Directions: flat iron steak recipes

1. Whisk Together: In a bowl, whisk together ¼ cup of low sodium soy sauce, 2 tablespoons of olive oil, 2 tablespoons of balsamic vinegar, 2 minced cloves of garlic, 1 teaspoon of freshly ground black pepper, and 1 teaspoon of dried rosemary until well combined.
2. Marinate the Steak: Place your trimmed and patted dry 2 pounds flat iron steak in a resealable plastic bag. Pour the marinade over the steak, seal the bag tightly, and refrigerate for at least 1 hour or up to 8 hours to enhance flavor.
3. Preheat the Grill: Preheat your grill to high heat, ensuring it's nice and hot to achieve that perfect sear on your steak—aim for temperatures around 450°F.
4. Prepare the Steak: Once marinated, remove the flat iron steak from the bag and discard the marinade. Let it sit at room temperature for about 15 minutes; this step helps in cooking evenly.
5. Grill the Steak: Place the steak on the hot grill and cook for about 4-5 minutes on each side for a delightful medium-rare finish or until your desired doneness is reached.
6. Check Temperature: Use a meat thermometer to check the internal temperature of your steak; it should read approximately 130°F for that juicy medium-rare perfection.
7. Rest Before Slicing: Carefully remove the steak from the grill and let it rest for about 5 minutes. This resting period allows juices to redistribute for maximum tenderness.
8. Slice and Serve: Slice your beautiful grilled flat iron steak against the grain into tender pieces and serve with your favorite sides—think roasted veggies or a fresh salad!
Optional: Garnish with fresh herbs for added flavor and color.

flat iron steak recipes Recipe FAQs
What is the best way to select a flat iron steak?
When choosing a flat iron steak, look for one that is bright red in color with good marbling. The marbling, or intramuscular fat, will help keep the beef juicy and flavorful during grilling. Aim for a piece weighing around 2 pounds, trimmed and patted dry for optimal results.
How long should I marinate my flat iron steak?
For the best flavor infusion, marinate your flat iron steak for at least 1 hour and up to 8 hours. This allows the soy sauce and balsamic vinegar to tenderize the meat while enhancing its savory profile. Just remember to refrigerate it during this time!
Can I freeze leftover grilled flat iron steak?
Absolutely! If you have leftovers, let the grilled steak cool completely before wrapping it tightly in plastic wrap or aluminum foil. You can also place it in an airtight freezer bag. It will stay fresh for up to 3 months in the freezer. When you’re ready to enjoy it again, simply thaw it overnight in the refrigerator.
What sides pair well with grilled flat iron steak?
Grilled flat iron steak is incredibly versatile! Consider serving it with classic sides like garlic mashed potatoes, grilled vegetables, or a fresh arugula salad dressed with lemon vinaigrette. These complement the rich flavors of the steak beautifully.
How can I tell when my flat iron steak is cooked perfectly?
Using a meat thermometer is key! For medium-rare doneness, aim for an internal temperature of 130°F. Cook for about 4-5 minutes on each side over high heat until you achieve that perfect sear and juicy tenderness.
What if my steak is tough after cooking?
If your flat iron steak turns out tough, it's likely due to overcooking or slicing against the grain. Always allow it to rest for about 5 minutes after grilling before slicing. Make sure to cut against the grain for tender bites—this breaks up muscle fibers and enhances chewability!
