Begin by grating all the cheese and setting it aside.
Cook your pasta according to the package instructions and season the pasta water with salt, be generous!
In a large saucepan, melt the butter and once melted add in the flour and whisk until a paste-like consistency forms and the butter and flour have fully combined.
Gradually whisk in ¾ of the milk, keep whisking until the sauce begins to thicken. You may or may not need all the milk. Reserve a splash or two of milk to add into the sauce later.
Gradually stir in the grated cheese. Make sure that this is done in stages and do not add all the cheese at once. Reserve a handful and a half of each cheese to use to sprinkle on top of the Mac and cheese before baking.
Add your seasonings to your cheese sauce and stir well keeping the heat on low. Once combined turn off the heat.
Preheat the oven to 200° on the oven and grill setting.
Drain your cooked pasta and transfer it into your oven proof dish.
Add the cheese sauce to your cooked pasta and stir well. Top with the remaining grated cheese and bake in the oven until golden brown. This can take anywhere between 20 and 30 minutes make sure you check the Mac and cheese at the halfway point.
Remove from the oven and top with dried parsley, allow to stand for a minute or two before serving.
