Pro Tips

• for Perfect Zucchini Soup
• For the smoothest texture, use an immersion (stick) blender directly in the Instant Pot. It saves on cleanup and is much safer than transferring hot liquid.
• Don’t peel the zucchini! The skin contains nutrients and adds a beautiful, vibrant green color to the finished soup.
• For a dairy-free version, substitute the butter with olive oil and the heavy cream with one can of full-fat coconut milk.
• Elevate the flavor by garnishing with fresh herbs like dill or basil, a dollop of sour cream, or some toasted pumpkin seeds for crunch.

FAQ

Q: Should I peel the zucchini for this soup
A: No, do not peel the zucchini. The skin contains nutrients and is key to achieving the soup’s beautiful, vibrant green color. Just wash the zucchini well before chopping.

Q: Can I make this zucchini soup dairy-free
A: Yes, you can easily make a dairy-free version. Substitute the butter with olive oil and replace the 2 cups of heavy cream with one can of full-fat coconut milk for a similar creamy result.

Q: What if I don’t have an Instant Pot
A: While this recipe is designed for an Instant Pot, you can make it on the stovetop. Sauté the onion and garlic in a large pot, add the zucchini, stock, and seasonings. Bring to a boil, then simmer for about 10-15 minutes until the zucchini is very tender before blending and adding the cream.

Q: How do I get the smoothest texture
A: For the smoothest, most velvety texture, use an immersion (stick) blender directly in the pot after pressure cooking. This method is safer than transferring hot liquid to a traditional blender and results in less cleanup.
