What is a sausage and egg breakfast casserole?
A casserole is a cohesive, one-dish meal prepared in a casserole pan and slowly baked in the oven.
A sausage casserole, also known as a breakfast casserole or bake, is a simple, hearty American dish commonly served for breakfast or brunch.
Sausage breakfast bakes are traditionally made with eggs, milk, cheese, sausage (or other meats), and vegetables. Breakfast casseroles can also include cubed bread, shredded potatoes (hash browns) or biscuits.
How to make breakfast sausage and egg casserole?
This egg breakfast casserole with sausage and veggies is incredibly easy to make and only requires 20 minutes of hands-on preparation!
- Saute the vegetables: In a large skillet, heat olive oil over medium-high heat. Add the onion, peppers and season generously with salt and pepper. Cook, stirring occasionally until soft.
- Add the sausage: Add the sausage and cook, breaking up any large pieces with the back of a spoon, until no longer pink. Stir in the pepperoni and season again to taste. Remove from heat and let cool completely.
- Grease a 9×13’’ baking dish with non-stick cooking spray. Set aside.
- Prepare the egg custard: In a medium bowl, beat the eggs with milk, mustard, salt and pepper. Set aside.
- Mix the filling: In a large bowl, add the bread, sausage mixture, both cheeses and scallions. Gently mix together.
- Transfer to pan: Pour the bread mixture into the baking dish. Use a large wooden spoon to evenly distribute bread in dish.
- Add the egg custard: Pour the egg mixture evenly over the bread. Use a wooden spoon if necessary to push down the bread and filling to that it is mostly covered with the egg mixture.
- Chill: Cover the baking dish with plastic wrap and refrigerate. For best results, refrigerate at least 6 hours and up to 24 hours.
- Preheat the oven to 350 degrees F. Uncover the strata and brush the top with milk.
- Bake, uncovered, for 45 minutes. Remove the strata from the oven and break the burrata over the top of the strata, evenly distributing it. Return to the oven and bake an additional 15-20 minutes, or until the strata is just set and the cheese is bubbly.
- Serve: Remove from the oven and set aside to cool for 10 minutes before garnishing and serving. Enjoy!
Expert tips for the best egg casserole
- You can use any sausage: I used ground sweet Italian sausage, but you can use whatever type and flavor of sausage you prefer. If using sausage links, make sure you remove them from their casings before proceeding with the recipe.
- For the best taste, use an enriched bread: Bread is the star player in this casserole. I recommend you use a buttery, enriched bread such as challah, brioche or even (torn) croissants. If you can’t find any of those varieties, you can substitute any type of bread you would like. However, for the most luxurious mouthfeel I suggest trying to find a bread similar in taste, such as Parker House rolls, potato bread or even Hawaiian rolls.
- Don’t use fresh bread: Make sure your bread is stale and at least a day old! Fresh bread will completely disintegrate into the egg and milk mixture! However, if all you have is fresh bread, don’t worry! You can just toast the bread to get the same results as stale bread. Place the cubes of bread on a sheet pan and toast them in a 250 degree oven for 5-10 minutes, or until the cubes are just barely starting to crisp on the outside.
- Use cheese you love: If you aren’t crazy about burrata, you can either nix it completely from this breakfast casserole recipe or substitute whole milk ricotta, fresh mozzarella, or a mixture of both!

