This Easy Sweet Potato Casserole with Pecan Streusel is a quick and delicious weeknight side dish that comes together in about 45 minutes. Boiled sweet potatoes create a silky, creamy base topped with a crunchy, buttery pecan streusel.
Boil sweet potatoes whole for the best texture. Toast pecans lightly before using for extra flavor. Keep streusel butter cold for crumbly topping. Do not overmix sweet potatoes. Can be assembled a day ahead (without streusel) and refrigerated; add streusel before baking and add 10-15 minutes if baking from cold.
