Ingredients

  • 5 1/2 tablespoons butter
  • 3/4 cup panko breadcrumbs or 3/4 cup plain breadcrumbs
  • 1/2 cup grated parmigiano-reggiano cheese, divided
  • 1/4 cup all-purpose flour, plus
  • 2 tablespoons all-purpose flour
  • 3 1/2 cups whole milk
  • 1/4 teaspoon ground nutmeg
  • kosher salt
  • fresh ground black pepper
  • 1 1/2 cups grated gruyere cheese
  • 1 1/2 cups grated imported swiss cheese (Comte is best)
  • 1 1/2 cups grated Fontina cheese (Italian Fontina, not Danish)
  • 3/4 lb penne pasta

Method

  • Preheat the oven to 350°. Meanwhile, bring 2 qts water to a boil in a 3 qt pot.
  • In a small pan, melt 2 1/2 tbsp butter. Add the panko and half the Parmigiano. Toss well to coat and set aside.
  • Melt the remaining butter in a medium saucepan. Add the flour and whisk constantly for 5 minutes; do not allow it to brown. Still whisking, add the milk and nutmeg. Cook another 5 minutes. Add the remaining Parmigiano, all of the Gruyere, 1 cup of Comte and 1 cup of Fontina. Continue whisking until the cheese is fully melted and incorporated. Pour the cheese sauce into a large bowl.
  • Add 1 tbsp salt to the boiling water, along with the pasta. Cook until al dente, about 8 minutes. Drain well in a colander, then add the pasta to the cheese sauce. Season with salt and pepper to taste.
  • Pour cheesy pasta into a 10x12" baking dish. Top with remaining Comte and Fontina, then sprinkle buttered bread crumbs over the top. Bake 30 minutes until golden brown and bubbly.
