Overnight Egg Sausage Casserole ingredients
- Sausage – use a classic breakfast sausage, I use a local brand, Neese’s, but any breakfast sausage will work. You could also substitute Italian sausage.
- Brie – this is the star of the recipe, you do not need to remove the outer casing, it’s meant to be eaten with the cheese.
- Bread – Any type of day old bread will work well in this recipe. If the bread is fresh, just toast it in the oven for a few minutes to dry it out.
- Parmesan cheese – a little freshly grated parmesan cheese adds a great flavor.
- Heavy Cream – Do not substitute milk for the cream or this casserole will lose it’s custard texture.
- Pantry staples – Grab milk, eggs, fresh thyme and dry mustard.
What is brie cheese?
Brie is named after a region in France where it originated. It is a soft cheese traditionally made with cow’s milk, with an outer coating of white mold that is meant to be eaten with the interior cheese. While it is great with crackers, you’ve got to try it in this breakfast casserole.
Pro tip: If your bread is fresh, toast it in the oven for a few minutes to dry it out. This will make it absorb the liquids better.
How to make Sausage Breakfast Casserole Overnight
Step 1: Cook the sausage
Cook the breakfast sausage and make sure to drain any excess grease.
Step 2: Prepare the pan
Place the bread on the bottom of a baking dish then top with sausage, brie, and parmesan.
Step 3: Beat it!
Beat 5 of the eggs with 2 cups of the milk and cream mixture and pour it over the sausage mixture. Save the rest of the eggs and milk to add right before baking.
Step 4: Chill out
Cover the casserole dish with plastic wrap and refrigerate overnight.
Step 5: Bake!
Top the casserole with the remaining eggs and cream the next morning. This makes it custardy all the way through and not just at the bottom.
Bake until set and serve warm.
Why do you refrigerate Sausage Egg Bread Casserole before baking?
When you refrigerate an egg casserole, it allows the egg and milk mixture to be absorbed into the bread.
How long can this Sausage Egg Bread Casserole sit in the fridge before baking?
You can let this sausage breakfast casserole recipe sit in the fridge for up to 24 hours before baking. I would not let this casserole sit for longer than 24 hours in the fridge as the bread will turn to mush.
Overnight Sausage Breakfast Casserole FAQs
Can you eat the rind of brie?
Yes, the rind of brie cheese is meant to be eaten. It adds a subtle mushroom like flavor to the cheese and compliments the interior cheese.
Does breakfast casserole have to sit overnight?
Sitting overnight allows the egg mixture to soak into the bread, without this step you would have layers of eggs and bread and sausage.
Why is my breakfast casserole soggy?
If the casserole is soggy, it needs to bake longer,make sure the middle is set before removing from the oven.
What’s the difference between a frittata and a breakfast casserole?
A frittata is simply eggs along with veggies and/or meat that has been baked. It is not custardy and does not contain bread like a breakfast casserole.
Can you put a casserole dish straight from fridge to oven?
It is best to let a casserole come to room temperature before putting in the oven. If the casserole is cold or frozen, it will affect the cooking time. Also some casserole dishes can not withstand that drastic change in temperature and could crack.
How to serve Overnight Sausage and Egg Casserole?
- Something sweet like these peach cinnamon roll is great with this savory breakfast.
- Blueberry muffins or pear muffins would be a great combo.

- Nothing beats a side of hash browns at breakfast.
- Since it already has meat, it’s pretty filling all by itself. However, a simple fruit salad pairs well with the savory sausage.

Barbara’s Tips + Notes
- For the casserole to be custardy you will need cream or half-and-half.
- You can Italian sausage instead of breakfast sausage.
- If you’re bread is not day old, then toast it slightly in the oven to dry it out, it will absorb the cream better if it is dry.
