Ingredients

  • 1 pound (450 g) egg noodles uncooked
  • 2 cups (280 g) cooked chicken cubed or shredded
  • 1 cup (140 g) thick sliced deli ham or turkey cubed
  • 1 cup (120 g) swiss cheese shredded

For the cheese sauce:

  • 4 tablespoons (56 g) butter
  • 2 cloves garlic minced
  • 4 tablespoons (32 g) all purpose flour
  • 2 cups (480 ml) whole milk or 2%
  • 2 teaspoons dijon mustard
  • ¼ teaspoon ground pepper
  • ¼ cup (22 g) grated parmesan cheese
  • 1 cup (120 g) swiss cheese shredded

For the topping:

  • ¾ cup (45 g) panko breadrcumbs
  • ¼ cup (22 g) grated parmesan
  • 2 tablespoons (28 g) butter melted

Instructions

  • Preheat the oven to 350°F/180°C, and lightly spray a 9x13 inch pan with non stick spray.
  • In salted water cook egg noodles until al dente according to package directions, drain and set aside.
  • As the pasta is being cooked, make the cheese sauce. Melt butter in a saucepan, add garlic and cook for 30 seconds, then add the flour and stir and cook for 1 more minute.
  • Slowly add the milk while whisking, then add the dijon mustard and pepper and whisk again.
  • Add the parmesan and swiss cheese, and whisk until melted and smooth.
  • To the prepared 9x13 pan, add the cooked noodles, cheese, chicken and ham, and give everything a quick stir. Then pour the cheese sauce on top.
  • Make the topping, in a small bowl combine breadcrumbs with parmesan and butter.
  • Top the casserole filling with the topping, and bake for 25-30 minutes.

Notes

  • Choose the right size dish. I suggest a 9x13-inch dish for this recipe. If your dish is too small, the creamy sauce can bubble over and a larger dish might cause your casserole to dry out. If you are going to use a different-sized dish, adjust the amounts accordingly.
  • Don’t overcook the noodles. Cook the noodles only until they’re al dente. If you overcook them, they could turn mushy when the casserole is baking in the oven.
  • Shred the cheese yourself. While using bags of pre-shredded cheese is convenient, the cheese doesn’t melt very well due to the anti-caking agent they use to prevent the cheese from sticking together in the bag. It’s better to buy a block of cheese and shred your own at home.
  • Let it rest. It’s much easier to slice your casserole if you let it sit for a few minutes before serving.
