Ingredients Notes

The beauty of this sweet potato casserole lies in its simple, wholesome ingredients. Each one brings something special to the dish.

Sweet Potatoes: The star of the show! Choose large, firm sweet potatoes with smooth skins. They provide the creamy, naturally sweet foundation for the casserole.

Brown Sugar: This adds a rich, caramel-like sweetness to the mashed sweet potatoes. Light or dark brown sugar both work, depending on your flavor preference.

Butter: For that signature richness, unsalted butter is ideal. It blends beautifully into the filling and creates a luscious topping.

Cinnamon and Nutmeg: These warm spices elevate the dish, giving it a cozy, holiday vibe. Freshly grated nutmeg is especially aromatic if you have it on hand.

Pecans: A classic topping ingredient, pecans add crunch and a toasty flavor that contrasts perfectly with the creamy base. Chop them coarsely for a rustic finish.

If you don’t already own a potato masher or hand mixer, either will be helpful to create a smooth sweet potato mash. A sturdy baking dish is essential, preferably glass or ceramic, to ensure even cooking.

How To Make This Sweet Potato Casserole

Making this casserole is as rewarding as it is simple. Follow these steps to create a show-stopping side dish that’s sure to impress.

Start by prepping the sweet potatoes. Peel and chop them into chunks, then boil them in a large pot of salted water until they’re fork-tender, about 15-20 minutes. Drain them well to avoid excess moisture in your casserole.

Mash the cooked sweet potatoes until they’re smooth and creamy. You can use a potato masher for a rustic texture or a hand mixer for a fluffier result. Mix in the brown sugar, melted butter, cinnamon, nutmeg, and a pinch of salt. Don’t forget to taste and adjust the sweetness or spice to your liking.

Transfer the sweet potato mixture to a greased baking dish, spreading it evenly with a spatula. This creates the perfect canvas for the topping.

For the topping, combine chopped pecans, brown sugar, and a bit of melted butter. Sprinkle it generously over the sweet potato base, ensuring an even layer for maximum crunch.

Bake the casserole at 350°F (175°C) for 25-30 minutes, or until the topping is golden and bubbly. The aroma will let you know it’s ready—sweet, nutty, and utterly tempting.

Storage Options

This casserole is perfect for make-ahead planning, making it a stress-free addition to your holiday menu.

To store leftovers, cover the baking dish tightly with plastic wrap or transfer portions to an airtight container. It will keep in the refrigerator for up to four days.

If you’d like to prepare it ahead, assemble the casserole (without baking) and refrigerate for up to 24 hours. When you’re ready to serve, bring it to room temperature before baking as directed.

For longer storage, you can freeze the unbaked casserole. Wrap it tightly with aluminum foil and freeze for up to two months. Thaw overnight in the fridge before baking.

Reheat leftovers in the oven at 325°F (160°C) until warmed through, or use the microwave for individual portions.

Variations and Substitutions

One of the best things about sweet potato casserole is its adaptability. Here are a few ways to make it your own:

For a vegan version, swap the butter for a plant-based alternative and use coconut milk or almond milk to replace any dairy.

If you prefer less sugar, reduce the brown sugar in the filling or topping. The natural sweetness of the sweet potatoes still shines through.

To make it nut-free, replace the pecans with crushed pretzels or rolled oats mixed with a touch of melted butter and cinnamon.

For an indulgent twist, add mini marshmallows to the topping during the last 10 minutes of baking. They’ll melt into a gooey, golden layer that’s irresistible.

Experiment with different spices, like ginger or cloves, to add a unique flavor profile. You can also mix in a splash of orange juice for a bright, citrusy note.

With its creamy base and irresistible topping, this sweet potato casserole is destined to become a family favorite. Whether you serve it at Thanksgiving or as a comforting side dish any time of year, you can’t go wrong. So grab your apron and let the magic begin!
