What I Love About Creamy Sweet Potatoes
- The recipe is perfect for the holidays and can be made a day in advance.
- It is a balance of sweet and savory and provides a great textural contrast with the creamy sweet potatoes and crunchy candied pecans.
- It is versatile. You can add the marshmallows or leave them off and enjoy the brown sugar topping.

Make Ahead Tips
If you want to make the recipe ahead of time, mix the sweet potato base ingredients together and add them to the casserole dish. Cover with plastic wrap and refrigerate. When you are ready to cook the dish, mix up the toppings, sprinkle them on top, and bake.
Step-By-Step Instructions


Drain the juice off the canned yams and add them to a large mixing bowl. Pour the sugar on top of the yams. Next, add the eggs, milk, salt, vanilla extract, and melted butter to the bowl and mix well.


Once you have the first part mixed up, grease a 9-inch by 9-inch casserole dish. Pour the mix into the prepared baking dish. Stop here if you’d like to refrigerate it and save it until the next day. If not, continue with the sweet potato casserole. For the topping, add some brown sugar to the bowl. Next, add the flour, pecans, and melted butter. Mix until the pecans are covered.


Sprinkle the pecan topping all over the sweet potato mixture and bake for 40-45 minutes. Once you bake the sweet potato casserole, sprinkle the marshmallows on top.
Tips
- Be sure not to pour the hot melted butter over the eggs, or it might cook them a little – speaking from experience. I’ve done it several times.
- I buy the mini marshmallows, but any size will do. I use about half a bag of marshmallows and spread them over the top.
- The marshmallows may deflate a bit after they sit for a few minutes, but they won’t taste any less AMAZING!
- When you cook the marshmallows, start off with five minutes because they cook fast. Keep an eye on them and stay near the oven because they can burn fast, too.

This is the best sweet potato casserole recipe. The topping creates a crunchy pecan layer that is out of this world.

My brother-in-law didn’t like marshmallows (whaaat?), so I left them off of his little section, and he still loved the recipe.
Leftovers and Storage
If you have any leftovers you can save them in an airtight container in the refrigerator. They are good up to a week.
- Oven – turn it on 300 degrees, cover with aluminum foil and cook for about 15 minutes or until the casserole is heated through.
- Microwave – Scoop some on a microwave-safe plate and cover with a paper towel. Microwave on medium power for about 1-1/2 to 2 minutes or until hot.
