It just isn’t the holidays without Sweet Potato Casserole. Thanksgiving is the one day of the year we can pass a dessert off as a side dish.

And, although they’re topped with a deliciously sweet crumb topping, sweet potatoes are packed with beta-carotene and other antioxidants. So I will argue that this is a healthy side dish. This gluten-free sweet potato casserole with pecan topping is bound to become a new holiday favorite.

Sweet potato casserole is my favorite Thanksgiving side. You can better believe if it’s not on the menu then I’m bringing it. It’s actually quite simple to make gluten-free. You just use gluten-free all purpose flour in place of regular flour. All of the other ingredients – sweet potatoes, sugar, butter, eggs, and pecans are naturally gluten-free. This recipe also has a dairy-free option too!

Why You Need This Recipe

  • It’s perfect for the holidays, but if you want to make it on a sunny summer or spring day, I’m not judging! It’s just that delicious.
  • It’s great for meal prepping or holiday prepping. You can prep the dish ahead of time and then just assemble and bake. Make the crumb topping and the sweet potato mixture separate and refrigerate until time to bake.
  • It’s easy to make dairy-free or even paleo.

Key Ingredients

Sweet potatoes – You will need 6 cooked sweet potatoes with the skins removed. It’s important to cook the sweet potatoes properly. If you overcook the sweet potatoes they can get watery and if they’re undercooked they lose their creaminess. Cook them until they a fork easily slides into the flesh.

Coconut sugar – I prefer coconut sugar but you can use brown sugar if that’s what you have on hand. For a paleo gluten-free sweet potato casserole, be sure to use coconut sugar as it’s considered less refined.

Butter or ghee – Important for both the filling and the topping, butter is what makes the sweet potato mixture super creamy. For a paleo version be sure to use grass-fed butter. If you are dairy-free you can use vegan or dairy-free butter in its place.

Gluten-free flour – I prefer Bob’s Red Mill 1:1 All Purpose Flour but you can use your favorite gluten free flour brand. For a paleo version, use almond flour.

Eggs help make the casserole a little bit fluffy. They are a nice touch, but you can leave them out for vegan or egg-free diets.

Pecans – Pecans add such great flavor and crunch but if you dislike pecans you can leave them out or sub in walnuts.

Recipe Tips & Substitutions

  • To cook the sweet potatoes, wash and pat them dry. Poke holes with a fork all around each potato and bake at 400°F for 45-60 minutes. Remove them from the oven and let them cool slightly. Then, carefully remove the skins and place the cooked sweet potato flesh in a large bowl. Alternatively, you can make Instant Pot Sweet Potatoes which saves a lot of time.
  • If you aren’t on a gluten-free diet, you can use regular all-purpose flour instead of a gluten-free flour.
  • You can use a 9×13 casserole dish or a square one as well.
  • If you don’t like pecans, you can substitute them for chopped almonds or walnuts.
  • Store any leftovers in a covered container in the refrigerator for up to 4 days. Reheat before serving.
