About This Baked French Toast
I don't always make these types of dishes but for special occasions like the holidays, this baked French toast casserole is what I turn to for breakfast.
Oven-baked French toast is just so delicious. Condensed milk is so delicious. And when you combine them, it is pure heaven.
This recipe is a make-ahead recipe that is assembled the night before and baked in the oven the next morning. I love this because it allows me to make a special breakfast in the morning without all of the hassle.
It is also no secret to people who know me that I love sweetened condensed milk. To me, it is an easy way to dress up any sweet dish and a time saver in the kitchen.
I use it as the base for my vanilla condensed milk sauce. It also plays a starring role in my mini crustless pumpkin pie and lemon bars.
Let me show you how wonderful working with condensed milk is and how to make the best baked French toast with it.
What You Will Need
The ingredients are really simple for this baked French toast. The only extra player in this mix that you wouldn't find in a regular French toast is the sweetened condensed milk.
- Thick stale bread: I love using thick sliced country bread for this recipe.
- Eggs: Large eggs work best here.
- Sweetened Condensed milk: The star of this baked French toast recipe!
- Milk: This helps thin the condensed milk a bit.
- Vanilla: I like to use vanilla extract but vanilla paste or pods work well.
- Cinnamon: French toast and cinnamon are the perfect match.
- Butter: Unsalted is perfect.
- Salt.
- Walnuts and fresh raspberries (optional but recommended): These are my favorites for topping the French toast. You could also just use maple syrup or whipped cream!

How To Make
This baked condensed milk French toast is really a special breakfast and perfect for anyone looking for new breakfast ideas. It is also so easy to make. Here is what you do (full recipe below):
- Make the custard: Mix (whisk) the eggs, milk, condensed milk and spices in a large bowl.
- Layer bread in a buttered baking dish: Butter a baking dish so the bread does not stick then layer the bread slices on top of each other in the baking dish.
- Pour custard over the top: Pour the custard over the top making sure to get all of the bread.
- Refrigerate: Place the unbaked French toast in the fridge overnight. This allows the bread time to soak up the custard.
- Bake: Once the French toast has had time to rest, bake it in a pre-heated 350-degree oven for about an hour.
Storing
If you have leftover French toast, you can store it in an air-tight container in the fridge for up to 3 days. To reheat it, place it on a plate and microwave on medium heat for 1 minute.
Recipe Faqs
If you do not have milk, evaporated milk or condensed milk that is thinned out make a good substitute.
If your French toast is soggy, it needs more time to bake to allow the surface of the French toast to crisp up and the liquids to slightly evaporate.

I made a 13x9, so I increased the number of eggs to nine and added an extra half cup of milk. I also doubled the vanilla and cinnamon and added the zest of one large orange. Finally, I spread all the pieces of bread with softened cream cheese (one full brick) before pouring the custard mixture over the top. It was so good that it did not even need any toppings or any additional sweetener. Thanks for the recipe!
