Ingredients

1 beef rib eye roast (5-pound), 2 or 3 ribs

2 teaspoons whole black peppercorns, cracked

4 teaspoons fresh thyme leaves, divided

1 cup sour cream

¼ cup Kraft prepared horseradish

1 teaspoon sugar

1 tablespoon butter

1 sweet onion, very thinly sliced

1 package (8-ounce) sliced fresh mushrooms

1 tablespoon flour

1 cup fat-free reduced-sodium beef broth

1 tablespoon Grey Poupon Dijon mustard

Heat oven to 350 degrees F.
Place meat, fat-side up, in roasting pan. Press peppercorns and 2 teaspoons thyme onto surface of meat. Bake 2 to 2¼ hours or until 135 degrees F. (To check for doneness, insert probe of instant-read thermometer 2 to 2½ inches into thickest part of meat.) Meanwhile, mix sour cream, horseradish and sugar in serving bowl. Refrigerate until ready to serve.
Remove meat from oven. Cover meat with foil; let stand 15 to 20 minutes or until medium-rare doneness (145 degrees F).
Meanwhile, melt butter in large skillet on medium heat. Add onions; cook and stir 8 to 10 minutes or until golden brown. Add mushrooms; cook and stir 6 minutes or until tender. Sprinkle with flour; cook and stir 1 minute. Stir in broth; simmer 5 minutes or until thickened, stirring constantly. Remove from heat; stir in mustard and remaining thyme.
Slice meat. Serve with sauces.
