This Creamy French Onion and Mushroom Soup is a rich and cozy twist on the classic French onion soup, featuring deeply caramelized onions, earthy mushrooms, fresh herbs, a splash of white wine, and a cheesy bread topping.

Ingredients

Scale
  • 6 tablespoons salted butter
  • 4 medium yellow onions, thinly sliced
  • 1 teaspoon honey
  • 1 1/4 cups dry white wine (divided)
  • 3 cloves garlic, minced
  • 2 cups cremini or wild mushrooms, sliced
  • 2 tablespoons fresh thyme leaves
  • 2 tablespoons chopped fresh sage
  • 6–8 cups low sodium chicken or vegetable broth
  • 2 teaspoons Worcestershire sauce
  • 2 bay leaves
  • Kosher salt and black pepper, to taste
  • 1/2 cup heavy cream
  • 6 slices French bread
  • 2 cups shredded Gruyère cheese

Instructions

  1. Melt butter in a large Dutch oven over medium-high heat. Add onions and honey, stir and cook for 10 minutes until softened.
  2. Gradually add 3/4 cup of wine, 1/4 cup at a time, letting it cook down before adding more. Continue cooking for another 10–15 minutes until onions are deeply caramelized.
  3. Add garlic, mushrooms, thyme, and sage. Cook for 3–4 minutes until fragrant.
  4. Pour in the remaining 1/2 cup of wine, broth, Worcestershire sauce, bay leaves, salt, and pepper. Bring to a simmer for 10 minutes.
  5. Stir in heavy cream and simmer for an additional 5–10 minutes. Remove bay leaves and adjust seasoning.
  6. Preheat oven to 400°F. Toast bread slices until dry, about 10–15 minutes.
  7. Ladle soup into oven-safe bowls. Top each with a slice of bread and a generous amount of cheese.
  8. Broil 3–5 minutes until cheese is bubbly and golden. Serve hot.

Notes

  • Use apple cider or apple juice as a wine substitute if needed.
  • Vegetable broth makes this dish vegetarian.
  • Gruyère is the traditional cheese, but Swiss or mozzarella can be used.
  • Soup base can be made ahead and stored in fridge or freezer.
  • If oven-safe bowls are unavailable, broil cheese on bread separately.
