Instructions
Roast the Sweet Potatoes
- Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper.
- Toss cubed sweet potatoes with olive oil, cinnamon, and nutmeg.
- Spread on the baking sheet in a single layer and roast for 50–60 minutes until tender and golden. Let cool slightly.
Prepare the Casserole Filling
- Preheat oven to 375°F (190°C) and grease a 9×13-inch baking dish.
- In a large bowl, combine roasted sweet potatoes, almond milk, vanilla, butter, brown sugar, maple syrup, cinnamon, nutmeg, allspice, raisins, and marshmallows. Mix until well combined, leaving some chunks for texture.
- Scoop the mixture into the prepared baking dish. Tuck in extra marshmallows and butter pieces for gooeyness.
Make the Topping
- In a small bowl, combine pecans and maple syrup.
- Spread topping evenly over the casserole. Cover with foil and bake 15 minutes.
- Remove foil and bake another 15 minutes until the top is golden and marshmallows are melted.
- Let cool slightly before serving.
Tips & Tricks
- Make Ahead: Roast sweet potatoes in advance and store in an airtight container in the fridge. Assemble and bake on the day of serving.
