Ingredients
  

  • 2 pounds skirt or flank steak cut into 1-inch cubes
  • 1 large red bell pepper thinly sliced (1/4 inch thick)
  • 1 small yellow onion peeled and thinly sliced (1/4 inch thick)
  • 4.5 teaspoons chili powder
  • 1.5 teaspoons ground cumin
  • 1.5 teaspoons smoked paprika
  • 1 teaspoon dried oregano
  • 0.75 teaspoon garlic powder
  • 0.5 teaspoon onion powder
  • 0.25 teaspoon cayenne pepper
  • 1 tablespoon kosher salt
  • 2 tablespoons extra virgin olive oil
  • 2 tablespoons fresh lime juice
  • 3 tablespoons green onions finely chopped
  • flour or corn tortillas for serving

Equipment

  • Large sheet pan
  • Large mixing bowl
  • Small mixing bowl
  • meat thermometer

Method
 

  1. Preheat your oven to 375°F.
  2. In a large bowl, combine cubed steak, bell pepper, and onion, mixing well for even cooking.
  3. In a separate small bowl, whisk together all spices and salt to create a well-blended fajita spice mix.
  4. Pour olive oil over steak and vegetables, add 4 tablespoons of spice mixture, and toss thoroughly to coat each piece.
  5. Let the mixture sit at room temperature for at least 20 minutes to absorb flavors.
  6. Line sheet pan with parchment paper and spread mixture in a single layer.
  7. Bake for 10-12 minutes until steak is browned, stirring halfway through for even cooking.
  8. Check internal temperature with meat thermometer: 130-135°F for medium-rare or 145°F for medium.
  9. Remove from oven and toss with fresh lime juice and chopped green onions before serving.
  10. Serve in warmed tortillas with desired toppings like sour cream, guacamole, and salsa.

Notes

Skirt steak is traditional but flank steak works as substitute. Slice against grain for tender meat. Let steak sit at room temperature 30 minutes before cooking for best results.
