This make-ahead Tater Tot Breakfast Casserole features a savory blend of crispy tater tots, seasoned sausage, and colorful bell peppers, all bound together with a rich, cheesy egg custard. Prepared the night before and baked until golden and bubbly, it offers a comforting, hearty dish perfect for a crowd at breakfast or brunch with minimal morning effort.
For optimal flavor integration and a firmer set, ensure the casserole is refrigerated overnight; this allows the egg mixture to fully absorb into the tater tots. When browning the sausage and onions, aim for good caramelization on the onions to build a robust flavor foundation. For a crispier bottom layer, you can slightly pre-bake the tater tots for 10-15 minutes before adding other ingredients, or ensure they are well-drained of any excess moisture. Don't be shy with seasoning; adjust salt and pepper to taste in the egg mixture, and a touch more cayenne or a pinch of smoked paprika could elevate the overall profile.
