Quick Answer: The best pizza oven insert of 2026 is the Solo Stove Pi Fire ($260-300) —
a stainless dome that drops onto a Solo Stove Bonfire, Ranger, or Yukon fire pit and turns it into a
wood-fired pizza oven in under a minute. Already run a pellet grill instead? The Stanbroil Pellet
Grill Pizza Oven Attachment fits 60+ Traeger, Pit Boss, and Camp Chef models for well under $200.
Premium fire-pit owners should look at the Breeo Live-Fire Pizza Oven ($850), and budget shoppers
who don’t yet own a fire pit or grill can skip the insert route entirely with the standalone
Pizzello Gusto 4-in-1 (~$90-150). Confirm your exact fire pit or grill model fits before buying —
these are not universal.
If you already own a fire pit or a pellet grill, a full standalone pizza oven can feel redundant — you’ve already got the fuel source and the outdoor real estate. A pizza oven insert (sometimes sold as an “attachment”) solves that: it’s a dome, hood, or firebox topper that converts equipment you already own into something that bakes a real pizza. We dug through the current lineup from Solo Stove, Breeo, and the third-party pellet-grill accessory makers to find the ones that actually fit and actually get hot. Here are the five worth buying, ranked by use case.
Pizza oven inserts by the numbers
- ~650°F: the maximum stone temperature Solo Stove lists for the Pi Fire insert, well above a home oven’s roughly 550°F ceiling but below the 900°F+ a standalone gas oven like the Ooni Koda reaches.
- $850: the price of Breeo’s Live-Fire Pizza Oven insert on its own — more than most standalone gas ovens — plus a separate $179 adapter required for X30-series fire pit owners.
- 60+ models: the number of pellet grills (Traeger, Pit Boss, Camp Chef, Green Mountain, Z Grills, Rec-Tec, Smokin Brothers) Stanbroil’s attachment lists as compatible, per its Amazon listing.
- Model-specific fit: every insert on this page is sized to a specific fire pit or grill family — none are truly universal, so checking exact dimensions before buying matters more than with a standalone oven.

1. Solo Stove Pi Fire — the best overall pizza oven insert
Solo Stove Pi Fire
- Stainless dome sized to fit directly onto a Solo Stove Bonfire, Ranger, or Yukon fire pit — no separate adapter needed.
- Includes a cordierite pizza stone (Amazon lists it rated to roughly 650°F) plus a carry case and wood-burning assembly.
- Built-in handles make it genuinely portable between the fire pit and storage — not a permanent fixture.
If you already own a Solo Stove fire pit, this is the least friction way to bake pizza on it. The dome drops on in place of the standard lid, the included stone gets hot enough for a real crust in a few minutes, and because it’s sized per fire pit (Bonfire vs. the smaller Ranger vs. the larger Yukon) you get an actual fit rather than a generic “one-size-fits-most” claim. It’s also the cheapest way into Solo Stove’s pizza lineup — Solo Stove’s own standalone Pi oven runs $400+ on top of whatever fire pit you’d still need to buy separately.

2. Breeo Live-Fire Pizza Oven — best premium fire-pit insert
Breeo Live-Fire Pizza Oven
- Converts a Breeo X24, X30, or Luxeve fire pit into a pizza oven, per Breeo's product page.
- Extra-thick pizza stones and an adjustable chimney vent for finer temperature control than most fire-pit inserts offer.
- X30 owners need the separate Pizza Oven X30 Adapter (~$179) — factor that into the total before buying.

