Ingredients

Instructions

  1. Step 1: Bring 4 cups water and 1 tsp salt to a boil in a medium saucepan. Gradually whisk in 1 cup polenta and reduce heat to low, stirring constantly for 20 minutes until thick and creamy.
  2. Step 2: Remove from heat and stir in 3 tbsp butter and 1/2 cup grated Parmesan cheese until fully incorporated and silky.

  6. Step 6: Pour in 1/4 cup dry white wine and cook for another 3 minutes until the liquid reduces by half. Season with 1/2 tsp black pepper.
  7. Step 7: Spoon the mushroom mixture evenly over the polenta and bake uncovered for 25 minutes until the edges are golden and the topping is bubbling.
