# Expert Advice:

01 -
  • The creamy sauce comes together faster than you think, and the way Monterey Jack melts creates these incredible cheese pulls that make everyone at the table smile
  • Its one of those rare dishes that actually tastes better the next day, so leftovers become something you look forward to instead of dread
02 -
  • The sauce might look thin when you first combine it with the pasta, but it thickens beautifully in the oven, so trust the process
  • Adding sour cream while the sauce is too hot will cause it to separate, so always remove the pan from heat first
03 -
  • Shred your cheese from blocks instead of buying pre-shredded bags, because the anti-caking agents in pre-shredded cheese prevent it from melting into that silky smooth consistency
  • Grate your onions and bell peppers extra small if you are cooking for picky eaters who claim they do not like vegetables
