Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk and starchy body that holds the casserole together.
- American cheese
- Melts into a smooth, creamy sauce that binds the potatoes.
- Mayonnaise
- Adds fat and moisture, keeping the casserole rich and tender as it bakes.
- White onion
- Adds sharp aroma and savory depth that mellows during baking.
- Bacon
- Adds smoky, salty fat and a crisp, savory topping.
The step that matters
Bake at a moderate temperature. Mayonnaise and cheese are emulsions that can separate and turn greasy if overheated. Baking at a moderate 325°F melts the cheese gently and keeps the sauce creamy and cohesive.
Swap the onion
