Best Gas Grill with Blackstone Griddle Combo 2026

Gas grill and Blackstone flat-top griddle combo unit cooking smash burgers on the griddle side and steaks on the grill grate side

The best gas grill with a Blackstone griddle combo is the Blackstone 36-inch 4-Burner with Grill Box — a single-unit setup that runs a full flat-top griddle alongside traditional grill grates simultaneously on one propane connection. The Blackstone Omnivore is the runner-up for cooks who want a single chassis that switches between griddle plates and grill grate inserts without adding a second unit.

Most backyards eventually end up with both a gas grill and a Blackstone griddle — one for grill-marked steaks and chicken, one for smash burgers, breakfast spreads, and hibachi-style cooking. Running both simultaneously means two large propane connections, two units fighting for patio space, and two surfaces to clean. Combination units solve this: Blackstone now builds several models that mount flat-top griddle surface and traditional grill grates on the same chassis, sharing one propane tank. Camp Chef offers a competing modular system. This guide covers which combination to buy at each size and budget level.

The picks

Best overall: Blackstone 36-inch 4-Burner with Grill Box

Best for households that want to cook smash burgers and grill steaks at the same time from one propane tank

Blackstone 36-inch 4-Burner Griddle with Grill Box Combo

The Blackstone 36-inch with Grill Box is the category-defining combo unit. The standard 36-inch Blackstone provides 756 square inches of rolled-steel flat-top cooking surface across four independently controlled burner zones. The grill box replaces one of those zones with a cast-iron grate section — the same type of grill grate you find on a standalone gas grill — connected to the same propane regulator. The result is a single unit where you can run smash burgers, eggs, or stir fry on the flat-top side while simultaneously cooking grill-marked chicken thighs or asparagus on the grate side. The four-zone burner system means you can set the griddle at medium-high for burger smashing while running the grill box at high for steakhouse-level surface searing, with two additional flat-top zones available for sides and warming. Total footprint is similar to a standalone 36-inch Blackstone — the grill box does not add significant width. A single 20-pound propane tank runs both surfaces, and the Blackstone accessory ecosystem (covers, lid, organizer, carry bag) is fully compatible with the combo configuration. At $500-650, this is the most straightforward answer to the 'gas grill with Blackstone' question.

Pros

Flat-top griddle and traditional grill grates operating simultaneously from one propane connection
Four independently controlled burner zones enable wide temperature range across both surfaces
Grill box accepts cast iron grates compatible with standard gas grill accessories
Full Blackstone accessory ecosystem works across the griddle side
Single footprint replaces what would otherwise be two separate propane units

Cons

Grill box zone reduces flat-top cooking area compared to the standalone 36-inch griddle
Cast iron grill grates in the box require separate seasoning and maintenance from the griddle surface
Simultaneous full-heat cooking on both sides can tax a standard 20-pound propane tank faster

Best modular pick: Blackstone Omnivore 36-inch

Best for cooks who want a single chassis that converts fully between flat-top griddle mode and traditional grill mode without a permanent grill box taking up griddle space

Blackstone Omnivore 36-inch 4-Burner Griddle and Grill

The Blackstone Omnivore takes a different approach from the grill box combo: instead of a permanent side-by-side configuration, it is a full 36-inch chassis that accepts interchangeable cooking surface inserts. Slide in the flat griddle plates for standard Blackstone flat-top cooking; swap to the grill grate inserts for traditional high-heat grill marks on steaks and chicken. The inserts cover the full cooking surface, meaning you get either 100 percent flat-top or 100 percent grill grate capacity — not a split. This matters for cooks whose sessions alternate between mode rather than needing both simultaneously. A full-surface flat-top breakfast on Saturday morning and a full-surface grill session for a Sunday cookout are both possible on the same unit. The Omnivore uses the same 4-burner layout as the standard 36-inch Blackstone, and the inserts swap without tools in a few minutes once the surface cools. The grill grate inserts give legitimate grill marks — the full-surface burner coverage means heat reaches the grates evenly across the width, a persistent weakness of small embedded grill boxes. At $600-750 including the insert kit, the Omnivore costs somewhat more than the grill box combo but provides full-surface capacity in each mode.

Pros

Full-surface griddle mode and full-surface grill mode — no capacity compromise from a permanent side-by-side split
Inserts swap without tools once the surface cools after a session
Even heat across the full width in grill mode — no cold spots from a small embedded box
Single chassis replaces both a standalone griddle and a gas grill
Compatible with standard Blackstone 36-inch accessories on the griddle side

Cons

Cannot run griddle and grill grates simultaneously — requires a full surface swap between modes
$600-750 is $100-150 more than the grill box combo for a fundamentally different use pattern
Insert storage requires dedicated space when not in use

Best mid-size combo: Blackstone 28-inch with Grill Box

Best for smaller patios and households of 2-4 who want the griddle-plus-grill combo without the 36-inch footprint

