Breakfast Casserole Recipes: 15+ Reader-Tested Favorites for Every Morning
A breakfast casserole is the one dish that checks every single box — it feeds a crowd, it can be made the night before, and there is almost always a version that works for whatever ingredients you have on hand. I have been making and testing breakfast casseroles on Salty Side Dish since 2017, and the collection below is the result of years of reader feedback, holiday mornings, and a lot of delicious testing.
Whether you are looking for a classic sausage and potato bake, something loaded with bacon and cheese, a sweet French toast casserole for a brunch crowd, or a veggie option — it is all here. Every recipe on this page has been made in my kitchen, tested more than once, and reviewed by real readers who made them for their own families.

Hashbrown Breakfast Casseroles
Hashbrown casseroles are the backbone of breakfast for a crowd. Shredded frozen hashbrowns make the perfect base because they soak up the egg and cream mixture as the casserole bakes, creating a dense, satisfying layer that holds every slice together cleanly. You can use shredded hashbrowns for a softer texture or tater tots for a bit more structure and crunch — both work in most of the recipes below and are easy to swap. These are the dishes people make on Christmas morning, Easter, and any holiday where you need one pan to feed 10-12 people without standing at the stove.

Sausage Breakfast Casseroles
Sausage is the protein that makes a breakfast casserole feel like a real meal. It adds richness, seasoning, and that savory depth that keeps everyone full well past lunch. The recipes in this section range from the classic sausage and hashbrown bake — our most popular breakfast casserole recipe on the entire site — to a Southern grits casserole and a loaded biscuits and gravy version that is genuinely over the top in the best way. All three can be prepped ahead, and all three feed a generous crowd.
Here are three ways to put sausage front and center for breakfast:
restaurant-quality
Breakfast Strata
A strata is what happens when a breakfast casserole and a savory bread pudding have a very delicious baby. Instead of a potato base, stratas are built on layers of bread — usually something sturdy like Italian or sourdough — soaked in a rich egg custard and baked until the outside is golden and the inside is soft and custardy. They feel restaurant-quality on the table but come together with basic ingredients. Our Ham and Cheese Strata is the reader favorite in this category and is an excellent make-ahead option for brunch.
Sweet Breakfast Casseroles
Not every breakfast casserole has to be savory. Sweet casseroles built on thick-cut bread, cinnamon, fruit, and a custard egg base are the kind of dish that makes people think you worked much harder than you did. They are perfect alongside a savory casserole at a big holiday brunch, or completely on their own when you want something that feels a little indulgent. Most of these can be assembled the night before and go straight from the fridge into a preheated oven — a total win on busy mornings.
Easy Egg Breakfast Casseroles
These are the egg-forward casseroles — dishes where the egg mixture is the star, not just the binder. From the fully loaded Ultimate Sunday Breakfast Casserole packed with biscuits, gravy, and hashbrowns to the uniquely cheesy Amish Breakfast Casserole that uses cottage cheese for a dense, incredibly satisfying texture, these are the recipes that feel like a full breakfast in every single bite. Great for Sunday mornings, holiday brunches, and potlucks where you need something that looks impressive and tastes even better.

