A stress-free, crowd-pleasing side dish that balances creamy, spiced sweet potatoes with a crunchy pecan crumble topping. Perfect for holidays or busy weeknights, this recipe can be assembled ahead of time for effortless elegance.
For best results, let sweet potatoes cool before mashing to avoid a gummy texture. Toast pecans in a dry pan for 2-3 minutes before chopping for enhanced flavor. If making ahead, let the casserole sit at room temperature for 30 minutes before baking and add 5-10 minutes to the baking time if starting from cold. Do not freeze marshmallows as they become rubbery.
