Step‑by‑Step Instructions for Gluten-Free Sweet Potato Casserole
Step 1: Prepare the Sweet Potatoes
Start by scrubbing the sweet potatoes thoroughly. If you’re using an Instant Pot, place the potatoes on a trivet, add 1 cup of water, secure the lid, and set it to high pressure for 15 minutes. Allow a natural release for 10 minutes before cooling. For the oven method, preheat to 425°F, poke holes in the scrubbed potatoes, and bake for 45–50 minutes until tender. Let them cool.
Step 2: Make the Filling
Once the sweet potatoes are cool enough to handle, peel them and transfer to a large mixing bowl. Using a hand mixer, mash the sweet potatoes until smooth and creamy. Gradually mix in dairy-free butter, brown sugar, cinnamon, gluten-free flour, vanilla extract, and any desired additional sweeteners. Ensure everything is well combined and has a silky texture.
Step 3: Prepare Topping
In a separate bowl, combine chopped pecans with a drizzle of dairy-free butter and a sprinkle of brown sugar and cinnamon. Mix thoroughly until the pecans are evenly coated. Set this crunchy topping aside to allow the flavors to meld while you assemble the casserole.
Step 4: Assemble the Casserole
Grease a 9×13 inch baking dish with a bit of dairy-free butter. Spread the sweet potato filling evenly across the bottom of the dish, smoothing it out with a spatula. Then, generously sprinkle the pecan topping over the sweet potato mixture, ensuring an even distribution that will bake up beautifully.
Step 5: Bake
Preheat your oven to 350°F. Place the assembled sweet potato casserole in the oven and bake for 35–40 minutes, or until the top is golden brown and bubbling. For an extra crispy topping, broil for 2-3 minutes at the end; just keep a close eye on it to prevent burning.

Sweet Potato Casserole Recipe FAQs
How do I select the best sweet potatoes for this recipe?
Absolutely! Look for sweet potatoes that are firm, smooth, and free from dark spots or bruises. The ones with a vibrant orange color will typically have the best flavor and sweetness. For a creamier texture, I often go for the medium-sized ones, as they often have more starch and less water content.
What’s the best way to store leftover sweet potato casserole?
You can store leftovers in an airtight container in the refrigerator for up to 5 days. Just make sure it’s sealed well to maintain that creamy texture! When you’re ready to enjoy it again, simply reheat in the oven or microwave, and you’ll be back to savoring the comforting flavors in no time.

What should I do if my sweet potato filling is too lumpy?
