When your guests arrive, simply take it out of oven to serve! For a special treat, allow the mac & cheese to cool for 5 minutes before drizzling with truffle oil.
Preheat the oven to 375°F & butter Donatella’s ramekins or baker.
Cook pasta according to instructions less two minutes.
Melt the butter in a large saucepan over medium-low heat. Add the onion & cook until softened. Sprinkle flour over the onion & stir constantly for 2 minutes. Add light cream, sprinkle thyme, salt & pepper to taste.
Increase heat & continue to stir. When liquid reaches a boil, reduce heat to low simmer for 10 minutes. Remove from heat, stir in pepper, nutmeg, & all cheeses until just melted. Stir in pasta & mix well.
Spoon mixture into ramekins or baker mounding slightly, bake for 15 minutes, until the cheese is quietly sizzling.