FAQs: breakfast egg sausage casserole
What sausage should I use in a breakfast casserole?
While ground breakfast sausage is traditionally used, you can use any variety of sausage you and your family prefer!
- Ground Breakfast Sausage: Also referred to as pork sausage or country sausage. There are different flavors of breakfast sausage, such as sage or maple. However, if you want to use breakfast sausage in this recipe, I would use either regular, all natural or country mild.
- Italian Sausage: Italian sausage is pork sausage flavored with fennel, garlic and other seasonings. Italian sausage is sold in links or in bulk (ground) and sweet, mild and hot varieties. You can use whatever variety you would like in this recipe. However, if you are using links you will need to remove the sausage from the casing before proceeding with the recipe.
- Chicken or Turkey Sausage: Chicken or turkey sausage is a wonderful healthier option!
- Chorizo: If you prefer a bit of heat, chorizo is a good choice.
- Ham: Not a fan of sausage? Feel free to use leftover, cooked ham instead!
- Bacon: Crispy, salty bacon is another delicious substitution!
What vegetables can I add to breakfast casseroles with eggs and sausage?
This casserole utilizes onions and red bell peppers. However, feel free to add any other vegetable you would normally include in a sausage omelet!
- Green Bell Peppers
- Scallions
- Mushrooms
- Olives
- Tomato
- Spinach
- Zucchini
- Yellow Squash
What fresh herbs pair well with breakfast egg and sausage casserole?
Herbs and seasonings are a great way to add even more flavor and customize this breakfast bake to your specific tastes!
You can use either fresh or dried herbs, however, fresh herbs will offer more flavor.
Fresh or Dried Herbs
- Basil
- Oregano
- Parsley
- Chives
- Thyme
Seasonings
- Onion Flakes
- Garlic Powder
- Fennel
- Paprika
- Red Pepper Flakes
Should I cover my breakfast casserole while it’s baking?
Whether or not a breakfast strata should be covered while baking depends entirely on the recipe.
This sausage egg casserole does not need to be covered while baking. However, if your oven runs hot and you find the top of the breakfast casserole browning before the casserole is set, you can lightly tent the top with foil while baking.
How long to do I bake a breakfast casserole egg and sausage?
You should cook this overnight breakfast egg sausage casserole long enough so that it is just set, as this is what keeps the inside fluffy. You don’t want the casserole to be runny, nor do you want it to be dry. I bake this breakfast casserole at 350 degrees Fahrenheit for 1 hour.
Note: Oven temperatures can vary greatly. If you think the casserole is done baking, you can test it to see if it’s cooked through. Insert a knife into the center of the casserole. If it comes out clean (with no uncooked egg), the casserole is done. Alternatively, a thermometer inserted into the center should read 160 degrees Fahrenheit.
Can you make it in advance?
Absolutely! As a matter of fact, sausage breakfast casserole is best when it is made ahead of time!
You can prepare this casserole up to 24 hours in advance and store it, covered, in the refrigerator. Preparing the casserole ahead of time and letting it rest in the refrigerator allows the custard to really work its magic and soak into the bread!
Serving this breakfast egg casserole with sausage
This easy pizza breakfast casserole is very filling and meant to be served as a complete meal since it contains carbs, protein, cheese and vegetables.
However, if you are looking to serve this sausage strata as a part of a breakfast spread, here are a few serving suggestions to round out this meal!
What to serve with a sausage breakfast casserole with bread
- Stand alone breakfast meats: bacon, sausage or Canadian ham
- Fresh fruit
- Fruit salad
- Yogurt
- Breakfast potatoes: hash browns, cubed breakfast potatoes, potato patties, roasted potatoes
Storing breakfast casseroles with sausage and eggs
How long will a baked egg casserole keep?
You can store any leftover sausage and egg breakfast in an airtight container in the refrigerator for up to 4 days.
Can you reheat sausage egg casserole?
The best way to reheat this egg and sausage breakfast casserole with bread is to use the microwave.
When you are ready to eat leftovers, slice an individual serving of casserole and place it on a microwave-safe plate and loosely cover. Microwave for 1 minute and then continue to microwave in 30-second intervals until warmed throughout.
Note: The size of the casserole portion and the power of your microwave will make the reheat time vary.
Can I freeze this bread egg sausage casserole?
Leftover cooked breakfast egg sausage casserole can be stored in an airtight container in the freezer for up to 2 months.
Alternatively, you can store unbaked sausage breakfast casserole in the freezer for up to 2 months. To freeze, assemble the casserole as directed. Instead of covering it and storing it in the refrigerator, wrap it with a layer of plastic wrap followed by a layer of aluminum foil. Store it in the freezer until ready to use. Make sure you allow the casserole to thaw in the refrigerator overnight before baking as directed.
Special enough for Christmas or New Year’s brunch, and too delicious NOT to make an appearance at any given Sunday brunch, this sausage and egg and cheese breakfast casserole is how you make your brunch game STRONG!
Until next week, friends, cheers. To making all your breakfast dreams come true!

Notes
- Sausage: I used ground sweet Italian sausage, but you can use whatever type or flavor of sausage you prefer. If using sausage links, make sure you remove them from their casings before proceeding with the recipe.
- Bread: You can substitute challah for the brioche bread. If you can’t find brioche or challah, you can substitute any type of bread you would like. However, for the most luxurious, rich mouthfeel I suggest a buttery bread similar to brioche or challah, such as potato bread or even Hawaiian rolls.
- Stale vs. Fresh Bread: Make sure your bread is stale and at least a day old! Fresh bread will completely disintegrate into the egg and milk mixture! However, if all you have is fresh bread, don’t worry! You can just toast the bread to get the same results as stale bread. Place the cubes of bread on a sheet pan and toast them in a 250 degree oven for 5-10 minutes, or until the cubes are just barely starting to crisp on the outside.
- Baking casserole: If the top of your breakfast strata starts to brown before the strata is set, you can lightly tent the strata with foil while baking. Just make sure to remove the foil from the strata and bake uncovered after you add the burrata cheese.
- Burrata substitute: If you aren’t crazy about burrata, you can either nix it completely from the recipe or substitute whole milk ricotta, fresh mozzarella, or a mixture of both!

Your mama’s monkey bread sounds amazing, but you know what? I’d take this strata any day! I love a good strata and this supreme pizza version (with BURRATA!) looks absolutely delicious. I could eat this for brunch or dinner any night of the week!
You had me at pizza flavor. We used to have a lot of Christmas traditions too, but I also live in a different state than my parents, so we wing it every year. I really like this recipe. I’d eat this any day of the week. I love the ingredients you used, but I also see opportunities to make all sorts of different pizza flavors! And your suggestion that Hawaiian bread might be good – I LOVE it. Hawaiian bread is my favorite.
Happy holidays!
I’m loving this love child of pizza + egg casserole! It’s definitely Christmas morning worthy and I don’t know, might be perfect paired with some monkey bread! Sounds like a great tradition to me!
