Ingredients

  • Vanilla extract: brings a subtle warmth and enhances the sweet potatoes
  • Ground cinnamon: infuses each bite with that familiar holiday aroma

My favorite part is always the topping especially when the chopped pecans toast up during baking and I remember how my grandmother used to tuck in extra pecans just for me when I was little

Storage Tips

Refrigerate leftovers in a tightly sealed container for up to four days and reheat portions in the oven or microwave for best results. You can also cover and freeze unbaked or baked casserole for up to two months. Thaw overnight in the refrigerator before reheating

Ingredient Substitutions

Omit pecans for a nut-free version and substitute rolled oats or sunflower seeds in the streusel. For a lighter casserole use half unsweetened applesauce in place of butter or swap whole milk for a non-dairy option like oat milk. Try adding a touch of fresh orange zest or a pinch of nutmeg to the sweet potato base for a festive spin

To freeze for later assemble the casserole up through the streusel step but do not bake then wrap tightly with foil and freeze for up to two months. Bake directly from frozen adding fifteen extra minutes to the bake time or until hot and golden
