Step‑by‑Step Instructions for Sweet Potato Casserole
Step 1: Cook Sweet Potatoes
Begin by scrubbing the sweet potatoes clean. For the Instant Pot method, place them on a trivet with 1 cup of water, seal the lid, and cook on high pressure for 15 minutes. Allow a natural release for 10 minutes before cooling and peeling. Alternatively, preheat your oven to 425°F, poke holes in the sweet potatoes, and bake for 45-50 minutes until tender. Let them cool before peeling.
Step 2: Prepare the Pecan Topping
In a medium bowl, combine the chopped pecans, brown sugar, and a pinch of cinnamon. Mix well to ensure even distribution of the ingredients. Set the bowl aside so the flavors can meld together while you prepare the filling for the sweet potato casserole.
Step 3: Make the Filling
Once the sweet potatoes are peeled, place them in a large mixing bowl and mash them until smooth. Add in the dairy-free butter, maple syrup, coconut milk, gluten-free flour, cinnamon, and vanilla extract. Mix thoroughly until all ingredients are well combined and creamy, creating a delightful filling for your sweet potato casserole.
Step 4: Assemble the Casserole
Preheat your oven to 350°F. Lightly grease a 9″x13″ baking dish to ensure your sweet potato casserole lifts out easily when baked. Spread the creamy sweet potato filling evenly into the dish, making sure it’s smooth and level. Then, sprinkle the prepared pecan topping generously over the filling, creating a lovely crunch on top.
Step 5: Bake
Place the casserole into the preheated oven and bake for 35-40 minutes, or until the topping is golden brown and the filling is heated through. For extra crispiness, broil on high for an additional 2-3 minutes, keeping a close eye on it to prevent burning. This final touch adds a delicious contrast to your sweet potato casserole.
Step 6: Cool and Serve
Once baked to a golden perfection, remove the casserole from the oven and let it cool for a few minutes. This cooling period allows the layers to set, making it easier to serve. Enjoy warm as a comforting side dish or a delightful dessert, showcasing the delicious harmony of flavors in your gluten-free sweet potato casserole.

How to Store and Freeze Sweet Potato Casserole
Fridge: Store any leftover sweet potato casserole in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through.

Gluten-Free Sweet Potato Casserole Recipe FAQs
How do I choose the right sweet potatoes for my casserole?
Absolutely! Look for medium-sized sweet potatoes that are firm to the touch and free from dark spots or blemishes. These will yield a creamy base for your casserole. Avoid any that feel soft or have wrinkles, as they may be overripe.
How should I store leftover sweet potato casserole?
Very simply! You can store any leftovers in an airtight container in the refrigerator for up to 3 days. Just reheat gently in the oven or microwave until warmed through. For best quality, let it cool completely before sealing.
Can I freeze sweet potato casserole for later use?
Yes, you can! To freeze, wrap the uncooked casserole tightly in plastic wrap followed by a layer of aluminum foil. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy it, thaw it overnight in the fridge and bake at 350°F for 30-40 minutes until it’s hot and the topping is golden brown.
What should I do if my casserole turns out too watery?
If you find your casserole is too watery, a little bit of gluten-free flour can help absorb excess moisture. Alternatively, try mixing it during the filling stage to ensure everything is combined well. Be sure to mash the sweet potatoes thoroughly to avoid lumps, which can also contribute to a soupy consistency.
Can I make this casserole dairy-free for my guests with lactose intolerance?
Absolutely! This recipe is already dairy-free thanks to the use of dairy-free butter and coconut milk. Always double-check labels to ensure they meet dietary requirements. If you’re cooking for pets, avoid adding any ingredients (such as nuts or sugars) that can be harmful to their health.
What type of pecans should I use for the topping?
I recommend using fresh, whole pecans for the best flavor and crunch! You can finely chop them for a finer texture or leave them in larger pieces for added crunch. Feel free to substitute with walnuts or almonds if you prefer a different nutty flavor.
