School is starting, which means our mornings are about to get chaotic again. And mornings are chaotic enough—breakfast doesn’t have to be.
We literally have no time in the morning before school for me to make breakfast from scratch. Between getting everyone dressed, finding shoes, packing bags, and actually getting out the door on time, I need breakfast to be as easy as possible. That’s why I love breakfasts I can prep ahead of time, keep in the freezer, and pull out when we need them.
These baked croissant egg sandwiches are perfect for exactly that. Buttery croissants are layered with turkey, cheese, and eggs and baked together in one pan. They freeze beautifully, reheat well, and make busy school mornings just a little easier.
Easy Breakfast for Busy School Mornings
I love a breakfast I can make once and have ready for later.
Instead of standing in the kitchen making individual breakfast sandwiches in the morning, these baked croissant egg sandwiches let you prepare an entire batch at the same time.
The croissants are layered with melty cheese and turkey, then topped with eggs and baked until everything is hot and the eggs are set.
You can serve them immediately, but they’re also great for meal prep. Once they’re completely cool, I like to freeze the sandwiches individually. Then, on busy mornings, I can pull out exactly what we need and reheat them.
The air fryer or toaster oven works especially well because it heats the sandwich while bringing back that buttery, slightly crisp croissant texture.
Why You’ll Love These Baked Croissant Egg Sandwiches
These are especially great during back-to-school season because you can make several breakfasts at once instead of starting from scratch every morning.
They’re:
- Easy to assemble in one baking dish
- Kid-friendly
- Great for breakfast meal prep
- Freezer-friendly
- Easy to customize
- Perfect for busy weekday mornings
- Easy to reheat in the air fryer or toaster oven
- A simple way to make breakfast for the whole family
And because they’re individual sandwiches, you can freeze them separately and take out only as many as you need.
Ingredients for Baked Croissant Egg Sandwiches
You’ll need:
- 5 croissants
- 6 eggs
- 5 sliced turkey
- Sliced cheese
- 1/2 cup Milk
- Salt, to taste
- Black pepper, to taste
- Nonstick cooking spray or butter, for greasing the baking dish
Easy Substitutions
One of the best things about these croissant breakfast sandwiches is how easy they are to customize.
You can use cheddar, mozzarella, Swiss, Gouda, or another cheese that melts well. You can also swap the turkey for another cooked breakfast protein your family likes.
For a meatless version, simply leave out the turkey and make baked egg and cheese croissant sandwiches instead.
How to Make Baked Croissant Egg Sandwiches
1. Prepare the Baking Dish
Preheat the oven to 200°C / 400°F.
Lightly grease the bottom of a baking dish with nonstick cooking spray or butter. This helps prevent the eggs and croissants from sticking to the bottom as they bake.
2. Arrange the Croissants
Slice each croissant horizontally through the middle.
Arrange the five bottom halves in the prepared baking dish.
3. Add the Cheese and Turkey
Layer the cheese over each croissant, followed by the sliced turkey.
4. Pour Over the Eggs
Crack the eggs into a bowl and season with salt and black pepper. Add [MILK/CREAM/OTHER INGREDIENTS, IF USED] and whisk until well combined.
Slowly pour the egg mixture evenly over the layered croissants.
5. Add the Croissant Tops
Place the top half of each croissant back over the filling.
6. Bake
Bake the croissant egg sandwiches uncovered at 200°C / 400°F for 20–25 minutes, or until the eggs are completely set and cooked through in the center.
If the croissant tops are getting too brown before the eggs are finished cooking, loosely tent the tops with foil toward the end of the baking time.
How to Make These Ahead of Time
These baked croissant egg sandwiches are perfect for meal prep, especially when school starts and mornings suddenly become much busier.
Bake the sandwiches according to the recipe and allow them to cool completely before storing.
You can keep them in the refrigerator if you’ll be eating them within the next few days, or freeze them individually for an easy breakfast you can grab whenever you need one.
How to Freeze Croissant Breakfast Sandwiches
Let the baked sandwiches cool completely before freezing. This is important because wrapping them while they’re still warm can trap steam and make the croissants soggy.
Once cool, separate the sandwiches and wrap them individually or place them in individual freezer-safe containers or bags.
Freeze until you’re ready to eat them.
I prefer freezing them separately because I can grab exactly what we need on a school morning without having to defrost the entire batch.
How to Reheat Frozen Croissant Egg Sandwiches
My favorite ways to reheat these sandwiches are the air fryer or toaster oven.
Both methods warm the egg, turkey, and cheese while helping the outside of the croissant crisp back up.
Reheat the sandwiches from frozen until the center is completely heated through.
Because air fryers and toaster ovens vary, check your sandwich as it reheats rather than relying on one exact time. If the outside is browning before the center is hot, lower the temperature and continue heating until warmed through.
Pro Tips for the Best Croissant Breakfast Sandwiches
Grease your baking dish. Eggs can stick to the bottom of the pan, so don’t skip the nonstick cooking spray or butter.
Bake them uncovered. The eggs need to cook and set properly, so bake the sandwiches uncovered. If the croissants become too brown, loosely tent the tops with foil toward the end instead.
Let them cool before freezing. This helps prevent condensation from making your croissants soggy.
Freeze them individually. You’ll be able to grab exactly as many sandwiches as you need instead of thawing the entire batch.
Reheat in an air fryer or toaster oven. These are my favorite methods because they help bring back the texture of the croissant.
Customize the filling. Use whatever cheese and cooked breakfast protein your family likes.

Can I make croissant breakfast sandwiches ahead of time?
Absolutely. You can bake the entire batch ahead of time and refrigerate the sandwiches for the next few days or freeze them for longer storage.
How do you reheat frozen croissant breakfast sandwiches?
I prefer reheating them in an air fryer or toaster oven because it helps warm the center while bringing back some of the crisp texture on the outside of the croissant. Heat until the egg and filling are completely warmed through.
Do I cover croissant breakfast sandwiches while baking?
No. Bake these croissant egg sandwiches uncovered at 200°C / 400°F for 20–25 minutes. If the tops begin browning too much before the eggs are completely set, loosely tent them with foil toward the end of the baking time.
How do I know when the eggs are done?
The egg should be completely set in the center of the baking dish with no runny or liquid egg remaining. If needed, give the sandwiches a few additional minutes in the oven.
What cheese is best for croissant breakfast sandwiches?
Use a cheese that melts well and that your family enjoys. Cheddar, mozzarella, Swiss, and Gouda are all good options.
Can I make these without turkey?
Yes. Leave out the turkey for an easy egg and cheese croissant sandwich, or substitute another fully cooked breakfast protein.
