This sweet potato casserole features a creamy, roasted sweet potato filling topped with a crunchy pecan streusel. It’s a crowd-pleasing holiday side dish that can be made ahead and is perfect for Thanksgiving or any gathering.
Roast sweet potatoes instead of boiling to avoid a watery filling. Use melted butter in the streusel for a stable crumble that doesn’t sink. Assemble without streusel up to 24 hours ahead; add streusel just before baking. For a nut-free version, replace pecans with rolled oats.
