Winter squashes are my favorite vegetables to cook with during the cold weather months. They’re so hearty and sweet, and especially well-suited to making delicious, comforting soups!
Cooking these hard squashes is a snap in a pressure cooker like the Instant Pot. You can have a steaming, creamy bowl of butternut squash soup on the table in about 45 minutes!
3 Easy Steps to Butternut Squash Soup
This soup is made in three easy steps:
- The butternut squash is cut into quarters and steamed in the pressure cooker. (I love my Instant Pot!) Once steamed, it’s very easy to scoop the flesh away from the tough outer skin. This is a great way to prepare winter squash if you’re wary of peeling and dicing hard, raw squash.
- Next, you’ll sauté the other veggies for the soup right in the Instant Pot. This is a basic mix of celery, carrots, and onions along with the second star ingredient of this soup, a sweet-tart Granny Smith apple. The apple adds an extra dimension of flavor, and lightens up the texture of the soup, too.
- Finally, add the squash back to the pressure cooker and use an immersion blender to pureé it into soup. You can use a regular blender if you want, but I love this easier, less messy option.

How to Make Thicker Soup
Love really thick butternut squash soup?! Add just half of the recommended amount of broth, puree, and then stir in additional broth as needed until you reach the consistency you prefer.
If you’ve already added the stock and think your soup is too thin, try adding a few pieces of bread or a cup of canned white beans and pureeing the soup again. This will thicken the soup right up!
What to Serve with Butternut Squash Soup
Serve the soup with a dollop of plain yogurt and a sprinkle of chives on top.
How to Freeze Butternut Squash Soup
This soup will keep in the fridge for about a week and can be reheated in the microwave or over low heat on the stovetop.
To freeze, transfer to freezer containers or bags, then freeze for up to three months. Thaw overnight in the fridge if you have time, or warm the frozen soup over low heat on the stovetop until steaming.

Pressure Cooker Butternut Squash Soup Recipe
- 1 medium (2 1/2 to 3 pound) butternut squash
- 1 1/2 cups water
- 2 tablespoons unsalted butter
- 1 medium yellow onion, chopped small
- 1 celery rib, chopped small
- 1 medium carrot, chopped small
- 1 large (8-ounce) Granny Smith or other tart apple, peeled, cored, and diced small
- 1 quart chicken or vegetable stock
- 1 pinch each of nutmeg, cinnamon, cayenne, salt and pepper
- Chopped chives
- Plain yogurt
- 6-quart Instant Pot or other pressure cooker
1 Prepare the squash for steaming: Lay the squash on its side on a cutting board — you can hold onto it with a kitchen towel for extra stability. Slice off the stem, then cut the squash in half through the middle, where the thinner neck meets the larger bottom. Cut each section in half again, then scoop out the seeds.
2 Pressure-steam the squash: Place a wire metal trivet in your electric pressure cooker (6-quart or larger) and pour in 1 1/2 cups of water. Arrange the pieces of squash on top of the trivet in a single layer. It’s fine if they overlap a bit.
Secure the lid on your pressure cooker, and make sure the pressure release valve is set to its sealing position. Select the “Steam” or “Manual” setting, and set the cooking time to 7 minutes at high pressure. (If you’re using a stovetop pressure cooker, steam the squash at high pressure for 6 minutes.)
The pot will take about 10 minutes to come up to pressure, and then the cooking program will begin.
When it’s finished cooking, move the pressure release valve to its venting position. When the pressure has fully released, open the pot and use a pair of tongs to transfer the squash to a cutting board to cool.
3 Sauté the other ingredients and add the broth: Remove the inner pot from the pressure cooker housing, remove the trivet, and pour out the water. Return the inner pot to your pressure cooker.
Reset the cooking program on your pressure cooker, and select the highest “Sauté” setting. Melt the butter in the pot.
When the butter is melted and bubbling, add the onion, celery, carrot, and apple. Sauté until the onions are translucent, about five minutes.
Pour in the broth and let it come to a simmer.
4 Scoop the squash from the skin and add it back to the pot: While you're waiting for the broth to come up to a simmer, use a big spoon to scoop the squash from the outer skin. Add the squash to the pot (it's ok if the broth isn't simmering quite yet).
5 Simmer the soup: Let the soup simmer until the apples and other vegetables are soft, 5 to 7 minutes or so.
6 Puree the soup, season, and serve: Use an immersion blender or a traditional blender to process the soup until it is smooth. (If using a traditional blender, puree in batches with the top slightly loosened. Use a dishtowel to hold down the lid while blending.)
Stir in the spices and taste, adding more salt if needed. Ladle the soup into bowls and serve it with a dollop of yogurt and chives sprinkled on top.
This soup will keep for about a week in the fridge, or frozen for up to 3 months.
