A white baking dish holds a multi-layered baked dessert with three visible layers. The bottom layer is made of soft cooked apple slices, pale yellow in color, resting on a thin, golden crust. Above this, there is a thick, light brown crumbly streusel layer that looks crunchy and uneven, covering the apples. A thin, slightly shiny drizzle of white icing runs lightly across the top streusel layer in wavy lines. The edges of the dish show some baked-on residue, adding a homemade feel. The white marbled surface beneath the dish adds a clean, bright background. photo taken with an iphone --ar 2:3 --v 7 - Apple French Toast Casserole, cinnamon apple breakfast bake, make-ahead apple casserole, cozy breakfast recipes, easy apple brunch idea

Ingredients You’ll Need

Every ingredient in this Apple French Toast Casserole Recipe plays a vital role. The day-old French bread soaks up that rich custard beautifully, while the apples bring a fresh, fruity sweetness with a perfect hint of cinnamon. I always recommend picking crisp apples and fresh dairy for the best results.

Apples: I prefer tart but not too sour varieties like Granny Smith or Fuji — they hold their shape nicely after cooking.
Salted Butter: Adds richness and helps caramelize the apples; salted works best for seasoning control.
Granulated Sugar: Balances the tartness of the apples and adds sweetness.
Ground Cinnamon: I love sprinkling it in two places to maximize that warm, comforting flavor.
French Bread: Day-old is perfect because it’s slightly stale, so it absorbs the custard without becoming mushy.
Milk: Whole milk gives the custard a creamy texture, but you can use 2% if that’s what you have.
Heavy Cream: This elevates the custard’s richness—don’t skip it!
Large Eggs: Act as the binder for the custard, giving the casserole its structure.
Vanilla Extract: I always use pure vanilla for that nuanced depth of flavor.
Nutmeg: Just a pinch adds a perfect hint of warmth without overpowering the cinnamon.
Light Brown Sugar: Creates the sweet, caramelized topping in the streusel.
All-Purpose Flour: Helps bind the streusel topping while keeping it tender and crumbly.

Variations

I love making this Apple French Toast Casserole Recipe my own, depending on the season or what I have on hand. Feel free to switch things up—this dish is forgiving and fun to experiment with.

Use Different Fruits: I’ve tried pears or berries instead of apples, and they both bring a lovely twist—just adjust cooking time based on fruit softness.
Dairy-Free Version: Swap out milk and cream for almond or oat milk, and use vegan butter to keep it dairy-free, though the texture will be slightly lighter.
Crunchy Nut Topping: Add chopped pecans or walnuts to the streusel for a bit of extra crunch, which my family absolutely adores.
Savory Twist: I once made this with a sprinkle of sharp cheddar and thin apple slices for brunch—it was a surprising hit!

How to Make Apple French Toast Casserole Recipe

Step 1: Sauté the Apples to Perfection

Start by heating a skillet over medium-high heat and melting 2 tablespoons of butter. Once melted, stir in 2 tablespoons granulated sugar and 1/2 teaspoon cinnamon—this little sugar-cinnamon combo caramelizes beautifully with the apples. Toss sliced apples into the skillet and cook for about 5 minutes, stirring occasionally until they soften just right. Don’t overcook them; you want tender but still slightly firm apples that hold their shape in the casserole. Once done, remove from heat and let them cool. This caramelizing step is what really makes this Apple French Toast Casserole Recipe stand out!

Step 2: Assemble the Bread and Apples

Spray a 9×13-inch baking dish with non-stick spray—it helps with cleanup and prevents sticking. Place your diced day-old French bread evenly in the dish, then evenly layer those beautiful sautéed apples over the bread. This layering ensures every bite gets some apple goodness.

Step 3: Prepare and Pour the Custard

In a medium bowl, whisk together sugar (adjust based on whether you’ll serve with syrup or sour cream icing), milk, heavy cream, eggs, vanilla, nutmeg, and a teaspoon of cinnamon. This custard base is luscious and fragrant, and once poured over the bread and apples, it’ll soak everything up so wonderfully. Pour it evenly over your assembled casserole, pressing lightly so the bread absorbs the custard.

Step 4: Mix and Sprinkle the Streusel Topping

Mix light brown sugar, the remaining diced butter, flour, and 1 teaspoon cinnamon until crumbly using your fingertips. This streusel topping is the secret weapon in my Apple French Toast Casserole Recipe—it adds that sweet, buttery crunch on top that everyone complains about when it’s missing. Sprinkle it evenly over the custard-soaked bread and apples.

