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.

Hi Karina. I know I emailed you earlier about someone stealing this from you but I thought to message you here! I don’t know if it’s of your concern but please email me so I can send you the information I have.
Hi Brenda,
Thank you so much for letting me know! I will look through my emails and reply back. I apologize for the delay. Thank you for looking out for me!
XO, Karina
The marinade is to die for! I’ve been making this fajita recipe almost every week for a couple of months. I double the marinade so I have plenty to put on the frying veggies. We sometimes have veggies left over, and we could lick the plate! Thanks for a great recipe!
That is a great idea and so helpful to know! Thank you so much for sharing and following along with me! XO
My husband and I really enjoyed this so much! The only issue we had was that I got the wrong cut of beef and it was totally tough. Besides user error, it was amazing! Thank you!
What kind of steak and how much?
I like to use flank steak, rump or skirt steak. I usually use about 1 pound. Hope that helps! Enjoy your fajitas!
I second another person’s opinion that these are not only the best fajitas I’ve ever made, they are the best fajitas I have ever tasted ANYWHERE! Tomorrow is Cinco de Mayo, so this is a great excuse to make them yet again (like I really need an excuse!). Truly, thank you from the bottom of my heart for this recipe – I love it SO much!
Tried it loved it! Only thing I added was an avocado sauce.
