# How-To Steps:
01 - Preheat the oven to 350°F. Grease a 2-quart baking dish.
02 - Place sweet potatoes in a large pot and cover with water. Bring to a boil and simmer for 15 to 20 minutes until tender. Drain thoroughly.
03 - Transfer sweet potatoes to a large bowl. Add milk, butter, brown sugar, eggs, vanilla extract, cinnamon, nutmeg, and salt. Mash until smooth and fully combined.
04 - Spread the mashed sweet potato mixture evenly in the prepared baking dish.
05 - Sprinkle chopped pecans evenly over the sweet potato layer, if using.
06 - Bake uncovered for 25 minutes.
07 - Remove from oven. Evenly distribute mini marshmallows over the top. Return to oven and bake for 10 to 15 minutes until marshmallows are golden and toasted.
08 - Allow to rest for 5 minutes before serving.
# Expert Tips:
01 -
- It strikes that perfect balance between comforting and elegant, so no one questions why you're serving it.
- Once the potatoes are cooked, it comes together in minutes and practically cooks itself.
- Marshmallows do the heavy lifting—they transform something humble into something people actually get excited about.
02 -
- Drain those boiled potatoes thoroughly or you'll end up with a watery, separated casserole instead of the creamy dream you're after.
- Add the marshmallows only after the first 25 minutes of baking—early and they'll deflate into nothing.
- Don't skip the rest time; five minutes lets everything set so you can serve it with pride instead of watching it collapse on the plate.
03 -
- If your marshmallows are browning too fast before the casserole finishes cooking, tent the dish loosely with foil for the first few minutes of the marshmallow bake.
- Let your butter actually soften at room temperature instead of microwaving it—it incorporates more smoothly and makes the texture noticeably better.
