Apple cinnamon overnight French toast combines everything you love about classic French toast with the ease of a make-ahead breakfast casserole. Cubes of buttery bread and tender apples soak overnight in a cinnamon-spiced custard, then get topped with a brown sugar streusel before baking. The result is soft and custardy in the center, golden around the edges, and lightly crisp on top.

Because most of the work happens the night before, this recipe is especially helpful when you’re feeding overnight guests or planning a holiday brunch. In the morning, simply add the prepared streusel and place the dish in the oven. By the time the coffee is ready, the kitchen will be filled with the warm scent of baked apples and cinnamon.

Why You’ll Love This Recipe

Traditional French toast is simple enough when you’re cooking for one or two people but preparing individual slices for a larger group can leave you standing at the stove while everyone else eats. Overnight French toast delivers the same familiar flavors in a casserole that can be served all at once.

The overnight rest is about more than convenience. It gives the bread time to absorb the vanilla-scented custard, creating a tender interior without leaving a layer of unabsorbed liquid at the bottom of the dish. Chopped apples add freshness and a hint of tartness, while the buttery cinnamon streusel provides a welcome contrast to the soft bread.

Overnight French toast also works well for occasions that call for something special but not overly elaborate. Serve it for a relaxed fall weekend, Thanksgiving or Christmas morning, a family brunch, or any time you would rather assemble breakfast the night before.

Choosing the Best Bread

The bread is the foundation of this recipe, so choose one that can absorb plenty of custard while still holding its shape. Brioche and challah create a rich, tender casserole with a subtle buttery sweetness. French bread produces a slightly firmer texture, while sourdough adds a pleasant tang that balances the brown sugar and apples.

Day-old bread is ideal because it is dry enough to soak up the egg mixture without immediately falling apart. Cut it into approximately 1-inch cubes so the pieces absorb the custard evenly.

If your bread is fresh, spread the cubes on a rimmed baking sheet and bake them at 300°F for 10 to 15 minutes, stirring once, until they feel dry but have not begun to brown. Allow them to cool before assembling the casserole.

Very soft sandwich bread is less suitable for this recipe. It can break down during the overnight soak and give the finished French toast a dense or soggy texture.

The Best Apples for Overnight French Toast

Firm apples that retain some of their texture when baked are the best choice. Honeycrisp, Pink Lady, Braeburn, Fuji, and Granny Smith apples all work well. Honeycrisp and Pink Lady apples offer a balanced sweet-tart flavor, while Granny Smith apples create a more noticeable tart contrast to the sweet custard and streusel.

Peeling the apples gives the casserole a softer, more uniform texture, but it isn’t essential. If you enjoy the color and slight chew of the peels, you can leave them on. Chop the apples into small, approximately ½-inch pieces so they become tender in the same amount of time it takes the custard to set.

This recipe adds the apples directly to the casserole without precooking them. Keeping the pieces small allows them to soften in the oven while preventing them from releasing too much moisture into the bread.

Recipe: Apple Cinnamon Overnight French Toast 

This make-ahead French toast casserole features tender apples, a warmly spiced custard and a buttery cinnamon streusel. Assemble the casserole and topping the night before, refrigerate them separately, and bring everything together just before baking.

Makes 8 servings

Ingredients

For the French Toast:

• 1 tablespoon unsalted butter, softened, for the baking dish
• 1 large loaf brioche, challah or French bread, preferably day-old, cut into 1-inch cubes (about 10 cups)
• 2 medium firm apples, peeled if desired and cut into ½-inch pieces (about 2 cups)
• 8 large eggs
• 2 cups whole milk
• ½ cup heavy cream or half-and-half
• ⅓ cup packed light brown sugar
• 2 teaspoons vanilla extract
• 2 teaspoons ground cinnamon
• ¼ teaspoon ground nutmeg
• ½ teaspoon kosher salt

For the Cinnamon Streusel:

