Ingredients

  • 1 pound (450g) uncooked spaghetti pasta
  • 2 tablespoons frying oil
  • 1 pound (450g) mushrooms
  • 2 medium onions
  • 2 tablespoon butter
  • 4 cloves garlic
  • 1 teaspoon thyme
  • 1/4 cup flour
  • 1/2 cup dry white wine
  • 2 cups milk
  • 1 cup (240ml) heavy cream
  • 2 cups chicken broth
  • 1 teaspoon Dijon mustard
  • 2 teaspoons lemon juice
  • salt and pepper to taste
  • 1 pound (450g) cooked turkey meat
  • 1 cup (150g) peas
  • 2 cups (200g) shredded Swiss cheese
  • 1 cup (100g) shredded low-moisture mozzarella
  • 3 tablespoons (45g) butter
  • 1 1/2 cups (85g) Panko breadcrumbs
  • 1/2 cup (45g) parmesan cheese

Instructions

  • Cook the pasta: cook the pasta 1 minute shorter than the package instructions. Drain and set aside.
  • Preheat the oven to 375°F (190°C).
  • Make the mushroom sauce:
  • Cut the mushrooms into thick slices, dice the onions, finely chop the garlic with a knife.
  • Cook the mushrooms: Heat the oil in a large frying pan over medium-high/high heat. Add the mushrooms in an even layer and cook without stirring for 1-2 minutes letting the mushrooms at the bottom brown. Then start stirring - the mushrooms will release water. Stir them from time to time (not too often) for a couple of minutes or until all the water is evaporated. Spread them in an even layer and cook without stirring for 1-2 minutes letting the mushrooms brown again. The mushrooms should be brown (at least some of them) and still a little bit firm (not too soft). Transfer the mushrooms to a plate.
  • Reduce the heat to low and add onions, cook for 3-4 minutes or until soft. Add butter (2 tablespoons), garlic, and thyme. Cook for 30 seconds.
  • Whisk in the flour and cook for a minute.
  • Add wine and cook until almost evaporated.
  • Add broth, milk, heavy cream, Dijon mustard, and lemon juice (if your pan is not big enough you may need to transfer all the ingredients to a pot). Bring gently to a boil then cook for 2-3 minutes. Season to taste with salt and pepper. You may think that the sauce is too runny but it will all thicken in the oven.
  • Assemble the casserole: Add the sauce, cooked spaghetti, cooked turkey, peas, mozzarella cheese, and cooked mushrooms to a 9x13 inch (23x33cm) casserole dish. Check if the casserole needs more salt and pepper. Toss to combine.
  • Make the crunchy topping: melt the butter (3 tablespoons) in a small pot, add the breadcrumbs and stir to coat. Take the pot off the heat and stir in parmesan cheese.
  • Top the casserole with 2 cups of shredded Swiss cheese and crunchy topping.
  • Bake for about 25-30 minutes or until the topping is golden and the casserole is bubbling.
  • Let rest for 5 minutes then serve.
  • Enjoy!
