Bone broth. Onions. Raw milk cheese. Put them together and magic happens…French Onion soup is a classic for a reason. Use the best ingredients for an unforgettable meal.
Beef bone broth recipe. If you cn’t make your own broth, organic, grass fed broth is available–but it won’t be as good as your own.
Traditionally, pieces of a baguette or croutons are placed in soup, but I omitted to make this low carb. However, if it’s a cheat day, serve with a hot baguette!
I served this with tomato salad with pickled onions.
French Onion Soup
6 large onions, thinly sliced
6 cups bone broth, preferably beef, but chicken or vegetable can be substituted
Coupled sprigs thyme
4 tablespoons butter
Salt and pepper
8 ounces cheese, preferably raw like Emmentaler and Swiss Gruyere, sliced
Heat a cast iron casserole or other sturdy pot on medium and melt butter. Add onions. Stirring occasionally, cook them slowly—you may want to lower temperature—until they slowly collapse and begin to brown, 30-45 minutes.
Preheat oven to 400. Add stock, thyme, salt and pepper and bring just to a boil. Cook for 15 minutes.
Ladle soup into portion sized bowls and place on a parchment lined sturdy baking sheet. Place cheese over soup and bake about 10 minutes, or until cheese melts.
