Ingredients

Scale
  • 1.5 lbs flank steak or skirt steak, sliced against the grain into 1/4-inch strips
  • 1/4 cup lime juice, fresh
  • 2 tablespoons olive oil, divided
  • 1 tablespoon chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 large yellow onion, sliced
  • 2 large bell peppers (any color), sliced
  • 8 small flour tortillas, warmed
  • Optional toppings: sour cream, salsa, guacamole, shredded cheese

Instructions

  1. In a bowl, combine the sliced steak with lime juice, 1 tablespoon of olive oil, chili powder, cumin, smoked paprika, oregano, salt, and pepper. Mix well to coat. Cover the bowl and marinate in the refrigerator for at least 30 minutes, or up to 4 hours for best flavor.
  2. Heat 1 teaspoon of olive oil in a large, heavy-bottomed skillet or cast-iron pan over medium-high heat until shimmering.
  3. Remove the steak from the marinade, letting excess drip off. Add half of the steak to the hot skillet in a single layer. Sear for 2-3 minutes per side until browned and cooked through. Remove the steak and set it aside on a plate. Repeat with the remaining steak, adding more oil if the pan is dry.
  4. Add the remaining 1 tablespoon of olive oil to the same skillet. Add the sliced onions and bell peppers. Cook, stirring occasionally, for 5 to 7 minutes until the vegetables are tender-crisp and slightly charred.
  5. Return all the cooked steak to the skillet with the vegetables. Toss everything together for 1 minute to reheat the meat and combine the flavors.
  6. Serve the sizzling steak fajitas immediately with warm tortillas and your choice of toppings.

Notes

  • For a sheet pan steak fajitas variation, toss the marinated steak and vegetables with 2 tablespoons of olive oil and spread them on a baking sheet. Bake at 400°F (200°C) for 15-20 minutes until the steak is cooked and vegetables are tender.
  • If you prefer a slow cooker steak fajitas method, combine the marinated steak, peppers, and onions in the slow cooker. Cook on low for 6-8 hours or high for 3-4 hours. Before serving, drain off excess liquid and shred or slice the beef.
  • To achieve the best sear and avoid steaming the meat, cook the steak in batches.
