This crustless breakfast casserole is packed with savory sausage, gooey cheddar, and fluffy eggs. It’s a simple, crowd-pleasing dish perfect for holidays, lazy Sundays, or breakfast for dinner.
For best results, use room temperature eggs and whole milk. Shred cheese from a block for smoother melting. Let sausage cool before layering to prevent curdling. If making ahead, assemble the night before and refrigerate; add 5-10 minutes to baking time. For a keto adaptation, replace milk with unsweetened almond milk or heavy cream and add 1/4 cup softened cream cheese.
