Tips
Use immersion blender for easy texture control - blend only half the soup to maintain chunky pieces while creating creaminess.
Roasted garlic can be prepared ahead and stored refrigerated for up to a week, making this recipe faster on busy nights.
Save sausage fat for extra flavor - only add oil if there is insufficient fat remaining from browning the sausage.
Good to Know
Refrigerate for up to 4 days in covered container. Reheat gently on stovetop, adding broth if needed to thin.
Roast garlic up to 1 week ahead. Brown sausage and prep vegetables 1 day ahead. Assemble and simmer day of serving.
Ladle into bowls and garnish with fresh parsley. Serve with crusty bread or crackers.
Common Mistakes
Avoid over-blending the soup to maintain chunky texture with potato pieces.
Do not add kale too early to prevent overcooking and mushiness.
