Pre-heat the oven to 200 deg C (400 deg F) - spray a large 20 x 30 cm ( 9 x 12 inch) casserole dish with cooking oil
Boil the Pasta in salted water until al dente
Meanwhile fry the Bacon in a pan (if Bits are used, no oil is needed – if you use another type, just fry as you normally will, then chop into bite-sized pieces) Remove from pan and keep warm
By now the Pasta should almost be done – Use a 4 cup microwave container (I use a glass measuring jug) – melt the Butter/margarine in the microwave. Add the flour and stir well until a smooth paste forms
Add the Milk little by little, stir and scrape the bottom and sides to make sure all the butter, flour and milk are combined. Microwave on HIGH for 2 minutes, stir, make sure there are no lumps, repeat this same method twice more. Then, microwave, 1 minute at a time, stirring after every minute until you are satisfied with the thickness of the sauce. (6 – 8 minutes)
Stir in two cups of White Cheddar, in 3 - 4 batches - stirring after each addition, to the white sauce
Drain the Pasta and place in a large mixing bowl, add the Bacon and the Cheese sauce - mix until combined
Transfer the Pasta to the prepared casserole dish - sprinkle over the remaining one cup White Cheddar Cheese - bake 10 minutes or until cheese is bubbly and all melted
Remove from the oven and sprinkle with Parsley (if using)
Notes
For a quicker version - omit the baking and serve the retained cup of White Cheddar over the pasta once transferred to a serving plate
