28 Easy Make-Ahead Breakfast Casserole Recipes

Breakfast Casserole
A savory mix of eggs and sausage gets tossed with cubed bread in a trusty 13×9 pan. Left in the fridge overnight, the bread absorbs some of the liquid, becoming almost melty and custardy. It needs to bake only 40 minutes in the morning, and breakfast is served.
Amish Breakfast Casserole
One of our best breakfast recipes just so happens to be a make-ahead breakfast casserole. There’s a hash brown base under all the cheese, bacon and eggs!
Garden Veggie Egg Bake
Our garden veggie bake is beautiful, bold, and filled with vegetables and protein-rich dairy. Try the vegetable blend in our recipe or make this egg bake as an excuse to use whatever vegetables are plentiful in your garden or on their last leg in your fridge.
Hash Brown Breakfast Casserole
This hash brown egg casserole is an all-in-one dish. Hash browns, eggs, bacon and cheese meet breakfast demands. Serve each slice with some fruit for a refreshing palate cleanser.
French Toast Casserole
While French toast is a breakfast staple, standing over the stove all morning, soaking and flipping individual slices of bread for a large crowd, isn’t exactly ideal. Instead, French toast casserole makes things 10x easier. The bread soaks overnight and everything bakes in the oven the next morning, so guests are served plates of hot French toast all at once.
Sausage & Crescent Roll Breakfast Casserole
At this point, I’m convinced there’s nothing a tube of crescent rolls can’t do. Here, it forms the crust of an incredible sausage and egg casserole. It’s sort of like a super easy quiche or a breakfast-style pizza. Either way, we’re sold!
Tater Tot Breakfast Casserole
Say “Tater Tots” and the kids come running. What’s more, Canadian bacon, onions, cheese and eggs fill out the casserole in between the puffs of tots, and a bunch of familiar seasonings tie everything together.
Biscuits and Gravy Casserole
As if a make-ahead casserole recipe wasn’t easy enough, a box of biscuit mix makes this biscuit and gravy casserole feel truly effortless. Take it one step further and break out a tube of store-bought biscuits.
Croissant Breakfast Casserole
Baked with croissants (store-bought are fine!), Gruyere, Dijon, eggs and sausages, this is a French-inspired breakfast casserole that guests will adore. For a make-ahead version, use stale croissants, which retain more of their integrity than soft, freshly baked croissants.
Eggs Benedict Casserole
Admittedly, I would never make eggs Benedict for a crowd. Between poaching eggs, emulsifying hollandaise and building the Benedicts, there are too many variables for mishap. However, this eggs Benedict casserole solves every problem. All the components bake together, then an easy hollandaise is poured on top.
Pancake Casserole
Sausages and pancakes may sound like an odd pairing to you, but this sweet and savory combo goes well together. The secret? Tie them together with the condiment they both pair best with: maple syrup!

What makes this sausage and hash brown casserole better than the rest? It’s exceptionally rich thanks to cream of chicken soup, sour cream and French onion dip.

Bananas Foster French Toast
Could anyone turn down sweet breakfast ideas as decadent as bananas Foster French toast? This overnight recipe lets the challah soak in the custard all night and bakes the next morning, so the banana topping caramelizes beautifully.

Between a frenzy of wrapping paper flying everywhere to excited gasps with show and tells to follow, Christmas morning is hectic. Take one task off your plate that morning and assemble this special Christmas breakfast casserole the night before—right before Santa comes. Pop it in the oven the next morning before everyone opens gifts.
Southwest Sausage Bake
Tortillas are the totally unexpected (or completely expected?) carb in our Southwest sausage bake. Assemble the casserole the night before so the tortillas can soak and soften into the eggs.

This farmer’s casserole is a contest winner for a reason. Everything is assembled the night before so the flavors from the hash browns, cheese, ham, eggs and milk can meld. Serve this simple breakfast with a batch of muffins or a gorgeous fruit salad.

A classic Reuben sandwich is the inspiration behind this brunch bake. Expect this casserole to have everything you love about a Reuben, from the rye bread to the sauerkraut, Swiss cheese and corned beef. The recipe is perfect for anyone looking for breakfast ideas without eggs!
French Toast Casserole with Cream Cheese
Between its flavor and ease, baked French toast is hard to beat. But this recipe is slightly better than the rest thanks to big hunks of cream cheese baked right in. I recommend adding berries, nuts or streusel on top.
Overnight Asparagus Strata
I love the idea of this strata as a way to use up leftover Easter ham, which is usually available right around the time asparagus is in season. Crusty English muffins bulk out the casserole. Colby-Monterey Jack and lots of milk make it super creamy.
Pumpkin French Toast Casserole
Cinnamon-raisin bread and a pumpkin-cream cheese custard soak overnight and bake into the most dreamy fall breakfast ever. I can’t think of a better accompaniment than a homemade pumpkin spice latte.
Blueberry French Toast Casserole
The finishing touch that takes this blueberry-cream cheese French toast bake over the top? The included homemade blueberry sauce, and add some quality maple syrup to boot.

A classic strata (an Italian bread-and-egg casserole) is jazzed up with an array of delicious fillings (totally customizable, of course). It’s hearty, filling and contains half the amount of eggs found in the usual breakfast casserole.
Greek Breakfast Casserole
In this Greek breakfast casserole, you’ll find hunks of feta, artichoke hearts, broccoli, sun-dried tomatoes, shallots and herbaceous seasonings suspended in delicately baked eggs.
Vegetable Strata
This vegetarian-friendly strata is loaded with all kinds of fresh veggies, a mound of Italian bread, a few eggs and Alpine-style cheese. Pecans are unexpected but add nice a crunch among the soft texture.
Green Chile Brunch Bake
What I love about this casserole is that, yes, it can bake in a 13×9-inch pan. But you could also make individual servings by baking it in a muffin tin. This is best for a buffet-style brunch where everyone is loading their plate with all sorts of servings from different brunch recipes.
Baked French Toast
Once this baked French toast emerges from the oven, top it with whatever fruit is in season. While citrus fruits are plentiful in winter, they wouldn’t pair here, so go with a banana and Nutella topping.
Make-Ahead Breakfast Casserole Recipes FAQs
Can you refrigerate a casserole before baking?
Yes, you can refrigerate most casseroles before baking. Simply assemble the casserole in the dish, then cover it tightly with storage wrap or aluminum foil. When you’re ready to bake it, take the casserole out of the fridge and let it sit at room temperature for 30 minutes. Putting a cold dish into a hot oven is not a good idea, as the dish can crack. During the last 10 minutes, preheat the oven.
How long can a breakfast casserole sit in the fridge before baking?
A well-covered breakfast casserole can sit in the fridge for eight hours before baking. Raw eggs are very perishable, so it’s best not to let them hang out uncooked for too long. Also, if there is bread in the casserole, you don’t want it to sit for too long or it may become soggy.
Why is my breakfast casserole soggy?
Your breakfast casserole might be soggy for a few reasons. The most common is if you used frozen ingredients. Frozen ingredients expel a lot of excess water during baking, so it’s best to thaw and drain them before use. Also, prepare any vegetables in the dish ahead of time. Vegetables hold on to a lot of water and should be cooked before going into the casserole to help draw out some of the water. Lastly, take the lid or wrapping off the casserole for the last 10 minutes of baking so excess liquid can evaporate and create a crunchy topping.
