# Expert Suggestions:

01 -
  • They roast hands-free while you focus on the rest of dinner.
  • The edges get crispy and caramelized without any stirring or watching.
  • Theyre versatile enough to serve alongside grilled chicken, tuck into sandwiches, or pile on top of roasted vegetables.
02 -
  • Flip the slices gently with a spatula so the rings stay intact, I learned this after turning a few into onion confetti.
  • If your onions are browning too fast on the edges, lower the oven to 375°F and add a few minutes to the roasting time.
03 -
  • Let the onions cool for a minute or two before serving, they hold their shape better and the flavor settles.
  • Save any broken rings and roast them anyway, they turn into crispy bits that are perfect for sprinkling over salads or pasta.
