Gluten-Free French Onion Soup

Tip: To prevent cracking, don’t place ramekins or bowls too close to the broiler if you don’t know their temperature rating. Keep a close watch while broiling to prevent over-browning.  

This rich and delicious recipe takes some time to come together. However, the results are well worth it. The richly caramelized onions and slowly simmered broth are incredible.

Prep time: 20 minutes
Cook time: 3+ hours
Serves: 4

Ingredients:

¼ of a cup of unsalted butter
900 grams of yellow onions, trimmed and sliced root to tip
Sea salt and black pepper, to taste
½ a cup of dry red wine
2 tablespoons of balsamic vinegar
4 cups of beef broth, preferably organic
2 whole bay leaves
2 teaspoons of Italian seasoning
1 teaspoons of garlic powder
4-5 sprigs, fresh thyme
170 grams of Gruyère cheese, sliced thin
½ a cup of Parmesan cheese, freshly grated

Process:

1. Heat butter in a large, high-sided skillet over medium heat. Add sliced onions and season with salt and black pepper, to taste. Stir to combine. Cook, stirring occasionally, until caramelized, approximately 45 minutes to one hour.
   
   
2. Deglaze the bottom of the pan by adding the red wine and balsamic vinegar and gently scraping the browned bits off the bottom with a spatula.
   
   
3. Add the broth, bay leaves, Italian seasoning, garlic powder, and sprigs of fresh thyme. Season with additional salt and black pepper, if desired, and stir to combine.
   
   
4. Increase heat to high and bring to a rapid bowl, then immediately reduce heat to medium-low. Loosely cover the skillet with a lid and simmer, stirring occasionally, for two hours.
   
   
5. Remove from heat and discard the thyme stems and bay leaves. Divide the soup between four large oven-safe ramekins or bowl. Top with slices of the Gruyère cheese, followed by the freshly grated Parmesan cheese.
   
   
6. Place top oven rack in the second position from top and set the broiler to high.
   
   
7. Arrange ramekins on a large, rimmed baking sheet and place on the top oven rack. Broil until the cheese is melted and golden brown, approximately 8-10 minutes. Remove from oven and serve immediately garnished with a few fresh thyme leaves.
