Ingredients
2 Tbsp unsalted butter
1 Tbsp olive oil
4 large yellow onions, thinly sliced
4 cloves garlic, minced
3 Tbsp all-purpose flour
2 cups beef bone broth
4 cups beef broth
1 Tbsp Worcestershire sauce (ensure alcohol-free)
3 sprigs fresh thyme
1 bay leaf
Instructions
Heat the butter and olive oil in a large pot or Dutch oven over medium-low heat.
Add the sliced onions and cook, stirring occasionally, for 30-40 minutes until they achieve a deep golden, jammy consistency.
Stir in the minced garlic and cook for 1 minute until fragrant.
Sprinkle the flour over the onions and stir for 2 minutes to cook out the raw flour taste.
Slowly pour in both the bone broth and beef broth while whisking constantly.
Add the Worcestershire sauce, thyme sprigs, and bay leaf.
Simmer the soup on low for 15-20 minutes to allow the flavors to meld.
Remove the thyme stems and bay leaf before serving.
Notes
For a classic finish, garnish with a toasted slice of baguette topped with a small amount of melted Gruyere or Swiss cheese, adjusting nutritional values as necessary. Store leftovers in an airtight container in the refrigerator for up to 4 days.
