Scalloped Potatoes For A Crowd

Preheat the oven to 325 degrees F. Grease 8-quart capacity baking pans (for 100 servings you'll need 3 pans - adjust accordingly if you change the serving size).

Heat the milk in a large stockpot or dutch oven over medium heat. Do not let it boil. Add the butter, salt, and pepper. Cook, stirring constantly, until the butter has melted. Reduce the heat to the lowest setting and keep warm

Peel and slice the potatoes 1/4-inch thick (a mandoline works well for this task).

Place some of the cream sauce mixture in the bottom of each baking pan. Top with a layer of potatoes. Lightly salt the potatoes then repeat the layering.

Place the baking pans in the oven and bake at 325 degrees F for 2 hours or until the potatoes are tender. If the potatoes start to brown too much, cover lightly with foil.

Serve the scalloped potatoes warm.
