Ingredients
- 2 tablespoons olive oil or butter
- 1 medium yellow onion, chopped
- 2–3 cloves garlic, minced
- 1 kilogram (about 2 pounds) zucchini, chopped (no need to peel)
- 1 medium potato, peeled and diced (optional, for extra creaminess)
- 4 cups vegetable or chicken broth
- 1/4 cup heavy cream, half-and-half, or plain Greek yogurt (optional)
- 1 teaspoon dried thyme or Italian seasoning
- 1–2 tablespoons fresh lemon juice
- Salt and freshly ground black pepper, to taste
- Fresh herbs for garnish: chives, parsley, or basil (optional)
- Grated Parmesan, toasted seeds, or a drizzle of olive oil for serving (optional)
Step-by-Step Instructions
- Sauté the aromatics: In a large pot, warm the olive oil or butter over medium heat. Add the onion with a pinch of salt.
Cook 4–5 minutes, stirring occasionally, until softened and translucent. Add the garlic and cook 30 seconds, just until fragrant.
- Add zucchini and potato: Stir in the chopped zucchini and potato (if using). Season with salt, pepper, and thyme.
Cook 3–4 minutes to soften the edges and build flavor.
- Pour in the broth: Add the broth and bring to a gentle boil. Reduce heat to a simmer, cover halfway, and cook 12–15 minutes, until the zucchini and potato are very tender.
- Blend until smooth: Turn off the heat. Using an immersion blender, blend directly in the pot until silky.
Or carefully transfer to a blender in batches. Blend until smooth and creamy.
- Finish with cream and lemon: Return the soup to low heat if needed. Stir in the cream or yogurt, then add lemon juice to brighten the flavor.
Taste and adjust salt and pepper.
- Serve and garnish: Ladle into bowls. Top with fresh herbs, a drizzle of olive oil, a sprinkle of Parmesan, or toasted seeds for crunch.
Keeping It Fresh
- Store: Let the soup cool, then refrigerate in an airtight container for up to 4 days. If you used yogurt, add it just before serving to keep the texture smooth.
- Freeze: Freeze in portions for up to 3 months.
Skip the dairy before freezing; stir it in after reheating for the best consistency.
- Reheat: Warm gently on the stove over low to medium heat, stirring often. Add a splash of broth or water if it thickens.
Benefits of This Recipe
- Nutrient-rich: Zucchini brings fiber, vitamin C, and hydration, while onion and garlic add antioxidants and depth.
- Customizable: You can keep it dairy-free, boost protein with beans, or add greens without changing the soul of the dish.
- Budget-friendly: All ingredients are affordable and widely available.
- Family-friendly: Mild flavor and silky texture make it appealing for both kids and adults.
- Meal-prep ready: It reheats well and tastes even better the next day as the flavors meld.
Common Mistakes to Avoid
- Overcooking the garlic: Burnt garlic tastes bitter. Add it after the onion softens and cook briefly.
- Skipping seasoning layers: Salt lightly at each step—onion, then zucchini, then at the end—to build balanced flavor.
- Blending too soon: If the zucchini isn’t tender, you’ll get a grainy texture.
Simmer until everything is soft.
- Adding dairy before blending hot soup: High heat can cause curdling, especially with yogurt. Temper dairy by stirring it in off heat.
- Forgetting acidity: A splash of lemon juice brightens the soup and keeps it from tasting flat.
Variations You Can Try
- Dairy-free: Skip cream and add a small potato or a handful of cashews (simmer with the soup) for body.
- Protein boost: Blend in 1/2 cup cooked white beans or add shredded rotisserie chicken after blending.
- Herb-forward: Swap thyme for fresh basil and finish with a spoonful of pesto.
- Spice it up: Add a pinch of red pepper flakes, curry powder, or smoked paprika when sautéing the onion.
- Green machine: Blend in a handful of spinach or kale at the end for a deeper green color and extra nutrients.
- Extra creamy: Stir in cream cheese or mascarpone instead of cream for a richer finish.
- Crunchy toppings: Garnish with croutons, crispy prosciutto, roasted chickpeas, or toasted pumpkin seeds.
FAQ
Do I need to peel the zucchini?
No. The skin softens as it cooks and blends smoothly.
It also adds color and nutrients, so leave it on unless the zucchini is very large and tough.
Can I make this without a blender?
You can use a potato masher for a rustic texture, but for that classic creamy finish, an immersion blender or regular blender works best.
How do I keep yogurt from curdling?
Let the soup cool slightly, then whisk in the yogurt off the heat. You can also temper it by mixing a ladle of warm soup into the yogurt first, then stirring it back into the pot.
What’s the best broth to use?
Use vegetable broth for a vegetarian version or chicken broth for a richer flavor. Choose a low-sodium option so you can control the salt.
Can I use frozen zucchini?
Yes.
Sauté it straight from frozen with the onion and garlic to drive off extra moisture, then proceed as usual. The texture will still turn out smooth.
How can I thicken the soup without cream?
Add a diced potato, a handful of cashews, or 1/2 cup cooked white beans before simmering. Blend until silky for a naturally creamy texture.
Is this soup good served cold?
It can be.
Chill it thoroughly, then adjust seasoning and add a little lemon juice before serving. Top with herbs and a drizzle of olive oil.
What protein pairs well on the side?
Grilled chicken, a simple omelet, or crusty bread with cheese make easy partners. For a vegetarian option, try a chickpea salad or avocado toast.