Vegetable Breakfast Casseroles
Meat-free does not mean flavor-free. A good vegetable breakfast casserole is packed with color, texture, and enough protein from eggs and cheese to keep everyone satisfied. These are great for feeding a mixed crowd — guests who do not eat meat, lighter eaters, or anyone who just wants something a little fresher on the plate. Our Spinach Mushroom Egg Casserole is the standout here and works beautifully as part of a larger brunch spread alongside one of the sausage or hashbrown dishes above.
No Meat here!
Healthy Egg Bake
Our choice for a full veggie casserole recipe, Spinach Mushroom Egg Casserole, is a great veggie only dish. But in most cases, can also add tomatoes, diced onions, colored bell peppers, or sliced green onions as a topping to egg- or potato-based casseroles as well.
How to Make a Perfect Breakfast Casserole Every Time
A few things make the difference between a good breakfast casserole and a great one. Here is what I have learned after years of testing:
- Thaw your hashbrowns the night before. Frozen hashbrowns release water as they cook. If you put them in frozen, that water has nowhere to go and you end up with a watery, soggy casserole bottom. Pull them from the freezer the night before, let them thaw in the fridge, and drain off any extra liquid before layering them in the pan. This single step makes a huge difference.
- Use heavy cream, not milk. Milk works in a pinch but heavy cream gives you a rich, custardy egg layer that is noticeably better. It also helps the casserole hold together when you slice it. If you must substitute, half and half is the next best option.
- Cover with foil for most of the bake. Covering the dish prevents the edges from overcooking before the center sets. For most casseroles, bake covered for the majority of the time, then remove the foil for the last 15-20 minutes to get a golden, slightly crispy top layer.
- Don’t skip the rest time. Pull the casserole from the oven and let it sit for at least 5-10 minutes before cutting. The egg mixture continues to set as it cools slightly, and you will get cleaner slices that hold their shape on the plate.
- Assemble the night before for stress-free mornings. Almost every savory casserole on this page can be fully assembled, covered tightly in foil, and refrigerated overnight. In the morning, pull it out while the oven preheats, then bake as directed — sometimes adding a few extra minutes since it is starting cold. Holiday mornings are so much easier this way.
- Season the egg mixture well. Eggs need salt, and they can handle more seasoning than you think. Garlic powder, black pepper, and a good amount of salt in the egg and cream mixture is what separates a bland casserole from one that tastes complete.
Breakfast Casserole Questions — Answered
Can you make breakfast casserole the night before?
Yes, and for most savory casseroles this is actually the recommended method. Assemble everything in your baking dish, cover tightly with foil or plastic wrap, and refrigerate overnight. In the morning, pull it out while the oven preheats to take the chill off slightly, then bake as directed. If it is going in straight from the fridge, add about 10 extra minutes to the bake time and check the center before pulling it out.
What is the best potato to use in a breakfast casserole?
Shredded frozen hashbrowns are the classic choice and give you a soft, cohesive layer that blends into the casserole. Tater tots give you more structure and a denser bite with slightly more texture since the outside is already cooked. Diced potatoes work too but take longer to get tender. The most important thing with any frozen potato is to thaw and drain them first — frozen potatoes release water as they cook and can make your casserole soggy.
Can you freeze breakfast casserole?
Most savory breakfast casseroles freeze well, either baked or unbaked. Freezing before baking gives you the best texture results — assemble the casserole, wrap the dish tightly in plastic wrap and then foil, and freeze for up to 2 months. Thaw overnight in the refrigerator before baking. If freezing leftovers that are already baked, store in individual portions and reheat in the oven at 350 covered with foil until warmed through. Sweet casseroles like French toast bakes can get a little soft after freezing but still taste good reheated.
What cheese works best in breakfast casserole?
Sharp cheddar is the go-to because it melts well and has enough flavor to stand up against eggs, sausage, and potatoes. For a little heat, Pepper Jack is a great swap. Colby Jack gives you a milder, creamier melt. Monterey Jack works well in casseroles where you want the cheese to blend rather than be the star. The Amish Breakfast Casserole on this page uses cottage cheese as part of the base layer — it sounds unexpected but it creates the most incredibly dense, cheesy texture and is one of our most popular recipes for a reason.
How do you know when a breakfast casserole is done baking?
Insert a butter knife into the center of the casserole and pull it gently to one side. If you see runny or pooling egg mixture, it needs more time. If it comes out with nothing liquid clinging to it, the casserole is set and ready. The center should look firm but not dried out or cracked. Ovens vary, so start checking about 5 minutes before the recipe states and go from there.
How long does breakfast casserole keep in the refrigerator?
Because of the eggs, dairy, and meat involved, I do not recommend keeping leftovers for more than 3-4 days in the fridge, stored tightly covered. Reheat individual portions in the microwave in 60-second intervals until hot throughout, or rewarm the full dish covered in foil in a 350-degree oven. If you want to keep it longer than that, freeze it instead.
What is the most popular breakfast casserole?
On Salty Side Dish, it is the Sausage Hashbrown Breakfast Casserole — by a wide margin. It has close to 1,800 five-star reviews from readers who have made it for Christmas morning, Easter brunch, church potlucks, and regular Sunday breakfasts. It is simple, feeds 12, and uses ingredients that are almost always already in the fridge and freezer. If you have never made a breakfast casserole before, that is the one to start with.
Breakfast casseroles are one of those recipes that genuinely never get old. The combinations change with the seasons — a loaded cowboy casserole in the fall, a blueberry French toast bake in the summer, a classic sausage hashbrown bake every Christmas morning without fail — and there is always a version that fits the occasion.
Bookmark this page and come back to it. People do — I see it in the traffic every November when holiday planning kicks in, every spring before Easter, and every time someone discovers they need to feed 12 people with one pan and zero stress. The collection will keep growing as new recipes get tested and approved.
