Savory Herb Steak Marinade

Why This Savory Herb Steak Marinade Works

Once the steak sits in the marinade, the liquid starts to move in and out of the meat. Soy sauce and Worcestershire sauce loosen up the muscle fibers a bit, so the steak doesn’t tighten as much on the grill. Olive oil coats the outside, so when the steak hits the hot pan or grill, the surface doesn’t dry out right away. Balsamic vinegar is a mild acid, so it gently softens the outer layer instead of turning it mushy.

During the long rest in the fridge, garlic, rosemary, thyme, and mustard spread through the outer part of the steak. They don’t go all the way to the center, but they soak into the surface enough that every bite near the edge tastes seasoned. As the steak cooks, that oiled, seasoned outside browns faster and forms a crust, while the inside stays juicy. After cooking, the short rest lets the hot juices settle back into the meat instead of running out on the cutting board.

Mistakes To Avoid

Letting the steak sit in the marinade for days instead of just a few hours or overnight can make the outside mushy. The acid from the balsamic and the salt from the soy and Worcestershire start breaking down the surface too much, so the meat loses its firm bite and feels a bit pasty when sliced.

Cooking the steak straight from the fridge without letting it warm up slightly often leads to a burnt outside and a cold or underdone center. The pan or grill has to stay on the heat longer to catch up the middle, so the surface dries out and tightens while the inside is still catching up.

Pouring the leftover marinade into the pan or over the steak while it finishes cooking can cause problems. The liquid steams instead of sears, so the steak stops browning and the outside turns gray and wet, and any garlic in the liquid can burn in patches and leave bitter, charred spots.
