Sweet breakfast casserole with croissants 

Are you a sweet or savory breakfast type? 

Personally, I refuse to pick a side. Some days are for fruit, yogurt, and pastries galore! Others, I am thrilled to dig into some scrambled eggs or a fancy avocado toast. What can I say – I’m a woman of multitudes. 

So, while I’ve shared a savory croissant breakfast casserole in the past, it was only fair to the other side that I came up with a little something sweet. 

My sweet croissant breakfast casserole is every sweet tooth’s dream, made with spiced cream cheese icing and seasonal berries. I even add protein-rich eggs to keep you full and satisfied for the day ahead!

Ingredients needed

Here’s a little bit about everything that goes into my sweet croissant breakfast casserole. 

• Croissants: The base of this recipe is 8 large croissants. I bake them until they’re extra crispy so that they keep their texture, even when mixed with the other ingredients. 
• Cream cheese: For sweet cream cheese icing, I use an 8 oz pack of softened cream cheese. It’s super creamy and slightly tart. 
• Sugar: I use ¾ cup sugar to give this recipe just the right amount of sweetness. Both white and brown sugar would work well. 
• Cinnamon: I love adding warm spices to my recipes; they give dishes such a comforting depth. I use 1 tsp of cinnamon in this recipe for a woodsy touch. 
• Nutmeg: For additional depth, I use ¼ tsp in my cream cheese mixture. Earthy and sweet, it’s the perfect flavor enhancer. 
• Salt: Salt is such a powerhouse. Just a pinch of salt brings all of the flavors together, making everything taste just a little bit better. 
• Eggs: While it may seem like an odd ingredient in a sweet casserole, this recipe calls for 4 eggs. They add great protein content to this dish, making it a more nutritionally-complete meal. 
• Vanilla: Vanilla extract is an absolute essential in any of my baking recipes. This dish calls for 2 tsp. 
• Milk: 1 cup of milk helps thin the cream cheese mixture and adds moisture to this sweet casserole. 
• Mixed berries: The final ingredient in this dish is non-negotiable – 3 cups of mixed berries! I like to use equal parts of blueberries, blackberries, and raspberries, though you can use whichever is your favorite (or on sale!). 

Kitchen tools required

You’ll need a few common kitchen tools to bake this dish, including:

• Large mixing bowl
• Hand or stand mixer
• 9×13 dish
• Aluminum foil 

Also, gather a few measuring cups, including 1 cup, ¼ cup, 1 tsp, and ¼ tsp,

How to make sweet breakfast casserole with croissants 

First up, preheat your oven to 450F. 

Rip up your croissants into bite-sized chunks and add them to a baking sheet. Pop them in your preheated oven and bake for 8-10 minutes until they’re golden and crispy. Set aside to cool.

While your croissants are crisping in the oven, prep your cream cheese icing! Add cream cheese, sugar, cinnamon, nutmeg, and salt to a large mixing bowl. Mix using a hand mixer or stand mixer until combined.

Then, add eggs and vanilla and beat until the mixture is smooth. Finally, beat in the milk until creamy. 

Add your cooled croissants to a baking dish and top with berries on your cream cheese egg mixture. Aim for an even coating. 

Gently press the croissants into the egg mixture and cover your dish with a sheet of aluminum foil. Let it sit overnight or at least two hours before you bake your dish. Then, bake for 50-55 minutes. You’ll know it’s done when the egg mixture has set and the croissants are a gorgeous golden color. 

Let your sweet breakfast casserole cool for 20 minutes before digging in!

How do I serve sweet croissant breakfast casserole?

This sweet breakfast casserole is delicious on its own but can be even more tasty with a few toppings. 

I recommend serving with powdered sugar, additional fresh berries, and a healthy drizzle of maple syrup.

How do I make this recipe dairy-free?

To make this breakfast casserole dairy-free, you’ll need to substitute two ingredients – milk and cream cheese. 

For milk, swap with your favorite non-dairy alternative, like oat milk, almond milk, or soy milk. Make sure that it’s unflavored and unsweetened. 

Dairy-free cream cheese is also very easy to find. I recommend the Violife creamy block; its flavor and texture are just like the real thing. 

Storing Leftovers

To store your sweet croissant breakfast casserole, let it cool completely. Tightly cover your baking dish with cling wrap, or transfer the casserole to an airtight container. 

This dish will last in the refrigerator for up to four days. 

To reheat, you can microwave a serving for 1-2 minutes until warm through. For a better texture, however, I recommend baking it in the oven at 350F for about 15 minutes. 

Can I meal prep this recipe? 

This recipe is pretty perfect for meal prep. Prepare it Sunday night and bake it Monday morning for a sweet start to your week. 

It’ll last for up to four days, though it’s so tasty, I doubt it’ll make it past day two!

Can I freeze sweet breakfast casserole?

You can freeze this dish for up to two months. To do so, transfer your breakfast casserole to an airtight container, or several for individual servings.
