Spoonful of buttercup squash soup held over the  soup pot

Whenever I see new and unique ingredients at the farmers’ market, I always have to try them. That’s how I came across this buttercup squash, a type of winter squash I’d never heard of before.

One night, I decided to try making a buttercup squash soup. I assumed it would be yummy, satisfy my hunger, and at least give me a chance to try the squash. I didn’t expect that I would absolutely LOVE this soup!

If you can’t find buttercup squash, you can easily substitute it for butternut or any other winter squash variety. However, if you are able to find butternut, I highly recommend it. It’s such a treat!

This cozy soup is also a great source of vitamins, minerals, and antioxidants, so you can feel good about enjoying a bowl!

How to make buttercup squash soup

This soup recipe is fairly simple to make. In fact, the hardest part is just peeling the squash!

Squash, onion, butter, and stock on a table

Step 1: Peel and seed the squash, then cut it into 1-inch square chunks and set aside.

Step 2: Add the butter to a large pot. Once the butter is melted, add the chopped onion and cook until translucent, about 5 minutes.

Step 3: Add the squash and stir, then add 5 cups of stock.

Step 4: Turn up the heat and bring everything to a low boil, then reduce the heat to low and simmer until the squash is tender. If the pan gets too dry while cooking, add another cup of stock.

Step 5: Either transfer the soup to a food processor or use a stick blender right in the pan to purée the soup. Once smooth, season to taste with salt, pepper, and nutmeg.

Buttercup squash vs. butternut squash

So what exactly is buttercup squash?

On the outside, it looks completely different than butternut squash. But once you slice them open, they have a very similar creamy orange flesh.

Buttercup has a sweet and nutty flavor, although it’s a little less sweet than butternut. It’s also known as a drier squash, which makes it great for steaming, baking, or using in a soup.

The two squash types can easily be substituted for one another, so if you can’t find buttercup, don’t fret! Butternut will be just as delicious in this recipe.
