Pumpkin French Toast Casserole with Pecan Streusel

This Pumpkin French Toast Casserole is everything I love about fall breakfast in one delicious baking dish! Soft, buttery brioche bread is soaked in a rich pumpkin spice custard, then topped with a sweet, crunchy brown sugar pecan streusel and baked until golden brown.

And let me tell you, that streusel topping is something special.

You get soft, custardy pumpkin French toast underneath and buttery, cinnamon-spiced crumbs with crunchy pecans on top. Add a drizzle of warm maple syrup, and you’ve got the kind of breakfast that makes everyone want to come back for seconds.

The best part? You can prepare this overnight pumpkin French toast casserole the evening before and bake it fresh the next morning.

That means no standing over the stove making individual slices of French toast while everyone else is enjoying breakfast.

Whether you’re planning a cozy fall weekend, hosting a holiday brunch, or looking for something special to serve on Thanksgiving morning, this easy pumpkin French toast bake is a wonderful way to start the day.

Why You’ll Love This Pumpkin French Toast Casserole

There are plenty of pumpkin breakfast recipes out there, but this one is especially good when you want something comforting that doesn’t require a lot of morning prep work.

Here’s why I love it:

• Perfect for fall: Real pumpkin puree, pumpkin pie spice, and brown sugar bring all those cozy fall flavors together.
• Make-ahead friendly: Assemble the casserole the night before and refrigerate until you’re ready to bake.
• Buttery brioche bread: The rich, soft bread absorbs the pumpkin custard beautifully.
• Crunchy pecan streusel: A sweet, buttery crumb topping adds the perfect contrast to the soft French toast.
• Easy to feed a crowd: Everything bakes together in one 9×13-inch casserole dish.
• Simple ingredients: You only need everyday baking staples and a can of pure pumpkin.
• Perfect for holidays: This is a great breakfast for Thanksgiving morning, Christmas brunch, or a cozy fall gathering.

And because everything bakes together, you’re not spending your morning flipping French toast one slice at a time.

What Is Pumpkin French Toast Casserole?

Pumpkin French toast casserole is essentially baked French toast made with a pumpkin-spiced egg custard.

Instead of dipping individual slices of bread into an egg mixture, you cut the bread into chunks, place them in a baking dish, and pour the custard over everything.

As the casserole bakes, the bread absorbs the pumpkin mixture and becomes soft and custardy in the center.

For this version, we’re taking things one step further with a homemade brown sugar pecan streusel.

The topping bakes into a sweet, slightly crisp layer that makes the entire casserole taste a little like pumpkin coffee cake and French toast combined.

It’s the perfect combination of textures.

Ingredients You’ll Need

This pumpkin French toast casserole recipe has two components: the pumpkin French toast base and the buttery pecan streusel topping.

For the Pumpkin French Toast Casserole

Brioche bread — 1 loaf

Brioche is my favorite kind of bread for this recipe because it’s naturally rich, buttery, and slightly sweet. It absorbs the pumpkin custard while maintaining enough structure to give the casserole a wonderful texture.

Milk — 1½ cups

Milk combines with the eggs and pumpkin puree to create the custard. Whole milk is a great choice because it adds richness without making the casserole overly heavy.

Pure pumpkin puree — 1 cup

Make sure you’re using 100% pure pumpkin puree, not pumpkin pie filling or pumpkin pie mix. Pure pumpkin provides real pumpkin flavor without additional sugar or spices.

Large eggs — 5

The eggs help the custard set during baking and give the French toast its soft, rich texture.

Vanilla extract — 2 teaspoons

Vanilla brings warmth and sweetness to the pumpkin mixture and complements the pumpkin pie spice.

White sugar — ¼ cup

A little granulated sugar sweetens the custard without making the casserole overly sweet, especially since we’re adding a brown sugar streusel topping.

Pumpkin pie spice — 1 tablespoon

Pumpkin pie spice gives this breakfast its signature fall flavor. It’s typically a combination of cinnamon, ginger, nutmeg, and other warm spices.

For the Brown Sugar Pecan Streusel

Butter — ⅓ cup, melted

Melted butter brings the topping together and helps create those delicious buttery crumbs.

Chopped pecans — ⅓ cup

Pecans add a wonderful nutty flavor and a little crunch. They pair beautifully with pumpkin and brown sugar.

