Ingredients You’ll Need
Gathering the right ingredients for this Easy French Croissant Breakfast Bake Recipe is the first step toward a scrumptious and visually appealing dish. Each component plays a vital role in creating that perfect balance of creaminess, savoriness, and deliciously crispy edges.
- Cooking spray: To ensure your bake doesn’t stick and comes out perfectly crisp on the edges.
- 4 ounces Gruyère cheese, divided: This nutty, slightly sweet cheese melts beautifully and adds depth of flavor.
- 6 large eggs: The rich custard base that binds everything into one luscious dish.
- 1 1/2 cups half-and-half: Adds creaminess and tenderizes the croissants for the perfect bite.
- 2 teaspoons Dijon mustard: Adds a subtle tang and complexity to the custard mixture.
- 1 teaspoon kosher salt: To enhance all the flavors of your ingredients.
- 1/2 teaspoon freshly ground black pepper: Offers a gentle warmth to balance the richness.
- 8 croissants (about 22 ounces): The star of the dish, providing buttery, flaky layers that soak up the custard.
- 6 slices deli ham (about 5 ounces): Adds a smoky, savory punch that pairs perfectly with the cheese.
- 2 tablespoons unsalted butter, melted: For brushing on top and adding golden, aromatic richness.

- 2 teaspoons finely chopped fresh herbs: Such as chives, rosemary, thyme, or a mix, to add fresh, herbaceous notes.
How to Make Easy French Croissant Breakfast Bake Recipe
Step 1: Prepare Your Baking Dish and Cheese
Preheat your oven to 350°F. Lightly coat a 9×13-inch baking dish with cooking spray to prevent sticking and help with crisping. Now, take 3 ounces of the Gruyère cheese and slice it into thin pieces to tuck between layers, while grating the remaining ounce for sprinkling on top. This ensures the cheese melts evenly and creates irresistible pockets of gooey indulgence.
Step 2: Whisk Together the Custard Mixture
In a large bowl, whisk together 6 large eggs, 1 1/2 cups half-and-half, 2 teaspoons Dijon mustard, 1 teaspoon kosher salt, and 1/2 teaspoon freshly ground black pepper. This custard will soak the croissants and infuse the entire bake with creamy, savory goodness as it cooks.
Step 3: Dip and Layer the Croissants
Cut your 8 croissants crosswise into 3 equal pieces—this will give you 24 bite-sized chunks. Working one piece at a time, immerse the croissant chunks in the custard mixture, allowing them to soak up that creamy texture, then arrange them snugly in your prepared baking dish. Tight packing helps the bake maintain a beautiful structure and ensures every bite is bursting with flavor. After placing all pieces, pour any remaining custard evenly over the top for extra moisture.
Step 4: Add Ham and Cheese Rosettes
Halve each slice of deli ham, then fold and roll each piece into a charming little rosette. Nestle these savory flowers between the croissant pieces around the pan. Add your thin slices of Gruyère in the same way, tucking them in to create delightful pockets of melted cheese throughout the dish. Finally, sprinkle the grated Gruyère evenly over the top for a golden crust.
Step 5: Bake Until Golden and Set
Place your baking dish in the oven and bake for 40 to 45 minutes, until the center is set and slightly puffed, and the croissants turn a gorgeous golden-brown. You’ll know it’s done when the aroma fills your kitchen with irresistible signals that breakfast is about to be served in style.
Step 6: Finish with Herb-Garlic Butter
Just minutes before your casserole is ready, mix 2 tablespoons melted unsalted butter with 1 grated small garlic clove, 2 teaspoons of finely chopped fresh herbs, and a pinch of kosher salt. Brush this fragrant butter over the hot bake as soon as it comes out of the oven. This finishing touch adds irresistible savory notes and a shiny, inviting glaze that will impress any guest at the table.
How to Serve Easy French Croissant Breakfast Bake Recipe
Garnishes
Fresh herbs like chives or thyme sprinkled on top right before serving add a pop of color and fresh, bright flavor that contrasts beautifully with the rich cheese and ham. A light drizzle of maple syrup can be surprisingly delightful if you enjoy a sweet and savory combo.
Side Dishes
This bake pairs wonderfully with a crisp green salad dressed lightly with lemon vinaigrette or a bowl of fresh seasonal fruit to balance out its richness. For a heartier brunch, roasted potatoes or sautéed mushrooms make excellent companions, turning your breakfast into a feast everyone will remember.
