Step-by-Step Instructions
- Slice the beef correctly.
This matters. Slice the steak thin and against the grain. This keeps it tender instead of chewy. If the steak fights you, pop it in the freezer for 10 minutes first—game changer. - Season everything.
In a large bowl, toss steak, peppers, and onions with olive oil. Add chili powder, cumin, paprika, garlic powder, onion powder, salt, and pepper. Toss until everything looks evenly coated and confident. - Preheat the air fryer.
Set it to 390°F (200°C) and preheat for 3–5 minutes. Preheating helps the beef sear instead of steam. - Air fry the fajitas.
Add the beef and veggies to the air fryer basket in a loose, even layer. Cook for 10–12 minutes, shaking or tossing halfway through. You want the beef cooked and the veggies tender with a little char. - Check for doneness early.
Thin beef cooks fast. Start checking at 9 minutes to avoid overcooking. The steak should be juicy and just cooked through. - Rest briefly.
Let everything sit for 2 minutes before serving. This keeps the beef juicy. - Serve hot.
Pile into warm tortillas or serve fajita-style bowls. Add lime juice and cilantro if you’re feeling fancy.
Common Mistakes to Avoid
- Slicing with the grain. That’s how tough fajitas happen.
- Overcrowding the basket. Cook in batches if needed—air needs space.
- Skipping preheat. You’ll miss that seared, fajita-style flavor.
- Overcooking the steak. Thin slices go from perfect to dry fast.
- Under-seasoning. Fajitas should be bold, not shy.
Thinking “just one more minute” is risky business here.
Alternatives & Substitutions
- Different cuts: Sirloin works great; ribeye is extra juicy (and indulgent).
- Chicken swap: Use chicken breast or thighs with the same seasoning.
- Veggie-only: Double the peppers and onions; add mushrooms or zucchini.
- Low-carb: Skip tortillas and serve over cauliflower rice or salad.
- Spicy: Add cayenne, chili flakes, or sliced jalapeños.
- Store-bought seasoning: Totally fine—use about 2 tablespoons.
IMO, homemade seasoning tastes better, but convenience wins on busy nights.
What to Serve With Beef Fajitas
- Warm flour or corn tortillas
- Mexican-style rice or cilantro-lime rice
- Black beans or refried beans
- Guacamole, salsa, sour cream
- Simple side salad
Grandmom rule: if it’s fajitas, there should be options on the table.
Tips for Extra Juicy Air Fryer Fajitas
- Use a little oil. Fat = flavor and moisture.
- Don’t marinate too long. Thin beef doesn’t need it.
- Shake halfway. Ensures even cooking and light charring.
- Finish with lime. Acid wakes everything up instantly.
- Warm tortillas properly. Cold tortillas ruin the vibe.
Bold tip: A squeeze of lime right before serving makes everything taste brighter.
FAQ (Frequently Asked Questions)

You can, but thawed beef cooks more evenly and stays juicier.
Why are my fajitas watery?
Too many veggies or overcrowding the basket. Cook in batches if needed.
Do I need to marinate the steak?
Not necessary. Thin slicing and proper seasoning do the job.
Is this kid-friendly?
Yes! Just go light on chili powder if needed.
Can I double the recipe?
Absolutely—just cook in batches so everything browns properly.
How do I reheat leftovers?
Air fry at 350°F for 3–4 minutes until warm. Still juicy.
