Ingredients Equipment Method

Ingredients
  

  • 1 lb flat iron steak cut into thin strips
  • 2 bell peppers preferably different colors, sliced
  • 1 onion sliced thin
  • 2 tablespoons olive oil
  • 1 clove garlic minced
  • 1 teaspoon cumin ground
  • 1 teaspoon chili powder
  • Salt to taste
  • Freshly ground black pepper to taste

Equipment

  • Cast iron skillet
  • Sharp knife

Method
 

  1. Trim the steak and slice it into thin strips against the grain. Set aside.
  2. Heat the cast-iron skillet over high heat until very hot. Add a tablespoon of olive oil, swirling to coat the surface.
  3. Add the steak strips to the skillet in a single layer, searing for about 2-3 minutes without moving them, until they develop a deep brown crust.
  4. Flip the steak and cook for another 1-2 minutes, until just cooked through but still juicy. Remove the steak from the skillet and set aside.
  5. Add another tablespoon of olive oil to the skillet, then toss in the sliced peppers and onions. Sauté them over medium-high heat for about 5-6 minutes, stirring occasionally, until they soften and start to caramelize around the edges.
  6. Add minced garlic, cumin, and chili powder to the vegetables. Stir well and cook for another minute until fragrant.
  7. Return the cooked steak to the skillet, tossing everything together. Cook for another 1-2 minutes until everything is heated through and well combined. Season with salt and pepper to taste.
  8. Remove from heat and serve immediately with warm tortillas, garnishes, or your favorite sides. Enjoy the vibrant, tender, and juicy fajitas!
