POLENTA SQUARES WITH MUSHROOM RAGU

Steps:

• Bring the water, 1 tablespoon butter, and 1/2 teaspoon salt to a boil in a heavy medium saucepan. Gradually whisk in the polenta. Reduce the heat to medium-low. Stir constantly until the polenta thickens, about 5 minutes. Pour the polenta into a greased 9 by 9-inch baking pan, spreading so that it is 1/3-inch thick. Cover and let stand at room temperature until set, about 15 minutes.
• Meanwhile, heat the oil in a heavy large frying pan over medium-high heat. Add the mushrooms and onion. Sprinkle with 1/2 teaspoon of salt and 1/4 teaspoon of pepper and saute until the juices evaporate, about 8 minutes. Add the garlic and saute until the mushrooms are golden brown, about 2 minutes longer. Decrease the heat to medium-low. Add the Marsala. Cover and simmer until the Marsala has reduced by about half, about 5 minutes. Stir the flour and remaining 2 tablespoons of butter in a small bowl to form a paste, then stir the paste into the mushroom mixture. Cover and simmer until the sauce thickens slightly, about 2 minutes. Remove from the heat. Stir the parsley into the ragu. Season the ragu, to taste, with more salt and pepper.
• Cut the polenta into 36 bite-size squares. Arrange the polenta squares on a platter. Spoon the warm ragu atop the polenta and serve immediately.

ROASTED MUSHROOM POLENTA BAKE

Steps:

• Heat the oven to 400ºF.
• Trim off and discard any tough stems from the mushrooms (such as those from shiitakes). Cut or tear the caps into roughly 1-inch pieces. Arrange the mushrooms on a baking sheet (parchment-lined for easy clean-up). Drizzle with the 2 tablespoons olive oil, vinegar, and salt and pepper to taste. (I use a teaspoon of Diamond Crystal kosher salt for a pound of mushrooms.) Toss to combine, then spread into an even layer. Transfer pan to the oven and cook for 15 to 20 minutes or until done to your liking. Remove pan from the oven and lower the oven temperature to 375ºF.
• Meanwhile, prepare the polenta: In a large, wide, shallow oven-safe skillet, bring 5 cups of water to a simmer. While whisking constantly, slowly pour the polenta into the water in a steady stream. Whisk for a couple of minutes or until the polenta is incorporated. Turn the heat to the lowest setting. Add a teaspoon of kosher salt. (I use 2 teaspoons of kosher salt, but I love salt, so add to taste.) Simmer for 15 to 20 minutes or until the polenta is thick and the grains are tender. Stir in the 2 tablespoons of olive oil. Taste, being careful to let the polenta cool before you do so. Adjust with more salt and pepper to taste. (I add a sprinkling of sea salt at this point.)
• Remove the polenta from the heat. Spread the mushrooms in an even layer over the polenta. Sprinkle the thyme over top. Season with pepper to taste. At this point, if you wish, you can sprinkle the parmesan over top. (See notes above if you wish to use cream instead or omit the cheese altogether.)
• Transfer pan to the oven and bake for 15 minutes or until bubbling at the edges. Shave more parmesan over top if you wish. Serve immediately, passing salt, pepper, and more parmesan on the side. I like drizzling my bowl with a little bit more olive oil, too.

BAKED MUSHROOM CHICKEN

Steps:

• Flatten each chicken breast half to 1/4-in. thickness. Place flour in a shallow bowl. Dip chicken in flour to coat both sides; shake off excess. , In a large skillet, brown chicken in 2 tablespoons butter on both sides. Transfer to a greased 11x7-in. baking dish. In the same skillet, saute mushrooms in the remaining butter until tender. Add the broth, salt and pepper. Bring to a boil; cook until liquid is reduced to 1/2 cup, about 5 minutes. Spoon over chicken., Bake, uncovered, at 375° until chicken is no longer pink, about 15 minutes. Sprinkle with cheeses and green onions. Bake until cheese is melted, about 5 minutes longer.
