Masterbuilt Pizza Oven Review (2026): Is It Worth It? + Better Alternatives

Read this before anything else: the Masterbuilt pizza oven is an insert, not a standalone oven. The Masterbuilt Gravity Series Pizza Oven is an accessory designed to drop into a Masterbuilt Gravity Series charcoal grill, converting that grill into a high-heat pizza oven. It has no fire, fuel, or function of its own, it relies entirely on the grill's gravity-fed charcoal fire for heat. The product name says "pizza oven," but what you're buying is a conversion kit for a specific grill.

For the existing Gravity Series owner, the insert's case is genuinely good: it leverages a grill you already love, adds high-heat pizza to its repertoire, and costs far less than a separate oven. That's the buyer this product is built for, and for them it's a clever upgrade. But for a shopper who arrived searching "Masterbuilt pizza oven" expecting a buy-it-and-use-it oven, the honest answer is that this isn't one, and the standalone ovens below are what you should actually compare. The kindest thing a review can do is make sure you know what's in the box before you order it.

The standalone answer for anyone without the grill. The Ooni Karu 12 gives you the charcoal-and-wood live-fire flavor that the Masterbuilt-plus-grill setup produces, but as a complete, standalone oven that needs nothing else. It verifiably reaches a true ~950°F, it accepts an optional gas burner for easy heat, and it works straight out of the box without owning a separate grill. For the very common buyer who searched "Masterbuilt pizza oven" and discovered it's an insert, this is the real oven that does the job.

It's a personal-to-medium 12-inch oven and wood mode asks for fire management, like any live-fire oven. But as a complete standalone oven with the same charcoal-fired character, it's the first alternative a non-grill-owner should price against the Masterbuilt insert, a real oven, no grill required.

The complete oven that needs nothing else. The Ooni Koda 16 is our default great gas recommendation: it verifiably hits a true ~950°F floor, and its L-shaped burner bakes evenly across a full 16-inch surface with no grill, no charcoal, and no fire to manage. Where the Masterbuilt insert is one part of a two-part setup, the Koda 16 is the whole thing, turn it on, wait for the stone, make pizza.

It's gas-only with no charcoal flavor and more than the insert's sticker price, so it's not the pick if you already own the grill or want live-fire flavor. But for a buyer without the Gravity Series who wants a complete, high-performance oven, the Koda 16 is the clear standalone destination, no grill, no compromise.

A complete budget oven, no grill needed. The Pizzello 16 is a standalone multi-fuel oven, propane and wood, with a full 16-inch surface and a stated ~930°F, all for $329. Unlike the Masterbuilt insert, it's a usable oven on its own: nothing else to own, nothing else to buy. For a budget buyer who discovered the Masterbuilt requires a grill, the Pizzello is the affordable standalone way to get full-size, Neapolitan-range pizza.

It's a budget brand, so build varies and the temp is stated, not clocked, and at 16 inches and 50 lb it's larger to store. But as the complete, affordable standalone multi-fuel oven, it's the budget alternative a non-grill-owner should price against the Masterbuilt insert.
