In a large bowl, mix thoroughly ¼ cup soup, lamb, bread crumbs, onion and egg. Shape firmly into 4 patties of even thickness. Put patties on a plate and refrigerate for 1 hour to help solidify.
In a separate bowl, mix the soup, milk, salt, pepper, Worcestershire sauce, and mushrooms. Set a side.
In a large skillet over medium-high heat; warm the oil. Season both sides of the patties with salt and pepper. Cook the patties until browned, about 3 to 4 minutes on each side. Remove patties to a plate and keep warm.
In the same skillet, add the soup mix. Heat to low simmer. Return patties to skillet. Cover; simmer for 20 minutes.
