Great Steak Fajitas Recipe for Summertime Grilling

One of the best ways to enjoy summertime grilling on your porch is to make this great Steak Fajitas recipe. This is a quick-cooking main dish for lunch or dinner that is a definite crowd-pleaser.

This Steak Fajitas recipe is great for a quick supper on weeknights. It is even better to enjoy it on a leisurely weekend for a celebration with friends.

You start the night before by marinating the flank steak which saves prep time when you make dinner. Also, by cooking the steak on the grill you’ll keep the heat out of the kitchen!

Meal Prep for the Great Steak Fajitas Recipe

Sizzling flank steak on a charcoal grill
  • The night before, slice the peppers and onions and put them in a sealable bag or container with a lid.
  • Lightly score the meat across the grain. Or, jab a fork into the steak all over the surface. A little tenderizing if you will. Then, rub the steak all over with store-bought fajitas seasoning. Or, better yet, make your own homemade smoky fajita seasoning (see below).
  • Place the steak in another resealable bag and add the beer. Try to squeeze out as much air as possible before sealing the bag. This keeps the liquid in contact with the steak.
  • Next, put it all in the fridge and let the steak marinate overnight!
  • Let the steak rest for 30 – 45 minutes on your kitchen counter before grilling. And be sure to let it rest after removing it from the heat as well.

What is a good marinade for beef fajitas?

A dark beer or Mexican beer such as Negra Modelo is a great liquid for the marinade. Also, I add fajita spices to my steak before marinating it in the beer.

I have also been known to marinate the steak in red wine with the fajita spices. Delish either way!

What is the best steak for fajitas?

Flank Steak is recommended for this recipe

Flank, Flank Baby!

Flank steak is usually recommended and is my personal favorite. It is a leaner cut of meat which I cook medium-rare.

Additionally, some recommend using skirt steak. Either could work. It might just depend on what is on sale in your grocer’s meat department?

What are the ingredients for this recipe?

  • One 2 – 3 pound flank steak
  • Mexican beer such as Negra Modelo
  • Fajita seasoning (see recipe above)
  • Large Onion
  • Red or orange bell pepper
  • Green bell pepper
  • Poblano peppers or Jalapeno peppers if you like more heat
  • Olive oil
  • Spices such as cumin and chili powder
  • Serve the sliced steak in flour or corn tortillas

How do you make the Great Steak Fajitas recipe?

Get ready for some delish summertime grilling!

To begin, rub the flank steak down with fajita seasoning either storebought or homemade.  Then, put the steak in a gallon Ziploc bag and add the beer. Marinate the flank steak overnight.

Take it out of the refrigerator and let it rest for about 30 – 45 minutes. Remove the steak from the marinade and put it on the grill.

Cook until the internal temperature comes to 130°F for medium-rare.  About 4 – 5 minutes each side. The steak will climb another five or so degrees when it rests.

If you prefer rare steak, shoot for 125°F and 145°F for medium.

How do you cook the steak?

Another way to cook steak fajitas is in the oven on a sheetpan

My favorite way to cook the steak is to season, marinate, and grill the steak on a charcoal grill.  Otherwise, you can cook the beef in the oven, but to me, it just isn’t the same without that smokey char from the grill.

Sheet pan recipes abound for steak fajitas and some other recipes call for a crockpot. Just so you know, by using these methods you’ll miss out on that great smoky flavor that only a barbeque grill can provide.

You can cook the steak in a cast iron skillet as well. Again, no smoky flavor, but it does give a nice char to the meat.

How do you cut flank steak for fajitas?

Most importantly, you should tent the steak with foil and let it rest for at least 15 minutes before slicing. Additionally, when you slice the flank steak, make sure you cut diagonally across the grain. Also, keep the slices on the thin side about ¼ – ½ inch thick.  Otherwise, you will have tough and stringy-looking slices.
