Creamy Salisbury Steak

I wanted to learn how to make my own Salisbury steaks, so I googled it and found this recipe. I wasn't thinking when I made it the first time and made the whole recipe which made about 9 patties!! WAY to much for my small family, so next time I will 1/2 the recipe!

I found this recipe at realmomkitchen.com

2 pounds ground beef
1 package Onion Soup Mix
1/2 cup cracker crumbs
1 egg
2 packets (0.75 oz) brown gravy mix
1 cup sour cream
1 small can mushroom stems, optional
egg noodles, rice or mashed potatoes (I always do mashed potatoes)
Make hamburger patties using ground beef, bread or cracker crumbs, egg and soup mix. Fry or grill until patties are browned on both sides.
While the hamburgers are cooking, mix together the brown gravy the the water required on the package and whisk in the sour cream.
Spray a 9 x 13 pan with nonstick and lay cooked patties in the pan. Cover the patties with the sour cream and gravy mixture.
Bake at 350 degrees covered for 30 – 40 minutes, turning patties halfway through. Serve with egg noodles, rice or mashed potatoes.
