03 - Season with salt, pepper, and red pepper flakes if desired. Bring to a boil, then reduce to a simmer.

# Expert Suggestions:

01 -
  • All the flavors soak into the pasta as it cooks so every bite tastes intentional.
  • It rescues you from extra dishes and delivers incredible comfort in half an hour.
02 -
  • Stir the pasta often as it cooks—if you forget, it loves to stick or clump, and you'll lose that lovely creamy texture.
  • Adding the cream and cheese too early will make everything grainy instead of smooth; timing really is everything.
03 -
  • Cut the basil only right before adding to keep its flavor bright—never ahead of time.
  • Finish the pasta as soon as it’s al dente, even if there’s a little extra sauce; it will thicken as it cools.
