Ingredients for sweet potato casserole recipe with pecan and coconut topping
Six ingredients make this holiday showstopper—creamy sweet potatoes meet tropical pecan-coconut magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 3 lbs | Medium size, peeled and cubed |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for topping |
| Brown Sugar 🍚 | 1 cup | Packed, light or dark |
| Pecans 🥜 | 2 cups | Chopped, toasted for crunch |
| Shredded Coconut 🥥 | 1 cup | Sweetened, unsweetened works too |
| All-Purpose Flour 🌾 | ½ cup | For topping texture |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated for warmth |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Vanilla Extract 🍯 | 1 tsp | Pure vanilla preferred |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Granulated Sugar 🍚 | ¼ cup | For sweet potato layer |
| Evaporated Milk 🥛 | ½ cup | For creamy texture |
The sweet potatoes are the heart of this dish, and orange-fleshed, firm varieties like Beauregard work best. Costco or Trader Joe's usually have pre-peeled, cubed sweet potatoes in the holiday section—grab those for convenience. If you're peeling and cubing yourself, look for potatoes that are heavy for their size. For the topping, raw pecans from the bulk bin toast up better than pre-toasted—just spread them on a baking sheet at 350°F for 8-10 minutes, stirring once. The coconut? Sweetened is traditional, but unsweetened adds a more sophisticated touch if you're feeling fancy.
No pecans? Walnuts or chopped almonds work in a pinch—they won't have the same buttery richness, but they'll add crunch. Running low on coconut? Toasted oats or crushed graham crackers mimic the texture (though not the flavor). The heavy cream can be swapped for half-and-half or coconut milk—just know the texture will be slightly lighter. For the sweet potato layer, if you don't have evaporated milk, whole milk plus 1 tbsp cornstarch (mixed and heated) does the trick. And if you're watching sugar? Reduce the brown sugar to 3/4 cup**—trust me, it still tastes amazing.
This casserole is a prep-ahead dream. Assemble it a day in advance**—the flavors meld beautifully overnight. If you're baking ahead, cover tightly with foil and bake just before serving (about 20 minutes at 375°F). Leftovers? Reheat in a 350°F oven for 15 minutes**—the topping stays crispy if you cover it with foil for the first 10 minutes, then uncover to crisp. Portion into individual ramekins for easy serving—perfect for holiday gatherings where everyone wants their own slice. And if you're feeling extra, a drizzle of honey or caramel sauce** takes it to the next level.

Step-by-step instructions for sweet potato casserole with pecan and coconut topping
This tropical-inspired casserole brings holiday warmth with every bite—crispy topping, creamy filling, and that perfect balance of sweet and nutty.
Prep and Roast the Sweet Potatoes
Preheat your oven to 375°F. Peel and cut the 3 lbs sweet potatoes into 1-inch cubes—uniform size ensures even cooking. Spread them in a single layer on two rimmed baking sheets, leaving space between pieces for air circulation.
Drizzle the sweet potatoes with 2 tablespoons olive oil (not listed but essential for roasting) and toss gently to coat. Roast for 25-30 minutes until tender when pierced with a fork and golden brown at the edges. You want them soft enough to mash easily but not falling apart.
While they roast, here's the thing—don't overcrowd the pan. If they're too close, they'll steam instead of crisp. I like to use two sheets for even browning. Once done, transfer to a large bowl and mash with a potato masher or fork until smooth—no lumps, no grit.
Mix the Creamy Sweet Potato Filling
To the mashed sweet potatoes, add the 0.5 cup evaporated milk, 0.5 cup heavy cream, 0.25 cup granulated sugar, 1 tsp vanilla extract, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 0.5 tsp salt. Stir until completely combined and smooth.
This is where the magic happens—the spices and cream create that perfect balance of sweetness and warmth. Taste as you go and adjust sugar if needed (I usually add another 1-2 tablespoons since sweet potatoes vary in natural sweetness). The mixture should be thick but spreadable.
Real talk: if it's too thick, add 1-2 tablespoons more evaporated milk to loosen it. Too thin? A quick simmer on the stove (covered) for 2-3 minutes will thicken it naturally. Transfer the filling to a greased 9x13-inch baking dish and spread it evenly.
Prepare the Pecan-Coconut Topping
In a medium bowl, combine the 2 cups pecans, 1 cup shredded coconut, 0.5 cup all-purpose flour, 1 cup brown sugar, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 0.5 tsp salt. Mix thoroughly with your hands or a fork—you want every pecan and coconut flake coated in that spiced sugar mixture.
Here's where it gets fun—add the 0.5 cup cold cubed unsalted butter and work it in with your fingers until the mixture resembles wet sand. The butter should be evenly distributed but still visible in small chunks. This creates pockets of flavor and texture when baked.
Spread the topping evenly over the sweet potato filling, pressing down gently with your fingers. Don't worry if it looks messy—this topping is meant to be rustic and crunchy. The edges should be slightly thicker than the center for extra crispiness.
Bake to Golden Perfection
Bake the casserole at 350°F for 35-40 minutes until the topping is deep golden brown and bubbly at the edges. The filling should be set but still slightly jiggly in the center—it'll continue cooking slightly after removal.
Watch closely during the last 5 minutes of baking. The topping should be crisp enough to hold its shape when you lift a corner. If it's browning too quickly, tent loosely with foil to prevent burning while allowing the filling to finish cooking.
Let the casserole rest for 10 minutes before serving. This resting time lets the filling set properly and prevents a runny center. The contrast of warm, creamy filling with crispy, nutty topping is what makes this dish truly special.
