How to Make Overnight French Toast Casserole
-
Butter the Dish: Start by generously greasing your baking dish with 1 tablespoon of unsalted butter. This will prevent the casserole from sticking and add a lovely flavor.
-
Add Bread Cubes: Evenly spread the 8 cups of bread cubes into the buttered dish. Use stale or day-old bread for the best texture, allowing it to soak up all that custardy goodness.
-
Whisk Together: In a large bowl, whisk together the 6 large eggs, 1.5 cups of milk, 0.5 cup of heavy cream, both sugars, 1 tablespoon of vanilla extract, cinnamon, nutmeg (if using), and salt. Mix until well combined and slightly frothy.
-
Pour Custard: Gently pour the custard mixture over the bread cubes, ensuring all pieces are soaked. Use your hands to press the bread down slightly; this helps it absorb the liquid.
-
Refrigerate Overnight: Cover the baking dish with plastic wrap or aluminum foil and refrigerate overnight. This step allows the flavors to meld and the bread to soften perfectly.
-
Preheat Oven: The next morning, preheat your oven to 350°F (175°C). Remove the casserole from the fridge while the oven heats up.
-
Dot with Butter: Once the oven is preheated, remove the cover and dot the casserole with the remaining 1 tablespoon of unsalted butter for added richness.
-
Bake Until Golden: Bake in the preheated oven for about 45 minutes or until the casserole is puffed up, golden brown, and a little set on top.
-
Rest, Slice, and Serve: Allow the casserole to rest for about 5-10 minutes before slicing. Serve warm, perhaps with maple syrup or fresh berries on top!
Optional: Add a sprinkle of powdered sugar for an elegant touch before serving.