Creative Ways to Present
Serve this Easy French Croissant Breakfast Bake Recipe straight from the baking dish for a rustic family-style vibe, or slice it into individual portions and plate with a sprinkle of extra herbs and a small ramekin of homemade jam for a gourmet touch. You can even add edible flowers for a stunning presentation that will wow guests visually and gastronomically.
Make Ahead and Storage
Storing Leftovers
After enjoying your breakfast bake, store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors will meld beautifully overnight, making for an easy and delicious next-day meal.
Freezing
If you want to save some for later, allow the dish to cool completely, then wrap it tightly in plastic wrap and foil before freezing. It will keep well for up to 2 months. Thaw overnight in the fridge before reheating to enjoy near-fresh flavor.
Reheating
Reheat individual portions in the microwave for about 1 to 2 minutes or warm the whole dish in a 350°F oven for 15 to 20 minutes until heated through and crispy on top. This keeps the textures just as delightful as the first serving.
FAQs
Can I use a different cheese instead of Gruyère?
Absolutely! While Gruyère offers a classic nutty flavor perfect for this bake, you can substitute with Swiss, Emmental, or even a sharp cheddar for a bolder taste. Just keep in mind the meltability and flavor profile to maintain balance.
What if I don’t have half-and-half?
No worries! You can use equal parts whole milk and heavy cream as a substitute. This blend mimics half-and-half’s richness, ensuring your custard remains creamy and luscious.
Can I make this gluten-free?
Yes, simply swap out the croissants for gluten-free croissants available at specialty stores or use a gluten-free bread option. Texture may vary slightly, but the overall flavor experience will still be delightful.
Is it possible to prepare this recipe the night before?
Definitely. Assemble the dish without baking it, cover tightly with plastic wrap, and refrigerate overnight. In the morning, bake it as directed, adding a few extra minutes to cooking time if the casserole is cold.
How can I make the bake more indulgent?
Try adding sautéed mushrooms, caramelized onions, or even a sprinkle of crispy bacon bits before baking. These add layers of texture and flavor, elevating your Easy French Croissant Breakfast Bake Recipe to a decadent level.

Topping
- 2 tablespoons unsalted butter, melted
- 1 small clove garlic, grated
- 2 teaspoons finely chopped fresh herbs (chives, rosemary, thyme, or a combination)
- Cooking spray
Instructions
- Preheat Oven and Prepare Dish: Heat the oven to 350°F. Lightly coat a 9×13-inch baking dish with cooking spray. Cut 3 ounces of the Gruyère cheese into thin slices and grate the remaining 1 ounce on the large holes of a box grater.
- Mix Egg Custard: In a large bowl, whisk together 6 large eggs, 1 1/2 cups half-and-half, 2 teaspoons Dijon mustard, 1 teaspoon kosher salt, and 1/2 teaspoon freshly ground black pepper until fully combined and smooth.
- Prepare Croissants: Cut each croissant crosswise into 3 pieces, making 24 pieces total. Dip each croissant piece one at a time into the custard mixture, ensuring they are well-coated, then arrange them tightly together in the prepared baking dish. Once all pieces are in the dish, pour any remaining custard evenly over the top.
- Add Ham and Cheese: Cut the 6 slices of deli ham in half. Fold each half in half again and roll into a rosette shape. Nestle these ham rosettes evenly between the croissant pieces around the baking dish. Place the sliced Gruyère cheese slices between the croissant pieces, then sprinkle the grated Gruyère over the entire top of the bake.
- Bake: Place the baking dish in the oven and bake for 40 to 45 minutes, or until the center is set, slightly puffed, and the croissants are golden brown on top.
- Prepare Garlic Herb Butter and Finish: A few minutes before the bake is done, mix 2 tablespoons melted unsalted butter, 1 small grated garlic clove, 2 teaspoons finely chopped fresh herbs, and a pinch of kosher salt in a small bowl. When the casserole is out of the oven, brush this garlic herb butter evenly over the top to add extra flavor and shine.
Notes
- Use day-old or slightly stale croissants for better absorption of the custard without becoming too soggy.
- Feel free to use a combination of fresh herbs like thyme, rosemary, and chives for a more complex flavor.
- Gruyère cheese adds a nutty and creamy flavor, but Swiss or cheddar can be substituted if unavailable.
- Leftovers can be refrigerated and reheated; add a little cream to keep moist when reheating.
- Ensure the egg custard is well whisked for a smooth bake with no egg lumps.
