This is the easiest balsamic steak marinade you will ever make. Convenient to make with things you already have in your pantry, it will become your go to marinade.
In a bowl, combine garlic, oil, balsamic vinegar, beef broth, herbs and salt and pepper.
Pour into a resealable plastic bag and add steak. Shake to coat and refrigerate for 8 hours or overnight.
Heat grill to medium high heat.
Grill steak on each side for 5-6 minutes for medium. Use a thermometer to check temperature.
Steak will continue to cook once it is removed from grill.
Remaining sauce can be heated in a pan and boiled until reduced to 1/2 and then spooned over top if desired.
Notes
To get those great grill marks on. your steak, rotate it 1/4 turn halfway through the cooking process. You'll get those great criss cross marks!
I always undercook my steaks about 5 degrees or so and then remove them and let them sit for five minutes, the meat will continue to cook.
I think this balsamic marinated steak is best if cooked to a medium or medium rare temperature. You can cook it more well done but it wil lbe less flavorful.
You can also use this marinade with grilled veggies. Just coat the veggies before grilling. It is also delicious as a salad dressing.
