Step‑by‑Step Instructions for Sweet Potato Casserole Recipe
Step 1: Cook the Sweet Potatoes
Begin by preparing your sweet potatoes, the base of this sweet potato casserole recipe. If using an Instant Pot, place the scrubbed potatoes on a trivet, add 1 cup of water, seal the lid, and cook on high pressure for 15 minutes. Perform a quick release after a 10-minute natural release. For oven cooking, preheat to 425°F, poke holes in the potatoes, and bake for 45-50 minutes until fork-tender. Allow them to cool slightly, then peel off the skins.
Step 2: Prepare the Pecan Topping
While the potatoes cool, prepare the crunchy pecan topping. In a mixing bowl, combine chopped pecans, a sprinkle of brown sugar, dairy-free butter, and a dash of cinnamon. Mix until the ingredients are thoroughly incorporated, creating a crumbly texture. Set aside this mixture to allow the flavors to meld while you move on to the next step.
Step 3: Combine the Casserole Filling
In a large bowl, mash the peeled sweet potatoes using a hand mixer until they are smooth and creamy. Then, blend in the dairy-free butter, brown sugar, gluten-free flour, and cinnamon, ensuring everything is well combined. The mixture should be smooth and slightly fluffy, creating a perfect base for your sweet potato casserole recipe.
Step 4: Assemble the Casserole
Grease a 9×13-inch baking dish to prevent sticking. Pour the sweet potato mixture into the dish, spreading it evenly with a spatula. Smooth the top to create a nice surface for the pecan crumble. Make sure that the filling is tightly packed without any major air pockets, which helps in achieving a creamier texture during baking.
Step 5: Add the Pecan Topping
Sprinkle the pecan topping generously over the sweet potato mixture, ensuring even coverage. Preheat your oven to 350°F, then bake the casserole for 35-40 minutes. Look for a golden-brown color on the topping and a slight bubbling around the edges to signal that it’s done. If you desire an extra crispy finish, broil for 2-3 minutes more, watching closely to prevent burning.
Step 6: Serve the Casserole
Once baked, remove the sweet potato casserole from the oven and let it cool for about 10 minutes. This allows the layers to set slightly, making it easier to serve. Scoop out generous portions and enjoy this delightful dish, perfect for sharing with family and friends at your next holiday gathering.

Sweet Potato Casserole Recipe FAQs
How do I select the best sweet potatoes?
Absolutely! When choosing sweet potatoes for your casserole, look for ones that are firm, smooth-skinned, and free from any dark spots or blemishes. Smaller to medium-sized potatoes tend to be sweeter. If you find some with a little dirt, don’t worry—just give them a good scrub before cooking!
What is the best way to store leftovers?
Very good question! Store any leftover sweet potato casserole in an airtight container in the refrigerator for up to 3 days. To keep that delightful flavor intact, simply reheat in the oven at 350°F for about 20-25 minutes. This way, you can enjoy the creamy texture and crunchy topping just like when it was freshly made.
Can I freeze sweet potato casserole?
Absolutely! You can freeze portions of your casserole for later enjoyment. Just wrap individual pieces tightly in plastic wrap, then place them in a freezer-safe container. It will last for up to 3 months. When you’re ready to enjoy, thaw overnight in the fridge and reheat in the oven as mentioned earlier.
What should I do if my casserole turns out watery?
No worries! If your casserole ends up watery, it could mean the sweet potatoes retained too much water during cooking. To avoid this, make sure they are well-drained after cooking. If you find yourself with a watery casserole, you can gently bake it uncovered in the oven for an additional 10-15 minutes to help evaporate the excess moisture.
Is this casserole suitable for kids or those with allergies?
Yes, this sweet potato casserole recipe is gluten-free and dairy-free, making it a great option for little ones and guests with dietary restrictions. However, always double-check the labels of any pre-packaged ingredients to be sure they don’t contain allergens. I often recommend using nut-free alternatives if needed, such as sunflower seeds in place of pecans!
