Ingredients for Blueberry French Toast Casserole

• French Bread - or substitute sourdough bread, brioche or challah.

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.
