Ingredients

4 large yellow onions, thinly sliced

4 tbsp unsalted butter

1 tsp salt

1/2 tsp black pepper

1/4 cup dry white wine or dry sherry (optional, for deglazing)

6 cups beef broth (low sodium, sugar-free)

2 sprigs fresh thyme

1 bay leaf

1/2 tsp xanthan gum (optional, for slight thickening)

6 slices keto bread or fathead dough crackers, toasted

6 oz Gruyere cheese, shredded

Method

In a large Dutch oven or heavy-bottomed pot, melt the butter over medium-low heat. Add the sliced onions, salt, and pepper.

Cook the onions, stirring occasionally, for 45-60 minutes, or until deeply caramelized and a rich golden-brown color. This process cannot be rushed.

If using, deglaze the pot with white wine or sherry, scraping up any browned bits from the bottom. Cook for 2-3 minutes until the liquid has mostly evaporated.

Pour in the beef broth, add the fresh thyme sprigs and bay leaf. Bring to a simmer, then reduce heat to low, cover, and cook for at least 20-30 minutes to allow flavors to meld.

If desired, whisk in 1/2 tsp xanthan gum (mixed with a tablespoon of cold water first to prevent lumps) to slightly thicken the soup. Simmer for another 5 minutes.

Preheat your broiler. Remove the thyme sprigs and bay leaf from the soup.

Ladle the hot soup into oven-safe bowls. Place a slice of toasted keto bread or cracker on top of each bowl, then generously sprinkle with shredded Gruyere cheese.

Broil for 2-4 minutes, watching carefully, until the cheese is bubbly and golden brown. Serve immediately.
