Prepare the Steak: Slice the steak into thin strips against the grain. This helps to ensure the beef is tender and cooks evenly in the air fryer. In a bowl, toss the steak strips with 1 tablespoon of olive oil, soy sauce, garlic powder, paprika, black pepper, and salt. Allow it to marinate for 5-10 minutes.
Preheat the Air Fryer: Preheat your air fryer to 400°F (200°C). This ensures that the steak cooks evenly and gets a nice, crispy texture.
Air Fry the Steak: Arrange the marinated steak strips in a single layer in the air fryer basket. Cook for 10-12 minutes, flipping halfway through, until the steak is golden brown and cooked to your desired level of doneness.
Prepare the Vegetables: While the steak is cooking, slice the bell pepper and onion into thin strips. Set them aside to be cooked with the steak in the next step.
Cook the Vegetables: After the steak is done, remove it from the air fryer and set it aside. In the same air fryer basket, add the bell peppers and onions. Lightly drizzle them with a little olive oil and cook for 4-5 minutes, until tender and slightly charred.
Combine and Serve: Once the vegetables are cooked, return the steak to the air fryer basket with the peppers and onions. Stir everything together, making sure the steak is well-coated in the pepper sauce. Serve immediately over a bed of rice or alongside a fresh salad.