Brown sugar — ½ cup

Brown sugar adds a deeper, caramel-like sweetness to the streusel.

All-purpose flour — ½ cup

Flour helps create the crumbly texture that makes streusel so good.

White sugar — 2 tablespoons

Granulated sugar adds sweetness and contributes to the lightly crisp topping.

Pumpkin pie spice — 1 teaspoon

A little extra pumpkin pie spice gives the topping the same cozy flavor as the casserole underneath.

How to Make Pumpkin French Toast Casserole

This is one of those recipes that looks impressive but comes together with surprisingly little effort.

Step 1: Prepare the Baking Dish

Lightly grease a 9×13-inch baking dish with nonstick cooking spray or butter.

Make sure to coat the bottom and sides so the casserole releases easily after baking.

Step 2: Cut the Brioche Bread

Cut or tear your loaf of brioche into bite-sized bread chunks.

Place the bread cubes into the prepared baking dish, spreading them out evenly.

You don’t need to arrange them perfectly. Just make sure the bread is distributed throughout the pan.

Step 3: Make the Pumpkin Custard

In a large mixing bowl, whisk together:

• 1½ cups milk
• 1 cup pure pumpkin puree
• 5 large eggs
• ¼ cup white sugar
• 1 tablespoon pumpkin pie spice
• 2 teaspoons vanilla extract

Whisk until everything is smooth and evenly combined.

You want the pumpkin completely incorporated into the egg mixture so every bite of French toast gets that delicious pumpkin spice flavor.

Step 4: Pour the Custard Over the Bread

Slowly pour the pumpkin mixture over the bread cubes.

Gently stir or press the bread down to help each piece absorb some of the custard.

Try to make sure all the bread gets coated rather than leaving dry pieces sitting on top.

Step 5: Prepare the Pecan Streusel

In a medium bowl, combine:

• ½ cup all-purpose flour
• ½ cup brown sugar
• 2 tablespoons white sugar
• 1 teaspoon pumpkin pie spice
• ⅓ cup chopped pecans

Stir everything together.

Pour in ⅓ cup melted butter and mix until the topping becomes crumbly.

You should have a mixture of small and larger buttery crumbs.

There’s no need to use a pastry cutter because we’re working with melted butter rather than cold butter.

Step 6: Add the Streusel Topping

Sprinkle the brown sugar pecan streusel evenly over the top of the casserole.

Try to distribute it throughout the dish so every serving gets some of that delicious topping.

Step 7: Bake Covered

Preheat your oven to 350°F.

Cover the baking dish with aluminum foil.

Bake for 40 minutes.

Keeping the casserole covered during the first part of baking helps the custard cook through without allowing the topping to brown too quickly.

Step 8: Bake Uncovered

Carefully remove the aluminum foil.

Continue baking for another 15–20 minutes, or until the top is golden brown and the center is set.

The total baking time will be approximately 55–60 minutes.

To check doneness, insert a toothpick into the center. It shouldn’t come out coated in wet, uncooked custard. For a more reliable check, use an instant-read thermometer and look for at least 160°F in the center of the egg-based casserole.

Step 9: Serve Warm

Allow the casserole to rest for approximately 10 minutes before serving.

Then slice into generous portions and serve warm.

I love adding a drizzle of maple syrup, although the brown sugar pecan streusel already gives this casserole plenty of sweetness.

How to Make Overnight Pumpkin French Toast Casserole

One of my favorite things about this recipe is that you can do almost all the prep work the night before.

This makes it especially convenient for holidays when you want a homemade breakfast without spending the entire morning in the kitchen.

Here’s how to prepare it ahead of time.

The night before:

1. Grease your 9×13-inch baking dish and add the brioche bread cubes.
2. Whisk together the pumpkin custard and pour it over the bread.
3. Gently press the bread into the mixture.
4. Cover the casserole tightly with aluminum foil and refrigerate overnight.
5. Prepare the pecan streusel in a separate bowl, cover it, and refrigerate.

The next morning:

1. Preheat your oven to 350°F.
2. Remove the casserole from the refrigerator.
3. Sprinkle the prepared streusel evenly over the top.
4. Cover with aluminum foil and bake for 40 minutes.
5. Remove the foil and continue baking for another 15–20 minutes, or until the center is set and the topping is golden brown.

