Grilling a flat iron steak can be a delicious and satisfying meal. However, getting the cooking time right is essential to ensure that the steak is cooked to perfection. In this article, we will guide you through the process of cooking a flat iron steak on the grill and provide you with some helpful tips along the way.

Choosing the Right Flat Iron Steak

Before we dive into the cooking process, it’s important to choose the right cut of flat iron steak. Look for a steak that has marbling and is about 1 to 1.5 inches thick. This thickness will allow for even cooking and a juicy, flavorful steak.

Preparation and Seasoning

Start by preheating your grill to medium-high heat. While the grill is heating up, take the flat iron steak out of the refrigerator and let it come to room temperature. This step is crucial to ensure even cooking. Season the steak with your favorite steak seasoning or a simple mix of salt, pepper, and garlic powder. Allow the steak to sit with the seasoning for about 30 minutes before grilling.

Cooking Time and Temperature

For medium-rare flat iron steak, grill it for about 4-5 minutes per side. This cooking time is based on a steak that is about 1 inch thick. If your steak is thicker, you may need to adjust the cooking time accordingly. Use a meat thermometer to check the internal temperature. The ideal temperature for medium-rare is around 135°F (57°C).

Grilling Techniques

When grilling flat iron steak, use direct heat grilling. Place the steak directly over the heat source and avoid moving it around too much. This will help to achieve those beautiful grill marks and a delicious charred flavor. It’s also a good idea to oil the grates before placing the steak on the grill to prevent sticking.

Resting and Serving

Once the steak reaches the desired temperature, remove it from the grill and let it rest for about 5 minutes. This resting period allows the juices to redistribute, resulting in a tender and juicy steak. After resting, slice the flat iron steak against the grain and serve it with your favorite sides.

Tips for a Perfectly Grilled Flat Iron Steak

Here are a few additional tips to help you achieve a perfectly grilled flat iron steak:

1. Don’t Overcook:

Avoid overcooking the steak, as it can become tough and dry. Keep a close eye on the cooking time and use a meat thermometer to ensure the steak reaches the desired temperature.

2. Let it Rest:

Allowing the steak to rest after grilling is essential for juicy and tender results. Don’t skip this step!

3. Experiment with Seasonings:

Feel free to get creative with your seasonings. Try different combinations of herbs, spices, and marinades to enhance the flavor of your flat iron steak.

4. Try Reverse Searing:

If you prefer a more evenly cooked steak, consider reverse searing. This technique involves cooking the steak at a low temperature first and then finishing it off with a quick sear on high heat.

5. Use a Meat Thermometer:

A meat thermometer is your best friend when grilling steak. It ensures that you cook the steak to your desired level of doneness.


Grilling a flat iron steak can be a delightful experience when done right.
