Polenta Bites with Wild Mushrooms and Fontina

These polenta bites with wild mushrooms and fontina offer a sophisticated twist on vegetarian party food. Slices of prepared polenta are roasted until they develop a crisp exterior, providing the perfect base for a rich, earthy topping. The combination of meaty mushrooms, sharp shallots, and a splash of sherry vinegar creates a savoury depth that is beautifully balanced by the nutty, melted fontina cheese.

Ideal as a stylish starter or a moreish canapé, this dish is surprisingly simple to assemble for guests. You can even prepare the mushroom mixture a day in advance and store it in the fridge to save time. Simply reheat slightly before topping the roasted polenta to ensure a perfect, bubbling finish every time you serve.

Ingredients for Polenta Bites with Wild Mushrooms and Fontina

  • 1.8kg prepared polenta, sliced into 1/2-inch-thick rounds (about 30 rounds)

  • 2 tablespoons extra-virgin olive oil, plus more for brushing

  • 60g (1/2 stick) unsalted butter

  • 900g assorted wild mushrooms (such as oyster, crimini, and/or stemmed shiitake), cut into thick slices

  • 2 shallots, thinly sliced

  • 60ml Sherry vinegar

  • 1 3/4 teaspoons kosher salt

  • 1/2 teaspoons freshly ground black pepper

  • 1/2 teaspoons crushed red pepper flakes

  • 1/2 cup chopped parsley leaves

  • 110g Fontina cheese, coarsely grated (about 240ml )

Preheat oven to 232°C. Brush both sides of polenta slices very lightly with oil and arrange on 2 rimmed baking sheets. Roast polenta until lightly golden brown and warmed through, about 25 minutes.

Meanwhile, melt butter with remaining 2 tablespoons oil in large, deep skillet over medium-high heat. Add mushrooms and cook, stirring often, until tender and browned, about 12 minutes. Add shallots, vinegar, salt, black pepper, and red pepper and cook, stirring, until tender, about 5 minutes. Stir in parsley.

Divide mushroom mixture between baking sheets with polenta. Top with cheese. Continue to roast until cheese is melted, about 5 minutes.

Arrange polenta bites on a platter and serve.

Mushroom mixture can be made 1 day ahead. Transfer to an airtight container and chill.
