Steak Fajitas on the grill

What type of steak is best for fajitas?

I like to use flank steak for my fajitas, but skirt steak would also work. To help tenderize the meat, I pierce the steak with a fork and then season it for at least a few hours or up to 24 hours before grilling. I used cumin, crushed garlic, scallions, salt, and pepper for seasoning.

What to Serve with Beef Fajitas

Below are some topping and side dish ideas to serve with your fajitas.

Toppings: Mexican-style cheese, sour cream, sliced avocado or guacamole, pico de gallo
Corn: Warm Mexican Corn Salad, Grilled Corn Salad with Feta, Corn Tomato Avocado Salad
Rice: Mexican Brown Rice, Cilantro Lime Rice, Fiesta Lime Rice
Beans: Southwestern Black Bean Salad, Instant Pot Black Beans, Instant Pot Refried Beans
Salsa: Serve any of these with your favorite tortilla chips – Easy No-Cook Salsa, Salsa Verde, Avocado and Mango Salsa


  • Swap the flank steak for skirt steak.
  • If you don’t have an outdoor grill, you can broil the meat in the oven or cook on the stove.
  • Serve the steak, peppers, and onions over chopped romaine for a fajita salad. Squeeze with lime juice or top with salsa for a simple dressing.

These grilled steak fajitas are easy enough to make as a weeknight meal, or fun to create a theme party and serve up all your favorite Mexican appetizers.


  • 1 1/2 lbs flank steak, trimmed
  • 3 cloves garlic, crushed
  • 1 tbsp cumin, or to taste
  • 2 scallions, sliced (optional)
  • salt + fresh pepper, to taste

For The Onions and Peppers

  • 3 medium onions, sliced into long strips
  • 3 bell peppers, I used multi-colors, sliced into strips
  • 1 tbsp olive oil
  • salt + fresh pepper , to taste
  • 12 6-inch flour or corn tortillas


  • (I like to season the steak a few hours ahead.) Pierce steak with a fork all over to tenderize. Season steak with cumin, garlic, scallions, salt and pepper. Allow steak to rest at room temp at least 10 minutes before grilling.
  • In a large grill-safe pan such as a clay Chamba or cast iron skillet combine onions, peppers, olive oil, salt and pepper. Toss well to coat.
  • Place on the BBQ and cook on medium-low heat, tossing occasionally until onions are caramelized, about 20 minutes. This could also be cooked inside on the stove as well.
  • When the onions and peppers are done, set aside to keep warm on the top rack of your grill; raise the flame of the grill to high flame.
  • Discard scallion and sear steak 4-6 minutes without moving, turn the steak over and cook a few more minutes until rare or medium rare (well done will be too tough). Remove from grill and let it rest a few minutes before cutting.
  • Cut meat into 1/4 inch thin slices and combine with the cooked onions and peppers and serve with tortillas, cheese, guacamole and sour cream.

  1. Looks great – going to try it – FYI – the pots are no longer available

  2. This was tasty. I marinaded the steak for 8 hours and added two tablespoons of lime juice. I served pineapple as a side. Yum!

  3. Husband and I loved these fajitas. Only changes we made were using all green peppers instead of multi.-colors and thinly slicing the meat. Will definitely make again. A very fresh tasting recipe; great with fresh pineapple as a side.

  4. As a Texan who eats a lot of TexMex, I can tell you that These have no flavor. Just marinate with low cal Italian dressing for a couple of hours. You’ll be much happier.  I love almost everything else on this site. I was very disappointed that I wasted a good cut of meat on this recipe 🙁

    • Try adding a hot pepper or two to the pepper mix. Salad dressing adds unnecessary calories and chemicals.

  5. I love everything I make from here. …you're an amazing inspiration. …I was curious if any of these beef recipes can sub flat iron cut. ..or if you have any recipes involving that cut

  6. I made this tonight with extra steak that I had from your Chimichurri Steak recipe (awesome) and the Mexican Corn Salad…my husband told me afterwards that he loved me 🙂 These fajitas were amazing as well. I did add some Mexican oregano that I had left over from another one of your recipes. Awesome per usual 🙂

  7. There is lots of snow outside…so cooking on the grill isn't really an option. I want to make these for dinner. Can I cook steak on the stove in a non-stick frying pan? Don't have a cast iron.

  8. I LOVE your recipes! Can't wait to try some. I am trying to figure out how to add recipes to my recipe box. Can anyone help with that?

  9. Since they were out of flank steak, my butcher recommended beef sirloin flap meat which was less expensive and equally delicious. Instead of adding sour cream and cheese I added a few thin slices of avocado and a half teaspoon of pico de gallo. My husband and I agree this is our new favorite and plan to take it camping with us this weekend! THANKS SO MUCH FOR YOUR YUMMY CREATIONS!

  10. Can you use pre-cut meat for this? If so, would you heat it up with the peppers and onions the same?

  11. Thank You, Thank You, Thank You!!! My daughter found you and for the past couple weeks, we've been using your recipes DAILY!! It goes GREAT with our new exercise regime 🙂 Sincerely, Thank You!!!!

  12. I made it with chicken and was great. Just put a little bbq sauce. Me encanto. Gracias.

  13. Dana, sure or you can even broil them in your oven.

  14. Any adjustments for indoor cooking? Can I just sear the meat on high heat on my stove? I don't do outside grilling. 🙂

  15. Making these tonight for Cinco de Mayo they look delish

  16. You are the best! Everyone enjoys your delightful dishes…………….

  17. Bianca – Great idea, 197 calories without the tortillas per serving. Since you are not eating the tortilla you might want larger portions though.

  18. I love tortillas… I still have leftovers so I am going to try your recipe tonight for dinner! Thanks dear!

  19. Hey Gina!

    I was wondering what the calories would be without the tortilla? I wanted to make it into a salad!

    I love all your recipes! You're site has definitely turned me into a healthier eater!

  20. Looks so good! YUM!

    Homeowner Insurance

  21. Yes they sell them at Stop and Shop and Pathmark.

  22. Gina Question do you get those Tortillas tell me you get them local somewhere in L.I 🙂 I went looking for them at T.J's but don't see them.. sigh… Thanks darling. You just posted my Friday Night dinner!

  23. Thanks Angela, I will adjust!

  24. Gina, these look amazing! You listed 6 tortillas in the ingredients, but would it be 12 tortillas total if the serving size is 2? Just checking.

    Maybe I'll ask my husband to make these for Mother's Day!!

  25. I think I love every one of your recipes, we have the same taste in food! This is no exception, flank steak on the grill is the BEST way to go!

  26. Christina, based on the smaller ones.

    I also have chicken and shrimp fajitas posted in my older recipes.

  27. Gosh that looks good! Makes me want to run home and pick up all those ingredients asap!
    – Brittany

  28. I don't eat red meat, but I bet these would be great using grilled chicken as well! I love fajitas!

  29. YUM! I'd love to have these tomorrow, but thinking of going the shrimp route.

    The meat looks so tender and the perfect "rare-ness" 😉

  30. Looks wonderful!!!

    Are you basing the calorie count on the smaller sized tortillas or a larger sized?

  31. I was just craving steak fajitas from my local Mexican restaurant! I think I will stay in now and save some points! Thanks!
