If the breadcrumbs are prepared, use 1 quart of bread crumbs per 50 servings.   

To make the breadcrumbs, toast the hamburger buns in a low temperature oven (200 degrees F) until slightly golden brown and firm. Cool before preparing the crumbs.
Break the buns into pieces and place them in a food processor or appropriate grinder. Process the bread until the desired crumb size is obtained. See recipe MRS 1303, Whole Wheat Bread Crumbs, for detailed directions and photographs of this recipe.


Spray the pans with food release spray. Divide the potatoes among the pans with about 1 quart of potatoes for each steamtable pan (12" x 20" x 2½") For 50 servings use 2 steamtable pans. 


Sprinkle the onions evenly over potatoes. For dehydrated onions, use 1 ounce (1/2 cup) per pan.


Heat the water to rolling boil.


Combine the flour, dry milk, salt, and pepper. Then slowly add the mixture to the boiling water while whipping until it is smooth.


Add the cheese to sauce and whip until it  is well blended.


Pour 3 quarts the cheese sauce over each steamtable pan. Stir to combine the cheese sauce and the potatoes.


For the topping:

  • Combine the melted margarine and bread crumbs.
  • Mix well to to coat the crumbs.
  • Reserve the breadcrumbs for step 9.


Bake until evenly golden brown on top:

Conventional Oven: 350 degrees F for 45 minutes to 1 hour.
Convection Oven:     300 degrees F for 35 to 45 minutes.

After 25 minutes, sprinkle approximately 2 cups of bread crumbs evenly over each pan. Return the pans to the oven to complete the baking process.
