How to Make Creamy Mushroom Roasted Onion Soup

  1. Preheat oven to 400°F (200°C).
  2. Peel one large onion, leaving it whole. Rub with 1 tablespoon olive oil, salt, and pepper. Wrap in foil.
  3. Roast for 1 hour, or until softened and caramelized. Remove and cool completely.
  4. Meanwhile, chop the remaining onion.
  5. Heat remaining olive oil in a heavy-bottomed saucepan over medium heat.
  6. Add chopped onion, carrot, and celery; cook until softened (8-10 minutes).
  7. Stir in garlic, shallots, and mushrooms; cook 5 minutes, stirring frequently.
  8. Reserve 1 mushroom for garnish.
  9. Add white wine, scraping up browned bits from the pan.
  10. Stir in thyme and bring to a gentle simmer.
  11. Cook until mushrooms are tender (5-6 minutes).
  12. Stir in vegetable stock and simmer until reduced by half (10 minutes).
  13. Remove from heat and puree using an immersion blender (or in batches in a regular blender).
  14. Return soup to low heat; stir in cream.
  15. Season generously with salt and pepper.
  16. Chop the roasted onion into ¼-inch pieces and stir into the soup.
  17. Adjust seasoning as needed.
  18. Slice the reserved mushroom into 8 very thin lengthwise slices.
  19. Ladle soup into warmed bowls.
  20. Garnish with shaved Parmigiano-Reggiano, ¼ teaspoon chives, and a mushroom slice.
  21. Serve immediately with crusty bread and a glass of Chardonnay.
