准备

• Position a rack in the center of the oven and heat to 450°F. Generously butter a large rimmed baking sheet.
• 将一大锅盐水煮沸。
• Meanwhile, in a medium bowl, vigorously whisk the milk, flour, mustard, thyme, 1-1/2 tsp. salt, and 1/2 tsp. pepper. Stir in about two-thirds of the cheddar.
• 把意大利面煮5分钟,然后加入兄弟ccoli. Continue cooking until the pasta is al dente and the broccoli is just tender, 1 to 2 minutes more.
• 排干面食和西兰花，然后将它们返回到锅中。加入鸡肉，牛奶和切达干酪混合物，然后轻轻折腾。转移到准备好的烤盘上，均匀散布。将havarti撕成碎片，然后将其顶部面食。撒上剩余的磨碎的切达干酪。烘烤大约20分钟的金黄色和气泡。立即服务。
