Grilled Flank Steak Fajita Recipe

I live with a carnivore. The hubby loves meat and especially beef. Luckily there are so many lean cuts of beef that can be transformed into a healthy main dish.  So Bill gets his meat and I get a well-rounded meal.

To amp up the flavor when using a leaner cut, like with this easy beef fajitas recipe, I often mix up a quick marinade, add the beef and let it sit overnight in the fridge.  Unlike other proteins, beef can hold up to a longer marinating time which ensures more flavor penetration.

With flank steak, I also score the exterior with a sharp knife, to assist with osmosis. Then when it comes time for dinner, all the hubby has to do is toss the meat on the grill and cook to perfection.

What are Fajitas?

The term fajitas translates to little sash, a Spanish word for tiny belt, sash or band. Fajitas were first made of strips of skirt steak, cut across the grain and mixed with a fajita marinade, then grilled. Then they’re served in corn or flour tortillas. Plus the meat is generally paired with both onions and peppers.

How to Make This Easy Steak Fajita Recipe

As long as it’s grilling weather, fajitas frequently appear on our menu. And grilling season only dies when there’s a foot of snow on our Green Egg and/or subzero temperatures! Yes, the man in charge of the grill is not always rational!

Having a marinated flank steak parked in the fridge makes dinner time a breeze. The night before or the morning of the day you’re planning to serve these fajitas, mix up the simple fajita marinade and add the beef. Beef can take a longer marinade time than fish or chicken.

PRO-Tip: I use a gallon Ziploc bag to marinate the beef. It makes it easy to flip and agitate.

While the grill heats up,  saute some onions and peppers, cut up a few tomatoes and avocado, and pull out some guacamole, salsa, and sour cream. Choose whatever toppings tickle your fancy. I use a whole grain tortilla and pile on the veggies plus a few slices of beef. The hubby goes heavier on the beef, as a true carnivore would, and prefers a traditional flour tortilla.

Don’t forget beef like these easy beef fajitas when you’re planning a healthy meal. Just round out the meal with loads of veggies and some whole grains. Even my picky husband is satisfied with this formula.

  1. Hello Lizzy! Fajitas is one of my regular orders when I eat at Chilis. Well, it’s great that you make this at home. I should do that too!

  2. I love that you can use such a lean cut of beef for fajitas. And I’m always going to chose wholesale tortillas as I’m not a fan of the plain white ones. Great recipe, thank you for sharing. Sammie

  10. Lizzy,
    The hubby and I love, I mean really love, fajitas. I’ve never made them at home but I have to try this recipe.

  11. Liz this looks absolutely delicious. Do you know you’re the reason I love flank steak so much. We never ate it growing up and it used to be really hard to find here in Canada. They label things differently here and some cuts aren’t as popular here for some weird reason. I finally found it after reading one of your blog posts years ago. I found it at Costco of all places. We’ve been hooked on it every since. So thank you for introducing me to it. It’s quickly become one of our favourites.

    Now I’m craving fajitas.

  12. We love beef fajitas as well. Like Bill, my husband could eat beef every night. Your platter looks beautiful! Isn’t it amazing how just the simple marinade of lime juice and olive oil can transform beef into an incredibly tasty dish? This looks wonderful.

  13. Fajitas are a favourite over here too but we always choose chicken. I’m going to try beef next time because we love steak.

  14. Steak! Anything with steak is really good 😀

  29. This is such a tasty looking platter of deliciousness. There is nothing better than perfectly cooked beef and fajitas!

  30. If fajitas are on the menu, I always order them but I rarely make them at home. I think maybe twice in my life. I don’t know why and now that’s what I want for dinner tomorrow so thanks for sorting that out for me. 🙂

  31. My son and hubby would do a definite happy dance for this meal. 🙂

  32. Order for two, please and thank you!

  37. Those Fajitas look like perfection! They would be well received over here. This would be a fabulous RVing dinner too. Need to try out your marinade recipe.

  38. Dear Liz, we also love Fajitas around here and with all those lovely, colorful additions, we would really have a feast day!

  39. This is pretty much how I make fajitas! I love the lime, cumin, and salt marinade.  I usually squeeze some lime into the vegetables after I’ve sautéed them as well. The fun part is all the goodies you get to serve with them. They always come to mind if I’m having lots of people over, cause it’s so easy to put everything out and have a fajita buffet!

  40. What a gorgeous platter to put in the center of the table. Something for everyone, plus healthy and delicious! I’m in!

  41. This should be dinner tonight and leftovers tomorrow. I’ve had flank steak in the freezer for almost 2 months. Shame on me!!! Hopefully, it still good and I can make these for the weekend.
