Quick and easy dinner, in less than 30 minutes cook time, can be yours! These sheet pan steak fajitas are a great way to feed a crowd easily!

Taco night happens at least once a week in our home. Well, twice a week, usually, but who’s counting? 

Changing tacos with ground beef up for fajitas is a tasty way to keep our taco nights from getting boring. I love how quickly these sheet pan fajitas come together. They are better if you can prepare them the day before, and allow them to marinade overnight. However, a couple hour marinade is good as well.

What kind of steak can I use for these steak fajitas?

They are commonly made with skirt steak. It’s a tougher cut, but perfect for super thin slicing, flavorful marinades, and rapid cooking. However, you can also use thin cut sirloin, strip, or even ribeye if you want. Flank steak is usually cheaper in our area, so that’s more often my choice. 

What’s the difference between flank and skirt steak?

Chances are, if you’ve eaten fajitas in a restaurant, you have eaten skirt steak. Skirt steak can have a more rich flavor than flank steak and should only be cooked to a medium rare temperature for best flavor and texture. It’s the classic steak for fajitas. 

However, flank steak can also lend itself to this recipe, as it’s great for high heat and quick searing.  Both cuts are lean, and have a lot of tough fibers, and can be used interchangeably for most recipes.

How do you make the flank or skirt steak in steak fajitas tender?

It’s all in the marinade. The lime juice and avocado oil help to break down the steak fibers, and allow it to become more tender. Quick cooking and high heat searing at the end by broiling will help you keep from eating shoe leather. 

When you cut either flank steak or skirt steak, you will want to cut AGAINST the grain as well. The grain is the long strands of fibers that you can see running through the meat. Cutting against them will make the meat far easier to chew, as half the work of breaking them down is done.
