What Is Flat Iron Steak?
Flat iron steak is a beef cut from the shoulder area, specifically from the top blade. It is known for being tender, well-marbled, and full of rich beef flavor. Even though it comes from the chuck area, flat iron steak is not a slow-cooking roast. It is best treated like a steak and cooked hot and fast.

Best Ways to Cook Flat Iron Steak
The best way to cook flat iron steak is with high heat and a short cooking time. This helps create a flavorful crust on the outside while keeping the inside juicy. Flat iron steak does not need a long cooking time, and it is usually best served medium-rare or medium.
Flat iron steak works well with a simple seasoning of salt and pepper, but it also takes beautifully to marinades, garlic butter, chimichurri, citrus, herbs, and smoky spices. For the best texture, let the steak rest after cooking and slice it thin against the grain.
The three best cooking methods for flat iron steak are:
- Grilling for smoky flavor and a beautiful crust.
- Cast iron searing for a rich, steakhouse-style finish.
- Slicing for tacos, bowls, salads, sandwiches, and fajitas.
Below are three flavorful flat iron steak recipes that use those methods.
1. Grilled Flat Iron Steak with Garlic-Herb Marinade
This grilled flat iron steak recipe uses a simple flat iron steak marinade made with olive oil, Worcestershire sauce, balsamic vinegar, garlic, Dijon mustard, and fresh herbs. The marinade adds savory flavor while still letting the beef shine.
Ingredients
- 2 Homestead flat iron steaks, about 8 to 12 oz each
- 3 Tbsp olive oil
- 2 Tbsp balsamic vinegar
- 1 Tbsp Worcestershire sauce
- 3 cloves garlic, minced
- 1 tsp Dijon mustard
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1 tsp chopped fresh rosemary, or 1/2 tsp dried rosemary
- 1 tsp chopped fresh thyme, or 1/2 tsp dried thyme
- Flaky salt, optional for serving
Instructions
- Pat the flat iron steaks dry with paper towels.
- In a bowl, whisk together olive oil, balsamic vinegar, Worcestershire sauce, garlic, Dijon mustard, salt, pepper, rosemary, and thyme.

Cooking Tip: Flat iron steak does not need to marinate overnight. One to two hours is enough to add flavor while keeping the beef texture just right.
2. Cast Iron Flat Iron Steak with Garlic Butter
This cast iron flat iron steak is simple, quick, and full of steakhouse-style flavor. A hot skillet gives the steak a deep brown crust, while garlic butter adds richness at the end. This is one of the best ways to cook flat iron steak when you want a flavorful dinner without firing up the grill.
Ingredients
- 2 Homestead flat iron steaks, about 8 to 12 oz each

- Add oil to the skillet. Place steaks in the pan and sear for 3 to 4 minutes without moving them.
- Flip the steaks and cook for another 2 to 4 minutes, depending on thickness.
- Reduce heat to medium-low. Add butter, garlic, rosemary, and thyme to the skillet.
- Tilt the skillet slightly and spoon the melted garlic butter over the steaks for 30 to 60 seconds.
- Remove steaks from the skillet and rest for 5 to 10 minutes.
- Slice thin against the grain and spoon a little extra garlic butter over the top before serving.
Cooking Tip: A dry steak and a hot pan are the keys to a great crust. Pat the steak dry before seasoning and let the skillet fully heat before adding the meat.

Cooking Tip: Chimichurri is best when it has a few minutes to sit before serving. Make it before cooking the steak so the flavors can come together.
Flat Iron Steak Temperature Guide
Flat iron steak is best when cooked to medium-rare or medium. Because it is naturally tender and flavorful, cooking it too far past medium can make it less juicy. A meat thermometer is the easiest way to get the flat iron steak temperature right.
- Rare: 125 degrees F
- Medium-rare: 130 to 135 degrees F
- Medium: 140 to 145 degrees F
- Medium-well: 150 to 155 degrees F
Remove the steak from the heat a few degrees before your final target temperature. The temperature will continue to rise slightly while the steak rests.
How to Make Flat Iron Steak Tender
Flat iron steak is already a tender cut, but the right cooking and slicing methods make a big difference. Use high heat, avoid overcooking, and give the steak time to rest before slicing.
For a tender flat iron steak, remember these simple tips:
- Pat the steak dry before cooking so it can sear properly.
- Use a hot grill or hot cast iron skillet.
- Cook to medium-rare or medium for the best texture.
- Let the steak rest for 5 to 10 minutes before slicing.
- Slice thin against the grain.
If you are wondering how to slice flat iron steak, look for the direction the muscle fibers run and cut across them instead of with them. This makes each bite more tender and easier to chew.
What to Serve with Flat Iron Steak
Flat iron steak is versatile enough for steak dinners, tacos, salads, bowls, and quick family meals. Depending on which recipe you choose, try serving it with:
