Pumpkin French Toast Casserole (Cozy Fall Bake)

Let’s Make the Coziest, Most Delicious Fall Breakfast Ever!

Hey there, friend! Is there anything better than a slow, cozy weekend morning in the fall? The crisp air outside, your favorite comfy sweater on, and the unmistakable, heart-warming scent of cinnamon, pumpkin, and toasty bread wafting from your kitchen. That’s the magic I live for, and it’s exactly what this Pumpkin French Toast Casserole is all about. Imagine all the best parts of French toast—the custardy-soft interior, the slightly crisp edges—baked into one glorious, hands-off dish that feeds a crowd (or just your very ambitious breakfast-for-dinner dreams). This isn’t just breakfast; it’s a warm, delicious hug on a plate. It’s the star of the show at holiday brunches, the hero of sleepy Sunday mornings, and the ultimate make-ahead miracle that means you get to be part of the fun, not stuck in the kitchen. So, preheat your oven (and your heart!) and let’s make something incredibly tasty together. Trust me, your fork is ready for this.

The Sunday Morning Symphony

This recipe takes me right back to my grandma’s kitchen. Sunday mornings at her house were a sacred ritual. You’d be woken up not by an alarm clock, but by the sound of her wooden spoon clinking against her big yellow mixing bowl and the heavenly scent of whatever she was whipping up. One particular chilly autumn Sunday, she was making her famous baked French toast, but she had a can of pumpkin purée sitting on the counter from a pie-making session the day before. With a mischievous grin, she looked at me and said, “Let’s experiment, Emmy.” She swirled that gorgeous orange pumpkin and a heavy dose of warm spices right into the custard. What emerged from the oven was nothing short of legendary. It was the first time I truly understood that the best recipes aren’t always planned; sometimes, they’re born from a little bit of curiosity and a whole lot of love. This casserole is my homage to her—and to all the beautiful, delicious kitchen experiments that turn into family traditions.

Gathering Your Autumn Baking Squad

Here’s your shopping list for this cozy masterpiece! Don’t worry, I’ve packed this section with all my favorite chef insights and easy swaps to make this work for you.

• 1 loaf day-old brioche or challah, cubed (about 10 cups): This is the foundation! Stale bread is the secret weapon here—it soaks up the custardy pumpkin mixture without turning to mush. Chef’s Insight: No day-old bread? No problem! Cube fresh bread and toast it on a sheet pan at 300°F for 10-15 minutes to dry it out. Brioche gives a rich, buttery flavor, while challah is wonderfully eggy and soft.
• 6 large eggs: The backbone of our custard, providing structure and richness.
• 1½ cups whole milk & ½ cup heavy cream: This combo creates the most luxurious, creamy base. Substitution Tip: You can use all whole milk, or even half-and-half for the entire liquid amount. For a dairy-free version, unsweetened oat milk or full-fat coconut milk work beautifully!
• 1 cup pumpkin purée: The star of the show! Make sure you’re using 100% pure pumpkin purée, not pumpkin pie filling (which has added sugar and spices).
• ½ cup brown sugar & ¼ cup granulated sugar: Brown sugar brings deep molasses notes that pair perfectly with pumpkin, while granulated sugar adds straightforward sweetness. Chef’s Insight: For a deeper flavor, try using dark brown sugar!
• 2 tsp vanilla extract: The flavor enhancer. It rounds out all the spices and makes everything taste more, well, everything!
• 2 tsp ground cinnamon, ½ tsp ground nutmeg, ¼ tsp ground cloves: The warm, cozy spice brigade. This is the taste of autumn. Substitution Tip: No individual spices? Use 2 ½ – 3 teaspoons of pumpkin pie spice blend instead.
• ¼ tsp salt: Crucial! It balances all the sweetness and makes the flavors pop.

For The Irresistible Crumble Topping:

• ½ cup all-purpose flour: The base of our crunchy streusel.
• ½ cup brown sugar: For sweetness and caramelization.
• 1 tsp cinnamon: Because you can never have too much cinnamon.
• 4 tbsp cold butter, cubed: The key to a perfect crumble is COLD butter. It creates little pockets of steam as it bakes, leading to that irresistible crispy, flaky texture.
• Optional: ½ cup chopped pecans or walnuts: For a delightful crunch and nutty flavor. Absolutely recommend!

Let’s Build This Cozy Masterpiece, Step-by-Step

Don’t let the layers fool you—this is an incredibly simple process. I’m walking you through every step with my favorite kitchen hacks!

1. Prep Your Pan: Grab your trusty 9×13-inch baking dish. Grease it generously with butter or non-stick spray. This is your insurance policy for easy serving later! Now, toss in your cubed bread and spread it into a somewhat even layer. Chef’s Hack: If some pieces are a lot smaller than others, that’s okay! The variety gives you a great mix of super soft and slightly chewy bits.
2. Whisk the Wonder Custard: In a large bowl, crack in your 6 eggs. Give them a preliminary whisk until they’re broken up and smooth. Now, whisk in the whole milk, heavy cream, and pumpkin purée until the mixture is a beautiful, uniform orange. Add both sugars, the vanilla, all the spices, and that very important salt. Whisk, whisk, whisk until everything is completely smooth and combined. Chef’s Tip: If you’re worried about chunks of spice, you can whisk the dry spices into the sugars first to break them up, then add them to the wet ingredients.
3. The Soak: Slowly and evenly, pour your gorgeous pumpkin custard over the bread cubes in the baking dish. Now, here’s a pro move: take your clean hands or a spatula and gently press down on the bread. You’ll hear a satisfying squish as the bread soaks up all that liquid. This ensures every single nook and cranny is saturated for maximum flavor. Chef’s Hack: Toss in any optional nuts at this stage if you want them to get soft and baked into the casserole itself.
4. Patience is a Virtue (Chill Time!): This is the most important step for the perfect texture! Cover the dish tightly with plastic wrap and refrigerate it for at least 4 hours, but ideally overnight. This allows the bread to fully absorb the custard, so you won’t have a pool of liquid at the bottom of your pan. It also means breakfast is DONE when you wake up—just pop it in the oven!
5. Create the Crumble: When you’re ready to bake, preheat your oven to 350°F (175°C). Now, let’s make that topping! In a medium bowl, combine the flour, brown sugar, and cinnamon for the crumble. Add the cold, cubed butter. Using your fingers, a pastry cutter, or even a fork, work the butter into the dry ingredients until the mixture looks like coarse, sandy crumbs with some larger pebbles of butter throughout. Chef’s Hack: If you’re adding nuts for crunch on top, mix them into the crumble now. Sprinkle this heavenly mixture evenly over the entire chilled casserole.
6. Bake to Golden Perfection: Place the uncovered dish in your preheated oven and bake for 45-50 minutes. You’re looking for a golden-brown, crisp topping and a center that is set (it shouldn’t jiggle like liquid when you gently shake the pan). If the top is browning too quickly, you can tent it loosely with foil for the last 10-15 minutes of baking.
7. The Hardest Part: Resting! I know, I know. It smells incredible and you want to dive in. But let it cool on a wire rack for at least 15-20 minutes before slicing. This allows the custard to set fully, making it much easier to serve beautiful squares rather than a delicious but messy scoop.

How to Serve This Autumn Showstopper

This casserole is glorious all on its own, but a few simple toppings can turn it into a true work of art. I love serving it right from the baking dish at the table—it’s so homey and inviting! Slice it into big squares and place them on individual plates. Here’s how I like to gild the lily:

• The Classic: A generous drizzle of pure maple syrup and a dusting of powdered sugar. Simple, elegant, and perfect.
• The Decadent: A dollop of freshly whipped cream or a scoop of vanilla ice cream. Yes, ice cream for breakfast. We’re living life to the fullest over here.
• The Crunchy: An extra sprinkle of those chopped toasted pecans or walnuts for textural contrast.
• The Fruity: A handful of fresh berries (raspberries or strawberries cut through the richness nicely) or even some sautéed apples or pears for a double-down on fall flavors.

