Freezer-friendly – Yes, it freezes beautifully.
Ingredients
For the soup:
-
3 medium zucchinis (about 1.5 lbs / 680g), roughly chopped
-
1 medium yellow onion, diced
-
2 cloves garlic, smashed
-
1 small russet potato (about 4 oz / 110g), peeled and diced
-
1/4 cup raw cashews (see notes for nut-free)
-
3 cups vegetable broth (low sodium preferred)
-
1 tablespoon olive oil or avocado oil
-
1/2 teaspoon salt (plus more to taste)
-
1/4 teaspoon white pepper (or black pepper)
-
1/4 teaspoon ground nutmeg (optional but transformative)
For garnish (optional):
-
Toasted pumpkin seeds
-
Fresh chives or basil
-
A drizzle of extra-virgin olive oil
-
Cracked black pepper
Instructions
Phase 1: Sauté (Intensity: Low)
Time: 5 minutes
-
Heat olive oil in a large pot or Dutch oven over medium heat.
-
Add diced onion and a pinch of salt. Cook until translucent (about 3 minutes), stirring occasionally.
-
Add smashed garlic and cook for 1 minute until fragrant. Do not brown the garlic — bitterness is the enemy of creaminess.
Phase 2: Build the Base (Intensity: Low)
Time: 2 minutes
-
Add the chopped zucchini, diced potato, and raw cashews to the pot. Stir to coat in the aromatics.
-
Sprinkle in the salt, white pepper, and nutmeg.
Phase 3: Simmer (Intensity: Low)
Time: 15 minutes
-
Pour in the vegetable broth. Increase heat to high and bring to a boil.
-
Once boiling, reduce heat to medium-low, cover, and simmer for 15 minutes.
Test: Potato should be fork-tender; zucchini should be very soft.
Phase 4: Blend (Intensity: Medium — Hot liquid caution)
Time: 3–5 minutes
-
Remove pot from heat. Let cool for 2 minutes (safety first).
-
Option A (High-intensity blending): Use an immersion blender directly in the pot. Blend on low, then high, until completely smooth (about 2 minutes).
-
Option B (Standard blender): Working in batches, carefully transfer soup to a countertop blender. Fill only halfway, hold the lid with a towel, and blend starting on low speed. Vent the lid to allow steam to escape.
-
Blend until the soup is silky and no graininess remains. *For ultra-creamy texture, blend for a full 60 seconds after smooth.*
Phase 5: Adjust & Serve (Intensity: Low)
-
Return soup to pot (if using countertop blender). Taste and adjust seasoning — more salt? A squeeze of lemon for brightness?
-
If too thick, thin with 1/4 cup water or broth. If too thin, simmer uncovered for 5 more minutes.
-
Serve hot with your choice of garnishes.

Pro Tips for Maximum Creaminess
-
Don’t skip the potato — It adds starch that emulsifies the soup naturally. A sweet potato works too (but changes color/flavor).
-
Soak cashews if you have time (30 minutes in hot water) for an even smoother result. Not required, but next-level.
-
Blend hot, not cold — Blending while still hot creates a lighter, airier emulsion.
-
Pass through a sieve for restaurant-quality texture (adds 5 minutes, removes any stray zucchini seeds).
Variations & Substitutions
-
Nut-free: Replace cashews with 2 tablespoons of raw sunflower seeds or 1/4 cup cooked white beans (adds protein too).
-
Vegan: Already vegan as written.
-
Higher protein: Add 1/2 cup canned white beans during blending.
-
Spicy: Add 1/4 teaspoon red pepper flakes or a small jalapeño with the garlic.
-
Herbaceous: Toss in a handful of fresh basil or dill before blending.
-
Roasted version: Roast zucchini, onion, and garlic at 400°F (200°C) for 20 minutes first, then simmer in broth for 10 minutes. Deeper flavor, adds 20 minutes.
Storage & Reheating
-
Refrigerator: Airtight container for up to 5 days. Flavor improves on day 2.
-
Freezer: Up to 3 months. Leave 1 inch of headspace in containers. Thaw overnight in fridge.
-
Reheating: Gently warm on stovetop over medium-low heat, stirring occasionally. Add a splash of water or broth if too thick. Avoid boiling after blending (can break the emulsion).
-
Meal prep bonus: Portion into mason jars for grab-and-go lunches.
What to Serve With It
-
Crusty sourdough or garlic bread
-
A simple arugula salad with lemon vinaigrette
-
Grilled cheese sandwich (classic pairing)
-
Toasted pine nuts and a dollop of pesto
Final Note from the Kitchen
This soup has converted more zucchini-haters than any recipe I’ve ever written. The first time I made it, I served it to a friend who said, and I quote, “I would pay money for this in a restaurant.”
It’s proof that simple vegetables, treated with a little patience and a good blender, can become something truly luxurious.
Make it tonight. Make it with overgrown garden zucchinis or the sad ones at the back of your fridge. Make it when you need comfort without heaviness.
Then watch it disappear.
