Ingredients

Scale
  • 1.5 lbs skirt steak or flank steak, sliced against the grain into thin strips
  • 2 large bell peppers (any color), sliced
  • 1 large yellow onion, sliced
  • 2 tablespoons olive oil
  • 1 tablespoon chili powder
  • 1 teaspoon cumin
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon cayenne pepper (optional)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • Juice of 1 lime
  • Warm flour or corn tortillas for serving
  • Optional toppings: salsa, sour cream, avocado, cilantro

Instructions

  1. Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easier cleanup.
  2. In a large bowl, combine the sliced steak, bell peppers, and onion.
  3. In a small bowl, whisk together the olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, cayenne pepper (if using), salt, and black pepper to create the seasoning mix.
  4. Pour the seasoning mix over the steak and vegetables. Toss everything together until the steak and vegetables are evenly coated.
  5. Spread the steak and vegetable mixture in a single layer on the prepared baking sheet. Do not overcrowd the pan; use two sheets if necessary to ensure everything roasts instead of steams.
  6. Bake for 12 to 15 minutes, or until the steak is cooked through and the vegetables are tender-crisp. For a slight char, you can switch the oven to broil for the last 1-2 minutes, watching carefully to prevent burning.
  7. Remove the pan from the oven. Squeeze the fresh lime juice over the hot steak and vegetables. Toss gently.
  8. Serve immediately with warm tortillas and your favorite toppings for a sizzling fajita experience.

Notes

  • For the juiciest steak, use skirt steak and slice it thinly against the grain.
  • If you prefer a deeper flavor, marinate the seasoned steak and vegetables for 30 minutes before baking.
  • This sheet pan steak fajitas recipe works well for meal prep; store components separately and reheat just before serving.
