In a small bowl, mix chili powder, smoked paprika, onion powder, brown sugar, ½ teaspoon kosher salt, garlic powder, cumin, and cayenne pepper.
1 teaspoon chili powder, ½ teaspoon smoked paprika, ½ teaspoon onion powder, ½ teaspoon brown sugar, ½ teaspoon + ¼ teaspoon kosher salt, ¼ teaspoon garlic powder, ¼ teaspoon ground cumin, ⅛ teaspoon cayenne pepper
Pat the steak dry and season it on all sides with the fajita seasoning mixture.
1 pound flank steak or boneless short ribs
Heat 2 tablespoons of olive oil in a large cast iron or stainless steel skillet over medium-high heat.
2 tablespoons + 1 tablespoon olive oil
Sear the steak for 3-6 minutes per side or until a meat thermometer inserted into the thickest part reads 135°F for medium rare. The cooking time depends on the cut and thickness of the steak. Transfer the steak to a plate, tent with foil, and let it rest for 10 minutes.
Add 1 tablespoon of olive oil to the skillet. Sauté the bell peppers and onion for 5-7 minutes until softened and starting to brown. They will pick up the seasoning leftover from the steak. Season the vegetables with an additional ¼ teaspoon of salt, if necessary. Remove the skillet from heat.
2 tablespoons + 1 tablespoon olive oil, 1 medium red bell pepper, 1 medium green bell pepper, 1 small yellow onion, ½ teaspoon + ¼ teaspoon kosher salt
Slice the rested steak across the grain into thin strips.
Serve the steak and sautéed vegetables on tortillas with your favorite toppings. Enjoy!
