How to Make Overnight Breakfast Casserole
Cube the Bread: Start by cutting your thick sliced bread into cubes. For the best texture, allow them to sit out overnight or dry them slightly in the oven at 300°F for about 10 minutes—just don’t brown or toast them!
Whisk the Custard: In a large bowl, whisk together the eggs, milk, dry mustard powder, salt, and black pepper until smooth. This rich custard is the heart of your casserole and binds all the flavors together beautifully.
Layer the Ingredients: Grease a 9×13 baking dish, then layer half of the cubed bread in it. Follow with half of the cooked bacon, sliced green onions, diced red bell pepper, and shredded cheddar cheese. Repeat these layers for a flavor-packed casserole!
Pour the Custard: Carefully pour the egg custard mixture over the top of the layered casserole, ensuring all the bread cubes are evenly moistened. Cover it and place it in the refrigerator for at least 3 hours, or ideally, overnight.
Preheat and Rest: Once ready to bake, take the casserole out of the fridge and let it sit at room temperature while preheating your oven to 350°F. This helps it bake evenly and thoroughly.
Bake to Perfection: Cover your casserole with foil and bake for 45 to 55 minutes, or until a knife inserted in the center comes out clean. If you’re doubling the recipe and using two pans, expect to increase baking time to 60-80 minutes.
Optional: Serve with a sprinkle of fresh chives or parsley for an extra touch of flavor!

Expert Tips for Overnight Egg Casserole
Bread Choice: Use thick, sturdy bread like sourdough or brioche. Avoid thin or sliced bread to prevent mushiness in your overnight egg casserole.
Dairy Variations: For richer flavor, use whole milk or even half-and-half. This makes the custard creamier and more luscious!
Layering Technique: Ensure an even distribution when layering ingredients. This adds consistent flavor throughout and prevents clumping.
Chill Time: Don’t skip the refrigeration! Allowing the casserole to sit overnight helps the bread fully absorb flavors, resulting in a more cohesive dish.
Test for Doneness: If unsure about doneness, perform the knife test! Insert a knife in the center; it should come out clean when fully cooked.
Customize Away: Feel free to mix in your family’s favorite ingredients—swap out bacon for sausage, or add spinach and mushrooms for a veggie boost!
How to Store and Freeze Overnight Egg Casserole
Fridge: Store leftover casserole in an airtight container for up to 3 days. Reheat individual portions in the microwave or bake in the oven at 350°F until warmed through.
Freezer: For longer storage, freeze the casserole before baking for up to 2 months. Thaw overnight in the fridge and bake as directed.
Reheating: After thawing, cover with foil in a preheated oven at 350°F and bake until heated thoroughly, about 30-40 minutes.
