I have absolutely no idea why or how I have not shared a Beef Fajitas recipe in the past here on $5 Dinners! One, because I LOVE them and order them often when we go out for TexMex. Two, because they are so delicious and beef fajita meat is an inexpensive cut of meat. Three, because I want you to make them using meat, your own marinade and slicing them yourself.
(I know you can get the pre-marinated kind that are already cut up, but grilling the meat whole and slicing is so much tastier! And so is slicing fresh bell peppers and grilling them in a veggie basket, alongside the meat!)
How to Slice Beef Fajitas
The key to getting the perfect beef fajita slices is to cut ‘across or against the grain’ of the meat, as I show and explain in the video.
If you slice ‘with the grain,’ then the meat is really tough and when you bite into the tortilla and beef, you’ll end up chewing and chewing and chewing. When you slice ‘across the grain’ the meat will ‘fall apart’ easily as you take each bite and won’t be challenging to chew at all!
So know that you know how to properly slice beef fajitas.
(Note: My grocery store sells the ‘beef for fajitas’ package. If your store doesn’t offer that, you can use skirt steak or even flank steak. You can also ask if they will tenderize it for you, that will help make it ‘softer’ too!)
The key to crazy delicious beef fajitas is letting them marinate a long time (overnight, ideally!) in the lime juice and spices, as the lime juice will help tenderize them before you grill them.
