Uniflasy’s 17×13-inch griddle is a straightforward tool for transforming your grill into a flat-top station. It’s a simple, effective rectangle of cast iron that fits over most standard grill grates. The value here is in its versatility—you can sear burgers on one half while cooking pancakes on the other, all without flare-ups.

The cast iron construction is the key to its performance. It heats evenly and holds that heat steadily, which is crucial for a good sear on steaks or consistent cooking for a full breakfast. The factory-applied nonstick coating makes initial use and cleanup easier, though it requires careful hand-washing to preserve it. At 17 by 13 inches, the surface area is generous enough for a family meal but compact enough to fit universally on gas, charcoal, or electric grills from brands like Weber and Char-Broil.

This griddle does add significant weight to your grill and, like all cast iron, requires a brief preheat to perform its best. It’s a single-purpose insert, but it executes that purpose reliably. You get a dedicated cooking zone for everything that would fall through your regular grates.
