Measure out 3 ounces of pasta of choice. For macaroni, this is about one cup. Add the pasta to a microwave safe bowl and combine with 8 ounces of water (about 1 cup and 2 tablespoons).
Microwave the pasta and water on high for 5 minutes. Remove the bowl and stir the noodles. There should still be a few tablespoons of water in the dish. This is important to be able to form a sauce without flour.
Add in the cheese and optionally either Boursin or cream cheese and seasonings. Stir until the cheese is mostly melted.
Microwave for another 2 minutes. Stir to combine and let sit for 1-2 minutes.
Optional Additions
To make this more "elegant", you can top this with some kind of crispy topping and additional cheese. Breadcrumbs work, but I prefer crispy onions. Top the crispy topping with more grated cheese and either broil or torch it until slightly browned.
