Bonus: this meal is super budget friendly thanks to the cheaper cut of steak that is flat-iron steak. Flat iron steak comes from the chuck region of the meat, so it’s inexpensive, yet becomes incredibly tender and flavorful on the grill. They have so much meaty flavor and a delicious juicy texture. Win!

Marinate the Steak for Grilled Flat Iron Fajitas

 

First, we need to marinate the steak, because we want to infuse it with tons of killer flavor.

 

So, in a large food-safe bowl, mix together soy sauce, jalapeño lime pilsner rub, chipotle paste, chopped cilantro, lime juice, orange juice, and canola oil. 

 

Add your 2-3 whole flat iron steaks to the marinade. Make sure the meat is completely submerged so we get the perfect amount of flavor all around. Cover and place the bowl in the fridge overnight or for a minimum of 4 hours. The longer the better. Great Grilled Flat Iron Fajitas start with a long marinade.

 

You Go Grill!

 

Next, let’s get cooking!

First, the steak. Preheat your grill to a medium-high temperature of about 350ºF for direct cooking. Add the marinated steaks onto the hot grill and cook for 4-5 minutes on each side. I like to cook them to a medium-rare temperature of 120ºF. Use a meat thermometer to check that they’re good to go, then pull your steaks off the grill. Set them aside to rest for 12 minutes to give the flavor and moisture time to settle back into the meat.

Prep the Veggies for Grilled Flat Iron Fajitas

 

Next up, the veggies! Slice 4-6 bell peppers and 1 red onion lengthwise. I like to use a variety of peppers so my meal looks nice and colorful. It tastes great either way! 

 

Add a cast-iron skillet or large plancha to the fire, drizzle with oil, and heat for a minute or so. Add the sliced veggies onto the pan and season generously with your favorite veggie seasoning. I like Jalapeño Lime Pilsner seasoning!

Cook the veggies until they’re softened to your liking, then pull them off the heat and get ready to put together your Grilled Flat Iron Fajitas.

 

Assemble and Serve

 

Before assemble your steak fajitas, slice the steak up into bite-sized pieces. Remember to do so against the grain so you get the best tender texture!

Top the hot veggies off with sliced steak, then finish the mix off with the garnishes of your choice. I love a sprinkle of cotija cheese, freshly chopped cilantro, and a squeeze of fresh lime juice.

 

Serve with warm tortillas and, of course, more cheese, cilantro, and lime wedges.
