Ingredients

  • 1 ½ pounds (680 g) chicken breasts
  • ½ teaspoon salt
  • ½ teaspoon ground black pepper
  • 1 tablespoon (15 ml) olive oil not extra virgin
  • 6 tablespoons (84 g) unsalted butter divided
  • 1 pound (450 g) linguine pasta
  • 1 pound (450 g) button mushrooms thickly sliced
  • 1 medium yellow onion finely chopped
  • 3 cloves garlic minced
  • ¼ cup (30 g) all-purpose flour
  • 2 cups (480 ml) chicken stock
  • 1 ½ cups (360 ml) half and half
  • 2 cups (240 g) shredded mozzarella cheese divided
  • ¼ cup (21 g) grated Parmesan cheese

Instructions

  • Season the chicken breasts with salt and pepper.
  • In a Dutch oven, melt 2 tablespoons of butter and add olive oil. Sear the chicken breasts until fully cooked (about 10 minutes), then remove them from the pot. Cut into bite-size pieces and set aside.
  • In a large pot of salted boiling water, cook the pasta according to the package instructions until al dente. Drain and set aside.
  • To the same Dutch oven where you cooked the chicken, add 4 tablespoons of butter and let it melt. Add the sliced mushrooms and cook until they start to brown (about 4 minutes)
  • Add the chopped onion and minced garlic, and cook until the onions are translucent (2-3 minutes).
  • Sprinkle the flour over the mushrooms and stir well, cooking for a minute.
  • Slowly add the chicken stock and half and half, stirring continuously to avoid lumps. Let the sauce thicken slightly.
  • Add 1 cup of shredded mozzarella and the Parmesan cheese. Stir until the cheese is melted and the sauce is smooth. Remove from heat, and season with salt and pepper to taste.
  • Return the cooked chicken and pasta to the Dutch oven and mix well to coat everything in the sauce.
  • Preheat your oven to 375°F (190°C), or 170°C if you have a fan oven. Transfer the mixture to a 9x13-inch baking dish. Top with the remaining 1 cup of shredded mozzarella.
  • Bake for 30 minutes or until the top is bubbling and golden. Allow to cool for a few minutes before serving.

Notes

  • Make this a one pot meal! Instead of transferring the past to a casserole dish, be sure to use an oven-safe dutch oven or a deep skillet to cook the sauce. Then just add the mozzarella and put the whole thing right in the oven to bake.
  • Take a shortcut: Use already cooked chicken such as leftovers or rotisserie chicken. You'll need about 3 cups of diced or shredded meat.
  • Don't overcook the pasta: Make sure to cook pasta al dente, as it will continue cooking in the oven during the baking process.
  • Save some pasta water: You may not need it, but it can be helpful to have a bit of the cooking water from the pasta, in case you need to thin out the sauce later.
  • Add-Ins: Try adding some vegetables to this dish! You can stir in frozen peas or blanched broccoli florets before baking.
  • To Store: Store leftover chicken tetrazzini in the refrigerator for up to 3 days. The baked casserole can also be frozen for up to three months. The texture of the sauce will change slightly after storing, but you can stir in a splash of water or milk to make it creamy again!
  • Make Ahead: Assemble the casserole but don’t bake it yet. Cover and store in the fridge for up to 2 days. When it's almost time for dinner, bake at 350°F for 20 minutes. This step will warm the ingredients to the temperature they would be if you had just cooked them. Then continue to bake at 375°F for 30 minutes or until bubbly and golden brown.
