Sweet potatoes are the star here, so grab the orange variety—they’re naturally sweeter and hold up better to roasting. Trader Joe's and Whole Foods carry the best quality, but any grocery store’s organic section will work. Look for firm potatoes with smooth skins—none of that soft, wrinkly stuff. Peeled and cubed, they’ll roast until tender enough to fall apart, creating that signature sticky texture. Pro tip: cube them evenly so they cook at the same rate. I always roast mine at 400°F for 30 minutes before mixing with the other ingredients—this ensures perfect tenderness without drying out.
No spiced rum? Apple cider or bourbon works in a pinch, but the rum adds that caramel depth that makes this casserole special. The celery crown topping is where the magic happens—fresh celery is a must (the crunch is non-negotiable). If you can’t find a bunch, Trader Joe’s frozen chopped celery thaws perfectly for this. For the cream cheese layer, full-fat is essential—it melts into that luscious, rum-infused creaminess. Want extra crunch? Toast the pecans in a dry pan for 3-4 minutes until fragrant. And if you’re feeling fancy, swap the granulated sugar for turbinado for a crunchy texture.
This casserole reheats like a dream—just cover it with foil and pop it in the oven at 350°F for 20-25 minutes. Leftovers keep for 4-5 days in the fridge, but honestly, they’ll disappear faster than that. For make-ahead magic, assemble the casserole the night before and let it sit overnight—flavors meld even better. The celery crown topping can be prepped ahead and stored in the fridge for 2 days, so you’re not scrambling on baking day. And if you’re serving a crowd, double the recipe—it’s that good.

Step-by-step instructions for sticky fingers sweet potato casserole
Here's how to transform humble sweet potatoes into a showstopping casserole with irresistible textures.
🍳 Step 1: Roast Sweet Potatoes Until Fork-Tender
Preheat your oven to 400°F and line a large baking sheet with parchment paper. Toss the 3 lbs peeled and cubed orange sweet potatoes with 2 tablespoons olive oil (not listed but essential for roasting), 1 teaspoon salt, and 1 teaspoon cinnamon. Spread them in a single layer—they need room to crisp.
Roast for 25-30 minutes until the edges are golden brown and they pierce easily with a fork. You want them tender but not mushy—this creates the perfect base for that sticky texture. Here's the thing—don't overcrowd the pan or they'll steam instead of roast. If needed, work in batches.
👨🍳 Step 2: Prepare the Celery Crown Crunch Topping
While the sweet potatoes roast, trim the celery stems into 1-inch pieces, keeping the leafy tops intact. In a small bowl, whisk together 0.5 cup all-purpose flour, 0.5 teaspoon salt, and 0.25 teaspoon cinnamon. Toss the celery pieces in this mixture until evenly coated.
Spread them on a separate baking sheet and bake at 375°F for 10-12 minutes until golden and crisp. Watch them closely—they burn quickly but develop that perfect crunch we're after. Here's where it gets fun—save these crispy crowns for topping later.
🥘 Step 3: Make the Spiced Rum Cream Cheese Layer
In a medium saucepan, melt 0.5 cup unsalted butter over low heat. Whisk in 0.5 cup brown sugar, 0.25 cup granulated sugar, and 0.5 teaspoon ground nutmeg until combined. Add 0.5 cup spiced rum and bring to a gentle simmer for 2 minutes—you'll smell that warm rum aroma filling your kitchen.
In a separate bowl, beat the 8 oz cream cheese until smooth, then mix in the 0.25 cup heavy cream and 1 teaspoon vanilla extract. Slowly pour the warm sugar mixture into the cream cheese while whisking constantly. This is the moment that matters—the sauce should be thick but pourable. If it's too thick, add 1 tablespoon cream to loosen it.
🔥 Step 4: Assemble and Bake the Casserole
Transfer the roasted sweet potatoes to a 9x13-inch baking dish. Spread the warm cream cheese mixture evenly over the top, then sprinkle with the remaining 1 teaspoon cinnamon and 0.5 cup chopped pecans. Here's the trick—press down gently on the pecans so they stick to the top layer.
Bake at 350°F for 20-25 minutes until the top is golden and bubbly. The edges should pull away slightly from the pan—that's your signal it's ready. Real talk: your oven might run hot, so start checking at the 20-minute mark. If it browns too quickly, tent with foil.
🍽️ Step 5: Top with Celery Crowns and Serve Warm
Remove from the oven and immediately sprinkle the crispy celery crowns over the top. The contrast between the creamy sweet potato layer and the crunchy celery is what makes this casserole legendary. Let it sit for 5 minutes so the crowns get slightly softened by the steam.
Serve warm with a dollop of whipped cream or vanilla ice cream. The first bite delivers that perfect combination of creamy, spiced sweet potato, rich rum cream cheese, and crunchy celery crown. Don't skip the celery topping—it's what makes this dish unforgettable!
