How to Cook Flat Iron Steak on the Grill

Grilling a Flat Iron steak with a simple marinade and selecting the perfect side or drink to go with your dinner will make for an excellent meal. Choose a favorite Flat Iron steak recipe for the grill and select one of two main approaches:

• Charcoal Grilling
• Gas Grilling

Regardless of which method you choose, be sure your steaks are completely thawed before cooking. We recommend thawing in the refrigerator for at least 24 hours. Once thawed, remove your steak from the refrigerator approximately 30–40 minutes before cooking to allow the steak to come to room temperature. Lastly, season your steak as desired. Grill your Flat Iron steak and season your meat to taste with Kansas City Steak Original Steak Seasoning, which will enhance the flavor.

Grilling Flat Iron Steak: Charcoal vs. Gas Grill

How to Cook Flat Iron Steak on a Charcoal Grill

Preheat your grill on high. Place steaks over the hottest part of the grill, and sear both sides for 1–2 minutes. Then move to medium, ash-covered coals and continue to grill for the times listed in the Cooking Times Chart below. Turn about 1 minute prior to the halfway point.

How to Cook Flat Iron Steak on a Gas Grill

Preheat your grill on high. Sear both sides for 1–2 minutes, then reduce to medium heat and continue to grill for the times listed in the Cooking Times Chart below. Turn about 1 minute prior to the halfway point.

Grilling Flat Iron Steak Medium-Rare (recommended)

• Grill for 12–14 minutes for a 1–1½ inch steak, turning about 1 minute before the halfway point. A meat thermometer should read 130°F.
• Rest your steaks for 5 minutes before serving, covering lightly with foil. The temperature of the meat will continue to rise about 5°F during this time (this is called "carryover cooking"). The final temperature will read 135°F.
• Resting steak is important because the heat of cooking pulls the juices in the meat toward the surface; if you slice into it immediately after cooking, those flavorful juices will end up on your plate, not in your steak. Allowing your steak to rest will give the juices time to sink back in and throughout the meat, keeping it moist and flavorful.
• To check the degree of doneness, use a meat thermometer to measure the internal temperature of your steak.
• Prior to serving, add a Kansas City Steak Finishing Butter for an additional flavor boost.
