Best Gluten Free Sweet Potato Casserole
Sweet potato casserole, along with green bean casserole, gravy, and traditional GF stuffing are staple side dishes at the Thanksgiving table. When accommodating guests for a gluten-free Thanksgiving dinner, though, it’s important to provide allergy-friendly foods all will love!
This easy gluten-free sweet potato casserole uses Chex cereal, pecans, butter, and brown sugar for a crunchy, sweet gluten-free topping. The ingredients are safe for all to enjoy, widely available, and affordable, just like the recipes highlighted in my gluten-free cookbook.
To make a dairy-free gluten-free sweet potato casserole, simply swap out the cream with coconut milk and the butter with dairy-free butter. Additionally, it can be made without eggs for an egg-free or vegan casserole.

Ingredient Tid Bits
Many of the ingredients for gluten-free sweet potato casserole may be easily modified for dairy-free or vegan diets.
- Sweet Potatoes – Roasting the sweet potatoes concentrates and caramelizes the flavor, eliminating the likelihood of a runny or watery casserole, which often happens with boiled potatoes.
- Heavy Cream – A small amount adds an extra creaminess to the mashed sweet potatoes. Substitutions include half and half, whole milk, softened cream cheese, or a non-dairy milks, such as coconut or almond milk for a dairy-free casserole.
- Butter – For a dairy-free recipe, replace with plant-based vegan butter or coconut oil.
- Brown Sugar or Maple Syrup – Adjust the amount to taste, but generally I find sweet potato casserole recipes to be overly sweetened. A reduced amount is included in the recipe card.
- Egg – Used as a binder for the potatoes, but for an egg-free sweet potato casserole substitute an egg replacer or 1 tablespoon cornstarch.
- Orange Zest – Not an overpowering flavor, but adds an unique hint of citrus that compliments the potatoes. It may be omitted or replace with ½ teaspoon cinnamon, vanilla extract, or a dash of nutmeg.
- Chex Cereal – This is a spin on southern casseroles with a crunchy cornflake topping, which unfortunately are not gluten-free. Use rice or corn Chex, or gluten-free cornflakes, such as Nature’s Path.
- Pecans – Chopped pecans adds a salty crunch to compliment the topping’s sweetness. If you prefer a different gluten-free topping, such as marshmallows, see the gluten-free sweet potato topping section below.

(Below shows step-by-step photos and modified instructions. For the complete recipe, along with ingredient amounts, scroll down to the recipe card.)



- Preheat the oven to 400ºF and line a baking pan with foil or parchment paper. Prick the sweet potatoes 5-6 times with a fork. Roast for 50-60 minutes, turning halfway, until fork tender.
- Once the potatoes are cool enough to handle, peel away the skins and transfer the flesh to a large mixing bowl. Use a hand held mixer to mash the potatoes until smooth.
- Pour in the heavy cream, softened butter, brown sugar, egg, orange zest, and salt. Beat again until well combined. Spread in a 2-quart baking dish.
- For the topping, combined the crushed cereal, pecans, melted butter, brown sugar, cinnamon, and pinch of salt. Sprinkle on top of the sweet potato mixture.
- Bake in a 350ºF oven for 30 minutes, or until the potatoes are heated through and the top is golden.
More GF Sweet Potato Casserole Toppings
Instead of a pecan topping, you may also make gluten free sweet potato casserole with marshmallows. You will need a 10-ounce bag of mini marshmallows, but do not sprinkle on top until the last 5 minutes of baking.
You may also do a half and half topping with pecan crumble on one side (half recipe) and marshmallow topping on the other. This gives options for guest to choose what they prefer!

Replace the butter with plant-based butter or coconut oil. For the heavy cream, use full-fat coconut milk or dairy-free almond milk. For an egg-free casserole, substitute 1 tablespoon cornstarch or use an egg replacer, such as Neat Egg.Marshmallow Topping
A marshmallow topping may be substituted for the cereal topping. You will need a 10-ounce bag of mini marshmallows, but do not sprinkle on top until the last 5 minutes of baking. You may also do a half and half topping with pecan crunch on one side (using a half recipe) and marshmallow topping on the other.