Pair it with crispy bacon, savory breakfast sausage, or a simple fruit salad to balance the sweetness. And don’t forget a big pot of hot coffee or a pot of spiced chai tea!

Make It Your Own! Delicious Twists & Swaps

This recipe is like your favorite sweater—incredibly comfortable but easy to accessorize for a different look! Here are some of my favorite ways to mix it up:

1. Apple Pie Twist: Add a layer of flavor! Before adding the bread cubes, scatter 1 ½ cups of finely chopped apples (like Granny Smith or Honeycrisp) over the bottom of the greased pan. Proceed with the recipe as written. The apples bake right into the bottom, creating a spiced apple pie layer.
2. Chocolate Chip Delight: Because pumpkin and chocolate are a match made in heaven. Fold ¾ cup of semi-sweet or dark chocolate chips into the bread cubes before you pour the custard over them. You’ll get melty, gooey pockets of chocolate in every bite.
3. Ginger Snap Crunch: Swap the crumble topping for a crust made from crushed ginger snap cookies! Crush about 15-20 ginger snaps into coarse crumbs and mix with 3 tablespoons of melted butter. Sprinkle over the casserole before baking for a spicy, crunchy top.
4. Gluten-Free & Dairy-Free Friendly: This is an easy one to adapt! Use your favorite gluten-free bread (a sturdy, crusty loaf works best). For the custard, swap the milk and cream for unsweetened almond milk or oat milk, and use a plant-based butter (like Miyoko’s or Earth Balance) in the crumble topping.
5. Extra Protein Boost: Want to make it a more substantial meal? Whisk ½ cup of vanilla or unflavored protein powder into the custard mixture. It incorporates seamlessly and adds a great protein punch.

From My Kitchen to Yours: Chef Emily’s Notes

This recipe has been a labor of love over the years. The first time I tested it for the blog, I was so excited I forgot the sugar in the custard. I served it to my poor, sweet husband who bravely took three bites before gently asking, “Is it… supposed to be savory?” We had a good laugh and doused it in so much syrup it was edible. Lesson learned: always taste your custard! I’ve also learned that the overnight rest is non-negotiable. I’ve tried to rush it for a “quick” version, and while it was still tasty, the texture was nowhere near as perfect. This casserole is a testament to the fact that the best things in life (and in the kitchen) are worth waiting for. It’s my most-requested recipe every Thanksgiving and Christmas morning, and nothing makes me happier than getting texts from you all with pictures of your own beautiful bakes!

Your Questions, Answered!

Q: Can I make this entirely ahead of time and just bake it in the morning?
A: Absolutely! That’s the beauty of it. Assemble the whole casserole (including the crumble topping), cover it tightly, and refrigerate it for up to 24 hours. In the morning, just pop it directly from the fridge into the preheated oven. You might need to add 5-10 minutes to the baking time since it’s starting from cold.

Q: My casserole is still wet in the middle after the baking time. What happened?
A> The most common culprit is not letting it soak long enough. The bread needs those full 4+ hours to drink up the custard. If you’re baking it and find it’s too wet, just cover the top with foil to prevent burning and bake for another 10-15 minutes until set. Also, make sure your oven is at the right temperature—an oven thermometer is a cheap and invaluable tool!

Q: Can I freeze this pumpkin French toast casserole?
A> You can! I recommend freezing it before baking. Assemble the casserole (without the topping), wrap it in a few layers of plastic wrap and foil, and freeze for up to 2 months. Thaw it overnight in the fridge, add the crumble topping, and then bake as directed. You can also freeze baked portions for up to a month. Reheat in the toaster oven or a 350°F oven until warm.

Q: What’s the best way to reheat leftovers?
A> Leftovers?! (Just kidding, I know it happens). The best way to retain the texture is to reheat single servings in the toaster oven or a conventional oven at 350°F for about 10-15 minutes. The microwave will work in a pinch but will make the topping soft.
