French Toast Casserole Ingredients
Brunch is without a doubt my favorite meal. Basically because you get the best of both worlds: savory and sweet. This baked berry French toast delivers heavily on the sweet. We will need:
- French bread – or challah or sourdough are also recommended. Ideally, you want the bread to be about a day old. You can also cut the bread into slices and let sit out overnight, or toast the bread in the oven to speed up the drying process.
- fresh berries – I used a triple berry mix of blueberries, raspberries and strawberries for extra berry goodness.
- whole eggs – you can’t really do french toast without eggs!
- egg whites – using egg whites lightens this recipe up a bit.
- maple syrup – provides some sweetness to the casserole without adding refined sugar.
- non-dairy milk – I used oat milk here, making this recipe dairy free and nut free. But feel free to use your favorite (dairy or not). Adding in some canned coconut milk or half and half will provide a richer texture as well.
- vanilla extract – an exquisite flavor boost – make sure not to skip it!
- toppings – French toast wouldn’t be complete without warm maple syrup and whipped cream. If you want to get really indulgent, turn it into a French toast casserole with cream cheese (directions in recipe card below)!
Berry Tip: If you’re looking for just two berries to use in this french toast bake, my recommendation would be to go with blueberries and raspberries . The combination of those two berry flavors together is really delicious! Plus, less prep (no slicing necessary) and the blueberries especially hold up well when baking.

How to Make
Making this baked berry French toast casserole is pretty simple. The main part of making this recipe is preparing the bread, and also deciding which route you want to go – making sure to plan enough time to allow the bread to dry out OR toasting the bread just slightly to dry it out. Here’s how to do it:
Prep Bread
Slice day-old, dry bread into 1″ cubes. Place bread in the bottom of a greased 9×13 inch casserole dish.
Add the berries, leaving a few to the side to top with at the end (or simply add more to top).
Make Custard
In a large bowl, whisk together eggs, egg whites, maple syrup, milk and vanilla extract until combined.
Combine Casserole
Pour the egg mixture over top of the bread in the casserole dish, making sure to press the bread down so that all of the pieces have been soaked. Add more berries to the top, filling in any holes you see.
Cover and Refrigerate
Cover and refrigerate for at least 2 hours. If you’ve dried out your bread, you can soak the bread for up to 8 hours (overnight).
Bake
Set the casserole out on the kitchen counter for 30 minutes before baking. Preheat oven to 350ºF.
Bake uncovered for 30 minutes, then cover with foil and bake an additional 15-20 minutes (the foil keeps the top from browning too much).
Allow the French toast bake to rest for 15 minutes before serving. Once the casserole is ready, sprinkle with powdered sugar if you’d like. Serve warm with maple syrup and / or whipped cream.
Serving Suggestions
Nothing says celebratory meal more than a baked French toast with berries. I love to serve this as:
- Weekend Brunch: Serve a crowd of family and friends with this scrumptious fruit French toast casserole. Whether you are hosting your own brunch, or going to a friend’s house, this one is sure to please.
- Breakfast: Prep and bake it over the weekend, then cut into small squares and enjoy as an indulgent breakfast for the next few days.
- Holidays: Serve this beauty on Easter, Mother’s Day, Memorial Day Weekend, or Father’s Day, or any time the occasion calls for it!
How to Store & Reheat
Berry baked French toast is best enjoyed the day it is made, but leftovers can be stored, tightly covered with plastic wrap, in the fridge for 1-2 days.
Reheating Instructions: Pop a square in the microwave, in 30-second increments to prevent scorching, until warmed through.
Overnight Berry French Toast Casserole
If you’re looking to make prepare this french toast casserole overnight, I’ve got you covered.
All prep remains the same, simply cover tightly with plastic wrap and leave in the fridge overnight. When you wake up in the morning, remove from the fridge at least 30 minutes prior to baking.
TIP: The overnight soak is best for bread that is stale and at least one day old, or has been dried out in the oven. Dry bread allows the casserole to hold it’s structure, without becoming too soggy.
Frequently Asked Questions
Yes! Substitute an equal amount of frozen berries when fresh fruit is not in season.
The bread was not dry enough or there was too much egg mixture. Cover with foil and bake an additional 5-10 minutes to evaporate some of the moisture.
Leftover berry French toast bake can be reheated in 30-second increments in the microwave.
I haven’t tested this with gluten-free bread but I imagine if you can find a similar loaf style to French bread that is gluten-free, then the recipe would work.
Yes! I used oat milk in this recipe but you can use soy, cashew, almond or coconut (or a blend). You can also use traditional cow’s milk.
If you’d prefer to stick with one berry, I’d say go with blueberries. You may only need about 2 cups total.

We swapped our regular baked french toast recipe for this one and loved it! We let it hang in the fridge overnight and it baked up perfectly. The addition of the berries throughout are so good. Didn’t try the cream cheese, but will next time!

I made this for Christmas and it was a big hit! It was delicious, not too sweet, and the berries were the perfect touch. I added a little cinnamon to the egg mixture and it worked great! I’ll be making this again!