Step 5: Refrigerate and Bake

Cover the dish and refrigerate for at least 3-4 hours, preferably overnight—this step allows the custard to fully soak into the bread, making every bite tender and rich. When you’re ready to bake, preheat your oven to 350°F with the rack in the center. Bake for 45-55 minutes until the casserole is set and no longer jiggly. If the top browns too fast, tent it loosely with foil. Trust me, this overnight soak is what turns this Apple French Toast Casserole Recipe from good to unforgettable!

Pro Tips for Making Apple French Toast Casserole Recipe

Use Day-Old Bread: Fresh bread can get too soggy; day-old or slightly stale bread soaks the custard evenly without falling apart.
Don’t Skip the Sautéed Apples: Cooking the apples beforehand releases their natural sweetness and prevents watery casserole.
Cover While Refrigerating: Keeping the casserole covered overnight helps flavors meld and prevents it from drying out.
Watch for Browning: Tent with foil if the topping browns too quickly to avoid burnt streusel.

How to Serve Apple French Toast Casserole Recipe

The dish shows a white baking dish filled with a layered dessert that has a golden brown crumb topping with a rough, crumbly texture. A woman's hand is holding a spoon above the dish, slowly pouring a smooth, creamy white sauce over the crumbly top layer, creating small pools of sauce on the uneven surface. The dessert appears dense and thick with visible pieces of baked dough beneath the crumbly layer. The background and surface are white with a marbled texture. photo taken with an iphone --ar 2:3 --v 7 - Apple French Toast Casserole, cinnamon apple breakfast bake, make-ahead apple casserole, cozy breakfast recipes, easy apple brunch idea

Garnishes

I usually top my Apple French Toast Casserole with a simple dusting of powdered sugar and a drizzle of sour cream icing because it adds just the right tangy creaminess that balances the sweet cinnamon and apples. Sometimes, if I’m feeling indulgent, I throw on some chopped toasted pecans for extra texture and nutty flavor. A drizzle of warm maple syrup doesn’t hurt either if you like it sweeter.

Side Dishes

Since the casserole is rich and filling, I like to keep sides light and fresh. A simple green salad with a citrus vinaigrette or some fresh berries on the side pairs perfectly. For a cozy brunch, crispy bacon or sausage links add a savory counterpoint that my family always asks for.

Creative Ways to Present

For holiday mornings or special occasions, I’ve served this Apple French Toast Casserole Recipe in individual ramekins instead of one big dish—it makes plating elegant and mess-free. Another favorite is adding a dollop of whipped cream and sprinkling a little extra cinnamon right before serving, which turns an everyday breakfast into a fancy brunch treat.

Make Ahead and Storage

Storing Leftovers

Leftovers? No problem. After cooling completely, I cover the casserole tightly with plastic wrap or foil and store it in the fridge. It keeps well for up to 3 days and still tastes great when reheated gently.

Freezing

I’ve also frozen portions wrapped tightly in foil and stored in freezer bags. When you’re ready to enjoy, just thaw overnight in the fridge and reheat. Freezing doesn’t affect the texture much, so it’s perfect for saving time on busy mornings.

Reheating

To reheat, I find warming single portions in the microwave works fine, but for best texture, I pop leftovers in a 350°F oven for 10-15 minutes until warmed through. This helps keep the deliciously crisp topping refreshed without drying out the custard inside.

FAQs

Can I use a different type of bread for this Apple French Toast Casserole Recipe?

Absolutely! While day-old French bread is ideal because of its firmness and absorbency, you can also use challah, brioche, or even sturdy sandwich bread. Just be mindful that sweeter or softer breads may affect texture and sweetness.
How far ahead can I assemble the casserole before baking?

You can assemble and refrigerate your Apple French Toast Casserole Recipe for up to 24 hours ahead of time. This gives the custard time to soak perfectly into the bread and meld flavors.
Do I have to cook the apples before adding them?

Cooking the apples before adding them is highly recommended. It softens them slightly and lets the natural sugars caramelize, giving a deeper flavor and preventing excess moisture from making the casserole soggy.
Can I make this gluten-free?

You can try substituting gluten-free bread and gluten-free flour in the streusel topping. The texture will be a bit different, but the casserole will still be delicious.

Final Thoughts

When I first made this Apple French Toast Casserole Recipe, I was surprised by how something so simple could warm up my entire morning.

So grab those apples and French bread, and let’s make some memories (and incredible breakfasts) together!
