Ingredients for sweet potato casserole recipe video
Here’s what you need for that showstopping sweet potato casserole with crispy celery crown—holiday magic in one dish!
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 3 lbs | Peeled and cubed evenly |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for crispy topping |
| Celery Stalks 🥬 | 1 lb | Thinly sliced for lattice |
| Brown Sugar 🍚 | 1 cup | Packed, for sweetness balance |
| Granulated Sugar 🍚 | ½ cup | For caramelization |
| Large Eggs 🥚 | 2 whole | Beaten for binding |
| All-Purpose Flour 🌾 | 1 ½ cups | For crispy texture |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌶️ | 1 ½ tsp | Freshly grated for warmth |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Vanilla Extract 🍯 | 1 tsp | Pure vanilla preferred |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Pecans (optional) 🌰 | 1 cup | Chopped for extra crunch |
The sweet potatoes are the heart of this dish, so pick firm, vibrant orange ones—those with no soft spots or bruises. I always grab organic sweet potatoes from Trader Joe’s because they’re consistently sweet and hold their shape. For the celery, freshness is key—look for stalks that are crisp and pale green, not yellowed or wilted. The celery crown technique relies on thin, even slices, so a sharp knife (or mandoline if you’re fancy) makes all the difference. Pro tip: Soak the celery in cold water for 10 minutes before slicing to keep it crisp during prep.
No butter? Coconut oil or vegan butter works in a pinch, though the flavor won’t be identical. Swapping brown sugar for coconut sugar keeps it vegan-friendly, but the caramelization won’t be as deep. Fresh nutmeg is a game-changer—pre-ground loses its punch fast, so if you’re using that, double the amount. For the celery topping, Panko breadcrumbs can replace flour if you’re gluten-free, but the texture won’t be quite as crispy. And if pecans are out of budget, walnuts or almonds add a similar crunch—just toast them first for extra flavor.
This casserole tastes even better the next day, so make it ahead and refrigerate—just add 10 minutes to baking time. The celery topping stays crispy for up to 3 days if stored in an airtight container, but the filling stays moist for 5 days. For freezing, assemble the dish (without baking), wrap tightly in foil, and freeze for up to 3 months. Bake straight from frozen, adding 20 minutes to the time. Serve warm with vanilla ice cream—trust me, it’s the perfect combo—or drizzle with honey for a sweet touch.

Step-by-step instructions for sweet potato casserole
Here's how to create that perfect balance of creamy sweet potatoes and a golden, crispy celery lattice topping.
👨🍳 Step 1: Prepare the Sweet Potato Filling
Preheat your oven to 375°F while you work. In a large mixing bowl, combine the 3 lbs peeled and cubed sweet potatoes, 1 cup packed brown sugar, 0.5 cup granulated sugar, 2 tsp ground cinnamon, 1.5 tsp ground nutmeg, 0.5 tsp salt, 0.5 tsp black pepper, and 1 tsp vanilla extract. Mix well to ensure every cube gets coated in that warm, spiced sweetness.
In a separate bowl, whisk together the 2 whole large eggs, 0.5 cup heavy cream, and 1.5 cups all-purpose flour until smooth. This creates the perfect binding agent for your filling. Gently fold this egg mixture into the sweet potato mixture until fully combined. The result should be a thick, creamy batter that's ready to bake into tender perfection.
🍳 Step 2: Create the Celery Lattice Topping
While the oven preheats, prepare your celery lattice topping. Thinly slice the 1 lb celery stalks into long, even strips—about ¼-inch thick. You'll want about 12-15 strips total. Arrange half of them in a crisscross pattern on top of the sweet potato mixture in a greased 9x13-inch baking dish, leaving a small border uncovered.
In a small bowl, mix the 0.75 cup cold cubed unsalted butter with 1 cup all-purpose flour until it forms a crumbly texture. Sprinkle this evenly over the celery strips. This butter-flour mixture is what creates that irresistible crispy crown you're after. The cold butter will melt just enough to create a golden, crackly topping while keeping the celery strips tender underneath.
🔥 Step 3: Assemble and Bake to Golden Perfection
Arrange the remaining celery strips in a crisscross pattern over the butter mixture, completing the lattice. If you're using the optional 1 cup chopped pecans, sprinkle them evenly over the top for extra crunch and richness. Transfer the baking dish to the preheated oven and bake for 45-50 minutes.
Here's where the magic happens: the casserole should be bubbling at the edges and the celery lattice should be turning a beautiful golden brown. You'll know it's ready when a knife inserted into the center comes out clean and the top is crispy enough to resist slightly when pressed. If the top isn't golden enough after 45 minutes, broil for 2-3 minutes to crisp it up—just watch it closely to avoid burning.
