Ingredients
4 medium zucchinis, chopped
1 medium onion, diced
2 cloves garlic, minced
4 cups vegetable broth
1 cup heavy cream or full-fat coconut milk
½ cup fresh basil leaves, chopped
2 tablespoons olive oil
Salt and pepper to taste
Grated Parmesan cheese for serving (optional)
Instructions
Step 1: Sauté the Aromatics
In a large pot, heat olive oil over medium heat. Add diced onion and sauté until translucent, about 4–5 minutes. Stir in garlic and cook for another 30–60 seconds until fragrant.
Step 2: Cook the Zucchini
Add the chopped zucchini and cook for about 5 minutes, allowing it to soften slightly.
Step 3: Simmer
Pour in the vegetable broth and bring to a gentle boil. Reduce heat and simmer for 15 minutes, until the zucchini is completely tender.
Step 4: Blend Until Smooth
Use an immersion blender to puree until silky smooth. (Or carefully blend in batches using a countertop blender.)
Step 5: Finish & Season
Stir in the cream or coconut milk and fresh basil. Season with salt and pepper to taste. Heat gently for 2–3 minutes to bring everything together.
Step 6: Serve
Ladle into bowls and garnish with grated Parmesan, extra basil, cracked black pepper, or a drizzle of olive oil.

Frequently Asked Questions
Can I make this zucchini and basil soup dairy-free?
Yes! Simply use full-fat coconut milk instead of heavy cream and skip the Parmesan garnish. The coconut milk keeps the soup creamy while adding a subtle richness that pairs beautifully with basil.
Can I use dried basil instead of fresh?
Fresh basil is strongly recommended for this recipe because it provides the bright, fresh flavor that makes the soup shine. If you must substitute, use 1–2 teaspoons dried basil, but the flavor will be more muted.
Can I serve this soup cold?
Absolutely. This soup works wonderfully chilled, especially in warmer months. Let it cool completely, refrigerate for at least 2 hours, and serve with a drizzle of olive oil and extra fresh basil.
How do I thicken the soup if it’s too thin?
If the soup feels too thin, simmer it uncovered for a few extra minutes to reduce. You can also blend in a small amount of white beans or add a spoonful of blended cottage cheese for extra thickness and protein.
How do I make it more filling?
To turn this into a more substantial meal, serve it with whole-grain toast, grilled chicken or a protein wrap.
