# Expert Tips:

01 -
  • The way the sweetness of caramelized onions plays with spicy heat creates layers of flavor you usually only find in restaurants
  • It comes together in under an hour but tastes like something that simmered all afternoon
  • That moment when the honey hits the hot pan and everything suddenly smells like caramel and comfort
02 -
  • Caramelizing onions cannot be rushed and high heat will only burn them, so embrace the low and slow approach
  • The sauce will look thin at first but thickens quickly as it coats the hot pasta
  • Room temperature cream prevents it from separating when it hits the hot pan
03 -
  • Slice your onions as uniformly as possible so they caramelize at the same rate
  • Use a wide skillet instead of a deep pan to help the moisture evaporate more efficiently
