Ingredients

French Bread – 1 loaf
Whole Milk – is the best for a creamy custard in this recipe.
Heavy Cream
Brown Sugar – I used a light brown sugar
Eggs
Vanilla Extract – I like to use pure vanilla extract for the best flavor, you could also substitute with artificial if that is what you have on hand
Cinnamon – ground cinnamon
Salt
Butter
Blueberries – you can use fresh or frozen blueberries, I like to use fresh blueberries if in season and available
Maple Syrup – pure maple syrup is best for serving

Substitutions

In place of heavy cream you can use whole milk but the casserole will not be as rich. You can use less brown sugar if you do not like it as sweet.

French Toast Casserole Streusel Topping Variation

You can make a streusel crumble topping by combining 7 Tablespoons of cold butter, 1/3 cup light brown sugar, 1/3 cup of all purpose flour and 1/2 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.

What type of bread can I use?

You can use sourdough bread, brioche, or challah. Make sure the bread is very dry before baking. If the bread is too moist it will result in a soggy casserole!!

How To Make Blueberry French Toast Casserole Recipe

Sliced bread cubes on wooden cutting board with a knife.

Pro 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 crunchy though!)

Bread cubes are placed in the bottom of 9c13-inch baking dish.

STEP THREE – Butter a 9×13-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.

Fresh blueberries are placed on top of the bread and custard mixture in baking dish.

STEP FIVE – Top the bread evenly with the fresh blueberries.

Custard mixture is poured on top of the bread and blueberry mixture in baking dish.

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.

Allow casserole to rest for 5-10 minutes before serving. We love to serve our casserole with maple syrup and fresh blueberries. Enjoy!

Sandra’s Top Tips

If the top starts to get too brown, tent the top of the baking dish with aluminum foil
When you store any leftovers they can become soggy, reheating it in the oven will help it to not be soggy
Serve with fresh fruit salad, maple syrup, whipped cream or easy homemade blueberry syrup. A sprinkled of powedered sugar adds sweetness and looks pretty on a plate as well.
