Ingredients

For the Steak and Veggies:

  • 1 lb flank steak (or skirt steak), thinly sliced against the grain

  • 1 red bell pepper (sliced)

  • 1 yellow bell pepper (sliced)

  • 1 onion (sliced)

  • 2 tablespoons olive oil

  • 1 tablespoon lime juice

For the Fajita Seasoning:

  • 1 tablespoon chili powder

  • 1 teaspoon cumin

  • 1 teaspoon smoked paprika

  • 1/2 teaspoon garlic powder

  • 1/2 teaspoon onion powder

  • 1/2 teaspoon dried oregano

  • 1/4 teaspoon salt

  • 1/4 teaspoon black pepper

For Serving:

  • Flour or corn tortillas

  • Fresh cilantro (chopped, for garnish)

  • Lime wedges (for serving)

  • Sour cream or guacamole (optional, for serving)

Instructions

  • Preheat the Oven: Preheat your oven to 425°F (220°C) and line a large sheet pan with parchment paper or aluminum foil for easy cleanup.

  • Prepare the Fajita Seasoning: In a small bowl, combine chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, and black pepper. Stir until the spices are well mixed.

  • Season the Steak and Vegetables: In a large bowl, toss the thinly sliced steak, bell peppers, and onion with olive oil, lime juice, and the fajita seasoning. Make sure everything is evenly coated.

  • Arrange on the Sheet Pan: Spread the seasoned steak and vegetables evenly on the prepared sheet pan in a single layer.

  • Bake: Bake in the preheated oven for 18-20 minutes, or until the steak is cooked to your desired level of doneness and the vegetables are tender. Stir halfway through the cooking time for even cooking.

  • Serve: Once cooked, remove the sheet pan from the oven. Serve the steak and veggies on warm tortillas and garnish with fresh cilantro, a squeeze of lime, and your favorite toppings like sour cream or guacamole.


Notes

Vegetarian Version: Replace the steak with marinated tofu or portobello mushrooms for a plant-based version.Spicy Kick: Add sliced jalapeños or a sprinkle of red pepper flakes to the veggies for extra heat.Add More Veggies: Feel free to add more vegetables like zucchini, corn, or cherry tomatoes for added flavor and color.
