01 - In a large pot, heat olive oil over medium heat. Add diced onion and minced garlic, sautéing for 2 to 3 minutes until fragrant.
02 - Add carrots, celery, and diced potato. Cook for 5 minutes, stirring occasionally to prevent sticking.
03 - Stir in zucchini, green beans, and peas. Continue to cook for an additional 2 minutes.
04 - Pour in vegetable broth and add dried thyme, dried parsley, bay leaf, salt, and black pepper. Bring mixture to a boil.
05 - Reduce heat to low and simmer uncovered for 20 to 25 minutes, or until all vegetables are tender.
06 - Remove the bay leaf, then blend the soup directly in the pot using an immersion blender until smooth, or blend in batches using a countertop blender if preferred. Some texture can be retained if desired.
07 - Stir in heavy cream or coconut milk and heat gently for 2 to 3 minutes. Adjust seasoning to taste.
08 - Ladle soup into bowls, garnish with chopped fresh parsley if desired, and serve hot.
