Originally dubbed LAB Experiment 041224-A, this tasty casserole makes a great cold weather comfort dish. It takes a while to prepare so it is perfect for that cold day when you want to occupy yourself indoors while warming up the house and filling the air with wonderful aromas.

Ingredients

  • ~1 kg spaghetti squash

  • 946 ml of chicken stock

  • 3 cups of 2% milk

  • ½ cup of all-purpose flour

  • 454 grams (16 Oz) of Crimini mushrooms, thick sliced

  • 200 grams of smoked Bergeron or Gouda, grated

  • 400-500 grams of Mozzarella cheese, grated

  • ½ cup of grated parmesan cheese

  • 2 ¾ cups of dry farfalle

  • ~ ½ cup of salted butter

  • 3 thick slices of ham (~325 grams), slivered into 1 inch pieces

  • 2 medium sized onions, diced

  • 1 red bell pepper, diced

  • 1 tablespoon of cooking oil

  • 1 tablespoon of liquid chicken bouillon concentrate

  • 3 teaspoons of garlic, finely chopped

  • 1 teaspoon of dried thyme

  • 1 teaspoon of dried basil

  • ½ teaspoon of light soy sauce

  • ¼ - ½ teaspoon of ground black pepper

  • 1 Oz of dry white wine

  • 2 bay leaves

Preparation

Farfalle Prep

  • Boil the farfalle until it is al-dente, according to the package directions.  It is OK if the pasta is a bit firm as it will continue cooking a bit in the casserole.

  • Once the mushrooms are done, remove them from the pan and set them aside.



 

Spaghetti Squash Prep

Getting the thick peel of a spaghetti squash requires a bit of effort.  However, it’s worth it.

It is best if you do it on a large, stable cutting board.

 

  • Start by cutting the ends off.

    • Exercise caution when cutting into the squash to avoid serious injury.  This works best with a sharp knife.



  • Next, stand the squash up, hold it in place with one hand and cut the peel in downwards slices.  You can start the cut about ¾ of the way up the squash to avoid getting the knife too close to your fingers. 

    • This process is the most difficult part.

  •  Continue around the circumference of the squash and then flip it over or turn it on its side to cut the remaining peel off.

  • Trim off any remaining peel.




  • Cut the squash in half, lengthwise, and scrape out the seeds using an ice cream scoop or a tablespoon.



  • Cut the squash into pieces about 1” wide by 2” long, as depicted below.



 

Sauce Prep

  • Put ⅓ cup butter and 2 teaspoons of finely chopped garlic in a medium sized saucepot and set the stovetop temperature to medium.
