Caramelized Onions

Cheese Base

Method

Caramelized Onions

  1. 1

    Heat olive oil in a skillet over medium heat.

  2. 2

    Add sliced onions and a pinch of salt and sugar to help with caramelization.

  3. 3

    Cook slowly over medium-low heat, stirring occasionally, for 25–30 minutes until deep golden brown and sweet. Set aside.

Wild Mushrooms

  1. 4

    Heat olive oil in a large skillet over medium-high heat.

  2. 5

    Add sliced wild mushrooms and cook without moving them too much for the first few minutes to allow browning.

  3. 6

    Add minced garlic, salt, black pepper, and chili flakes. Stir and cook for another 5–7 minutes until mushrooms are tender and golden. Set aside.

Cheese Base

  1. 7

    In a small bowl, mix the Boursin cheese with shredded Fontina until well combined and spreadable. Bring to room temperature if needed for easier mixing.

Bread & Assembly

  1. 8

    Preheat oven to 375°F (190°C) or heat a grill pan.

  2. 9

    Brush both sides of the bread slices lightly with olive oil.

  3. 10

    Toast the bread in the oven or on a grill pan until golden and crisp, about 3–5 minutes per side.

  4. 11

    Spread a generous layer of the cheese mixture over each slice of toasted bread.

  5. 12

    Top with a layer of caramelized onions, followed by sautéed wild mushrooms.

  6. 13

    Drizzle each toast with a small amount of truffle oil.

  7. 14

    Garnish with chiffonade of fresh basil and a pinch more chili flakes if desired.

  8. 15

    Serve warm.
