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

What each ingredient does

Eggs: Bind the rice and cheese mixture and set into a firm, sliceable bake.
Rice: Provides the bulk and starchy body that holds the filling together.
Monterey jack cheese: Melts into the filling, adding richness and helping bind it together.
Ground beef: Supplies savory, browned meat flavor and substance to the filling.
Frozen chopped spinach: Adds vegetable body and earthy flavor to the filling.
Milk: Adds moisture and softness to the egg custard that sets the bake.

The step that matters

Bake until set. Eggs set as they heat, and pulling the dish too early leaves a loose, wet center that will not hold clean squares. Baking until set ensures the custard firms throughout.
