An Overnight Bacon Brunch Casserole is a delightful and convenient dish that combines the savory flavors of crispy bacon, melted cheese, and tender brioche bread, all enveloped in a rich egg custard. Perfect for breakfast or brunch, this make-ahead casserole allows you to enjoy a hearty meal with minimal morning effort.
Ingredients:
For the casserole:
- 1 pound brioche bread, cut into 1-inch cubes
- 1 pound bacon, diced
- 8 large eggs
- 2 cups milk
- 1 teaspoon Dijon mustard
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon smoked paprika
- Salt and freshly ground black pepper, to taste
- 2 cups shredded sharp cheddar cheese
- 1 cup shredded mozzarella cheese
- 2 tablespoons chopped fresh parsley (optional, for garnish)
Instructions:
- Prepare the Bacon:
- In a large skillet over medium heat, cook the diced bacon until crispy.
- Using a slotted spoon, transfer the cooked bacon to a paper-towel-lined plate to drain excess fat.
- Prepare the Baking Dish:
- Lightly grease a 9×13-inch baking dish with butter or non-stick cooking spray.
- Assemble the Casserole:
- Spread the cubed brioche evenly in the bottom of the prepared baking dish.
- Evenly sprinkle the cooked bacon over the brioche cubes.
- In a medium bowl, whisk together the eggs, milk, Dijon mustard, garlic powder, onion powder, smoked paprika, salt, and black pepper until well combined.
- Pour the egg mixture evenly over the bacon and brioche layers in the baking dish.
- Sprinkle the shredded cheddar and mozzarella cheeses evenly over the top.
- Chill:
- Cover the baking dish with plastic wrap or aluminum foil and refrigerate for at least 4 hours, or overnight. This allows the bread to absorb the egg mixture fully.
- Bake:
- Preheat your oven to 350°F (175°C).
- Remove the casserole from the refrigerator and let it sit at room temperature for about 15 minutes.
- Bake uncovered for 45-50 minutes, or until the eggs are set and the cheese is melted and bubbly.
- If the top begins to brown too quickly, cover the casserole loosely with aluminum foil and continue baking until fully cooked.
- Serve:
- Let the casserole cool for about 10 minutes before slicing.
- Garnish with chopped fresh parsley, if desired.
- Slice into squares and serve warm.
Variations and Tips:
- Bread Options: While brioche provides a rich and slightly sweet flavor, you can substitute it with challah, French bread, or whole-grain bread, depending on your preference.
- Cheese Choices: Feel free to experiment with different cheese combinations, such as adding pepper jack for a spicy kick or using all cheddar for a more robust flavor.
- Vegetarian Adaptation: For a vegetarian version, omit the bacon and consider adding sautéed vegetables like mushrooms, spinach, or bell peppers.
- Make-Ahead Convenience: Preparing this casserole the night before not only enhances the flavors but also streamlines your morning routine, making it an excellent choice for holiday gatherings or busy weekends.
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat individual servings in the microwave or warm the entire casserole in the oven at 350°F (175°C) until heated through.
This Overnight Bacon Brunch Casserole combines the savory goodness of bacon and melted cheese with the comforting texture of baked brioche, all soaked in a flavorful egg custard.
