Place your stockpot over medium heat and add the sausage. Break it up with your wooden spoon as it cooks until browned evenly. Toss in the diced onion and sauté until softened and fragrant. Stir in the garlic and cook for about 1 minute to release its aroma without burning.
Pour in the chicken stock, scraping the bottom of the pot to loosen those delicious brown bits. These add depth and flavor to your soup. Bring the mixture to a gentle simmer before moving to the next step.
Stir in the gnocchi and kale. Let them simmer until the gnocchi floats to the top, which means it’s perfectly cooked. The kale will soften and turn a deep green, adding freshness to every bite.
Lower the heat and slowly add the heavy cream, stirring until it blends into a silky, rich broth. Season with salt and pepper, tasting as you go so you don’t over-season.
Ladle the soup into bowls, top with freshly grated Parmesan cheese, and garnish with fresh herbs or crumbled bacon if you want a little extra indulgence. Serve hot with crusty bread for dipping.
