This high-protein sausage and kale soup is a deeply satisfying dish that balances savoury fennel-infused meat with earthy greens. The secret ingredient here is a small amount of cornmeal, which dissolves into the broth to provide a beautiful silky texture and a subtle hint of sweetness. It is a wonderful way to enjoy seasonal kale or chard, creating a vibrant, nutritious bowlful that feels both rustic and refined.
Perfect for a restorative midweek meal, this versatile soup provides a fantastic boost of protein and fibre. While the fennel sausage provides a robust base, the addition of Parmigiano-Reggiano adds a salty, umami finish that brings all the flavours together. Serve it in deep bowls with a crusty piece of sourdough for a complete and wholesome homemade dinner.

How to make Michael Romano's Secret-Ingredient Soup
Back to contentsHeat the oil in a large saucepan over medium heat. Add the onion, carrot, leeks, garlic, salt, black pepper, and Aleppo pepper and cook, stirring, until the onion becomes translucent, 8 to 10 minutes. Add the sausage and cook, breaking it up into small pieces with a wooden spoon, until no longer pink, about 5 minutes.
Drain off the excess fat, leaving about 2 tablespoons in the pan. Stir in the cornmeal. Add the stock, stirring, and bring to a boil, then reduce the heat and simmer, covered, for 30 minutes, stirring occasionally.
Stir in the greens and cook for 15 minutes more, or until tender.
Ladle into bowls and garnish with grated Parmigiano.
