Gathering the Ingredients

To start this comforting journey, gather the following ingredients:

6 large croissants, torn into pieces
8 large eggs
2 cups milk
1 cup shredded cheese (cheddar or Gruyère)
1/2 cup diced ham or bacon
1/2 cup diced bell peppers
1/2 cup diced onions
1 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon garlic powder
1 teaspoon dried herbs (like thyme or parsley)

Feel free to personalize this recipe to suit your tastes. For instance, if you prefer a lighter flavor, consider using low-sodium broth instead of regular salt. The beauty of cooking lies in the details and the ability to adapt to what feels right for you.

Step-by-Step Directions

Preheat the oven to 350°F (175°C). Grease a 9×13 inch baking dish, ensuring the bottom and sides are well coated to prevent sticking.
In a large bowl, combine the torn croissant pieces, shredded cheese, diced ham (or bacon), bell peppers, and onions. Toss gently to combine, allowing the ingredients to mingle.
In another bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and dried herbs. This mixture will bring the casserole to life.
Pour the egg mixture over the croissant mixture, ensuring everything is well coated. Take your time to mix thoroughly, as this will ensure even flavor distribution.
Cover the dish with plastic wrap and refrigerate overnight. This resting period allows the flavors to meld beautifully.
In the morning, remove the casserole from the refrigerator and let it sit for 10 minutes. This brief pause helps it come closer to room temperature prior to baking.
Bake uncovered for 30-35 minutes, or until the top is golden brown and the eggs are set. Watching the transformation is the kind of moment that fills your heart with satisfaction.
Allow to cool for a few minutes, then cut into squares and serve warm. Each piece should be rich and comforting—perfect for sharing.

Savannah’s Slow-Cooker Tips

Choose Quality Croissants: The base of your casserole will shine when you start with good-quality croissants. Opt for freshly baked ones from your local bakery for the best results.
Layer Wisely: When adding ingredients, layer them to ensure an even distribution of flavors and textures. This simple step makes a difference in the overall enjoyment of the dish.
Taste as You Go: Don’t hesitate to taste your egg and milk mixture before pouring it over the croissants. Adjust seasoning as needed; cooking should feel intuitive and fun.
Flexible Flavors: The ingredients in this casserole are flexible. Substitute with your favorites or what you have on hand. Spinach, sun-dried tomatoes, or even leftover roasted vegetables can find a home in this dish.
Let It Rest: Allowing the casserole to sit before slicing not only helps with easier serving but also enhances the flavor. Patience rewards you with an impeccable texture.

Family Twists on Overnight Croissant Breakfast Casserole

Family traditions often influence how recipes evolve. In my family, we incorporate a bit of spice with a dash of hot sauce mixed into the egg mixture—this little addition brings a delightful kick to our casserole.

In other Southern kitchens, you may find the use of spicy sausage or even a blend of cheeses to enhance the flavor profile further. Some regions even add a topping of crumbled cornbread for a twist, creating a fusion of textures that differ from the traditional recipe. No matter the variations, each family makes it their own, creating a tapestry of flavors built on love and shared experiences.
