Our adoration for soup keeps me constantly seeking new recipes to add to the rotation, and today I’m sharing with you one I am especially fond of: French Onion Soup. A classic, this recipe marries the deep, rich flavors of caramelized onions with savory beef broth. Crowned with melty Gruyère cheese and served alongside French bread, it’s the most gourmet of treats – served right in the comfort of your own home.

Then, just grab it from the freezer, put it in your slow cooker or Instant Pot, and without any further effort from you, you’ll have the most irresistible of dinners ready in no time.
