I just did my first brisket on my 575 Pro last weekend and it turned out very well. I've used a water pan in the past when using a regular wood/charcoal smoker but didn't feel it was necessary with the Traeger. Like HouBBQ said, you could spray it if you want but I really don't think anything is necessary other than keeping the fat side up. The bark on this brisket was perfect, the meat tender and extremely moist. Still getting acquainted with my Traeger but I'm convinced that brisket is what these grills excel at.
