Flat Iron Steak with Mushrooms
Ingredients
3 (6 oz.) flat iron steaks
Salt and pepper to taste
3 Tbsp oil
3 shallots, thinly sliced
6 cloves garlic, peeled
4 cups sliced mushrooms
¼ cup balsamic vinegar
¾ cup full bodied red wine
Preparation
Heat oil in skillet over medium heat. Season both sides of steak. Sear until browned on each side (about 2-3 minutes). Remove from skillet and place in oven proof dish. Place in preheated 350° F oven to continue cooking while cooking mushrooms.
Â
Add shallots and whole garlic to hot skillet. Cook and stir until shallots start to brown. Add mushrooms to pan; cook and stir until they shrink (about 5-10 minutes).
Â
Pour the vinegar into the pan and stir to remove bits on the pan bottom. Pour in the wine and simmer over medium heat (about 5 minutes).
Â
Return the steaks to the skillet and cook until the internal temperature reaches 135-140° F. Remove from heat and let rest until the steaks reach 145° F or your desired doneness.
