Why You Must Make
- This recipe is perfect for carnivores and beef lovers like my hubby.
- The marinade infuses into the beef and adds flavor along with tenderizing.
- Just toss on the grill, prep the toppings, and a delicious dinner will be ready in no time!
How to Make
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!
- While the grill heats up, saute some onions and peppers.
- Grill your beef to your desired doneness. We prefer medium rare.
- Let your beef rest, covered with foil, for 10 minutes to let the juices redistribute before slicing.
- Also, cut up a few tomatoes and avocados, and pull out some guacamole, salsa, and sour cream. Choose whatever toppings tickle your fancy.
- Offer flour, corn, or whole grain tortillas 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 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.
- PRO-Tip: I use a gallon Ziploc bag to marinate the beef. It makes it easy to flip and agitate.
- You can make and marinate the night before. Beef will stand up to a longer marinating time than chicken or seafood.
- But if beef is not your thing, this marinade can be used for chicken, too. But don’t marinate it as long as beef. Six hours is good for chicken.
- Use your favorite taco or fajita toppings.
- For even more flavor, rub spices on your flank steak before marinating.
- PRO-Tip: Cut your beef slices across the grain. This means from one long side to the other. This makes more tender slices than slicing in the other direction.
- If you have access to freshly made tortillas, they’ll make your fajitas even better!
Frequently Asked Questions
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, grilled, then served in corn or flour tortillas. The meat is generally paired with both onions and peppers.
Skirt steak is classic, but flank steak works well, too.
The marinade should contain acid which will tenderize the beef by breaking down some of the strands of protein. Lime juice is classic, but the marinade should also have garlic, oil, and spices along with some heat from red pepper or jalapenos.
Cooked bell peppers and onions are standard, but there are a few other toppings to consider. Here are some more ideas: cheese, salsa or pico de gallo, guacamole or sliced avocados, sour cream, minced cilantro, and jalapenos or pickled jalapenos.
Leftovers keep for 3-4 days in the refrigerator if kept in an airtight container. You can freeze leftovers for up to 3 months.

Totally yummy! I love a good plate of fajitas. This looks like it’d make some amazing fajitas, or even a great fajita salad! Love how tender the beef looks!
I love Fajitas, Liz. And homemade are the best. This looks so delicious. I will try it sometime!
Haha! I live with a carnivore too. Looks good, Liz! Have a great weekend, my friend.
Great idea for a fast and easy dinner!
Sounds like a great dinner to me, I think flank is a slightly cheaper cut too which is great!
Steak! Anything with steak is really good 😀
Fajitas are a favourite over here too but we always choose chicken. I’m going to try beef next time because we love steak.
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.
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.
The hubby and I love, I mean really love, fajitas. I’ve never made them at home but I have to try this recipe.
My husband loves the BBQ as well and while we don’t get snow, we do get rain. He goes outside to BBQ with the tongs in one hand and a golf umbrella in the other. I do like the sound of your marinated steaks with all the vegetables for the fajitas xx
My husband is a big meat eater too. He’d love these.
This is what I want for dinner tonight. Looks Great!
Yes to all of this Liz, perfect!
The beef looks so tender and juicy. A great dinner!
I’m ready to fire up the grill to make these. Yummy!
This is my kind of dinner! I love fajitas, and your marinade sounds so flavorful!
Fajitas are always a favorite Liz! Keep that grill going:@)
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
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!
