This Steak Fajita Recipe is one that I developed several months ago. With a few tweaks, I got it perfect . . . but then the holidays came and I needed to give you the best green bean casserole for Thanksgiving. And then I needed to give you the perfect Holiday Sangria before Christmas.

In the mean time, I have made it regularly for my family. It has become a staple in our house. It is Quinn’s favorite dinner and the last time we had it . . . you guys, she ate SEVEN fajitas.

I think we can agree these are amazing.

HOW TO MAKE STEAK FAJITAS

The key to this recipe is marinating flank steak (or skirt steak) in a nice fajita marinade. This recipe is really similar to my Steak Fajita Kabobs, but we are making it indoors.

Marinate your steak with your vegetables for at least 20 minutes, but no longer than 24 hours. When meat is marinated too long, it starts to break down the fibers in the meat and you end up with mushy meat.

When ready to eat, cook the steak in a preheated cast iron skillet. Then let it rest, tented with foil, and cook the vegetables in the same skillet. Slice your meat really thin, and serve it all in tortilla shells.

WHAT CUT OF MEAT FOR STEAK FAJITAS

You can get either flank steak or skirt steak to make this recipe. Both are great cuts of meat for marinating and grilling.

Worth noting, flank steak and skirt steak are not the same thing. They both come from a similar area of the cow, but they are different cuts. Either, however, can be used in this recipe.

STEAK FAJITA MARINADE

These steak fajitas are so amazing because of the marinade. It is made from:

  • olive oil
  • lime juice
  • chili powder
  • salt
  • paprika
  • oregano
  • garlic powder
  • onion powder

Given how much my family loves this recipe as is, I’m really reluctant to tell you the following.

In a pinch you can substitute the seasoning in this with a store bought fajita package.

That said, I would stick to this recipe whenever possible. It’s just the perfect balance of flavors.

As mentioned above, we marinate the steak with the vegetables for between 20 minutes and 24 hours.

Marinating the meat between 20 minutes and 2 hours will add flavor. Marinating for between 6 hours and 24 hours will add flavor and tenderize the meat.

This is a great recipe to make the night before and throw in the skillet when you get home from work.

COOKING THE STEAK AND THE VEGETABLES AT THE SAME TIME

The recipe is written assuming that you have one skillet to work with.

I am lucky enough to have an indoor cast iron stove top grill. Though I have made it every way under the sun, my preference is to grill my steak on that while cooking my vegetables in the cast iron skillet.

DOUBLE THE MEAT

If you are eating with meat lovers like me, you may want to double the meat in this recipe.

If you do that, also double the marinade. You can still marinate it all together in one giant zip lock bag. I usually keep the amount of vegetables the same when I double the meat. Again, I live with a family of t-rex’s.

SERVING

We love eating this family style.

We bring the vegetables over to the table in the hot cast iron skillet. We slice the meat on a big cutting board right on the table, and then every makes their fajitas at the table.

My kids like their fajitas with a little cheese on top. My husband prefers his with some sour cream. I like mine with a little fresh cilantro.

    Thought for sure I had lime juice, but do not and do not wait to make a run to the store for just that. Will lemon juice work as well?

    • Lisa Longley says

      Amanda, I can’t tell you how badly I want to say yes to this. But I’m afraid that it would affect the taste in a not great way. Sorry!