A cold casserole may need a little additional baking time. If you’re using a glass baking dish, follow the manufacturer’s guidance about temperature changes to avoid thermal shock.

That’s it!

All the prep work is already done, and you get to enjoy freshly baked pumpkin French toast casserole without the morning rush.

What Is the Best Bread for French Toast Casserole?

The bread you choose makes a big difference in the finished texture.

For this recipe, I recommend brioche, but there are several options.

Brioche Bread

Brioche is my first choice.

It’s rich, buttery, and slightly sweet, making it perfect for a pumpkin-spiced custard.

Challah Bread

Challah is another excellent option.

It’s soft and egg-rich, with enough structure to absorb the custard without immediately falling apart.

French Bread

French bread creates a slightly firmer, chewier French toast casserole.

It’s a good option if you prefer a more substantial texture.

Regular White Bread

You can use thick slices of white bread, but I recommend choosing a sturdy loaf rather than very thin sandwich bread.

Delicate bread can become overly soft after soaking in the custard.

Should You Use Fresh or Stale Bread?

Slightly stale bread is actually wonderful for French toast casserole.

Bread that’s had a little time to dry out can absorb the custard without becoming overly mushy.

If you’re using very fresh brioche, you can cut it into cubes and let it sit out for a little while before assembling the casserole.

You can also spread the bread cubes on a baking sheet and briefly dry them in a low oven.

You don’t want to toast them until they’re hard and crunchy. You’re simply removing a little moisture.

That helps the bread absorb the pumpkin mixture more evenly.

Pumpkin Puree vs. Pumpkin Pie Filling

This is one of the most important ingredient distinctions in the recipe.

Use pure pumpkin puree, not pumpkin pie filling.

Pure pumpkin puree contains pumpkin without added sugar or spices.

Pumpkin pie filling, sometimes labeled pumpkin pie mix, already contains sweeteners and seasonings.

Since this recipe includes its own sugar, vanilla, and pumpkin pie spice, using pumpkin pie filling would change the sweetness and flavor.

Look for a can labeled 100% pure pumpkin.

Why Add Pumpkin Pie Spice?

Pumpkin puree provides the actual pumpkin flavor, but pumpkin pie spice gives the casserole those familiar warm fall notes.

The spice blend typically contains cinnamon, ginger, nutmeg, and sometimes cloves or allspice.

Combined with vanilla, brown sugar, and buttery brioche, it makes the entire casserole taste like fall.

And because we’re adding pumpkin pie spice to both the custard and the streusel, that flavor carries through every bite.

Can I Make Homemade Pumpkin Pie Spice?

Absolutely.

If you don’t have a jar of pumpkin pie spice, you can make your own blend using ground cinnamon, ginger, nutmeg, and cloves or allspice.

Just remember that cinnamon should generally be the dominant flavor, with smaller amounts of the stronger spices.

Use your homemade blend in the same quantities listed in the recipe.

Why Is My Pumpkin French Toast Casserole Soggy?

French toast casserole should be soft and custardy in the center, but it shouldn’t be wet or undercooked.

If yours turns out soggy, there are a few possible reasons.

The Bread Was Too Fresh

Extremely soft, fresh bread can break down more easily when soaked.

Slightly stale or dried brioche tends to hold its structure better.

It Needed More Baking Time

Ovens vary, and the exact depth of your casserole can affect cooking time.

Make sure the center is fully set before removing it from the oven.

The Bread Wasn’t Distributed Evenly

If too much bread is concentrated in one area, the custard may collect elsewhere in the dish.

Spread the bread cubes evenly and gently press them into the pumpkin mixture before baking.

It Was Sliced Too Soon

Let the casserole rest for approximately 10 minutes after baking.

This helps the custard settle and makes the finished casserole easier to serve.

How to Get a Crispy Streusel Topping

That buttery brown sugar pecan topping is one of the best parts of this recipe.

For the best results, keep these tips in mind.

Mix until crumbly. You want distinct crumbs rather than a completely smooth paste.

Distribute it evenly. Make sure every section of the casserole gets some topping.

Bake uncovered at the end. Removing the aluminum foil during the final 15–20 minutes allows the streusel to become golden and lightly crisp.

Don’t overbake. The topping should be golden brown, but the casserole underneath should still be soft and moist.

Can I Leave Out the Pecans?

Yes.

If you don’t like pecans or need to make the recipe without nuts, you can leave them out.

