# Expert Advice:

01 -
  • One pan means you spend more time eating and less time scrubbing, which is basically the holy grail of weeknight cooking.
  • The chicken comes out impossibly tender while the peppers get just charred enough to taste like something special happened to them.
  • The spice blend tastes homemade and complex without requiring you to hunt down obscure ingredients.
02 -
  • Don't skip the single layer on the pan—I learned this the hard way when I tried to be efficient and stacked things, and ended up with steamed chicken instead of roasted, which is a completely different (and sadder) situation.
  • The lime juice at the end is what makes people say this tastes restaurant-quality; it's not the spices, it's that brightness that ties everything together.
03 -
  • Cut your chicken into uniform strips so everything cooks at the same speed—thick pieces will be overdone before thin ones catch up.
  • Don't be shy with the marinade; the more the chicken and vegetables are coated, the more flavor you get and the better the caramelization in the oven.
