Sheet pan cooking is pretty much the same as baking in a glass dish; both are frugal and nearly effortless. What is the difference...if there is any?
Sheet pan cooking/baking/roasting achieves a slightly different finish. That means, a sheet of chicken or steak with any vegetable will tend to sear in flavor and blacken more but can also lose flavorful juices. However, sheet pan cooking develops more crispiness on the outside.
Baking in a glass dish allows for less juice reduction from any meat/veggie. And, more opportunity to add larger amounts of liquid for sauce/gravy. Here are some past blog photos that you can search for in Brainy Archives to try either in a glass baking dish or on a sheet pan. Remember to coat either the pan or dish with olive oil before food choices and popping in the oven.
