Marinate the Beef & Veggies
In a large mixing bowl, combine the beef strips with olive oil, cumin, paprika, garlic powder, salt, and pepper.

Add the sliced onions and bell peppers. Mix thoroughly to coat everything evenly.

Let the mixture marinate for 15–20 minutes. This allows the spices to penetrate the beef and vegetables.

💡 Tip: You can prep this the night before and refrigerate for a stronger flavor infusion.

Preheat the Air Fryer
Preheat your air fryer to 200°C (400°F) for 5 minutes.

Air Fry the Fajita Mix
Place the marinated beef, peppers, and onions into the air fryer basket.

Spread them out for even airflow.

Cook at 200°C (400°F) for 10–12 minutes, shaking the basket or stirring halfway through to ensure everything cooks evenly.

🔥 The beef should be browned and the vegetables slightly charred around the edges.

Serve the Fajitas
Warm up your tortillas in a pan, microwave, or directly over a flame for that charred flavor.

Spoon the beef and veggie mix onto the tortillas.

Finish with a squeeze of fresh lime juice and a sprinkle of chopped cilantro.

🌮 Serving Suggestions

Classic Style: Serve with sour cream, guacamole, shredded cheese, or salsa.

Meal Prep: Store leftovers in the fridge for up to 3 days and reheat in the air fryer.
