Prep work: Dice onions, carrots, celery, zucchini, and sweet potatoes uniformly. Mince ginger finely. Organize all ingredients before starting .
Base preparation: Heat olive oil in large pot over medium heat. Cook diced onions until slightly caramelized (5-7 minutes). Add minced ginger and cook for one additional minute.
Vegetable cooking: Add diced vegetables and cook for 5 minutes until slightly softened but still crisp. Add sweet potatoes and optional turmeric (fresh or powder). Stir to coat vegetables evenly.
Broth addition: Add water (or vegetable/chicken broth for stronger flavor). Reduce heat to maintain steady simmer. Cover and cook for about 15 minutes or until vegetables are fork-tender.
Finishing steps: Add fresh parsley and simmer for one minute. Let broth cool slightly before blending until creamy.
Final touches: Return blended soup to pot. Add coconut milk, salt, and pepper. Simmer uncovered for 5 additional minutes to meld flavors.
Serving: Garnish with a splash of coconut milk on top for visual appeal.
