What kind of bread works best for Blueberry French Toast Casserole?

The best bread choices are brioche or challah since they soak up the custard without getting mushy. Day-old bread works well because it holds its structure and gives the casserole a balanced texture.

Can I use frozen blueberries instead of fresh?

Yes, frozen blueberries work perfectly. Add them straight from the freezer without thawing. They release a bit more juice, which adds extra flavor to the casserole.

How do I keep my French toast casserole from getting soggy?

Use sturdy bread, avoid cutting cubes too small, and let the casserole rest overnight to soak evenly. Baking until the center is fully set also prevents a soggy texture.

Can I make this casserole ahead of time?

Yes, this recipe is ideal for making ahead. Assemble it the night before and refrigerate until morning. You can also freeze the unbaked casserole and bake it later.
