Here’s everything you’ll need to create this crowd-pleaser:

  • 3 pounds sweet potatoes (peeled and cut into cubes): The star ingredient providing natural sweetness and creamy base texture.
  • ½ cup packed brown sugar: Adds a deep, caramel-like sweetness that enhances the potatoes perfectly.
  • ⅓ cup softened butter: Brings richness and smoothness to the mash.
  • ½ teaspoon vanilla extract: A subtle hint of warmth that complements the sweetness beautifully.
  • ¾ cup chopped pecans (divided): For a toasty crunch and nutty contrast layered inside and on top.
  • ¼ teaspoon cinnamon (or to taste): Adds cozy spice that elevates the sweet potatoes.
  • Salt and black pepper (to taste): Balances the sweetness and enhances all flavors.
  • 2 cups miniature marshmallows: The crowning glory to melt, toast, and add a whimsical touch of sweetness.

How to Make Sweet Potato Casserole with Pecans and Marshmallows Recipe

Step 1: Preheat and Prepare

Start by heating your oven to 375°F and generously grease a 9 x 13-inch baking pan. This ensures your casserole won’t stick and will bake evenly with a golden crust on top.

Step 2: Cook the Sweet Potatoes

Place the peeled and cubed sweet potatoes in a pot of boiling water and let them simmer until they’re fork-tender, which usually takes about 15 minutes. This step is essential to achieve that perfect soft texture for mashing.

Step 3: Mash and Flavor

Drain your sweet potatoes and transfer them to a large bowl or back into the pot used for boiling. Then add in the brown sugar, softened butter, cinnamon, vanilla extract, salt, and pepper. Mash everything together until you get a smooth, luscious mixture. The blend of these ingredients creates the signature flavor and velvety texture of this casserole.

Step 4: Mix in Pecans and Layer

Fold half of the chopped pecans gently into your mashed sweet potatoes. This adds a subtle crunch throughout. Spread the mixture evenly in your prepared baking dish, setting the stage for the final touches.

Step 5: Top with Marshmallows and Pecans

Sprinkle the remaining chopped pecans over the mashed potatoes, then generously cover with miniature marshmallows. This topping will bake into a golden, gooey layer that’s both visually inviting and delicious.

Step 6: Bake to Perfection

Bake the casserole for about 25 minutes or until the marshmallows turn a beautiful golden brown and the casserole is heated all the way through. This is when the aroma will fill your kitchen and the anticipation begins!

Side Dishes

This casserole pairs wonderfully with savory mains like roasted turkey, glazed ham, or herb-crusted chicken. Its sweet richness also balances well with crisp green salads or steamed vegetables, adding diversity and vibrancy to your meal.

Creative Ways to Present

For an extra bit of fun, try serving individual portions in small ramekins topped with a single toasted pecan and a few mini marshmallows broiled just before serving. It’s perfect for a festive gathering and lets each person enjoy their own personal serving of this comfort food classic.

Make Ahead and Storage

Storing Leftovers

You can store any leftover Sweet Potato Casserole with Pecans and Marshmallows Recipe in an airtight container in the refrigerator for up to 4 days. To keep the marshmallows from becoming too sticky, consider adding a layer of foil between the casserole and the container lid.

Freezing

This casserole freezes beautifully. Wrap it tightly with plastic wrap and then aluminum foil to prevent freezer burn, and store it for up to 3 months. When you’re ready to enjoy it, thaw it overnight in the fridge before reheating.

Reheating

Reheat your leftovers in a preheated oven at 350°F, covered loosely with foil to avoid excessive browning. Warm for about 20 minutes or until heated through, then remove the foil and broil for a minute or two if you want to refresh the golden marshmallow topping.
