Grilled Flat Iron Steak with Blue Cheese Butter

Follow our step-by-step guide on how to make Grilled Flat Iron Steak with Blue Cheese Butter.

1. Step 1

   Start by creating a flavorful marinade that will elevate your flat iron steak.

2. Step 2

   In a mixing bowl, combine olive oil, red wine vinegar, minced garlic, a tablespoon of cracked black pepper, dried rosemary, dried oregano, and kosher salt.

3. Step 3

   Whisk these ingredients together until they’re perfectly blended.

4. Step 4

   Next, pour this delicious marinade into a resealable plastic bag.

5. Step 5

   Add the flat iron steak to the bag, making sure it gets thoroughly coated in that savory mixture.

6. Step 6

   Squeeze out any excess air, seal the bag tightly, and let it marinate in the refrigerator for about 30 minutes.

7. Step 7

   This step is crucial for infusing the steak with flavor, so don’t rush it! While the steak is soaking up those tasty juices, preheat your outdoor grill to medium-high heat and give the grill grate a light oiling to prevent sticking.

8. Step 8

   Once the marinating time is up, take the steak out of the bag, shaking off any extra marinade, and discard the leftover marinade.

9. Step 9

   Allow the steak to rest at room temperature while your grill reaches the perfect cooking temperature.

10. Step 10

    Meanwhile, let’s whip up a delightful blue cheese-chive butter.

11. Step 11

    In a separate bowl, mash together softened butter, crumbled blue cheese, chopped chives, and a pinch of cracked black pepper until everything is well combined.

12. Step 12

    This creamy topping will add a rich finish to your steak.

13. Step 13

    Now, it’s time to grill! Place the steak on the preheated grill and cook it for about 5 minutes on each side.

14. Step 14

    You’re looking for a firm texture with a juicy, reddish-pink center.

15. Step 15

    For those who like to be precise, an instant-read thermometer should read 130°F (54°C) for that perfect medium-rare.

16. Step 16

    Once the steak is cooked to your liking, remove it from the grill and let it rest in a warm spot for about 10 minutes.

17. Step 17

    This resting period allows the juices to redistribute, ensuring every bite is tender and flavorful.

18. Step 18

    When you’re ready, slice the steak thinly against the grain for maximum tenderness.

19. Step 19

    Serve it up with a generous dollop of your homemade blue cheese-chive butter on top, and enjoy the mouthwatering flavors of your perfectly grilled flat iron steak!.