• ½ cup all-purpose flour
• ½ cup packed light brown sugar
• 1 teaspoon ground cinnamon
• ¼ teaspoon kosher salt
• 6 tablespoons cold unsalted butter, cut into small cubes
• ½ cup chopped pecans or walnuts, optional

For Serving:

• Warm maple syrup
• Confectioners’ sugar, optional
• Whipped cream, optional

Instructions

1. Grease a 9-by-13-inch baking dish with the softened butter.
2. Place half of the bread cubes in the prepared baking dish. Scatter half of the chopped apples over the bread. Add the remaining bread and apples, gently tossing or rearranging them so the fruit is distributed throughout the dish.
3. In a large bowl, whisk the eggs until the yolks and whites are completely blended. Add the milk, heavy cream, brown sugar, vanilla, cinnamon, nutmeg and salt. Whisk until the sugar is mostly dissolved and the mixture is smooth.
4. Slowly pour the custard over the bread and apples, moving around the dish so the liquid is evenly distributed. Gently press the bread into the custard with the back of a spoon or clean hands. Do not compact it tightly; simply make sure the top pieces have been moistened.
5. Cover the baking dish tightly and refrigerate it for at least 6 hours or overnight.
6. To prepare the streusel, combine the flour, brown sugar, cinnamon and salt in a medium bowl. Add the cold butter and use a pastry blender, fork or your fingertips to work it into the dry ingredients until the mixture forms coarse crumbs. Stir in the chopped nuts, if using. Cover and refrigerate the streusel separately overnight.
7. When ready to bake, remove the casserole from the refrigerator and let it stand at room temperature for about 20 minutes. Preheat the oven to 350°F.
8. Uncover the casserole and gently press down any bread cubes that appear dry. Sprinkle the chilled streusel evenly over the top.
9. Bake uncovered for 45 to 55 minutes, until the top is golden brown and the center is set. For a softer, more custardy consistency, bake it closer to 45 minutes. For a firmer casserole with crispier edges, allow it to bake a little longer. If the streusel begins to brown too quickly, loosely cover the dish with aluminum foil for the remainder of the baking time.
10. Let the French toast rest for 10 minutes before serving. Dust it with confectioners’ sugar, if desired, and serve warm with maple syrup or whipped cream.

Tips for the Best Texture

The difference between soft, custardy French toast and a casserole that feels wet or soggy often comes down to the bread. Begin with approximately 10 cups of sturdy, slightly dry bread cubes. If you use less bread—or particularly soft, fresh bread—the casserole may not absorb all the custard.

Take a moment to pour the egg mixture slowly and evenly across the dish. Afterward, gently press the bread down so the exposed cubes are moistened. There is no need to flatten the casserole; you want to keep some of the bread’s natural texture and irregular surface.

The baking time can vary depending on the depth and material of your baking dish, as well as how long the casserole sits at room temperature before going into the oven. It is ready when the top is golden and the center no longer appears liquid when the dish is gently moved. An instant-read thermometer inserted into the center should register 160°F.

Finally, allow the casserole to rest for about 10 minutes after baking. This short pause lets the custard settle, making the French toast easier to portion without losing its soft interior.

Do You Have to Refrigerate It Overnight?

An overnight soak gives the bread plenty of time to absorb the custard, but you don’t have to wait until the following morning to bake the casserole. If you’re making it on the same day, refrigerate it for at least two hours before baking. The texture may be slightly less uniform, but the bread will still have time to take in much of the liquid.

Whether the casserole rests for two hours or overnight, keep it refrigerated until shortly before baking. Because the custard contains raw eggs and dairy, the assembled dish should not be left at room temperature for an extended period.

For the best balance of convenience and texture, assemble the casserole after dinner and refrigerate it for 8 to 12 hours. It will be ready to top and bake first thing in the morning.

Recipe Variations

Once you have made overnight French toast, it’s easy to adapt the casserole to suit the occasion. For caramel apple French toast, drizzle warm caramel sauce over each serving rather than adding it before baking. This allows everyone to control the sweetness and keeps the caramel from disappearing into the custard.

