This casserole brings the familiar comfort of French toast to the table in a format that is easy to share. Instead of standing over a skillet cooking individual slices, you layer everything in one dish and let the oven do the work.
The contrast of textures makes it especially satisfying. The bread becomes soft and rich from the egg-and-cream custard, while the apples retain enough structure to provide tender fruity bites and the streusel turns crisp on top.
It also fits beautifully into a dinner spread. Serve it as a sweet main dish with crisp bacon, breakfast sausage, or a simple green salad for a relaxed sweet-and-savory meal. If your household prefers a savory baked comfort food on another night, our easy skillet lasagna is another practical one-pan option.
Ingredients You’ll Need
The foundation is one 16-ounce loaf of French bread cut into 1-inch cubes. Day-old bread is ideal because it absorbs the custard while maintaining enough structure to keep the casserole from becoming overly soft.
The custard uses six large eggs, 1 1/2 cups of whole or 2% milk, and one cup of half-and-half. Granulated sugar, vanilla, cinnamon, and salt round out the mixture without overpowering the apples.
- Apples: Choose two medium apples. Granny Smith brings tartness and firmness, while Honeycrisp or Braeburn offers a sweeter flavor with good structure.
- Streusel: Brown sugar, flour, chopped pecans or walnuts, cinnamon, and cold unsalted butter create a crumbly topping with caramel-like flavor.
- Finishing touches: Maple syrup, powdered sugar, or whipped cream can be added just before serving.

How to Make It Step-by-Step
Step 1: Prepare a 9-by-13-inch baking dish by greasing it lightly. Arrange the French bread cubes in an even layer so every section can meet the custard, then scatter the peeled and prepared apples over the bread.
Step 2: Add the eggs, milk, half-and-half, granulated sugar, vanilla, cinnamon, and salt to a large bowl. Whisk until the eggs are fully blended and the mixture looks smooth, with the cinnamon distributed throughout.
Step 3: Pour the custard slowly over the bread and apples, moving around the dish so the liquid is spread evenly. Press down gently with a spatula or the back of a spoon, taking care not to crush the bread cubes.
Step 4: Cover the casserole and refrigerate it for at least 30 minutes. Overnight soaking is recommended when your schedule allows because it gives the custard more time to penetrate the center of the bread.
Step 5: Make the streusel while the casserole chills or just before baking. Stir together the brown sugar, flour, nuts, and cinnamon, then work in the cold butter until the mixture resembles coarse crumbs with a few small buttery pieces remaining.
Step 6: Remove the cover and sprinkle the streusel over the chilled casserole in an even layer. The topping should reach the edges so each serving receives some of the crisp brown-sugar mixture.
Step 7: Bake the casserole uncovered at 350°F (175°C) for 45 to 55 minutes. It is ready when the top is golden and puffed and the center looks set but still tender; if the topping darkens too quickly, cover the dish loosely with foil.
Step 8: Let the baked casserole rest for about 10 minutes before cutting. Serve warm with maple syrup, powdered sugar, or whipped cream, depending on how sweet you want each portion.
Best Apples and Bread for French Toast Casserole
Granny Smith apples are a dependable choice because their tart flavor balances the sweet custard and streusel. They also hold their shape well during the 45-to-55-minute bake, so the finished casserole has recognizable apple pieces instead of an entirely soft filling.
Honeycrisp and Braeburn apples are excellent when you prefer a naturally sweeter result. Golden Delicious apples become softer and milder after baking, which is ideal if you like the fruit to blend gently into the custard.
French bread gives the casserole a pleasantly chewy crumb and crisp edges. If your loaf is fresh, cut it into cubes and dry it in a 300°F oven for about 10 minutes before assembling the dish.
Make-Ahead and Baking Tips
The overnight method is the most convenient approach for entertaining. Assemble the bread, apples, and custard the evening before, cover the dish, and refrigerate it; prepare the streusel separately if you want the topping to remain especially crumbly.
For a shorter schedule, refrigerate the assembled casserole for at least 30 minutes. This is enough time for the bread to absorb some of the liquid, though a longer rest generally produces a more evenly custardy interior.
Watch the casserole near the end of baking rather than relying only on the clock. The center should be set but tender, since overbaking can make the bread dry. If the surface is already deeply golden before the center is ready, loosely tent the dish with foil.
If you slice the apples before assembling, toss them with a small amount of lemon juice to help prevent browning. Do not add enough lemon juice to make the fruit wet, as excess liquid can affect the casserole’s texture.

Serving, Storage, and Reheating
Allowing the casserole to rest for 10 minutes makes it easier to portion and gives the custard time to settle. Spoon or cut generous squares onto plates, then add a thin stream of maple syrup for extra warmth and sweetness.
Powdered sugar gives the top a simple bakery-style finish, while whipped cream makes each serving feel more dessert-like. For a dinner buffet, place the toppings in small bowls so guests can customize their portions.
Store leftovers covered in the refrigerator. Reheat individual servings gently until warm, or warm several portions in a baking dish; avoid prolonged high heat, which can dry the bread and make the streusel less crisp.
Leftover slices can also be served at room temperature for a quick sweet breakfast the next day. If you are planning an apple-themed dessert table, these apple pie egg rolls add a crisp handheld treat alongside the spoonable casserole.
Easy Variations for the Dinner Table
Use pecans for a buttery, rich topping or walnuts for a slightly earthier crunch. Either choice works with the cinnamon and apples, so select the nut your family enjoys most.
You can chop the apples into small pieces for fruit in nearly every bite, or thinly slice them for a more defined apple layer across the top. Keep the total amount to two medium apples so the bread-to-custard balance remains consistent.
For a dessert-forward presentation, add whipped cream and powdered sugar together. For a dinner menu with savory sides, serve the casserole with maple syrup on the side and pair it with salty breakfast meat to balance the sweetness.

Easy Apple French Toast Casserole Recipe
Ingredients
Method
- Grease a 9-by-13-inch baking dish. Spread the cubed French bread evenly in the dish, then scatter the chopped or sliced apples over the top.
- Whisk together the eggs, milk, half-and-half, granulated sugar, vanilla, cinnamon, and salt until smooth. Pour the custard evenly over the bread and apples, pressing the bread down gently so it absorbs the liquid.
- Cover the baking dish and refrigerate for at least 30 minutes or overnight. For the best texture, let the custard soak deeply into the bread before baking.
- Combine the brown sugar, flour, chopped nuts, and cinnamon for the streusel. Cut in the cold butter with your fingers or a pastry cutter until coarse crumbs form.
- Sprinkle the streusel evenly over the chilled casserole. Bake uncovered at 350°F for 45 to 55 minutes, until puffed, golden, and set in the center.
- If the top browns too quickly, cover the dish loosely with foil for the remainder of the baking time. Let the casserole stand for about 10 minutes before serving.
