Flavor, Texture, and Ease

• Silky, creamy texture and a mild, crowd-pleasing flavor.

• Ready to enjoy in just 30 minutes from start to finish.
• Low carb by nature, gluten-free, and easy to make vegan.
• Perfect for families, kids love it, and it freezes beautifully.

Ingredients You’ll Need

• 1 tablespoon olive oil or butter
• 2 large zucchini, about 6 cups, chopped into small pieces
• 1 large onion, chopped
• 3 cloves garlic, minced
• 3 cups vegetable stock, chicken broth or bone broth
• ½ teaspoon salt, or to taste
• ¼ teaspoon black pepper
• ¼ teaspoon dried thyme, optional, or substitute with basil
• 1 cup sour cream or heavy whipping cream, use coconut milk for dairy-free
• Olive oil, sour cream, or chopped parsley, for garnish

How to Make the Soup

1. Wash zucchini, trim the ends, and chop into small, even pieces.
2. Chop the onion and mince the garlic.
3. Heat 1 tablespoon olive oil or butter in a large pot over medium heat.
4. Add the chopped onion and minced garlic and cook, stirring often, about 2 minutes until softened and fragrant (do not brown).
5. Add the chopped zucchini, ½ teaspoon salt, ¼ teaspoon black pepper, and ¼ teaspoon dried thyme; stir and cook 1 minute.
6. Pour in 3 cups broth, bring to a boil, then reduce heat and simmer uncovered about 15 minutes, until the zucchini is very tender and starting to fall apart.
7. Remove the pot from the heat.
8. Puree the soup until smooth using an immersion blender in the pot or carefully transfer in batches to a blender (let cool 5–10 minutes and vent the lid when using a regular blender).

9. Stir in 1 cup heavy cream or sour cream (or coconut milk/cashew cream) until fully combined.

10. Taste and adjust seasoning with additional salt, pepper, or a squeeze of lemon or pinch of nutmeg if desired.

Tips for Silky Smooth Soup

• Pick zucchini of similar size and chop them evenly — small dices cook faster and more evenly.
• Don’t let the onions brown; just sweat them gently over medium heat until soft and translucent for a sweet, mellow base.
• Simmer until the zucchini turns really soft, almost falling apart. This gives you that silky, creamy soup when blended.
• If using a regular blender, cool the soup for 5–10 minutes first and blend in small batches with the lid vented so steam can escape safely.
• An immersion blender is the easiest and safest tool here — blending right in the pot gives the smoothest, creamiest result with no mess.
• Want to tweak the thickness? Stir in a bit more broth to thin it or simmer uncovered to thicken it up. For extra creaminess, blend cooked cauliflower or a little boiled potato right in.
• Add cream or coconut milk after you take the soup off heat, and taste again. Cream can mellow saltiness and acid, so adjust seasoning and a squeeze of lemon if needed.
• A splash of fresh lemon juice or a dash of nutmeg will brighten the finished soup and add a lovely warmth.
• If you’re going dairy-free or vegan, choose full-fat coconut milk or rich cashew cream for that luscious texture. Avoid thin plant milks like unsweetened almond unless you want a lighter finish.
• When freezing leftovers, cool completely, leave space in the container for expansion, and reheat gently on low so the cream or coconut milk doesn’t separate.

Variations and Substitutions

• Try topping with crunchy croutons, roasted chickpeas, or a sprinkle of Parmesan cheese for extra texture and flavor.
• For a dairy-free or vegan bowl, swap the cream for full-fat coconut milk or homemade cashew cream.
• Fresh herbs like basil, dill, or parsley stirred in at the end makes the soup pop.
• If you want it thicker, just simmer without the lid to reduce the liquid or stir in some cooked cauliflower or potato before blending.
• A little lemon juice or nutmeg added right before serving wakes up the flavors beautifully.

• Top with crispy croutons, crunchy roasted chickpeas, or a dusting of Parmesan if you like.
• Swap the cream for coconut milk or cashew cream to make it vegan or dairy-free.
• Fresh herbs such as basil, dill, or parsley add fresh flavor and color.
• If you want a heartier texture, simmer the soup down a bit or blend in cooked cauliflower or potatoes before pureeing.
• A bright squeeze of lemon juice or a pinch of nutmeg at the end will lift the flavors beautifully.

Storage and Make-Ahead

• Keep leftover soup in an airtight container and refrigerate up to 3 days.
• You can freeze it for about 2 months. Thaw overnight in the fridge, then warm gently on the stove to keep it smooth.

Notes

• Carbs per serving: Roughly 7 grams net carbs per serving (recipe serves 4).
• Best zucchini: Any kind works here — dark green, light green, or striped. No peeling needed, just wash, trim, and chop.
• Thickening tricks: If the soup feels too thin, simmer uncovered a few minutes to reduce. You can also blend in cooked zucchini, potato, or cauliflower, or stir in a cornstarch slurry.
• If flavors seem flat: Boost with extra herbs like basil, parsley, dill, or thyme. A splash of lemon juice or pinch of nutmeg will brighten things up. Parmesan cheese adds a nice depth if you’re not vegan.
• Dairy-free option: Swap heavy cream for coconut milk, almond milk, or cashew cream. Blending in cooked cauliflower also smooths it out naturally.
• Serving ideas: Pair with crusty bread, crackers, or fresh salad. Top with croutons, roasted chickpeas, Parmesan, or chili flakes for a bit of kick.
• Storage: Keep in a sealed container in the fridge up to 3 days or freeze for 2 months. Reheat gently to avoid breaking the creaminess.
