Sweet potato casserole is a beloved Thanksgiving dish, but it’s also delicious all year round. This version takes it to a whole new level with a brown sugar pecan crumble topping. Traditionally, it’s a side dish, but this variation can easily pass as a dessert.


This yummy side dish requires only a handful of ingredients. Here is what you’ll need for both the sweet potato mix and streusel topping.

Layer 1: Sweet Potato Filling

For the sweet potato layer, you likely have almost everything you need in the fridge or pantry. The canned yams may be the one exception.

1/4 cup sugar – granulated white sugar.

1/2 cup milk – we use 2% milk.

1/2 cup butter – melted butter or margarine will work.

2 eggs – whole eggs, both whites and egg yolks.

1 tsp vanilla – pure vanilla extract.
