Breakfast Chicken and Sausage Strata — Savory Casserole for Brunch

This Breakfast Chicken and Sausage Strata is a deliberately old-school, very forgiving casserole that marries two savory proteins — shredded rotisserie chicken and seasoned breakfast sausage — with sharp cheddar and a silky egg-milk custard. The trick is contrast: day-old crusty bread soaks just enough of the custard to become custardy in the center while still offering a lightly crisp, cheesy crown. Browning the sausage with the onion develops the browned, caramelized notes that keep the strata from tasting flat, and the parsley brightens each bite so it never feels heavy.

Built for company and chaos-free mornings, this strata rewards a little advance work — assemble it the night before to let flavors meld, or pull it together the morning of for fresher texture. It slices cleanly into squares that reheat well, making it ideal for brunch crowds, potlucks or busy weeknight dinners when you want comfort without fuss. Small swaps in cheese, herbs, or sausage give you a reliable template to tailor heat, richness, and seasoning to your table.
