Carrot and Acorn Squash Soup with Carrot Top Pistou

Carrot and Acorn Squash Soup with Carrot Top Pistou

Carrot and Acorn squash soup with carrot top pistou is a delicious soup and this version used the carrot tops to make the most delicious pistou! This pistou is a carrot green pesto and so delicious. This makes a great soup for Fall and Thanksgiving. During this time of year, soups and all types of squash are on the menu.

The difference between homemade butternut squash soup and homemade acorn squash and carrot soup:

I am not a big fan of sweet squash so I decided to try a soup made with acorn squash which is only mildly sweet. Most people use butternut squash for their squash soup but I love mixing the mild acorn squash with carrot for the best flavor. The carrot adds a nice depth of flavor that I feel is lacking in a full butternut squash soup.

The carrot addition to this Carrot and Acorn squash soup was inspired by a recent visit to a conference at the Fairmont Hotel here in Austin, Tx.

The chef made a carrot soup with a carrot top pistou which was amazing and I loved that the tops were used and not discarded! It definitely needed to be re-created at home!

What is the carrot top pistou?

If you are not familiar with pistou, it is sort of like a French pesto. It comes from the Provence region and is usually made with basil. garlic and olive oil and it’s used to top soups.

This recipe forgoes the basil and uses the green tops of the carrots instead. It is essentially a carrot green pesto. It is amazing! Below I list my favorite things about what makes this soup special for me. I hope you give it a try!

This soup goes so well as a main dish or as a side for Thanksgiving! If you are here looking for more sides to go on your Thanksgiving table, I’ve included some Thanksgiving recipe links below from fellow bloggers that will definitely help you out!

Here are the steps to making this soup:

Step 1 – First you are going to add all of your veggies to a large sheet pan and roast them in the oven. Just a little olive oil is all you need to add to them before roasting.

Step 2- Now you add the fully roasted vegetables into a large pot and mash them down a little. You don’t have to mash too much since they will be going into the blender later.

Step 3 – Add your stock and mix that into your mashed veggies. Once you mix it all around you will now start to bring it over to your blender to puree all of the soup. This can be done in batches.

Step 4 – Add the pureed soup back into your large pot on the stove and add your heavy cream. After you mix in the heavy cream well it will get thick and silky.

Step 5 – Once the cream is well incorporated and you bring the soup back up to a good hot temperature, taste for seasoning. This is when you add any salt or pepper that it may need (to taste).

That is it. It is very easy. To serve the squash and carrot soup, just ladel some soup into a bowl and top with a dollop of your pistou. The pistou is so good!

Highlights of this squash and carrot soup:

  • The carrots and squash are roasted until caramelized adding a great lightly sweet and nutty flavor
  • There is little food waste since we are using the carrot tops to make the pistou
  • The garlic and Parmesan from the pistou compliments the sweetness of the soup adding depth of flavor

This is so easy to make and not a boring fall squash soup at all!

Carrot and Acorn Squash Soup with Carrot Top Pistou

A delicious and creamy Fall soup with an amazing carrot top pistou
Prep Time10 mins
Cook Time30 mins
Total Time40 mins
Course: Soup
Cuisine: American
Keyword: soup
Servings: 6 people


  • High powered blender for pureeing the soup


  • 2 acorn squash cleaned, cut in half and seeds removed
  • 8 medium fresh carrots with green tops cleaned and peeled and green tops reserved
  • 32 ounces chicken stock good quality
  • 2 cloves of garlic minced
  • 1 cup heavy whipping cream
  • 1 bay leaf
  • 1/2 tsp dried thyme
  • 1 shallot diced
  • 1/8 cup good quality olive oil (half for soup and the other half for your pistou) plus a little more for drizzling on vegetables
  • 1 tbsp salt and pepper or to taste

Carrot Top Pistou (carrot top pesto)

  • 1/4 cup grated Parmesan cheese
  • 1/8 cup extra virgin olive oil
  • 1 whole bunch of carrot top greens rinsed and coarse chopped
  • 1 clove of garlic course chopped


  • Pre-heat your oven to 400 degrees
  • Add your cut and cleaned carrots (not the green tops) and cut and halved acorn squash to a sheet pan and drizzle with olive oil and sprinkle with salt and pepper.
  • Roast your vegetables for about 20-25 minutes or until they start to brown a little and are soft all the way though
  • Once cooked, remove from the oven and let cool for a minute before handling
  • In the meantime, heat a large heavy bottom pot over medium heat and add 1/2 of your olive oil
  • Now add your diced shallots and 1 clove of your minced garlic and cook for about 4-5 minutes
  • Now add your chicken stock, thyme and bay leaf
  • Now we are going to get the roasted vegetables ready to add to the pot by scooping the flesh of the acorn squash away from the skin. You may be able to just peel the skin of the squash right off.
  • Once this is done, you can add your whole carrots and the flesh of the squash right into your soup.
  • You can mash it down a bit with the back of your spoon. Don't worry about smoothness here since we will be pureeing it all in a blender.
  • Now add your salt, pepper and your cream
  • Mix it well and let it come to a light simmer
  • Once it has simmered for a few minutes, remove your bay leaf and discard.
  • Bring your pot over to the blender (If you have an immersion blender, you can just puree your soup right in the pot and skip the blender steps)
  • Add your soup to the blender making sure to only fill it 3/4 of the way to the top as hot soup will expand in the blender
  • Place the top on your blender tightly and cover with a towel. Puree your soup on high for 2 minutes or until smooth
  • You may need to do this in batches to make sure you do not over fill your blender
  • Once your soup is all blended and smooth, add it back to your pot. Taste for any seasoning (add salt and pepper to taste) then place over low heat with a lid on top.

Carrot top pistou (carrot top pesto)

  • Take the green tops from your carrots and finely chop them
  • Add this to a food processor along with the remaining 1/8 cup of olive oil, 1 clove of minced garlic and your Parmesan cheese and blitz until it is smooth.
  • Add your pistou to a small bowl


  • Ladle your soup into bowls and top with a dollop of the pistou
  • Enjoy!


For making a more traditional Italian pesto with the carrot top greens:
You can add 1/2 cup of nuts (almonds or walnuts) and 2 more tablespoons of olive oil to the pesto recipe and mix in the food processor until somewhat smooth.
