# Expert Tips:

01 -
  • It transforms basic leftovers into something that feels like a special occasion dinner without requiring more than 20 minutes of active effort
  • The creamy pesto sauce clings to every piece of pasta and chicken, ensuring no boring bites in the entire dish
02 -
  • Undercooking the pasta initially is crucial because it will absorb liquid and continue cooking in the oven
  • The sauce will look thinner than you expect before baking, but it thickens beautifully in the oven
03 -
  • Use half-and-half instead of heavy cream for a slightly lighter version that still feels indulgent
  • Let the dish rest for the full 5 minutes so portions hold their shape better when serving
