Cooked hot & fast, a grilled flat iron steak is exactly what your family and friends will drool over! Add some blue cheese butter to that meat and you’ve got yourself a perfect meal…


  • Flat Iron Steak (marinade might be enough for more than one)

Balsamic Marinade

  • ¼ cup Balsamic Vinegar
  • ¼ cup Soy Sauce
  • ¼ cup Olive Oil
  • 2 Tbsp chopped Shallot
  • 1 Tbsp Brown Sugar
  • 1 Tbsp minced Garlic
  • ½ tsp Red Pepper Flakes
  • ½ tsp Salt
  • ½ tsp Black Pepper

Creamy Blue Cheese Butter

  • 1 stick Butter (softened)
  • 2 oz Blue Cheese crumbles
  • 1 Tbsp chopped Shallot
  • ½ Tbsp minced Garlic
  • 1 tsp Steak Rub

Grilled Flat Iron Steak with Blue Cheese Butter Recipe

Step one: combine the marinade ingredients, mixing them very well. Next, place the steak in a food grade zip lock bag and pour in the marinade.

Seal the bag while squeezing the air out. Then “massage” the steak through the bag to completely cover it with marinade. Place the steak in the fridge, allowing it to marinate for at least 4 hours (or overnight if possible).

This cook is fast- for this you will need a very hot coal bed (close to 500⁰F). Get your grill up and running, and while it is heating up, take a few minutes to make the blue cheese butter.

To do this, simply mix the ingredients in a small bowl. Use a fork to easily break down the butter and create a smooth mixture.

Get the steak out of the marinade, and grill it to an internal temperature of 125⁰F for medium rare.

When done, pull the steak off the heat. Immediately top with the blue cheese butter, to give it time to melt while the steak is resting.

Slice the grilled flat iron steak across the grain and enjoy!
