Slow-Cooker Beef Stroganoff

Brown meat in one tablespoon oil in a Dutch oven over medium-high heat 8 to 10 minutes. Add wine or broth to pan, stirring to loosen particles from bottom of pan. Combine flour and seasonings in a 3- to 4-quart slow cooker. Place browned meat and mixture from pan on top; toss to coat. Add mushroom soup and soup mix; stir until blended. Stir in mushrooms.

Cover and cook on high setting 3 to 3 1/2 hours or on low setting 6 to 7 hours or until meat is tender. Stir in sour cream; cover and cook until thoroughly heated. Serve over noodles tossed with butter; sprinkle with parsley, if desired.
