1 can (10 ounce size) cream of mushroom soup, undiluted
2 pounds ground beef
1 envelope (1 ounce size) dry onion soup mix
1/2 cup dry bread crumbs
1 egg, beaten
1/4 cup water
Preheat the oven to 350 degrees F.
In a large bowl, combine half of the cream of mushroom soup, the ground beef, onion soup mix, bread crumbs, and beaten egg. Mix well and pat the mixture into a 4-inch x 8-inch loaf. Place the meatloaf in a baking dish.
Place the baking dish in the oven and bake for 1 hour 15 minutes or until done. Drain the grease but reserve the drippings for the sauce. Set the meatloaf aside with a foil cover over the top.
In a saucepan, combine the remaining soup, water, and reserved drippings and heat over medium heat until boiling. Stir well and thin if needed with additional water.
Slice the meatloaf and serve the mushroom soup sauce over the individual portions.
