This Overnight Blueberry French Toast Casserole is a favourite dish for special holiday breakfasts. I think everyone loves french toast, and this french toast casserole is almost like a bread pudding. Except, that it isn't.
What I would call this overnight blueberry french toast breakfast casserole, is a sweet strata. A strata is a brunch dish consisting of layers of bread, egg, and cheese. This breakfast dish is skipping the cheese, and instead of using blueberries, cream and maple syrup.
Make-Ahead Makes For an Easy Celebration Morning
French toast baked into a casserole is almost pudding-like, though. You still get the browned, slightly crisp topping, and the delicious spongy, eggy baked bread filling. Soaking sourdough bread in eggs, cream and sugar is super easy to do the night before, all in one casserole dish. Put it in the fridge, and then you just pop into the oven in the morning. Which is nice for everyone, most especially, the cook. If that happens to be you, (and I'm thinking it is, since you're here, looking at this recipe for a make-ahead breakfast), you deserve a break on that special morning, too.
A Celebration Treat Breakfast
Right off the bat, I'll be clear. This recipe is unapologetic about being not: gluten-free, dairy-free; sugar-free, vegan, low fat, low carb, low calorie, or low anything. This delicious french toast recipe is basically dessert for breakfast. It isn't a healthy, nutrient-packed breakfast. My normal is all about making healthy, nutrient-packed food choices. That's my every day, and I'm sure it's probably yours too.
With All The Good Stuff That We Hate To Love
This make-ahead breakfast casserole is bread soaked in eggs, cream and sugar. But, this baked french toast is a festive and yummy treat for a special occasion morning. It's a perfect Christmas or Easter morning treat.
I'm using local blueberries in this recipe, because thanks to this summer's bounty, that's what I have in my freezer. But you can change up the berries according to the season, use strawberries in the spring, raspberries or blackberries in mid-summer, or tropical fruit, (try mango and/or pineapple, and sprinkle shredded coconut over top), in the winter. If, however, you have blueberries on the mind, like me, you may want to check out Banana Blueberry Spelt Muffins, Finnish Blueberry Pie, or Rhubarb Blueberry Oatmeal Bars.
And, here's another delicious make-ahead recipe to try: Baked Breakfast Egg Cups

Love that you have added nutmeg too in your French toast blueberry casserole! It's such an underrated spice and doesn't make a common appearance in sweet desserts. Getting hungry now! 😀
Colleen
Hi Helene. The nutmeg adds a perfect touch to this dish. 🙂

Goodness! This Blueberry French Toast Casserole looks amazing, Colleen. I love the indulgence of making a recipe like this for Christmas morning and looking forward to it all year long, don't you? Thank you for sharing! Merry Christmas to you as well!

Nicoletta @sugarlovespices
We're hosting a Christmas brunch at our place with the kids and their partners. This would be perfect! Make it the night before, just pop it in the oven in the morning and serve it hot to our family. We have so many local berries in our freezer: sour cherries, haskaps, saskatoons, and BC blueberries. I'm thinking also a combination of berries would work well. Thanks for the idea!
Colleen
Nicoletta, this is perfect for a brunch, and a great way to use up those berries in the freezer, too.
Elaine @ Flavour and Savour
This is on the menu for Christmas Eve brunch! I'll be using a mix of blueberries, raspberries and blackberries. Happy holidays, Colleen!
Colleen
Elaine, that sounds like a delicious mix of berries for this. Enjoy, and Merry Christmas.
Dina
