What Are Flank Steak Fajitas?

First, if you’re unfamiliar with steak fajitas, you’re missing out. Think sizzling strips of meat and veggies, all nestled in a warm tortilla and topped with your favorite toppings. Yum. And when it comes to the meat, flank steak is the way to go. Flank steak is a cut of beef that comes from the abdominal muscles of the cow. It’s a lean cut with some serious flavor, and when cooked right, it’s tender and juicy. It’s got just the right amount of chewiness, and when sliced against the grain, it’s perfect for those thin strips that make fajitas so dang tasty.

How to Make Flank Steak Fajitas

Flank Steak Fajita Marinade

1. Combine the beer, garlic, and a heavy seasoning of salt and pepper in a small bowl. Pat the steak dry and place in a large resealable bag. Pour the marinade over, seal, and let rest in the fridge for 1 to 8 hours.

Flank Steak Fajitas

1. When ready to cook the fajita meat, preheat the grill to medium-high and clean grate.
2. Toss the veggies with 2 tablespoons of oil and season with salt and pepper. Arrange in a grill pan or with tongs. Then, grill until tender and slightly charred in spots.
3. Meanwhile, remove the steak from marinade and pat dry with paper towels. Coat in remaining 1 tablespoon of oil and grill 8 to 10 minutes flipping once halfway through.
4. Cover the steak with foil and allow to rest for 10 minutes before cutting into thin slices against the grain.
5. Serve sliced steak with charred veggies, pico de Gallo or fresh salsa, and other desired toppings.
6. You can also heat the tortillas over the grill while the steak rests if desired.

What to Serve With Grilled Steak Fajitas

Serve with warm tortillas and generous amounts of toppings! You can also turn your fajitas into Flank Steak Tacos or serve them with chips and make Carne Asada Nachos.

To round out this meal, consider serving them with grilled chicken fajitas, cilantro rice, and a hot skillet of rajas con crema.

Leftovers & Reheating

The best way to store your steak fajitas and veggies is in an airtight container in the refrigerator for up to 3 days. Although the veggies may be more wilted, they will still taste just as fabulous as the first time!

As for reheating, you can microwave your grilled chicken fajitas for 30-45 seconds with a damp paper towel on top to keep them juicy. If you have a little bit more time, try reheating it on a skillet for a few minutes until the fajitas are warm enough for your liking. Leftover grilled steak fajitas are perfect for making Carne Asada Fries for a fun twist on the leftovers.
