Quick Answer: Masterbuilt doesn’t make a dedicated pizza oven — the closest product is the Masterbuilt Pizza Oven (MB20181722), a $199.99 insert accessory (per Masterbuilt’s own site) that turns a compatible Gravity Series charcoal grill into a pizza setup, reaching roughly 700°F for a thin-crust pie. Buy it from Home Depot instead of Masterbuilt direct and it’s $169.99 — a real $30 gap on the identical SKU. If you searched “Masterbuilt pizza oven” expecting a standalone appliance like an Ooni or Gozney, this is the honest answer: it doesn’t exist, but this is the real product behind the search.
Why this search doesn’t have the answer people expect
Masterbuilt built its brand on smokers and the Gravity Series line of charcoal-fed grills, not purpose-built pizza appliances, and a check of its current catalog confirms there’s no Ooni-style gas-fired oven or Breville Pizzaiolo-style countertop unit anywhere in the lineup. What Masterbuilt does sell is the Masterbuilt Pizza Oven (model MB20181722) — a flat insert with a stainless-steel interior, porcelain-coated exterior, and an included pizza stone, designed to sit inside a Gravity Series grill’s cook chamber rather than function as its own appliance.
Masterbuilt pizza oven insert by the numbers
- $199.99 vs $169.99: Masterbuilt’s own direct price for the MB20181722 versus Home Depot’s listing for the same model — a genuine $30 gap that runs opposite to the usual pattern on this site, where buying direct from the brand is typically the floor, not a markup.
- 700°F in ~2.5 minutes: the insert’s rated performance for a thin-crust pizza per Masterbuilt’s own cooking guidance, or 600°F in about 5 minutes for a thick-crust pie — both figures depend on how hot the grill underneath actually runs, since the insert itself has no burner or heating element.
- 32.8” x 5.7” x 17.6”: the insert’s own listed dimensions, low-profile enough to sit inside a Gravity Series cook chamber in place of a cooking grate rather than bolt on as a separate unit.
- Grill-specific fit: built primarily for the Gravity Series 800 and 1050, and also compatible with the 600, 900, 1150, and XT models — but Masterbuilt explicitly lists the Gravity Series 560 as not compatible, so checking the exact model before buying matters.

What you actually get
Masterbuilt Pizza Oven (MB20181722)
- Stainless-steel interior insert with a porcelain-coated exterior and an included pizza stone, sized to sit inside a Gravity Series cook chamber.
- Reaches up to 700°F for a thin-crust pizza in roughly 2.5 minutes when paired with a Gravity Series 800 or 1050 running hot, per Masterbuilt's own cooking guidance.
- Check the exact model before buying — it fits the 600, 800, 900, 1050, 1150, and XT Gravity Series grills, but Masterbuilt lists the 560 as not compatible.
If you’d rather skip the grill-compatibility check entirely and just get a pizza night started, a dedicated oven ships as one complete kit — try Amazon Fresh for same-day dough, mozzarella, and San Marzano tomatoes so the first bake happens the day it arrives.
The Masterbuilt insert’s real strength is that it repurposes a Gravity Series grill you may already own, so there’s no second fuel source and no new appliance taking up patio space. What it can’t do is match a dedicated oven’s consistency — its actual ceiling depends entirely on how hot the grill underneath runs, where a purpose-built oven like the Ooni Koda 12 hits a known, fixed temperature every time.
Who should actually buy this
- Buy the Masterbuilt Pizza Oven insert if you already own a compatible Gravity Series grill and want an occasional pizza option without buying a second appliance — and buy it from Home Depot rather than Masterbuilt direct to save the $30.
- Own a different grill instead of a Gravity Series? The same “no standalone oven” story applies to several other grill brands — see our Weber and Traeger pizza oven guides for what those brands actually sell.
- Want a purpose-built pellet-grill insert instead? Green Mountain Grills makes a dedicated pizza attachment for its own pellet grills, covered in our separate GMG review. Our best pizza oven insert roundup compares this style across brands.
- Buy a dedicated gas oven like the Ooni Koda 12 instead if pizza is a regular habit — for close to the same all-in cost as the Masterbuilt insert, it reaches a higher, fixed peak temperature and doesn’t depend on owning a specific grill model first. See our best outdoor pizza oven roundup for the full field.
The bottom line
There’s no standalone “Masterbuilt pizza oven” — the honest answer to this search is the MB20181722 insert, a genuinely useful accessory for owners of compatible Gravity Series grills, but one whose real ceiling depends on the grill underneath it and whose direct price isn’t actually the cheapest place to buy it. It’s a reasonable pick if you already own a compatible Gravity Series grill and want pizza as an occasional bonus. If pizza is the actual priority, a dedicated oven from our best outdoor pizza oven guide will bake more consistently without any compatibility checks first.
