Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes: Form the bulk of the casserole, becoming tender and soft as they bake through.
Sour cream: Adds moisture and richness, keeping the layers creamy as they heat.
Milk: Thins the sour cream so it spreads evenly and bakes into a smooth sauce.
Cheddar cheese: Melts into the layers, adding savoury flavour and a stretchy, binding texture.
Bacon: Contributes smoky, salty flavour and crisp bits that contrast with the creamy layers.
Butter: Adds richness and helps the croutons on top brown as the casserole bakes.
