Best Pizza Stones and Ovens for Grills

A grill can bake good pizza if something holds heat under the crust and above the toppings. A stone on the grates is the cheapest way; a kettle insert traps heat under a raised lid; a standalone pizza oven gets far hotter than either. This guide compares five options, using manufacturer specs, Keepa price history and the ratings on each listing. Prices were checked when the page was last updated; Amazon's checkout price is the one that counts.

The Picks

1. BIG HORN 12" Pellet Pizza Oven

$149.99 on Amazon →

The BIG HORN 12" Pellet Pizza Oven (SRPG18003) is a stainless steel oven that burns hardwood pellets. BIG HORN says it is ready in 18 to 20 minutes, reaches 1,110°F at maximum and bakes a pizza in 60 to 90 seconds on its 12 by 12 inch stone. It weighs about 25 lb, has folding legs and comes apart without tools for cleaning.

It is not a grill accessory: it sits on a table beside the grill. Gas and electric burners are sold separately, pellets need topping up during a session, and BIG HORN's own instructions say to turn the pizza often for an even bake.

• Best for: Neapolitan-style pizza with a charred, puffy crust.
• Who should skip it: anyone who wants to use the grill they already own.

2. onlyfire Kettle Pizza and Rotisserie Kit

$152.99 on Amazon →

The onlyfire Kettle Pizza and Rotisserie Kit (F-BRK6055-SS1) is a stainless ring that sits between the bowl and lid of a 22" kettle. A door in the ring lets you slide pizzas in without lifting the lid, swiveling dampers hold the heat in, and the kit includes a 15" round pizza stone, a peel, a thermometer and a rotisserie with a 110V motor. About 2,000 ratings average 4.6.

onlyfire says it does not fit the Weber Smokey Mountain or the 22" Slow 'N Sear kettle. At the last check it was sold by third-party sellers.

• Best for: Weber 22" kettle owners who want pizza and rotisserie from one kit.
• Who should skip it: gas grill owners, and anyone who only wants a stone.

3. LS'BABQ Glazed Stone for Weber Crafted

$54.99 on Amazon →

The LS'BABQ Glazed Stone for Weber Crafted is a third-party replacement for Weber's 7671 Crafted baking stone, made of glazed cordierite and sized for the Weber Crafted frame used on recent Genesis grills. The listing names the compatible models in detail, so check yours against it. About 60 ratings average 4.3.

It only makes sense if your grill already has, or you will buy, the Crafted frame. On any other grill a plain stone does the same job for less.

• Best for: Weber Genesis owners using the Crafted system.
• Who should skip it: everyone without the Crafted frame.

4. ROCKSHEAT 15x12 Rectangular Stone

$25.99 on Amazon →

The ROCKSHEAT 15x12 Rectangular Stone (RS30038016H) is a cordierite stone 15 by 12 inches and 0.63 inches thick, weighing 7.4 lb, with handles cut into the edges. ROCKSHEAT rates it to 1,400°F. With about 4,200 ratings at 4.5, it is the most widely bought option here.

A stone on grill grates heats from below only, so the top of the pizza cooks more slowly than the crust. Close the lid, preheat the stone fully, and expect a crisp base rather than a pizzeria char.

• Best for: most gas and charcoal grills, and the kitchen oven.
• Who should skip it: small portable grills where 15 inches will not fit.

5. ROCKSHEAT 12.6 Round Stone

$21.99 on Amazon →

The ROCKSHEAT 12.6 Round Stone (RS32015H) is the round version: 12.6 inches across, 0.63 inches thick, with built-in handles, also rated to 1,400°F. About 2,300 ratings average 4.4.

Its size limits pizzas to about 12 inches, and the handles take up some of the baking surface.

• Best for: small and portable grills, and kettle owners who want a stone without a ring kit.
• Who should skip it: anyone baking large pizzas or bread loaves.

How to Choose

• How hot you need. A stone on a grill bakes a crisp New York-style crust; a pizza oven at 900°F and above makes Neapolitan pizza.
• What you own. Kettle kits fit kettles, Crafted stones fit Crafted frames, plain stones fit almost anything.
• Size. Measure the grate: leave room around the stone so heat can rise and the lid can close.
• Cordierite. Cordierite tolerates sudden temperature changes better than ordinary ceramic, which is why it is common in grill stones.

Frequently Asked Questions

Do I need a pizza oven, or will my grill do?

A grill with a stone and a closed lid makes good pizza. A dedicated oven is worth it only if you want very high heat and fast, charred Neapolitan-style pies.

How do I stop pizza sticking to the stone?

Dust the peel with semolina or cornmeal, preheat the stone fully, and slide the pizza on with a quick jerk. Do not oil a stone.

Can I use a pizza stone on a charcoal grill?

Yes. Bank the coals to the sides or use a ring kit so the stone does not sit over the hottest spot, which can burn the base before the top is done.

How do I clean a pizza stone?

Let it cool fully, scrape off stuck food, and wipe with water only. Soap soaks into the stone. Dark stains are normal and do not affect baking.

Why did my pizza stone crack?

Usually thermal shock: putting a cold or wet stone into a hot grill, or cold water onto a hot stone. Heat the stone up with the grill and let it cool down in it.
