6 servings


  • 4 ½ cups water

  • 1 ½ teaspoons salt, divided

  • 1 ½ cups coarse cornmeal

  • 3 tablespoons olive oil, divided

  • ¾ teaspoon dried sage, divided

  • 7 tablespoons grated Parmesan cheese, divided

  • 2 tablespoons salted butter

  • ½ pound fresh mushrooms, thinly sliced

  • ¼ teaspoon ground black pepper

  • 1 ½ cups grated Fontina cheese


  1. Preheat the oven to 350 degrees F (175 degrees C). Butter an 8x12-inch baking dish.

  2. Bring water and 1 teaspoon salt to a boil in a medium saucepan. Add cornmeal in a slow stream, whisking. Whisk in 1 tablespoon oil and ¼ teaspoon sage. Reduce the heat and simmer, stirring frequently with a wooden spoon, until very thick, about 20 minutes. Stir in 3 tablespoons Parmesan cheese.

  3. Meanwhile, melt 1 tablespoon butter with 1 tablespoon oil in a large frying pan over medium-high heat. Add 1/2 of the mushrooms, ¼ teaspoon of each of the salt and sage, and 1/8 teaspoon of the pepper. Cook, stirring frequently, until mushrooms are golden, about 5 minutes. Remove. Repeat with remaining mushrooms, 1 tablespoon each butter and oil, ¼ teaspoon salt and sage and 1/8 teaspoon black pepper.

  4. Pour 1/2 of the polenta into the prepared baking dish and spread in an even layer. Top with 1/2 of the mushrooms, followed by 1/2 of the Fontina cheese and 2 tablespoons Parmesan cheese. Repeat with remaining polenta, mushrooms, Fontina and Parmesan cheeses.

  5. Bake in the preheated oven until cheese is bubbling, about 15 minutes.
