BREAKFAST CASSEROLE
I am so excited to bring you this sweet breakfast casserole recipe just in time for Easter! Because the holidays are a totally acceptable time to indulge in dessert for breakfast masquerading as a casserole. This breakfast bake is also fabulous for brunch, lunch, dinner and again for dessert!
I always have so many recipes I want to share for the holidays and never enough time to cram them in, but this croissant breakfast casserole shot to the top of the list because itโs irresistibly delicious and Iโm convinced it will become your most requested breakfast. Because really, whatโs better than a sweet breakfast casserole studded with berries that tastes like a Danish?!
Iโve seen croissant breakfast casseroles floating around Pinterest for some time, and although they look amazing, there are honestly some pretty big fails with soggy croissants and splitting custard โ but not this recipe! Iโve troubleshooted the issues to bring you the best breakfast casserole:
- First, you have to toast the croissants, otherwise, youโll end up with soggy, disintegrating breakfast casserole.
- Second, you have to use half and half, not milk, otherwise the custard wonโt be thick enough and you are destined for runny sogginess.
- Third, you have to layer the croissants and the custard in batches otherwise the custard isnโt evenly distributed.
- Fourth, itโs best to let the croissant breakfast casserole sit overnight so it can drink up all the flavor!
Now, all you have to do is follow the easy recipe, let it sit overnight in the refrigerator and bake it the next morning for a relaxed, stress free and delicious breakfast! With one bite, everyone in your household will be swooning over it!
INGREDIENTS FOR sweet breakfast CASSEROLE
The ingredients for this sweet breakfast casserole are easy to find at your grocery store. You will need:
- Croissants: Use large croissants from the bakery section of your grocery store, not the ones in the tube. Youโll need about 10 packed cups, but there is some wiggle room.
- Berries: Use your favs! I prefer raspberries, blueberries and blackberries in this recipe but you can also add strawberries.
- Eggs: Use large eggs at room temperature. This will help them mix more easily with the cream cheese.
- Half and half: Pease use half and half and not milk otherwise your croissant breakfast casserole may be runny. You may use half heavy cream and half milk to make your own half and half.
- Granulated sugar: Sweetens the cream cheese and allows the lemon flavor to shine.
- Lemon juice and lemon zest: Brightens the custard with a subtle fresh pop of citrus; please donโt skip or the custard tastes flat.
- Vanilla extract: Use quality extract for the best flavor.
HOW TO MAKE THIS SWEET BREAKFAST CASSEROLE
- Toast croissants. Add the cubed croissants in a single layer to a large baking sheet and bake until toasted, about 7-10 minutes.
- Make cream cheese custard. Beat cream cheese, sugar, eggs, half and half, lemon juice, lemon zest and vanilla extract in a mixing bowl with a hand mixer until smooth.
- Assemble casserole. Layer a lightly greased 9×13 baking dish with croissants, berries, half of the custard and then repeat.
- Refrigerate overnight. Cover the sweet breakfast casserole tightly with foil and refrigerate overnight so the croissants can drink up the custard.
- Bake. The next relaxed, stress free morning, bake for 45 minutes or until the custard is set.
- Lemon drizzle. While the casserole is baking, make the Lemon Glaze by beating cream cheese, powdered sugar, lemon juice and vanilla extracting in a mixing bowl. Drizzle it all over the croissant breakfast casserole and dig in while itโs warm!
COOKING TIPS FOR THIS BREAKFAST Casserole
- Prepare your baking dish: Donโt forget to lightly grease your 9ร13-inch baking dish with nonstick cooking spray otherwise your croissant breakfast casserole will stick!
- Use quality croissants: This isnโt the time for pop and bake croissants. You want medium to large croissants from the bakery section of the grocery store because they have more fabulous flaky layers for the custard to hide in.
- Toast croissants: Toasting the croissants gives them structure so they have the capacity to soak up the custard without becoming soggy โ donโt skip this step!
- Donโt burn croissants: There are severable variables when toasting the croissants such as the freshness of the croissants, so keep an eye on them so they donโt burn!
- Cool the croissants: Give the croissants some time to cool before drenching in the custard so they can firm up a bit โ otherwise this defeats the purpose of toasting them!
