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.
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, then grilled. Then they’re served in corn or flour tortillas. Plus the meat is generally paired with both onions and peppers.
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, gucamole or sliced avocados, sour cream, minced cilantro, and jalapenos or pickled jalapenos.
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.
