I've made this recipe since the 70's and it's still a family favorite after all these years.  Serve it with mashed potatoes, corn, hot rolls and coleslaw and it's comfort food at it's finest.  

1 (10 1/2 ounce) can Campbell's Condensed Golden Mushroom Soup, divided, you only use 1/4 cup in the Salisbury steak, the rest you. mix with water for the gravy.

1 1⁄2 lbs ground round - I used chuck

1 ⁄2 cup plain dry breadcrumbs

1 large egg, beaten

1 ⁄2 cup chopped onion

salt and pepper

garlic powder - about 1/2 tsp.

1 ⁄3 cup water

Steps

Sauce onion in a tablespoon of olive oil until soft.  If you omit this step they can be crunchy

Combine 1/4 cup of the can of soup with ground beef, bread crumbs, egg, onion, salt, pepper, and garlic salt; mix well.

Shape into 6 patties.

Place in shallow baking dish.  I line with parchment paper for easy cleanup. 

Bake at 350 degrees for 30 minutes.

Drain off fat, if needed

Combine remaining soup and the 1/3 cup water; pour over patties.

Bake an additional 10 minutes or until thoroughly heated.

Notes

We like a lot of gravy so I use an additional can of Golden Mushroom Soup, not listed above.  I add 1/3 cup water to the soup, warm it in a saucepan and pour over the potatoes when we serve it.
