Steak is a versatile and delicious protein that can be cooked in various ways, depending on your preferences. Among the different types of steak, flat iron steak has gained popularity in recent years due to its tenderness and flavor. This article will guide you through cooking flat iron steak to perfection.
Before we dive into the cooking process, let’s first understand what flat iron steak is and how to choose the right cut.
Choosing the Right Cut
When choosing a flat iron steak, look for one that has consistent marbling and is about 1-2 inches thick. The marbling in the steak will provide flavor and tenderness, while the thickness will ensure that the steak cooks evenly.
Now that we have the right cut of meat let’s move on to the cooking process.
Ingredients:
- Flat iron steak
- Salt
- Black pepper
- Olive oil or vegetable oil
- Butter (optional)
- Garlic cloves (optional)
- Rosemary sprigs (optional)
Tools:
- Cast iron skillet or heavy-bottomed skillet
- Tongs
- Meat thermometer
Steps to Cook Flat Iron Steak

Step 1: Preparation
Remove the flat iron steak from the refrigerator and let it sit at room temperature for about 30 minutes. This helps the steak cook more evenly. Pat the steak dry with paper towels and season both sides with salt and black pepper.
Step 2: Preheat the skillet
Put the skillet on the stovetop and heat it over medium-high heat. Once the skillet is hot, swirl a tablespoon of olive or vegetable oil around it to coat the bottom.
Step 3: Sear the steak
Place the seasoned flat iron steak into the skillet and cook for 3-4 minutes on each side until a crust forms. Use tongs to flip the steak, and don’t move the steak around too much to ensure that a crust forms.
Step 4: Add butter, garlic, and rosemary (optional)
If desired, add a few garlic cloves, rosemary sprigs, and a tablespoon of butter to the skillet during the last minute of cooking. Use a spoon to baste the steak with the melted butter and aromatics.
Step 5: Check the temperature
Utilize a meat thermometer to verify the internal temperature of the steak. For medium-rare, the temperature should be around 130°F (54°C). For medium, the temperature should be around 135°F (57°C).
Step 6: Rest the steak
Remove the steak from the skillet and let it rest on a cutting board for 5-10 minutes. This allows the juices to redistribute and makes for a more tender steak.
Step 7: Slice and serve
After resting, slice the steak against the grain and serve immediately. Enjoy!

How do I know my flat iron steak is done?
There are several ways to tell if your flat iron steak is done:
- Use a meat thermometer: This is the most accurate way to determine the steak’s internal temperature. For medium-rare, the steak should reach 130°F (54°C), and for medium, it should reach 135°F (57°C).
- Touch test: Use your fingers to test the steak’s doneness by comparing it to the firmness of different parts of your hand. A rare steak will feel like the base of your thumb when you touch your thumb to your index finger, while a medium steak will feel like the base of your thumb while touching your thumb to your middle finger.
- Visual cues: Look at the color and texture of the meat. For medium-rare, the inside of the steak should be pink with a warm red center, while a medium steak will have a slightly pink center with a more browned exterior.
Let the steak rest for a few minutes before slicing and serving to allow the juices to redistribute and ensure the meat is tender and flavorful.
Why is my flat iron steak chewy?
There are a few reasons why your flat iron steak may be chewy:
- Overcooking: Flat iron steak is a relatively thin cut of meat, so it cooks quickly. Overcooking it can result in a tough, chewy texture.
- Not resting the steak: Let the steak rest for a few minutes before slicing and serving to allow the juices to redistribute. If you cut into the steak too soon, the juices will escape, and the meat will be tougher
- Not slicing against the grain: Slicing the steak against the grain helps to break up the muscle fibers and make the meat tenderer. Ensure that you slice the meat perpendicular to its grain.
- Poor quality meat: Flat iron steak is generally a tender cut, but if the meat is tough, it will be chewy no matter how cooked.
To avoid a chewy flat iron steak, cook it properly and let it rest before slicing. Choose high-quality meat and slice against the grain for the best texture.
Can flat iron steak be tender?
