Three zones without the 36’s footprint
This is the model’s reason to exist. 613 square inches with three independently controlled burners gives you a genuine holding zone on top of two cooking temperatures, in a body that is still meaningfully smaller than a 36.
Against the standard 28 (525 sq in, two zones), you gain 88 square inches and — more importantly — the third zone. Against the 36 (769 sq in, four zones), you give up 156 square inches and one zone but get a griddle that fits where the 36 does not.
Electronic ignition is also a quiet upgrade over the standard 28’s piezo button: it is the more durable system, and ignition is the component most likely to irritate you over time.
The BTU problem, stated plainly
This body is sold at three different BTU ratings. Academy lists it at 28,500 BTU. Other retailers list the same 613 square inches at 45,000 and at 48,000.
That is not a rounding difference. At 613 square inches those work out at 46.5, 73.4 and 78.3 BTU per square inch respectively — the bottom figure is the lowest heat density of any cart griddle in our guide, and the top figure is among the highest. They are, functionally, different griddles sharing a body.
We are not going to resolve this for you by picking a number, because the number genuinely varies by variant and model year. Read the BTU figure off the exact listing you are buying. If it says 28,500, understand that you are buying a large plate with modest heat behind it.
The Omnivore plate
The Omnivore cooktop is a different surface from the classic Blackstone carbon steel plate, and it takes seasoning differently. It is not a coated non-stick surface in the Pit Boss sense, but it is also not the bare rolled steel that the 28 Original uses.
Practically, follow Blackstone’s own guidance for this plate rather than generic carbon-steel advice, and expect the first few seasoning rounds to look different from what you would see on a classic top. Our Blackstone seasoning guide covers both surfaces.
Who should buy it
Someone who wants three zones, has room for a cart but not a 36, and is willing to check the spec label before buying. That last condition is doing real work — this is the one griddle in our guide where buying carelessly can land you with meaningfully less griddle than you thought.
If you want three zones with no ambiguity at all, the Weber Slate 30 is a straightforward 36,000 BTU across 540 square inches with a rust-resistant top.

Blackstone 28" XL Omnivore Griddle
Three zones in a 613-square-inch body — the useful middle ground — but the BTU rating genuinely varies between variants, so read it off the listing in front of you.

Specifications from Academy Sports listing.
Listings disagree: Retailers list this body at 28,500 BTU (Academy), 45,000 BTU and 48,000 BTU — all at 613 sq in. The surface area is settled; the heat output is not. Check the BTU figure on the exact listing you are buying.

What works
- Three zones at 613 sq in is the best zone-to-footprint ratio Blackstone sells
- Electronic ignition is more reliable over time than a piezo button
- Meaningfully more surface than the 28 without the 36's storage problem
What to know
- The BTU rating is not consistent across listings — the same 613 sq in body appears at 28,500, 45,000 and 48,000 BTU
- A 28,500 BTU example over 613 sq in is thin heat; that variant recovers slowly
- The Omnivore plate is a different surface from the classic carbon steel and takes seasoning differently
