Flat Iron Steak Recipe: Juicy Asian-Style Marinade

This flat iron steak recipe uses a soy, honey, and garlic marinade to give you a tender steak with a savory, lightly sweet crust. You marinate the steak for 4 hours, then grill it for about 10 minutes. The short cook time keeps the center pink and juicy, and thin slices keep every bite tender. The same method also works in a skillet, oven, or air fryer, so you can cook it with whatever you have.

Quick Answer

• What it is: Grilled flat iron steak in an Asian-style soy, honey, and garlic marinade
• Total time: 4 hours 35 minutes (15 min prep, 4 hours marinating, 10 min cooking, 10 min resting)
• Difficulty: Easy
• Servings: 4
• Key tip: Pull the steak at 130°F for medium-rare, then slice it thin against the grain.

Ingredients

For the steak and marinade

• 1½ to 2 pounds flat iron steak (1 to 1¼ inches thick)
• ¼ cup low-sodium soy sauce
• 2 tablespoons red wine vinegar
• 2 tablespoons olive oil
• 1 tablespoon honey
• 3 garlic cloves, minced
• 1 tablespoon ginger paste (or 1 tablespoon freshly grated ginger)
• 1 teaspoon coarsely ground black pepper
• 3 whole scallions, trimmed

For serving

• 4 cups cooked white rice
• 2 sliced scallions
• 1 tablespoon sesame seeds

What each ingredient does: Soy sauce adds salt and savory depth. The vinegar softens the surface of the meat and balances the honey. Honey helps the crust brown. Olive oil carries the garlic and ginger flavor into the steak.

Swaps: Use dry sherry instead of red wine vinegar. Use tamari for a gluten-free version. Maple syrup works in place of honey.

Equipment

• Grill (gas or charcoal)
• Zip-top bag or shallow dish with a lid
• Tongs
• Instant-read thermometer
• Cutting board and sharp knife

How to Choose and Trim Flat Iron Steak

Look for steaks about 1 to 1¼ inches thick with fine, even marbling. Flat iron comes from the chuck, or shoulder, and is also sold as top blade steak. Butchers cut out the tough line of connective tissue that runs through the middle of the whole muscle, so most store-bought steaks are already trimmed.

At home, remove any hard fat and any silvery membrane you can see. Leave thin streaks of soft fat, since they add flavor. Pick steaks of similar thickness so they finish at the same time.

Asian-Style Grilled Flat Iron Steak, Step by Step

1. Whisk the marinade. Combine the soy sauce, vinegar, olive oil, honey, garlic, ginger, and pepper in a bowl. Stir until the honey dissolves.
2. Trim the steak. Cut away hard fat and silvery membrane.
3. Marinate in the fridge. Put the steak, marinade, and whole scallions in a zip-top bag. Press out the air and refrigerate for 4 hours, up to 6. A bag keeps the marinade in contact with all sides of the meat. Turn the bag once halfway through.
4. Take the steak out 20 minutes before cooking. A less-chilled steak cooks more evenly.
5. Heat the grill to medium-high, 450 to 500°F. Clean the grates and brush them with oil.
6. Remove the steak and wipe off the solids. Scrape off garlic and scallion bits, which burn quickly. Discard the used marinade. Raw meat touched it.
7. Grill the first side for 45 seconds. Rotate the steak a quarter turn for crosshatch marks, then grill another 45 seconds.
8. Flip and repeat. Grill the second side the same way. Keep flipping every 90 seconds until the steak reaches 130°F in the thickest part, about 8 to 10 minutes total for a 1-inch steak. Start checking at 7 minutes.
9. Rest the steak for 5 to 10 minutes. Leave it on a cutting board so the juices settle back into the meat.
10. Slice thin against the grain. Cut ¼-inch slices across the visible muscle lines.
11. Serve over white rice. Top with sliced scallions and sesame seeds.

Tips for Best Results

• Marinate 4 to 6 hours. Soy and vinegar start to break down the outer layer of the meat. Past 6 hours, the surface turns mushy and salty.
• Use an instant-read thermometer. Flat iron is thin, and it moves from medium-rare to dry in a couple of minutes.
• Wipe off the solids. Garlic and scallion bits char fast and taste bitter.
• Watch the honey. Honey browns quickly. If the outside darkens before the center is ready, slide the steak to a cooler part of the grill.
• Slice thin. Thick slices of a lean-textured steak feel chewy.

Common Mistakes and How to Fix Them

Flat Iron Steak Recipe Grill

For the recipe above, use direct medium-high heat on a gas or charcoal grill. For charcoal, bank the coals to one side to make a hot zone and a cooler zone. Start the steak over the hot side and move it to the cool side if flare-ups or burning start.

Cook times by thickness over 450 to 500°F:

• ¾ inch: about 3 to 4 minutes per side
• 1 inch: about 4 to 5 minutes per side
• 1¼ inches: about 5 to 6 minutes per side

These are estimates, so check temperature rather than time. Keep the lid closed between flips on a gas grill to hold the heat.

Flat Iron Steak Recipe Cast Iron

A cast iron skillet gives flat iron steak a deep, even crust. Heat the pan over medium-high for 5 minutes. Add 1 tablespoon of avocado oil or another high-heat oil. Sear the steak for 3 to 4 minutes per side, and pull it at 130°F.

