Preheat the oven to 325°F (165°C) and grease a 9x13 inch baking dish. Boil sliced potatoes until tender but still firm, then drain and combine them in a bowl with cheese, onion, mayonnaise, salt, pepper, bacon, and olives. Finally, bake the mixture in the preheated oven for an hour until golden brown.

A list of ingredients never explains the physical friction between starches and dairy at 325 degrees Fahrenheit. Mayonnaise breaks down under prolonged heat, releasing its oil if the emulsion fails. To counteract this, slice medium potatoes uniformly to two-thirds of an inch thick so they withstand both boiling and baking without turning into pure starch. Processed American cheese melts completely because of its emulsifying salts, binding the loose starches together while the dish spends sixty minutes in the oven.
Boil the sliced potatoes for exactly ten minutes in salted water before draining them thoroughly in a colander. Residual moisture prevents the mayonnaise and cheese from adhering correctly to the potato surfaces. Cook the half-pound of sliced bacon in a deep skillet over medium-high heat until crisp, then drain it completely on paper towels to eliminate excess grease that would otherwise pool inside the nine-by-thirteen-inch baking dish.
