Ingredients

Scale
  • 1.5 lbs flank steak or sirloin steak, thinly sliced
  • 2 tablespoons olive oil
  • 1 large onion, sliced
  • 2 bell peppers (any color), sliced
  • 1 teaspoon chili powder
  • 1 teaspoon ground cumin
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon dried oregano
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper
  • 2 tablespoons lime juice (freshly squeezed is best)
  • 1 tablespoon Worcestershire sauce
  • For Serving: Warm tortillas, salsa, sour cream, avocado slices

Instructions

  1. In a medium bowl, combine the sliced steak with lime juice, Worcestershire sauce, chili powder, cumin, smoked paprika, garlic powder, oregano, salt, and pepper. Toss to coat the steak completely. Let the steak marinate for at least 15 minutes while you prepare the vegetables.
  2. Heat 1 tablespoon of olive oil in a large skillet or cast-iron pan over medium-high heat. Add the sliced onions and bell peppers. Cook, stirring occasionally, for 5 to 7 minutes until the vegetables are tender-crisp. Remove the vegetables from the skillet and set them aside on a plate.
  3. Add the remaining 1 tablespoon of olive oil to the same hot skillet. Add the marinated steak strips in a single layer, working in batches if necessary to avoid overcrowding the pan. Sear the steak for 2 to 3 minutes per side until browned and cooked to your preferred doneness.
  4. Return the cooked vegetables to the skillet with the steak. Toss everything together for 1 minute to reheat the vegetables and combine the flavors.
  5. Serve the steak fajitas immediately with warm tortillas and your choice of toppings like salsa, sour cream, or avocado slices.

Notes

  • For the juiciest steak, slice the meat against the grain before marinating.
  • If you prefer a slow cooker steak fajitas option, you can combine the marinated steak and vegetables and cook on low for 4-6 hours.
  • This recipe works well for healthy steak fajitas bowls when served over rice or quinoa instead of tortillas.
