Prepare the vegetables by trimming the green beans and cutting them into 1- to 2-inch pieces. Peel the potatoes and chop them into 1-inch chunks to ensure they cook evenly. Slice the kielbasa into ½-inch pieces.

Place the chopped green beans, potatoes, and sliced kielbasa into the slow cooker. Pour the chicken broth over the ingredients, making sure the vegetables are evenly moistened.

Sprinkle the onion powder, garlic powder, salt, and black pepper over the mixture. Stir everything thoroughly to distribute the seasonings and broth evenly throughout the slow cooker.

Cover the crockpot with the lid and cook on HIGH for 4 hours or LOW for 6 hours, until the potatoes are fork-tender, the green beans are perfectly cooked, and the kielbasa is heated through and infused with the savory broth.

Give the mixture a gentle stir before serving to redistribute the flavorful cooking liquid. Taste and adjust the seasoning with additional salt or pepper if desired.

Serve the kielbasa, green beans, and potatoes as a hearty one-pot meal, or spoon it over cooked rice or buttered egg noodles for an even more filling dinner. For a fresh finishing touch, garnish with chopped parsley if desired.

Tip: If you prefer a slightly thicker, stew-like consistency, lightly mash a few of the cooked potatoes into the broth just before serving. This naturally thickens the cooking liquid while adding extra creaminess.
