Ingredients:

  • 1.5 lbs (680g) skirt steak, flank steak, or sirloin steak, trimmed and thinly sliced against the grain
  • 1/4 cup (60ml) lime juice, freshly squeezed
  • 1/4 cup (60ml) orange juice, freshly squeezed
  • 2 tablespoons (30ml) soy sauce
  • 2 tablespoons (30ml) olive oil
  • 1 tablespoon (15ml) Worcestershire sauce
  • 2 cloves garlic, minced
  • 1 tablespoon chili powder
  • 1 teaspoon cumin
  • 1/2 teaspoon smoked paprika
  • 1/4 teaspoon cayenne pepper (optional, for extra heat)
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon salt
  • 1 tablespoon olive oil
  • 1 large red bell pepper, sliced
  • 1 large green bell pepper, sliced
  • 1 large yellow onion, sliced
  • Salt and black pepper, to taste
  • 12-18 flour tortillas, warmed
  • Sour cream or Greek yogurt (optional)
  • Guacamole (optional)
  • Salsa (optional)
  • Shredded cheese (Cheddar, Monterey Jack) (optional)
  • Chopped cilantro (optional)
  • Lime wedges (optional)

Instructions:

  1. In a bowl or resealable bag, combine all marinade ingredients. Add the sliced beef, ensuring it's fully coated. Marinate in the refrigerator for at least 1 hour, or up to 2 hours for maximum flavor.
  2. While the beef is marinating, slice the bell peppers and onion.
  3. Heat olive oil in a large cast iron skillet over high heat until smoking hot. Add the marinated beef in a single layer (work in batches to avoid overcrowding the pan). Sear for 1-2 minutes per side, until nicely browned and cooked to your desired doneness. Remove beef from skillet and set aside.
  4. In the same skillet, add the sliced bell peppers and onions. Sauté until softened and slightly caramelized, about 5-7 minutes. Season with salt and pepper to taste.
  5. Slice the seared beef into thinner strips if desired. Add the beef back to the skillet with the vegetables. Toss to combine and heat through.
  6. Warm the tortillas according to package directions (microwave, dry skillet, or oven).
  7. Serve the sizzling beef and vegetable mixture with warmed tortillas and your favorite toppings. Let everyone assemble their own fajitas.
