Start by chopping the kielbasa into bite-sized pieces, dicing the potatoes into cubes, and finely chopping the onion. Mince the garlic.

In a large pot over medium heat, add a splash of oil and sauté the diced onion and minced garlic until soft and translucent, about 3-4 minutes.

Add the chopped kielbasa to the pot and sauté for about 5-7 minutes until golden brown.

Stir in the diced potatoes and seasonings; mix everything well for about 2 minutes to coat the potatoes evenly.

Pour in the chicken or vegetable broth, covering the ingredients, and increase heat to high until boiling.

Once boiling, reduce the heat to low, cover the pot, and simmer gently for about 20-25 minutes until potatoes are fork-tender.

Remove from heat and stir in cream cheese and shredded cheddar cheese until melted and creamy.

Taste and adjust seasoning with additional salt and pepper before serving.
