Slow Cooker Beef Stroganoff

2	pounds beef stew meat
1	cup chopped onion
1	can (10 3/4 ounces) condensed cream of golden mushroom soup
1	can (10 3/4 ounces) condensed cream of onion soup
1	jar (6 ounces) Green Giant® sliced mushrooms, drained
1/4	teaspoon pepper
1	package (8 ounces) cream cheese, cubed
1	container (8 ounces) sour cream
6	cups hot cooked noodles or rice

	In 3 1/2- to 4 1/2-quart slow cooker, mix beef, onion, soups, mushrooms and pepper.
	Cover and cook on low heat setting 8 to 10 hours or until beef is very tender.
	Stir cream cheese into beef mixture until melted. Stir sour cream into beef mixture. Serve over noodles. I sometimes use hamburger if I don't have stew meat. I tastes just as good and is sometimes less expensive.
