Reviewers describe the Ooni Karu 2 Pro as a versatile workhorse for outdoor kitchens, praised for its ability to switch between wood, charcoal, and gas fuels. While the Bluetooth thermometer and spacious interior are highlighted as major benefits for cooking large pizzas and meats, users note that the oven takes significantly longer to heat up than the manufacturer claims. The heavy weight and need for separate accessories like an infrared thermometer for stone temps are common drawbacks. It is best suited for dedicated outdoor cooks who value fuel flexibility over portability.
Full review
Build Quality and Design
The Ooni Karu 2 Pro arrives in a substantial box weighing roughly 83 pounds, signaling a dense, heavy-duty construction that reviewers consistently praised for its solidity. Popular Mechanics noted that the oven feels truly solid, a quality they prioritized over portability, though they warned that lifting it likely requires two people due to its cumbersome weight. Once assembled, the unit weighs approximately 60 pounds and stands on three legs that elevate the cooking chamber off the surface. Pala Pizza’s Kevin Hansen described the assembly process as simple and manageable for a single person, involving attaching the thermometer, inserting the Cordierite stones, connecting the glass door, and locking the smoke stack into place with a single clockwise turn. The interior offers a 17-inch wide cooking surface with nearly 5.5 inches of vertical height, providing ample room for 16-inch pizzas, steaks, or larger cuts of meat without feeling cramped.
Multi-Fuel Versatility and Setup
The defining feature of the Karu 2 Pro is its ability to switch between wood, charcoal, and propane, though this flexibility comes with a caveat: the gas burner is sold separately. UofMTiger emphasized that while the multi-fuel capability offers great options, buyers must factor in the additional cost of the propane burner if they intend to use gas. Swapping between solid fuel and gas is straightforward, requiring only the loosening of two screws to exchange the fuel tray and hatch for the burner assembly. For wood or charcoal cooking, a metal tray sits at the back of the oven to hold the fuel while catching ash, and a removable rear hatch allows for easy refueling during the cook. Serious Eats highlighted that the baffle can be opened or closed to control airflow, which is crucial for managing temperature depending on the fuel source or desired cook time. This modularity makes it a true workhorse for outdoor kitchens, allowing users to experiment with different heat profiles without buying multiple ovens.
Heating Performance and Speed
Ooni claims the Karu 2 Pro reaches 950 degrees Fahrenheit in 15 minutes, but real-world testing suggests this timeline is optimistic, particularly in colder conditions. Pala Pizza’s Kevin Hansen recorded a heating time of 30 to 40 minutes when using the gas burner on full flame, noting that the stone started at a chilly 44 degrees Fahrenheit. He suggested that a roaring wood fire might heat faster, but he did not test that specific scenario due to variable conditions. Popular Mechanics echoed these findings, stating that while the oven reaches peak temperatures fast, their initial wood-fired attempt only hit 525 degrees Fahrenheit due to user error with damper control and wood moisture. However, once properly managed, the oven delivers blistering heat. UofMTiger reported that with gas, the oven can scorch pizzas if left at 100 percent heat, indicating intense thermal output. Serious Eats noted that the Karu 12, a smaller sibling, preheats in 20 minutes with wood, suggesting the larger Pro model requires more time to bring its massive stone up to temperature.
Cooking Results and Heat Distribution
The heat distribution in the Karu 2 Pro requires a learning curve, as the flame source is located at the back and rolls up the ceiling toward the front vent. Pala Pizza observed that this rear/top-down heat distribution means the first pizza often comes out more well-done than intended until the cook adjusts their technique. The recommended method involves launching the pizza, lowering the flame to firm up the bottom, and then cranking the heat back up to brown the top while rotating with a turner. UofMTiger experienced similar issues, noting that their first few pizzas were scorched because they failed to modulate the heat. However, once mastered, the results are impressive. Popular Mechanics reported achieving pizzeria-worthy pies with bubbly cheese and perfectly charred crusts in just 90 seconds using propane. Pala Pizza praised the leoparding achieved with the gas burner and the nice color on the crust when cooking with wood, describing a sausage pizza as turning out wonderfully with a crisp undercarriage and puffy soft interior.
Smart Features and Accessories
The Karu 2 Pro includes a digital thermometer with Bluetooth connectivity, allowing users to monitor oven temperature from their phone. UofMTiger found this feature very nice for prepping pizza inside while the oven heats up outside, but cautioned that it does not accurately reflect the stone temperature. Both UofMTiger and Pala Pizza agreed that an infrared thermometer is almost a necessity for checking the actual stone heat. The Bluetooth device also has an input for a food thermometer probe, which UofMTiger noted would be handy for cooking large cuts of meat like chicken, though they had not tested it yet. Pala Pizza pointed out that there is no probe to measure the pizza stone itself, reinforcing the need for external tools. Additionally, users reported needing heat-resistant gloves and a bristled brush for cleaning, with UofMTiger recommending the Aolso Pizza Oven Brush for maintaining the stone. The lack of included accessories like the gas burner and infrared thermometer means the total cost of ownership is higher than the base price suggests.
Where It Falls Short
Despite its high praise, the Karu 2 Pro has notable drawbacks that reviewers consistently highlighted. The most frequent complaint is the separate purchase requirement for the gas burner, which Popular Mechanics found annoying given the oven’s $849 price tag. UofMTiger also noted that the pizza turner they bought was not dishwasher friendly, a minor but frustrating oversight for a premium product. The learning curve for heat management is steep; both UofMTiger and Popular Mechanics reported initial failures with scorched or undercooked pizzas due to improper flame modulation and damper control. The oven’s size and weight make it less portable than advertised; Popular Mechanics described it as bulky and awkward for one person to move, and UofMTiger mentioned needing a dedicated cart like the Feasto Pizza Oven Cart to manage its length and weight. Furthermore, the Bluetooth temperature reading can be misleading, as it measures air temperature rather than stone temperature, potentially leading to premature cooking attempts.
Who It's Best For
The Ooni Karu 2 Pro is best suited for serious home cooks who want the flexibility to switch between wood-fired authenticity and gas convenience without buying multiple ovens. Shoppers who prioritize build quality and are willing to invest in additional accessories like the gas burner and infrared thermometer will find this a strong fit. It is ideal for those with a dedicated outdoor kitchen space, as its weight and size make it impractical for frequent moving. Users who enjoy experimenting with different fuels and are patient enough to master the heat distribution dynamics will appreciate the versatility. However, those seeking a plug-and-play experience or a truly portable oven for tailgating should look elsewhere. Beginners might find the learning curve steep, so Popular Mechanics recommended starting with propane to acquaint oneself with the oven before attempting wood-fired cooking. Ultimately, it is a premium choice for enthusiasts who value performance and durability over convenience and portability.
Value at This Price
At $849, the Ooni Karu 2 Pro sits at the high end of the consumer pizza oven market, competing with models like the Gozney Dome and Alfa NANO. Serious Eats positioned it as the best high-end multi-fuel Ooni option, distinguishing it from the more budget-friendly Karu 12 and the mid-range Karu 2. While the base price is steep, the value proposition improves if the user intends to utilize both solid fuel and gas capabilities, effectively replacing two separate ovens. However, the necessity of purchasing the gas burner separately adds to the cost, which some reviewers found frustrating. Popular Mechanics and UofMTiger both noted that the total investment, including accessories like carts, thermometers, and burners, can quickly exceed the initial price tag. For those who cook frequently and value the ability to switch fuels, the Karu 2 Pro offers a compelling package. But for casual users or those on a tight budget, the Karu 12 or Koda series may offer better value without the premium price and complexity.
