Brown the ground beef in a large pot over medium heat, breaking it up with a spoon until no pink remains. Drain excess fat if needed.
Add the diced onion and minced garlic to the pot. Cook for 3 minutes until the onion softens.
Stir in the Hungarian paprika and cook for 30 seconds to release its flavor.
Add the sliced carrots, green beans, diced potatoes, beef broth, and diced tomatoes. Season with salt and black pepper.
Bring the mixture to a boil, then reduce heat to low. Cover and simmer for 25 minutes until the vegetables are tender.
Taste and adjust seasoning if necessary. Sprinkle with chopped fresh parsley before serving.
