For the Casserole

Croissants – Use fresh, medium-sized croissants from the bakery for that perfect flaky base.
Eggs – Opt for large, fresh eggs to provide a deliciously rich binder and protein boost.
Half and Half or Whole Milk – Choose half and half for extra creaminess, or use whole milk for a lighter twist.
Dijon Mustard – Adds a wonderful tanginess; if you’re not a fan, try a different mustard—just remember Dijon gives the best depth!
Salt – A pinch is all you need to enhance the flavors, but be cautious as ham is naturally salty.
Deli or Leftover Ham – Go for a slightly smoky ham to add heartiness and flavor to the dish.
Shredded Swiss or Gruyere Cheese – These cheeses melt beautifully, but mozzarella can be a lighter alternative.

For Serving

Powdered Sugar – Optional but adds a touch of sweetness and presentation magic when dusted over the baked casserole.

Step‑by‑Step Instructions for Ham and Cheese Croissant Breakfast Casserole

Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Lightly grease a 9×6 or 9×11 baking dish with cooking spray or butter to ensure the casserole doesn’t stick. This step is crucial for easy serving later. Gathering your equipment ahead streamlines the process and makes preparation smooth as you embark on creating your Ham and Cheese Croissant Breakfast Casserole.

Step 2: Layer the Croissants
Carefully tear the fresh croissants in half and arrange them in your prepared baking dish. Make sure to layer them evenly to create a delightful base. Sprinkle deli or leftover ham pieces generously around the croissant halves, ensuring every bite will be flavorful. Finish this layer by generously sprinkling shredded Swiss or Gruyere cheese over the croissants and ham for a gooey, melty topping that enhances the casserole’s richness.

Step 3: Whisk the Egg Mixture
In a mixing bowl, whisk together 6 large eggs, 1 cup of half and half (or whole milk), 2 tablespoons of Dijon mustard, and a pinch of salt. Whisk until everything is fully combined, and the mixture is smooth. This egg mixture acts as the binder for your Ham and Cheese Croissant Breakfast Casserole, adding creaminess and helping the dish set. Ensure that you achieve a uniform consistency before proceeding.

Step 4: Combine Layers with Egg Mixture
Once your egg mixture is ready, pour it evenly over the layered croissants, ham, and cheese in the baking dish. Take your time with this step, ensuring that the egg mixture seeps into all the layers, enhancing the flavors throughout. For an even soak, gently press down the croissants with a spatula, allowing them to absorb that delicious, creamy goodness before covering the casserole.

Step 5: Chill for Flavor
Cover the baking dish with aluminum foil and place it in the refrigerator for at least 30 minutes, or overnight if time allows. Chilling allows the ingredients to meld together, enhancing the flavors and texture of your Ham and Cheese Croissant Breakfast Casserole. This make-ahead step ensures that when you bake it, every element will shine beautifully.

Step 6: Bake the Casserole
After chilling, remove the casserole from the refrigerator and place it in your preheated oven. Bake it covered with foil for 20 minutes, then carefully remove the foil and continue baking for an additional 10-15 minutes. You’re looking for a golden top and bubbly edges—this visual cue indicates your casserole is perfectly cooked and ready for the final touch!

Step 7: Serve and Enjoy
Once baked to perfection, allow the casserole to rest for about 5 minutes before slicing. This resting period helps it set up nicely for serving. For a delightful finishing touch, dust the top with powdered sugar, adding a sweet contrast to the savory layers below. Your Ham and Cheese Croissant Breakfast Casserole is now ready to impress at any breakfast table!

Expert Tips for Ham and Cheese Croissant Breakfast Casserole

Overnight Soak: Allowing your casserole to chill in the refrigerator overnight enhances flavor and texture, making it a must for this dish.
Perfect Baking Time: Keep an eye on the baking process; overcooking can lead to a dry casserole. Look for a golden top and bubbly edges as signs of doneness.
Sodium Control: Use low-sodium ham to manage saltiness, especially since cheese also contributes salt. Balance is key for a delightful meal!
Fresh Ingredients: Choose high-quality, fresh croissants and ingredients for the best flavor. Stale croissants can lead to a soggy texture.

Ham and Cheese Croissant Breakfast Casserole Recipe FAQs

How do I choose the right croissants for the casserole?
Absolutely! For the best results, opt for fresh medium-sized croissants from your local bakery. Look for croissants that are golden brown with a flaky texture—avoid any that look stale or overly soft, as they may not hold up well in the casserole.

How should I store leftovers of the casserole?
I recommend placing leftovers in an airtight container in the refrigerator. They will stay fresh for up to 3 days. When reheating, simply warm individual portions in the microwave or pop them in the oven until heated through for the best experience!

Can I freeze the casserole for later use?
Yes, indeed! To freeze, tightly wrap the casserole in plastic wrap and then in aluminum foil to prevent freezer burn. It can be stored in the freezer for up to 3 months. When you’re ready to enjoy it, thaw it overnight in the refrigerator before reheating.

What if my casserole doesn’t set properly while baking?
If you notice that the casserole is still too wet or hasn’t set after baking, it may need a bit more time in the oven. Continue baking until you see a golden top with bubbling edges, which indicates that it is done. Also, make sure you used enough eggs in the mixture as they act as the binder for the dish.

Is this casserole suitable for those with dietary restrictions?
Absolutely! You can make it gluten-free by using gluten-free croissants and checking that your ham and cheese are also gluten-free friendly. If there are dairy allergies, try using a dairy-free milk alternative and non-dairy cheese. Always read labels to ensure the ingredients fit your dietary needs!

Can I prepare this casserole the night before serving?
Yes, you can! In fact, allowing the casserole to soak in the fridge overnight helps meld the flavors beautifully. Just follow the instructions up to the chilling step, then bake it fresh in the morning. This makes your brunch prep a breeze!
