A quick and easy sweet potato casserole with a crunchy pecan streusel topping, perfect for busy weeknights or holiday dinners. This happy accident turned recipe is made with simple ingredients and comes together in under 30 minutes.
Slice sweet potatoes evenly for even cooking. Cold butter is essential for a crumbly streusel. Watch the oven at the end to prevent burning. For make-ahead, assemble without baking, cover, and refrigerate up to 24 hours; add 10 minutes to baking time. Leftovers keep in the refrigerator for up to 4 days or freeze for up to 3 months.
