  • Total Time: 30 minutes
  • Yield: 4 servings

Ingredients

Meat and Seasonings

  • 2 tbsp olive oil, divided
  • 1.25 pound sirloin steak (or skirt steak or flank steak)
  • 1 tsp cumin
  • 1/2 tsp chili powder
  • 1/2 tsp paprika
  • 1/4 tsp cayenne pepper
  • Salt and pepper, to taste

Vegetables

  • 1 large sweet onion, sliced
  • 3 garlic cloves, minced
  • 1 red bell pepper, sliced
  • 1 green bell pepper, sliced

Instructions

  1. Heat the skillet: Heat a large cast iron skillet over high heat and add 1 tablespoon of olive oil to coat the surface evenly.
  2. Season the steak: In a small bowl, combine cumin, chili powder, paprika, and cayenne pepper. Sprinkle this seasoning mix evenly on both sides of the sirloin steak, adding salt and pepper to taste.
  3. Sear the steak: Place the seasoned steak in the hot skillet. Sear each side for 3-5 minutes until browned and cooked to your preferred doneness (about 3 minutes per side for medium rare). Remove the steak from skillet and set aside to rest on a plate.
  4. Sauté onions and garlic: Lower the heat to medium and add the remaining 1 tablespoon of olive oil to the skillet. Add the sliced onions and minced garlic, sautéing for 1-2 minutes until onions start to soften and the garlic releases its aroma.
  5. Cook bell peppers: Add the sliced red and green bell peppers to the skillet and continue sautéing for 2-3 minutes until the peppers reach your desired tenderness. Remove the skillet from heat.
  6. Slice and combine: Once the steak has rested, slice it thinly or chop into bite-sized pieces. Toss the steak strips together with the sautéed onions and bell peppers to combine flavors before serving.

Notes

  • For best flavor and tenderness, let the steak rest after searing to retain juices.
  • You can substitute sirloin with skirt or flank steak for variations.
  • Serve with warm tortillas, guacamole, salsa, and sour cream for a full fajita experience.
  • Adjust cayenne pepper according to your preferred spice level.
  • Use a cast iron skillet or a heavy-bottomed pan for best searing results.
