Ingredients

The ingredient list for the Instant Pot sweet potatoes and butternut squash is a simple list. We kept it to only 5 ingredients, but you can always add other spices if you choose.

Sweet Potatoes - You are cutting them up so it's not a problem if they are all different sizes. It's often hard to get them all the same size, so don't worry about that!

Butternut squash - You do not need a huge butternut squash, you will not be using the whole squash. The remaining squash can be cooked and frozen or kept in the fridge for up to 4 days for another meal.

Butter - I love salted butter here to give it a little bit of salt, but you can substitute the butter. It is used for flavor.

Nutmeg - If you do not have plain nutmeg, you can substitute the cinnamon and nutmeg with pumpkin pie spice. Use between 1 half and 3 quarters teaspoon pumpkin pie spice. Doesn't have to be exact. You can leave the nutmeg out if you prefer to use just cinnamon.

Cinnamon - See nutmeg, can substitute with pumpkin pie spice.

Salt and pepper - Optional and add to taste. We add it at the table here.

Making Instant Pot sweet potatoes and butternut squash

The Instant Pot makes this side dish so much easier just like our Instant Pot mashed potatoes because it is so much easier then boiling them.

Prepping

Peel and cut up your sweet potatoes and squash. Butternut squash can usually be purchased whole or even cut in half and peeled for you at the supermarket. Some supermarkets sell it cut in half already.

They should be cut to close to the same size, large bite sized pieces - about 1 and a half to 2 inches. They both cook pretty quick when they are cut to this size.

Cooking

Place the sweet potato and the butternut squash chunks into the inner pot. We mix them up and put them in, they don't have to be layered separately.

Pour the water over the veggies and then add the cinnamon and nutmeg. Butter goes on top in thin slices to evenly place it around.

Place the lid on and put the vent into the sealing position. Cook on high pressure for 3 minutes and carefully do a manual release.

Once the pressure is released, remove the lid and stir gently. The squash will be a little softer so be careful stirring. Remove and put into a serving bowl - enjoy!

Making mashed sweet potatoes and butternut squash

This is one of the most flexible sweet potato and butternut squash recipes. You can even make these mashed sweet potatoes and butternut squash, but you might need to drain them or mash them in a mixing bowl. The squash has a bit of moisture and creates more liquid then you would want when mashing them.

I have tried to reduce the amount of water, but you are likely to get a burn warning with less water. It is best to mash in a separate bowl if mashing!

You also want to increase the cook time to 4 minutes to be sure that everything is soft enough to mash easily.

Remove from the inner pot and place into a mixing bowl. You can add more butter if you like (we do but it's optional) and use either 1-2 tablespoons of milk or 1-2 tablespoons of the water left in the inner pot to mash them.

A potato masher works great or you can use a mixer to get it perfectly smooth.

• 6 quart or 8 quart Instant Pot - We use these two sizes quite often. You would need to reduce the amount made if using a 3 quart.
• Mixing bowls - This is perfect for if you are mashing the potatoes and squash.
• Slotted serving spoon - This makes it easier to remove the potatoes and squash from the inner pot after cooking. There will be a bit of liquid on the bottom from the cooked squash.
