1-First Steps: Mise en Place and Prepping: Wash and strip the kale leaves from stems; stack and roll them into tight bundles and slice into very thin ribbons. Peel and cube the potatoes into uniform 1-inch pieces to ensure even cooking. Chop the onion and mince the garlic cloves. If you’re using sausage, slice it thinly. Having everything ready makes this process smooth for your green soup.

2-Cooking the Aromatics and Potatoes: Heat the olive oil in a large pot over medium heat and add the sausage slices, cooking until lightly browned, about 3 to 5 minutes. Remove the sausage and set it aside, keeping the fat in the pot. Add the diced onion with a pinch of salt and cook until translucent, about 5 to 7 minutes, then stir in the garlic and cook for 2 more minutes. Next, add the potatoes and water or stock mixture, bring to a boil, and simmer until potatoes are nearly tender, about 10 to 20 minutes.

3-Blending and Adding Greens: Let the soup cool slightly, then purée it until smooth using an immersion blender or food processor. Return the soup to the pot, add the thinly sliced greens, bring back to a boil, and simmer until the greens are tender, 2 to 5 minutes. Stir in the reserved sausage and season with salt and pepper to taste.

4-Finishing and Serving: Ladle the soup into bowls and garnish with the sausage slices. The total prep time is 25 minutes, cook time is 40 minutes, and you’ll have a comforting dish in about 1 hour 5 minutes. For added flavor, let it rest for a bit before serving. Here are some tips: slice greens into very thin strips to soften quickly, use a mix of water and stock for richness, and avoid curly kale for better texture.
