Flavor Grilled Steak and Vegetables with Fresh Herb Butter

Last updated September 7, 2023
Add a gourmet touch to your grilled steaks with a pat of butter flavored with fresh herbs from your garden. This simple trick is called compound butter. It's is reason enough to keep a few pots of herbs on your deck or patio through grilling season. This guide will show you how to flavor grilled steak and vegetables with fresh herb butter.
The method is easy, but not last-minute. Remove butter from the refrigerator. Let it come to room temperature until it’s soft enough to work in chopped herbs and flavorings.
Take your pick from the easy-to-grow herbs at hand, like parsley, thyme and tarragon. Lemon zest and finely chopped garlic can be delicious add-ins. Finish with salt, if you used unsalted butter, and a grind of fresh black pepper.

Flat Iron Steaks With Herb Butter and Grilled Broccolini Recipe

INGREDIENTS:
- 4 flat iron steaks, each 6 to 8 ounces and about 1-inch thick, excess fat and any gristle removed
- Extra-virgin olive oil
- Kosher salt
- Freshly ground black pepper
- 1 pound broccolini, with stalks no wider than ½ inch
- 1 teaspoon crushed red pepper flakes
- 1 recipe Herb Butter
INSTRUCTIONS:
- Lightly brush the steaks on both sides with oil and season evenly with salt and pepper. Allow the steaks to stand at room temperature for 15 to 30 minutes before grilling. In a large bowl of water, submerge the broccolini for 20 to 30 minutes so that they absorb water. This will help them steam a little on the grill.
- Prepare the grill for direct and indirect cooking over high heat, 450° to 550° degrees Fahrenheit.
- Pour off the water from the bowl of broccolini. Lightly drizzle some oil over the broccolini and season with salt and the red pepper flakes. Toss to coat evenly.
- Brush the cooking grates clean. Grill the steaks over direct high heat, with the lid closed as much as possible, until cooked to your desired doneness, 6 to 8 minutes for medium rare, turning once or twice. If flare-ups occur, move the steaks temporarily over indirect heat. Remove from the grill and let rest while you grill the broccolini.
- Using tongs, lift the broccolini and allow any excess oil to drip back into the bowl. Grill the broccolini over direct high heat, with the lid closed as much as possible, until lightly charred, 3 to 4 minutes, turning occasionally. Finish cooking over indirect high heat for 2 to 3 minutes.
- Cut four 1/2-inch-thick pieces of herb butter and place one in the center of each steak. Serve warm with the broccolini.