Breeo’s insert costs more than most standalone gas ovens in our best outdoor pizza oven roundup, and that’s the honest trade-off: you’re paying for the thicker stones, the adjustable vent, and Breeo’s build quality, not for a discount over a dedicated oven. It makes sense if you’re already invested in the Breeo ecosystem and want the best possible pizza result from the fire pit you own, rather than adding a second appliance to the patio.
3. Stanbroil Pellet Grill Pizza Oven Attachment — best for pellet-grill owners
Stanbroil Pellet Grill Pizza Oven Attachment
- Lists compatibility with 60+ pellet grill models, including Traeger, Pit Boss, Camp Chef, Green Mountain, Z Grills, Rec-Tec, and Smokin Brothers, per its Amazon listing.
- Adjustable support brackets adapt to different firebox widths instead of a rigid one-size fit.
- Includes a 13" cordierite pizza stone and a heat-capturing extension meant to speed preheat.
Pellet-grill owners are the most underserved buyers in this category — most pizza oven marketing assumes you’re starting from zero. This attachment assumes the opposite: you’ve already got a Traeger or Pit Boss doing double duty as a smoker, and it just needs a hood and a stone to add pizza to the rotation. The broad compatibility list is the selling point, but measure your firebox opening first — “fits 60+ models” still means checking your specific one.
4. Red Stag Pizza Oven Attachment — best budget pellet-grill pick
Red Stag Pizza Oven Attachment
- Sized for 90% of 20-inch diameter barrel-style pellet grills, per its Amazon listing — a narrower fit window than Stanbroil's.
- Includes a 14.6" x 14.6" ceramic pizza stone, larger than Stanbroil's included stone.
- Priced below most other inserts on this page, making it the entry point for pellet-grill owners.
If your pellet grill is a standard 20” barrel model — the most common footprint on the market — this is the cheapest credible way to add pizza to it. The trade-off for the lower price is a narrower fit window than Stanbroil’s adjustable brackets, so confirm your grill’s barrel diameter before ordering.
5. Pizzello Gusto 4-in-1 — best if you don’t own a fire pit or grill yet
Pizzello Gusto 4-in-1 Outdoor Pizza Oven
- Not technically an insert — a standalone 2-layer detachable oven that runs on wood, charcoal, or an existing gas stove/fire pit as a heat source, per its Amazon listing.
- Ships with a cordierite pizza stone, pizza peel, cover, and a cooking-grill grate, so there's no separate accessories run.
- Available in 12" and 16" sizes, priced roughly $90-150 depending on size and retailer.
If you searched “pizza oven insert” but don’t actually own a fire pit or pellet grill yet, this is the honest redirect: a genuinely standalone, multi-fuel oven cheaper than most of the inserts above, that doesn’t require you to own — or buy — a compatible base unit first. For shoppers set on a true standalone oven with more headroom, our best budget pizza oven guide covers the next tier up.
How to choose a pizza oven insert
- Confirm exact fit before buying. Solo Stove and Breeo inserts are sized to specific fire pit models; pellet-grill attachments list broad compatibility but still have firebox-size limits. Measure first.
- Check the total cost, not just the insert price. Breeo’s X30 owners need a separate $179 adapter; factor in any required accessories before comparing prices across brands.
- Expect slightly lower heat than a standalone oven. ~600-700°F stone temperatures are common for inserts versus 900°F+ for a dedicated gas oven — still hot enough for real pizza, just a couple more minutes per bake.
- If you don’t own the base unit, price out a standalone oven instead. A budget standalone like the Pizzello Gusto can undercut the cost of buying a fire pit plus an insert for it.
- Round out the setup. A pizza peel and an infrared thermometer matter just as much on an insert as on a standalone oven — the stone still needs to hit temperature before the first launch.
The bottom line
A pizza oven insert is the smartest upgrade path if you already own a fire pit or pellet grill: the Solo Stove Pi Fire is the easiest and best-value pick for Solo Stove owners, the Breeo Live-Fire Pizza Oven is the premium route for anyone chasing the best possible result, and Stanbroil or Red Stag bring pizza to a Traeger or Pit Boss you already fire up for smoking. If you’re starting from nothing, skip the insert math entirely and go standalone with something like the Pizzello Gusto. Whichever route you take, confirm the exact fit against your fire pit or grill model before you buy — that’s the one step every return on this category traces back to.
