Instructions

Step 1

In a large saucepan, heat 4 tablespoons olive oil over medium-high. Add the onions and fennel and cook, stirring, until soft and caramelized, about 1 hour. Add the garlic and cook, stirring, until fragrant, 2 minutes. Pour in the stock and bring to a simmer over medium heat.

Step 2

Meanwhile, in a 12-inch skillet, heat the remaining 1 tablespoon olive oil over medium-high. Add the mushrooms and cook, stirring, until golden, about 5 minutes. Add the wine and cook until slightly reduced, about 5 minutes. Scrape the mushrooms and wine into the soup and cook, stirring, to marry flavors, about 5 minutes. Season the soup with salt and pepper, ladle into bowls, and garnish with the reserved fennel fronds.
