Overnight Blueberry French Toast Casserole

Introduction

Rich, bursting with berry flavor, and effortlessly elegant, this Overnight Blueberry French Toast Casserole is a breakfast you’ll want on repeat. Preparing everything the night before means that all you have to do in the morning is bake—and serve a comforting, make-ahead dish that tastes as if you spent all morning in the kitchen.

Whether you’re hosting brunch or need a stress-free holiday breakfast, this casserole delivers complex flavors and a custardy texture, highlighted by sweet, juicy blueberries and hints of warm cinnamon.

What Makes This Blueberry French Toast Casserole Special?

Unlike ordinary French toast, this casserole melds flavors overnight, softening cubes of bread into pillowy pockets surrounded by plump blueberries. A splash of vanilla, cream cheese dollops, and a drizzle of maple syrup add extra layers of decadence. Plus, you get all the crispy, golden-edged satisfaction of oven-baked French toast—while barely lifting a finger in the morning.

Key Prep Tips for the Best Casserole

Start by cubing a sturdy, slightly stale bread—brioche, challah, or French bread works best. Blueberries can go in fresh or frozen (no thawing needed). To achieve even cubes, try using the Mueller Pro-Series 10-in-1, 8 Blade Vegetable Chopper—it saves time and ensures an even bake.

When whisking the eggs and dairy mixture, blend until smooth and pour evenly over the layered bread and blueberries, making sure every piece soaks up the custard. For easy cleanup and perfect release, line your baking dish with Reynolds Kitchens Brown Parchment Paper Roll before assembling.

How to Assemble and Bake

The beauty of this recipe lies in its overnight preparation—simply assemble, cover, and chill. In the morning, bake until puffed and deeply golden. For those wanting to get a perfect, even egg-milk mixture, pulse it briefly in a Ninja BL610 Professional 72 Oz Countertop Blender before pouring over your casserole.

And if your oven mitts are worn, slipping hands into the KitchenAid Ribbed Soft Silicone Oven Mitt Set means removing your hot casserole with confidence.

Serving Ideas for Your Brunch Table

Cut the casserole into generous squares and serve with extra fresh blueberries, a drizzle of warm maple syrup, and a dusting of powdered sugar. Freshly whipped cream or a spoonful of lemon curd on the side turns this into a showstopping centerpiece for brunch. For gatherings, protect your table with a Pureegg Plastic Table Cloth Disposable 10 Pack—less mess, more ease.

Instructions

1. Lightly grease a 9×13-inch baking dish or line with Reynolds Kitchens Brown Parchment Paper Roll for easy removal.
2. Spread half of the bread cubes in the baking dish. Dot with half the cream cheese cubes and blueberries. Layer the remaining bread, cream cheese, and blueberries on top.
3. In a large bowl, whisk together eggs, milk, cream, sugar, maple syrup, vanilla, cinnamon, and salt until smooth. (For the smoothest custard, blend the mixture in a Ninja BL610 Professional 72 Oz Countertop Blender.)
4. Slowly pour the egg mixture over the bread, pressing lightly to ensure all pieces are moistened. Cover tightly and refrigerate overnight (or at least 4 hours).
5. When ready to bake, preheat oven to 350°F (175°C). Remove dish from fridge, uncover, and let sit at room temp while oven heats.
6. Bake uncovered for 45–55 minutes, or until the casserole is puffed up and golden brown. If the top browns too quickly, tent loosely with foil in the last 10 minutes.
7. Let cool for about 10 minutes before slicing. Serve warm with toppings of choice, and protect your serving area with a Pureegg Plastic Table Cloth Disposable 10 Pack for easy clean-up.
