Overnight Croissant Breakfast Casserole Recipe

Introduction

This Overnight Croissant Breakfast Casserole is a delightful and easy make-ahead dish perfect for busy mornings or brunch gatherings. Soft croissants soaked in a savory egg mixture, combined with cheese and ham or bacon, create a warm and comforting meal ready right from the oven.

Ingredients

• 4 large croissants, torn into bite-sized pieces
• 6 large eggs
• 1 ½ cups milk
• 1 ½ cups shredded cheese (Cheddar or Swiss work well)
• 1 cup diced ham or cooked bacon

Instructions

1. Step 1: In a large bowl, whisk together the eggs and milk until fully combined. Stir in the shredded cheese and diced ham or bacon.
2. Step 2: Place the torn croissant pieces in a greased baking dish, spreading them evenly.
3. Step 3: Pour the egg mixture over the croissants, pressing gently to help the bread absorb the liquid.

6. Step 6: Let the casserole sit for a few minutes before serving to make slicing easier.

Tips & Variations

• Substitute croissants with brioche or other soft bread for a different texture.
• Add vegetables like spinach, bell peppers, or mushrooms for extra flavor and nutrition.
• Use a mix of cheeses to create a richer taste.
• For a vegetarian version, omit the ham or bacon and add more vegetables.

FAQs

Can I prepare this casserole with fresh bread instead of croissants?

Yes, fresh soft bread like brioche or even dinner rolls can be used, but croissants add a buttery, flaky texture that enhances the dish.

Is it necessary to refrigerate the casserole overnight?

Refrigerating overnight allows the croissants to soak up the egg mixture fully, resulting in a more cohesive and flavorful casserole. If short on time, letting it sit for at least 1 hour can still work.

Ingredients

Scale 1x2x3x

Basic Ingredients

• 4 large croissants, torn into bite-sized pieces
• 8 large eggs
• 2 cups whole milk
• 2 cups shredded cheese (cheddar, Swiss, or your choice)
• 1 cup cooked ham or crispy bacon, chopped
• Salt and freshly ground black pepper, to taste

Instructions

1. Prepare the croissants and protein: Tear the croissants into bite-sized pieces and chop the cooked ham or bacon. This forms the base and savory element of the casserole.
2. Mix the custard: In a large bowl, whisk together eggs, milk, salt, and pepper until fully combined and slightly frothy. This mixture will soak into the croissants and create the creamy texture.
3. Assemble the casserole: In a greased baking dish, layer the croissant pieces, ham or bacon, and half of the shredded cheese. Pour the egg and milk mixture evenly over the layers, then sprinkle the remaining cheese on top to create a delicious topping.
4. Refrigerate overnight: Cover the baking dish tightly with plastic wrap and refrigerate for at least 8 hours or overnight. This allows the croissants to absorb the custard and flavors to meld.
5. Bake the casserole: Remove the casserole from the refrigerator about 30 minutes before baking to take off the chill. Preheat your oven to 350°F (175°C). Bake uncovered for 45 to 55 minutes, or until the eggs are set, the top is golden brown, and a knife inserted in the center comes out clean.
6. Serve: Let the casserole cool for a few minutes before slicing and serving. Enjoy warm for a hearty breakfast or brunch option.

Notes

• You can substitute the ham or bacon with sausage or keep it vegetarian by omitting the meat.
• Use day-old croissants for best texture and absorption.
• Add vegetables like spinach, bell peppers, or mushrooms for extra nutrition and flavor.
• Ensure the casserole is fully cooked by checking that the center is set and no longer jiggly.
• This recipe can be doubled for larger groups, just adjust the baking time accordingly.
