Mom made this while we were living there, very good!
50 meatballs (frozen Costco ones or a homemade recipe)
3 tbs butter
3 c. onion, peeled and sliced
1 1/2 tbs paprika
1/2 tsp salt
1/8 tsp pepper
2 cans (10.5oz) condensed beef broth
4 tbs flour
1 1/2 c. sour cream
Heat 3 tbs butter in skillet. Add onion and saute until tender and golden brown, about 10 minutes. Add paprika, salt and pepper stirring until well blended. Stir in 1 1/2 cans of broth, bring to a boil. Add meatballs, then reduce heat and simmer, covered for 30 minutes. (Watch the meatballs, stirring occasionally to make sure the simmer doesn't turn into a boil.)
In small bowl, combine flour and remaining beef broth, whisk until smooth. Gradually add to beef mixture, stirring constantly. Simmer, uncovered stirring occasionally, 5 minutes longer.
Just before serving place sour cream in small bowl. Slowly add 1/2 cup of the hot gravy. Once smooth, slowly add to beef mixture, stirring until well blended. Heat, but do not boil.
Serve over parsley buttered noodles.
