French toast casserole is the perfect make-ahead breakfast. Add some fresh or frozen mixed berries for an even tastier meal.
Jump to RecipeBig Breakfast Sunday at our house has me trying to find new ideas for breakfast. We all enjoyed French Toast Casserole in the past, so I decided to add to that this time. We had some frozen berries and bananas that needed to be used.
I love having make-ahead meals for the weekends. It makes Sunday morning so easy for us so we can relax. This casserole is prepared at night and all you have to do in the morning is put it in the oven and bake.
Make sure you place the casserole in a COLD oven. You don’t want to put a cold glass dish in a hot oven because it could shatter. Yes, I’ve done that before. I had to buy a new pan, we had to make a new meal, and I had to clean the broken glass and food from the oven.

Berry French Toast Casserole Step by Step
Ingredients
- 14 oz French bread, cut into 1-inch cubes
- 1 banana, overripe
- 1 cup almond milk
- 3 eggs
- 3 egg whites
- 2 tbsp maple syrup
- 1 tbsp vanilla extract
- 2 tsp ground cinnamon
- 6 oz frozen mixed berries
- 2 tbsp brown sugar
- 2 tbsp vegan butter

Preparation
Arrange bread cubes in a 9×13 casserole dish coated with cooking spray.

In a medium bowl, mash the banana with a fork then whisk in the milk, eggs, egg whites, maple syrup, vanilla, and cinnamon until combined.

Pour the mixture over the bread crumbs, coating as many as possible, tossing to coat if needed.

Sprinkle the berries over the bread.

Cover and chill in the refrigerator for at least 6 hours, up to overnight.
When ready to bake, combine the butter and brown sugar in a bowl until it forms a paste.
Remove foil from the casserole dish and put dollops of the brown sugar mixture around the casserole.

Cover again and place in a cold oven.
Set the temperature to 375F and bake for 35 minutes.
Remove the foil and bake another 10 minutes, until golden brown.

Leftovers
In my opinion, this is best served fresh and doesn’t keep very well. Because of it being a make-ahead meal, it’s already cooled and heated once. I don’t suggest doing that again. If you know you won’t eat it all in one sitting, then break it up into two smaller casserole dishes to only heat the portion you will eat.

Berry French Toast Casserole FAQs
Yes, you can also use fresh berries in this recipe.
No, you can use any milk and butter. We just choose not to have dairy so use those in their place.
When you put a cold dish into a hot oven, there’s a chance that the drastic change in temperature can shatter the dish, especially if it’s glass. By letting the oven heat around it, the dish is slowly brought up to temperature.
