In a large pot over medium heat, brown the ground sausage until fully cooked.

Add chopped onion and minced garlic; sauté until the onions are translucent.

Stir in diced potatoes and chicken broth. Bring to a boil, then reduce heat and simmer until potatoes are tender (about 10–15 minutes).

Mix in cream cheese until melted and fully incorporated.

Gradually add shredded cheddar cheese while stirring until melted.

Serve hot, garnished with sliced green onions.
