Best Gluten Free Sweet Potato Casserole

This simple gluten-free sweet potato casserole is absolutely amazing for a Thanksgiving side dish! Cinnamon meets toasty pecans to make a delectable streusel topping over smooth and creamy sweet potatoes. It's sure to become a family favorite.

This sweet potato casserole recipe is a holiday favorite, ideal for any festive occasion, not just Thanksgiving. What's great is that all the ingredients are readily available at your local grocery store. A delightful treat that brings the warmth of the holiday season to any meal!

Rest assured, these potatoes don't come with the traditional, but often disappointing, marshmallow topping you might expect. Instead, they have a mouthwatering streusel pecan crumble that will truly impress!

I love making this traditional sweet potato casserole, and gluten-free green bean casserole every Thanksgiving no matter what. They're crowd-pleasing recipes that everyone looks forward to. Served up with a tasty gluten-free turkey, gluten-free stuffing with apples and sausage, and gluten-free crescent rolls, they create one delicious and well-rounded meal.

Why you'll love this recipe

• Despite its simplicity, this casserole is bursting with the rich flavors of sweet potatoes, nutmeg, and cinnamon. Just like our gluten free pumpkin bars.
• Tailored for those following a gluten-free diet, it allows everyone to enjoy a classic holiday dish without worry.
• With the Instant Pot method, you can have perfectly cooked sweet potatoes in a fraction of the time.
• If there are any leftovers (though it's doubtful!), they taste just as delicious the next day, making it a practical dish for busy times.

Sweet Potato Pecan Streusel Topping

I've never been a big marshmallow fan so topping a vegetable with them has never hooked me. This pecan, brown sugar streusel topping though... Now that's a different story!

This topping is made simply with brown sugar, chopped pecans, gluten-free flour and butter. It really takes sweet potato casserole to the next level and I bet your kids will even ask for seconds (mine always do). 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.
• Eggs
• 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.

Instant Pot Sweet Potatoes

Making large sweet potatoes in the instant pot is truly the best way to do it. It takes a fraction of the time baking does and is so easy for making creamy sweet potatoes. Rachel from Rachel Cooks has a great instant pot sweet potatoes recipe I highly recommend following.

It will make this recipe even easier than it already is. Plus, clean up is a breeze! Learn how to cook sweet potatoes here too. They are great for making mashed sweet potatoes too! Serve them up with air fryer BBQ chicken for a delicious meal.

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.

Storage

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 degrees 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 thaw. Once thawed, bake as directed and make the streusel while it is baking.
