Step‑by‑Step Instructions for Croissant Breakfast Casserole
Step 1: Prepare Baking Dish
Preheat your oven to 350°F (175°C). While the oven is heating up, grease a 9×13-inch baking dish with nonstick spray to ensure your Croissant Breakfast Casserole comes out easily after baking. This step is crucial for a hassle-free serving experience!
Step 2: Cook Bacon
In a large skillet over medium heat, cook the bacon until it reaches crispy perfection, about 4-5 minutes. As the bacon sizzles, it will release its savory aroma, making your kitchen feel cozy. Once crispy, transfer the bacon directly into the prepared baking dish, allowing the delightful drippings to add flavor to the casserole.
Step 3: Layer Ingredients
Sprinkle half of the Gruyere and white cheddar cheese over the crispy bacon in the baking dish. Next, take your stale croissants and tear them into bite-sized pieces, scattering them evenly over the cheese. Allow some croissant pieces to stick up a bit for a rustic presentation, which will add a lovely texture to your Croissant Breakfast Casserole.
Step 4: Make Egg Mixture
In a medium-sized bowl, whisk together the eggs, whole milk, heavy cream, sage, Dijon mustard, kosher salt, and black pepper until fully combined and frothy. This creamy custard will bind the casserole together beautifully. Pour the egg mixture evenly over the layered croissants and cheese, ensuring everything is well coated for maximum flavor.
Step 5: Bake
Carefully place the casserole in the preheated oven and bake for 40-45 minutes. You’ll know it’s ready when the top is golden and set, and a toothpick inserted in the center comes out clean. Keep an eye on it; if it browns too quickly, cover it loosely with foil. This indulgent Croissant Breakfast Casserole will fill your kitchen with an irresistible aroma!
Step 6: Cool and Garnish
Once baked, remove the casserole from the oven and let it cool for 5-10 minutes to set. This resting time will make serving much easier. Before diving in, sprinkle freshly chopped chives on top for a pop of color and a burst of mild onion flavor, elevating your Croissant Breakfast Casserole to a delicious presentation.

Croissant Breakfast Casserole Recipe FAQs
What type of croissants should I use for the casserole?
Using stale or day-old croissants is best for this casserole. Fresh croissants can become overly soggy when mixed with the egg custard, while stale ones provide a better structure and texture, resulting in a delightful contrast between crispy and custardy.
How should I store leftovers from the Croissant Breakfast Casserole?
Leftovers can be stored in an airtight container in the fridge for up to 3 days. Make sure to allow the casserole to cool completely before sealing it to maintain its moisture and texture.

Absolutely! To freeze, wrap portions tightly in plastic wrap, then aluminum foil, or use a freezer-safe container. It can be frozen for up to 2 months. When you’re ready to enjoy it again, simply thaw it overnight in the refrigerator before reheating.
What should I do if my casserole browns too quickly while baking?
Keep an eye on your casserole during baking! If the top starts to brown too fast—generally around the 30-minute mark—simply cover the dish loosely with aluminum foil. This will prevent it from burning while allowing the inside to continue cooking evenly.
Can this casserole be made ahead of time?
Yes! To make it ahead, you can assemble the casserole but keep the egg mixture separate until you’re ready to bake. This method preserves the croissants’ texture and ensures that your Croissant Breakfast Casserole bakes up deliciously every time.
Are there any dietary considerations I should be aware of?
If cooking for guests with dietary restrictions, be mindful of allergies to dairy (in the cheeses and cream) or gluten (in the croissants). You could potentially substitute gluten-free bread for croissants and use dairy alternatives to make an allergen-friendly version of this dish.
