After you remove the sauce from the heat, stir in one cup of shredded cheddar cheese until melted. Then, follow the recipe as directed, making the two layers and baking the casserole.

Scalloped Potatoes and Ham

Divide 1 1/2 cups of diced ham between the layers (3/4 cup on the bottom layer and 3/4 cup on the top layer). Then, bake as directed.

Better with Bacon

Add between 1/2 to 1 cup of cooked bacon crumbles to the casserole.

Add More Onion

Divide one cup of thinly sliced onions between the bottom and top layer. Bake as directed.

Storage

Allow the dish to cool and cover it with plastic or transfer it to an airtight container and store it in the fridge for up to 3 days or transfer it to a freezer-safe container and store it in the freezer for up to 2 months.
