Making Creamy Potato Soup is straightforward if you follow these steps:

1. Melt Butter: In a large pot, melt the butter over medium heat.
2. Sauté Onion and Garlic: Add the chopped onion and minced garlic to the pot. Sauté until the onion becomes translucent, about 4-5 minutes.
3. Add Potatoes: Stir in the diced potatoes, mixing them well with the onion and garlic for about 2 minutes.
4. Add Broth: Pour in the vegetable broth, ensuring the potatoes are fully submerged. Bring the mixture to a boil.
5. Simmer: Reduce the heat to low and let it simmer for 20-25 minutes, or until the potatoes are fork-tender.
6. Blend the Soup: Use an immersion blender or transfer the soup in batches to a regular blender. Blend until smooth and creamy, adjusting the consistency with more broth or water if needed.
7. Stir in Cream and Seasonings: Return the blended soup to the pot. Stir in the heavy cream, dried thyme, salt, and black pepper. Heat through for an additional 5 minutes.
8. Taste and Adjust Seasonings: Taste the soup and adjust the salt and pepper as necessary.
9. Serve Hot: Ladle the soup into bowls, and if desired, top with shredded cheese and a sprinkle of chopped chives or parsley.
