Ingredients

For the Marinade

1/3 C. fresh lime juice (about 4 limes)
2 T. soy sauce
1/2 t. red pepper flakes
2 green onions, thinly sliced (about 1/3 cup)
2 T. fresh ginger, minced

For the Steak

1-1/2 lb. flat iron steak
Vegetable oil for grates (or grill pan)
Coarse salt and fresh ground pepper to taste

How to Make Grilled Lime Flat Iron Steak

Step 1: Prepare the Marinade

Combine the lime juice, soy sauce, green onions, ginger, and red pepper flakes in a mixing bowl or directly in a resealable plastic bag.

Step 2: Score the Steak

Lightly score both sides of the flat iron steak in a cross-hatch pattern. This helps the marinade penetrate better.

Step 3: Marinate

Add the scored steak to your Ziplock bag with the marinade. Press out all air before sealing to ensure full flavor absorption. Marinate for at least 30 minutes or overnight in the refrigerator.

Step 4: Preheat Your Grill

Heat your outdoor grill, contact grill, or indoor grill pan to medium-high heat. Lightly oil the grill grates or pan to prevent sticking.

Step 5: Cook the Steak

Remove the steak from the marinade and discard any leftover liquid. Pat it dry with paper towels before seasoning with salt and pepper. Place it on the grill and cover; cook for about 6-8 minutes per side until you reach your desired doneness (medium-rare is recommended).

Step 6: Rest and Serve

Once cooked to your liking, let the steak rest for about 10 minutes before slicing thinly against the grain. Serve with sides like Cuban-Style Black Beans and Rice if desired. Enjoy your flavorful Grilled Lime Flat Iron Steak!

Common Mistakes to Avoid

Grilling a perfect flat iron steak can be tricky. Here are some common mistakes to watch out for.

Skipping the marination: Not marinating the steak can lead to a lack of flavor. Always allow time for the marinade to infuse the meat, ideally overnight.
Ignoring the meat temperature: Cooking straight from the refrigerator can result in uneven cooking. Let the steak sit at room temperature for about 30 minutes before grilling.
Not preheating your grill: A cold grill will not sear the meat properly. Make sure your grill is preheated to medium-high heat for that delicious crust.
Overcooking the steak: Cooking too long can dry out your steak. Use a meat thermometer to check doneness; aim for 130°F for medium rare.
Cutting against the grain: Slicing against the grain ensures tenderness. Always pay attention to how the fibers run before cutting.
