Blackstone 28" Original

The plate is the story

10-gauge rolled carbon steel is thicker than most griddle cooktops at this size, and plate thickness is the specification that determines thermal mass — how much heat the surface is holding when cold food lands on it.

That matters because this griddle’s heat density is only moderate: 34,000 BTU across 525 square inches is 64.8 BTU per square inch, below the Blackstone 36’s 78 and well below the Traeger Flatrock 2-Zone’s 76.9. The thick plate partly compensates — it has more stored heat to give before the surface drops — but it cannot put heat back faster than the burners deliver it.

In practice: excellent for everyday cooking, slightly slow to recover under a heavy load of cold food. If a hard smash-burger crust is your priority, the Traeger 2-Zone does it better with less surface.

Two zones, and where that runs out

Two independently controlled zones gives you a hot end and a moderate end. That is genuinely enough for the great majority of griddle cooking: sear, move across, finish and hold.

Where it runs out is multi-component cooking. Toasting buns while holding cooked patties while searing the next batch is three jobs and you have two zones. The Weber Slate 30 gives you three zones over essentially the same surface (540 square inches), which is the strongest argument against this griddle.

Why it still wins on practicality

Size. 525 square inches on a cart fits a normal patio, takes a cover you can buy anywhere, and does not become a storage problem. The 36 is 244 square inches larger and the difference in footprint is what people regret.

Blackstone’s parts and accessory availability at 28 inches is also the best in the category by some distance. Every cover, hood, spare top and burner assembly is easy to find, now and in several years.

Living with it

Bare carbon steel: season it before first use, scrape it hot after every cook, lay a thin oil film on while it is warm, and keep a vented cover on it. That is about a minute a cook and it is not optional on this surface.

Piezo ignition is the one component that commonly needs attention over time — it is a simpler, less durable system than the electronic ignition on the XL. Not a reason to avoid the griddle, just the thing most likely to annoy you first.

Who should buy it

Households of two to five who will do the maintenance and want the broadest accessory support available. If you want a third zone at the same footprint, the Weber Slate 30; if you want more heat in less space, the Traeger Flatrock 2-Zone; if you will skip the cover, the Weber.
