Let’s walk through how to make this overnight French toast casserole, what ingredients you need, how to customize it, and what to serve with it for the perfect breakfast spread.
Ingredients Needed
You do not need any special tools or ingredients for this recipe. It is built from simple, everyday staples that you probably already have in your kitchen. The key ingredient is bread. Thick, slightly stale bread works best because it soaks up the custard without falling apart. Brioche and challah are favorites because of their rich texture and subtle sweetness. If you only have regular sandwich bread, that will work too, but the texture may be a little softer.
Here is a detailed look at everything you will need.

Step-by-Step Cooking Instructions
Start by preparing your baking dish. Lightly grease a 9 by 13 inch casserole dish with butter. This helps prevent sticking and adds a little flavor.
Next, cube your bread into bite-sized pieces. If it is fresh, you can leave it out for an hour or two to dry out a bit. Place the bread cubes evenly in the greased dish. Try to make sure they are spread out so the custard soaks into every piece.
In a large bowl, crack the eggs and whisk until fully combined. Pour in the milk, cream, sugars, vanilla, cinnamon, nutmeg, and salt. Whisk again until smooth. You want a rich, creamy mixture that will soak into the bread overnight.
Pour the custard evenly over the bread cubes. Use a spatula or the back of a spoon to gently press the bread down into the liquid. This helps it absorb all the goodness. Cover the dish tightly with plastic wrap or foil and refrigerate overnight. Let it sit for at least 8 hours, but you can leave it up to 24.
In the morning, preheat your oven to 350 degrees Fahrenheit. Take the casserole out of the fridge and let it sit on the counter while the oven heats up. This takes the chill off and helps it bake more evenly. Dot the top with small pieces of butter for extra flavor and browning.
Bake uncovered for 45 to 50 minutes. The top should be golden and slightly crisp, and the center should be set but still soft. Let it rest for 10 minutes before serving. The texture will firm up a bit as it cools.
Tips for Customizing the Recipe
This casserole is easy to adjust based on what you have or what you are craving.
Use different types of bread if you want to experiment. Sourdough adds a tangy flavor while croissants make it extra buttery. Add sliced bananas, blueberries, or raspberries before baking to bring in some natural sweetness and color.
A swirl of cream cheese or dollops of mascarpone makes it taste like cheesecake in breakfast form. For a little crunch, sprinkle chopped pecans or walnuts on top before baking.
If you need a dairy-free version, swap the milk and cream for almond milk or coconut milk. You can even use a dairy-free butter alternative. The results are still rich and satisfying.
Want something indulgent? Add chocolate chips, caramel drizzle, or crushed graham crackers. The options are endless, and this recipe is hard to mess up.
