What you’ll need

Gather these items to make this irresistible breakfast casserole:

6 croissants, torn into pieces
6 large eggs
2 cups milk
1 cup shredded cheese (e.g., cheddar or Swiss)
1/2 cup diced ham or cooked bacon (optional)
1/4 cup chopped fresh herbs (e.g., chives or parsley)
Salt and pepper to taste

Feel free to swap out the cheese or herbs based on your preferences. No ham or bacon? Try sautéed vegetables for a delicious vegetarian version!

Directions to follow

Start by whisking together the eggs and milk in a large mixing bowl. Don’t forget to season with salt and pepper to elevate the flavor.
Grease a 9×13 inch baking dish with butter or oil. Layer the torn croissant pieces evenly along the bottom.
If you’re using diced ham or bacon, sprinkle it over the croissants, then follow up with a generous layer of cheese and fresh herbs.
Carefully pour the egg mixture over the layers, ensuring that every piece is well soaked.
Cover the dish tightly with foil and place it in the refrigerator overnight.
When you’re ready to bake, preheat your oven to 350°F (175°C).
Bake the casserole covered for about 30 minutes, then remove the foil and bake for an additional 15-20 minutes until the top is beautifully golden and the casserole is fully set.
Allow it to cool slightly before slicing and serving.

Best ways to enjoy it

To serve, cut the casserole into squares and garnish with extra herbs for a fresh touch. Pair it with a light fruit salad or freshly squeezed orange juice to balance the richness. For those who enjoy a little heat, serve with a drizzle of hot sauce or sriracha.

Keeping leftovers fresh

After your meal, allow any leftovers to cool completely before storing. Place them in an airtight container in the refrigerator, where they’ll stay fresh for up to 3 days. If you’d like to store the casserole for a longer period, you can freeze individual portions. Just be sure to wrap them well to prevent freezer burn.

Helpful cooking tips

Always give the casserole enough time to soak overnight; this step helps the croissants become incredibly soft and flavorful.
If you prefer a lighter version, substitute whole milk with skim milk or a dairy-free alternative.
Customize your toppings! Adding a layer of spinach or bell peppers can enhance the nutrition and flavor profile.
