These used to be available in every grocery store, but I haven't seen them in ages. Last year my only option was to buy online. I got mine from mybrands.com, but a quick google search on foil burner liners brings up a number of other options.

I found tons of them online, but none of them have a 6 inch hole for the large commercial style burners on my stove. They all have 3 and 4 inch holes...

Whatever you do, don't line your oven with foil. A number of people on this forum have ruined the interior of their oven by lining it with foil - the foil melts onto the oven surface and can't be removed.

Why bother? It's an open burner range. I have the bluestar and I wouldn't even think of lining it with foil. Food just falls through the grates onto the drip tray underneath. Splatters and grease just add to the patina of the cast iron top, seasoning it much like a cast iron skillet. The only thing I clean up after cooking on the range is the stainless steel rail on the front.
