Ingredients You’ll Need
- 1 lb flat iron steak: This is the star of the dish, known for its tenderness and flavor. Look for a cut that is deep red and well-marbled for the best results.
- 1/4 cup olive oil (plus more for searing): A high-quality extra-virgin olive oil works wonders in the marinade and during cooking to create a beautiful crust.
- 3 tbsp Worcestershire sauce: This brings a complex umami flavor that enhances the beefiness of the steak.
- 2 tbsp red wine vinegar: The acidity brightens the marinade and helps tenderize the meat.
- 4 cloves garlic (minced): Fresh minced garlic adds an aromatic quality that complements the meat beautifully.
- 1/2 tbsp dried thyme: A dash of herbiness that pairs nicely with beef.
- 1 tsp sea salt: Essential for enhancing all the flavors.
- 1/2 tsp black pepper: Freshly ground black pepper adds a subtle heat.
How to Make Flat Iron Steak
- Prepare the Marinade: In a large bowl, whisk together 1/4 cup olive oil, 3 tablespoons Worcestershire sauce, 2 tablespoons red wine vinegar, 4 minced garlic cloves, 1/2 tablespoon dried thyme, 1 teaspoon sea salt, and 1/2 teaspoon black pepper until well combined.
- Marinate the Steak: Add the flat iron steak to the marinade, turning to coat it thoroughly. Cover the bowl and refrigerate for at least 2 hours, or preferably overnight to deeply infuse those flavors.
- Bring to Room Temperature: Remove the steak from the fridge 30-60 minutes before cooking, allowing it to come to room temperature. This ensures even cooking.
- Cook on the Stovetop: Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Once hot, add the flat iron steak and sear for 2-3 minutes per side for rare, 3-4 minutes per side for medium rare, 4-5 minutes per side for medium, 5-6 minutes per side for medium well, or 6-7 minutes for well done. The cooking time will depend on your steak’s thickness, so it’s best to use a meat thermometer.
- Cook on the Grill: Preheat the grill over high heat for at least 10 minutes. Place the flat iron steak on the grill over direct heat, cooking for 3-4 minutes per side for rare, 4-5 minutes for medium rare, 5-6 minutes for medium, 6-7 minutes for medium well, or 7-8 minutes for well done. Again, a meat thermometer is your best friend here.
- Rest the Steak: After cooking, transfer it to a cutting board to rest for 5-10 minutes. This helps retain the juices when you slice.
- Slice Against the Grain: After resting, slice the steak against the grain to ensure each piece is tender and juicy.
Storing & Reheating
Store any leftover flat iron steak in an airtight container in the refrigerator for up to 3 days. If you need to keep it longer, freezing is an option for up to 3 months. When you’re ready to enjoy, reheat it in a skillet over low heat or in the microwave for a quick warm-up. Just be aware that the texture may change slightly upon reheating, but a drizzle of olive oil can refresh its juiciness.
Chef’s Helpful Tips
- Avoid overcooking! Keep a close eye on the time and use a meat thermometer to ensure perfect doneness.
- Letting the steak come to room temperature before cooking is crucial for even cooking.
- If you marinate the steak overnight, it will be even more flavorful, but don’t go past 24 hours to avoid a mushy texture.
- Use high heat for a great sear, but medium heat works perfectly to finish cooking.
- Play around with the marinade! Add herbs like rosemary or spices like smoked paprika for a new twist.
Although flat iron steak stands out for its exceptional flavor and tenderness, it’s also an inviting canvas for creativity. I encourage you to experiment with different marinades or serve it alongside your favorite sides. This dish isn’t just a meal — it’s a great excuse to gather loved ones around the table and share a delicious moment.
Recipe FAQs
How do I know when my flat iron steak is cooked?
The best way to check the doneness is by using a meat thermometer. Aim for 120°F (49°C) for rare, 130°F (54°C) for medium rare, and 140°F (60°C) for medium. Remember, the temperature will continue to rise a bit after cooking, so take it off the heat just shy of your desired temperature.
Can I marinate the steak for longer than 24 hours?
While it’s ideal to marinate for at least 2 hours, no longer than 24 hours is recommended. Beyond that, the marinade can break down the meat too much, resulting in an undesirable texture.
What is the best way to slice flat iron steak?
Always slice against the grain, which refers to cutting across the fibers of the meat. This technique shortens those fibers, making each bite tender and easier to chew.
Can I substitute for flat iron steak?
Yes! If you can’t find flat iron steak, other steak cuts such as flank or skirt steak work in a pinch. Just keep in mind that cooking times may vary based on the thickness and marbling of the cut.
