The Story Behind the Recipe

Long before kids or blogging, my husband Trent and I chased our dream of becoming musicians out West.

While living there, I worked for a few celebrities and was invited to a stunning Thanksgiving feast catered by a professional chef.

The one dish everyone raved about? This sweet potato casserole.

It was rich, sweet, and absolutely decadent — and I’ve been making it every year since.

And now, almost 15 years later, I’m sharing this recipe with you.

Ingredients You’ll Need

For the Sweet Potato Layer:

• 3 cups cooked sweet potatoes (baked or microwaved, cooled)
• 2 large eggs, lightly whisked
• 1 Tbsp vanilla extract
• 1/2 cup white sugar

For the Pecan Crumble Topping:

• 1 cup brown sugar
• 1/2 cup flour
• 1/3 cup butter, softened (not melted!)
• 1/4 to 1/2 cup pecan pieces, to taste

How to Make Sweet Potato Casserole with Pecan Topping

#1 Bake the Sweet Potatoes

Preheat oven to 350°F. Wash and bake sweet potatoes until fork tender, about 45–60 minutes.

Shortcut: Microwave them if you’re short on time.

Once cooled, scoop out the flesh and mash lightly — keep a bit of texture!

TIP: You’ll need 3 cups of mashed sweet potato (about 2-3 large potatoes)

#2 Make the Sweet Potato Filling

In a large bowl, combine:

• Mashed sweet potatoes
• Lightly beaten eggs
• Vanilla
• Sugar

Stir until just blended.

Spread into a greased 9×13-inch casserole dish.

#3 Make the Pecan Crumble Topping

In a separate bowl, mix:

• Brown sugar
• Flour
• Softened butter (not melted!)

Stir until crumbly, then gently fold in pecans. I usually use 1/4 cup broken pecan pieces, but feel free to add more if you love that crunch!

Sprinkle the crumble topping evenly over the sweet potato layer.

#4 Bake

Bake uncovered at 350°F for 45 minutes, or until the top is golden brown and slightly bubbling around the edges.

Pro tip: If the topping browns too fast, loosely tent with foil during the last 10 minutes.

FAQs

Can I use canned sweet potatoes?
I don’t recommend it. Whole sweet potatoes or real yams are definitely needed for this dish. Canned sweet potatoes are too smooth and may result in a runny mixture.

Can I make this ahead of time?
Yes! Prep the sweet potato filling and topping separately. Refrigerate both up to 2 days ahead. Bring to room temp, assemble, and bake before serving.

Do I have to use pecans?
Nope! Walnuts work too, or skip the nuts entirely for picky eaters.

Tips for Success

• Don’t puree the sweet potatoes — a potato masher gives the best texture.
• Use real butter, not margarine, for that rich crumble.
• Serve warm or room temp — and it reheats beautifully for leftovers!
• Skip the marshmallows — Mini marshmallows are on lots of sweet potato recipes, but trust me – the brown sugar streusel is sweet enough!
• Make-ahead tips: The best thing about this recipe is that you can prep most of it 1-2 days ahead of time. Just keep the creamy sweet potato filling and crumble topping separate in an airtight container then bring to room temperature before assembling and baking.
• This the best recipe for delicious leftovers! I love reheating up leftovers the next day and this dish really does hold up well for a few days!

Perfect Pairings

This sweet potato casserole pairs perfectly with:

• Roasted turkey or ham
• Herb stuffing
• Pork tenderloin
• Baked salmon
• Or even a cozy Sunday chicken dinner

And just look at this spread!

The pecan streusel topping is the star of this dish!

This simple sweet potato casserole with pecans is the one dish my family asks for every holiday season — and I’m so excited to share it with yours.

And don’t save this for just the holiday table or Thanksgiving day! This is such a great dish that would work well in your Sunday dinners rotation or any other special occasions. This would pair well with cooked salmon, roasted chicken, pork tenderloin or baked ham!

It’s warm, cozy, nostalgic, and absolutely delicious.

I hope it becomes a staple at your table too.
