Flat Iron Steak Recipe
This flat iron steak recipe is as simple and delicious as a steak can be. This juicy and tender cut is marinated to slightly tenderize the meat, then grilled for a delicious flavor. With just 15 minutes of active cooking time, this impressive main course will be ready to compliment any side dish.
Ingredients
- 1 ½ lbs flat iron steaks
- 2 tablespoons olive oil
- 2 tablespoons red wine vinegar
- 4 garlic cloves pressed
- 2 tablespoons chopped fresh rosemary
- ½ teaspoon ground black pepper
- 1 teaspoon coarse kosher salt
Instructions
- In a large freezer bag, mix olive oil, red wine vinegar, garlic, rosemary, salt, and pepper.
- Place the flat iron steaks into the bag, squeeze out the air, and close the bag.
- Gently massage the marinade into the meat, ensuring the steaks are evenly coated with the marinade. Marinate in the refrigerator for at least 1 hour, or overnight.
- When ready to grill, preheat the grill to 450°F. Clean and grease the grates with an oil-soaked paper towel.
- Place the steaks on the direct heat. Grill for 5 minutes, then flip and sear for another 5 minutes or so. For medium rare, cook until the internal temperature reaches 130°F. Off heat, the meat will continue to cook, and the internal temperature will reach about 135°F while resting.
- Cover the steaks with foil and rest for at least 5 minutes before slicing and serving.
Notes
Note 1: Marinate the steak for 1 hour up to overnight. The longer you marinate the more flavor the steak will have. You don't want to marinate for too long though or the vinegar and salt can start to break down the meat too much changing the texture.
Note 2: Grease your grill well before preheating. We recommend rubbing the grill grates with an oiled paper towel and then turning the grill on.
Note 3: You can also cook the steaks indoors on the stove. If that's preferred, use a grill pan or cast iron skillet for a nice sear.
Note 4: Let the steaks rest for at least 5 minutes before slicing and serving. This is required and one of the most important tips when cooking steak. When you allow the steak to rest this let's the juices settle making for a more juicy bite after slicing.
Note 5: Use a meat thermometer to know when the steak is done cooking. You want to cook to 145ºF for medium-rare. This is the best way to avoid overcooking the steak and making sure it's restaurant-quality right at home.
Storing Tips:
- Store any leftover steak in an airtight container in the fridge for up to 4 days. This steak is great served cold or room temperature as leftovers. But if you do want to reheat it, be cautious when microwaving because you can very easily overcook it. We have a great recipe for leftover steak salad and steak fried rice that are nice alternatives too.
- We don't recommend freezing cooked steak as it can often change the texture once thawed and reheated. If you want to freeze the steak uncooked, that's a great option. Just wrap in plastic wrap and place in the freezer for up to 2 months. Thaw in the fridge overnight before cooking.
- When it comes to prepping the steak in advance, we love to marinate it the day before a party for easy cooking when guests arrive. It also makes for a quick weeknight dinner.
