grain for the best texture.
Do I need to marinate the steak overnight?
Not necessary! While marinating overnight intensifies flavors, even 15-30 minutes of marination will give your steak a lovely depth without taking up extra prep time.
Can I add other vegetables?
Definitely! Mushrooms, zucchini, or even cherry tomatoes can be fantastic additions. Just adjust the cooking times slightly to make sure everything cooks evenly without becoming mushy.
Is the Air Fryer better than cooking on the stove?
The air fryer is a fantastic shortcut that delivers those crispy edges and juicy centers with less oil and fuss. It also keeps the cooking process contained and quick, perfect for busy days when you still want fresh, vibrant fajitas.
What toppings do you recommend for steak fajitas?
Classic toppings such as guacamole, sour cream, pico de gallo, fresh cilantro, and lime wedges are always winners. You can also experiment with pickled jalapeños or a sprinkle of cotija cheese for extra zing and texture.
