Cut the chicken into bite-sized pieces.
Add all the spices and olive oil. Mix to blend and set aside.
Heat a pot at high height and melt 1 tablespoon of the butter.
Cook the chicken in batches allowing it to brown on all sides.
Flip the chicken until all sides change color. And cook until the chicken is cooked to 165° Celsius.
Once all the chicken is cooked remove it to another bowl.
Add the rest of the butter into the pot. Toss in the crushed garlic. Saute over medium heat for 2 minutes or until garlic turns light brown.
Add the flour. Switch to a whisk. And cook off the raw flour taste for 1-2 minutes.
Add the milk in half a cup increments, mixing until you obtain a homogenous mixture.
Once you've added all the milk, also add salt and pepper to taste.
Also, add the grated nutmeg for flavor.
Cook over medium heat for 10 minutes, while continuously mixing, until the sauce coats the back of a spoon.
Meanwhile cook the pasta to al-dente, as per instructions on the package.
Take the sauce off the heat and add two tablespoons of parmesan cheese and the seasoned chicken. Mix to combine.
Combine with drained pasta together with a ¼-½ cup pasta water, depending on how thick your pasta sauce is.
Serve with black pepper and additional grated parmesan cheese. Enjoy!
