I love sweet potatoes but I have a family that really doesn’t care for this delicious & healthy tuber. But what’s Thanksgiving without a sweet potato casserole? I know, right?!

So a number of years ago, we won’t get into how many that is, I set about to make a recipe that would get everyone in my family excited about eating sweet potatoes. It took a few tries but I finally landed on just the right combination of sweetness and spice, and of course plenty of crumbs, that made my family crazy about sweet potatoes.

I have to warn you that this easy sweet potato casserole is addictive! It tastes like you are enjoying dessert for dinner, a la sweet potato pie. It has creamy mashed sweet potatoes, combined with butter, cinnamon and sugar then it’s loaded with a sugar-pecan crumb mixture that is out of this world.

Easy Thanksgiving side dish to make ahead and freeze

One of the nice things I love about this casserole, is the ability to make it ahead of time and freeze it until the day before Thanksgiving. Let it thaw overnight in the refrigerator then cook as directed. No need to worry about last minute prep with this side dish. And it can be cooked right beside your turkey! Just another easy way to take the stress out of the holidays.

Frequently asked questions about Sweet Potato Casserole

Can you freeze this sweet potato casserole?

Absolutely! To make it ahead of time, follow the instructions up to the cooking stage. Let cool slightly, cover tightly, then freeze. To make, thaw overnight in the refrigerator then bake as directed.

How long does this casserole last?

Once cooked, it will stay fresh in the refrigerator for 5 days. Although I can’t verify that because ours never lasts that long! lol

Can I reheat this easy to make casserole?

Sure can! The best way to reheat the casserole is in the oven in order to keep the crumb topping crunchy.  Place in a baking dish, cover and bake in a 350 degree oven for 15-20 minutes. It can also be done in the microwave, reheating for 3-5 minutes. However, the crumbs will not be crunchy using this method.
