Instructions
- Preheat and Prepare: Preheat your oven to 400°F (204°C) and line a baking sheet with foil for easy cleanup. Slice the flank steak into ½ inch strips to ensure even cooking.
- Make the Marinade: In a small bowl, whisk together 2 tablespoons of olive oil, 1 ½ tablespoons fajita seasoning, and 1 tablespoon lime juice to create the marinade that will infuse the steak with flavor.
- Marinate the Steak: Place the sliced steak in a resealable bag, pour the marinade over it, seal, and let it rest while you prepare the vegetables. This allows the flavors to penetrate the meat.
- Prepare the Vegetables: Slice the yellow onion and bell peppers into ½ inch strips. Toss them in a bowl with the remaining 2 tablespoons olive oil, 1 ½ tablespoons fajita seasoning, and salt and pepper to taste, ensuring the veggies are well coated.
- Arrange on Sheet Pan: Spread the seasoned vegetables evenly on the foil-lined baking sheet, leaving space for the steak strips next to them. This arrangement ensures even cooking and flavor mingling.
- Bake: Place the sheet pan in the oven and bake for 12-15 minutes, tossing and turning the steak and vegetables halfway through to promote even cooking and caramelization.
- Prepare Tortillas and Garnishes: While the fajita mix bakes, lightly toast your small flour or corn tortillas. Slice the limes and chop cilantro to prepare fresh accompaniments.
- Serve: Once the steak is cooked to your liking and vegetables are tender, remove from the oven. Let the mixture cool slightly for a few minutes, then serve with the toasted tortillas, lime wedges, cilantro, and optional avocado for a complete meal.
Notes
- Use flank steak for best results, but skirt steak can be substituted.
- Adjust fajita seasoning to your taste or use a homemade blend.
- To keep tortillas warm, wrap them in foil after toasting.
- Optional avocado adds creaminess and balances the spices.
- Use corn tortillas for gluten-free option.
- For extra char, broil for 1-2 minutes after baking if desired.
