Sweet Potato Casserole Ingredients

This is the best sweet potato casserole to make at home because it’s super simple with just 5 pantry staple ingredients! Here’s what you’ll need to make your own canned sweet potato casserole.

Canned Sweet Potatoes: This shortcut ingredient saves time without sacrificing flavor—canned sweet potatoes are already peeled, washed, pre-cooked and sometimes cut into small sizes to help reduce prep time! Don’t worry—they taste just as good as fresh sweet potatoes (if not even better).

Melted Butter: Not only is this ingredient a must-have when it comes to flavor—but the melted butter also acts as a binder (and helps keep the toppings in place).

Brown Sugar: Don’t skip the brown sugar! With its delicate caramel-like flavor, it brings out the natural sweetness of your sweet potatoes beautifully.

Salt: Balance out the sweetness with just the right amount of salt. With only a half teaspoon, it won’t feel like much, but this small yet mighty ingredient will really highlight the savory flavors in your casserole.

Marshmallows: Who could forget the soft, fluffy, and perfectly gooey marshmallows? We use large ones in this recipe, but you can substitute mini marshmallows if you’d like. To make this swap, sprinkle 1½ cups of mini marshmallows over your assembled casserole and bake as directed. Keep an eye on the mini ‘mallows and make sure they don’t start browning too quickly!

What Are the Best Sweet Potatoes for Sweet Potato Casserole?

There are hundreds of varieties of sweet potatoes, ranging in color from white to deep orange and even purple. Here are some types you might come across, and what they’re best used for.

Beauregard:This is the most common variety of sweet potato. Identified by its dusky red skin, this versatile spud is great for mashing, baking, boiling, and frying. It’s a popular choice for sweet potato casserole due to its classic sweet taste!

Jewel: This sweet potato is another of the most common types. With a copper skin and deep orange flesh that’s moist, tender, and moderately sweet when cooked, the Jewel is also a go-to choice for this sweet potato casserole.

Garnet: Named for their red-purple skin, Garnets have an orange flesh with a moist, heavy, and pumpkin-like quality when baked. They’re a popular choice for sweet potato pie.

Covington: These rose-skinned sweet potatoes have a super sweet orange flesh that’s best suited for side dishes and desserts. The Covington is a major favorite in the South!

O’Henry: Slightly less sweet and a bit denser and heavier than other varieties when baked, the cream-colored O’Henry sweet potato tastes best in soups and stews.

Purple: Purple sweet potatoes are known for their firm, lightly sweet flesh with a slight tartness that lends itself well to highly seasoned, roasted savory dishes. We’d recommend choosing a sweeter option for this sweet potato casserole .

Can I Use Fresh Sweet Potatoes for This Sweet Potato Casserole Recipe?

This easy sweet potato casserole recipe uses canned sweet potatoes as a helpful shortcut for busy cooks—but if you’ve got more time on your hands, you can start with whole sweet potatoes instead! Keep in mind that you’ll need to pre-cook fresh sweet potatoes before proceeding with this recipe. Check out our tips above on the sweet potato varieties we’d recommend using for sweet potato casserole.

The microwave comes in handy here. Just pierce your sweet potatoes with a fork and cook them in the microwave for 8 to 12 minutes, turning them over once halfway through the cooking time. Let them sit for one minute and then add your seasonings!

How Long Should I Bake Sweet Potato Casserole For?

This is the best sweet potato casserole for those short on time—it only needs 25 to 30 minutes in a 350°F oven. When your casserole is done, the sweet potatoes should be fully heated through, and the marshmallows should be lightly browned. If the marshmallows start browning too quickly, loosely cover the baking dish with tinfoil for the last 10 minutes of baking time. The shiny nature of foil deflects heat, slowing down the browning process of ingredients high in sugar or fat!
