A quick and easy weeknight sweet potato casserole with a buttery, crunchy pecan streusel topping. This comforting dish lets the natural sweetness of sweet potatoes shine, with brown sugar and pecans playing a supporting role.
Toast pecans first for maximum crunch. Use cold butter for the streusel to keep it crumbly. Let the casserole rest for 5 minutes after baking to set. For make-ahead: assemble without baking, cover, and refrigerate up to 24 hours; add 10-15 minutes to baking time. For freezing: assemble unbaked, wrap tightly, freeze up to 3 months; thaw overnight in fridge before baking.
