Here in the south, potatoes are the number 1 side dish! White or sweet potatoes are the most popular choice. Other classic sides include Cornbread Dressing, Green Bean Casserole, Corn, Macaroni and Cheese, Squash Casserole, and Rolls. Every family is different and all are fabulous. Sometimes, my family eats Jambalaya for our holiday meal. So, there's no right or wrong.
The holidays are getting closer and I'm getting super excited about good food and good times with family and friends! Sweet potato casserole recipes have been around for a long, long time. There are many varieties from family to family. However, we happen to think this is the best recipe 🙂 Pair it with my Southern Cornbread Dressing and Creamy Squash Casserole for an authentic Southern meal!
Why We Love This Sweet Potato Casserole
Is sweet potato casserole a dessert or a side dish? Well, it is a side dish, but it is pretty darn sweet! The crispy brown sugar topping reminds me of a pecan praline. For this reason, just a spoonful should be all you need 🙂 This casserole makes 9 servings, but with smaller portions, you could get a couple more out of it.
As mentioned above, there are SO many variations for this recipe. Some have marshmallows and some have raisins. Some have sweet potato slices and some have mashed sweet potatoes. Some use fresh ingredients and some use canned. So if you're undecided about which one to choose, I highly urge you to give this recipe a try!

Frequently Asked Questions
So, these two are totally different root vegetables! First, the skins are quite different. Yams have a dark, bumpy, tough skin while sweet potatoes have reddish-orange, thin, smoother skin. The flesh differs as well. Sweet potatoes have a smooth, sweet flesh while yams have a more fibrous non-sweet flesh. For these reasons, I would not use yams for this recipe.
Make the casserole and the topping the day before you plan to eat it. Keep the topping in a separate container. Store both in the refrigerator. Right before you bake the casserole, add the topping and bake as directed.
It freezes very well! Make the casserole but don't add the pecan topping. Tip - use an oven-to-freezer container. Let it cool completely. Wrap in plastic, then wrap in aluminum foil. Freeze for up to one month. When ready to bake, thaw in the refrigerator. When ready to bake, make the pecan topping, sprinkle on top of the casserole, and bake as directed.
Storing Leftovers in the Refrigerator
Store leftovers in airtight containers for up to 3 days. I like to use BPA-free glass containers with locking lids. Check out this 18-piece set of glass food storage containers with locking lids. Available now on Amazon.
Expert Tips
If you're running short on time, you can use canned sweet potatoes). Buy three 16-ounce cans, and discard all the liquid. Mash them up and proceed with the recipe card instructions.
