Description
A classic Southern holiday side dish featuring roasted sweet potatoes combined with warm spices, maple syrup, brown sugar, raisins, and marshmallows, topped with maple-glazed pecans for the perfect sweet and crunchy finish.
Ingredients
Roasted Sweet Potatoes:
- 4 large sweet potatoes, peeled and cubed
- 2–3 tablespoons extra virgin olive oil
- 1 teaspoon ground cinnamon
- ½ teaspoon ground nutmeg
Filling / Casserole Base:
- ½ cup almond milk (or whole milk / plant-based milk)
- 2 teaspoons vanilla extract
- 4 tablespoons unsalted butter, cut into small cubes
- ⅓ cup brown sugar
- ¼ cup pure maple syrup
- 1 teaspoon ground cinnamon
- ⅛ teaspoon ground nutmeg
- Pinch of ground allspice
- 1 cup raisins (soaked and drained)
- 2 cups marshmallows
Topping:
- 1½ cups raw pecans
- ¼ cup pure maple syrup
Instructions
Preheat your oven to 400°F (about 200°C). Line a large baking sheet with parchment paper—this makes cleanup SO much easier, trust me!
Peel your sweet potatoes and cut them into roughly 1-inch cubes. Try to keep them fairly uniform so they roast evenly. In a large bowl, toss the cubed sweet potatoes with 2–3 tablespoons of olive oil, 1 teaspoon cinnamon, and ½ teaspoon nutmeg until every piece is well coated.
Spread the seasoned sweet potatoes on your prepared baking sheet in a single layer. Don’t overcrowd them—they need space to caramelize properly! Roast for 50–60 minutes, stirring once or twice during cooking. You want them tender, golden, and with some beautiful caramelized edges. Remove from the oven and let them cool slightly while you prepare the rest.
Turn your oven down to 375°F (about 190°C). Grease your 9×13 inch baking dish with butter or cooking spray.
This is where the magic happens! In a large bowl, combine your roasted sweet potatoes, milk, vanilla extract, brown sugar, maple syrup, cinnamon, nutmeg, allspice, drained raisins, and marshmallows. Stir gently—you want some of the sweet potatoes to mash and create a creamy base while leaving some chunks for texture. It’s perfectly imperfect!
Spread the sweet potato mixture evenly into your prepared baking dish. Now nestle those butter cubes throughout the filling—they’ll melt and create pockets of richness. Feel free to tuck in a few extra marshmallows on top if you’re feeling generous (and I always am!).
In a medium bowl, toss the pecans with ¼ cup maple syrup until they’re nicely coated. This maple coating will help them toast beautifully and add an extra layer of flavor.
Sprinkle the maple-coated pecans evenly over the sweet potato mixture. Cover the dish loosely with aluminum foil and bake for about 15 minutes.
Remove the foil and continue baking for an additional 15 minutes, or until the topping is golden brown, the marshmallows are puffed and starting to turn golden, and the pecans are beautifully toasted. Your kitchen will smell AMAZING!
Remove from the oven and let the casserole cool for about 5–10 minutes before serving. This allows everything to set up slightly and makes it easier to serve.
Notes
- Even Roasting: Cut your sweet potatoes as uniformly as possible. I aim for 1-inch cubes. This ensures they all finish cooking at the same time.
- Check for Doneness: Your roasted sweet potatoes should be fork-tender and have some caramelized edges. If they’re not quite there at 50 minutes, give them another 5–10 minutes.
- Prevent Burning: Watch your pecan topping during that final uncovered bake. If they’re browning too quickly, you can tent the dish loosely with foil again.
- Marshmallow Magic: Don’t stir the marshmallows in too vigorously—you want them to maintain their shape somewhat so they create those lovely melty pockets throughout.
- Make It Gooey: Want extra marshmallow goodness? Add more marshmallows on top before that final bake. They’ll get golden and toasted on top while staying gooey underneath.
- Common Mistake to Avoid: Don’t overwork the mixture when combining everything. You’re not making mashed potatoes—you want textural variety!
