Ingredients

Protein and Vegetables

  • 1 pound sirloin steak or flank steak (sliced into ½ inch strips)
  • 1 large onion (thinly sliced)
  • 3 bell peppers (thinly sliced)

Seasoning and Finish

  • 2 tablespoons olive oil
  • 2 tablespoons taco seasoning
  • 1 lime (cut into wedges)

To Serve

  • Tortillas, warmed
  • Salsa
  • Cilantro leaves

Instructions

  1. Preheat oven: Preheat your oven to 400°F (204°C) and line a baking sheet with aluminum foil to make cleanup easier.
  2. Prepare the ingredients on the pan: Arrange the sliced steak in the center of the sheet pan, place the thinly sliced onions on one side, and the bell peppers on the other. Drizzle the olive oil evenly over the steak and vegetables, then sprinkle the taco seasoning on top. Use your hands to toss and coat the steak and vegetables evenly with the oil and seasoning. Place the lime wedges on the pan alongside.
  3. Cook the fajitas: Roast in the oven until the vegetables are tender and the steak is browned on the outside, about 10 to 12 minutes. Adjust cooking time to your preferred level of doneness.
  4. Add a citrus finish and serve: After cooking, squeeze the roasted lime wedges over the steak and vegetables for a bright, fresh flavor. Serve immediately with warmed tortillas, salsa, and fresh cilantro leaves as desired.

Notes

  • You can substitute sirloin steak with flank steak or skirt steak depending on availability and preference.
  • Taco seasoning can be store-bought or homemade for a fresh spice blend.
  • Adjust cooking time slightly if you prefer your steak rare or well done.
  • For a gluten-free meal, ensure the tortillas and taco seasoning are gluten-free.
  • Leftovers can be refrigerated up to 3 days and reheated in a skillet or oven for best texture.
