The addition of kale to classic French onion soup results in a healthy and hearty comforting soup perfect for lunch or dinner. —SarahLipoff

What You'll Need
  • 4 sliced onions
  • 1 tablespoon vegetable oil
  • 1 teaspoon salt
  • 1/4 teaspoon thyme
  • Dash pepper
  • 1/4 cup dry white vermouth
  • 1 tablespoon soy sauce
  • 1 tablespoon apple cider vinegar
  • 1/4 teaspoon sugar
  • 32 ounces good beef stock
  • 2 cups water
  • 3 cups chopped kale
  • sliced whole-wheat bread
  • Jarlsberg
  1. French onion soup is all about the yummy caramelized onions (well, really, it's about the melty cheese), which is the flavorful base to the soup. Slice the onions in half and then into 1/4-inch half round strips. Heat a large stockpot over medium heat and add the oil, sliced onions, salt, thyme, and dash of pepper. Give things a stir to coat the onions.
  2. Let the onions simmer and caramelize for about 10 to 15-minutes. Keep stirring every few minutes to keep them from burning or sticking to the bottom of your pot. Before you know it, they'll shrink up and start browning around the edges.
  3. Deglaze the pan with the vermouth and stir pulling up all those caramelized bits and mixing them in with those onions. Now you can add the soy, apple cider vinegar, sugar, beef stock and water. Crank the heat and bring to a boil.
  4. Once the French onion soup is bubbling, add the kale and let simmer covered for 20-minutes.
  5. Pre-heat your broiler and dig out an ovenproof bowl, a slice of whole wheat bread, and your cheese. Ladle the hot soup into your bowl and top with a slice of whole-wheat bread (I cut the crusts off to prevent burning) and then cover the bread with two slices of Jarlsberg. Don't have any Jarlsberg hanging around? You can cover with Parmesan or even mozzarella, and this soup is still tasty (I tried both!).
  6. Place the bowl on a sheet tray and then under the broiler. Don't walk away - keep a close eye on your soup! Once the top of the cheese starts bubbling, you're good to go.
  7. Enjoy! (don't burn your mouth!)

It's a good base. I did add some extras to punch it up. Thanks for the kale idea.
