Quick Overview
What’s the best way to make custard? Is it safe to bake blueberries in a pan? Is it easy to soak bread overnight? Is it worth the wait to try this custardy treat?
Ingredients
For the Main Batter:
* 1 loaf of brioche or challah bread, cut into 1-inch cubes (Brioche is my go-to because it’s rich and buttery, but challah works great too! Make sure it’s slightly stale – it soaks up the custard better.)
* 6 large eggs (Use good quality eggs – they make a difference in the richness of the custard.)
* 2 cups milk (I’ve tested this with almond milk and it actually made it even creamier! Regular milk works just as well, though.)
* 1 cup heavy cream (Don’t skimp on the heavy cream – it adds so much richness and flavor!)
* 1/2 cup granulated sugar (You can adjust this to your liking – I like mine on the sweeter side.)
* 2 teaspoons vanilla extract (Pure vanilla extract is a must – it adds a wonderful aroma and flavor.)
* 1/4 teaspoon salt (A little salt balances out the sweetness and enhances the other flavors.)
For the Filling:
* 2 cups fresh blueberries (Fresh is best, but frozen blueberries work in a pinch! Just make sure to thaw and drain them before using.)
* 2 tablespoons granulated sugar (This helps to sweeten the blueberries and create a nice syrupy sauce as they bake.)
* 1 tablespoon lemon juice (The lemon juice brightens up the blueberries and adds a touch of tanginess.)
For the Glaze:
* 1 cup powdered sugar (Sift it to avoid any lumps in your glaze. ) * 2-3 tablespoons milk (Add the milk gradually until you reach your desired consistency. * 1/2 teaspoon vanilla extract (This adds a nice touch of flavor to the glaze.)
What are the steps to
Step 1: Preheat & Prep Pan
Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or cooking spray. I always use butter for flavor! What should I do if my casserole is sticking to the pan?
Step 2: Mix Dry Ingredients
In a large bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla extract, and salt until smooth. Set aside. What do you like about custard? When the sugar is fully dissolved, it is not able to be absorbed.
Step 3: Prepare Filling
In a separate bowl, toss the blueberries with the sugar and lemon juice. Set aside. How do you make blueberry sauce? How do you crush blueberries?
Step 4: Assemble the Casserole
Place the bread cubes in the prepared baking dish. Pour the egg mixture evenly over the bread, making sure to soak all the pieces. Gently press down on the bread to help it absorb the liquid. Do not over-do the blueberry mixture on bread. At this point, you can cover the dish and refrigerate it overnight, or bake it immediately. I always prefer to let it soak overnight – it really enhances the flavor and texture!
Step 5: Bake
Is it safe to bake custard in the preheated oven for 45-50 minutes? Is there a knife that comes out clean? If the top is browning too quickly, you can tent it with foil. Every oven is different so keep an eye on it! I usually start checking around 40 minutes.
Step 6: Cool & Glaze
Let the casserole cool before glazing. While it’s cooling, whisk together the powdered sugar, milk, and vanilla extract until smooth. How do I drizzle glaze over a casserole? How do I adjust the consistency of the glaze by adding more or less milk? I like mine on the thicker side!
Step 7: Slice & Serve
How do you slice a blueberry french toast into squares and serve warm? I like to sprinkle it with powdered sugar or drizzle with maple syrup for an extra touch of sweetness. I also like a little extra cinnamon. What is the touch of sweetness? What are some great side dishes to serve with whipped cream?

The top should be golden brown and the custard should set.Glaze Consistency: Adjust the consistency of the glaze to your liking by adding more or less milk. I like mine on the thicker side, but you can make it thinner if you prefer. For a bolder flavor, you can even use lemon juice instead of milk in the glaze.
Ingredient Swaps: Feel free to experiment with different ingredients!

Storing and Reheating Tips
This Blueberry French Toast Casserole is best enjoyed fresh, but it can also be stored and reheated for later.
Room Temperature: You can leave it at room temperature for a few hours.
Refrigerator Storage: Store the casserole in an airtight container in the refrigerator for up to 3 days. Make sure it’s completely cooled before storing it.
Freezer Instructions: For longer storage, you can freeze the casserole. Wrap it tightly in plastic wrap and then in foil. Freeze for up to 2 months. Thaw it overnight in the refrigerator before reheating. I don’t recommend freezing the glaze, as it can become watery.
Glaze Timing Advice: If you’re planning to store the casserole, it’s best to wait to add the glaze until just before serving. This will prevent the glaze from becoming soggy.
Reheating Instructions: To reheat, bake the casserole in a preheated oven at 350°F (175°C) until heated through. You can also microwave individual slices for a quick and easy breakfast or snack. When reheating from frozen, bake it covered with foil until it’s heated through then remove the foil to let it brown.
