How To Make Gluten-Free Sweet Potato Casserole

Step 1: Warm Up the Oven

Turn the oven to 375°F. This will ensure your casserole bakes perfectly with a crispy topping.

Step 2: Prepare Sweet Potatoes

Peel the sweet potatoes and cut them into chunks. Boil in water until they’re soft and easily pierced with a fork.

Step 3: Create Creamy Sweet Potato Base

Drain the cooked sweet potatoes and transfer to a mixing bowl. Mash thoroughly with:
  • Coconut milk
  • Maple syrup
  • Vanilla extract
  • Ground cinnamon
  • Ground nutmeg

Blend until smooth and silky.

Step 4: Arrange the Base

Transfer the sweet potato mixture into a baking dish, spreading it evenly with a spatula.

Step 5: Craft the Crunchy Topping

In a separate bowl, combine:
  • Gluten-free rolled oats
  • Chopped pecans
  • Brown sugar
  • Sea salt
  • Melted coconut oil

Mix ingredients until they form a crumbly texture.

Step 6: Add the Topping

Sprinkle the pecan-oat mixture over the sweet potato base, covering the entire surface.

Step 7: Bake to Golden Perfection

Place the casserole in the preheated oven.

Bake for 25-30 minutes until the top turns golden brown and looks slightly crispy.

Step 8: Serve and Savor

Remove from the oven and let cool for a few minutes.

Serve warm and enjoy the delightful blend of creamy sweet potatoes and crunchy topping.

Tips For Flavorful Gluten-Free Sweet Potato Casserole

  • Swap regular oats for certified gluten-free oats to ensure the dish is completely safe for those with gluten sensitivities.
  • Use pure maple syrup for a richer, more natural sweetness that complements the sweet potatoes' natural flavor.
  • Choose fresh, firm sweet potatoes with smooth skin for the best texture and most consistent mashing results.
  • Adjust the spice level by increasing or decreasing cinnamon and nutmeg to suit personal taste preferences.
  • Let the casserole cool for 10-15 minutes after baking to allow the topping to set and become perfectly crispy.

Flavorful Twists For Gluten-Free Sweet Potato Casserole

  • Vegan Sweet Potato Delight: Replace coconut milk with almond milk and use maple syrup as a vegan-friendly sweetener. Swap pecans with crushed walnuts for extra crunch.
  • Keto-Friendly Sweet Potato Alternative: Substitute sweet potatoes with mashed cauliflower, use monk sweetener instead of brown sugar, and add almond flour to the topping for a low-carb version.
  • Paleo Sweet Potato Casserole: Use ghee instead of coconut oil, replace oats with chopped almonds, and add a dash of cinnamon for warmth. Ensure all ingredients are paleo-compliant.
  • Nut-Free Comfort Casserole: Remove pecans and replace with sunflower seeds. Use coconut sugar instead of brown sugar and keep the same creamy sweet potato base.

What To Serve With Gluten-Free Sweet Potato Casserole

  • Cozy Holiday Centerpiece: Create a festive display by serving the casserole in a rustic ceramic dish garnished with fresh rosemary sprigs and whole pecans around the edges.
  • Breakfast Remix: Transform leftovers into a morning treat by adding a dollop of Greek yogurt and a sprinkle of extra cinnamon on top for a decadent breakfast option.
  • Thanksgiving Sidekick: Pair this gluten-free sweet potato casserole with roasted turkey, cranberry sauce, and green beans for a complete traditional meal that everyone can enjoy.
  • Dessert Upgrade: Serve with a small scoop of dairy-free vanilla ice cream or whipped coconut cream for an extra indulgent touch that complements the warm spices.

How To Store Gluten-Free Sweet Potato Casserole

  • Store leftovers in an airtight container in the refrigerator for up to 4 days, keeping the casserole's texture and flavor intact.
  • Cover the casserole tightly with plastic wrap or aluminum foil to prevent moisture loss and refrigerate promptly after cooling to room temperature.
  • Reheat individual portions in the microwave for 1-2 minutes, stirring halfway through to ensure even heating and maintain the creamy consistency.
  • For best results, reheat the entire casserole in a preheated oven at 350°F for 15-20 minutes, covering with foil to prevent the topping from burning while restoring its crispy texture.
