This savory, comforting casserole is the perfect weekend breakfast or brunch. It combines browned sausage, eggs, cheese, and bread in a simple, make-ahead dish that feeds a crowd with minimal effort.
For a make-ahead option, assemble the casserole, cover, and refrigerate overnight. Let sit at room temperature for 20-30 minutes while the oven preheats before baking. Use day-old or toasted bread for best texture. Leftovers reheat well.
