Whether you're a novice home cook or a seasoned grill master, there are a few tips you should keep in mind when cooking a flat iron steak to ensure that it turns out perfectly.

In this article, we'll share some key tips for cooking the perfect flat iron steak, from seasoning and cooking temperatures to resting the meat before serving.

Selecting the Right Cut of Flat Iron Steak

Look for marbling. Marbling is the small streaks of fat that run through the meat.

Check for thickness. The ideal thickness for a flat iron steak is around 1 inch. Thicker steaks can be more difficult to cook evenly and may take longer to cook.

Choose a bright red color.

Fresh flat iron steak should be bright red in color with a slight sheen.

Avoid steaks that are dull in color or have a grayish tint, as this may show signs that the meat is past its prime.

Consider the grade. Flat iron steaks are available in USDA Choice or Select grades.

Choice-grade steaks will have more marbling and tenderness than Select grade steaks.

Preparing Your Flat Iron Steak for Cooking

Seasoning Your Flat Iron Steak to Perfection

Understanding the Importance of Temperature

The temperature at which you cook your steak can impact its flavor, texture, and quality.

For best results, it's important to cook at a high temperature for a caramelized outside and juicy inside.

Understanding the Importance of Temperature

Don't forget to use a meat thermometer to check the internal temperature to see if it's safe to consume.

For a medium-rare steak, the internal temperature should reach 130-135°F (54-57°C). And for the medium, it should reach 140-145°F (60-63°C), and for medium-well, it should reach 150-155°F (65-69°C).

Cooking a flat iron steak to the right temperature is crucial to achieving great results.

Overcooking the steak can result in a tough and dry texture and undercooking can result in a raw center.

By watching the temp and using a thermometer, you'll guarantee that your flat iron steak is cooked every time.

Resting Your Flat Iron Steak: How Long and Why?

Resting your flat iron steak is an essential step to achieving a tender and juicy steak.

Resting allows the juices to redistribute in the meat and helps keep it moist.

After cooking your flat iron steak, remove it from the heat source.

Let it rest for at least 5-10 minutes before slicing.

During this time, the inside temperature of the steak will rise slightly as the juices settle in the meat.

This extra cooking allows the steak to come up to its temp, resulting in a tasty cooked steak from edge to center.

Resting Your Flat Iron Steak: How Long and Why?

Resting the steak lets the proteins in the meat relax and reabsorb some of the fluids that were released.

This helps to prevent the juices from running out of the steak when it's sliced.

The amount of time you should rest your flat iron steak depends on its thickness.

As a general rule, thicker steaks need a longer resting time than thinner ones. A good rule of thumb is to let the steak rest for about 1 minute for every 10% of its thickness.

For example, if your steak is 1 inch thick, it should rest for about 6 minutes.

By taking the time to rest your flat iron steak, you'll be rewarded by being the best chef at the next neighborhood cookout.

Make sure to use a knife with a long, thin blade for best results. Slice thinly to get the most flavor out of your flat iron steak, slice it thinly against the grain.
