Author Notes

You're just one sheet pan, one piece of focaccia, and a whole lotta cheese away from this slab grilled cheese. We used cheddar because we like it's melt, but you can use other comparable cheeses. You can also make Saltie's Focaccia for this, or go store-bought in a pinch. One of the best things about this party showstopper is that you don't even need butter or oil to get it going—the focaccia provides the good stuff. —Food52
