Sizzling steak fajitas always hit the spot for an easy, delicious, and exciting dinner. Just don’t forget to prep some tortillas, salsa, and guacamole for the ultimate fiesta night!
Making steak fajitas is one of my favorite summertime rituals. I love heating the grill, having friends over, and drinking a classic margarita (or strawberry margarita). It’s always a fun time! But if you don’t have an outdoor grill there’s no need to fret, you can also make this recipe on an indoor grill pan for the best weeknight dinner.
I’m a fajita lover through and through (have you tried my chicken fajitas or shrimp fajitas?). But the marinade for this steak fajitas recipe is what makes it so special. It’s tangy with the perfect amount of spice, and gently tenderizes the meat, setting it up for ultimate success on the grill.
Steak Fajitas Ingredients
Good news, the ingredient list is super simple and not at all complicated. Here’s what you’ll need:
- Steak: Flank steak is what’s typically used for steak fajitas. But you can also use sirloin steak or skirt steak (similar to my carne asada recipe).
- Steak Fajita Marinade: A simple yet flavorful combo of lime juice, olive oil, garlic, ground cumin, chili powder, cayenne pepper, salt, and pepper — that’s it!
- Vegetables: Grab a white or yellow onion and a couple of bell peppers to complete the skillet! I like to use a mix of red, green, and yellow peppers for extra color.

How To Make Steak Fajitas
If you don’t have an outdoor grill, I love to use this indoor grill pan right on my stovetop! Once that’s set up, here’s how easily these steak fajitas come together.
Marinate. Stir together the marinade ingredients. Then add the steak, toss to combine, and marinate for 1 to 4 hours. Try not to exceed 4 hours as your steak can become a bit chewy after that from the lime juice!
Grill the steak. Grill the steak for 3 to 4 minutes on each side, or to your preferred level of doneness. Then remove the steak to a cutting board to let it rest for a few minutes.
Cook the veggies. While the steak rests, sauté the onion and bell pepper slices for 4 to 5 minutes.
Slice the steak. When the onion and bell peppers are just about done, slice the steak into long, diagonal strips. Remember to slice against the grain for perfectly tender pieces!
Cook everything together. Add the steak back to the skillet, and stir it together with the veggies. That’s it!
Ways To Serve Steak Fajitas
But you could also turn this into a plate or bowl with cilantro lime rice (or Mexican rice) and all the Mexican toppings you love. I also highly recommend a drizzle of lime crema or chipotle sauce on top!
- To store for the week: Let the fajitas come to room temperature before placing leftovers in an airtight container. Then, store it in the fridge for 4 to 5 days.
- Freeze for later: Steak fajitas will keep for up to 3 months in an airtight container the freezer. Perfect for an easy weeknight reheat!
- To reheat: Let thaw in the fridge overnight, if frozen. Then microwave for 1 to 2 minutes until it’s warmed through.
