This sweet potato casserole recipe with orange zest transforms a classic holiday side into something vibrant and unforgettable. The bright citrus twist cuts through the richness of the creamy spiced base, creating a perfect balance of sweet, spicy, and tangy flavors that elevate any dinner table.

I developed this version after years of testing, and the orange zest makes all the difference—it’s the secret weapon that keeps this dish from feeling heavy or one-note.

The recipe starts with tender sweet potatoes, roasted until perfectly soft and infused with cinnamon, nutmeg, and just a touch of salt. Then comes the magic: folding in fresh orange zest for that bright, zesty kick that brightens every bite.

Topped with a buttery, crumbly mixture of breadcrumbs, brown sugar, and melted butter, this casserole develops a golden, crispy crust while staying creamy underneath—a texture combination that’s impossible to resist.

What makes this version stand out is how the orange zest transforms an ordinary side dish into something special. The citrus notes complement the warm spices beautifully, creating a flavor profile that’s both comforting and exciting.

It pairs wonderfully with roasted meats, mashed potatoes, or even as a standalone dessert-like side for a cozy meal. The best part? It’s a crowd-pleaser that feels restaurant-quality but is simple enough for any home cook to master.

Let’s get started on creating a side dish that will have everyone asking for seconds.

Ingredients for sweet potato casserole recipe with orange zest

Six ingredients transform classic sweet potatoes into a vibrant citrus-spiced masterpiece—creamy, crispy, and unforgettable.

The orange zest is non-negotiable here—fresh is essential—so grab a bright, organic orange from Whole Foods or your local market. The sweet potatoes should be firm and vibrant; Yukon Golds work best for their natural sweetness. For the pecans, Trader Joe's has the best-priced pre-chopped pieces, but toast them yourself for extra flavor. The cinnamon and nutmeg should be freshly ground—Penzeys spices are my go-to for that authentic warmth. Don’t skip the orange juice; it balances the sweetness perfectly and keeps the dish from tasting one-note.

No fresh orange zest? Substitute 1 tbsp bottled orange zest (like Felippo Berio), but it won’t have the same brightness. Running low on pecans? Walnuts or almonds work in a pinch, though they’ll change the texture slightly. The heavy cream can be swapped for half-and-half if you’re watching fat, but trust me on the full-fat version. For the sweet potatoes, if you can’t find Yukon Golds, Beauregard is the next best thing. And if you’re out of brown sugar, white sugar plus 1 tsp molasses mimics the depth.

This casserole reheats like a dream—350°F for 20-25 minutes until bubbly. Store leftovers in an airtight container for up to 4 days; it actually tastes better the next day as flavors meld. For make-ahead convenience, assemble everything (except the topping) up to 24 hours ahead and refrigerate. The topping can be mixed and stored separately for up to 3 days. Freeze the fully baked casserole for up to 3 months—just thaw overnight in the fridge before reheating.

Step-by-step instructions for sweet potato casserole with orange zest

Here's how to create a velvety, citrus-kissed sweet potato masterpiece that's creamy, spiced, and topped with a crunchy pecan crust.

Preheat your oven to 375°F. Peel and cube the 3 lbs sweet potatoes into ½-inch pieces for even cooking. Spread them in a single layer on a rimmed baking sheet and bake for 25-30 minutes until they're fork-tender with no resistance. You'll know they're done when the edges start to soften and the centers yield slightly to pressure.

While they cook, I like to give them a head start by microwaving them for 5 minutes first—this cuts down on oven time and ensures even tenderness. Once they're soft, transfer them to a large mixing bowl and let them cool slightly before handling. The residual heat will help incorporate the spices more evenly later.

In the bowl with the warm sweet potatoes, add the 0.25 cup granulated sugar, 2 tbsp orange zest, 0.25 cup orange juice, 0.5 cup heavy cream, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 0.5 tsp salt, and 0.25 tsp ground black pepper. Using a potato masher or wooden spoon, mash everything together until you achieve a smooth, lump-free texture with just a few slight ridges—this gives that perfect creamy consistency without being too thick.

The orange zest and juice will brighten the natural sweetness of the sweet potatoes while the spices create that warm, comforting flavor profile. Taste as you go—you might want to adjust the sweetness or spice level here. If it needs more depth, a pinch of cinnamon or nutmeg makes all the difference. Let the mixture cool for 5 minutes before transferring to a greased 9x13-inch baking dish.

In a separate bowl, combine the 1 cup all-purpose flour, 0.5 cup brown sugar, and 0.75 cup cold cubed unsalted butter. Using your fingers or a fork, work the butter into the flour mixture until it resembles coarse crumbs with some pea-sized butter pieces remaining—this ensures a crispy, not greasy, topping. Stir in the 1.5 cups pecan pieces until evenly distributed.

Here's the thing—don't overmix. You want the butter to stay in chunks so it melts and creates steam during baking, which helps crisp the topping. Spread this mixture evenly over the sweet potato filling in the baking dish, pressing down gently to ensure good contact. The pecans will add a delightful crunch that contrasts beautifully with the creamy base.

Transfer the baking dish to a preheated 350°F oven and bake for 35-40 minutes until the topping is deep golden brown and the edges are bubbling slightly. The center should still be warm and slightly jiggly—this indicates it's creamy, not rubbery. If the topping browns too quickly, tent it loosely with aluminum foil to prevent over-browning while it finishes baking.

I've found that the first 20 minutes are critical—this is when most of the cooking happens. After that, it's just about monitoring the color. When you pull it out, let it rest for 10 minutes before serving. This resting period allows the filling to set slightly, making it easier to cut clean slices without losing that perfect creamy texture.

Once rested, slice into 6 equal portions for your 6 servings. The contrast of the warm, spiced sweet potato filling with the crispy pecan topping is what makes this dish truly special. For an extra touch, I like to garnish each serving with a sprinkle of additional orange zest just before serving—it adds a fresh, citrusy aroma that complements the warm spices perfectly.

This casserole tastes even better the next day, so it's perfect for meal prep. The flavors meld and deepen as it sits, making every bite even more comforting. Serve with a dollop of whipped cream or a scoop of vanilla ice cream for an indulgent dessert experience that's anything but heavy.

Southern Comfort

In the American South, sweet potato casseroles are holiday staples, and this orange zest version puts a modern twist on tradition. I remember my grandmother's classic version with marshmallows, but adding 2 tbsp orange zest brightens the dish while keeping that familiar Southern warmth.

The pecan topping is a nod to Southern pecan pie traditions, and using brown sugar instead of white adds depth that feels right at home. 🍠

For an even more authentic touch, swap the pecans for chopped candied pecans—toss 1.5 cups pecans with 2 tbsp honey and 1 tsp cinnamon, then bake at 300°F for 15 minutes before mixing into the topping.
