Stir in the minced garlic and red pepper flakes, cooking for another minute. Add the chopped zucchini, tossing it well to coat with the oil and spices, and cook for about 4 minutes until it starts to soften.
Pour in the broth and bring the mixture to a gentle simmer. Let it cook for 15 to 20 minutes until the zucchini is completely tender and easy to pierce.
Turn off the heat, then stir in the fresh basil leaves and grated parmesan, letting the basil wilt slightly. Carefully blend the soup using an immersion blender until it is silky smooth.
Stir in the heavy cream, season with additional salt and pepper to your liking, and serve this delicious, nutrient-rich soup either hot or chilled!
