Ingredients List
To create your Croissant Breakfast Casserole, you’ll need the following ingredients:
- Croissants:Â 6 large, stale croissants (day-old works best for texture)
- Eggs:Â 6 large eggs
- Milk:Â 1 cup (whole or 2% for creaminess)
- Cheese:Â 1 cup shredded cheese (cheddar, mozzarella, or a blend)
- Spinach:Â 1 cup fresh spinach, chopped (or substitute with kale)
- Cooked Bacon or Sausage:Â 1 cup, crumbled (optional; can use turkey bacon for a healthier option)

- Nutmeg:Â A pinch (for a warm, aromatic flavor)
- Fresh Herbs:Â Chopped chives or parsley for garnish (optional)

Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures your casserole cooks evenly and develops a golden, bubbly top.
Step 2: Prepare the Croissants
Tear the stale croissants into bite-sized pieces and place them in a greased 9×13-inch baking dish. The croissants should fill the bottom of the dish generously, creating a fluffy base.
Step 3: Whisk the Egg Mixture
In a large bowl, whisk together the eggs, milk, salt, black pepper, and nutmeg. This mixture will bind the casserole and add richness.
Step 4: Add the Fillings
Stir in the chopped spinach, crumbled bacon or sausage, and shredded cheese into the egg mixture. Ensure everything is well combined for even distribution of flavors.
Step 5: Combine and Bake
Pour the egg mixture over the croissant pieces in the baking dish. Gently press the croissants down to soak them in the egg mixture. Bake in the preheated oven for 30-35 minutes, or until the casserole is set and lightly golden on top.
Step 6: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for about 5 minutes. Garnish with fresh herbs before serving. Enjoy your delicious Croissant Breakfast Casserole warm!
