Ingredients Needed for the Recipe

Gathering your ingredients is the first step to creating this cozy masterpiece. Here’s what you’ll need to have on hand:

• Sweet Potatoes: 3 pounds, which is about 6 medium-to-large ones. You’ll peel and cube them before boiling.
• Brown Sugar: ½ cup, packed. Light or dark works, but dark brown sugar offers a deeper, more caramel-like flavor.
• Butter: ⅓ cup, softened. Salted butter is perfect here, adding a lovely richness.
• Vanilla Extract: Just ½ teaspoon to add a warm, aromatic depth to the potatoes.
• Pecans: ¾ cup, chopped and divided. We’ll use some in the base and some for the topping.
• Cinnamon: ¼ teaspoon, or honestly, to your taste. It’s the warm spice that makes it sing.
• Salt and Black Pepper: To taste. A little pepper enhances the sweetness in a surprising, wonderful way.
• Miniature Marshmallows: 2 cups. These are for that iconic, toasty, pillowy top layer we all love.

What’s the Best Sweet Potato to Use?

You might see different varieties at the store, and it can be a little confusing. For this casserole, the classic orange-fleshed sweet potatoes, sometimes labeled as yams, are your best bet. Their vibrant color and naturally sweet, moist flesh create the most luxurious and beautiful mashed base.

When selecting them, look for firm potatoes that feel heavy for their size, with smooth, unblemished skins. You can absolutely use canned sweet potatoes for a shortcut, just be sure to drain them very, very well to avoid a watery casserole. But if you have the time, fresh sweet potatoes really do make a noticeable difference in both flavor and texture.

How to make Sweet Potato Casserole?

Preheat and Prep Your Pan

Start by preheating your oven to 375°F (190°C). This ensures it’s perfectly hot and ready when your casserole is assembled. Take a 9×13-inch baking dish and give it a light coating of butter or a quick spritz of non-stick spray.

Cook the Sweet Potatoes

Place your peeled and cubed sweet potatoes into a large pot of boiling, salted water. Let them simmer for about 15 minutes, or until they are completely tender when pierced with a fork. You want them soft enough to mash without any resistance.

Drain and Combine

Carefully drain the hot water from the pot. Now, for the fun part: in that same warm pot, or in a large mixing bowl, add the cooked sweet potatoes, brown sugar, softened butter, cinnamon, vanilla, and a good pinch of salt and pepper.

Mash to Perfection

Using a potato masher, blend everything together until it’s mostly smooth but still has a bit of pleasant texture. If you prefer an ultra-silky, fluffy consistency, a hand mixer works beautifully here. Just don’t over-mix, or the potatoes can become a bit gluey.

Fold in the Goodness

Stir in half of your chopped pecans. This little trick adds a wonderful nutty surprise throughout the entire casserole, not just on top. Now, spread this gorgeous sweet potato mixture evenly into your prepared baking dish.

Add the Iconic Topping

This is where the magic happens. Evenly sprinkle the miniature marshmallows and the remaining pecans over the entire surface. Don’t be shy—this is what creates that beautiful, golden, crunchy, and gooey crown.

Bake Until Golden

Place the dish in your preheated oven and bake for 25-30 minutes. You’re waiting for the marshmallows to turn a deep, toasty golden brown and for the sweet potatoes to be bubbly around the edges. Let it rest for a few minutes before serving, as the inside will be incredibly hot.

Can I Make a Topping Without Marshmallows?

Absolutely! While the marshmallow version is a classic for a reason, not everyone is a fan. A fantastic alternative is a buttery streusel or crumble topping. Simply mix together flour, rolled oats, more brown sugar, and cold cubed butter with your fingers until crumbly, then mix in the pecans.

You would sprinkle this over the sweet potato base and bake as directed. The result is a delightful, crisp, and cookie-like topping that provides an amazing textural contrast. It’s a more “grown-up” version that is equally beloved and just as simple to prepare.

Tips

For the fluffiest mashed sweet potatoes, be sure to drain them thoroughly after boiling. Let them sit in the colander for a minute or two to steam off any excess water, which can make your casserole base runny.

If you’re using unsalted butter, don’t forget to be a bit more generous with the salt you add to the potato mixture. That pinch of salt is crucial, as it works to heighten all the other flavors and balance the sweetness perfectly.

To prevent a sticky situation when mashing, add your softened butter first. The fat will coat the potato pieces, making them less likely to become gummy as you mash them into submission. It’s a small step with a big payoff.

How Can I Make This Dish Ahead of Time?

This is the ultimate make-ahead dream! You can prepare the sweet potato base completely, spread it into your baking dish, cover it tightly, and refrigerate it for up to two full days. Just be sure to store the marshmallows and pecans for the topping in a separate bag or container at room temperature.

When you’re ready to bake, take the dish out of the refrigerator about 30 minutes before it goes in the oven to take the chill off. You may need to add a few extra minutes to the baking time since you’re starting with a cold base. This trick is a total game-changer for stress-free holiday cooking.

Storing and Reheating Your Leftovers

If you’re lucky enough to have leftovers, they store beautifully. Just place them in a sealed container in the refrigerator for up to 5 days. To reheat, the microwave is your fastest friend for warming the interior quickly and easily.

For that freshly-baked feel, especially with the topping, pop a single serving in an oven-safe dish under the broiler for just a minute or two. Watch it closely, though, as the marshmallows can go from perfectly toasted to completely charred in a flash. It’s a wonderful way to bring back that first-day magic.
