How to Make Air Fryer Beef Fajitas

1. Start by slicing the beef tenderloin into thin, fajita-style strips. Try to keep them uniform so they cook evenly.
2. Slice the bell peppers and onion into similar-sized strips so everything finishes at the same time.
3. Place the peppers and onions into a mixing bowl. Drizzle lightly with oil and sprinkle with 1–2 tablespoons of fajita seasoning. Toss until evenly coated.
4. Transfer the seasoned vegetables to the air fryer basket, spreading them out into an even layer.
5. In the same bowl, add the sliced beef. Drizzle with a little oil and season with the remaining fajita seasoning. Toss until well coated.
6. Layer the beef directly on top of the vegetables in the air fryer basket.
7. Cook at 380°F for 10 minutes, shaking or tossing halfway through so everything cooks evenly and gets nicely browned.
8. Remove from the air fryer and let the fajita mixture rest for a minute so the juices settle.
9. Warm your tortillas and load them up with the beef and veggies. Add your favorite toppings like sour cream, cilantro, salsa, queso fresco, and a squeeze of lime.

The first time I made these, my family heard the air fryer humming and the noses started sniffing around.

By the time I brought the tortillas out, it turned into a full fajita-building station with opinions on toppings and who grabbed the last tortilla. Now fajita night is one of those dinners where nobody complains—and that’s a major win in my house.
