Traditional French Onion Soup
Traditional French onion soup has a rich beef broth and some variation of red wine added. The dish I’ve created has chicken broth and white wine for a lighter pairing with diced chicken in this pasta dish.
By all means, if you have beef broth and red wine, try adding those to your dish and let me know how it tastes in the comments!

Add white wine, sour cream, chicken broth, half of the mozzarella, thyme, 1 teaspoon salt, and ½ teaspoon black pepper. Bring to a simmer for 5 minutes.
