Cook the chopped bacon in a large pot over medium heat until crisp. Remove the bacon with a slotted spoon and set it aside, leaving the fat in the pot.
Add the ground beef to the bacon fat and cook until browned, breaking it up with a spoon as it cooks.
Stir in the onion and cook for 3 minutes until it softens.
Add the carrots, potatoes, and parsnip. Cook for 2 minutes, stirring to coat the vegetables in the fat.
Sprinkle in the smoked paprika, salt, and pepper, then pour in the beef broth. Bring the mixture to a simmer.
Cover and cook for 20 minutes until the root vegetables are tender.
Stir in the green beans and reserved bacon. Simmer uncovered for 5 more minutes until the beans are bright and crisp-tender.
