INGREDIENTS

- 1/4 teaspoon salt
For the topping:
- 1/2 cup all-purpose flour
- 1/2 cup brown sugar, packed
- 1 teaspoon ground cinnamon

INSTRUCTIONS
Start by preparing your baking dish – a 9×13 inch casserole dish works perfectly. Grease it generously with butter to ensure nothing sticks to the sides.
Spread your bread cubes evenly throughout the dish, making sure they’re packed somewhat tightly but still have room to expand.
In a large bowl, whisk together the eggs, milk, heavy cream, sugars, vanilla, cinnamon, nutmeg, and salt until completely combined.
Take a moment to appreciate the aromatic symphony you’ve created – this is the magic potion that transforms ordinary bread into extraordinary breakfast. Pour this mixture slowly over the bread cubes, making sure to coat each piece.
Use a spatula to gently press down on the bread, helping it absorb the custard. Cover the dish with plastic wrap and refrigerate for at least 4 hours, though overnight is ideal for maximum flavor infusion.
When you’re ready to bake, preheat your oven to 350°F (175°C). While it’s heating, prepare the streusel topping by combining flour, brown sugar, cinnamon, and salt in a medium bowl.
Cut in the cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Stir in nuts if using.
Remove the casserole from the refrigerator, uncover it, and sprinkle the topping evenly over the soaked bread.
Bake in the preheated oven for 45-55 minutes, until the center is set and the top is golden brown and crispy. If the top starts browning too quickly, tent it with aluminum foil.
Allow the casserole to cool for about 10 minutes before serving – this resting period lets the custard set up perfectly. Serve warm with a drizzle of maple syrup, a dusting of powdered sugar, fresh berries, or a dollop of whipped cream – or go wild and add all of the above!

FAQs
1. Can I make this recipe dairy-free?
Absolutely! Substitute the milk and cream with your favorite non-dairy alternatives like almond, oat, or coconut milk.
For the butter in the topping, use a plant-based butter substitute. The texture might be slightly different, but it’ll still be delicious!
2. My bread isn’t stale. What should I do?
Fresh bread works too, but stale bread absorbs the custard better. To quickly “stale” fresh bread, spread the cubes on a baking sheet and bake at 300°F for about 10 minutes, or until they’re dry but not toasted.
3. Can I freeze French Toast Casserole?
Yes! You can freeze it either before or after baking. If freezing before baking, assemble everything except the topping, cover tightly, and freeze for up to 2 months.
Thaw overnight in the refrigerator, add the topping, and bake as directed. If freezing after baking, cool completely, wrap tightly, and freeze for up to 2 months.
Reheat in a 350°F oven until warmed through.
4. How do I know when the casserole is done baking?
The top should be golden brown and crispy, and the center should be set but still slightly jiggly – similar to a bread pudding. If you insert a knife in the center, it should come out clean or with just a few moist crumbs.
5. Can I add fruit to the casserole?
Definitely! Scatter 1-2 cups of fresh or frozen berries, sliced apples, or peaches between the bread cubes before pouring the custard over.
Just note that very juicy fruits might make the casserole slightly more moist.
