4 servings (serving size: 1 steak and about 1/4 cup sauce)

Jazz up frozen mashed potatoes by drizzling them with a bit of truffle oil for a quick but impressive side to accompany this easy dish. Place fresh green beans in a bowl with a little water. Microwave 3 minutes or until the beans are done.

How to Make It

Step 1

Sprinkle beef with salt and pepper. Melt 1 teaspoon butter in a large nonstick skillet over medium-high heat. Add beef to pan; cook 3 1/2 minutes on each side or until desired degree of doneness. Remove beef from pan; keep warm.

Step 2

Melt remaining 1 teaspoon butter in pan. Add mushrooms, shallots, and garlic to pan; sauté 3 minutes. Stir in broth and sherry. Combine cornstarch and 2 teaspoons water in a bowl, stirring until smooth. Add cornstarch mixture to pan; bring to a boil. Cook 1 minute, stirring constantly.

I made this sauce tonight and it was fabulous. I did add about 1/2 of a small onion chopped, used 3 cloves of fresh garlic minced and a few sprigs of fresh gooood!!!

Very easy. Used strip steak because it was on sale. Made the mushrooms earlier in the day up to the point of adding the cornstarch. Let the beef rest covered while the potatoes & brussels sprouts finished & added the accumulated juices and some fresh thyme to the mushrooms before thickening. Pretty good.

This is the second time I have made this recipe, had to cook the steak a bit longer, added it back at the end, so it soaked up some of the sauce! Excellent, served with asparagus broiled with parmesan cheese and pine nuts and a baked potato. YUM!

My husband, inlaws and I loved this recipe (we made no alterations). It's one of the best meals we've made in a long while. Thanks Cooking Light! We will make this on a regular basis. We served the steak with ceasar salad & butter & herb rice.

This was bland and didn't do anything for the flavor of the steak. We didn't even eat it all and we LOVE mushrooms. Also, I will never pan cook a filet again. Not good. Will not make again.

Really easy, elegant and absolutely delicious. The first time I tried this was for a romantic Valentine's Day dinner, but since, I make it anytime filet mignon or beef tenderloin go on sale. Mmmm!
