Overnight Sausage Casserole Recipe
This overnight sausage casserole recipe is an easy make-ahead breakfast for a crowd. You whisk eggs with half-and-half, combine with browned sausage, then let it rest in the fridge so it bakes up evenly in the morning.
Ingredients
For the casserole
Step-by-Step Method
Preheat and grease
Heat the oven to 350°F (180°C). Grease a baking dish with butter so the casserole releases cleanly.
Brown the sausage
Cook the sliced sausage in a skillet over medium heat for 4–6 minutes, just until lightly browned. If there’s extra fat, blot briefly with paper towels.
Whisk the egg base
Whisk the eggs in a large bowl. Pour in the half-and-half, add the salt, and mix until smooth.
Assemble and chill overnight
Spread the sausage in the baking dish and pour the egg mixture over it. Cover and refrigerate for at least 8 hours (overnight) so it bakes more evenly.
Bake
Uncover and bake for 30–35 minutes, until the center is set and the top is lightly golden. If the top browns too fast, tent with foil for the last 10 minutes.
Rest and serve
Let it sit for 5–10 minutes, then slice and serve warm. It’s nice with simple greens or fresh tomatoes.
