In a large soup pot, heat olive oil over medium heat. Add sausage and cook until browned, breaking it up as it sizzles.
Toss in the onion and garlic. Cook until the onion gets soft and translucent—about 5 minutes.
Add chicken broth and sliced potatoes. Bring it all to a low boil and let it cook for 10-12 minutes, or until potatoes are fork-tender.
Reduce heat. Stir in the kale and let it wilt down, about 2 minutes.
Pour in the cream and Parmesan. Stir gently until the cheese melts into creamy goodness.
Taste it. Add salt, pepper, or red pepper flakes to match your vibe.
Serve hot, with crusty bread or straight from the pot—we’re not judging.