- Use room temperature ingredients: Youโll want to use room temperature cream cheese, eggs and half and half, otherwise the cream cheese will seize and not mix well. If you do end up with some white flecks of cream cheese, itโs okay, it will melt when the breakfast casserole bakes.
- Use soft cream cheese: To that end, make sure you cream cheese is very soft. This is one time itโs okay to gently microwave your cream cheese, just make sure not to scorch it!
- Use fresh or frozen berries: Fresh is best but frozen mixed berries will also work -no need to thaw first.
- Submerge the croissants in the custard. After youโve added the last of the custard to the casserole but before you top with the remaining berries, press the croissants down gently with your hands so that most of the croissants are submerged in the custard. The very tops will likely be sticking up which is okay.
- Add powdered sugar to taste: The powdered sugar dusting is honestly more for aesthetic reasons. I recommend serving the sweet breakfast casserole without the powdered sugar and then letting individuals decide if they would like their serving sweeter.
WHAT WENT WRONG IF MY sweet breakfast CASSEROLE IS SOGGY?
You should expect your breakfast croissant casserole to be soft, but not mushy. If itโs soggy, there could be a few culprits:
- Problem: You did not use enough croissants.
- Answer: You need 10 packed cups of croissants for the proper bread to custard ratio.
- Problem: The croissants were too soft to absorb the egg custard
- Answer: Make sure the croissants are STALE like croutons by toasting the cubes in the oven and then waiting for them to cool and firm up.
- Problem: The custard was runny.
Answer: Donโt use milk; only half and half. Before you pop the sweet breakfast casserole in the oven, inspect to see if most of the custard is absorbed, if not, pour off all but about half a cup or so.
- Problem: The casserole sat too long.
- Answer: Donโt prep the breakfast bake too far in advance. Prep the casserole in the evening and bake it the next morning.
VARIATIONS OF THIS overnight breakfast casserole
- Other breads: This breakfast bake will also work with French bread to create a French toast casserole. Purchase the French bread, cut it into cubes and let it dry out for a couple days on the counter or toast the cubes like you do the croissants until crispy like croutons.
- Other flavors: This recipe is bright and lemony for spring, but are welcome to mix up the flavor profile. You can omit the lemon and go more maple/cinnamon by swapping half of the sugar in the custard and in the glaze with pure maple syrup and adding additional cinnamon. Alternatively, you can omit the lemon in the glaze and go for straight vanilla. You can also swap the lemon for orange juice and orange extract and add a splash of almond extract.
- Omit the glaze: The lemon glaze is fabulous and a recipe highlight in my opinion, but you can omit it and sprinkle the casserole with powdered sugar and serve with maple syrup instead.
- Add a streusel: I love adding streusels to my overnight breakfast casseroles for a contrasting crunch. If you want to add a streusel, follow the instructions for this recipe.
HOW DO I MAKE GLUTEN-FREE sweet breakfast CASSEROLE?
You will probably have trouble locating gluten free croissants so the next best bet is to use your favorite thick gluten-free bread. Make sure to toast the bread like you do the croissants so they resemble croutons.
WHAT TO SERVE WITH this Breakfast BAKE
This breakfast bake has the fruit and sweet breakfast portion covered, and Iโm honestly good with that, but if you are looking to flush out the meal, here are some savory options:
- Protein: bacon, breakfast sausage, ham (leftover Easter ham is perfect!), etc.
- Eggs: scrambled, fried, over-easy, hard-boiled, soft-boiled, poached, deviled, or as eggs benedict, an omelette or baked egg muffins.
- Skillets: bacon and egg hash, corned beef hash, frittata, chilaquiles, etc.
- Bakes: quiche, sausage breakfast casserole, eggs benedict casserole, ham and cheese breakfast enchiladas
MAKING BREAKFAST CASSEROLE AHEAD OF TIME
I usually dedicate an entire section on how to prep a recipe ahead of time, but the beauty of this overnight breakfast casserole is it meant to be prepped almost 100% ahead of time! Besides the casserole itself, the only item left to make is the lemon glaze. This can also be made ahead of time and stored in the refrigerator.
