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

What each ingredient does

Ground beef
Provides the savory meat base that forms the body of the filling.
Dry mashed potato flakes
Absorb the hot liquid and set into a soft, spoonable topping when baked.
Egg
Binds the potato topping so it sets firm and holds its mounds when baked.
Milk
Adds moisture and richness to the potato topping for a smoother texture.
Beef gravy
Adds moisture and savory flavor that binds the filling together.
Parmesan cheese
Adds savory, salty flavor and browning to the potato topping.

The step that matters

Add the egg to the potato mixture last and blend well. Egg proteins set when heated, so the egg must be evenly mixed into the potatoes to help the topping hold its shape rather than becoming patchy or runny.
