How To Make Instant Pot Mushroom Sweet Potato Soup

This soup is a true dump and go recipe, that requires very little prep time.

Chop the onions, mushrooms and sweet potato with a sharp knife and add them to your Instant Pot with the salt, pepper and water. Cook on high pressure and quick release. Stir in the peas and heavy cream and it’s ready to serve.

It’s so effortless to make this soup!

The ingredients in the instant pot

Can you blend this sweet potato soup?

I prefer not to blend my soups, I enjoy chunky soups with whole pieces of veggies. If you prefer a smooth soup though, you can use an immersion blender to puree it. Alternatively, you can ladle the soup into a stand blender in batches, just be careful though as it will be piping hot!

The soup before adding the cream

Can you make the soup ahead of time?

This soup is such a great make ahead dish, and it’s perfect for meal prep lunches and dinners. Once you have made the soup, let it cool completely and transfer it to an air tight container. It will keep in the fridge for up to 5 days.

You can also freeze the soup and it will keep for up to 3 months (click here for freezer soup containers I recommend). Thaw the frozen soup in the fridge overnight before reheating it on the stovetop or in the microwave to serve.

You can also reheat the soup in the Instant Pot.

The finished soup in the Instant Pot ready to serve

Can you use frozen peas in this Instant Pot soup?

If you don’t have canned, you can use frozen or fresh peas. The canned peas are already cooked, so they can be added straight to the soup and served up straight away. If you use frozen peas, thaw them under running water before adding to the pot and allow them to sit in the soup for a few minutes before serving so that they cook through.

Fresh peas can be added straight to the soup, again, just let them cook through for a few minutes.

The soup on a ladle

Can you make this soup on the stovetop?

If you don’t have an Instant Pot, you can make this delicious soup on the stovetop. Make the soup in a dutch oven or heavy bottomed pot.

Add the ingredients as per the recipe instructions and bring to a boil. Let the soup simmer for 30 to 40 minutes until the sweet potato is softened. Stir in the cream and peas and serve.

Can I use a stock for the base of this sweet potato soup?

I made this soup with water, but if you have some stock, you can use that instead of water for more flavor. You can use a vegetable or chicken stock, both work well (check out my Instant Pot chicken stock recipe). If you use a stock with salt, rather than adding the salt and pepper before cooking, you may want to wait until the end. Taste the soup and add it if you need it.

Easting the mushroom sweet potato soup with a spoon

Make this mushroom and sweet potato soup your own!

I love this soup just as it is, but you can easily add in any other veggies you have in your fridge. Carrots work really well as do leeks and green beans.

If you like your soup on the spicy side, try adding in some red pepper flakes, or add in a tablespoon of dried herbs.
