For a richer flavor, use vegetable broth instead of water when making the polenta. Experiment with different types of mushrooms, such as shiitake or oyster mushrooms, for a unique flavor profile. Fresh sage can be used instead of dried sage. Use 1 teaspoon of chopped fresh sage for every ¼ teaspoon of dried sage. For a crispy top, broil the gratin for the last 2 minutes of baking, keeping a close eye to prevent burning.

Follow The Directions
01
StepPreheat the oven to 350 degrees F (175 degrees C). Butter an 8x12-inch baking dish. (5 minutes)
02
StepBring water and 1 teaspoon salt to a boil in a medium saucepan. Add cornmeal in a slow stream, whisking constantly to avoid lumps. Whisk in 1 tablespoon oil and ¼ teaspoon sage. Reduce the heat to low and simmer, stirring frequently with a wooden spoon, until very thick and the polenta pulls away from the sides of the pan. Stir in 3 tablespoons Parmesan cheese. (25 minutes)
03
StepMeanwhile, 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 brown and have released their moisture, about 5 minutes. Remove from pan and set aside. Repeat with remaining mushrooms, 1 tablespoon each butter and oil, ¼ teaspoon salt and sage and 1/8 teaspoon black pepper. (15 minutes)
04
StepPour 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. (10 minutes)
05
StepBake in the preheated oven until cheese is melted, bubbling, and lightly golden brown, about 15 minutes. Let stand for 5 minutes before serving. (20 minutes)
