Cozy Apple Cinnamon Sourdough French Toast Casserole Recipe with Bourbon Maple Syrup

I did not trust sourdough bread in a French toast casserole. Honestly, it sounded like a mistake until a chilly Sunday morning forced me to rethink what cozy breakfast really meant. There I was, staring at a hefty loaf of tangy sourdough that felt way too rustic for the sweet, soft, custard-soaked dream I had in my head. My gut said, “Stick with classic white bread or brioche for that melt-in-your-mouth vibe.” But stubborn as I am, I decided to give that sourdough a shot—paired with crisp apples and a hint of cinnamon, no less.

The kitchen filled with the smell of warm spices and caramelizing apples, and slowly, the crisp edges of the sourdough softened into something unexpectedly tender without losing its character. The bourbon maple syrup drizzled on top wasn’t just a syrup—it was a warm hug in liquid form, adding a subtle smoky sweetness that cut through the richness perfectly. It was clear that this was no ordinary French toast casserole.

I kept thinking about how this recipe had snuck up on me, turning my skepticism into a quiet, satisfied trust. It’s the kind of breakfast that sits with you, not just filling your stomach but quietly nudging you to slow down and savor the moment—something I didn’t expect from a dish with a name that long.

That’s why this cozy apple cinnamon sourdough French toast casserole with bourbon maple syrup stuck with me. It’s honest, comforting, and just a little bit unexpected—much like the mornings I want to remember.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, with the exception of a few fresh items like apples and sourdough bread, which you can easily adjust depending on what you have on hand.

• Sourdough Bread: About 1 pound (450g), preferably a day or two old for better soaking.
• Apples: 2 medium-sized, peeled and thinly sliced (I like Granny Smith for its tartness, but Honeycrisp works well too).
• Eggs: 6 large, room temperature (use organic or free-range if possible).
• Whole Milk: 2 cups (480ml) – you can swap with almond or oat milk for a dairy-free twist.
• Heavy Cream: 1/2 cup (120ml) – adds richness but can be replaced with more milk.
• Brown Sugar: 1/4 cup (50g) – for subtle caramel notes.
• Cinnamon: 2 teaspoons ground cinnamon, the heart of the spice blend here.
• Vanilla Extract: 1 tablespoon – pure vanilla adds warmth and depth.
• Salt: A pinch – balances the sweetness.
• Unsalted Butter: 2 tablespoons, melted and cooled (adds a lovely richness).
• Bourbon: 2 tablespoons – optional but highly recommended for that smoky maple syrup kick.
• Maple Syrup: 1/2 cup (120ml) pure maple syrup for the syrup base.
• Powdered Sugar: For dusting (optional, but pretty).

For best results, I pick sourdough from a trusted local bakery or make my own. If you want to swap out the apples, pears or firm stone fruits can be a nice seasonal alternative. Substitutions like using coconut milk instead of dairy milk or skipping the bourbon for a kid-friendly version work well too.

Equipment Needed

• 9×13-inch Baking Dish: A standard glass or ceramic casserole dish works well to hold everything evenly.
• Mixing Bowls: One large bowl for the custard and another for tossing apples.
• Whisk: For blending eggs and milk thoroughly.
• Sharp Knife and Cutting Board: To slice apples and bread.
• Measuring Cups and Spoons: To get ingredient amounts just right.
• Small Saucepan: To make the bourbon maple syrup.
• Spatula: Helpful for gently mixing and transferring ingredients.

If you want to get fancy, a handheld milk frother can help mix the custard smoothly (I admit I sometimes skip this step without issue). No need for pricey gadgets—standard kitchen tools will do just fine. I find a ceramic baking dish heats evenly and gives the crust a nice golden color, but a metal pan works well too.

Preparation Method

1. Prepare the Bread and Apples (10 minutes): Cut your sourdough loaf into roughly 1-inch (2.5 cm) cubes. Peel, core, and thinly slice the apples. Toss the apples with a teaspoon of cinnamon and a tablespoon of brown sugar to bring out their natural sweetness. Set both aside.
2. Make the Custard (5 minutes): In a large mixing bowl, whisk together the eggs, whole milk, heavy cream, brown sugar, remaining cinnamon, vanilla extract, and a pinch of salt until fully combined. This custard should be smooth with no egg streaks. A well-mixed custard is key to avoiding clumps and ensuring every bite is custardy.
3. Assemble the Casserole (5 minutes): Grease your 9×13-inch baking dish with butter. Spread half the bread cubes evenly in the dish, then layer half the apple mixture on top. Repeat with the remaining bread and apples. Pour the custard evenly over the entire casserole, pressing down gently to submerge the bread. This helps the sourdough soak up the custard without drying out.
4. Soak (Optional, but Recommended): Cover the dish with plastic wrap and refrigerate for at least 1 hour, or overnight if you want to prep ahead. This step lets the bread soak up the custard fully, yielding a custardy, tender center that’s worth the wait.
5. Bake the Casserole (50-60 minutes): Preheat your oven to 350°F (175°C). Remove the plastic wrap and bake uncovered until the top is golden brown and the custard is set but still slightly jiggly in the center. A toothpick inserted in the middle should come out mostly clean. If the top browns too quickly, loosely tent with foil.
6. Prepare the Bourbon Maple Syrup (10 minutes): While the casserole bakes, combine maple syrup and bourbon in a small saucepan over low heat. Warm gently, stirring occasionally until just heated through. Avoid boiling to keep the syrup smooth and aromatic. This syrup is a game-changer with its smoky sweetness.
7. Serve: Once baked, let the casserole rest for 5-10 minutes. Dust with powdered sugar if desired, then drizzle generously with the warm bourbon maple syrup. The contrast of warm syrup and tender casserole is pure comfort.

