The cheese starts with a roux: a mixture of melted butter and all-purpose flour. Though margarine works, the sauce is less likely to separate if you use real butter.

What causes cheese to separate from cooked pasta?
Using uncooked pasta can cause two problems. The cheese sauce separates in the extensive time it takes for the pasta to become tender. And, in the absence of water, the pasta absorbs moisture from the sauce, increasing the likelihood of separation.
