For the Steak

2 USDA Prime Dry-Aged Bone-In Rib Steaks (16 oz. each)
2 tsp kosher salt
1 tsp black pepper

For the Garlic Herb Sauce

4 tbsp unsalted butter
2 tbsp olive oil
1 shallot (chopped)
6 cloves garlic (minced)
2 springs rosemary (chopped)
1/4 cup parsley (chopped)
1/4 cup tarragon (chopped)
1/4 cup cilantro (chopped)
1/4 cup mint (chopped)
2 lemons (juice of)
1/4 tsp smoked paprika

How to Make Grilled Flank Steak with Lemon-Herb Sauce

Step 1: Prepare the Steaks

Pat dry the steaks very well on both sides. Season them with half of the kosher salt and black pepper. Let the steaks sit on the board for a few minutes to absorb the flavors.

Step 2: Preheat Your Grill

Prepare your grill by waiting until the charcoal briquettes become hot and ashy. This ensures an even cooking temperature when grilling.

Step 3: Make the Garlic Herb Sauce

In a pan over medium heat, combine the unsalted butter and olive oil. Once melted, add in chopped shallots and minced garlic. Cook until they are translucent and aromatic.

Step 4: Add Fresh Herbs

Remove the pan from heat and stir in chopped rosemary, parsley, tarragon, cilantro, mint, remaining salt, pepper, lemon juice, and smoked paprika. Mix well and set aside.

Step 5: Grill the Steaks

Once your briquettes are very hot, carefully move them to one side of the grill for direct and indirect heat cooking. Cut a potato in half and rub it on the grates to help prevent sticking.

Step 6: Sear the Steaks

Place steaks on direct heat. Sear each side for about 4 minutes. After searing, transfer them to indirect heat for another 4 minutes per side until they reach an internal temperature of 135°F for medium doneness.

Step 7: Rest and Serve

Remove steaks from heat and let them rest on a cutting board for about 10 minutes. After resting, slice against the grain and serve topped with garlic herb sauce. Enjoy your delicious grilled flank steak!

Using Too High Heat: Cooking on too high heat can char the outside while leaving the inside undercooked. Balance direct and indirect heat for even cooking.
