Ingredients
6 Tbsp salted butter
4 medium yellow onions, thinly sliced
3 garlic cloves, minced
2 cups cremini or wild mushrooms, sliced
2 Tbsp fresh thyme leaves
2 Tbsp chopped fresh sage
1 tsp honey (or skip if not using honey)
6–8 cups low-sodium chicken or vegetable broth
2 tsp Worcestershire sauce
2 bay leaves
Kosher salt & black pepper, to taste
½ cup heavy cream
Optional Garnish: French bread slices topped with Gruyère cheese, broiled until bubbly
Instructions
Caramelize Onions
Melt butter in a large pot over medium-high heat. Add onions and honey. Cook, stirring occasionally, until deeply golden (about 15–20 minutes).
Add Garlic & Mushrooms
Stir in garlic, mushrooms, thyme, and sage. Cook until mushrooms soften and release their juices (~5 minutes).
Simmer the Soup
Pour in broth, Worcestershire sauce, and add bay leaves. Bring to a simmer and cook ~20 minutes. Remove bay leaves.
Finish with Cream
Lower heat and stir in heavy cream. Season with salt and pepper to taste.
Serve
Ladle into bowls. For a cheesier finish, top with slices of bread and Gruyère, then broil until melted and golden.
