@miss_jwo we've adopted a layer of foil topped by a layer of parchment for all of our baking. The food doesn't stick to the parchment, and any oil/grease doesn't seep through the foil. The result are baking trays we almost never need to wash whatsoever. Often the foil is even reusable, too.

We also found and LOVE sheets of parchment, rather than a roll. They are the exact right size to fit inside our metal tray and, impossibly, cost less than rolls of parchment. A+, would recommend!
