Ingredients

4 servings

2 lbs (approx 4 medium) fresh zucchini (courgettes), sliced into ½-inch coins
1 large yellow onion or shallot, chopped
4 cloves garlic, peeled and smashed
3 tbsp extra virgin olive oil (divided)
3 cups low-sodium vegetable broth or chicken broth

⅓ cup freshly grated Parmigiano-Reggiano or heavy cream

Step-by-Step Instructions

Preheat oven to 425°F (220°C). Toss sliced zucchini coins and garlic cloves with 2 tablespoons olive oil, salt, and black pepper on a large rimmed sheet pan. Roast for 20 minutes until golden brown and caramelized around the edges.

In a heavy Dutch oven, heat remaining 1 tablespoon olive oil over medium heat. Add chopped onion and sauté for 5 minutes until soft and translucent. Add roasted zucchini, garlic, and vegetable broth. Bring to a gentle boil.

Remove soup from heat. **Toss in fresh sweet basil leaves**. Using an immersion blender (or transferring in batches to a high-speed blender), **blend on high for 2 minutes** until completely velvety, silky, and bright green.

Stir in freshly grated Parmigiano-Reggiano cheese. Taste and adjust seasoning with extra sea salt or black pepper. Ladle into bowls and **garnish with a swirl of olive oil and fresh basil leaves**!

Chef Amara’s Kitchen Secrets & Pro Tips

Chef's Secret for Deep Flavor: Roasting the zucchini in a hot 425°F oven caramelizes the natural sugars, creating a rich savory flavor impossible to achieve by just boiling raw zucchini.
No Heavy Cream Needed: High-speed blending roasted zucchini with parmesan creates a naturally luxurious, velvety texture without needing heavy cream.
Dairy-Free & Vegan Option: Omit parmesan cheese and substitute 2 tablespoons of nutritional yeast for an equally savory vegan version.

1. Verify Safe Internal Temperature: Use an instant-read digital thermometer in the thickest section of poultry to reach exactly 165°F (74°C). Pulling it the moment it hits temperature keeps lean meat juicy and prevents drying out. 2. Protect Minced Garlic from Burning: Garlic cooks and turns fragrant in just 30 to 45 seconds. Add it toward the end of sautéing onions or aromatics so it perfumes the dish without acquiring a bitter edge. 3.

Troubleshooting & Quick Fixes

▾

What if My Creamy Roasted Zucchini Soup Vegetables Turn Soggy Instead of Crisp?: Avoid crowding your skillet or roasting pan. Trapped steam makes veggies soggy. Spread them across the pan with space between pieces so moisture evaporates and edges caramelize.
How to Deepen Savoriness Without Heavy Salt?: Add a splash of tamari, nutritional yeast, roasted garlic, or smoked paprika. These natural umami boosters satisfy the palate while keeping sodium in check.
