How Do You Keep French Toast Casserole From Getting Soggy?
To prevent French toast casserole from getting soggy, use stale or day-old bread, cut it into cubes and let it sit out for a few hours or overnight to dry out. Then, whisk together the custard ingredients (eggs, milk, sugar, and vanilla) and pour it over the bread cubes, making sure to coat each piece evenly. Finally, bake the casserole until it is golden brown and set, and let it cool for a few minutes before serving. This will help the custard absorb into the bread without making it too soggy.
