STEP ONE: Preheat your oven to 350 degrees F. As it heats, prepare a 1-quart baking dish by spraying it with cooking spray, and set it aside while you prepare your easy sweet potato casserole with pineapple and pecans.

STEP TWO: Be careful to drain the canned yams before you begin. Then, place them in a large mixing bowl to mash with a potato masher. You can also use a wooden spoon if you don’t have one. Add in your melted butter, brown sugar, egg, cinnamon, and salt and mix together thoroughly. Now, add your crushed pineapple.

STEP THREE: Spread the mixture evenly in the baking dish. Bake your pineapple sweet potato casserole uncovered for 30-minutes.

STEP FOUR: Take the dish out of the oven and add your marshmallows and chopped pecans on top. To get the crispy and golden topping you’re after, broil the casserole for 1 to 2 minutes, or until the marshmallows are browned to your liking. Enjoy!

How Do You Make Sweet Potato Casserole Not Runny?

I have definitely found myself with a runny casserole in the past, and it was usually due to leaving out the egg. You may feel strange adding an egg to this dish, but believe me, you do not want to skip it!

The egg acts as a binder for your sweet potato casserole with pineapple and pecans, and without it, you could end up with a runny mess.

Are Yams and Sweet Potatoes the Same Thing?

While you’ll often see sweet potatoes and yams used interchangeably, there is a difference between the two! 

Sweet potatoes are a root vegetable and, well, they look similar to regular potatoes and also feature the same texture. They are usually orange or purple in color. 

Yams are actually a lot rarer than sweet potatoes and quite difficult to find in the US. They feature a white interior. 

Now, I don’t want to confuse you, but this recipe calls for canned yams — which are actually canned sweet potatoes. You want to opt for the vegetable that’s orange on the inside!

How Do You Know When Sweet Potato Casserole is Done?

After you’ve cooked your sweet potato casserole with pineapple once for about 30 minutes, you need to take it out of the oven so that you can add your marshmallow and pecan topping.

Turn on your oven’s broiler and let it heat for a few minutes. Pop the casserole back in the oven, and keep an eye on it as it cooks. When the marshmallows turn a light golden brown color, you know you’re good to go.

Do You Peel Sweet Potatoes?

If you opt to use fresh sweet potatoes for this sweet potato and pineapple casserole recipe instead of canned yams (which you totally can, by the way! I have instructions over on my classic sweet potato casserole recipe), you should wash and peel them.

You aren’t required to peel sweet potatoes for every dish you use them in. For example, roasted or air-fried sweet potatoes are delicious with the skin on!

  1. Hi Samantha. If I make this for TG dinner, we have about 40 people coming. Can I double the recipe or would it be better to make 2 separate dishes??

  2. Can I make the casserole a day ahead of time and make/bake day prior and next day reheat and then broil with marshmallows to serve

  3. Sorry one more question do you recommend assembling and not cooking until the next day or cooking it /covering and reheating on the thanksgiving?

    • No worries! I know Thanksgiving is a stressful time with lots of cooking and baking! Yes, you can make the sweet potato casserole ahead of time by mixing the ingredients, placing it in the fridge, then baking it on Thanksgiving day. This would save time cooking it then reheating it again.
