How to Make Beautiful Baked French Onion And Mushroom Soup

  1. Preheat oven to 375°F (190°C).
  2. Halve 2 large yellow onions lengthwise and thinly slice into half-moons.
  3. Heat 2 tablespoons of olive oil in a large pot or Dutch oven over medium-low heat.
  4. Add the onions and sprinkle with 1 teaspoon of salt.
  5. Cover and cook, stirring occasionally, for 30 minutes, or until onions are softened and caramelized.
  6. While onions cook, thinly slice 8 ounces of cremini mushrooms, mince 2 cloves of garlic.
  7. In a separate bowl, whisk together ½ cup dry sherry, 2 tablespoons balsamic vinegar, 1 tablespoon Worcestershire sauce, 4 cups beef broth, 1 bay leaf, and ½ teaspoon black pepper.
  8. Once onions are caramelized, add the mushrooms and garlic to the pot. Cook for 5 minutes, stirring occasionally.
  9. Pour the sherry mixture into the pot. Bring to a boil, then reduce heat and simmer for at least 1 hour, or until flavors meld.
  10. Remove the bay leaf.
  11. Prepare 4 oven-safe bowls. Place each bowl face-down on a sheet of pie crust.
  12. Cut out 4 circles of pie crust, slightly larger than the bowls (about 1 inch bigger).
  13. Carefully remove the bowls, leaving the crust circles on the baking sheet.
  14. Ladle the soup evenly into the prepared bowls.
  15. Place a crust circle on top of each bowl, ensuring it doesn't touch the soup.
  16. Poke a small hole in the center of each crust to vent.
  17. Bake for 12 minutes, or until the crust is golden brown.
  18. Remove from oven and evenly sprinkle 1 cup of grated Swiss cheese over each crust.
  19. Return to the oven for 3-5 minutes, or until the cheese is melted and bubbly.
  20. Serve immediately and watch your guests' delight as they break through the cheesy crust!

Chef's Tip for Extra Flavor

Want to unlock deeper, more complex flavors? Try toasting your whole spices before grinding them, or blooming ground spices in a little warm oil to enhance their aroma. Deglazing your pan with a bit of stock, wine, or even water after browning ingredients can capture those tasty caramelized bits, adding richness to your dish.
