Make-Ahead Colby Cheese
Breakfast Casserole

A breakfast casserole made with Colby cheese, green onions, fresh mushrooms, bread, and eggs. Serve this as part of a traditional brunch menu or as a hearty breakfast recipe.

Colby is a milder and softer cheese than cheddar and should be used fresh, as it will dry with age. When grated or sliced, this golden cheese bakes in beautifully and provides the true cheese flavor you want for a breakfast or brunch casserole.

This is a make-ahead breakfast casserole that is put together the night before, refrigerated and baked in the morning. Throw it in the oven and enjoy a cup or two of coffee with your friends or family while this bakes on its own. View more breakfast casserole recipes like this Colby cheese brunch casserole.
