There is more than one right way to make mashed sweet potatoes. Some people boil their potatoes, while other people bake them.

In this recipe, I have chosen to bake my sweet potatoes. It’s fast, easy, and the result is always fantastic. Plus, you have the option to puree with the skin or without.

Basically, it leaves you with options and options are my favorite.

As for the butternut squash? I steamed the butternut squash. Why? It’s easy. Plus, healthy. Roasting is a delicious alternative but it would require additional olive oil (if you prefer to roast your butternut squash follow this guide).

How to Bake Sweet Potatoes

There are quite a few methods out there on what is considered the “best” way to bake a sweet potato. This is my method.

Preheat oven. Preheat oven to 425 degrees F and line a large baking sheet with parchment paper. Spray lightly with nonstick cooking spray.
Prepare the sweet potatoes. Wash and scrub each sweet potato and dry thoroughly. Transfer to the baking sheet and, using a knife or a fork, stab each sweet potato at least 6-7 times (this will vary depending on the size of your potato).
Bake. Transfer potatoes to the oven and bake for approximately 30 minutes. Rotate the pan 180 degrees to ensure even cooking and bake for an additional 15-30 minutes, or until you see some of the natural sugars have started to caramelize and a fork or knife is easily inserted into the thickest part of the potato.
Serve. Remove from the oven and allow potatoes to rest for 5 minutes before seasoning with salt, pepper, butter, or maple syrup if desired.

Can you boil the sweet potatoes?

Yes! In fact, I’m going to guess that this is probably how many people prepare their mashed sweet potatoes.

How long do you boil sweet potatoes?

Sweet potatoes need approximately 15-20 minutes to boil. Time will vary depending on how large or how small the sweet potatoes were chopped. To test if the potatoes are ready, use a slotted spoon to remove one piece from the pot. Pierce with a fork. If it easily slides in and out, the potatoes are fully cooked and ready to mash.

This method is faster than baking whole sweet potatoes and perfect whenever you want mashed sweet potatoes in a hurry. However, baked sweet potatoes taste better.

How to make Mashed Sweet Potatoes

Prepare the vegetables. Prepare the sweet potatoes. Wash and scrub each sweet potato and dry thoroughly. Use a knife or a fork, stab each sweet potato at least 6-7 times (this will vary depending on the size of your potato). Meanwhile, peel, seed, and chop your butternut squash into large cubes for steaming. If you prefer not to use butternut squash, simply double the number of sweet potatoes and omit the butternut squash.
Preheat and boil. Preheat oven to 425 degrees F and line a large baking sheet with parchment paper. Transfer the sweet potatoes to the parchment-lined baking sheet. Meanwhile, add a steamer basket to a medium pot filled with approximately 1-2 inches of water. Transfer the chopped butternut squash to the steamer basket, cover, and bring to a boil.
Bake and Steam. Transfer potatoes to the oven and bake for approximately 30 minutes. Rotate the pan 180 degrees to ensure even cooking and bake for an additional 15-30 minutes, or until you see some of the natural sugars have started to caramelize and a fork or knife is easily inserted into the thickest part of the potato. Meanwhile, steam the butternut squash for approximately 15-20 minutes, or until fork tender.
Puree. Once the butternut squash has finished steaming, transfer to a large blender. Remove the sweet potato from the oven and allow to rest for 5 minutes before handling. Slice the potatoes in half and carefully peel the skin away from the soft inside. Transfer the inside of sweet potato to the blender with the cooked butternut squash.* Add the milk and puree until smooth and creamy.
Season and serve. Transfer the creamy mashed sweet potatoes to a large mixing bowl. Melt in the butter and stir in maple syrup to taste. Season with salt, to taste, and garnish with fresh thyme, if desired.

Can Mashed Sweet Potatoes be Made Ahead of Time?

Yes, absolutely. To make Mashed Sweet Potatoes ahead of time follow steps 1 through 4 (wash, bake, boil, peel, mash, puree) however, wait to add the butter and maple syrup. Transfer the prepared mashed sweet potatoes in a large microwave-safe container (glass is best) and store in the refrigerator for up to two days. When ready to prepare, reheat until warm in the microwave, adding butter and maple syrup, to taste.

What is the best way to make Mashed Sweet Potatoes creamy?

There are several ways to make sweet potatoes smooth and creamy- by using a potato masher, electric hand blender, or, a blender. I tried every single one of these methods on this recipe and only one method provided the super creamy mash/puree that I was looking for.

The winner? Blend your potatoes in a blender.

Now, if I hadn’t added butternut squash, the electric hand blender would have worked just as fine. But, butternut squash is stringier and requires a bit more blending.

My other bit of advice for super creamy mashed potatoes?

Thoroughly drain the water. If you boil your potatoes (or butternut squash) remove as much water as possible. Water will not make fluffy mashed sweet potatoes.
Add some milk or cream. You don’t need a lot, but a splash or two adds great flavor and creaminess.

How to reheat Mashed Sweet Potatoes?

The microwave. I recommend reheating in a glass container covered (not sealed) with a lid. Heat at 30-second intervals, stirring after each.

Some people say that you can place the mashed sweet potatoes in a ziplock bag and submerge in a pot of boiling water, but I do not recommend this. It is never a good idea to reheat food in plastic.

Can you mash sweet potatoes with the skin on?

Yes, definitely!

This is entirely based on personal preference. The skin of sweet potatoes is delicious and healthy and packed full of vitamins and minerals.
