Grilled Steak Fajitas

Grilled steak fajitas are more flavorful than anything you have been served in your favorite Tex-Mex restaurant as the beef, peppers, and onions soak up the intoxicating flavor of the smoke and flames.

  • 1 pound Skirt Steak
  • 1/2 packet Fajita Seasoning (Full packets are typically around 1.25 oz)
  • 2 tablespoons Olive Oil
  • 1 tablespoon Low Sodium Soy Sauce
  • 1 Limes (juiced)
  • 2 Bell Peppers (sliced)
  • 1 Red Onion (Sliced)

Toppings as Desired

  • Sour Cream
  • Guacamole
  • Flour Fajita Tortillas


  • Add skirt steak to a gallon plastic bag and sprinkle with fajita seasoning, then add olive oil, soy sauce, and lime juice. Turn bag to evenly coat all of the meat.
  • Optional, but recommended: Let marinate for 1 hour.
  • Place peppers and onions in a vegetable grill basket (see note) and set over hot grill until peppers and onions are heated through and charring, but not excessively tender. Remove from grill and set aside.
  • Place skirt steak over the hottest part of the grill and cook until the exterior browns and the interior reaches your desired temperature. (135 for medium rare).
  • Remove skirt steak from the grill and let rest for 5 minutes. While skirt steak is resting lightly toast each fajita tortilla.
  • After resting, thinly slice skirt steak against the grain.


  • Serve fajitas by placing steak, peppers, and onions on tortillas with desired toppings.


If you do not have a vegetable grill basket, you can use aluminum foil instead with reasonable success.
