We took every measure to max out the mushroom factor in this soup, then added blue cheese toasts for a salty, cheesy garnish.

- Yield: 6 cups
- Difficulty: Easy
- Total: 1 hr
- Active: 5 mins
- 2 tablespoons unsalted butter (1/4 stick)
- 1 cup coarsely chopped yellow onion
- 1/4 cup dry sherry
- 2 medium garlic cloves, thinly sliced
- 4 fresh thyme sprigs, leaves removed
- 2 pounds white mushrooms, sliced (about 12 cups)
- 4 cups mushroom broth or water
- 3/4 cup heavy cream
- 2 teaspoons freshly squeezed lemon juice
- 10 to 15 thin baguette slices
- 3 ounces blue cheese, crumbled (about 2/3 cup)
- Melt butter in a large saucepan over medium heat. When foaming subsides, add onion, season with salt, and cook, stirring occasionally, until soft and translucent, about 5 minutes.
- Add sherry and cook until alcohol smell has dissipated, about 1 to 2 minutes. Add garlic, thyme leaves, and mushrooms and cook, stirring occasionally, until mushrooms are shrunken and nearly covered in liquid, about 20 minutes. Add broth or water and cook until flavors have melted, about 30 minutes.
- Process soup in a blender until smooth (you may have to do these in batches), then return to the pot over low heat. Add cream and bring to a simmer. Add lemon juice and season to taste with salt and freshly ground black pepper.
- Heat the broiler, top baguette slices with 1 to 2 teaspoons blue cheese each, and place on a baking sheet. Broil until cheese is bubbly and toast is crisp, about 1 to 2 minutes. Float 2 to 3 toasts in each bowl and serve.
