Start by adding sliced kielbasa, fresh green beans, halved baby potatoes, and chopped onions to your crockpot.
Sprinkle minced garlic along with garlic powder, onion powder, smoked paprika (if using), salt, and pepper over the top of your ingredients.
Pour chicken broth over everything in the crockpot and dot with butter pieces.
Cover the crockpot and cook on low for about 6 to 7 hours or on high for about 3 to 4 hours until the potatoes are tender.
Gently stir halfway through cooking and sprinkle with fresh parsley and grated Parmesan cheese if desired before serving.
