How to Cook Sweet Potatoes

There are a variety of cooking methods for sweet potatoes, all of which are delicious.

Depending on the dishes you are serving with the potatoes, you can either boil, bake, or fry them. These are the three most common ways of cooking them, and there is no way that you can go wrong with these methods!


The first way that you can cook sweet potatoes is by boiling them. Boiling sweet potatoes is extremely easy, and there is no way that you can mess it up. If you have not had a lot of experience in the kitchen, then you may want to start off with boiling the potatoes just to play it safe.

Boiling sweet potatoes is fairly simple. The first thing you need to do is to wash your sweet potatoes to remove any dirt. Next, you need to stab each sweet potato with a fork 7-8 times, making sure there are a few holes on each side.

This might seem silly, but it allows steam to escape the sweet potato while it is cooking. This is important because if the steam is unable to escape, then the pressure will build up in the sweet potato and it might explode. That is why poking them ahead of time is so important.

Another option is to peel your sweet potatoes and cut them into cubes. These will cook faster than whole potatoes. Now your sweet potatoes are ready to be boiled. Put them in a large pot, making sure that there is enough water to cover the sweet potatoes completely. You might also want to add some salt or other seasonings to the water to add some extra flavor.

Now bring the water to a boil. You will want to cook the whole potatoes for 30-50 minutes and the cubed potatoes for 15-20 minutes. When they are done, the sweet potatoes should be soft and easy to pierce with a fork. These now can be used in a multitude of fun recipes or just mashed and served with cinnamon sugar and butter.


The second way that you can cook sweet potatoes is by baking them. Similar to boiling, baking is a method often used by beginners. This is because little preparation is needed, and you get to leave all of the work to the oven! In addition, this is a great option if you have many dishes cooking at once and so you do not want to waste all your time dealing with sweet potatoes. By baking them, all you have to do is place them in the oven and wait for them to finish cooking.

It does not get much easier than making baked sweet potatoes. Just like boiled potatoes, when you bake potatoes you will want to wash and stab them. While you are prepping your sweet potatoes, preheat your oven to 425 degrees. Now, wrap your whole sweet potatoes in aluminum foil or place them on a baking sheet. Carefully put them in the hot oven. Bake them for 45-60 minutes, until they are soft. Now they are ready to eat!

An alternative to baking sweet potatoes is to roast them. It is very similar to baking, just at a higher temperature. You will want to wash your sweet potatoes and then cube them into small pieces. You can roast them with or without their skin (it is really up to you).

Toss them in oil with kosher salt and place them on a baking sheet. Bake them at 400 degrees for 25-30 minutes, until they start to get crispy. It is important to remember to flip your sweet potatoes halfway through the roasting time to ensure that they are evenly cooked. Once done, these will be crisp on the outside and soft and delicious on the inside.


The third way that you can cook sweet potatoes is by frying them. This method is a bit more advanced than the other two options, but it sure is delicious! If you feel confident in your abilities around the kitchen, then you will definitely want to give the frying method a chance. Once you have a batch of fried sweet potatoes in front of your guests, all will feel right in the world.

Making fried sweet potatoes is a little more complicated than boiling or baking them. Prep your sweet potatoes by washing and cutting them into 1/4 inch strips. Now, place them in a bowl of ice water for at least 30 minutes. This helps remove some starch from your sweet potatoes. While they are in the ice water, mix together 2/3 cup cornstarch and 2/3 cup water.

Next, drain them from the ice water and dip them in the cornstarch and water mixture. Lay them on a paper towel for a few minutes, then place them in hot oil. Your oil should be around 350 degrees. Cook your fries until they brown. This will usually take about 6-10 minutes depending on their size. Place them on a baking rack or paper towels and sprinkle them with salt or cinnamon sugar and enjoy!

What to Serve With Sweet Potatoes

No matter which way they are prepared, sweet potatoes taste really good when served with cinnamon, sugar, and butter. Whether it is mixed into mashed sweet potatoes or sprinkled over a baked sweet potato, this combo tastes delicious.

A unique way to serve sweet potato fries is with marshmallow sauce. This might sound silly, but it is a popular and tasty topping. Because sweet potatoes are so sweet, these fries will pair very well with this fun dipping sauce.

To make the marshmallow sauce, simply melt equal parts mini marshmallows and heavy cream in a pot. Then season it with cinnamon and serve it while both the fries and sauce are still warm. This might just become your favorite way to eat sweet potatoes!

Another fun way to use sweet potatoes is sweet potato pie. Everything is better when it is a desert after all!

If you are looking for a more savory meal, try serving baked sweet potatoes with roasted brussels sprouts or stir-fried zucchini and yellow squash. Or you can roast the sweet potatoes and season them with salt and pepper. Serve them with chicken for a tasty and filling dinner.
