In a large pot, heat the olive oil over medium heat.
Add the sausage and cook until browned, breaking it up with the wooden spoon.
Add the onion, garlic, and fennel. Cook until softened, about 5 minutes.
Stir in the diced potatoes, thyme, salt, and pepper.
Pour in the chicken broth and bring to a simmer.
Cook for about 15 minutes or until the potatoes are tender.
Stir in the milk and adjust seasoning as needed.
Serve hot and enjoy!
Notes
For added creaminess, stir in 1/2 cup of heavy cream just before serving.Feel free to substitute Italian sausage with turkey sausage for a lighter option.If you don't have fennel, you can use leeks for a similar taste!
