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

What each ingredient does

Lean ground beef: Provides the main protein and savory body of the filling.
Zucchini: Adds moisture and tender-crisp vegetable texture to the casserole.
Cooked rice: Bulks out the casserole and absorbs juices from the filling.
Monterey jack cheese: Melts into the filling and browns on top for richness and color.
Sour cream: Adds creaminess and moisture to the mixture.

The step that matters

Cook the beef and zucchini until tender crisp. Zucchini releases a lot of water when heated. Cooking it briefly over medium-high heat, with the beef browned, keeps it from turning mushy and watering down the casserole during baking.
