Follow these simple steps to create your own delicious Polish Potato Soup:

1. Sauté Onions and Garlic: In a large pot, melt the butter over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes. Add the minced garlic and cook for an additional 1-2 minutes, stirring frequently.
2. Add Potatoes and Broth: Stir in the diced potatoes, thyme, salt, and pepper. Pour in the vegetable or chicken broth, bringing the mixture to a boil.
3. Simmer: Once boiling, reduce the heat to low and let the soup simmer for 25-30 minutes, or until the potatoes are tender.
4. Blend the Soup: Using an immersion blender, blend the soup until smooth. If you prefer a chunkier texture, blend only half of the soup and leave the rest as is.
5. Add Cream: Stir in the heavy cream (or milk) and heat the soup until warmed through. Adjust seasoning if necessary.
6. Serve: Ladle the soup into bowls and garnish with fresh parsley.