1. Pat the marinated steak very dry with paper towels. This helps the crust form instead of steaming the meat.
2. Preheat the skillet until the oil shimmers.
3. Lay the steak away from you to avoid splatter.
4. Sear 3 to 4 minutes, flip, and sear another 3 to 4 minutes.
5. For extra richness, add 1 tablespoon of butter in the last minute and spoon it over the steak.
6. Rest and slice as above.

Because of the honey, use medium-high instead of high heat to keep the crust from scorching. Turn on your exhaust fan.

Flat Iron Steak Recipe Stove Top

You can cook flat iron steak on the stove top in any heavy skillet or grill pan. Use medium-high heat, 1 tablespoon of oil, and 3 to 4 minutes per side for a 1-inch steak. Follow the cast iron method above, since the heat and timing are the same.

A stainless steel pan or grill pan works well. Avoid thin non-stick pans, which do not hold heat and can release fumes at high temperatures. Wipe the pan between batches if you cook more than two steaks. Let the pan reheat before adding the next steak.

Flat Iron Steak Recipe Oven

The oven finishes flat iron steak gently, which works well for thicker cuts. Sear it in an oven-safe skillet for 2 minutes per side, then move the skillet to a 400°F oven for 3 to 6 minutes. Pull the steak at 130°F.

For a reverse sear, which gives very even doneness:

1. Place the dried steak on a wire rack over a baking sheet.
2. Bake at 275°F until the center reaches 110 to 115°F, about 20 to 30 minutes.
3. Sear in a hot skillet for 60 to 90 seconds per side.
4. Rest 5 minutes and slice.

Oven times vary with steak thickness and oven accuracy, so rely on the thermometer.

Flat Iron Steak Recipe Air Fryer

Preheat the air fryer to 400°F, then cook a 1-inch flat iron steak for 8 to 10 minutes, flipping once halfway. Check the temperature at 7 minutes and pull it at 130°F. These times are a starting point, since air fryer models cook differently.

• Cut large steaks in half so they fit in one layer.
• Pat the steak dry before cooking.
• Do not crowd the basket, since air needs to circulate.

An air fryer gives a decent crust, though not the deep char of a grill or cast iron pan.

Flat Iron Steak Recipe No Marinade

For a flat iron steak recipe with no marinade, season with salt and pepper and cook it hot. Use 1 teaspoon of kosher salt (Diamond Crystal) per pound of meat. Use a little less if you have Morton, which is saltier by volume. Add ½ teaspoon of black pepper per pound. Cook using any method above.

For better flavor, dry brine: salt the steak, set it on a rack uncovered in the fridge, and leave it for 45 minutes to 24 hours. The salt seasons the meat deeply and dries the surface, which helps browning. Finish with a spoonful of butter or a squeeze of lemon.

Flat Iron Steak Recipe Bobby Flay

Bobby Flay’s flat iron steak recipes follow the same core approach as this one: high heat, bold seasoning, a pink center, and thin slices. For the exact ingredients and timing he uses, check his original recipe, since versions vary.

To borrow the idea, swap the marinade here for a spice rub or a herb sauce, and keep the grilling and slicing steps the same.

Doneness Temperature Chart

Pull the steak at the “pull” temperature. It will rise about 5°F as it rests.

Flat iron is best between medium-rare and medium, and it dries out past that. The USDA recommends 145°F with a 3-minute rest for whole cuts of beef. Cook to that number if you want to follow the guideline exactly.

What to Serve with Flat Iron Steak

White rice is the classic pairing and soaks up the sliced steak’s juices. Other good sides:

• Steamed broccoli with sesame oil
• Sautéed bok choy with garlic
• Cucumber salad with rice vinegar
• Garlic green beans
• Sesame noodles

Storage, Make-Ahead, and Reheating

• Fridge: Store cooked steak in an airtight container for 3 to 4 days.
• Freezer: Freeze sliced steak flat in a freezer bag for up to 3 months. Thaw overnight in the fridge.
• Make-ahead: Mix the marinade up to 2 days ahead and keep it covered in the fridge. Add the raw steak only when you are ready to marinate.
• Reheat: Warm slices in a skillet over medium-low heat for 1 to 2 minutes with a splash of water or broth. Microwave at 50% power in short bursts to avoid toughness. You can also eat the slices cold.

FAQs

What is the best way to cook a flat iron steak?

Cook it hot and fast, using a grill or cast iron skillet, to a medium-rare or medium finish. Then slice it thin across the grain. See the method sections above for exact times.

Is flat iron steak tender or tough?

It is one of the more tender cuts from the chuck, with good marbling and beefy flavor. It turns tough if you overcook it or slice with the grain. Cook it to medium-rare and cut it across the muscle lines.

What can I make out of flat iron steak?

Slice it for rice bowls, tacos, fajitas, or steak salads. You can also pile it on sandwiches, toss it into stir-fry noodles, or serve it whole with a sauce. Leftover slices work well in fried rice.

What is flat iron steak best for?

It is best for quick, high-heat cooking such as grilling, searing, and broiling. Its even thickness gives consistent results, and it takes marinades well. It is less suited to long, dry cooking, which makes it chewy.

How do I know flat iron steak is done without a thermometer?

Press the center with your finger. Medium-rare feels like the fleshy base of your thumb when you touch your thumb to your middle finger. This method is less accurate than a thermometer, especially for thin steaks.

Can I use this marinade on other cuts?

Yes. It works on skirt steak, flank steak, and sirloin. Thin cuts need 2 to 4 hours, and thicker cuts can go up to 6. Cooking times change with the cut, so use a thermometer.
