Keto French Onion Soup Recipe Ingredients

Toasted Bread Topping:

Top with Gruyere, Swiss, or your favorite cheese to melt on top.


Keto French Onion Soup Recipe Instructions

  1. Slice onions into very thin slices.
  2. Use a large stockpot over medium to high heat. Add the butter and oil to the pan until it’s melted.
  3. Add the sliced onions to the hot pan and mix until the onions are fully coated.
  4. Cook the onions until they start to brown slightly and caramelize. This may take 15 to 20 minutes.
  5. Add the 1/4 cup of dry white wine or apple cider vinegar and scrape the brown color at the bottom of the pan while stirring long enough for most of the liquid to evaporate. This is known as deglazing the pan and it releases the brown bits that are full of flavor into the onions. This will only take a couple of minutes.
  6. Add the beef broth, thyme, Worcestershire sauce, salt, and pepper.
  7. Taste and add more salt and pepper if needed.
