👩‍🍳 How to Make Apple Cinnamon French Toast Casserole

Step 1: Prepare the Baking Dish

Preheat oven to 350°F (175°C).
Grease a 9×9-inch baking dish.

Step 2: Layer the Bread & Apples

Add half the cubed bread to the dish.
Sprinkle diced apples over the bread.
Add the remaining bread cubes.

Step 3: Make the Custard

In a bowl, whisk together:

Eggs
Milk
Heavy cream
Brown sugar
Vanilla extract
Cinnamon
Nutmeg
Salt

Step 4: Soak the Bread

Pour the custard mixture evenly over the bread.

Let it sit 10–15 minutes so the bread absorbs the liquid.

Step 5: Add Streusel (Optional)

Mix flour, brown sugar, butter, and cinnamon until crumbly.
Sprinkle over the casserole.

Step 6: Bake

Bake for 40–45 minutes until golden brown and set.

Step 7: Serve

Let cool slightly and serve warm with maple syrup or powdered sugar.

🔥 Tips for the Best French Toast Casserole

Use slightly stale bread for better texture.
Cut apples into small cubes so they soften while baking.
Let the bread soak well before baking.
Add extra cinnamon for stronger flavor.

🍏 Best Apples to Use

These apples work best because they hold their shape:

Honeycrisp
Granny Smith
Fuji
Gala

They give the casserole the perfect balance of sweet and tart.
