Ooni Karu 2 Pro Review: The 16-Inch Multi-Fuel Flagship

The Ooni Karu 2 Pro is the successor to the much-loved Karu 16, and it sits at the top of Ooni's outdoor lineup as the brand's flagship multi-fuel oven. It cooks 16-inch pizzas, fires on wood, charcoal, or gas, and adds a connected temperature hub that the old Karu 16 never had. If you want one oven that can do authentic wood-fired flavor on the weekend and quick gas bakes on a weeknight, this is the model Ooni is steering serious home cooks toward in 2026.

This is an editorial review built from manufacturer specifications and published expert testing, not a first-person hands-on test. Our goal is to lay out what the Karu 2 Pro is, where it excels, where it compromises, and who should actually buy it.

What You Get

Out of the box, the Karu 2 Pro is ready to burn wood or charcoal; a gas burner (the Karu 16 and Karu 2 Pro Gas Burner) is sold separately if you want propane convenience. The headline specs are genuinely flagship-grade.

Key Specifications

Performance and Design

Heat and Cooking

A ~950°F ceiling is exactly what you want for true Neapolitan pizza, and published testing of this oven and its Karu 16 predecessor reports roughly 60-second bakes once it is up to temperature. The ~5.7-inch internal height and 17-inch-wide stone give you genuine room to launch, turn, and recover a 16-inch pie without fighting the door, which is a meaningful upgrade over smaller 12-inch ovens.

Multi-Fuel Flexibility

The multi-fuel design is the core appeal. Burning wood or charcoal delivers the smoky, leoparded crust that gas ovens can't fully replicate, while the optional gas burner gives you push-button heat for fast midweek cooking. That flexibility is why multi-fuel ovens command a premium; if you're weighing the trade-offs, our guide to gas, wood, and multi-fuel pizza ovens digs deeper.

Smarts: Ooni Connect

The big addition over the Karu 16 is the Ooni Connect digital temperature hub, with a front-mounted display and app connectivity that pushes ambient and probe readings to your phone. For a fuel-fired oven, where managing temperature is the hardest skill, real-time data takes a lot of guesswork out of the process. The probe also opens the door to more than pizza: roasts, breads, and low-and-slow cooks become far more approachable when you can watch internal temperature climb without lifting the door and dumping heat.

The Learning Curve

Multi-fuel ovens reward practice. Wood and charcoal demand that you learn fuel placement, airflow, and timing, and your first few bakes on live fire will likely include a scorched edge or a pale base while you dial it in. Gas shortens that curve dramatically, which is the quiet argument for buying the burner alongside the oven. The connected thermometer helps either way: it tells you when the stone has actually recovered between pizzas, which is the most common reason a second pie comes out worse than the first. If you're new to launching and turning, our walkthrough on how to launch and turn a pizza pairs naturally with this oven.

What It Cooks Best

At ~950°F the Karu 2 Pro is built for Neapolitan-style pizza: a 60-second bake, a puffed and leoparded cornicione, and a soft, foldable center. Dial the fire back and it handles New York-style pies, flatbreads, and even roasted vegetables or proteins in a cast-iron pan. The 16-inch capacity is the real unlock for entertaining, because you can cook a genuinely shareable pizza rather than a string of personal pies.

Strengths and Trade-Offs

Strengths: flagship 16-inch capacity, true 950°F wood-fired heat, genuine fuel flexibility, and a connected thermometer that helps you nail temperature management. The glass door with ClearView technology also makes it easy to watch the bake.

Trade-offs: it is heavy at ~63 lb and large, so it is not a grab-and-go oven. The gas burner is an extra purchase, which pushes the real all-in cost up. And at a premium price point, it is overkill if you only ever cook for one or two people.

How It Compares to the Rest of the Field

Against Ooni's own gas-only Koda 2 Pro, the Karu 2 Pro trades a little plug-and-play simplicity for the flavor and flexibility of live fire. Against the smaller Karu 2, it offers more capacity and the connected hub at a higher price and weight. And against premium rivals like the Gozney Arc XL, the Karu 2 Pro's headline advantage is multi-fuel versatility, where many competitors are gas-only. If wood-fired character is non-negotiable, that flexibility is the deciding factor; if you only ever want gas, a dedicated gas oven may be simpler. Our look at gas, wood, and multi-fuel ovens frames that choice in more detail.

Setup and Maintenance

Plan for a stable, heat-safe surface or a dedicated stand, since the oven's height and weight make a wobbly table a real hazard. Cleaning is straightforward: ash from wood or charcoal needs clearing between sessions, the stone self-cleans at high heat (carbonize residue, then brush it off cold), and a fitted cover protects the powder-coated body from the elements. As with any outdoor oven, give it clearance from walls and overhangs, and never move it while hot.

Who It's For

The Karu 2 Pro makes the most sense if you host pizza nights, want 16-inch capacity, and value the option to switch between live-fire flavor and gas convenience. If you mostly cook solo or want something you can move easily, the smaller 12-inch Karu 2 covers similar ground for less; see our Karu 2 vs Karu 2 Pro comparison to decide between them.

Frequently Asked Questions

Does the Ooni Karu 2 Pro come with a gas burner? No. It ships ready for wood and charcoal. The compatible gas burner is sold separately, so budget for that extra cost if propane convenience matters to you.

How is the Karu 2 Pro different from the old Karu 16? It is the direct successor and keeps the 16-inch, ~950°F multi-fuel formula, but adds the Ooni Connect digital temperature hub and refined glass-door tech. The Karu 16 has been discontinued, so the Karu 2 Pro is the current way to get this oven.

Is the Karu 2 Pro portable? Only loosely. At about 63 lb and roughly 32 inches tall, it is meant to live on a stand or sturdy surface. For tailgating or camping, a lighter 12-inch oven is a far better fit.

The Bottom Line

The Ooni Karu 2 Pro is a true flagship: 16-inch capacity, real wood-fired heat to ~950°F, multi-fuel flexibility, and smart temperature monitoring that lowers the learning curve. It is a premium, fairly heavy oven, and the gas burner is an add-on, but for entertainers who want one oven to do everything, it is among the strongest outdoor options in 2026.
