Ingredients

  • 2 Tbsp unsalted butter (30g)
  • 1 Tbsp olive oil (15g)
  • 4 large yellow onions (1112g) thinly sliced
  • 4 cloves garlic minced
  • 3 Tbsp all purpose or gf flour (22g)
  • 2 cups beef bone broth (480g) divided
  • 4 cups beef broth (960g)
  • 1 Tbsp Worcheshire sauce (15g)
  • 3 sprigs fresh thyme or 1 tsp dried thyme
  • 1 bay leaf
  • salt & freshly cracked black pepper to taste
  • French baguette for serving
  • Freshly shredded gruyere cheese for serving

Instructions

Preparing the French Onion Soup:

  • Melt the butter and olive oil in a large dutch oven or pot over medium-high heat. Add the onions and saute for about 30 minutes, or until caramelized. Check and stir every 5 minutes to make sure they’re not burning.
  • Once caramelized, add the garlic and cook for 2 minutes. Stir in the flour and 1 tsp salt (or to taste).
  • Add 1/2 cup of the beef broth to deglaze the pan, scraping up any browned bits on the bottom of the pan.
    Then add in the beef broth, Worcheshire sauce, thyme, bay leaf and the rest of the bone both. Simmer for 15-20 minutes then discard the thyme and bay leaf. Taste and add any salt and/or pepper to taste.

Preparing the Baguette:

  • Meanwhile, while the soup is simmering, preheat the oven to 400F and line a baking sheet with parchment paper.
  • Slice the baguette into 1-inch pieces. Spray both sides of the baguettes with olive oil spray and sprinkle with garlic powder (if desired). Arrange in a single layer on a baking sheet and bake for about 4 minutes on each side or until toasted to your liking.
  • Remove from the oven and sprinkle the cheese evenly on top of all the baguettes. Bake for another 4 minutes or until the cheese is melty.
  • Ladle the soup into bowls. Add a slice of your cheesy baguette on top and serve!
