Overnight French Toast Casserole With Crumb Topping Recipe

If you’re looking for an easy breakfast for company, this Overnight French Toast Casserole with crumb topping recipe is it. It’s a little sweet (more if you add maple syrup), the crumb topping steals the show, and it feeds a crowd. We use a La Brea Bakery French baguette in it, which absorbs the custard so well.

Having company is so much fun. The house is full, there are so many people to hang out with, and you get to catch up.

Cooking for company is less fun. It’s more work than you’re used to and you would rather be hanging out, catching up, than flipping dozens of pancakes.

And holiday breakfast is even more hectic because you don’t want to spend so much of the morning in the kitchen making breakfast and then so much of the rest of the day cooking dinner. That’s why this Easter, you need to make our Overnight French Toast Casserole With Crumb Topping.

You spend just a handful of minutes assembling it (cutting bread and making a custard that’s similar to what you use for bread pudding) then let it hang out in the fridge overnight. The next morning, you bake it in the oven for a little less than an hour. And that’s it.

This breakfast casserole uses really simple ingredients that you probably already have in your fridge. So, if you end up with unexpected guests this holiday, you can still whip up a batch.

How To Make An Overnight French Toast Casserole With Crumb Topping:

Cubed bread in a white bowl.

Cube the French baguette into 1-inch cubes. Put the bread in a large bowl and let it sit out for a couple hours until it starts to harden just a little.

Grease the bottom of a large casserole dish. I use butter, but you could use a non-stick cooking spray too.

Add the cubed bread.

White liquid and cinnamon in a white bowl.

In a large bowl, mix together the eggs, milk, heavy cream, vanilla, sugar, and cinnamon until its combined.

Stir everything with a large spoon until all the bread cubes are soaked.

Put the lid on top of the casserole pan and put it in the fridge overnight.

Cubes of butter, brown sugar, and flour in a bag.

Cut the butter into small cubes. Add it to a bag with the flour and brown sugar.

Mix the three ingredients together until all the ingredients are combined and a crumble topping starts to form.

You really want to make sure you incorporate all the butter into the mixture and not leave any butter chunks. This actually gets easier as you work it because the cold butter will warm up and incorporate easier.

Put the bag of crumble topping overnight in the fridge as well.

The next day, preheat the oven to 350 F and take everything out of the fridge.

Break apart any large chunks of crumble topping, leaving the small chunks as is. Pour the crumble topping on top of the casserole.

Bake for 55 minutes until the crumb topping is a golden brown color.

The bread will expand and the top of the casserole will inflate as it cooks. As it cools, that will fall back down.

Let the casserole cool for about five minutes before you scoop out individual servings.

We love adding a drizzle of pure maple syrup on top to add a little extra sweetness because this baked French toast casserole isn’t actually that sweet.

Overnight French Toast Casserole: Frequently Asked Questions

How do you store any leftover French Toast Casserole?

Wait until the casserole has cooled down to room temperature. Transfer it to an airtight container and keep it in the fridge for five to seven days.

How can you reheat French Toast Casserole?

Scoop a serving onto a microwave-safe plate and microwave it for 30 seconds, then add a drizzle of maple syrup.

Can you skip the crumb topping?

​Honestly, the brown sugar crumble topping is the best part of this casserole. It adds such a good texture to the recipe and it’s delicious. It’s the same crumb topping that I use for homemade coffee cake. And if you grew up in the Northeast, you know that classic flavor.

The French toast casserole isn’t that sweet and the crumb topping adds a sweetness, so it’s a really good balance. Without the crumb topping, the casserole will be a little underwhelming.

Do you have to cube the bread?

I had a boss who used to bring French toast casserole to every company potluck. It was delicious (and a flavor that I thought of when I made my own French toast casserole recipe). Instead of cubing the bread, she would cut it into slices, then put those slices in a casserole pan and pour her egg mixture on top.

It’s good that way. But when you serve it, you’re serving slices of French toast and need a knife and fork to eat it. With cubed bread, you can scoop it and eat it with a spoon. So that’s less utensils to wash after. And, it just makes this feel like a more fun, special occasions type of meal.

What kind of bread is best in French Toast Casserole?

Listen. The name is French toast. So I’m gonna really suggest a French baguette or French bread for this recipe.

If you can’t find those, a sourdough bread is a little more dense and would work. I wouldn’t suggest sandwich bread. That would be too soggy. If that’s the only type of bread all you have, then you want to leave it out overnight. Stale bread (or at the very least day-old bread) will help with the bread’s integrity.

More About La Brea Bakery:

La Brea Bakery is one of the largest artisan bread sellers in the United States. Look in the bakery section of your grocery store for the red, branded packages. This French baguette is fully cooked although there is a take and bake version, which means you would buy it in store and then finish baking it at home.

The La Brea Bakery French baguette is the best bread for this breakfast casserole because it’s soft, but still a crusty bread, so it can really absorb the custard mixture but won’t lose it’s shape or texture. If you choose a soft bread, the bread will turn to mush while it’s in the fridge overnight. You need something with a bit of integrity and the La Brea Bakery bread has that.

La Brea Bakery makes more than baguettes. It makes delicious loaves of bread, which you can get (sliced or whole) in your grocery store. We use La Brea Bakery New York Rye in our Corned Beef Grilled Cheese and it really does make such a difference in the sandwich.

This sounds yummy, and--like you--I am always up for some simplicity and time-saving tricks when it comes to either a special occasion (which is usually a lot of work anyway) and having company.
