¼ cup soy sauce
¼ cup fresh lime juice
2 tbsp brown sugar
1 tsp ground cumin
1 tsp chili powder
½ tsp kosher salt
½ tsp freshly ground black pepper

1 red bell pepper, sliced
1 yellow pepper, sliced
1 green pepper, sliced

How To Make Grilled Flank Steak Fajitas: Step-by-Step

Okay, let’s get down to the nitty-gritty. Here’s how we turn these ingredients into a fajita feast:

Marinate the Steak: Place the flank steak in a large resealable plastic bag. For the marinade, in a small bowl whisk olive oil, soy sauce, lime juice, brown sugar, cumin, chili powder, salt and pepper. Reserve ¼ cup marinade and pour remaining marinade over flank steak, seal bag and refrigerate at least 2 hours or overnight. The longer it marinates, the more flavorful it becomes!
Prep the Veggies: While the flank steak marinates, combine sliced peppers and onions with remaining ¼ cup marinade. Refrigerate until ready to cook. This allows the veggies to soak up some of that delicious marinade flavor.
Grill the Steak: Allow flank steak come to room temperature before cooking. When ready to cook, preheat grill to medium-high heat and lightly oil grill grates. Remove meat from marinade and place on grill. Grill 6 minutes, flip and cook 5 minutes more until cooked through. For medium-rare, you’ll want to cook until it reaches an internal temperature of 130-135°F.
Rest the Steak: Transfer meat to a cutting board and let rest 10 minutes. This is crucial! Resting allows the juices to redistribute, resulting in a more tender and flavorful steak.
Cook the Veggies: Heat a large skillet over high heat and add pepper and onion mixture. Cook 5 minutes, until peppers and onions are slightly charred. Remove from skillet and set aside. The char adds a lovely smoky flavor.
Assemble the Fajitas: When ready to assemble, thinly slice flank steak against the grain. Place steak down the centre of each tortilla, top with pepper and onion mixture followed by sliced avocado, salsa and parsley. Roll tortilla and serve immediately.

And there you have it! Easy peasy, right? Now, let’s talk about some pro tips to take these fajitas to the next level.

Pro Tips for Perfect Grilled Flank Steak Fajitas

Alright, friend, let’s elevate these fajitas from good to *amazing* with a few insider tips:

Marinate, Marinate, Marinate: Seriously, don’t skimp on the marinating time. The longer the flank steak sits in that flavorful concoction, the more tender and delicious it will be. Overnight is ideal, but at least 2 hours will do in a pinch.
Room Temperature is Key: Before grilling, let the flank steak sit at room temperature for about 30 minutes. This helps it cook more evenly.
Hot Grill is a Must: Make sure your grill is nice and hot before you throw the steak on. This will give you a beautiful sear and lock in those juices.
Don’t Overcook: Flank steak is best served medium-rare to medium. Overcooking will result in a tough, chewy steak. Use a meat thermometer to ensure it’s cooked to perfection.
Slice Against the Grain: This is crucial for tender fajitas. Look for the direction of the muscle fibers and slice perpendicular to them.
Warm Your Tortillas: Nobody wants a cold, stiff tortilla. Warm them up in a dry skillet or microwave for a few seconds before serving.
Get Creative with Toppings: Don’t be afraid to experiment with different toppings! Sour cream, guacamole, cheese, pickled onions, and jalapeños are all great options.

Remember, cooking is all about experimenting and having fun. Don’t be afraid to put your own spin on things!

Common Mistakes to Avoid When Making Flank Steak Fajitas

We all make mistakes in the kitchen, it’s part of the learning process. But here are a few common pitfalls to watch out for when making flank steak fajitas:

Not Marinating Long Enough: This is the biggest mistake! The marinade is what gives the flank steak its flavor and tenderness. Don’t rush it.
Overcooking the Steak: Flank steak is a lean cut of meat, so it can easily become tough if overcooked. Use a meat thermometer and aim for medium-rare to medium.
Not Resting the Steak: Resting allows the juices to redistribute, resulting in a more tender and flavorful steak. Don’t skip this step!
Slicing with the Grain: This will result in tough, chewy fajitas. Always slice against the grain.
Using Cold Tortillas: Warm tortillas are essential for a good fajita experience.

Learn from these mistakes, and you’ll be well on your way to fajita perfection!

Flavor Variations for Your Flank Steak Fajitas

One of the best things about fajitas is how versatile they are. Here are a few fun variations to try:

Spicy Fajitas: Add a pinch of cayenne pepper to the marinade or top with sliced jalapeños for some extra heat.
Citrusy Fajitas: Add the zest of one lime and one orange to the marinade for a bright, citrusy flavor.
Smoky Fajitas: Use smoked paprika in the marinade for a smoky flavor. Grill the peppers and onions over wood chips for an even smokier flavor.
Mushroom Fajitas: Add sliced mushrooms to the pepper and onion mixture for a vegetarian option.
Pineapple Fajitas: Grill some pineapple slices and add them to the fajitas for a sweet and tangy twist.

The possibilities are endless! Don’t be afraid to get creative and experiment with different flavors and ingredients.
