This easy yam casserole with marshmallows combines canned yams, pineapple, and brown sugar for a classic holiday side dish that’s sweet, buttery, and perfectly golden on top.
Preheat the oven to 350°F and lightly grease a 1½-quart casserole dish.
Mash the drained yams in a large bowl. Drain the pineapple, reserving the juice. Add the pineapple juice to the mashed yams, then mix in the brown sugar and melted butter until well combined. Stir in the crushed pineapple and chopped pecans.
Spoon the mixture into the prepared casserole dish and bake for 20 minutes.
Remove from the oven, sprinkle the marshmallows evenly over the top, and return to the oven. Bake for about 10 more minutes, or until the marshmallows are golden brown.
