01 - In a large pot, heat olive oil over medium heat. Add diced onion and minced garlic; cook for 2 to 3 minutes until fragrant and softened.
02 - Incorporate carrots, celery, and potato into the pot. Sauté for 5 minutes, stirring occasionally to prevent sticking.
03 - Stir in diced zucchini, green beans, and peas. Continue to cook for an additional 2 minutes.
04 - Pour in vegetable broth. Season with dried thyme, dried parsley, bay leaf, salt, and black pepper. Increase heat and bring to a boil.
05 - Reduce heat to low and simmer uncovered for 20 to 25 minutes, or until all vegetables are fully tender.
06 - Discard the bay leaf. Using an immersion or countertop blender, purée the soup until smooth, or leave some texture for a rustic finish if preferred.
07 - Stir in heavy cream or coconut milk and gently reheat for 2 to 3 minutes. Taste and adjust seasoning with additional salt or pepper as needed.
08 - Ladle soup into bowls, garnish with chopped fresh parsley if desired, and serve hot.
