What is buttercup squash?

Before you start thinking I misspelled butternut squash, let me reassure you: this is buttercup squash, like the princess in the Princess Bride.

If you haven’t ever tried this squash, you aren’t alone. It’s not very well known, but it is so delicious that I think you should try to find one and cook it.

Butternut squash is tan, but buttercup squash has dark green skin. It has a relatively flat shape, and you might see a few streaks of light green color on the exterior. It has a bright orange flesh when you cut it in half – the contrast of color is very eye-catching.

What does buttercup squash taste like?

It’s tough to describe the flavor of buttercup squash – just know that it tastes nothing like any other squash you might have eaten before. It has a very sweet flavor that most closely resembles a kabocha squash.

Buttercup squash has a smooth texture – not stringy like spaghetti squash. After you cook it, you’ll notice the predominantly sweet flavors – they even linger on your tongue a bit after you are done eating it.

Different ways to cook buttercup squash

There are several different methods for cooking it, but our favorite way is to cook buttercup squash in the oven. Here are a few other ways to cook this winter squash:


Cutting the buttercup squash into cubes and placing them in a steamer basket is a perfect way to cook them. This way, you can easily get a smooth puree or mash out of them.

Steaming the squash is also a fantastic idea if you want something that is really easy to clean up.


Cut the buttercup squash into cubes, and place in boiling water. Boil until they are tender enough to easily pork with a fork. Boiling buttercup squash is ideal when you want to make a puree. You can also sauté the boiled squash if you want to make it a little crispy on the outside.

Air frying

Do you like squash that is crispy on the outside and soft on the inside? If so, then the air fryer might be a good choice for you! It gives you the same result as a deep-fryer, but it’s so much better for you because you use air to fry it instead of oil.

Air frying is super-simple and is really easy to clean up as well.

Here is everything you need to know about roasted buttercup squash in the oven.

Slice it

The first step is to cut the squash into slices. Start by removing the top and bottom of the buttercup squash. Then, cut it in half and remove the seeds. Next, cut it into slices that are ¼-inch thick.

Season it

After you slice the squash, season the slices. I have a recipe in a printable recipe card at the bottom of this post. In my recipe, I used paprika, cumin powder, salt, and black pepper.

So, place the slices of squash on a parchment-lined baking tray and then drizzle the slices with olive oil and sprinkle the spices on top.

Roast it

Now you’re ready to roast your buttercup squash. To do this, put the baking tray full of squash in a preheated oven at 425-degree F for about 40 minutes.

About halfway into the cooking, remove the baking tray from the oven and flip the slices over, so they roast evenly on both sides. Drizzle them with more olive oil and seasonings and place the baking tray back in the oven for 20 more minutes. Once they are done, serve.

Buttercup squash variations

You can add all kinds of seasonings and spices to create different flavors. Here are a few spices and ingredients you can try out on your buttercup squash.


Cinnamon has a sweet, woody, and warm flavor. Sprinkle it on buttercup squash to make a unique side dish.


Nutmeg brings a powerful aroma to any dish. You can sprinkle it on the buttercup squash to elevate the flavor.


Pumpkin pie spice

Who says pumpkin pie spice is just for pumpkin? Try it over squash – I am sure you will love it.

Maple syrup

Believe it or not, maple syrup goes very well with buttercup squash. It, along with salt and black pepper, acts as a glaze and creates an interesting flavor.

Jerk seasoning

You can spice things up by adding jerk seasoning. Be careful, though – a little bit goes a long way!

How to store leftover buttercup squash

Once it is completely cool, place it in an air-tight container and store it in the refrigerator. It will stay good for up to 5 days. You can reheat it in the oven for about 3 to 5 minutes.
