This sweet potato casserole features a silky, lightly spiced filling topped with a buttery, crunchy pecan-oat crumble. It’s perfectly balanced—sweet enough for a treat, savory enough to sit alongside turkey or ham—and a guaranteed crowd-pleaser for holidays and gatherings.
For a dairy-free version, use vegan butter or coconut oil and full-fat coconut milk. For gluten-free, use a 1:1 gluten-free baking flour blend and certified gluten-free oats. The casserole can be assembled up to 2 days in advance (store filling and crumble separately in the fridge). To freeze, assemble unbaked, cover tightly, and freeze for up to 3 months; bake from frozen, adding 15-20 minutes. Leftovers keep in the fridge for up to 4 days.