Pro Tips For Making Sticky Fingers Sweet Potato Casserole
- Roast Potatoes First: DESCRIPTION: Peel and cut sweet potatoes into even ½-inch cubes, then roast them at 400°F (200°C) for 15 minutes before mixing with the butter and sugars. This jumpstarts the caramelization—no soggy centers here, just tender cubes that soak up the sticky goodness.
- Use Cold Butter: DESCRIPTION: Cut your unsalted butter into small cubes and toss it with the roasted potatoes before adding the sugars. The cold butter melts slower, creating pockets of richness that prevent the topping from turning into a syrup puddle.
- Skip the Overmixing: DESCRIPTION: Once you fold in the sugars and cinnamon, stop stirring the second everything clumps. Overworking it turns the casserole into a paste—you want those buttery, caramelized bits to stay intact. Just press gently and let the oven do the work.
- Cover Early, Uncover Late: DESCRIPTION: Tent the dish with foil for the first 20 minutes to trap steam, then remove it for the last 10-15 minutes. This ensures a crispy, sticky top without a gummy middle—like a caramelized hug for your sweet potatoes.
Best sauces and condiments for these flavors
Caramelized Maple Syrup Glaze
This rich glaze takes your casserole to next-level decadence. Simmer ½ cup pure maple syrup with 2 tablespoons unsalted butter and 1 teaspoon cinnamon for 3-4 minutes until thickened.
Brush this warm glaze over the baked casserole just before serving—it adds a sticky, amber finish that complements the celery crown perfectly. 🍁
Brown Butter Pecan Streusel
Swap the plain pecans for a brown butter streusel that adds nutty depth. Melt ¼ cup butter until nutty brown (about 5 minutes), then mix with ½ cup chopped pecans, 2 tablespoons flour, and 2 tablespoons brown sugar.
Sprinkle this over the cream cheese layer before baking for a crunchy, buttery contrast.
Spiced Rum Cream Cheese Swirl
For a marbled effect, divide the cream cheese mixture in half. Spread one portion over the sweet potatoes, then dollop spoonfuls of the remaining mixture on top.
Use a knife to swirl gently—this creates beautiful ribbons of rum-infused cream cheese throughout. The visual impact makes it feel extra special for holiday tables.
Honey Butter Drizzle
Finish with a simple but elegant drizzle: mix 2 tablespoons melted butter with 1 tablespoon honey and a pinch of salt. Drizzle over the baked casserole just before serving—this adds a delicate sweetness that balances all the spices. The honey butter pairs beautifully with the celery crown's crunch.
Caramelized Onion Topping
For a savory-sweet twist, caramelize 1 cup thinly sliced onions in 1 tablespoon butter for 15-20 minutes until deep golden. Fold these into the cream cheese mixture before spreading over the sweet potatoes. The onion adds complexity that elevates the dish beyond traditional sweet potato casseroles.
Vanilla Bean Infusion
Elevate the cream cheese layer by infusing it with vanilla. Split a vanilla bean, scrape the seeds, and add both seeds and pod to the warm sugar mixture.
Let steep for 5 minutes before mixing into the cream cheese. This adds floral notes that complement the spiced rum beautifully—trust me, it makes all the difference. ✨

Frequently asked questions
Why does this casserole have "sticky fingers"?
The signature texture comes from perfectly roasted sweet potatoes that become tender but still hold their shape slightly—creating that irresistible pull-apart quality. The spiced rum cream cheese layer adds richness that makes every bite cling to your fingers. Pro tip: Roasting the potatoes at 400°F for 25-30 minutes ensures they're fork-tender but not mushy.
Can I make this ahead of time?
Assemble the casserole completely (even with the celery crown topping) up to 24 hours ahead and refrigerate. Bake it straight from the fridge, adding 10-15 extra minutes at 350°F. The flavors actually deepen overnight. For the celery topping, prep it 2 days ahead and store in an airtight container—it stays crispy!
What if I don't have spiced rum?
No worries! Substitute with ½ cup apple cider or bourbon for similar depth, or use ½ cup orange juice for a lighter flavor. The key is the warm liquid that blends with the cream cheese—just omit the rum's caramel notes. For extra warmth, add ½ teaspoon cinnamon to the cream cheese mixture.
How do I keep the celery crown topping crispy?
Bake the celery topping separately at 375°F for 10-12 minutes until golden, then immediately transfer to a paper towel-lined plate. This draws out excess moisture. When adding to the baked casserole, sprinkle it on just before serving—this way, it stays crunchy instead of soggy. For extra insurance, bake the celery with a pinch of salt on the tray to absorb moisture.
Can I make this gluten-free?
Yes! Replace the all-purpose flour in the celery topping with ½ cup gluten-free flour blend or ½ cup ground almonds. For binding, add 1 tablespoon cornstarch to the celery mixture. The cream cheese layer and sweet potatoes are naturally gluten-free, so the only adjustment is the topping. Test the celery's crispiness—it may need an extra minute in the oven.