Serve Warm with Holiday Flair
Slice into 6 equal portions (this makes 6 generous servings) and serve immediately. The topping should be crunchy enough to bite into while the filling remains custardy and warm. Garnish with an extra sprinkle of shredded coconut if you're feeling fancy.
This casserole is perfect for holiday gatherings—it's hearty enough for a main dish but light enough for a side. The tropical pecan-coconut topping adds a unique twist that'll have your guests asking for seconds. Store leftovers covered in the fridge for up to 3 days, though I doubt you'll have any!
Pro Tips For Making Sweet Potato Casserole Recipe With Pecan And Coconut Topping
- ROAST THE POTATOES FIRST: I learned this the hard way—skipping the roast makes the casserole gummy. Toss peeled, cubed sweet potatoes in 1 tablespoon oil, salt, and a pinch of cinnamon, then roast at 400°F (200°C) for 25-30 minutes until tender and caramelized. This step cuts baking time later and deepens the flavor.
- TOAST THE PECANS: Crunchy pecans make or break this topping. Spread pecans on a dry baking sheet and toast at 350°F (175°C) for 5-7 minutes, stirring once, until fragrant and lightly golden. Let them cool completely before mixing—hot pecans release oils that turn the coconut soggy.
- MIX DRY INGREDIENTS LAST: Combine brown sugar, shredded coconut, and toasted pecans after the butter’s melted. Sprinkling dry ingredients into warm butter creates steam, which locks in moisture and prevents the topping from turning into a sticky mess. Work fast—this step needs to happen within 2 minutes of the butter cooling slightly.
- USE COLD COCONUT: Skip the pre-shredded coconut—it’s often packed with moisture. Instead, grate fresh unsweetened coconut yourself (or buy the flaked kind) and chill it for 30 minutes before mixing. Cold coconut stays crisp in the oven and won’t clump into a paste. (Yes, it’s extra work, but your topping will thank you.)
Regional styles of sweet potato casserole recipe with pecan and coconut topping
Southern Comfort Classic
In the American South, this casserole is a holiday staple—often called "sweet potato pie casserole" for its custard-like texture. Traditional versions use a simple crumb topping with just butter, flour, and brown sugar, but my tropical twist keeps the Southern spirit while adding a modern flair.
I grew up with my grandma's version where she'd add 1/2 cup chopped pecans to the crumb topping—this inspired my full pecan-coconut upgrade. The key Southern touch? Cooking the sweet potatoes until they're almost caramelized before mashing for deeper flavor. 🍠
Hawaiian Luau Twist
This version takes inspiration from Hawaiian sweet potato dishes like poi (fermented taro paste) by incorporating coconut in both the filling and topping. For an authentic Hawaiian touch, swap 1/4 cup of the evaporated milk for coconut milk and add 1 tsp lime zest to the filling.
The lime brightens the sweetness, just like you'd find in traditional Hawaiian sweet potato recipes. Garnish with toasted macadamia nuts instead of pecans for a true island vibe. Serve with a side of grilled pineapple for the full luau experience. 🌺
New England Maple Glaze
Up north, maple syrup becomes the star—replace the brown sugar in the topping with 1/2 cup pure maple syrup (like Grade B Vermont maple for that caramelized depth).
Add 1/4 cup chopped walnuts to the pecans for a local touch, and finish with a drizzle of maple glaze (simmer 1/4 cup maple syrup with 1 tsp cornstarch until thickened). This version feels cozy enough for a New England Thanksgiving, where maple is king.
The walnuts add a subtle earthiness that balances the coconut's sweetness. 🍁
Texas BBQ Side Dish
In Texas, sweet potato casseroles often get a smoky kick—add 1/2 tsp smoked paprika to the filling and top with 1/4 cup chopped bacon mixed into the pecan topping. For extra heat, sprinkle 1/4 tsp cayenne pepper over the filling before baking.
Serve alongside pulled pork or brisket for a Texas-style feast. The bacon adds a salty crunch that pairs perfectly with the tropical coconut. Trust me, Texans will love this unexpected fusion. 🌶️
Modern Vegan Adaptation
For plant-based cooks, swap the butter for vegan butter or coconut oil, use coconut cream instead of heavy cream, and add 1 tbsp maple syrup to the filling. The topping stays the same but becomes dairy-free—just make sure your shredded coconut is unsweetened.
For extra richness, add 2 tbsp tahini** to the filling. This version keeps all the tropical flavors while making it accessible for vegan diets. The texture remains creamy and the topping stays gloriously crunchy. 🌱

Frequently asked questions
Can I make this casserole ahead of time?
Assemble the casserole completely (including the topping) and refrigerate it overnight. Bake it straight from the fridge at 350°F for 45-50 minutes—the extra time ensures the topping gets extra crispy. Just add 5-10 minutes to the baking time if it's cold.
How do I keep the topping extra crispy?
Use cold butter cubes in the topping and bake at 350°F instead of higher heat. For maximum crunch, broil for 1-2 minutes at the very end (watch closely!). Also, spread the topping slightly thicker on the edges—they crisp first.
What if I don't have pecans?
No problem! Swap for walnuts or almonds (chopped) for a similar texture, though pecans' buttery flavor is ideal. For a nut-free option, try crushed graham crackers or toasted oats—they'll still add crunch, though without the same richness.
Can I make this gluten-free?
Yes! Replace the all-purpose flour in the topping with almond flour or gluten-free 1:1 baking flour. The texture will be slightly different but still delicious. Just make sure your shredded coconut is certified gluten-free too.
Why is my topping soggy?
Soggy topping usually means the filling wasn't fully set before adding the topping. Always bake the sweet potato layer for 20-25 minutes before adding the topping, then bake together. Also, make sure your butter is cold when mixing into the topping.
