How To Make Steak Fajitas
- Make the Marinade: Whisk olive oil, lime juice, cilantro, garlic, brown sugar, chili flakes, cumin, and salt until well combined. Pour half into a shallow dish and refrigerate the rest to use later.
- Marinate the Steak: Place the steak in the marinade, turning to coat evenly. Cover and refrigerate for at least 30 minutes or up to overnight, then remove 30 minutes before cooking.
- Cook on Skillet: Heat teaspoon of oil in a grill pan or cast-iron skillet over medium-high heat. Sear the steak for about 4 minutes per side, then let it rest for 5 minutes.
- Cook on Grill: Preheat your barbecue or outdoor grill to high heat. Grill the steak for 5–7 minutes per side, then transfer to a plate and rest for 5–10 minutes.
- Sauté the Vegetables: Wipe down the skillet or grill, add a drizzle of oil, and cook the peppers and onions with half of the reserved marinade until tender and slightly charred.
- Assemble the Fajitas: Slice the steak thinly against the grain. Fill warm tortillas with steak, vegetables, avocado, cilantro, and sour cream, then drizzle with the remaining marinade.
A hearty side like Warm Chicken and Pumpkin Lentil Stew is perfect for rounding out your fajita night. Its cozy flavors pair beautifully with the zesty chili lime steak, giving you a filling, comforting balance.
For something lighter, Simple Lemon Garlic Asparagus brings a fresh, crisp contrast, while Honey Roasted Butternut Squash & Brussels Sprouts With Bacon adds caramelized sweetness and savory crunch to the table. Together, these sides create a well-rounded spread that makes your steak fajitas shine even brighter.

All I can say is YUM..made it tonight for the first time, and going forward, this will be the only way I marinate steak for fajitas. I left the steak in their for about 2 hours, brought it out of the fridge 30 minutes before I was going to put it on my grill..
This marinade is so simple and delicious. I’ve cooked both the chicken and steak fajitas with it and it makes the meat so succulent and delicious. It’s such a simple stress-free meal too. I’ve cooked it for visitors and they loved it. I recommend this site to everyone.
The marinade was SO GOOD! I only marinated the meat for a half hour, but it had incredible flavor. This will definitely be going into our weeknight rotation.
This is hands down the BEST fajitas recipe I’ve ever made. We have been using this in our weekly rotation for over two years now and it is one of our favorite meals!
Fabulous! Marinated a flank steak for about five hours and grilled. Excellent flavor and adding some of the reserved marinade to the peppers and onions just brings it all together. Served with homemade corn tortillas. Will definitely be making again!
Excellent marinade – the meal was so good! Thanks for the great recipe. Definitely a keeper.
This recipe is SOOOO good that we actually prefer it to any restaurant fajita we’ve ever had. I get requests from my college kids to make this when they come home! The recipe is definitely a home run!
Great recipe! My hubby is the pickiest eater on the planet and he loved these fajitas! I had to leave out the avocado slices because of his narrow taste profile but they didn’t go to waste. I dispatched them in the kitchen. I wouldn’t change anything about the recipe and plan to slot it into weekly rotation here. Thank you, Chef!
We had these last night with both corn and wheat tortillas, and they were a huge hit. Delicious! Thanks, so much!
