Tips & Variations

• Use sturdy bread like brioche or challah for a richer texture.
• Swap half the milk with heavy cream for extra creaminess.
• Add a handful of fresh berries or chopped nuts between the layers for added flavor and texture.
• For a dairy-free option, use almond or oat milk instead of dairy milk or cream.

Storage

Store any leftover casserole covered in the refrigerator for up to 3 days. Reheat portions in the microwave or oven until warmed through. This casserole does not freeze well due to the egg custard.

FAQs

Can I use a different type of bread?

Yes, thick-cut bread like brioche, challah, or Texas toast works best because it soaks up the custard without falling apart.

Can I prepare this casserole in the morning instead of overnight?

You can prepare and bake it immediately, but allowing it to soak overnight gives the bread time to fully absorb the custard, resulting in a more tender and flavorful dish.
