Homemade soup has always been one of my favorite things to make, especially when the weather turns cold. This Italian sausage soup is simple, hearty, and built around everyday ingredients you likely already have on hand. It's inspired by old-fashioned, Tuscan-style cooking, where soups were made with whatever was available. It's totally comforting and satisfying.

The idea came together on a night when the pantry offered little more than potatoes and a package of sausage originally meant for breakfast. With a few vegetables added in, this sausage potato soup quickly became a one-pot dinner that delivered big flavor with minimal effort. Finished with fresh parsley and grated Parmesan, it's the kind of cozy meal that tastes even better the next day. It fits right along side comfort food favorites like Pasta Bolognese, Traditional Beef Stroganoff, and Creamy Tomato Soup.
