Ingredients You Will Need

🩷 Flat Iron Steak: 1 lb, known for its tenderness and rich flavor.
🩷 Olive Oil: 2 tbsp, to sear the steak and lock in moisture.
🩷 Garlic: 2 cloves, minced, for a deep, aromatic flavor.
🩷 Salt: 1 tsp, to enhance the steak’s natural taste.
🩷 Black Pepper: 1 tsp, for a subtle, spicy kick.
🩷 Fresh Herbs: Optional (rosemary or thyme), for an added depth of flavor.

Step-by-Step Instructions

🔵 Step 1: Prep the Steak
Remove the steak from the refrigerator and let it sit at room temperature for about 30 minutes. This ensures even cooking and prevents the steak from seizing up when it hits the heat.

🔵 Step 2: Season the Steak
Rub the steak with olive oil, minced garlic, salt, and pepper. If you’re using fresh herbs, finely chop them and press them gently into the steak to infuse flavor.

🔵 Step 3: Cook the Steak
Grilling Method: Preheat your grill to high heat. Place the steak on the grill and cook for 4–5 minutes per side for medium-rare. Adjust the time for your preferred level of doneness.
Pan-Searing Method: Heat a cast-iron skillet over medium-high heat. Once hot, sear the steak for 4–5 minutes on each side. Lower the heat slightly and continue cooking until the steak reaches your desired doneness.
Sous Vide Method: Preheat your sous vide machine to 130°F for medium-rare. Seal the steak in a vacuum bag and cook for 2 hours. Finish by searing it in a hot pan to achieve a caramelized crust.

🔵 Step 4: Rest and Serve
Transfer the cooked steak to a plate and let it rest for 5–10 minutes. This allows the juices to redistribute, ensuring every bite is tender and flavorful. Slice against the grain and serve with your favorite sides.

Ingredient Additions and Substitutions

While the base recipe is simple, it’s easily customizable:

• Butter Basting: Add a pat of butter and fresh herbs to the pan during the last few minutes of cooking for extra richness.
• Smoked Paprika: Sprinkle a pinch of smoked paprika on the steak for a slightly smoky flavor.
• Marinade: For a different flavor profile, marinate the steak in soy sauce, Worcestershire sauce, and garlic for 30 minutes before cooking.

Expert Cooking Tips for Perfect Results

Achieving a flawless flat iron steak requires a combination of good technique and attention to detail. Here are some pro tips to ensure success:

Selecting the Right Cut

Look for a steak with good marbling. The fine lines of fat running through the meat ensure a juicy and flavorful steak.

Cooking Temperature Guidelines

For the perfect doneness, use a meat thermometer:

• Rare: 120–125°F
• Medium-Rare: 130–135°F
• Medium: 140–145°F
• Medium-Well: 150–155°F
• Well-Done: 160°F and above

Resting Is Key

Always let your steak rest for 5–10 minutes after cooking. This allows the juices to redistribute, resulting in a more tender and flavorful bite.

Slicing Against the Grain

When slicing the steak, cut against the grain (the direction the muscle fibers run). This shortens the fibers, making the steak easier to chew.

Enhancing the Crust

For a steakhouse-quality crust, ensure your grill or pan is very hot before adding the steak. Avoid overcrowding the pan, which can lower the temperature and prevent proper searing.

Variations to Try

Flat iron steak is versatile and works beautifully in a range of recipes. Here are some creative variations to explore:

Steak Salad

Slice the cooked steak thinly and serve it over a bed of mixed greens, cherry tomatoes, red onions, and crumbled blue cheese. Drizzle with balsamic vinaigrette for a fresh and satisfying meal.

Steak Tacos

Cut the steak into bite-sized pieces and serve in warm tortillas with pico de gallo, avocado slices, and a dollop of sour cream.

Stir-Fry

Use thinly sliced flat iron steak in a stir-fry with your favorite vegetables, soy sauce, and a hint of sesame oil for a quick and flavorful dinner.

Layer thinly sliced steak on a toasted baguette with caramelized onions, arugula, and a smear of horseradish mayo for a gourmet sandwich experience.