For additional crunch, stir toasted pecans or walnuts into the streusel. Dried cranberries can be scattered among the apples for a tart, chewy accent, while golden raisins add a softer, sweeter flavor.

You can also replace the brown sugar in the custard with ¼ cup of pure maple syrup. The finished casserole will have a gentle maple flavor and taste especially good with toasted pecans. For a more complex spice blend, add a pinch of ground ginger, cardamom or allspice along with the cinnamon and nutmeg.

What to Serve with Apple Cinnamon Overnight French Toast

Because this French toast is rich and lightly sweet, it pairs particularly well with something savory. Crisp bacon, breakfast sausage or a simple vegetable frittata can turn it into a complete brunch. A platter of softly scrambled eggs is another easy option when serving a larger group.

For a lighter contrast, offer plain Greek yogurt and fresh fruit. A citrus salad made with oranges and grapefruit provides bright acidity that cuts through the creamy custard and buttery streusel.

Hot coffee and tea are natural companions, while warm apple cider reinforces the cozy fall flavors. For a celebratory brunch, serve it alongside mimosas or a simple sparkling apple cider.

Make-Ahead, Storage and Reheating

The unbaked casserole can be assembled up to 24 hours in advance. Keep it tightly covered in the refrigerator and store the streusel in a separate covered container. Waiting to add the topping preserves its crumbly texture and prevents the flour and sugar mixture from absorbing moisture from the custard.

Refrigerate leftover baked French toast in an airtight container, or cover the baking dish tightly, for up to three days. Individual portions can be warmed in the microwave, although the topping will become softer. To restore some of the crispness, reheat the casserole in a covered 325°F oven until warmed through, then uncover it for the final few minutes.

The baked casserole can also be frozen for up to two months. Allow it to cool completely, divide it into portions and wrap each portion well before placing it in a freezer-safe container. Thaw the French toast overnight in the refrigerator and reheat it in the oven or microwave. Freezing the casserole in individual servings makes it easy to enjoy a warm breakfast without reheating the entire dish.

Frequently Asked Questions

Can I assemble the casserole the same morning?

Yes. Let the assembled casserole soak in the refrigerator for at least two hours before baking. An overnight rest produces the most evenly custardy texture, but a shorter soak will still work when you haven’t planned the breakfast a day in advance.

Does the bread have to be stale?

The bread doesn’t need to be noticeably hard, but it should be somewhat dry. Dry bread absorbs the custard more readily while maintaining its structure. Fresh bread can be dried in a 300°F oven for 10 to 15 minutes and cooled before use.

Do I need to peel the apples?

No. Peeling is a matter of personal preference. Peeled apples blend more seamlessly into the soft casserole, while unpeeled apples provide a little extra color and texture. Either way, cut them into small pieces so they become tender during baking.

Why is my overnight French toast soggy?

Sogginess can be caused by using too little bread, choosing bread that is too soft or underbaking the casserole. Make sure you have about 10 cups of sturdy bread cubes and bake until the middle is set rather than visibly wet. The casserole will remain soft and custardy, but it should hold its shape when served.

How can I tell when the center is fully baked?

The center should look set and should not release liquid when gently pressed. A knife inserted near the middle should come out moist but without uncooked custard clinging to it. For the most reliable check, the center should reach 160°F on an instant-read thermometer.

Can I make it without the streusel?

Absolutely. The casserole will still have plenty of apple-cinnamon flavor without the topping. Before baking, sprinkle the surface lightly with cinnamon sugar or add a handful of chopped nuts for a simpler finish.

A Cozy Breakfast Without the Morning Rush

Apple cinnamon overnight French toast has all the warm, comforting qualities of a special brunch without requiring a busy morning in the kitchen. The apples become tender, the bread turns soft and custardy, and the buttery streusel bakes into a crisp golden topping.

Prepare it before bed, then bake it while everyone settles in with coffee the next morning. Served with warm maple syrup and a few simple sides, it’s an easy breakfast that feels generous, seasonal and worthy of sharing.
