While it isn’t a healthy sweet potato casserole it is delicious and worth it!
What you’ll need
- Sweet potatoes – Roughly 4 large sweet potatoes are perfect for this recipe.
- Brown sugar – You’ll need brown sugar for the casserole and the pecan topping. Feel free to replace with coconut sugar but I would not recommend replacing with maple syrup.
- Milk – Regular milk works best but feel free to swap for a mild plant based milk.
- Butter – You’ll need melted butter for the casserole and cold butter for the streusel topping.
- Vanilla extract – Make sure you have gluten free vanilla extract.
- Spices – Nutmeg, cinnamon, and a dash of salt is all you need to take this recipe to the next level.
- Pecans – Pecan halves or pieces will work
- Flour – I like to use a good brand of gluten-free all-purpose flour like Bob’s red mill but you can also make your own gluten free flour.

Can I make this casserole vegan?
You can absolutely make this a vegan sweet potato casserole. Swap the butter for dairy-free butter or coconut oil, milk for a type of dairy free milk, and eggs for flax eggs or another egg replacer.
Full fat coconut milk, almond milk, or another creamy dairy-free milk are great options. For thinner milks like almond, you may need less. Making this casserole vegan allows those with all different types of allergy restrictions to enjoy on Thanksgiving day.
Storing – Keep this gluten-free sweet potato casserole in the fridge for 3-5 days in an airtight container or a the cooled baking dish covered with plastic wrap. Just reheating as needed in the microwave or bake at 250 until warmed through. It is a delicious leftover dish!
Freezing – For freezing, I recommend following all the instructions up until the baking and streusel making. Prepare the batter and freeze in freezer safe container. When you are ready to bake, remove from the freezer and unthaw. Once thawed, bake as directed and make the streusel while it is baking.
