Scale
FLATBREAD BASE
- 1 ball of prepared flatbread dough (store-bought or use my Italian Flatbread Dough with 00 Flour Recipe)
- 1 tablespoon extra virgin olive oil, for brushing
TOPPING
- 1 1/2 cups wild mushrooms (shittake, cremini, oyster), sliced
- 1 small yellow onion, thinly sliced
- 1 tablespoon butter
- 1 tablespoon extra virgin olive oil
- 1 teaspoon fresh thyme (and rosemary if desired)
- 1 1/2 cups fontina cheese, freshly shredded
- 1 tablespoon white truffle oil, for finishing
- flaky sea salt
- cracked pepper
- optional garnish : microgreens or arugula
Instructions
- Caramelize the Onions : Heat butter and olive oil in a skillet over medium heat. Cook onions slowly (20 – 25 minutes), stirring occasionally until golden brown and soft. Set aside.
- Sauté the Mushrooms : In the same pan, add a touch more oil if needed. Cook mushrooms 6 – 8 minutes until browned and moisture has evaporated. Add herbs, salt, and pepper. Remove from heat.
- Prepare the Crust : Preheat oven to 450°. Roll or stretch dough into a 12-inch round or rectangle. Place on parchment-lined baking sheet or pizza stone and brush with olive oil.
- Assemble : Spread caramelized onions evenly over crust. Add sautéed mushrooms and top with shredded fontina.
- Bake : Bake 10 – 13 minutes, until crust is golden and cheese is melted and bubbling.
- Finish : Drizzle lightly with truffle oil, sprinkle with flaky sea salt, and garnish with microgreens or arugula if desired.
- Serve : Slice and enjoy immediately while warm and crisp.
