CREAMY BAKED MACARONI AND CHEESE WITH KALE AND MUSHROOMS

Steps:

• Set an oven rack about 6 inches from the heat source and preheat the oven to 425 degrees F.
• Bring a large pot of salted water to a boil. Add the macaroni and cook until it is al dente, about 6 minutes. Strain, reserving 1 3/4 cups of the pasta water. Set aside.
• Heat a large saucepan over medium-high heat. Add 3 tablespoons of the olive oil and the shiitake mushrooms and cook, stirring constantly, until the mushrooms are lightly browned in spots and softened, 4 to 6 minutes. Lower the heat to medium and add the kale, garlic and 1/2 cup of water, scraping up any browned bits at the bottom of the pan with the back of a wooden spoon. Add 3/4 teaspoon salt and 1/4 teaspoon pepper and stir to combine. Cook until the kale is wilted but still crisp-tender, about 3 minutes. Remove the vegetables to a bowl and set aside.
• Carefully wipe out the saucepan (or give it a quick rinse if it is really dirty). Add the half-and-half and cayenne and bring to a simmer over medium heat. Cook until reduced to 1 1/2 cups, about 15 minutes. Add the cream cheese and stir until melted. Whisk in the Cheddar and Gruyere until all the cheese is melted and the sauce is smooth.
• Add the macaroni and reserved pasta water to the saucepan and stir to combine. (The mixture will look very loose, but the pasta will suck up a lot of the sauce as it bakes.) Gently fold in the reserved vegetables. Season to taste with additional salt if needed. Pour into a 13-by-9-inch baking dish. Toss the bread crumbs, remaining 1/4 cup olive oil and a large pinch of salt and pepper in a medium bowl and sprinkle evenly over the macaroni and cheese. Bake until the cheese is bubbly and the bread crumbs are lightly browned and crispy, about 10 minutes.
