Leftover steak fajitas are a great way to use up extra meat you have on hand! Pan-seared peppers and onions get combined with juicy steak and a simple seasoning blend for a healthy, one pan wonder. Steak fajitas using leftover steak make the perfect easy weeknight dinner!
Mix all fajita seasoning ingredients together in a small bowl, set aside.
Warm tortillas over stovetop or in the microwave, keep warm in a tortilla warmer or foil. Prep all toppings so they're ready to serve immediately after steak is warmed.
Heat a large cast iron skillet over medium high heat, once heated add olive oil. Add onions and peppers to the pan and cook until peppers and onions are soft and beginning to blacken on the edges, stirring occasionally, about 4-6 minutes.
Reduce heat to medium and add the steak, fajita seasoning, beef broth and lime juice. Stir quickly and allow steak to warm through, taste and adjust seasoning. Do not overcook. Remove from heat and serve immediately.
Notes
Steak that was cooked to mid rare works best for this recipe as there's still some room to warm the meat along with the seasoning and veggies.
This fajita seasoning blend is very mild if you omit the cayenne pepper. Some chili powders can be spicy, so be sure to taste yours first.
Smoked chipotle powder can be substituted for the cayenne for an even more smoky heat.
If you don't have smoked paprika, substitute it for more chili powder, or regular paprika.
