How To Bake Sweet Potatoes

Preheat oven to 400 degrees F. Rinse and scrub potatoes to remove and excess dirt. Pat dry then poke holes all over each potato using a fork.

Wrap each potato in a piece of aluminum foil, then place on a baking sheet lined with parchment paper or foil.

Bake potatoes for 45-60 minutes or until they are completely cooked through. You can test this by inserting a fork or knife into the center of a potato.

Key Ingredients

• Sweet potatoes: The star ingredient! I just get a 3 pound bag from the store that usually has about 10-11 small sweet potatoes.
• Milk: Any type of milk will work such as whole milk, low-fat milk, skim milk, and coconut milk. I use unsweetened almond milk.
• Coconut sugar: You could also use brown sugar instead.
• Egg: You just need one large whole egg to help bind the mixture together.
• Honey or pure maple syrup: Adds a natural sweetness without making the mixture too sweet.
• Vanilla extract: Enhances all of the flavors and adds a warm aroma.
• Cinnamon and nutmeg: Creates the warm spice flavor.
• Melted butter: Adds a creaminess to the potatoes but you could also use ghee. I use coconut oil.
• Crumble topping: Made with oats, chopped pecans, coconut sugar, cinnamon, whole wheat flour (you could also use gf flour, or all purpose flour, and syrup).

How To Make This Healthy Sweet Potato Casserole Recipe

Mash Sweet Potatoes: Once the baked potatoes have cooled, peel off the skin and place potatoes in a large bowl. Beat together with an electric mixer, potato masher, food processor, or a large fork until is looks mashed and almost smooth.

Add remaining ingredients: Add the rest of the filling ingredients and continue to beat together until combined. The mixture should be smooth at this point.

Our into casserole dish: Spray a 9×9 inch, 9×13 inch, or any casserole baking dish with nonstick cooking spray and pour in the filling. Spread with a spatula to create an even layer on top.

Make crumble oat topping: Combine all of the oat crumble topping ingredients together in a medium or small bowl and mix until all of the ingredients are combined.

Sprinkle and bake: Sprinkle the crumble on top of the sweet potato filling and bake for 35-40 minutes or until the oat crumble is a light golden brown. Cool for a few minutes before serving. Enjoy!

Recipe Tips & Variations

Vegan Sweet Potato Casserole: Completely omit the egg, use vegan butter, and use almond milk.

Additional Add-ins: Add pumpkin seeds, dates, and your favorite type of nuts. I love pecans in this recipe but you could also use hazelnuts, walnuts, and almonds.

Pumpkin flavor: Swap the cinnamon for pumpkin pie spice for even more fall flavors.

Smooth and creamy: If you want this casserole to be extra smooth and creamy, be sure to blend the sweet potato well until smooth.

Make Ahead

This Sweet Potato Casserole can easily be made ahead of time to make your dinner or holiday gathering less stressful. You can make this up to 2 days in advance.

Save 1 hour of time: Prepare the sweet potatoes by baking them the night before.

Make a day ahead: Bake the sweet potatoes, then make the sweet potato filling and crumble topping. Assemble the sweet potato casserole as if you were going to bake it but don’t. Wrap the casserole dish with plastic wrap or foil and place in the refrigerator until you are ready to bake it.

Leftovers & Storage

To-store: Place any leftovers in an airtight container or cover the casserole dish with plastic wrap. Store in the refrigerator for up to 4 days. This casserole tastes even better the next day! Simply reheat in the microwave or oven until warmed.

To-freeze: Store casserole in an airtight container or cover casserole dish tightly with plastic wrap and foil. Freeze for up to 3 months. Thaw on the counter for a few hours or overnight in the refrigerator. Heat in the microwave or oven.
