Yes, surprisingly, kids love it!

What should I put in my vegan zucchini soup?

Zucchini – You can use any size zucchini you like as long as you have about 4 cups in total. If you have large ones with big seeds, cut the seedy parts out. (You can also use yellow squash in equal parts or half zucchini and half yellow squash if you would like to).

Potatoes – This thickens the soup and makes it creamy. About 4 medium potatoes usually work well. You can add a little more or less to control the consistency.

Tomatoes – This can be any type of tomatoes. I usually use about 2 medium-sized tomatoes or about 1 cup of cherry tomatoes.

Bell Peppers – Red, orange or yellow bell peppers are the sweetest and give this soup the nice flavor.

Water – Use enough water to cover the vegetables in the pot. The exact amount will vary depending on how many veggies you put in it.

Salt – For flavor. I usually need about 2 tsp for a pot, but adjust to your taste.

Basil or Pesto – I love pesto in this soup, but if you don’t have it fresh basil also gives it a wonderful flavor too. You can use my I love pesto in this soup, but if you don’t have it fresh basil also gives it a wonderful flavor too. You can use my vegan pesto recipe to easily make your own.

How do I make creamy vegan zucchini soup?

You can choose between 3 methods of making this soup. Use a pressure cooker, a crockpot, or simply boil the ingredients in a pot on the stovetop.

Throw all of the veggies into the pot with enough water to just barely cover them. Let it build up to pressure and then turn it off. Come back when the pressure releases and salt and vegan pesto (or basil) and puree with an immersion blender until creamy.

Crock-pot method:

Put everything in the pot in the morning. (Add an additional 1 cup water). Turn it on low for 8 hours or high for 5-6 hours. Then add salt and vegan pesto (or basil) and puree with an immersion blender until creamy.

Stovetop method:

Throw all of the veggies into a soup pot with enough water to just barely cover them. Boil until the veggies are very soft (about 25 minutes). Then add salt, basil, or vegan pesto, and puree with an immersion blender until creamy.

Any way that you make it, it always comes out creamy and delicious!

Pro tips for delicious zucchini soup:

I like to use a metal immersion blender for this soup. This way I don’t have to transfer it to a blender and I’m not touching plastic to such hot liquid.

If you don’t have an immersion blender, you can transfer small amounts to your blender to puree it, but be careful not to overfill the blender or hot liquid could leak out and burn you.

Pesto makes this soup delicious! It is hard to find dairy-free pesto in the stores, but super easy to make your own vegan pesto recipe

Add slightly more water for a thinner soup, add less water, or an extra potato for a thicker soup.

If you are using a very large zucchini, be sure to cut out the section with large seeds.
