APPLES: heat a medium skillet over medium-high heat. Add 2 tablespoons of butter to the skillet and allow it to melt. When melted, add 2 tablespoons of granulated sugar and 1/2 teaspoon of cinnamon to the skillet. Stir to combine. Toss the apples in the butter mixture. Stir as needed and let the apples cook for 5 minutes or until softened. Remove; let cool.
CASSEROLE: Spray a 9x13 baking dish with non-stick spray. Place the diced bread in the pan and layer on the cooked apples; set aside. In a medium bowl, combine the sugar (1/2 cup if serving with maple syrup or 1 cup if serving on it's own with sour cream icing) milk, cream, eggs, vanilla, nutmeg, and 1 teaspoon cinnamon. Pour the prepared custard over the bread and apples.
STREUSEL: combine the light brown sugar, remaining 4 tablespoons of butter (diced), all-purpose flour, and remaining 1 teaspoon of ground cinnamon in a small bowl. Using your fingertips, mix together until the butter breaks down into smaller pieces. Sprinkle over prepared casserole. Cover and refrigerate for at least 3-4 hours and preferably overnight.
BAKE: Position a rack in the center of the oven and preheat oven to 350ºF. Bake the casserole for 45-55 minutes or until the casserole is no longer jiggly. You may need to tent the casserole with a piece of foil if it starts browning too quickly.
Notes
butter: just use a pinch of salt wherever the butter is called for if you've got unsalted
sugar: If you're serving this casserole with my sour cream icing, use 1 cup of sugar for the casserole portion. If you're serving this with maple syrup, use 1/2 cup granulated sugar. You'll also need 2 tablespoons of sugar for the apples.
french bread: you can also use brioche or challah bread
milk + heavy cream substitutes: for a dairy-free option, replace the milk with almond, soy, coconut or cashew milk. Substitute coconut cream for the heavy cream
sour cream icing: whisk together 1 tablespoon of sour cream, 1/3 cup of powdered sugar, and 1-2 tablespoons of milk. Drizzle on the casserole and enjoy!
