Any leftover pasta tossed in the cheese sauce can be reheated in an oven-safe dish, covered with aluminum foil. Add in some leftover vegetables from the previous night, and an extra Tbsp of whole milk and butter, and throw the mix in the oven at 350F for 30 minutes. All of a sudden you have yourself a fine dinner casserole made only with leftovers!
Some people won’t include the rind in sauce recipes when using these soft creamy cheeses like Camenbert or Brie. I personally have no problem with it, and quite enjoy the textural qualities of the warm rind in the cooked pasta.
