How to Grill Steak Fajitas

Now that you have everything you’ll need to make this tasty dinner, let’s dive into the recipe. Here’s how to grill steak fajitas.

  1. Preheat. Fire up the grill and preheat to High heat (450 degrees F). While the grill preheats, place a grill basket on the grill to preheat as well.
  2. Season. Coat the onions and peppers in avocado oil and then season with 1 Tablespoon of Fiesta Rub. Next, season the steak with the remaining Fiesta Rub.
  3. Grill. Place the onions and peppers into the preheated grill basket. Lay the seasoned steak directly on the grill grates. Leave the lid open on the grill and cook until the steak reaches your preferred doneness (125 degrees F for Rare, 135 degrees F for Medium Rare, or 145 degrees for Medium). Remove the peppers and onions when they are slightly charred and softened. Allow the steak to rest for 5 minutes.
  4. Grill the tortillas. Place a 12-inch cast iron skillet on the grill. Place a tortilla in the skillet and cook until just warmed through. Repeat until you have heated all the tortillas. Wrap the tortillas in foil to keep them warm.
  5. Serve. Slice the steak very thinly. Place the steak and vegetables in the skillet and serve with your favorite toppings.

Tips for Grilling Steak Fajitas

Here are some tips for making grilling steak fajitas. These guys are fairly easy to make, but I’m throwing in some BBQ knowledge to help you get the best results.

  • Grab the right cut of steak. The best cuts for fajitas are thin, well-marbled, quick-cooking steaks with lots of surface area to pick up that signature fajita char. Flap steak, skirt steak, or flank steak are my top choices. They are naturally tougher cuts, but sliced thin against the grain, they will melt in your mouth!
  • Get sweeter bell peppers. Most restaurants use green bell peppers (they are the cheapest), but I prefer the sweeter red, orange, and yellow peppers. They caramelize so beautifully when cooked over high heat.
  • Have the right tools. A good metal grill basket makes grilling the vegetables super easy and adds all of that tasty charred flavor from the high heat.
  • Heat up a skillet! While your grill is already hot and your meat is resting, throw a seasoned cast iron skillet on your grill. Right before serving, add your vegetables and sliced steak to the hot skillet. You’ll have a restaurant-style presentation right at home!
