The warm glow of oven-baked sweet potatoes fills the kitchen with nutty toasted scents and glistening buttery steam as I tuck crunchy pecan streusel into a silky mash. After four rounds of tweaking, this Pecan Sweet Potato Casserole hits that sweet spot between tender sweet potatoes and crackling brown sugar topping. My discovery: adding a pinch of freshly grated nutmeg makes every bite sing.

- A North American holiday classic with roots in Southern kitchens.

A Little Background
On my first test run last November, I poked the potatoes too few times and ended up with steam pockets instead of golden skins. Since then, I stick to even pricks and a full 55 minutes at 350°F. Watching my kids press for extra maple drizzle became their favorite Sunday ritual.
Key Ingredients for Pecan Sweet Potato Casserole
- Sweet potatoes (2 pounds): starchy foundation for that silky mash; choose medium-sized for even cooking.
- Full-fat coconut milk (1/4 cup): adds richness; swap with heavy cream if preferred.
- Pure maple syrup (2 tablespoons): natural sweetener; boost sweetness or swap with honey.
- Chopped pecans (3/4 cup): for crunch; a quick toast deepens their flavor.
- Light brown sugar (3/4 cup): packed sweetness that caramelizes in the oven.
- Cold unsalted butter (4 tablespoons): cubed to bind the streusel; keep it chilled.
How to Make Pecan Sweet Potato Casserole
- Preheat the oven to 350°F and generously prick each sweet potato all over with a fork.
- Arrange potatoes directly on the center rack and bake until a skewer slides through easily, about 45 to 55 minutes.
- Reduce the oven heat to 325°F. Slice each potato lengthwise and scoop the soft flesh into a bowl. Add 1/4 cup full-fat coconut milk, 2 tablespoons pure maple syrup, 1/4 teaspoon salt, 1/4 teaspoon ground cinnamon and a pinch of freshly grated nutmeg. Mash until mostly smooth.
- Transfer the mash to an 8×8-inch baking dish, smoothing the top with a spatula.
- In a separate bowl, stir together 3/4 cup chopped pecans, 3/4 cup all-purpose flour, 3/4 cup light brown sugar and 1/4 teaspoon salt. Scatter 4 tablespoons of cubed cold butter over the mixture, then use a pastry cutter (or two knives) to work until coarse clumps form.
- Evenly sprinkle the streusel atop the sweet potato layer.
- Bake until you hear soft crackling and the topping is golden brown, about 25 to 35 minutes. I aim for 25 minutes and then check every five.
- Remove from the oven and rest for 5 minutes. Drizzle any remaining maple syrup over each portion before serving.

Pro Tips & Troubleshooting
- Testing note: I noticed during my third bake the streusel browned too quickly—tent the dish with foil for the last 10 minutes if needed.
- If your topping feels soggy, let it cool in the oven with the door cracked open for a few minutes to crisp up.
- Stir in a pinch of cayenne or smoked paprika to the mash for a subtle warmth.
- Halve or double easily by swapping to a 9×9 or 13×9-inch pan; adjust baking time by ±5 minutes.
Storage & Make-Ahead Guide
You can assemble the mash and streusel separately up to a day ahead—store covered in the fridge. Once baked, keep leftovers in an airtight container at 40°F or below for up to 4 days, or freeze portions for up to 2 months. To reheat, warm at 325°F until heated through. Testing note: after freezing, I found the texture stays silky if thawed overnight in the fridge before baking.
Serving Suggestions
Serve warm alongside roast turkey or glazed ham, or top with a dollop of vanilla Greek yogurt and a sprinkle of fresh chives for a sweet-savory twist.
