Blueberry French Toast Casserole is a make-ahead breakfast that feels special without being fussy. Cubed bread, pockets of cream cheese, and bursts of blueberries bake into a soft, custardy casserole that’s finished with a warm blueberry sauce.
This is the kind of breakfast that’s perfect for holidays, brunch gatherings, or anytime you want to prep ahead and serve something comforting and generous.
Meggan’s Notes
This casserole is designed to be assembled the night before, giving the bread plenty of time to soak up the custard so it bakes evenly and stays tender throughout. Cream cheese melts into the casserole as it bakes, creating rich pockets that balance the fruit.
The blueberry sauce is cooked separately and spooned over the finished casserole just before serving. It adds brightness and keeps the casserole from becoming overly sweet or heavy. Together, the textures and flavors feel familiar, balanced, and worth gathering around the table for.
Why This Recipe Works
- Overnight soak: Ensures a soft, custardy interior.
- Cream cheese pieces: Create rich pockets throughout the casserole.
- Separate sauce: Adds freshness and prevents sogginess.
- Make-ahead friendly: Ideal for stress-free mornings.
Blueberry French Toast Casserole Ingredients
At a Glance: Here is a quick snapshot of what ingredients are in this recipe.
Please see the recipe card below for specific quantities.
- An overnight soak improves texture: The bread has time to absorb the custard fully, which helps the casserole bake up soft and evenly custardy.
- Cream cheese adds rich contrast: As it bakes, the cream cheese melts into tender pockets that balance the fruit.
- A separate blueberry sauce keeps things balanced: Spoon it over just before serving for brightness, sweetness, and a fresher texture.
- Make-ahead prep keeps mornings easy: Assemble it the night before, then bake and serve with very little hands-on work.
How to Make Blueberry French Toast Casserole
- Coat a 9-inch by 13-inch baking dish with nonstick spray. Spread half the bread cubes in the bottom of the dish. Add the cream cheese in pieces evenly over the bread.
- Top with 1 cup blueberries and remaining bread.
- In a large bowl, beat eggs. Beat in half-and-half, maple syrup, and vanilla until smooth. Pour over the casserole. Cover with foil and chill at least 8 hours or overnight. Remove from the refrigerator at least 30 minutes, or up to 1 hour, before baking.
- Adjust an oven rack to the middle position and preheat oven to 350 degrees. Bake covered for 45 minutes. Remove foil and bake until golden brown and set in the middle, about 10 minutes longer.
- Meanwhile, in a medium saucepan over medium-high heat, whisk together water, sugar, and cornstarch. Bring to a boil, reduce the heat to medium, and cook for 3 minutes, stirring constantly.
- Stir in blueberries and simmer until the berries burst, about 8 to 10 minutes. Stir in butter until melted.
- Pour sauce over the casserole.
- For best results, let casserole rest at least 10 minutes before slicing.
Blueberry French Toast Casserole Tips and Variations
- Yield: This recipe makes about 12 cups of casserole, a full 9-inch by 13-inch baking dish.
- Make ahead: Assemble the casserole up to 24 hours in advance.
- Bread options: Brioche, challah, or Hawaiian sweet rolls all work well. I’ve made this recipe with Texas toast, too, and you’ll need to add more liquid (an extra ½ cup milk or half and half, at least).
- Extra crunch: Sprinkle sliced almonds or streusel on top before baking.
How to Store Blueberry French Toast Casserole
- Refrigerator: Store leftovers covered for up to 4 days.
- Reheating: Warm individual portions in the microwave or oven.
- Sauce: Store separately and reheat gently to 165 degrees.

Notes
- Bread: I use a soft sandwich bread in this recipe. If you use more than 12 slices, you won’t have enough liquid to moisten the casserole properly. Dry the bread up to 3 days in advance on the counter (keep it covered with a dry kitchen towel) or cube and dry in a 300-degree oven for 30 minutes.
- Blueberries: Either fresh or frozen blueberries work in this recipe. I use frozen berries because they are more convenient and economical.
