Ingredients for Blueberry French Toast Casserole
- French Bread - or substitute sourdough bread, brioche or challah.
- Whole Milk - is the best for a creamy custard in this recipe.

- Light brown sugar
- Eggs
- Vanilla Extract - I recommend using pure vaniilla for best flavor. You could also substitute artificial if that is what you have on hand.
- Ground cinnamon
- Salt
- Butter
- Blueberries - you can use fresh or frozen blueberries. Fresh is best if in season and available.
- Pure Maple Syrup for serving
Variation - Streusel-Topped Blueberry French Toast Casserole
You can make a streusel crumble topping by combining 7 Tablespoons of cold butter, ⅓ cup light brown sugar, ⅓ cup of all purpose flour and ½ teaspoon of ground cinnamon.
With clean hands, fork or pastry blender, combine ingredients until you have a crumbly consistency.
Sprinkle the streusel on top of the casserole before baking.
How to Make Overnight French Toast Casserole
You can find a full printable recipe card if you scroll to the bottom of this page with a list of ingredients and step-by-step instructions.
STEP ONE - Cut the loaf of bread into slices and then cut each slice into thirds.
Place the bread chunks on a baking sheet for at least 8 hours or overnight so they dry out.
What Type of Bread Can I use?
You can use sourdough bread, brioche, or challah. Make sure the bread is very dry before baking. Bread that is too moist will result in a soggy casserole.
STEP TWO - In a large bowl, combine the whole milk, heavy cream, light brown sugar, eggs , vanilla, cinnamon and salt. Whisk for 2-3 minutes or until fully mixed. Set aside.
TIP: If you don't have time to dry the bread for 8 hours or overnight, you can place the bread in a preheated oven at 325°F for 10 minutes or until the bread is dried out. (not toasted and cruncy though!)
STEP THREE - Butter a 9x13-inch casserole dish on the bottom and the sides. Alternatively, you can spray with non-stick spray.
STEP FOUR - Transfer the stale bread to the baking dish.
STEP FIVE - Top the bread evenly with the fresh blueberries.
STEP SIX - Pour the egg custard (egg mixture) over the bread and blueberries into the baking dish, making sure all bread pieces are coated.
STEP SEVEN - Cover baking dish with plastic wrap and place in the fridge for 3 to 24 hours.
STEP EIGHT - Preheat the oven to 350°F and remove the baking dish from the fridge.
STEP NINE - Place baking dish in preheated oven and bake, uncovered for 45 to 55 minutes.
TIP - If the top starts to get too brown, tend the top of the baking dish with aluminum foil.
Allow casserole to rest for 5-10 minutes before serving. We love to serve our casserole with maple syrup and fresh blueberries.
How Do I Store the Leftovers?
You can store the leftovers in the fridge by placing aluminum foil or plastic wrap over the cooled baking dish for up to 3 days.
To reheat: Preheat oven to 350°F until heated through.
Make-Ahead Instructions
You can also freeze this dish without baking it. After you have all the ingredients in your air-tight container, you can freeze it for up to 2 months.
When ready to make, you will need to thaw overnight in the fridge, then bake according to the directions.
Serve with fresh fruit salad , maple syrup or easy homemade blueberry syrup. A sprinkled of powedered sugar adds sweetness and looks pretty on a plate as well.
