How to Make the Best Blueberry Lemon Baked French Toast Casserole

This Blueberry Lemon Baked French Toast Casserole is a showstopper breakfast that’s perfect for feeding a crowd. With its beautiful layers of custardy bread, tart blueberries, and tangy lemon curd, it delivers impressive results with minimal effort. The make-ahead quality makes it ideal for busy mornings or special occasions.

Why You’ll Love This Recipe

The beauty of this casserole lies in its simplicity and flexibility. Unlike traditional French toast that requires cooking individual slices on the stovetop, this baked version lets you prepare it all in one dish and pop it in the oven. The combination of blueberries and lemon is both sophisticated and comforting—bright enough for summer breakfasts but cozy enough for fall gatherings. The crumble topping adds a delightful textural contrast to the custard-like interior.

Tips for Success

The key to a perfectly baked French toast casserole is choosing a sturdy bread like challah or brioche that can absorb the custard mixture without falling apart. Don’t skimp on the lemon zest—it’s what makes this recipe special and elevates it beyond a basic French toast bake. If you’re serving this for guests, assemble it the night before and refrigerate it covered. Simply bring it to room temperature before baking, or add a few extra minutes to the bake time if baking straight from the refrigerator.

Ingredients

French Toast Base

Crumble Topping

Instructions

Preparation

  1. Preheat the oven to 350°F. Spray a 9x13 pan with cooking spray or grease with butter.
  2. Cut the challah bread into bite-sized pieces using a bread knife or by hand tearing.

Assembly

  1. In a large bowl, whisk together the eggs, whole milk, heavy cream, brown sugar, granulated sugar, ground cinnamon, vanilla extract, and lemon zest.
  2. Add the pieces of bread to the french toast batter mixture and gently toss until all the pieces are coated. Mix in the blueberries.
  3. Transfer to the prepared baking dish.
  4. Dot the top of the french toast casserole with spoonfuls of lemon curd. Run a spoon, spatula, or knife through to swirl it in.

Topping & Baking

  1. Prepare the crumble topping. In a food processor, pulse the flour, sugar, and butter together. Alternatively, use a pastry cutter or your fingers to break the butter into pea-size pieces and mix with the flour and sugar.
  2. Sprinkle over the top of the prepared casserole. Optional: top with more blueberries.
  3. Bake at 350°F for 45 to 50 minutes. The center will be just a touch jiggly and the edges should be golden brown.
  4. Serve warm.

Notes

  • Any rich bread like challah, sourdough, or brioche works well in this recipe
  • You can use fresh or frozen blueberries
