Creating Sheet-Pan Steak Fajitas is straightforward when following the steps below:

1. Preheat the Oven: Set your oven to 400°F (200°C) to ensure it’s ready for roasting.
2. Marinate the Steak: In a large bowl, combine olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and black pepper. Add the sliced steak and toss until evenly coated. Let it marinate for at least 10 minutes.
3. Prepare the Vegetables: While the steak marinates, slice the bell peppers and onions. Add them to the bowl with the steak and toss to combine.
4. Spread on Sheet Pan: Transfer the steak and vegetable mixture to a parchment-lined sheet pan, ensuring even distribution for optimal roasting.
5. Roast in the Oven: Place the sheet pan in the preheated oven and roast for 20-25 minutes until the steak is cooked through and the vegetables are tender.
6. Add Lime Juice: Once cooked, remove the sheet pan from the oven and drizzle with fresh lime juice to enhance the flavor.
7. Garnish: Sprinkle chopped cilantro over the top for a fresh touch.
8. Serve: Enjoy the fajitas with warm tortillas for a true Tex-Mex experience.
