Ingredients
For the Fajitas
- 1½ pounds sirloin steak, thinly sliced against the grain
- 2 bell peppers (red, green, or yellow), sliced
- 1 large onion, sliced
- 1 tablespoon olive oil
- 2 tablespoons fajita seasoning
- ½ teaspoon garlic powder
- ½ teaspoon smoked paprika (optional)
- Salt and black pepper, to taste
- Juice of ½ lime
- Fresh chopped cilantro (optional)
For Serving
- Warm flour or corn tortillas
- Sour cream
- Guacamole
- Salsa or pico de gallo
- Shredded cheddar or Mexican cheese blend
- Lime wedges
Step-by-Step Method
Step 1: Prepare the Ingredients
Slice the sirloin steak into thin strips against the grain. Slice the bell peppers and onion into similar-sized strips.
Step 2: Season Everything
In a large bowl, combine the steak, peppers, and onions. Add the olive oil, fajita seasoning, garlic powder, smoked paprika, salt, and pepper. Toss everything together until evenly coated.
Step 3: Cook
Heat a large skillet, cast-iron pan, or air fryer (depending on your preferred method).
Cook at 400°F (200°C) for about 12–15 minutes, tossing the mixture halfway through and once more near the end of cooking. The steak should be browned, and the vegetables should remain slightly crisp.
Step 4: Finish
Squeeze fresh lime juice over the fajitas and sprinkle with chopped cilantro before serving.
