Recipe Information
Ingredients
- 4 tablespoons unsalted butter
- 4 large yellow onions
- 1 teaspoon salt
- 0.5 teaspoon ground black pepper
- 4 cloves garlic cloves, minced
- 0.5 cup dry white wine
- 6 cups beef broth
- 4 sprigs fresh thyme
- 1 leaf bay leaf
- 1 head cauliflower, cut into small florets
- 2 cups Gruyère cheese, shredded
- 0.5 cup Parmesan cheese, grated
Instructions
Melt the butter in a large, heavy-bottomed pot over medium heat.
Peel and thinly slice the yellow onions. Add them to the pot along with the salt and pepper, and sauté for about 25-30 minutes, stirring occasionally, until the onions are golden brown and fully caramelized.
Stir in the minced garlic and cook for another 2 minutes until fragrant.
Deglaze the pot with the dry white wine, scraping up any browned bits from the bottom. Let the wine reduce to half its volume, approximately 5 minutes.
Add the beef broth, thyme sprigs, and bay leaf to the pot. Bring the mixture to a boil, then reduce the heat and simmer for 20 minutes.
While the soup simmers, steam the cauliflower florets until tender but not mushy, about 8-10 minutes. Set aside.
Preheat your oven to 400°F (200°C).
Remove the thyme sprigs and bay leaf from the soup. Taste and adjust seasoning if needed.
Ladle the soup into oven-safe ramekins or bowls. Add a few cauliflower florets to each bowl as a low-carb alternative to bread croutons.
Top each bowl with a generous portion of shredded Gruyère cheese and a sprinkle of Parmesan cheese.
Place the bowls on a baking sheet for easy handling and bake in the preheated oven for 10-12 minutes, or until the cheese is bubbly and golden brown.
Carefully remove the hot bowls from the oven and let cool slightly before serving. Garnish with a sprig of fresh thyme if desired, and enjoy your low-carb Caramelized Onion Soup Au Gratin!
