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

What each ingredient does

Butter: Enriches the sauce and carries flavor while it cooks with the flour.
Flour: Thickens the milk and broth into a smooth sauce that holds the casserole together.
Milk: Forms the creamy body of the sauce along with the broth.
Cooked long-grain rice: Adds bulk and a tender grain texture that soaks up the sauce as it bakes.
Chicken: Provides the main protein and substance of the dish.
Mushrooms: Add moisture and savory, earthy flavor as they release liquid in the sauce.

The step that matters

Gradually stir in milk and broth. Adding the liquid slowly while stirring keeps the flour dispersed, so the sauce thickens smoothly instead of forming lumps.
