Overnight French Toast Casserole

With all of the crunchy goodness layered on top of a warm, fresh, sweet bread, this overnight French toast casserole could not be a better breakfast. This is the perfect make ahead morning dish for anything from a lazy Sunday morning or holiday brunch to Christmas morning or Mother’s day.

One of the great things about this overnight French toast bake is that you can prep it ahead and it’s ready the next morning. But you can also try it in a slow cooker — any way you slice it, it’s way easier than standing in front of the stove making individual slices of french toast.

The best of a classic French toast, stuffed french toast and casserole all in one.

Best for Make Ahead French Toast Casserole

Just like with bread pudding, I often use a good crusty French bread is best for making a French toast casserole overnight, but you can also use any leftover bread you have — even stale bread or just old bread (as long as it’s mold-free). Just make sure you are using the same amount of bread as listed in the recipe and slice the bread cubes the same way. Some of my favorites include:

• Challah
• Brioche
• Thick Cut White
• Honey Wheat

Why This Recipe Works

A breakfast casserole that you can prep ahead of time so allow you more time to spend with family on the holidays- what’s not to love!

• Make ahead – The best part is that you can make this breakfast bake ahead for holidays or a home-based brunch, then throw it in the oven.
• Perfect for Large Brunches – If you’re a holiday guest, bring this to satisfy sweet cravings. And if you are a host, this is an easy way to cut down on morning-prep.
• Not as Many Dishes – I rarely make traditional French toast because I hate the mess of all the dredging and skillet.
• Soaked with Flavor – I used to think that soaking bread overnight would be mushy and gross. I was WRONG. Turns out, that thick custard does a better job infusing the bread when it sits that long and makes the perfect texture.

Ingredients for Make-Ahead French Toast Casserole

Use these simple ingredients to make a delicious breakfast!

• Crusty French bread – Make sure to use the crunchiest of bread and cut it into 1-inch cubes. You can use sourdough bread, challah bread, brioche bread, french bread, italian bread, or any other kind of bread you choose.
• Eggs – Whisk eggs well and make sure that you choose large eggs.
• Whole milk – You’ll want the fat, so don’t skimp and use skim. Alternative milks can also be used.
• Heavy cream – Again, all of the fattiness will help make your casserole creamy.
• Granulated sugar – White sugar dissolves so quickly, which makes it perfect for this recipe. You can use all white sugar or all brown sugar, or a little of both as the recipe calls for.
• Light brown sugar – Pack your brown sugar to ensure you have just enough. Dark brown sugar is great if you really like the taste of molasses.
• Vanilla extract – Grab some from your cabinet or make your own! Other flavors can also be used- almond extract is another family favorite.
• Cinnamon – Adding ground cinnamon to this dish will round it out and give it flavor. Pumpkin pie spice or apple pie spice is fun during the holiday season.
• Sea salt – Make sure it’s fine so it mixes in and disperses easily and uniformly. Salt helps bring out the natural flavors and also balances the sweet elements. Sea salt is a direct salt with no iodine, resulting in better flavor.

Topping:

I happen to think the topping is the best part, but not everyone in my family agrees. I tend to double it, wink wink.

• Butter – Make sure your unsalted butter is melted to make it easy to mix.
• Light brown sugar –  Pack it tightly in the measuring cup to ensure to include the proper amount.
• Cinnamon – Use ground cinnamon to be able to sprinkle into this topping.
• Powdered sugar – Use a sifter or just pour the confectioners’ sugar into a small container to gently pour over the casserole when serving.
• Syrup – I prefer pure maple syrup, but use the syrup of your choice. Serve it at room temperature or warm it just slightly in the microwave before using.

How To Make Overnight French Toast – Step-By Step

This will be a huge hit for you (because you can do it the night before) and with your family. The perfect way to start the day.

1. Prepare bread. Cube the bread and place it into the baking dish in a single layer sprayed with cooking spray. Then, set aside.
2. Whisk custard ingredients. In a large bowl, whisk together the eggs, milk, heavy cream, sugar, brown sugar, vanilla, cinnamon, and salt. Ensure all ingredients are combined completely.
3. Add to bread. Slowly pour the egg mixture over the bread cubes in the casserole dish, making sure that everything is covered.
4. Press bread into pan. Using a large spoon, gently press the bread into the custard allowing it to soak up the mixture.
5. Cover and refrigerate. Cover the dish with aluminum foil or plastic wrap and refrigerate. Just before baking, bring the dish out of the refrigerator.
6. Make topping. Whisk together the melted butter, brown sugar, and cinnamon until smooth. Then, drizzle the sauce all over the top of the casserole.
7. Bake. Cover the pan with tin foil and bake. To allow the top to get crunchy, remove the foil halfway through and bake until golden brown.
8. Serve. Serve this dish with Dutch honey or maple syrup. Our cranberry or blueberry syrups are also great options. You can never go wrong with fresh berries. I also make it alongside my Cream Cheese Board with fresh bagels for savory craving folks.

Make it a Meal!

Because this is a sweet breakfast casserole, I like to serve it with savory options. Scrambled eggs, bacon in the oven, homemade breakfast sausage or hashbrown casserole are all great options. Of course, if you’re serving it for brunch, mimosas or an Orange Crush Cocktail would be a great addition too.

And don’t limit yourself to breakfast or brunch. You can surprise the kids and make breakfast for dinner too!

Variations

There are so many ways to make this easy eggy casserole your own. These are a fews of our favorites.

• Fresh fruits – Throw some fresh blueberries or other bright fruits on top.
• Substitute milks – If you don’t like or want to use regular milk, use your favorite alternative. Oat milk, coconut milk, almond milk or soy are great to experiment with. Homemade Eggnog is also a festive swap during the holidays.
• Zest – Using citrus, like orange zest, lemon, or lime, will add a brightness.
• Jam – Add dollops of your favorite jam to add some fruity flavor. 
• Nuts – Crush up some nuts and sprinkle them, for texture.
• Spices- Warm slices like grated nutmeg, pumpkin pie spice, or apple pie spice are a welcome addition to the custard mixture. 
• Dried fruit– Add some craisins or raisins or even dried bananas or mangoes to make this casserole fruity.
• Cream cheese – Add dollops of cream cheese to add extra decadence to this dish.

Storage and Freezing

Storage: Keep any leftovers covered with plastic wrap in the refrigerator for up to 3 days. For best results, reheat it in the oven at 350°F for 5 minutes. Microwaving bread can often make it rubbery.

Freezing: Freeze single servings in an airtight container for up to 3 months. You can even freeze the whole casserole. Check out our instructions here. After the casserole has cooked, allow it to cool fully and then place it in the freezer, uncovered, for about 12 hours. Remove it using the aluminum foil like a sling and then wrap it well in plastic wrap or freezer paper. Freeze for up to 6 months.

Reheating: To cook, unwrap and place it bake into the same baking dish (should fit like a glove). Bake for 40-45 minutes at 350°F or until it reaches an internal temperature of 155°F. Let it cool for 5-10 minutes before serving.