Tip: If you forget to soak overnight, no worries—bake immediately but expect a slightly firmer texture. For a more evenly browned top, I sometimes broil for the last 2 minutes but watch it closely to avoid burning.

Cooking Tips & Techniques

Cooking this cozy apple cinnamon sourdough French toast casserole is straightforward, but a few tricks can really improve your results.

• Use Day-Old or Stale Sourdough: Fresher bread can turn soggy and mushy. Slightly stale bread soaks up the custard better, holding texture after baking.
• Don’t Skip the Soak: Overnight soaking lets flavors meld and ensures every bite is custardy. If you’re in a rush, soak for at least 30 minutes.
• Watch Your Oven Temperature: Too hot, and the casserole browns too fast on top but stays undercooked inside. I use an oven thermometer to keep it steady at 350°F (175°C).
• Layer Apples Evenly: This prevents apple-heavy or bread-heavy bites and balances tartness with sweetness.
• Make the Bourbon Maple Syrup Last Minute: Heat gently to keep that bourbon aroma fresh and avoid burning off the alcohol completely.
• Don’t Overmix the Custard: Whisk just until combined to avoid tough eggs in the bake.

Honestly, the first few times I tried this recipe, I rushed through the soaking and ended up with a dense casserole. Now, I never skip the chill time and it makes all the difference. Also, if you’re a fan of crisp edges, buttering the baking dish generously helps create that golden, crunchy crust.

Variations & Adaptations

This recipe is flexible enough for you to make it your own. Here are some variations I’ve enjoyed or recommend:

• Gluten-Free Version: Substitute gluten-free sourdough or a sturdy gluten-free bread. Adjust soak time slightly as gluten-free breads absorb liquid differently.
• Fruit Swaps: Swap apples for pears, peaches, or a mix of berries in summer. Just reduce sugar slightly for naturally sweeter fruit.
• Spice It Up: Add a pinch of nutmeg, cardamom, or even ground ginger to the custard for a warm, spicy twist.
• Bourbon-Free Syrup: Skip the bourbon and add a splash of vanilla or almond extract to the maple syrup for a kid-friendly version.
• Nutty Crunch: Top with chopped pecans or walnuts before baking for texture contrast.

One of my favorite takes was swapping apples for ripe peaches in late summer, paired with a drizzle of honey instead of maple syrup—totally different vibe, equally cozy. For an easy fall baking feel, I sometimes sprinkle pumpkin pie spice on top before baking.

Serving & Storage Suggestions

This French toast casserole is best served warm, fresh out of the oven, with a generous drizzle of the bourbon maple syrup. A dusting of powdered sugar adds a pretty finishing touch and a little extra sweetness.

Pair it with crisp bacon or sausage for a savory balance, or a simple side of fresh fruit for brightness. If you want something lighter, a cup of black coffee or chai tea complements the warm spices beautifully.

To store, cover leftovers tightly and refrigerate for up to 3 days. Reheat gently in the oven at 300°F (150°C) for 10-15 minutes or until warmed through to avoid sogginess. The flavors actually deepen overnight, making it a perfect make-ahead dish for busy mornings.

Freezing is an option too—wrap portions individually in plastic wrap and foil, freeze up to a month. Thaw in the fridge overnight before reheating.

Nutritional Information & Benefits

Each serving of this cozy apple cinnamon sourdough French toast casserole offers a balanced mix of protein from eggs, fiber and vitamins from apples, and moderate carbs for sustained energy. The cinnamon adds antioxidant benefits and may help with blood sugar regulation, while the bourbon maple syrup, used sparingly, enhances flavor without overwhelming sweetness.

For those mindful of dairy, substituting plant-based milk keeps it vegan-friendly (skip eggs or use a vegan egg replacer). Although this recipe contains gluten in sourdough, swapping for gluten-free bread makes it suitable for gluten intolerances.

I find this dish hits that sweet spot of indulgence and nourishment—comfort food that doesn’t leave you feeling weighed down.
