Ingredients & Substitutions

These are the main ingredients and substitutions for gluten free sweet potato casserole. Scroll down to the recipe card for full ingredients list and instructions.

Mashed sweet potatoes make up the bulk of the filling. Roast or boil sweet potatoes until tender. About 2 large sweet potatoes or 3 to 4 medium sized are sufficient.

Canned coconut milks adds creaminess. If desired, use half and half or creamer. Other dairy free milks may be too thin.

One egg helps bind the filling together.

Light brown sugar contributes sweetness to both layers. If desired, use coconut sugar or maple sugar.

In the filling, pumpkin pie spice adds a great flavor. If needed, replace with cinnamon and a pinch of nutmeg.

Both layers require butter. For the filling, use melted butter. For the topping, use cold butter. Then, use your hands to incorporate butter into the crumble topping.

Vanilla extract adds a warmth to both layers.

Add in a pinch of sea salt to the filling if desired.

For the topping, chopped pecans add crunch.

Lastly, gluten free 1 to 1 flour helps thicken the crumble topping. I do not recommend an alternative flour in this specific recipe. Check out this Paleo Sweet Potato Casserole for grain free.
