Ingredients
Balsamic Onions
- 1 tablespoon extra-virgin olive oil
 - 4 oz red onion, thinly sliced
 - 3 cloves garlic, finely shaved into slivers
 - 2 teaspoons brown sugar
 - 6 tablespoons Balsamic Vinegar of Modena P.G.I.
 - 2 sprigs thyme
 
Mushrooms
- 1 1/2 lb assorted mushrooms, like cremini, oyster, forest nameko, trumpet, morels, chantarelles, or maitake
 - 1/2 teaspoon salt, or to taste
 - 1/4 cup crème fraîche (optional)
 - 1 bunch chives, sliced into 1/4-inch pieces
 - Freshly ground black pepper, to taste
 - 1 lb burrata
 - 6 thick slices rustic bread
 - Extra-virgin olive oil, as needed
 - Balsamic Vinegar of Modena P.G.I., as needed
 - Flaky sea salt, as needed
 - Freshly ground black pepper, as needed
 
Directions
- For the balsamic onions: Heat the oil in a sauté pan over medium heat. Add the onions and garlic and sauté until translucent, about 8 minutes. Add the sugar, vinegar, and thyme, and cook over medium heat until the onions are soft and the pan is dry. Discard the thyme stems, and set the onions aside.
 - For the mushrooms: Heat a large sauté pan over high heat. Add the mushrooms and salt. Wait until they have sputtered and jumped a bit, until they begin to release water and brown. Stir occasionally until they are well-browned.
 - Add the reserved balsamic onions and stir to combine. Add the crème fraîche, if using, and season to taste with salt and pepper. Keep warm.
 - Set the oven to broil. Brush both sides of the bread slices with olive oil, and toast under the broiler.
 - To serve, distribute the mushrooms over the slices of bread and top each with a generous scoop of burrata. Drizzle with oil and vinegar, and garnish with basil, salt, and pepper. Serve right away.