The glaze will thicken upon refrigeration so you will need to let it come to room temperature before serving and may even need to whisk in a couple tablespoon of half and half to thin it again. Taste the glaze before serving, as the lemon will mellow upon refrigeration, then adjust if needed.
CAN YOU MAKE breakfast CASSEROLE WITHOUT SITTING OVERNIGHT?
There is a reason this is an overnight breakfast casserole โ it gives the custard time to permeate and really soak into the croissant crevices. This results in sublime flavor and texture through and through. So, for best results, plan on OVERNIGHT breakfast casserole preparation. You can still make this recipe without letting it rest overnight, but adjust your expectations as the casserole wonโt be as fluffy and may be runnier as the custard wonโt have as much time to soak in.
To make and bake this breakfast casserole immediately, skip toasting the croissants and instead let the casserole sit on the counter for 30-60 minutes so the croissants can soak up the liquid then bake per recipe instructions.
HOW LONG IS ThiS Breakfast BAKE GOOD FOR?
This breakfast bake should be tightly covered or stored in an aright container in the refrigerator for up to 4 days.
HOW TO REHEAT breakfast CASSEROLE
You can reheat leftover sweet breakfast casserole two ways:
- Microwave: The microwave is good for instant pleasure and individual pieces but you will lose some of the structural integrity of the breakfast bake. To microwave, add individual slices to a microwave safe plate and microwave for one minute. Continue to microwave at 30 second intervals if needed to heat through.
- Oven. Reheating leftover breakfast croissant casserole in the oven will yield the best results. Cover casserole with foil and bake at 325 degrees F for 20 minutes or until warmed through.
HOW TO FREEZE sweet breakfast CASSEROLE
You can freeze the breakfast croissant casserole before or after baking, but for best results, freeze before baking.
TO FREEZE BEFORE BAKING:
- Completely assemble your breakfast bake in a freezer safe 9×13 dish but donโt bake.
- Tightly wrap casserole in plastic wrap a couple times followed by foil.
- Freeze for up to 2 months.
- When ready to cook, thaw casserole in the refrigerator overnight.
- Bake the next morning per recipe instructions, being prepared to add an additional 5-10 minutes.
TO FREEZE AFTER BAKING:
- Allow casserole to cool completely.
- Tightly wrap casserole in plastic wrap a couple times followed by foil.
- Freeze for up to 2 months
- When ready to cook, thaw casserole in the refrigerator overnight.
- Reheat in the oven at 325 degrees F for 20 minutes or until warmed through.

Ingredients
Casserole
- 8 large croissants (from the bakery) sliced into 1-inch cubes (10 packed cups)
- 4 cups mixed berries (I use raspberries, blackberries, blueberries)
Custard
- 14 ounces cream cheese, softened
- 1 1/4 cup granulated sugar
- 6 eggs at room temperature
- 2 cups half and half at room temperature
- 1 tablespoon vanilla extract

- 2 teaspoons lemon zest
- 1/4 teaspoon salt
Cream Cheese Lemon Glaze
- 2 ounces cream cheese, softened

Instructions
- Toast croissants: Preheat oven to 350 degrees F. Add the cubed croissants in a single layer to a large baking sheet (15×21-inches). Bake 350 degrees F for 7-10 minutes until golden and very toasted (keep an eye on them so they donโt burn!). Set aside to cool.
- Custard: Add cream cheese and sugar to a large mixing bowl and beat with a hand mixer until smooth. Beat in the eggs until smooth, followed by the half and half, and finally the lemon juice, lemon zest, vanilla extract and salt.
- Assemble: Transfer half of the croissants to a lightly greased 9×13 baking dish, then evenly layer with half of the berries. Pour half of the custard evenly over the dish. Add remaining croissants in a single layer followed by remaining custard. Press down with your hands so most of the croissants are submerged in the custard (itโs okay if the tops aren't). Scatter remaining berries over the dish. Cover with foil and refrigerate overnight.
