How To Cook Steak Fajitas

Remove your steak from the fridge and pull out of the ziplock bag.
Heat a large cast-iron skillet over medium-high heat, and add your cooking oil. Once the oil is hot, add about half of the steak, being careful not to overcrowd the pan. You’ll probably need to cook the meat in 2 batches. Season with garlic salt on both sides while cooking.
Saute the steak on each side for about 3 minutes, or until the desired doneness is reached. You can use a meat thermometer to determine the doneness of the meat (medium is an internal temperature of about 130-135 degrees).
Once cooked, remove the steak from the pan and let rest in a dish or on a cutting board tented with aluminum foil for 5 minutes before slicing. Repeat with remaining meat.
While the meat is resting, add a couple more tablespoons of oil to the pan, then add the sliced bell peppers and onion. Season with garlic salt and let them sear for 1 minute before stirring, then stir every 90 seconds or so as the vegetables sear. Cook for about 6 minutes, or until slightly tender.
Cut the steak into thin strips against the grain of the meat. Serve in a warm tortilla with the sautéed veggies and your favorite fajita toppings. Enjoy!

Recipe Tips and Tricks

A cast iron skillet works best because of the way they conduct and hold heat, so if you have one, use it. If not, a regular skillet will work, or you can also grill your steak.
If you want to make this recipe gluten-free, use corn tortillas!
Make sure your fajita meat cut is against the grain! Cut your steak perpendicular to the grain of the meat. It helps to break up some of the tissue in the meat, making it even more tender.
These taste great reheated, so make a little extra and serve throughout the week over rice, in a salad, or even with eggs for breakfast.
Ziplock bags work great for marinating meat. Just add in your meat and marinade, and squeeze out any excess air. Pop it in the fridge and let it do its thing!

Frequently Asked Questions

What kind of steak for fajitas is best?

The most traditional cuts of steak for fajitas are skirt steak (very tender) and flank steak fajitas (slightly leaner, and best cooked to more of a medium-rare). But there really isn’t a bad steak option for fajitas.
Some of the more budget-friendly yet still can be the best steak for fajitas:

– Sirloin fajitas – more inexpensive and still nice and tender when thinly sliced.
– Tri-tip steak fajitas – cut from the bottom sirloin, tri-tip is full of flavor and stays juicy.
– Round steak fajitas – inexpensive and lean; it’s best to marinate this slightly longer.

How Much Steak Per Person?

If you’re wondering how much fajita meat per person, here’s a little guideline I like to keep in mind. Keep in mind that this is measured in raw meat.

-1/4 lb per person if you’re feeding kids or light eaters
-1/3 lb per person if you’re feeding average adults

What are the Best Vegetables for Fajitas?

Bell peppers and onions are the traditional veggies in fajitas, but you can use up whatever you have around. Try sliced mushrooms, zucchini, or if you like things spicy, slice a few extra jalapeños from your marinade and toss them in the skillet.

How do you warm tortillas?

Warming tortillas is simple! Just before serving, place tortillas on a paper towel in the microwave and cook on high for about 20 seconds. You can also warm them individually over your stovetop burner for 5-10 seconds per side, depending on how cooked you like them.

Wrap them loosely in a kitchen towel to keep warm.

What to serve with Beef Fajitas

Storing and Reheating

Refrigerator: store leftover Steak Fajitas in the fridge for up to 3 days.
To reheat on the Stovetop – heat a cast iron skillet over medium high heat, then toss in the steak and veggies that you want to reheat. If you have any leftover (and unused) marinade, add a couple tablespoons of that, too. Heat, tossing occasionally, until warmed through.
To reheat in the Microwave – transfer your steak and veggies to a microwave safe container and reheat on high for about 30 seconds at a time until heated through.
