Add garlic to the pot and cook for 5 more minutes.
Add all remaining ingredients except for cottage cheese and miso to the pot. Bring to a simmer and cook for about 10 more minutes, until zucchini is softened.
Add soup to a blender along with cottage cheese and miso. Blend until smooth. Serve soup with a grilled cheese or crusty bread.
