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

What each ingredient does

Egg noodles: Provide the starchy base that holds the creamy sauce together in the casserole.
Butter or margarine: Adds fat and richness, carrying the flavor of the sautéed onion and green pepper.
All-purpose flour: Thickens the milk into a smooth sauce that binds the casserole.
Milk: Forms the liquid base of the sauce, which thickens as it heats.
Parmesan cheese: Adds savory, salty flavor and browns lightly on the baked topping.
Diced cooked tofu: Supplies protein and a soft texture that replaces the meat in the casserole.

The step that matters

Cooking the milk into the roux. Adding milk gradually while stirring constantly keeps the flour smooth and lets the sauce thicken evenly. Adding it all at once or stopping stirring can leave lumps.
