Best Kamado Grill: Ceramic vs Steel vs Cast Aluminum

Kamado grills — thick-walled ceramic cookers shaped like an egg — hold heat with remarkable efficiency, letting the same unit handle a 225°F overnight smoke and a 750°F pizza night. Here’s how four of the most established kamado options compare.

1. Kamado Joe Classic III

The Classic III is Kamado Joe’s flagship 18-inch model, featuring the “Divide & Conquer” rack system (two half-moon racks that can be stacked at different heights for multi-zone cooking) and a “SloRoller” insert for low-and-slow smoking without flare-ups.

• Pros: Excellent heat retention, flexible multi-level cooking racks, thick ceramic shell holds temperature in cold weather.
• Cons: Heavy and not easily portable; premium price reflects the build quality.

2. Weber Summit Kamado S6

Weber’s entry into the kamado category pairs a cast-aluminum body (lighter and more crack-resistant than ceramic) with a stainless steel cart and the same Gourmet BBQ System grate used on Weber’s kettle grills, so accessories cross over between product lines.

• Pros: Cast-aluminum shell resists cracking better than ceramic, interchangeable grate accessories, sturdy cart.
• Cons: One of the pricier options in the category; large footprint.

3. Char-Griller E16620 Akorn Kamado Kooker

The Akorn delivers the kamado cooking format in a double-walled steel body instead of ceramic, which cuts both weight and price dramatically while still holding heat reasonably well for shorter cooks.

• Pros: Far more affordable than ceramic kamados, decent heat retention, easier to move.
• Cons: Steel body doesn’t insulate quite as well as ceramic over very long smokes; gaskets may need replacing after heavy use.

4. Vision Grills Classic B Series Kamado

Vision Grills offers a traditional ceramic kamado at a lower price point than Kamado Joe or Big Green Egg, including features like a built-in thermometer and a locking hinge system, aimed at buyers who want ceramic performance without the flagship price tag.

• Pros: Ceramic heat retention at a mid-range price, built-in thermometer, locking lid hinge.
• Cons: Smaller accessory ecosystem than the market-leading brands.

5. Big Green Egg (Medium)

Big Green Egg is the brand that popularized the kamado format in the US, and the Medium size — 15-inch cooking grate, roughly 177 square inches — remains one of the most recognized ceramic kamados on the market. It uses the same patented airflow system and calibrated temperature gauge found across the Big Green Egg lineup, backed by a limited lifetime warranty on the ceramic components.

• Pros: Market-leading brand recognition and resale value, lifetime warranty on ceramic parts, huge third-party accessory ecosystem (nests, tables, EGGcessories).
• Cons: Smaller cooking area than Kamado Joe Classic III or Weber Summit S6 at a similar price point; accessories are sold separately and add up quickly.

How to Choose a Kamado Grill

• Body material: Ceramic holds heat longest and insulates best but is heavy and can crack if dropped; cast aluminum and double-wall steel are lighter and more impact-resistant.
• Size: Most kamados are sized by grate diameter (15–24 inches); an 18-inch grate suits most families, larger sizes suit entertaining.
• Airflow control: Look for a top damper and bottom vent that let you dial in temperature precisely — this is the core of what makes kamado cooking work.
• Accessories: Pizza stones, half-moon racks, and ash tools vary by brand; check what’s included versus sold separately.

Sizing a Kamado to How You Actually Cook

Kamado sizing is one of the most commonly second-guessed decisions in this category, because a bigger grate seems like an obvious upgrade until you’re trying to light and heat-soak a large ceramic shell just to cook two steaks. A 13-15 inch grate comfortably handles 2-4 people and heats up faster with less charcoal; an 18-inch grate suits families who regularly cook for 4-6; anything above 20 inches is really built around entertaining groups or cooking multiple proteins at once, and takes noticeably longer to reach a stable temperature. If most of your cooking is weeknight dinners for a small household, sizing down saves both charcoal and your time waiting for the grill to heat-soak.

Frequently Asked Questions

Can a kamado grill really make pizza?

Yes — kamados can reach 600–750°F with the damper wide open, which is hot enough for a legitimate Neapolitan-style pizza crust using a pizza stone insert.

Is ceramic or steel better for a kamado?

Ceramic generally insulates better for very long, low-temperature smokes, while steel/aluminum bodies are lighter, less fragile, and typically cheaper — a reasonable tradeoff for buyers who don’t do 12+ hour cooks often.

Do kamado grills need special charcoal?

Lump charcoal is strongly recommended over briquettes for kamados — briquette binders and fillers create more ash, which can clog the airflow holes in the firebox.

How much does a ceramic kamado weigh, and does that matter?

Most full-size ceramic kamados weigh 150-250 pounds once mounted in their cart or nest, which is part of why they’re treated as semi-permanent patio fixtures rather than something you move around. It’s worth confirming your deck or patio surface can handle that weight concentrated in one spot, and that you have a flat, stable base before it’s assembled rather than after.

Can a kamado grill be used in the rain?

Yes, ceramic kamados handle rain fine during use since the dome sheds water and the firebox stays dry, but a grill cover between uses is still recommended — repeated soaking of the felt gasket (the seal between the lid and base) can shorten its lifespan and eventually require a gasket replacement.
