What's the Secret to Amazing Flavorful Steak Fajitas?
There are three things that make steak fajitas amazing.
1. The marinade. For fajitas, it's important that the marinade has lime juice in it, for that signature tangy flavor. I recommend marinating your steak for at least 2 hours, or overnight. However, I know we can forget or be in a time crunch. In that case, try to marinate for at least 30 minutes to still get the flavors into that meat!
2. The cooking and cutting of the steak. Cooking steak is probably one of the easiest things you'll ever do. You just need a hot surface, and to flip it after about 3 minutes. Cook the steak as a whole piece of meat and then cut it to keep it juicy.
When you cut the meat, be sure you're cutting against the grain. Meat has long fiber-looking tissue. When you shred meat or a roast falls apart, it almost always happens with the grain.
To make tender fajitas, you want to cut it the opposite way, against the grain for a truly melt-in-your-mouth bite of juicy tender steak.
3. The absolutely necessary finishing touch on every fajita should be a final squirt of lime juice when the steak is done cooking. It makes the dish. I'm not kidding.
You can do this yourself, right in the skillet, and then give everything a little toss. Or you can serve your fajitas or toppings bar with lime wedges to let everyone add as much lime as they want.
What Kind of Steak Do You Use for Fajitas?
Skirt and flank steak are the two most popular choices for fajitas. In this recipe (pictures and video), I've used skirt steak. It's probably the more traditional of the two, and it's also very forgiving, staying very tender, even if it's over-cooked a bit.
Flank steak is a slightly leaner cut of meat and is best cooked on the rarer side, but it also works great in fajitas as long as you're super aware of cook times!
What to Serve with Steak Fajitas
This recipe already has a veggie side, as it includes bell peppers and onions. It's one of the reasons that skirt steak fajitas make such a quick and easy dinner!
Serve them up with some fresh made flour tortillas or corn tortillas for your carb, and you're all set! Of course, you can also store bought tortillas, but I prefer my fresh recipes when I have the time to make them!
If you're looking for a low carb option for fajitas, you can use lettuce leaves as a wrap or serve it straight on a bed of greens. Delicious both ways!
If you're looking for a little more filling, we love this copycat Chipotle Cilantro Lime Rice. It's fresh and zesty. Plus, it's super easy to make and goes perfectly with fajitas!
How should you cook your steak?
Medium-rare is recommended. The 3-4 minutes on each side, as in the recipe, is probably closer to the medium than rare. I, personally, love my steak as rare as can be, but still cooked (also seen in the video).
But of course, you're the cook! So cook to your personal preferences. Increase the cook time for a more well-done steak, or decrease it for rare.

- Prick your skirt steak with a fork multiple times before marinating. This will allow the marinade to really soak into the meat and give it so much extra tangy flavor.