- Bake: When ready to bake, remove the casserole from the refrigerator and let it sit on the counter while you preheat the oven to 350 F degrees. Bake, covered with foil, for 30 minutes. Remove the foil and bake, uncovered, for an additional 15 minutes, or until a knife inserted in the center comes out clean.
- Lemon Glaze: While the casserole is baking, make the Lemon Glaze. Add all of the Glaze ingredients to a medium mixing bowl and beat with a hand mixer until smooth. Taste and add additional sugar for sweeter or lemon juice for tangier. Drizzle the glaze all over the casserole.
- Serve: Serve the breakfast casserole warm. Let individuals dust their servings with powdered sugar if they would like it sweeter.

Becca says
Iโve made this recipe once before but the baking for me took quite a bit longer than the recipe states. I decided to try again and am having the same results, checking with a knife which does not come out clean. Iโve already baked it 15 minutes longer than the recipe suggested and it is still not done which was my problem last time. Not sure what Iโm doing wrong that my time is differing so much, but my husband and I love the flavor and are looking forward to trying a different fruit mix this time around.
Jen says
I am not sure why the time is differing, but I am so glad that you and your husband loved the flavor!
kathleen says
check your oven — i was having problems with things getting done properly and when i got a little oven thermometer i found that my oven temps are off. now i use the temp on the thermometer instead of the oven dial and it has made a big difference.
Carola says
I have had this dish 2 times when a friend made it for us. I am thinking this would be a great dessert for my guests Thursday. Would it be ok to get it ready in the morning and then bake it in the evening?
Jen says
Yes, that should work perfectly! I hope you and your guests love it!
Tracy Dalykas says
I did make this recipe but I tweaked it to our tastes. I substituted orange zest and juice for the lemon. I also used plain clearance croissants and 1 pack of petite chocolate croissants I found at walmart that were perfect. I also used a frozen berry mix from walmart that had blueberries, blackberries and raspberries. I did not have enough cream cheese but used marscapone as well as adding almond extract and I cut the sugar to suit our taste by 1/4 cup. It was amazing. I will definitely make this again. The chocolate and orange were a nice subtle flavor that complimented each other with the berries I used.
Jen says
Yum! I’m so glad that it will be a repeat!
Laura says
I made this exactly as stated in the recipe for Christmas morning and it was a HUGE hit! Everyone loved it! Make sure you plan ahead so that the ingredients can be at room temp and so that it can sit overnight. I am curious how it would taste with peaches or other fruits. I used blackberries, blueberries, and raspberries.
Jen says
Yum! I’m so glad that it was a winner! Thank you for trying out the recipe and sharing your experience!
India says
Was delicious but took wayyy longer to cook than stated-took about an hour and a half…so served after breakfast was done which was a bummer but it was delicious none the less.
Jen says
I’m sorry India! Every oven cooks differently and there are a variety of factors when baking.
kathleen says
loved this! made it this morning for our Easter breakfast and it was SOOOO good. it was also nice to be able to put it together last night and just bake this morning. This will make a great dessert as well – and since it is basically a bread pudding made with croissants i want to try it with a yummy whiskey sauce on it.
Jen says
I’m so glad it was a delicious part of your holiday! Hope your dessert version is great as well!
Marcia says
Is the temp too low on the croissant egg bake? I baked as instructed, 40 min covered, 15 (or more) uncovered.
My knife is wet when I test. I baked 30 minutes additional after initial instructions, and it is still WET! (Trying to not have top totally burn so I set foil on top when I did the additional 20 min. Foil was not secured around casserole pan.)
Just more time, or should it have been at higher oven temp.
Jen says
I’m sorry it took longer than expected! Perhaps you used a glass dish? Glass takes longer to heat up, but then retains heat well which can brown the edges quickly. A reader shared the tip of lowering the baking temperature 25 degrees and baking for longer. Hope this helps!
Destiny Schermerhorn says
Can i use frozen fruit?
Jen says
Yes, frozen works great! There’s no need to thaw first. Hope you enjoy!
Julie says
This was excellent! Wondering if you have ever made it savory? Spinach? Leeks? Mushrooms? Gruyรจre? Thoughts?
Jen says
Thanks I’m so glad you enjoyed it! Not yet, but that sounds like a delicious experiment!
