Instructions
- Step 1: Bring 4 cups water and 1 teaspoon salt to a boil in a medium saucepan. Gradually whisk in 1 cup polenta, reducing heat to low. Cook, stirring frequently, for 25-30 minutes until thick and creamy.
- Step 2: While polenta cooks, preheat oven to 400°F. Toss 12 ounces sliced mixed mushrooms with 2 tablespoons olive oil, 3 minced garlic cloves, 1 tablespoon chopped fresh thyme, and 1/2 teaspoon black pepper. Spread on a baking sheet and roast for 15-20 minutes until tender and caramelized.
- Step 3: When polenta is done, stir in 1/2 cup grated Parmesan cheese and 1 tablespoon olive oil for creaminess. Pour the polenta into a greased 9-inch round cake pan, smoothing the top.
- Step 4: Let the polenta cool slightly to set, about 10 minutes, then top evenly with the roasted mushrooms.
- Step 5: Garnish with additional grated Parmesan before slicing into wedges and serving warm.
