If you’re using fresh green beans, wash them, trim them, and chop them into bite-size pieces. Prepare onion and garlic.
Heat the oil in a large pot over medium heat. Add the onion and sauté for 3-4 minutes until translucent.
Add the finely chopped garlic. Cook for 1 minute, stirring constantly, until fragrant (avoid browning).
Add the ground paprika and the green beans. Cook for 1 minute, stirring constantly, until the paprika blooms and releases its aroma (but watch out not to brown the paprika or it will taste bitter).
Pour in the vegetable broth and add the lovage (sprigs or dried amount). Bring the soup to a full boil, then immediately reduce the heat to low. Cover with a lid and simmer until the green beans are tender-crisp (about 10-15 minutes).
Turn off the heat. Remove and discard the fresh lovage sprigs. Stir in the freshly chopped parsley and dill.
Taste the soup and add salt and pepper as needed. Serve warm.
