Italian Penicillin Soup
Italian Penicillin Soup is a warm, comforting, and nourishing soup that’s like a classic chicken soup with an Italian twist. It’s packed with tender chicken, hearty orzo, and fresh kale, all simmered in a flavorful broth infused with garlic, thyme, and bay leaf. The name comes from its healing qualities—similar to traditional “Jewish penicillin” (chicken soup)—but with an Italian flair, thanks to ingredients like orzo and Parmesan.

I made this in my crockpot and it turned out wonderful! I did sub a sweet potato for the carrots and spinach for the kale since we prefer those. My husband complimented it several times! Will make it again!
I love that your husband complimented it! That always feels so validating.
