Blackstone 28" XL Omnivore Griddle: 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 actually differs

Blackstone’s Original line uses bare rolled carbon steel — on the 28 that is a 10-gauge plate. This is the classic flat-top surface: season it, it becomes genuinely non-stick, and it can be restored indefinitely.

The Omnivore plate is a different cooking surface. It is not a non-stick coating in the Pit Boss sense, and it is not the bare rolled steel of the Original either. Practically, it takes seasoning differently.

This matters mainly because most seasoning advice online is written for bare carbon steel, and people applying it to an Omnivore plate conclude their griddle is defective when the first few rounds look different from the photographs.

Season it per the plate, not per the internet

The universal principles still hold: very thin coats, heat until the smoking stops, repeat. What changes is appearance and how quickly the surface darkens.

Follow Blackstone’s guidance for the Omnivore plate specifically. A patchy, bronze surface after the first round is not a failure — it is a new griddle, and this is where people make the classic mistake of compensating with a thicker coat, which produces the sticky finish that eventually flakes off.

Our Blackstone seasoning guide covers both surfaces.

The configurations differ too

The lines are not just two surfaces on identical bodies. Omnivore configurations tend to carry other differences — the 28″ XL Omnivore has three burners and electronic ignition against the standard 28’s two burners and piezo, plus 88 more square inches.

So in practice you are rarely choosing a plate in isolation. You are choosing a configuration that happens to come with a plate, which is why the 28 versus 28 XL comparison is the more directly useful page for most buyers.

Check the BTU rating on Omnivore models

The 28″ XL Omnivore body is listed at 28,500, 45,000 and 48,000 BTU across different retailers, all at 613 square inches. That is a 46.5 to 78.3 BTU-per-square-inch range — the difference between the weakest cart griddle in our guide and one of the strongest.

Read the spec panel on the exact listing. This is the single most important thing to do when buying an Omnivore model.

Which to choose

Original if you want the classic, well-documented carbon-steel experience with a thick plate, abundant community knowledge and a predictable BTU figure.

Omnivore if the configuration you want — usually more zones for the footprint — comes on that plate, and you are comfortable following plate-specific seasoning guidance and checking the spec panel.

#1 · Most households

Blackstone 28" Original Griddle

8.4/ 1064.8 BTU per sq in

The size most people should actually buy: 525 square inches and two zones covers a family of four with headroom, on a footprint that fits a normal patio.

Scores

  • Cooking area7.5
  • Heat output7.0
  • Zone control7.0
  • Surface care6.5
  • Portability5.0

What works

  • The 10-gauge plate is thicker than most griddles at this size, which is what keeps temperature steady when cold food hits it
  • Two zones is genuinely enough: one hot side for searing, one moderate side for holding
  • Fits a standard patio and a standard cover, which the 36 often does not

What to know

  • Only two zones — you cannot run a dedicated warming zone and two cooking temperatures at once
  • 34,000 BTU over 525 sq in is modest heat density; recovery after a big load is slower than the 36
  • Bare carbon steel needs seasoning and a cover, same as every Blackstone

#2 · Three zones without the 36's footprint

Blackstone 28" XL Omnivore Griddle

7.9/ 1073.4 BTU per sq in

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.

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.

Scores

  • Cooking area8.0
  • Heat output7.5
  • Zone control8.5
  • Surface care6.5
  • Portability4.0

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

Common questions

What is the difference between Blackstone Original and Omnivore?
The cooking surface. Original uses bare rolled carbon steel — the classic flat-top surface that seasons to a non-stick finish and can be restored indefinitely. The Omnivore plate is a different surface that takes seasoning differently, so the early rounds look different from standard carbon-steel photographs.
Does the Omnivore plate need seasoning?
Yes, and the universal principles apply — very thin coats, heat until the smoking stops, repeat. What differs is appearance and how quickly it darkens. Follow Blackstone's plate-specific guidance rather than generic carbon-steel advice.
Is Original or Omnivore better?
You are rarely choosing a plate in isolation — Omnivore configurations usually carry other differences, like the 28-inch XL's third burner and electronic ignition. Choose the configuration you want, then follow the right seasoning guidance for whichever plate it comes with.
