Ingredients
Method
- Heat olive oil in a large pot over medium-high. Add sausage, break it up, and cook until browned, 5–6 minutes. Transfer to a plate, leaving drippings.
- Add onion, carrots, and celery to the pot with a pinch of salt. Cook until softened, 5 minutes. Add garlic and cook 1 minute.
- Return sausage to the pot with broth, tomatoes, potatoes, oregano, and red pepper flakes. Bring to a boil, then simmer until potatoes are tender, 15–20 minutes.
- Stir in green beans and cook 5 minutes. Remove Parmesan rind if used. Season with salt and pepper, ladle into bowls, and top with grated Parmesan.
Notes
The soup thickens as it sits, so you may need to add a little broth when reheating. If you freeze it, expect the potato texture to soften but the flavor to stay rich.
