Creating German Green Bean Soup is straightforward. Follow these steps for a delicious bowl of comfort:

1. Prepare the Vegetables: Wash, trim, and cut the green beans, peel and dice the potatoes, and finely chop the onion.
2. Sauté the Aromatics: In a large stockpot, heat olive oil or butter over medium heat. Add the chopped onion and garlic, sautéing until translucent and fragrant (about 5 minutes).
3. Add the Potatoes: Stir in the diced potatoes and cook for an additional 5 minutes, allowing them to gain some color.
4. Add Broth and Spices: Pour in the vegetable or chicken broth, and add the dried thyme, salt, and pepper. Bring the mixture to a boil.
5. Cook the Vegetables: Once boiling, reduce the heat to low and add the green beans. Simmer for 20-30 minutes, or until the potatoes and green beans are tender.
6. Blend (Optional): For a creamier texture, use an immersion blender to puree part of the soup, then stir to combine.
7. Taste and Adjust: Taste the soup and adjust the seasonings, adding more salt, pepper, or herbs as desired.
8. Serve: Ladle the soup into bowls and garnish with freshly chopped parsley. Add diced ham or sausage if using.

These steps will guide you through creating a delicious German Green Bean Soup that your whole family will love.