Blackstone 28-inch 2-Burner Griddle with Grill Box

The 28-inch version of the grill box combo scales down the Blackstone 36 concept for tighter outdoor spaces and smaller households. The standard 28-inch Blackstone delivers 470 square inches of flat-top cooking surface on two independently controlled burners; the grill box version replaces one of those burner zones with a cast-iron grill grate section connected to the same propane line. For a family of two to four, the resulting configuration is genuinely useful: run smash burgers or pancakes on the flat-top side while a few chicken breasts or salmon fillets take grill marks on the grate side. The 28-inch chassis fits in a smaller garage footprint, stores more easily for off-season, and uses less propane in a typical session. Where the 36-inch combo handles a party-size cook without constraint, the 28-inch is a weeknight dinner unit — sized right for everyday use. Two-burner control provides a meaningful hot and warm zone on the flat-top side despite the smaller size. At $380-480, it is the most accessible entry point into the combo category and a practical choice for renters or homeowners with limited patio space.

Pros

Smaller footprint than the 36-inch combo — fits tighter patios and stores in less garage space
Right-sized for 2-4 people on weeknight dinners without wasted surface area
Lower propane consumption than a full 36-inch unit in day-to-day use
Lower price of entry ($380-480) versus the 36-inch combo at $500-650
Two-burner control still provides hot and warm zones on the griddle side

Cons

Grill box takes one of two burner zones, reducing flat-top area significantly versus the standalone 28-inch griddle
Party-size cooking (6+ people simultaneously) is constrained on the 28-inch combo
Two total burners means less temperature range versatility than the 36-inch four-burner layout

Best non-Blackstone combo: Camp Chef Flat Top 600 with Grill Box

Best for cooks who want a premium-build modular flat-top with grill capability and are not committed to the Blackstone ecosystem

Camp Chef Flat Top 600 with Grill Box Accessory

Camp Chef's Flat Top 600 is the serious alternative to Blackstone for outdoor flat-top cooking, and it extends into combo territory through a modular grill box accessory that attaches to the right side of the unit. The FT600 runs four burners at a total output that rivals the 36-inch Blackstone, but on a cold-rolled steel surface that Camp Chef considers higher grade than Blackstone's rolled steel — it seasons and maintains a nonstick patina comparably, and early-generation Camp Chef griddles show less warping at high heat over multi-year use. The grill box accessory slides into the side accessory mount, sharing the same propane regulator, and provides a cast-iron grate cooking zone equivalent to a small gas grill burner section. Camp Chef's accessory ecosystem is extensive: the same side mount accepts a wok ring, a griddle insert, a pizza oven attachment, and other accessories interchangeably. For cooks who want a premium flat-top that expands with accessories over time, the FT600 plus grill box provides a cleaner, more modular system than the fixed grill box on a Blackstone combo. At $550-700 combined (unit plus grill box accessory), it is competitively priced against the Blackstone 36-inch grill box combo.

Pros

Premium cold-rolled steel surface with consistent seasoning performance and less warping over time
Modular accessory system — grill box, wok ring, pizza oven, and more all use the same side mount
Four burners with high total BTU output comparable to the Blackstone 36-inch
Camp Chef accessory ecosystem allows the unit to expand well beyond griddle-plus-grill over time
Cleaner modular design than a fixed grill box — remove the grill box for full griddle capacity when needed

Cons

Camp Chef accessory ecosystem is smaller than Blackstone's in total accessory variety
$550-700 combined (unit plus grill box) is at the high end of the combo price range
Less common in retail stores — Blackstone is easier to find locally for in-person inspection

Best two-unit setup: Weber Spirit II E-310 + Blackstone 28-inch

Best for cooks who prioritize best-in-class output at both categories and have patio space for two dedicated units

Weber Spirit II E-310 Gas Grill (to pair with Blackstone 28)

The two-unit setup — a Weber Spirit II E-310 gas grill alongside a standalone Blackstone 28-inch griddle — outperforms every combo unit in outright cooking quality at each category. The Weber Spirit II is the most-recommended entry gas grill in the market: three burners, 30,000 BTU, porcelain-enameled cast iron grates, Flavorizer bars, and a 10-year warranty on the firebox. It produces proper grill-marked steaks, chicken thighs with crispy skin, and hot dogs in a way that a grill box embedded in a Blackstone chassis cannot quite replicate at full capacity. Paired with a standalone Blackstone 28-inch — 470 square inches, two independent zones, the full-surface flat-top experience — the combination gives you a professional-grade tool at each category. The tradeoff is two propane connections, two units to maintain, and two footprints on your patio. At $280-360 for the Blackstone 28 and $550-650 for the Weber Spirit II, total cost is $830-1,000 combined — meaningfully more than a single combo unit but with substantially better output at both cooking modes. This setup makes sense when patio space is not the constraint and cooking quality is the priority.

