Brunch Strata

A cheesy brunch casserole that is great for a crowd. It is prepared the night before and baked just before serving.

1 pound Loaf Sourdough Bread -- sliced
2 tablespoons Butter -- softened
1 1/2 pounds Sharp Cheddar -- shredded (6c)
12 Large Eggs
1 teaspoon Dry Mustard
1 teaspoon Salt
4 cups Milk
1 jar Apricot Preserves

Cut crust from bread. Butter slices lightly on one side. Cut into cubes and set aside. Blend remaining ingredients (except apricot preserves) in blender. Arrange half of bread cubes in bottom of well buttered 10x16x2 inch glass baking dish. Pour half of milk mixture over bread. Arrange remaining bread cubes on top. Pour remaining milk mixture over it. Cover and refrigerate overnight. Bake, uncovered, in a preheated 350 degree oven for 1 hour or until puffy and brown. Serve with apricot preserves.
