How to Make Ham & Cheese Croissant Bake
-
Preheat & Prepare Dish: Heat your oven to 350°F (175°C). Grease a baking dish thoroughly with butter or non-stick spray to prevent any sticking during baking.
-
Prep Croissants: Slice the croissants horizontally in half. Using day-old or stale croissants is best, as they absorb the custard mixture wonderfully without becoming soggy.
-
Layering: Place the bottom halves of the croissants evenly in the dish. Next, layer the diced ham and shredded cheese generously on top before adding the croissant tops to create a delicious layered structure.
-
Mix Custard: In a large bowl, whisk the eggs, milk, Dijon mustard, salt, pepper, and garlic powder (if using) until everything is fully combined and you see a light froth develop—this ensures a smooth custard!
-
Pour Custard: Gently pour the egg mixture over the layered croissant assembly, making sure each piece gets soaked. Press down lightly with your hands to maximize the absorption of the custard.
-
Bake Covered: Cover your dish tightly with foil and bake for 20 minutes to allow the custard to set gently without drying out, which helps maintain a moist texture.
-
Brown Top: After 20 minutes, remove the foil and continue to bake for an additional 10-15 minutes. Look for the custard to be fully set and the top to turn golden brown and slightly crisp.
-
Rest Before Serving: Once out of the oven, let your Ham & Cheese Croissant Bake sit for about 10 minutes. This resting period helps the custard firm up, making slicing cleaner and enhancing the dish’s overall texture.
-
Garnish and Serve: Optionally, sprinkle freshly chopped parsley over the top for a touch of color and freshness before serving to your eager guests.
Optional: Add a dash of hot sauce for a spicy kick before serving.

Expert Tips for Ham & Cheese Croissant Bake
- Optimal Croissant Choice: Using day-old or slightly stale croissants: This enhances custard absorption, preventing any sogginess or dryness in your Ham & Cheese Croissant Bake.
- Ensure Even Soaking: Gently pressing down the croissant layers after pouring the custard: This guarantees uniform texture and flavorful soaking throughout the casserole.
- Covering Technique: Keep the dish covered for the first 20 minutes of baking: This prevents the custard from drying out and results in a creamier final product.
- Perfecting the Top: Remove the foil during the last 10-15 minutes of baking: This allows for a beautifully golden and slightly crisp top without overcooking the custard underneath.
- Resting Time Matters: Let the dish rest for 10 minutes after baking: This allows the custard to set fully, making it easier to slice and serve.
- Adjust Your Seasonings: Taste and adjust salt and pepper: Remember, the ham and cheese can add saltiness, so it’s essential to season carefully.
How to Store and Freeze Ham & Cheese Croissant Bake
- Fridge: Store leftovers in an airtight container for up to 3 days. This will keep the flavors fresh and the texture enjoyable for your next meal.
- Freezer: For longer storage, wrap the casserole tightly in plastic wrap and then in aluminum foil. It can be frozen for up to 3 months.
- Reheating: When ready to enjoy again, thaw in the fridge overnight and reheat in the oven at 350°F (175°C) until warmed through—about 20 minutes.
- Avoid Sogginess: Be sure to let the Ham & Cheese Croissant Bake cool completely before refrigeration or freezing to prevent excess moisture buildup.

Ham & Cheese Croissant Bake Recipe FAQs
What type of croissants should I use for the Ham & Cheese Croissant Bake?
Using day-old or slightly stale croissants is highly recommended. They absorb the custard beautifully without becoming soggy, ensuring the perfect balance of texture. Fresh croissants can be used in a pinch, but they may not soak up the custard as effectively.
How long can I store the Ham & Cheese Croissant Bake in the refrigerator?
You can store leftovers in an airtight container for up to 3 days. This helps maintain the dish’s flavors and keeps the texture enjoyable for a few meals after preparation. Just make sure to reheat gently for best results.
Can I freeze the Ham & Cheese Croissant Bake?
Absolutely! To freeze, wrap the completely cooled casserole tightly in plastic wrap, followed by aluminum foil. This method prevents freezer burn. You can store it for up to 3 months. When you’re ready to enjoy it, thaw overnight in the refrigerator before reheating.
How should I reheat the Ham & Cheese Croissant Bake?
To reheat, preheat your oven to 350°F (175°C). Place the casserole in the oven, covered with aluminum foil, for about 20 minutes until warmed through. Since the custard sets slightly after cooling, this gentle reheating method keeps it from drying out.
What if my Ham & Cheese Croissant Bake turns out too soggy?
If you find the casserole is too soggy, it could be due to using overly fresh croissants or not allowing adequate soaking time. To remedy this for future bakes, ensure you’re using day-old croissants and press the layers down after pouring in the custard to guarantee even absorption.
Can I modify the recipe for dietary restrictions?
Yes! You can easily customize this recipe to accommodate dietary needs. For gluten-free options, use gluten-free croissants. If you’re vegetarian, you can omit the ham entirely and replace it with veggies like sautéed spinach or mushrooms for added flavor. Always check for allergens in the cheese and milk you choose to use!
