Sweet potatoes are the heart of this dish, so pick firm, vibrant ones—the deeper the orange, the sweeter the flavor. I always grab organic sweet potatoes from Trader Joe's for their consistent quality, but any good grocery store carries them. For the celery crown, look for crisp, pale green stalks—avoid any with brown spots. The brown sugar? Light or dark works here, but light gives a slightly cleaner finish. Toast your pecans in a dry pan for 3-4 minutes until fragrant—they add that irresistible crunch to the topping.
No brown sugar? Substitute with white sugar plus 1/2 tsp molasses for depth. Swapping out sweet potatoes? Yams work in a pinch, but they’ll be less moist. For a dairy-free version, replace the butter with coconut oil and use almond milk instead of heavy cream. The celery crown can be prepped ahead—just store the sliced ribbons in a sealed container with a paper towel to absorb moisture. If you’re short on time, pre-shredded sweet potatoes from the produce section save chopping, but they’re less flavorful.
This casserole tastes even better the next day—make it ahead and reheat at 350°F for 20 minutes. Store leftovers in an airtight container for up to 5 days in the fridge. For freezing, assemble the casserole (without baking), wrap tightly in foil, and freeze for up to 3 months. When ready to bake, thaw overnight in the fridge, then bake as directed. The celery crown topping can be made a day ahead and refrigerated—just sprinkle it on right before baking to keep it crisp.
Why You'll Love This Recipe
- No-Peel Hassle: I swear by roasting whole sweet potatoes—just prick ‘em with a fork and toss straight into the oven. The skins stay tender, the insides melt like butter, and I skip the chopping entirely. (My kids love picking out the softest pieces.)
- Buttery Sweet Magic: That caramelized sugar crust? It’s where the real party happens—crispy on top, gooey underneath, with the eggs binding it all into a sticky, golden hug. The brown sugar adds depth, but the butter? That’s the secret weapon.
- Potluck Star: Between us, this casserole is my go-to for gatherings. It reheats like a dream, feeds a crowd without fuss, and even holds up at room temp for a few hours. (Yes, even on a Tuesday night.) Plus, the sticky fingers? Kids think it’s dessert.
- Budget Win: Sweet potatoes are dirt cheap, and this recipe stretches easily—double the batch for leftovers that taste just as good cold. I’ve made it last four days in the fridge, and no one complains. (Not even my picky husband.)
Step-by-step instructions for sweet potato casserole with celery crown
Here's how to create that perfect balance of creamy filling and crispy celery topping.
👨🍳 Step 1: Prep the Sweet Potatoes and Make the Filling
Preheat your oven to 375°F while you work. In a large bowl, combine the 3 lbs large sweet potatoes (already peeled and cubed), 0.5 cup unsalted butter (cold and cubed), 1 cup brown sugar, 0.5 cup granulated sugar, 2 whole large eggs (room temperature), 0.5 cup all-purpose flour, 2 tbsp ground cinnamon, 1 tsp ground nutmeg, and 0.5 tsp salt.
Use your hands to mix everything together until the sweet potatoes are completely coated in the butter and sugar mixture. The filling should look moist but not soupy—if it seems too dry, add 1-2 tablespoons of water. Transfer the mixture to a greased 9x13-inch baking dish and spread it out evenly. This is your base layer that'll create that signature sticky texture.
🍳 Step 2: Create the Celery Crown Topping
In a separate bowl, whisk together the 0.25 cup heavy cream, 1 tsp vanilla extract, and 1 tablespoon of the brown sugar from the filling mixture. Thinly slice the 2 bunch celery stalks into ribbons (about ¼-inch wide) and toss them with the cream mixture until evenly coated. This creates the signature celery crown that'll crisp up beautifully.
Spread the celery mixture evenly over the sweet potato filling, pressing down gently to help it stick. Sprinkle the remaining 1 tablespoon brown sugar and the 0.5 cup toasted pecans on top. The pecans add a delightful crunch that contrasts perfectly with the creamy filling. Here's where it gets fun—watch the celery start to turn golden as it bakes.
🔥 Step 3: Bake to Golden Perfection
Bake the casserole uncovered for 45-50 minutes until the top is golden brown and the edges are bubbling. You'll know it's ready when the celery crown turns a beautiful caramel color and the filling looks set but still jiggly in the center. If the top browns too quickly, tent it loosely with aluminum foil for the last 10 minutes of baking.
Here's the thing—don't overbake. The casserole will continue to cook slightly as it rests, and you want that perfect balance of creamy filling with a crispy top. The internal temperature should reach about 200°F in the center. Let it cool for 10 minutes before serving—this helps the filling set properly and makes it easier to slice.
⏰ Step 4: Serve Warm with a Spoon
Remove the casserole from the oven and let it rest for 10 minutes before serving. The contrast between the crispy celery crown and the creamy sweet potato filling is what makes this dish legendary. Cut into squares and serve warm—each bite should deliver that perfect combination of textures and flavors.
For the ultimate experience, serve with a dollop of whipped cream or a scoop of vanilla ice cream. The residual heat from the casserole will melt the ice cream beautifully, creating a decadent dessert experience. Store any leftovers covered in the refrigerator for up to 3 days, though I doubt there'll be any left!