⏰ Step 4: Rest and Serve Warm
Remove the casserole from the oven and let it rest for 10-15 minutes before serving. This resting time allows the filling to set slightly and makes it easier to slice. The contrast of the warm, creamy sweet potatoes with the crispy celery lattice is what makes this dish truly special.
Slice into perfect squares and serve immediately. Each bite delivers that perfect combination of tender sweet potatoes infused with warm spices and a satisfying crunch from the celery crown. For an extra touch, you can drizzle with a little extra brown sugar or serve with a dollop of whipped cream. This casserole is especially comforting when served with a glass of cold milk or a scoop of vanilla ice cream.
Pro Tips For Making Sweet Potato Casserole Recipe Video
- Peel and Cube Small: Sweet potatoes are stubborn when peeled whole—cut them into 1-inch chunks first, then peel. You’ll save time scrubbing and avoid those awkward half-peeled lumps that always end up in the trash.
- Sauté Celery Until Soft: Don’t just chop celery and toss it in raw—sauté it in butter until the edges turn translucent (about 5 minutes). This removes bitterness and makes the flavor sing in the casserole. (Yes, even if you’re impatient like me.)
- Bake at 375°F, Not Hotter: I used to blast this at 400°F, thinking it’d cook faster, but it’d dry out the edges before the center was done. 375°F gives even browning and lets the sugars caramelize without burning. Trust the oven.
- Mix Butter and Sugars First: Whisk the melted butter with brown and granulated sugar until it’s a smooth paste before adding anything else. This ensures even distribution—no clumpy spots where the butter didn’t blend in. (Your future self will notice the difference.)
Storing and reheating your leftovers
Refrigerator Storage
Store your sweet potato casserole in an airtight container with parchment paper between layers to maintain crispiness. Keep it refrigerated for up to 4 days—the celery lattice stays delightfully crunchy while the filling remains tender. I like using glass Pyrex containers because they’re microwave-safe for quick reheats. Just
Freezer Prep Tips
For long-term storage, assemble the casserole (without baking) in a foil-wrapped baking dish, then freeze for up to 3 months. When ready to bake, thaw overnight in the fridge before adding 10 extra minutes to the baking time. The celery lattice will still crisp beautifully, though you may need to broil for an additional 1-2 minutes to restore its golden color. 🧊
Stovetop Reheat
For the best texture, reheat slices in a lightly oiled skillet over medium-low heat for 5-7 minutes until warmed through. Cover with a lid to trap moisture and prevent drying.
This method preserves that perfect crispy-lattice-meets-creamy-filling contrast. For larger portions, transfer to a baking dish and cover with foil, then bake at 350°F for 20-25 minutes. 🔥
Microwave Shortcut
When short on time, microwave individual portions on 50% power for 2-3 minutes, then stir and continue in 30-second intervals until reaching 165°F. Add a splash of milk or cream to restore moisture if needed.
The celery lattice won’t be as crisp, but the filling stays warm and delicious. Perfect for quick lunches or last-minute servings! ⏰
Reviving Crispiness
If the celery lattice loses its crunch after reheating, sprinkle with a pinch of flour and broil for 1-2 minutes until golden. This quick fix restores that satisfying texture.
For extra flavor, brush the lattice with melted butter before broiling—it adds a rich, nutty depth that pairs perfectly with the sweet filling. 🌟

Frequently asked questions
Can I make this sweet potato casserole ahead of time?
Assemble the casserole (without baking) up to 24 hours ahead and refrigerate it. When ready to bake, add 10 extra minutes to the baking time. For freezing, assemble the unbaked casserole, wrap tightly in foil, and freeze for up to 3 months. Thaw overnight in the fridge before baking. The celery lattice stays crispy when baked straight from frozen, though you may need to broil for 1-2 extra minutes.
How do I keep the celery topping extra crispy?
The secret is in the butter-flour mixture! Use cold cubed butter and sprinkle it evenly over the celery strips before baking. For extra crispiness, broil for 2-3 minutes at the end of baking. If reheating, broil for 1-2 minutes to restore the crunch. A pinch of flour before broiling also helps!
What can I substitute if I don’t have celery?
For a similar texture, try thinly sliced green apples or jicama—they hold their shape and add a subtle sweetness. If you want a more traditional approach, use thinly sliced potatoes or buttered breadcrumbs for a crispy topping. Just note that the flavor will differ slightly from the celery lattice.
Can I make this casserole without eggs?
Yes! Replace the 2 eggs with 2 tablespoons cornstarch mixed with 2 tablespoons water to bind the filling. For extra richness, add 2 tablespoons melted butter or ¼ cup applesauce. The texture will be slightly denser but still delicious. This works well for vegan adaptations too!
Why did my casserole turn out soggy?
Soggy casseroles usually happen from overmixing the filling or underbaking.
