This is a nice make ahead breakfast casserole. It combines french toast ingredients with blueberries that are just delightful. I like to serve it drizzled with my blueberry sauce and sprinkled with a little powdered sugar.

Traditional French bread is sliced and fried quickly on the stovetop to create a contrasting dry crumb and buttery surface, but baked breakfast casseroles rely on prolonged liquid absorption to build their structure. Stale bread functions like a sponge, drinking up the dairy and egg mixture without dissolving into mush during the resting phase. Allowing the assembled casserole to sit in the refrigerator for at least six hours gives the starch molecules adequate time to fully hydrate before the pan goes into the 350 degree Fahrenheit oven. Skipping this hydration window results in a crumbly interior rather than the cohesive, custard-like crumb that defines this baked style. Covering the baking dish with foil for the initial thirty minutes of cooking traps steam to gently set the interior eggs without scorching the exterior, while removing the cover for the final thirty to thirty-five minutes allows the top to develop a golden crust. Meanwhile, managing starch gelatinization requires careful temperature control when preparing the separate fruit topping. Whisking cornstarch into the cold water and sugar mixture prevents lumps before heat is applied, and simmering the liquid until the berries burst releases natural pectins that thicken the sauce without flour. For home cooks needing dietary modifications, dairy milk can be replaced with canned coconut milk at a one-to-one ratio without altering the structural integrity of the soaked bread. Resting the baked dish for ten minutes before slicing ensures the internal steam pressure drops, allowing clean portions to be transferred to plates without collapsing.
