Ingredients Notes

The beauty of this sweet potato casserole lies in its straightforward ingredients, each chosen to complement the natural sweetness of the potatoes. Here’s what you’ll need:

Sweet Potatoes – The star of the show. Choose large, firm sweet potatoes with a smooth skin. Roasting them enhances their natural sugars, resulting in a creamy, flavorful base.

Brown Sugar – Adds a deep, caramelized sweetness to both the filling and the topping. For a lighter flavor, you can substitute part of it with white sugar or maple syrup.

Butter – Unsalted butter brings richness to the casserole. It blends seamlessly into the sweet potatoes and helps create a perfectly crisp topping.

Eggs – These help bind the filling together, giving it structure while maintaining its creaminess.

Milk or Cream – For a luscious texture, a splash of whole milk or heavy cream is essential. Non-dairy options like almond milk also work beautifully if you’re catering to dietary preferences.

Pecans – The crunch from chopped pecans is the perfect contrast to the soft filling. Toast them lightly before adding to the topping for an extra layer of flavor.

Cinnamon and Nutmeg – These warm spices elevate the dish, adding depth and a touch of holiday magic.

If you have a food processor or electric mixer, it’ll make preparing the filling a breeze, but even a trusty potato masher will do the trick.

How To Make This Sweet Potato Casserole

Creating this sweet potato casserole is straightforward and satisfying. Here’s how to make it step by step:

1. Roast the Sweet Potatoes
Begin by preheating your oven to 375°F (190°C). Pierce 3-4 large sweet potatoes with a fork and place them on a baking sheet. Roast for 40-50 minutes, or until they’re tender and can be easily pierced with a knife. Once cool, peel off the skins.

2. Prepare the Filling
Mash the roasted sweet potatoes in a large mixing bowl. Add ⅓ cup of brown sugar, 4 tablespoons of melted butter, 2 eggs, ¼ cup of milk, 1 teaspoon of cinnamon, and a pinch of nutmeg. Mix until smooth and creamy. Spread the mixture evenly into a greased 9x13-inch baking dish.

3. Make the Pecan Topping
In a separate bowl, combine ½ cup of brown sugar, ¼ cup of melted butter, and 1 cup of chopped pecans. Stir until the mixture is evenly coated and crumbly.

4. Assemble and Bake
Sprinkle the pecan topping over the sweet potato mixture. Bake the casserole at 350°F (175°C) for 25-30 minutes, or until the topping is golden and crispy.

For an extra flourish, broil the casserole for 1-2 minutes at the end, keeping a close eye to avoid burning.

Storage Options

This sweet potato casserole stores beautifully, making it a fantastic make-ahead dish for busy holidays.

Refrigerator – Allow the casserole to cool completely, then cover it tightly with foil or plastic wrap. It will keep in the fridge for up to 4 days.

Freezer – For longer storage, freeze the casserole unbaked. Wrap it securely in plastic wrap and foil, and store it for up to 3 months. When ready to serve, thaw overnight in the fridge and bake as directed.

Reheating – To reheat leftovers, cover the casserole with foil and warm in a 350°F oven for 10-15 minutes. If the topping needs crisping, remove the foil for the last 5 minutes.

Variations and Substitutions

The versatility of this sweet potato casserole is one of its greatest strengths. Here are a few ideas to make it your own:

Marshmallow Topping – Swap the pecan topping for mini marshmallows. Sprinkle them over the casserole during the last 10 minutes of baking for a gooey, sweet finish.

Vegan Version – Replace the butter with a plant-based alternative, use almond or coconut milk, and substitute flaxseed eggs for a vegan-friendly option.

Gluten-Free Option – This recipe is naturally gluten-free, but double-check your ingredients, especially packaged items like spices, to ensure there’s no cross-contamination.

Coconut Lovers – Mix shredded coconut into the topping for a tropical twist that pairs beautifully with the sweet potatoes.

Spiced Up – Add a pinch of ground ginger or cardamom to the filling for a bolder flavor profile.
