French Onion Soup

I'll admit that I use water most of the time, but when you have vegetable broth on hand, it's a great nutritional addition. I recommend a lightly flavored broth so that the soup maintains the flavor of the onions and balsamic vinegar. The balsamic vinegar I use has no added sugar, which is good for sugar-free diets such as SCD.
 
Servings: 4 servings

Ingredients

  • 3 large yellow onions preferably sweet
  • 2 tablespoons 30 ml olive oil or ghee
  • 2 teaspoons salt split between step 3 and 4
  • 1 garlic clove peeled and minced
  • drizzle of honey optional
  • 3 tablespoons 45 ml balsamic vinegar
  • 6 cups 237 ml water or vegetable broth
  • 1 cup shredded Parmesan or other cheese

Instructions

  • Heat a wide stock pot or dutch oven on low heat.
  • Add the oil and onions to the pot, cover, and cook on a low heat for 15 minutes.
  • Take the top off the pot. Raise the heat slightly and add 1/2 teaspoon salt, garlic, and a drizzle of honey. Cook uncovered for 30 to 40 minutes, occasionally stirring the onions. The onions should be browned but not burnt. Add a drizzle more oil if the onions are sticking to the bottom of the pot.
  • Add the broth or water, 1 1/2 teaspoons of salt, and balsamic vinegar, and simmer for 15 minutes. Feel free to add a bit more salt if needed.
  • Place soup servings in oven-safe soup bowls and sprinkle with Parmesan or Swiss cheese on top.
  • Place the soup bowls in an oven under a broiler or at a broil setting for 2 minutes or so, or until the cheese is bubbling.
  • Serve hot.
  • Store leftover soup in the refrigerator for a few days, or freeze for a few months.
