Flat iron steak is quickly becoming a favorite among steak lovers for its rich flavor, tenderness, and affordable price. If you’re wondering how to cook flat iron steak on the stove to get that perfect sear and juicy interior, you’re in the right place! This guide will walk you through the steps to pan-sear your flat iron steak like a pro, with tips to maximize flavor and tenderness.
What Makes Flat Iron Steak Special?
Flat iron steak comes from the shoulder of the cow and is known for its marbling and beefy flavor. It’s a relatively tender cut that cooks quickly and benefits from high-heat searing to develop a beautiful crust while keeping the inside juicy and medium-rare. Cooking it on the stove with a cast iron or heavy skillet is one of the best ways to get a steakhouse-quality result at home.
Ingredients You’ll Need
– 1 flat iron steak (about 1 inch thick)
– 1 tablespoon vegetable oil or oil with a high smoke point (avocado or refined olive oil works well)
– Kosher salt
– Freshly ground black pepper
– Optional: garlic powder, onion powder for extra flavor
– Butter (about 2 tablespoons)
– Fresh herbs like rosemary or thyme (optional)
– 2-3 cloves garlic, lightly crushed (optional)
Step-by-Step Instructions to Cook Flat Iron Steak on the Stove
1. Prepare Your Steak and Pan
– Take the flat iron steak out of the fridge about 30 minutes before cooking to bring it to room temperature. This helps it cook more evenly.
– Pat the steak dry with paper towels. Moisture on the surface will prevent a good sear.
– Season both sides generously with kosher salt, black pepper, and any other seasonings you like.
– Heat a cast iron skillet or heavy-bottomed pan over medium-high to high heat until it’s very hot and just starting to smoke. This is key for a great crust.
2. Sear the Steak
– Add the oil to the hot pan and swirl to coat.
– Carefully place the steak in the pan. It should sizzle loudly.
– Let it cook undisturbed for about 3-4 minutes. Don’t move or flip it too soon; the steak will release easily from the pan when it’s ready to flip.
– Flip the steak using tongs and sear the other side for another 3-4 minutes.
3. Add Butter and Aromatics (Optional but Recommended)
– Reduce the heat to medium-low.
– Add butter, crushed garlic cloves, and fresh herbs like rosemary or thyme to the pan.
– Tilt the pan slightly and use a spoon to baste the steak with the melted butter and aromatics. This adds richness and flavor.
4. Check for Doneness
– Use an instant-read meat thermometer to check the internal temperature.
– For medium-rare, aim for about 125°F (52°C) before resting. The steak will continue to cook slightly after removing from heat.
– If the steak needs more time, lower the heat and cook for another 1-2 minutes per side, basting as you go.
5. Rest Your Steak
– Transfer the steak to a cutting board and loosely tent with foil.
– Let it rest for 5-10 minutes. This step allows the juices to redistribute, making your steak juicy and tender.
6. Slice and Serve
– Slice the steak thinly against the grain. Cutting against the grain shortens muscle fibers, making the steak easier to chew and more tender.
– Serve immediately. You can top it with the pan juices or crispy shallots for extra flavor.
Tips for Perfect Flat Iron Steak on the Stove
– Don’t rush the sear: Let the steak develop a crust before flipping.
– Use a heavy pan: Cast iron is ideal for even heat and great searing.
– Season well: Salt and pepper are your best friends.
– Use a thermometer: Avoid guessing doneness to prevent overcooking.
– Rest your steak: It’s crucial for juicy results.
– Slice against the grain: This makes every bite tender.
Variations and Flavor Boosters
– Add smoked paprika or chili powder to your seasoning for a smoky kick.
– Use compound butter (butter mixed with herbs and garlic) for basting.
– Serve with a green sauce or chimichurri for a fresh, zesty finish.
– Try caramelized shallots or roasted garlic as toppings for an elegant touch.
Cooking flat iron steak on the stove is straightforward and rewarding. With a hot pan, simple seasoning, and a little patience, you can enjoy a steak that’s tender, juicy, and packed with flavor right from your kitchen.
