Ingredients Notes

The magic of this Sweet Potato Casserole lies in its simple, wholesome ingredients. Here’s what you’ll need:

Sweet Potatoes: The star of the show! Look for firm, bright orange sweet potatoes for the best flavor and texture. They’ll provide the creamy base for the casserole.
Butter: Adds richness and depth to both the potato mixture and the topping. Use unsalted butter to control the saltiness.
Brown Sugar: Brings a warm sweetness to the dish. You can use light or dark brown sugar depending on your preference.
Milk: Helps create a smooth and creamy consistency in the potato filling. Whole milk works best, but you can substitute with plant-based milk if needed.
Eggs: Essential for binding the sweet potato mixture and giving it structure. Make sure they’re at room temperature for easy blending.
Vanilla Extract: Adds a subtle warmth that enhances the sweetness of the potatoes.
Pecans: These crunchy, buttery nuts are a highlight of the topping. Chop them coarsely for the best texture.
Marshmallows (optional): For those who love a classic touch, marshmallows can be added to the topping for extra gooey sweetness.

Special Equipment: A hand mixer or potato masher is key for achieving a smooth filling. You'll also need a 9x13-inch baking dish to assemble and bake the casserole.

How To Make This Sweet Potato Casserole

Creating this delightful casserole is easier than you might think. Follow these steps to bring this holiday favorite to life:

Prepare the Sweet Potatoes
Start by peeling and cubing your sweet potatoes. Boil them in a large pot of salted water until fork-tender, about 15-20 minutes. Drain well to remove excess moisture.
Mash and Mix
Using a hand mixer or potato masher, mash the sweet potatoes until smooth. Add butter, brown sugar, milk, eggs, and vanilla extract, mixing until well combined. Taste and adjust sweetness or seasoning if needed.
Assemble the Base
Spread the sweet potato mixture evenly into a greased 9x13-inch baking dish. Smooth the surface with a spatula to ensure an even layer.
Make the Topping
In a medium bowl, mix together butter, brown sugar, flour, and pecans to form a crumbly topping. Sprinkle this mixture generously over the sweet potato base. If using marshmallows, scatter them over the top for an extra layer of sweetness.
Bake to Perfection
Bake in a preheated oven at 350°F (175°C) for 25-30 minutes, or until the topping is golden brown and the casserole is heated through. Let it cool slightly before serving to allow the flavors to meld.

This dish comes together in under an hour, making it perfect for busy holiday schedules.

Storage Options

This casserole is as convenient as it is delicious! Here’s how to store it for later enjoyment:

Refrigerator: Transfer leftovers to an airtight container and store in the fridge for up to 3-4 days. Reheat individual portions in the microwave or the entire dish in the oven at 300°F until warmed through.
Freezer: You can freeze the casserole before baking. Assemble it in a freezer-safe dish, wrap tightly with plastic wrap and foil, and freeze for up to 2 months. Thaw overnight in the fridge before baking.
Make-Ahead Tip: Prep the casserole up to the topping step, cover, and refrigerate for up to 24 hours. Add the topping just before baking for the best results.

Variations and Substitutions

This recipe is wonderfully versatile, allowing you to tailor it to your taste or dietary needs. Here are some ideas:

Nut-Free Option: Swap the pecans for crushed pretzels or oats for a similar crunch without the nuts.
Lower Sugar Version: Reduce the brown sugar in both the filling and topping, letting the natural sweetness of the potatoes shine.
Gluten-Free Adaptation: Use gluten-free flour in the topping for a celiac-friendly version.
Vegan-Friendly Twist: Substitute butter with vegan butter, eggs with a flaxseed mixture, and milk with almond or oat milk.
Marshmallow Swap: Replace marshmallows with shredded coconut or additional pecans for a different take on the topping.
