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

What each ingredient does

Ground chuck: Provides the browned beef base and savory flavor that carries the dish.
Frozen chopped spinach: Adds color and body; pressing out excess water keeps the sauce from thinning.
Cream of mushroom soup: Thickens the sauce and adds a creamy, savory mushroom flavor.
Sour cream: Adds tang and richness, and makes the sauce smooth and creamy.
Monterey jack cheese: Melts into the sauce for extra richness and a mild, creamy flavor.

The step that matters

Drain the spinach well. Excess water from thawed spinach dilutes the sauce and can make it thin in a slow cooker, where little liquid evaporates during cooking.
