Ingredients

• Sweet Potatoes (about 3 large): These are the star, obviously! I always go for the jewel yams, they’re so vibrant and sweet. Don’t cheap out on these, they’re the soul of this Southern Sweet Potato Casserole.
• Unsalted Butter (1 stick, melted): Gotta have butter, hon. It adds richness and helps everything come together. I tried olive oil once, and it just wasn’t the same. Stick with butter, trust me on this.

• Heavy Cream (1/2 cup): This is where the magic happens for that silky texture. I’m telling you, don’t use skim milk, just don’t. Heavy cream makes it luxurious, and we’re not counting calories today, okay?

• Light Brown Sugar (1/4 cup, packed): For that deep, molasses-y sweetness. I always pack it tight, otherwise, it feels like I’m cheating myself. Once I used granulated sugar, and it was just… flat. Brown sugar is a must!

• Vanilla Extract (1 tsp): A little splash of vanilla just brightens everything up. I always use good quality stuff, it makes a difference. My bottle once broke mid-pour, and everything smelled amazing but was a sticky mess!

• Ground Cinnamon & Nutmeg (1/2 tsp each): These spices are the warm hug of the casserole. I sometimes go a little heavier on the nutmeg, just because I adore that scent. It’s what makes this a real Southern Sweet Potato Casserole.

Instructions

Prep Those Spuds:

First things first, let’s get those sweet potatoes ready! I usually scrub them clean and then either boil them in a big pot of salted water until fork-tender, or, if I’m feeling lazy (which is often!), I’ll prick ’em and microwave them until soft. Boiling usually takes about 20-25 minutes. You want them squishy, not firm. This is where I always forget to salt the water, so don’t be like me, okay? Once they’re done, let them cool a bit so you can handle them without screaming. Peel off that skin, it should slip right off easily.

Mash It Up, Buttercup:

Now for the fun part: mashing! Pop those peeled sweet potatoes into a large mixing bowl. Add in the melted butter, heavy cream, brown sugar, vanilla extract, cinnamon, and nutmeg. Grab your trusty potato masher (or a fork, if you’re like me and can never find the masher). Mash, mash, mash until it’s super smooth and creamy. I once left a huge lump in, and my husband still teases me about it. Taste it here, hon! Adjust the sweetness or spices if you feel like it needs a little extra somethin’.

Make That Crunchy Topping:

While your sweet potato base is chilling, let’s whip up that glorious pecan topping for our Southern Sweet Potato Casserole. In a separate medium bowl, combine 1/2 cup of melted butter, 1/2 cup of light brown sugar, 1/4 cup of all-purpose flour, and 1 cup of chopped pecans. Stir it all together until it looks like a crumbly, buttery mess. This is the part that smells so good, I sometimes just want to eat it with a spoon. Don’t tell anyone, but I have! It’s the perfect contrast to the creamy potatoes.

Assemble Your Casserole:

Preheat your oven to 375°F (190°C). Grab a 9×13-inch baking dish and lightly grease it. Now, spoon all that beautiful, creamy sweet potato mixture into the prepared dish, spreading it evenly. Smooth it out with the back of a spoon or a spatula. Then, sprinkle that amazing pecan topping all over the top. Make sure it’s distributed nicely so every bite gets some crunch. I once overloaded one side, and it was a bit of a topping mountain learn from my mistakes!

Bake Until Bubbly:

Pop that dish into your preheated oven. Bake for about 25-30 minutes, or until the Southern Sweet Potato Casserole is heated through and the topping is golden brown and bubbly. Keep an eye on that topping, pecans can go from perfectly toasted to burnt in a blink! My oven runs hot, so I usually start checking around 20 minutes. You want it fragrant, bubbling at the edges, and the topping looking just irresistible.

Rest and Serve:

Once it’s out of the oven, I know it’s tempting to dig right in, but try to resist for a few minutes! Let the Southern Sweet Potato Casserole rest for about 5-10 minutes. This helps it set up a little, and prevents you from burning your tongue off (ask me how I know). The flavors meld, and it becomes even more glorious. It should look creamy, smell sweet and spiced, and that topping? Oh, it’s going to be perfectly crisp!

Southern Sweet Potato Casserole Storage Tips

So, you’ve got leftover Southern Sweet Potato Casserole? Lucky you! This dish actually holds up pretty well. Once it’s completely cooled, cover the baking dish tightly with plastic wrap or foil, or transfer it to an airtight container. It’ll keep in the fridge for 3-4 days. I’ve found that reheating it gently in the oven at 300°F (150°C) for about 15-20 minutes works best to maintain that texture. Microwaving it once made the topping a little soggy, and the creamy part got weirdly watery so don’t do that lol. If you freeze it, it can last up to 2-3 months, but the topping might lose some of its crunch, so I sometimes add fresh pecans if I’m freezing.

Southern Sweet Potato Casserole Ingredient Substitutions

Life happens, and sometimes you don’t have exactly what the recipe calls for. For the sweet potatoes, you can totally use canned sweet potato puree in a pinch, just make sure it’s unsweetened and drain it well. I tried that once, and it worked… kinda, but fresh is always better for the texture. If you’re out of heavy cream, whole milk will work, but it won’t be quite as rich. For the brown sugar, you can swap in maple syrup for a different kind of sweetness, but reduce the liquid slightly. If you don’t have pecans, walnuts are a good stand-in for the topping. I’ve used them before, and while it’s not quite the same, it’s still delicious and adds that necessary crunch to your Southern Sweet Potato Casserole.