The brown sugar streusel will still be delicious.

You’ll lose some of the nutty flavor and crunch, but the topping will still provide a sweet, buttery contrast to the pumpkin French toast.

Can I Add Chocolate Chips?

Absolutely.

Chocolate and pumpkin are a delicious combination.

If you want to turn this into more of a dessert-style breakfast, sprinkle some chocolate chips among the bread cubes before adding the custard.

I would start with a modest amount because the streusel already adds plenty of sweetness.

Can I Add Cream Cheese?

You can add small dollops of softened, sweetened cream cheese between the bread cubes for a pumpkin cheesecake-inspired variation.

That would make the casserole even richer.

For the original version, though, I love how the pumpkin custard and brown sugar pecan streusel work together without needing additional filling.

Can I Use Non-Dairy Milk?

You can experiment with unsweetened non-dairy milk such as oat milk or coconut milk.

Keep in mind that different milk alternatives have different amounts of fat and varying flavors.

Whole milk gives this recipe a rich, familiar French toast texture.

If using a non-dairy alternative, choose an unsweetened variety so you don’t unintentionally add extra sugar.

Can I Use Heavy Cream?

You can substitute some of the milk with heavy cream if you prefer a richer custard.

However, brioche, eggs, pumpkin puree, and the buttery streusel already make this casserole quite rich.

I find milk works beautifully.

What to Serve With Pumpkin French Toast Casserole

This pumpkin French toast bake is sweet and comforting, so I like serving it with savory breakfast dishes or fresh fruit.

Some great options include:

• Crispy bacon
• Breakfast sausage
• Scrambled eggs
• Fresh berries
• Sliced apples
• Greek yogurt
• Warm maple syrup
• Hot coffee
• Apple cider

For a holiday brunch, you can place the casserole in the center of the breakfast table and surround it with your family’s favorite breakfast sides.

Perfect for Thanksgiving Morning

If you’re anything like me, Thanksgiving morning is not the time you want to be making a complicated breakfast.

There’s already enough cooking happening later in the day.

That’s exactly why I love an overnight French toast casserole.

You can assemble everything on Wednesday evening and refrigerate it overnight.

On Thanksgiving morning, sprinkle on the streusel and bake.

While it’s in the oven, you can enjoy your coffee, spend time with your family, or get started on the rest of your holiday cooking.

And because it uses real pumpkin, pecans, brown sugar, and warm spices, it fits the holiday perfectly.

A Cozy Fall Weekend Breakfast

You definitely don’t need a holiday as an excuse to make this recipe.

Sometimes a chilly Saturday morning is reason enough.

There’s something so comforting about the smell of pumpkin spice, vanilla, and brown sugar filling the kitchen.

Serve it warm with maple syrup and a cup of coffee, and you’ve got a breakfast that feels a little special without requiring much extra effort.

Can I Prepare the Streusel Ahead of Time?

Yes!

In fact, if you’re making the overnight version, I recommend preparing the streusel separately.

Mix the flour, brown sugar, white sugar, pumpkin pie spice, pecans, and melted butter until crumbly.

Cover the bowl and refrigerate overnight.

The next morning, sprinkle it over the casserole just before baking.

Keeping the topping separate prevents it from sitting in the wet pumpkin custard overnight, helping preserve its crumbly texture.

Can I Freeze Pumpkin French Toast Casserole?

Yes.

For the easiest option, bake the casserole first and let it cool completely.

Cut it into individual servings and transfer them to freezer-safe containers.

Freeze for up to approximately 2–3 months for the best quality.

Thaw overnight in the refrigerator and reheat until warmed through.

Freezing individual portions is especially convenient when you want a quick fall breakfast without making an entire casserole again.

How to Store Leftovers

Because this recipe contains eggs and milk, leftovers should be refrigerated.

Let the casserole cool slightly, then transfer it to an airtight container or cover the baking dish tightly.

Refrigerate promptly and enjoy within 3–4 days.

How to Reheat Pumpkin French Toast Casserole

For individual servings, the microwave is the easiest option.

Heat until warmed through.

If you’re reheating several servings, place them in an oven-safe baking dish and warm them in the oven at approximately 325°F, covered loosely to prevent drying out.

If you want the streusel to become slightly crisp again, uncover the casserole near the end of reheating.

Add fresh maple syrup just before serving.
