Fajita Seasoning

For this recipe, you can either use store bought fajita seasoning, or two table spoons (about a packet’s worth of store bought seasoning) from our easy Fajita Seasoning recipe below:

  • 2 teaspoons chili powder
  • 1 teaspoon salt
  • 1 teaspoon paprika
  • ½ teaspoon onion powder
  • ½ teaspoon garlic powder
  • ¼ teaspoon cayenne pepper
  • ½ teaspoon ground cumin

Beef Fajita Marinade

To make our beef as flavorful as possible – and extra tender and juicy – we recommend marinating with oil, fajita spices, and lime juice for at least 30 minutes to overnight before cooking.

Combine oil and spices and pour over steak, letting it tenderize and soak up all that flavor!

How To Make Fajitas

For the best flavor, we recommend first cooking the bell peppers – let them brown to get the best smoky, caramelized flavor – before cooking the steak in the pan.

You can use the same pan, and don’t need to clean it out after cooking the bell peppers in it (the flavor will give a bit of extra yum to the steak), so it works as a one-pot dinner!

When are Beef Fajitas Cooked

We recommend using a digital thermometer to gauge your flak or skirt steaks doneness for fajitas, using the handy steak temperature guide below.

Cook your steak to your preferred doneness – whether you like red, pink, or well done!

  • 125 degrees Fahrenheit – Rare
  • 135 degrees Fahrenheit – Medium Rare
  • 145 degrees Fahrenheit – Medium
  • 150 degrees Fahrenheit – Medium Well
  • 160 degrees Fahrenheit – Well Done

How To Make Fajita Salad

Make and mix your salad before adding steak to the top for a pretty, easy to eat salad.

We recommend mixing and dressing only as much lettuce as you will realistically eat. While the steak can be stored for up to four days in the refrigerator, dressed salad starts to wilt incredibly quickly and should not be kept after your meal.
