Ingredients

For the Roasted Sweet Potatoes:

• 4 large sweet potatoes, peeled and cut into medium cubes
• 2–3 tablespoons extra-virgin olive oil (or coconut oil)
• 1 teaspoon ground cinnamon
• ½ teaspoon ground nutmeg

For the Filling:

• ½ cup milk (almond milk works too)
• 2 teaspoons vanilla extract
• 4 tablespoons unsalted butter, 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

For the Topping:

• 1 ½ cups raw pecans (whole or roughly chopped)
• ¼ cup pure maple syrup

Instructions

1. Roast the Sweet Potatoes
   • Preheat your oven to 400°F (about 200°C).
   • Toss the sweet potato cubes with olive oil, cinnamon, and nutmeg until well coated.
   • Spread them in a single layer on a baking sheet lined with parchment paper.
   • Roast for 50–60 minutes, or until the potatoes are tender, slightly charred, and golden. Once done, remove and let them cool a little.
2. Prepare the Filling
   • While the potatoes roast (or once they’ve cooled a bit), combine the roasted potatoes in a large bowl with milk, vanilla extract, butter, brown sugar, maple syrup, cinnamon, nutmeg, allspice, and raisins.
   • Mix gently — you want a mix of mashed and chunkier potato pieces so it’s creamy but has texture.
   • Fold in 2 cups of marshmallows, distributing them evenly but not mashing them completely.
3. Assemble the Casserole
   • Preheat your oven to 375°F (around 190°C).
   • Lightly grease a 9×13-inch baking dish.
   • Spread the sweet potato filling evenly in the dish. Dot the top with any remaining butter pieces, gently tucking them in.
   • In a separate bowl, mix the pecans with ¼ cup maple syrup until they’re evenly coated. Then sprinkle this maple-pecan mixture generously over the sweet potato layer.
4. Bake
   • Cover the dish loosely with aluminum foil and bake for 15 minutes.
   • Remove the foil and bake for another 15 minutes (or until pecans are slightly crisp and everything is bubbling).
5. Cool & Serve
   • Take the casserole out of the oven and let it cool slightly — about 10 minutes — so the filling sets a bit.
   • Serve warm in generous scoops, letting the top crackle under the spoon as you eat.

You Must Know (Helpful Tips)

• Roasting vs. boiling: Roasting sweet potatoes concentrates their flavor and reduces excess moisture — that’s why this recipe roasts them.
• Soak the raisins: If your raisins are dry, soak them in hot water for a few minutes, then drain — this makes them plump and juicy in the casserole.
• Add marshmallows last: Folding them in gently rather than mashing ensures little pockets of sweetness melt beautifully.
• Even pecan coverage: Make sure the pecans are well coated in syrup so they crisp nicely when baked.
• Let it rest: Allowing the casserole to rest after baking helps prevent it from being too runny.

Storage Tips

• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Reheating: Warm in a 350°F oven for 10–12 minutes, or microwave individual portions with a little sprinkle of milk to revive creaminess.
• Make-ahead: You can roast the sweet potatoes a day ahead, mash and mix the filling, and then assemble just before baking.

Ingredient Substitutions

• Milk: You can use whole milk, oat milk, or any plant-based milk.
• Butter: For a vegan option, substitute with vegan butter or coconut oil.
• Marshmallows: Use vegan marshmallows to keep it plant-based.
• Pecans: Swap in walnuts or hazelnuts if preferred.
• Raisins: Use dried cranberries, chopped dried apricot, or omit if desired.

Serving Suggestions

• Serve as a side dish alongside roasted turkey, ham, or glazed ham for the holidays.
• Enjoy it as a sweet treat or dessert — it’s rich enough to feel like dessert.
• Pair with a fresh green salad to balance sweetness, or roasted Brussels sprouts for more texture contrast.
• Garnish with a sprinkle of sea salt or a drizzle of extra maple syrup just before serving.

Pro Tips

• For extra flavor depth, add a splash of bourbon or rum to the filling along with the raisins.
• Toast the pecans lightly in a dry skillet for 2–3 minutes before mixing with syrup to bring out their nuttiness.
• Broil the top for 1–2 minutes at the end of baking if you want the pecans to caramelize more (watch carefully to prevent burning).
• Use a shallow baking dish so the casserole bakes more evenly and crisps up nicely on top.

Frequently Asked Questions (FAQ)

Can I make this casserole nut-free?
Yes — simply skip the pecans, or substitute with sunflower seeds or pumpkin seeds for crunch.

What if I don’t have marshmallows?
You can omit them entirely, or top with a brown sugar crumble for a different texture.

Does this work as a vegan recipe?
Absolutely. Use plant-based milk, vegan butter, and vegan marshmallows, and you’re good to go.

How do I prevent the casserole from being too sweet?
Taste as you go: you can reduce the maple syrup or brown sugar a little if you prefer a milder sweetness.

Is it safe to make this ahead for a holiday dinner?
Yes — roast the sweet potatoes in advance, mash and mix the filling, and then assemble the day of. Reheat gently before serving.
