# Expert Advice:

01 -
  • The vegetables roast into silky ribbons—each forkful is like a little mosaic of flavor tucked inside your meal.
  • This is the dependable dish I can serve hot or cold, fancy or casual, and it’s never failed to impress myself or surprise my friends.
02 -
  • If you slice the vegetables too thick, you'll end up with a crunchy tian instead of a melt-in-your-mouth one—learned that the first time I rushed the prep.
  • Letting the dish rest for 10 minutes before serving lets everything settle and prevents slices from slumping apart.
03 -
  • Slicing is everything—a sharp knife or mandoline means no stubborn bite and perfectly melded veggies.
  • Letting the vegetables overlap tightly keeps them moist and prevents the dish from drying out during baking.
