Why Choose Flat Iron Steak?

The flat iron steak, also known as butlers steak or oyster blade steak, is celebrated for its exceptional flavor and tenderness. It is cut from the shoulder of the cow and is characterized by its rich marbling. This cut is perfect for grilling due to its relatively even thickness, which ensures a uniform cook. When seasoned and grilled correctly, the flat iron steak can rival more expensive cuts, making it a favorite among steak lovers.

Preparation: Marinating the Flat Iron Steak

Preparation is key when it comes to grilling any steak. A well-marinated flat iron steak can make all the difference. Heres a step-by-step guide:

  1. Choosing the Steak: Look for a flat iron steak with good marbling and an even thickness.
  2. Marinade Ingredients: Gather ingredients such as olive oil, garlic, soy sauce, Worcestershire sauce, black pepper, and fresh herbs.
  3. Marinating Process: Combine the ingredients in a bowl. Place the steak in a resealable plastic bag and pour in the marinade. Seal the bag and refrigerate for at least 2 hours, or preferably overnight.

Setting Up Your Charcoal Grill

Proper grill setup is crucial for achieving a well-cooked steak. Follow these steps for a flawless setup:

  1. Lighting the Charcoal: Use a chimney starter to light the charcoal evenly. For a step-by-step guide, check out this charcoal guide. Once the coals are covered with a white ash, theyre ready to use.
  2. Setting Up the Grill: Arrange the coals on one side of the grill for direct heat and leave the other side for indirect heat. This two-zone setup allows for better control during grilling.
  3. Preheating the Grill: Place the cooking grate on the grill and close the lid. Allow the grill to preheat for about 10-15 minutes, ensuring it reaches a high temperature.

Grilling the Flat Iron Steak

Now that your grill is ready, its time to cook the steak. Heres a step-by-step guide:

  1. Searing the Steak: Place the marinated steak directly over the coals for a hot sear. Sear for 3-4 minutes on each side to develop a flavorful crust.
  2. Finishing the Steak: Move the steak to the cooler side of the grill to finish cooking. Use a meat thermometer to check the internal temperature. For medium-rare, aim for 130-135F.
  3. Resting the Steak: Once cooked to your desired doneness, remove the steak from the grill and let it rest for 5-10 minutes. This allows the juices to redistribute, resulting in a juicy steak.

Serving Suggestions

Your perfectly grilled flat iron steak deserves equally delicious sides. Here are some excellent pairings:

  • Grilled vegetables such as asparagus, bell peppers, or zucchini.
  • A fresh salad with a light vinaigrette dressing.
  • Classic mashed potatoes or a baked potato for a hearty addition.
  • Frozen Broccoli
  • Salmon Fillet
