Instructions

1. Step 1: In a large pot, combine 1 cup chopped carrot peels, 1/4 cup finely chopped celery leaves, 1 diced medium onion, 1 cup diced potatoes, and 2 minced garlic cloves; sauté over medium heat for 5 minutes until onions are translucent and vegetables release moisture.
2. Step 2: Add 4 cups vegetable broth, 1/2 tsp dried thyme, 1/4 tsp dried rosemary, 1/2 tsp salt, and 1/4 tsp black pepper; bring to a gentle simmer and cook uncovered for 20 minutes until potatoes are fork-tender.
3. Step 3: Use an immersion blender to puree the soup until smooth (or transfer to a blender in batches), then return to low heat for 2 minutes to thicken slightly.
4. Step 4: Taste and adjust seasoning with additional salt or pepper, then serve hot with a sprinkle of fresh herbs if available.