★★★★★ 4.8 · 6,400 reviews

Check current price on Amazon→

Pros

Best-in-class cooking quality at each category — dedicated full-size gas grill and dedicated full-size griddle
Weber Spirit II delivers 10-year warranty coverage; standalone Blackstone 28 has full accessory compatibility
Both units benefit from their own full accessory ecosystems without compromise
Full cooking surface area at each unit — no capacity reduction from sharing space with the other mode
Either unit can be upgraded or replaced independently without affecting the other

Cons

$830-1,000 combined versus $380-650 for a single combo unit
Two propane connections and two units to maintain, season, and store
Requires more patio space — two large units side-by-side versus one combo footprint

What to skip

Generic grill and griddle “combo” units under $300. Several brands sell gas grills with a small griddle insert (a flat plate that replaces one burner zone of grates) at $200-280. The griddle insert is typically six to eight inches wide — large enough to cook two eggs, not large enough for smash burgers or a real breakfast spread. These units deliver neither a genuine griddle nor a genuine grill at any usable capacity. Avoid them.

Standard gas grills with a reversible grill/griddle grate. Some grills (and most camp stoves) sell a reversible grate that is standard grill bars on one side and a flat plate on the other. The flat side heats unevenly, has inadequate surface mass for proper flat-top cooking, and cannot be seasoned the way a proper rolled-steel or cast-iron griddle surface can. This is not a substitute for a Blackstone griddle surface — it is a griddle-flavored accessory on a grill.

No-name flat-top grill combos on marketplace sites. Blackstone and Camp Chef have invested in surface material, ignition, and burner tube engineering that produces consistent, long-term performance. Generic griddle-grill combos from no-name brands cut corners on burner tube quality (aluminum tubes corrode faster than stainless), surface steel thickness (thin steel warps at high heat), and ignition reliability. At $200-350 for a combo from an unfamiliar brand, the failure risk is high enough to make the Blackstone 28 combo at $380-480 the correct starting point.

FAQ

Frequently asked questions

What is the best gas grill with Blackstone griddle combo?

The Blackstone 36-inch 4-Burner with Grill Box is the best overall combo — it runs a full flat-top griddle and traditional grill grates simultaneously on one propane connection. For smaller patios, the Blackstone 28-inch with Grill Box is the right-sized version of the same concept. If you want a single surface that converts fully between modes rather than a side-by-side split, the Blackstone Omnivore 36 is the best choice.

Blackstone Omnivore vs Blackstone Grill Box Combo — which is better?

The grill box combo is better if you need to cook on both surfaces at the same time — smash burgers on the griddle while steaks take grill marks simultaneously. The Omnivore is better if you prefer full-surface cooking in each mode separately and dislike the capacity compromise of a permanent grill box taking up griddle space. Most households end up preferring the grill box combo because simultaneous dual-surface cooking is the primary reason to buy a combo unit.

Can I attach a Blackstone griddle to my existing gas grill?

Not directly. Blackstone griddles use their own propane regulator and chassis; they do not attach to or share propane with a standalone gas grill. The combo units are built at the factory to share a propane source across both surfaces. If you already own a Weber or other gas grill, adding a standalone Blackstone 28 beside it as a second unit is the practical approach — two units sharing patio space rather than one integrated chassis.

What size Blackstone combo should I get?

The 36-inch combo is right for households of 4 or more and anyone who hosts regularly. It handles simultaneous family-size cooking on both the griddle and grill sides without constraint. The 28-inch combo is right for 2-4 people and tighter patios — it reduces flat-top capacity compared to a standalone 28-inch Blackstone, but the dual-surface convenience compensates for most households at that scale.

Is a combo unit as good as buying a dedicated gas grill and dedicated Blackstone separately?

No — two dedicated units outperform a combo at both cooking categories. A Weber Spirit II delivers better gas grill performance than a grill box embedded in a Blackstone chassis, and a standalone Blackstone 36 delivers better griddle performance than the griddle side of a combo with a grill box cutting into total surface area. The combo wins on footprint, price, and convenience; two dedicated units win on output quality. Choose based on whether space or cooking performance is your primary constraint.

Does the grill box use the same propane tank as the Blackstone griddle?

Yes — the grill box on a Blackstone combo connects to the same propane regulator that feeds the griddle burners. A standard 20-pound propane tank runs both surfaces. Running both the griddle and grill box at high heat simultaneously will deplete a propane tank faster than running the griddle alone, but a single full tank is adequate for a typical backyard session on both surfaces.

Bottom line

Best overall combo: Blackstone 36-inch 4-Burner with Grill Box ($500-650) — full flat-top griddle and grill grates running simultaneously on one propane tank. Best modular pick: Blackstone Omnivore 36 ($600-750) for full-surface griddle or full-surface grill mode on a single chassis. Best for smaller patios: Blackstone 28-inch with Grill Box ($380-480) — same concept at a footprint that works for most residential outdoor spaces. Best non-Blackstone option: Camp Chef Flat Top 600 with Grill Box ($550-700) for premium steel construction and a fully modular accessory system. Best two-unit setup: Weber Spirit II E-310 plus Blackstone 28 ($830-1,000 combined) when patio space is available and cooking quality at both modes is the priority.

If patio space is the main constraint and you want both cooking surfaces on one unit, the Blackstone 36-inch grill box combo is the most practical answer. If cooking quality at each mode matters more than footprint, buy the best dedicated unit at each category and run them side by side.
