Equipment

  • Medium saucepan
  • Baking dish (8x8 or similar)
  • Sharp knife
  • large skillet
  • spatula
  • sheet pan
  • parchment paper

Ingredients
  

For the Polenta:

  • 2 cups vegetable broth
  • 1 cup polenta coarse cornmeal
  • 1 cup grated Pecorino Romano
  • 1 tablespoon unsalted butter
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 tablespoons olive oil divided

Mushroom Topping:

  • 2 cups mixed wild mushrooms chopped (like cremini, shiitake, and oyster)
  • 1 tablespoon unsalted butter
  • 1 tablespoon olive oil
  • 2 cloves garlic minced
  • 1 tablespoon fresh thyme leaves
  • 1/4 cup dry sherry or Marsala wine
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • Grated Pecorino Romano for garnish
  • Fresh parsley chopped, for garnish

Instructions
 

Prepare the Polenta:

  • Bring the vegetable broth to a boil in a medium saucepan. Gradually whisk in the polenta to avoid lumps.
  • Reduce the heat to low and cook, stirring frequently, for 10-12 minutes until thickened.
  • Stir in the Pecorino Romano, 1 tablespoon unsalted butter, 1 teaspoon salt, and 1/2 teaspoon black pepper.
  • Pour the polenta into a parchment-lined baking dish, spreading it evenly. Let cool to room temperature, then refrigerate for 1-2 hours or until firm.

Cut and Fry the Polenta Bites:

  • Once set, remove polenta from the dish and cut into 1-inch squares.
  • Heat 1 tablespoon olive oil in a large skillet over medium-high heat.
  • Fry the polenta squares in batches for 2-3 minutes per side until golden and crispy.
  • Transfer the polenta bites to a parchment-lined baking sheet and keep warm in a low oven.

Sauté the Mushrooms:

  • In the same skillet, heat 1 tablespoon unsalted butter and 1 tablespoon olive oil over medium heat. Add the garlic and cook for 1 minute until fragrant.
  • Add the mushrooms and thyme, cooking until softened and slightly browned, about 5-7 minutes.
  • Pour in the sherry or Marsala wine and cook until evaporated, about 2 minutes.
  • Season with 1/2 teaspoon salt and 1/2 teaspoon black pepper.

Assemble the Bites:

  • Top each polenta bite with a spoonful of the mushroom mixture. Sprinkle with a little more Pecorino Romano and fresh parsley. Serve warm with a drizzle of olive oil if desired.

Notes

Expert Tips from My Kitchen:

  • Chill Completely: Let the polenta fully set before slicing. If you try to cut too early, the slices may fall apart.
  • Crisp is Key: Whether pan-fried or cooked in the air fryer, don’t crowd the pan. You want golden brown edges, not steamed bites.
  • Make Ahead: You can pour polenta into the dish and chill it the day before. The mushroom topping can also be made in advance and reheated in a small saucepan before serving.
  • Optional Toppings: Try finishing with toasted pine nuts, whipped goat cheese, or even a hint of maple syrup for a sweet-salty contrast.

Serving Suggestions

  • On a Board: Serve on a platter with rosemary sprigs or thyme for a rustic, festive look.
  • With a Dip: Pair with truffle aioli, whipped goat cheese, or spicy garlic chili oil for extra flavor and texture.
  • Cocktail Pairings: Serve with a glass of red wine, prosecco, or even something playful like a Key Lime Pie Toast for a fun twist on dessert cocktails.

Storage Notes

  • Fridge: Store leftovers in an airtight container in the refrigerator for up to 3 days.
  • Reheat: Re-crisp in a hot skillet, preheated oven, or air fryer. The microwave is fine in a pinch but will soften the texture.
  • Make Ahead: Cook the polenta base and prep the mushroom topping ahead of time. Assemble just before serving to keep the texture right.
