No worries if you don’t have breakfast sausage—I often use chopped ham or cooked bacon in my Croissant Breakfast Casserole with great results. You can even swap cheddar for mozzarella or Swiss cheese without missing a beat.

You’ll find these ingredients in the regular grocery aisles, making this savory croissant bake easy to shop for without a special trip.

Budget-friendly note: This Croissant Breakfast Casserole keeps costs reasonable because croissants don’t need to be fancy. Day-old or on-sale croissants work perfectly here, helping you stretch the grocery budget while delivering rich flavor.

Prep shortcut: I like to cook the sausage and shred the cheese ahead of time, which speeds things up when you’re ready to assemble. And if you have leftovers, this croissant egg bake stores beautifully in an airtight container in the fridge for up to 4 days.

A little tip: I like adding a bit more cheese on top before baking—you get that beautiful golden crust that everyone loves. Feel free to add your favorite veggies or swap out the herbs to suit your family’s tastes.

Can I make this Croissant Breakfast Casserole ahead of time?
Absolutely. It works great as an overnight breakfast casserole. Prepare the casserole but don’t bake it. Cover and refrigerate overnight. In the morning, bake it from cold, adding about 10 extra minutes. This lets the croissants soak up the custard perfectly.

What if I don’t have croissants on hand?
You can try using cubed brioche or even a sturdy white bread as a substitute. But croissants bring that buttery richness you don’t get with everyday bread, so try to grab croissants when you can.

Can I freeze leftovers?
Yes! Portion out the Croissant Breakfast Casserole in airtight containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating in the oven.

What’s a good vegetarian version?
Swap the sausage for sautéed mushrooms, bell peppers, and spinach. Add extra cheese or a sprinkle of parmesan on top for flavor depth. This way, you get a tasty croissant egg bake without meat.

How do I adjust this recipe for more or fewer people?
The ingredients scale nicely. For fewer servings, halve the recipe and use an 8×8 dish. For larger groups, double and use a larger casserole pan. This recipe is flexible.

Can I add other ingredients like vegetables?
Definitely. Bell peppers, spinach, tomatoes, or mushrooms all work well in this croissant breakfast casserole. Just make sure any veggies are cooked or sautéed first to prevent too much moisture.

Why does my Croissant Breakfast Casserole sometimes come out soggy?
That usually means the custard soaked too long or the oven temperature was too low. Make sure your eggs and milk ratio is right and bake until the top is golden and the center just sets. Don’t skip the resting time either.
