Frequently Asked Questions
Can I cook the fajitas in the oven instead of an air fryer? Yes, you can bake the fajitas in a preheated oven at 400°F (200°C). Place the marinated steak and vegetables on a baking sheet and roast for 15-20 minutes, or until the steak is cooked to your liking and the vegetables are tender.
What kind of peppers work best for fajitas? A mix of red, green, and yellow bell peppers is classic for fajitas, offering a balance of sweetness and slight bitterness. If you prefer spicier flavors, incorporate poblano or jalapeño peppers into the mix.
How do I prevent the steak from overcooking in the air fryer? Monitoring the air frying time is crucial. Since air fryers vary, check the steak a minute or two before the recommended time. Looking for a slight browning is your cue. Additionally, allow the steak to rest for a few minutes before slicing, keeping it juicy.