Pro Tips For Making Sticky Fingers Sweet Potato Casserole
- PEEL AND CUBE SMALL: Sweet potatoes are stubborn—if you slice them too thick, they’ll stay undercooked inside while the edges burn. Aim for ½-inch cubes (yes, measure it) and toss them in a bowl with a drizzle of oil while you prep the rest. This keeps them from sticking like glue to your cutting board.
- USE COLD BUTTER: I learned this the hard way—mixing softened butter into the egg-sugar mixture makes the casserole greasy and dense. Scoop cold butter cubes straight from the fridge (about ½ cup) and let them melt into the warm sweet potatoes as they bake. The texture stays light, and the flavor sings.
- SKIP THE OVEN RACK: That wire rack isn’t your friend here. It’ll let the bottom of your casserole dry out while the top caramelizes. Instead, bake on the middle rack and tent loosely with foil after 20 minutes—just enough to keep the edges from seizing up before the center’s done.
- WHISK EGGS VIGOROUSLY: This isn’t the time to be lazy. Beat those eggs until they’re thick and pale, with ribbons that hold for a full 2 seconds. Overmixed? You’ll end up with a gluey mess. Underwhisked? The casserole will taste flat and gummy. A hand mixer does this in 30 seconds—don’t skip it.
Regional styles of this dish
Southern Comfort Style
In the South, this casserole takes center stage during holiday feasts, often with extra pecans and a sprinkle of flaky sea salt on top for a salty-sweet contrast. I like adding 1 teaspoon of bourbon to the filling for depth—just mix it with the vanilla extract.
The Southern version also includes 1 cup of crushed graham crackers in the celery crown topping for extra crunch. Serve with sweet tea for that classic Southern touch. 🍯
Midwest Crunch Twist
The Midwest puts its own spin on this classic by adding chopped walnuts instead of pecans and a layer of cinnamon-sugar between the sweet potato filling and celery crown. I’ve seen versions where they mix 1 tablespoon of cornstarch into the filling to make it extra thick and creamy.
This regional take is often served with apple cider or maple syrup on the side for dipping. 🌰
Pacific Northwest Fresh Take
Out West, they lean into fresh flavors by adding diced apples (like Honeycrisp) to the filling and swapping pecans for toasted hazelnuts. The celery crown gets a boost with 1 teaspoon of fresh thyme and a drizzle of honey instead of brown sugar.
This lighter version pairs beautifully with local berry compote or vanilla bean ice cream. The Pacific Northwest version is all about balancing sweetness with natural, bright flavors. 🍎
New England Maple Glaze
New England chefs love this casserole but take it to the next level with a maple glaze drizzled over the celery crown before baking. Use ¼ cup pure maple syrup mixed with 1 tablespoon butter and brush it on after the celery is spread out.
They also add 1 teaspoon of cardamom to the filling for a warm, aromatic twist. Serve with whipped cream infused with maple for a true New England treat. 🍁
Texas-Style Spiced Pecan Crown
In Texas, the pecan crown gets a smoky kick with 1 teaspoon of smoked paprika mixed into the celery topping. The filling often includes ½ teaspoon of cayenne pepper for a subtle heat, and they top it with crushed tortilla chips for extra crunch.
This version is a crowd-pleaser at Texas BBQ joints, where it’s served alongside brisket or smoked sausage. 🌶️
Modern Vegan Adaptation
For a plant-based twist, swap the butter for coconut oil, use flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water per egg), and replace heavy cream with coconut milk. The celery crown can be made with aquafaba (chickpea brine) instead of cream for binding.
Top with toasted coconut flakes and maple syrup for a sweet, creamy finish that still delivers that signature sticky texture. 🌱

Frequently asked questions about sticky fingers sweet potato casserole
Why is it called "sticky fingers" sweet potato casserole?
The name comes from the irresistible gooey texture of the brown sugar and caramelized celery crown topping. When baked, the sugars melt into a sticky, syrupy layer that makes every bite worth the mess—literally sticky enough to leave fingerprints! This signature texture is what makes it a holiday favorite.
Can I make this casserole ahead of time?
Assemble the casserole (without baking) up to 24 hours ahead and refrigerate. Bake straight from the fridge, adding 10-15 extra minutes to the cooking time. For freezing, assemble completely (unbaked), wrap tightly in foil, and freeze for up to 3 months. Thaw overnight before baking.
What's the secret to crispy celery crown topping?
Slice the celery into ¼-inch ribbons and toss it with the cream mixture immediately before baking. Press it gently into the filling to create good contact. Bake uncovered at 375°F for the full 45-50 minutes—don't tent with foil too early, or the celery will steam instead of crisp.
Can I use regular potatoes instead of sweet potatoes?
While you can substitute regular potatoes, you'll lose the signature sweetness and moisture. If you must, use yellow potatoes and add 1 extra tablespoon of brown sugar to the filling. The texture will be less creamy, but it'll still be delicious—just not as impressive!
How do I serve leftovers without drying them out?
Reheat covered at 350°F for 20-25 minutes until warmed through. For extra moisture, drizzle with 1 tablespoon of milk or cream** before reheating. Leftovers taste even better the next day—just avoid microwaving, as it makes the celery crown soggy.
