Ingredients
Scale
- 1/2 cup unsalted butter (See NOTES 1 for substitutions)
- 4 medium white onions [sliced]
- 2 medium garlic cloves [finely chopped] (See NOTES 2 for substitutions)
- 2 bay leaves
- 2 fresh thyme sprigs [leaves picked]
- 3 tablespoons all-purpose flour (See NOTES 3 for substitutions)
- 9 cups beef bone broth (See NOTES 4 for substitutions)
- 1 teaspoon beef bouillon paste (See NOTES 5 for substitutions)
- 2 Tablespoon Worcestershire sauce
- Salt [to taste]
- freshly ground black pepper [to taste]
- Mozzarella Croutons [topping]
Instructions
- Melt the butter in a Dutch oven or large stock pot over medium heat.
- Add the onions, garlic, bay leaves, and thyme leaves to the melted butter. Add a good pinch of salt (about a teaspoon). Occasionally stir and cook until the onions are very soft and golden brown. This will take about 30-40 minutes.
- Add 1 cup of broth, bouillon, and Worcestershire sauce, bring to a boil, reduce the heat and simmer until the liquid has evaporated and the onions are “dry”, about 5-10 minutes.
- Discard the bay leaves. Dust the onions with the all-purpose flour and give them a stir. Turn the heat down to medium-low to prevent burning, and cook for 10 minutes to remove the raw flour taste. Now add the rest of the beef bone broth, bring the soup back to a simmer, and cook for 10 minutes. Season to taste, with salt and pepper.
- Optional step: Blend the soup to make it smooth *this will also lighten the color of the soup*
- Ladle the soup in bowls or large mugs and float a couple of the Mozzarella Croutons on top.
