Prepare the vegetables: Wash and chop the beetroot leaves, if using with small beetroots, wipe them clean; chop potatoes, carrots and onions. Chop the garlic.
Saute the onion and garlic: Heat the olive oil in the soup pot and saute the onion and garlic until soft and fragrant (about 5-7 minutes).
Add the carrots: Add the carrots to the pot, mix well and fry for a few more minutes.
Pour the broth and potatoes: Pour the meat or vegetable broth, add the potatoes, add the bay leaf, bring to a boil and reduce the heat. Cook for about 15-20 minutes until the potatoes are tender.
Add the beetroot leaves: When the potatoes and carrots are soft, add the chopped beetroot leaves to the soup.
Season and cook: Add salt and pepper to taste. Cook for another 5-7 minutes until the leaves are tender.
Serving: Serve the soup with sour cream and fresh herbs, very tasty with parsley or dill.
