Blackstone Pizza Oven Add-On Review (2026): 750°F Pizza in 2–4 Minutes

The Blackstone Pizza Oven Add-On turns your 22-inch Blackstone griddle into a high-temperature pizza oven capable of 750°F — hot enough to cook a Neapolitan-style pizza in 2–4 minutes. Two cordierite baking stones (15” diameter each), a built-in temperature gauge, and a domed lid that concentrates heat above the stone. This is Blackstone’s answer to the discontinued original pizza oven, and it’s specifically designed for the 22-inch Blackstone models only.

Pros

• 750°F max temperature rivals dedicated outdoor pizza ovens
• 2–4 minute pizza cook time — genuinely fast, Neapolitan-style results
• Two cordierite baking stones provide even heat from below
• Built-in temperature gauge means no separate thermometer needed
• Uses your existing 22-inch Blackstone and propane setup — no extra fuel source
• Cordierite stones absorb moisture for a crispy crust

Cons

• Only compatible with 22-inch Blackstone models — won’t work with 17-inch, 28-inch, or 36-inch
• 50 lbs — adds significant weight to your 22-inch griddle setup
• Takes 15–20 minutes to fully preheat to pizza temperature
• High heat requires careful management to avoid burning the crust before the top cooks through
• Stones require careful handling — cordierite can crack if thermally shocked (cold water on hot stone)

Who Should Buy This

Buy it if: You already own a 22-inch Blackstone griddle and want to add outdoor pizza-making capability without buying a dedicated pizza oven. The conversion kit turns an existing asset into a dual-function outdoor cooking station.

Skip it if: You own a 17-inch, 28-inch, or 36-inch Blackstone — the add-on only fits 22-inch models. Also skip if you cook pizza infrequently; dedicated outdoor pizza ovens (like the Ooni Koda) are purpose-built for that task and may deliver better results for single-use pizza cooking.

What Is Cordierite and Why Does It Matter for Pizza?

Cordierite is a mineral used in baking stones because of two properties: it tolerates extreme temperature changes without cracking (important in a 750°F oven), and it pulls moisture from pizza dough during baking. The moisture-wicking property is what creates a crispy bottom crust — the stone draws humidity out of the raw dough as it cooks. Two stones in the Blackstone add-on means the bottom heat source (lower stone) and the upper radiant heat source combine for even top-and-bottom cooking.

Critical care note: Never put a hot cordierite stone in water or pour cold water on it while hot — thermal shock can crack it. Let it cool completely at room temperature after use.

How Long Does It Take to Preheat?

Budget 15–20 minutes from cold start to pizza-ready temperature. The dome has to saturate the cordierite stones with heat before the stone can deliver the consistent bottom crust needed for quality pizza. The built-in gauge tells you when you’ve hit pizza temperature — don’t rush it.

How It Compares

• vs. Dedicated outdoor pizza ovens (Ooni Koda, etc.) — Dedicated pizza ovens are purpose-built, reach temperature faster, and often reach higher peaks (950°F+). The Blackstone add-on is a better choice if you already own a 22-inch Blackstone and want a dual-purpose setup rather than a dedicated unit.
• vs. Blackstone original pizza oven (discontinued) — This add-on replaces the discontinued standalone model. If you’re looking for the original, this is the current Blackstone pizza option.

Our Verdict

The Blackstone Pizza Oven Add-On is an excellent expansion for 22-inch Blackstone owners who want to cook quality pizza outdoors. 750°F, 2–4 minute cook times, and two cordierite stones deliver genuine results. The compatibility limit (22-inch only) and 50-lb weight are the main constraints to check before buying. If you own a compatible griddle and want to add outdoor pizza capability without buying a separate appliance, this is the right add-on.

Frequently Asked Questions

What Blackstone models is the pizza oven add-on compatible with?

The pizza oven add-on is only compatible with 22-inch Blackstone griddle models. It does not fit the 17-inch, 28-inch, or 36-inch models.

How hot does the Blackstone Pizza Oven Add-On get?

Up to 750°F, which is sufficient for Neapolitan-style pizza in 2–4 minutes. Most home ovens reach 450–500°F, so 750°F delivers a significantly different crust and char.

Can you cook things other than pizza in the add-on?

Yes — the 750°F temperature and dome setup work for flatbreads, calzones, and any other high-heat oven cooking. The cordierite stones are versatile for baking bread as well.

How do you care for cordierite baking stones?

Let them cool completely before cleaning — never use cold water on a hot stone. Scrape off food debris with a brush or scraper when cool. Do not use soap; it absorbs into the stone. Store dry to prevent cracking.
