Ingredient notes and substitutions
- Bread: If you can’t find cottage bread, choose another thick, sturdy type of white bread for this recipe. Texas toast or thick-sliced white breads like artisan sandwich bread would be the best substitute.
- If you’re using an airier bread, like regular white sandwich bread, I recommend decreasing the number of eggs and only using 8 and decreasing the amount of milk to 2 ½ cups.
- Milk: You can use any milk, from skim milk to whole milk, in this recipe. Heavy cream or half-and-half can also be for part of the milk. Plant-based milk, like almond milk, can also be used in this recipe.
- Maple syrup: If you don’t have pure maple syrup, you can use brown sugar.
- Butter: I use salted butter. If you’re using unsalted butter, add a small pinch of salt with the butter.

Recipe Tips!
- Brown sugar topping: Feel free to omit the topping. You can also double the topping amount if you want more caramelized sugar topping.
- Serving suggestions: This easy overnight French toast casserole is always a huge hit at my house. I like to serve this baked French toast casserole with fresh fruit and sausage or bacon. The casserole can be topped with a number of different toppings. Here are some ideas:
- Maple syrup
- Other flavored syrups like strawberry sauce or buttermilk syrup
- Powdered sugar and sliced strawberries
- Whipped cream and fresh berries
Recipe FAQs
Cottage white bread is a dense white sandwich bread. The bread is thicker and sturdier than traditional white bread, which makes it ideal for use in French toast.
I recommend chilling the French toast casserole for at least 4 hours. The overnight soak gives the bread time to absorb the egg mixture before baking.
Storage
Store any leftover French toast casserole in an airtight container in the refrigerator. The French toast will keep for up to 3 days when properly stored in the fridge.

Hi, for the brown sugar in place of the maple syrup do we use the same measurement of 1/4 cup?
