Ingredients Notes

The magic of this Gluten Free Sweet Potato Casserole lies in the thoughtful use of simple ingredients. Each one brings something unique to the dish, from texture to flavor.

Sweet Potatoes form the base of the casserole, providing natural sweetness and a creamy texture. Be sure to use fresh, firm sweet potatoes for the best results. Roasting them brings out their natural sugars, adding even more depth to the dish.

Brown Sugar sweetens the mashed sweet potatoes and adds a hint of molasses flavor. If you prefer a less sweet casserole, you can reduce the amount slightly or use coconut sugar as a substitute for a more caramel-like taste.

Butter makes the sweet potato mixture velvety smooth. For a dairy-free option, you can use coconut oil or a vegan butter alternative. The rich, buttery flavor adds a luxurious element to the dish.

Milk (or a non-dairy alternative) helps achieve the perfect consistency. I recommend using full-fat coconut milk for a hint of tropical flavor or unsweetened almond milk if you want something more neutral.

Pecan Crumble Topping is the star of this casserole. Made from chopped pecans, brown sugar, gluten-free flour, and melted butter, it creates a crispy, caramelized crust. For a nut-free version, you can use crushed gluten-free cornflakes or rolled oats mixed with a bit of brown sugar and oil.

You won't need any special equipment, just a reliable potato masher or electric mixer to ensure your sweet potatoes are silky smooth. A 9x13 baking dish works perfectly for even cooking.

How To Make This Gluten Free Sweet Potato Casserole

Making this delectable casserole is easier than you might think. Let me walk you through each step for flawless results.

Step 1: Prepare the Sweet Potatoes. Preheat your oven to 400°F (200°C). Pierce your sweet potatoes several times with a fork and place them on a baking sheet. Roast for about 45-60 minutes, or until they're fork-tender and the skins are slightly wrinkled. Once they’re cool enough to handle, peel and mash them in a large mixing bowl until smooth.

Step 2: Mix the Sweet Potato Base. Reduce the oven temperature to 350°F (175°C). Add melted butter, brown sugar, milk, eggs (or flax eggs for a vegan option), vanilla extract, cinnamon, nutmeg, and a pinch of salt to the mashed sweet potatoes. Use a potato masher or an electric mixer to blend everything together until creamy and well combined.

Step 3: Make the Pecan Crumble Topping. In a separate bowl, combine chopped pecans, gluten-free flour (such as almond flour or a 1:1 gluten-free baking mix), brown sugar, and melted butter. Stir until the mixture resembles coarse crumbs. This topping will turn golden and crunchy as it bakes, adding a delicious contrast to the creamy base.

Step 4: Assemble and Bake. Spread the sweet potato mixture evenly into a greased 9x13 baking dish. Sprinkle the pecan crumble over the top, covering the surface evenly. Bake for 30-35 minutes, or until the topping is golden brown and the casserole is heated through. Let it cool for a few minutes before serving, so the flavors can meld together beautifully.

This dish takes about 1 hour and 30 minutes from start to finish, including roasting time. It’s worth every minute!

Storage Options

Storing your Gluten Free Sweet Potato Casserole is a breeze. If you have leftovers, simply cover the dish tightly with aluminum foil or transfer portions to an airtight container. It’ll stay fresh in the refrigerator for up to 4 days.

For longer storage, you can freeze the casserole. Make sure to wrap it well in plastic wrap, followed by foil, to prevent freezer burn. It’ll keep in the freezer for up to 3 months. When you’re ready to enjoy it, let it thaw in the fridge overnight and reheat in the oven at 350°F until warmed through.

When reheating, add a small splash of milk or water to the sweet potato layer to keep it moist, especially if reheating after freezing. The topping will crisp up beautifully if you warm it uncovered for the last few minutes.

Variations and Substitutions

This recipe is wonderfully flexible, allowing you to customize it to your dietary preferences and taste.

For a vegan version, swap the butter for a plant-based alternative and use flax eggs instead of regular eggs (combine 1 tablespoon of flaxseed meal with 3 tablespoons of water per egg). Non-dairy milk, like oat or almond milk, works great in place of regular milk.

If you prefer a nut-free topping, substitute the pecans with a crunchy mixture of rolled oats and crushed gluten-free cereal. Drizzle with a bit of melted coconut oil and brown sugar for that perfect caramelized crunch.

For added texture, try folding in some toasted coconut flakes or dried cranberries into the sweet potato mixture. It adds a fun, unexpected twist that pairs beautifully with the classic flavors.

Want to make it extra indulgent? Top with marshmallows for a sweet, gooey finish. Place them on top for the last 10 minutes of baking, or until they’re golden brown.

Experiment with this Gluten Free Sweet Potato Casserole, and don’t be afraid to make it your own. Whether you stick to the classic version or put your twist on it, this dish is bound to become a staple at your holiday table!
