What is flat iron steak?
Flat iron steak, also known as top blade steak, butlers’ steak, and oyster blade steak, is a well-marbled, tender cut of beef that comes from the shoulder area of the cow. The name “flat iron” refers to its shape, which resembles an old-fashioned flat clothing iron.
Despite being a more affordable alternative to premium cuts, like ribeye and filet mignon, flat iron offers a similar taste and texture whether you sear it in a cast iron skillet, reverse-sear, or cook it on the grill.
- Flat iron steak. Look for steaks that are marbled with fat and have a consistent thickness. If you can find Wagyu flat iron, even better!
- Olive oil. This is the base of the marinade. It acts as a natural tenderizer for the meat and prevents it from sticking to the grill grates.
- Garlic cloves. Freshly minced to intensify the overall savory flavor profile of the beef.
- Smoked paprika. Adds a rich, distinctively smoky flavor.
- Salt and black pepper. To taste.
How to cook flat iron steak on the grill
- Make the marinade. Stir the olive oil, minced garlic, smoked paprika, pepper, and salt together in a small bowl.
- Marinate the steak. Place the steak in a shallow bowl or ziplock bag. Pour the marinade over top and massage it into the meat until fully coated. Set aside to marinate.
- Grill. Transfer the steak from the bowl with the marinade and onto a hot grill. Cook to medium-rare or your desired temperature.
- Rest, slice, and serve. Transfer the steak to a cutting board to rest for a few minutes. Afterward, slice it against the grain and serve.
Flat iron steak temperature guide
Use a meat thermometer and this guide to make sure your steak is cooked exactly how you like it. Flat iron steak is best when it’s cooked to medium-rare or medium:
- Rare – 125ºF
- Medium-rare – 135ºF
- Medium – 145ºF
- Medium-well – 155ºF
- Well-done – 165ºF
Keep in mind that the steak will continue to come up to temperature as it rests, so it’s best to remove it from the grill when it’s 5 degrees away from your desired doneness.
What to serve with this dish
Like hanger steak and arrachera, the flat iron is a fantastic steak to cut into strips for tacos and fajitas or to serve on top of a salad. It’s also great as a standalone protein drizzled with chimichurri sauce or a red wine reduction.
To complete the meal, pair it with any of these tasty sides:
- Air Fryer Asparagus
- Baked Sweet Potatoes
- Sauteed Mushrooms
- Air Fryer Broccoli
- Sauteed Spinach
- Keto Coleslaw
To store: Keep the leftovers in an airtight container in the refrigerator for 3 to 4 days.
To reheat: Reheat the steak in a baking dish with a splash of beef broth in a 250ºF oven until the internal temperature reaches 110ºF.
Recommended tools to make this recipe
- Shallow bowl or large ziplock bag. To marinate the beef.
- Grill or grill pan. To sear the steak.
- Tongs. To flip the steaks on the grill.
- Meat thermometer. To ensure the steaks are cooked to your desired temperature.
- Chef’s knife. To slice the cooked steak after resting.
Recipe tips and tricks
- You can marinate flat iron steak for a minimum of 30 minutes or up to 8 hours. Place the meat and marinade in the fridge if you’re letting it marinate for longer than 30 minutes.
- Bring to room temperature. Place the steak on the counter for 20 to 30 minutes before grilling so it cooks more evenly.
- Always preheat the grill. Make sure the grill reaches between 450°F and 500°F so the steak sizzles as soon it hits the grill grates. If you use a grill pan and cook this stovetop, I like to use the largest burner so the pan is well heated at all times.
- Let the steak rest for at least 5 minutes after grilling. This way, the natural juices can redistribute, making the meat extra juicy and flavorful.
- Slice against the grain. Slicing the steak against the grain is critical to shortening the meat fibers and giving you more tender slices. It’s also great if you are using it in other dishes like a steak salad.
