CHICKEN TETRAZZINI (BY GIADA DE LAURENTIS)

Steps:

• 1. Preheat the oven to 450 degrees F.
• 2. Spread 1 tablespoon of butter over a 9 x 13 inch baking dish. Melt 1 tablespoon each of butter and oil in a deep large nonstick frying pan over medium-high heat. Sprinkle the chicken with salt and pepper. Add the chicken to the hot pan and cook until pale golden and just cooked through, about 4 minutes per side. Transfer the chicken to a plate to cool slightly. Coarsely shred the chicken into bite-size pieces and into a large bowl.
• 3. Meanwhile, add 1 tablespoon each of butter and oil to the same pan. Add the mushrooms and saute over medium-high heat until the liquid from the mushrooms evaporates and the mushrooms become pale golden, about 1-2 minutes. Add the onion, garlic, and thyme, and saute until the onion is soft. Add the wine and simmer until it evaporates, about 2 minutes. Transfer the mushroom mixture to the bowl with the chicken.
• 4. Melt 3 more tablespoons butter in the same pan over medium-low heat. Add the flour and whisk for 2 minutes. Whisk in the milk, cream, broth, nutmeg, remaining 1 3/4 teaspoons salt, and remaining 3/4 teaspoon pepper. Increase the heat to high. Cover and bring to a boil. Simmer, uncovered, until the sauce thickens slightly, whisking often, about 10 minutes.
• 5. Bring a large pot of salted water to a boil. Add the linguine and cook until it is tender but still firm to the bite, stirring occasionally, about 9 minutes. Drain. Add the linguine, sauce, peas, and parsley to the chicken mixture. Toss until the sauce coats the pasta and the mixture is well blended.
• 6. Transfer the pasta mixture to the prepared baking dish. Stir the cheese and breadcrumbs in a small bowl to blend. Sprinkle the cheese mixture over the pasta. Dot with the remaining 3 tablespoons of butter. Bake, uncovered, until golden brown on top and the sauce bubbles, about 25 minutes.
