Low Sugar Sweet Potato Casserole with Pecan Streusel

Silky mashed sweet potatoes get whipped with butter, milk, eggs, vanilla, and a warm hit of cinnamon and nutmeg until the filling turns glossy and completely smooth. That base gets spread into a baking dish and blanketed with a thick layer of roughly chopped pecans worked into a buttery, clumpy streusel that turns deeply golden as it bakes. The result is a casserole with two distinct textures in every scoop: soft, custardy sweet potato underneath and a crunchy, nutty topping on top. It bakes up puffed at the edges and set in the center, then rests just long enough to slice into clean, holiday-worthy squares. This is an easy make-ahead side that fits neatly into an Added Sugar–friendly spread without sacrificing that classic streusel crunch.
