Bisque ingredients

The ingredients for Hubbard squash bisque are common items found in most kitchens. I’ve kept the ingredients for this squash bisque soup fairly simple and straightforward to allow the squash flavor to shine.

If you’ve had butternut squash bisque, it will taste very similar. Hubbard is a bit earthier in flavor than butternut, so it will really taste of squash, in the best possible way.

How to make squash bisque

Making bisque is a snap, really. It’s one of those dishes that most people only order at a restaurant because the assumption is that it is difficult to make. I’m here to tell you that is completely false. It seriously could not be easier.

The first step is to cook Hubbard squash for the soup. The easiest way is to split it in half, remove the seeds and roast in a hot oven. Roasting the squash is not only the easiest method, it also delivers the best flavor.


The edges of the Hubbard squash will caramelize in the oven, giving your bisque an amazing flavor. Then sauté some onions and garlic in olive oil or butter until they are softened.

Add the roasted Hubbard squash, sautéed onions and garlic, and roasted carrot to a blender.

The blender I own is a Vitamix. It isn’t inexpensive, but it is the industry standard in professional kitchens. It can handle anything you throw at it and this blender lasts forever. It also allows you to manually control the speed of the blades – that’s a game-changer.

Pour in the chicken stock and blend it all up until it is completely smooth. In a standard blender, this will take a few minutes. A powerful immersion blender will work (the one I own and recommend is the Breville BSB510XL), but it will be difficult to get it as velvety smooth as a regular blender with a pitcher.

After a few minutes in the blender, this is what your Hubbard squash bisque will look like – completely smooth, thick and absolutely gorgeous.

Squash bisque FAQ’s

Can I freeze this Hubbard squash bisque?

Yes! It freezes beautifully. You’ll want to freeze it BEFORE you add the cream, though. Dairy tends to get grainy after it has been frozen, so I’d leave that out until you’re ready to reheat and eat.

How can I make this squash soup vegan?

Swap full fat coconut milk for the heavy cream and voila – it’s vegan. You could also use any type of non-dairy milk that you like, but it will not be quite as thick.

What’s the difference between bisque and soup?

A bisque is traditionally made with cream and it is smooth and generally fairly thick. A soup can be anything from a brothy affair – like a chicken noodle to something thicker like a potato soup.

How to swirl cream on soup

If you’ve ever tried to make pretty swirls on top of soup with cream only to have it feather and run all over the place – keep reading.

There are a few tricks to this and I’m going to tell you EXACTLY how we do this in restaurants, so you can replicate it at home.

First, you need heavy cream that is very cold. I usually put mine in the freezer for about 15 minutes to get it super cold.

Next, you’ll need a squeeze bottle. They come in handy for so many things, not just swirling cream on a bowl of soup!

Pour the ice cold cream into the bottle, screw the top on and cover it with your finger while you shake vigorously for about 20 – 30 seconds. Don’t be gentle with it – you need to incorporate air into the cream – this is what helps it float on top.

You can whip it with a whisk, but this is faster and less hassle. After the cream has increased in volume, add circles of cream on top of the soup.

Finally, use a thin skewer or a toothpick to swirl the edges of the cream into a pretty pattern. That’s it. Once you know the trick to it, it’s super simple.
