Time 20m

Number Of Ingredients 8

1 tablespoon safflower oil, plus more if needed
4 boneless New York strip (shell) steaks (6 ounces each), 1/2-inch thick
Coarse salt and freshly ground pepper
1/4 pound cremini mushrooms, cut into 1/4-inch-thick slices
1/4 pound shiitake mushrooms, cut into 1/4-inch-thick slices
1 cup homemade or store-bought low-sodium chicken stock
2 teaspoons Dijon mustard
1 tablespoon chopped fresh herbs (such as parsley, thyme, or chives), for garnish

Steps:

Heat oil in a 12-inch skillet over medium-high heat. Season both sides of each steak with salt and pepper. Cook 2 steaks at a time for 1 1/2 minutes per side for medium-rare. (Do not flip steaks more than once.) Add more oil if needed. Transfer to a plate. Cover, and let rest at least 5 minutes.
Add mushrooms to drippings in skillet, and cook over medium-high heat, stirring occasionally, until tender, about 4 minutes. Add stock and juices from plate to skillet. Bring to a boil, scraping up brown bits. Stir in mustard, and simmer until sauce lightly coats the back of a spoon, about 3 minutes. Pour sauce over steaks, and sprinkle with herbs.
