Key Features

There are major features of the Ooni Karu that you need to understand. These features will help you decide whether or not this is the pizza oven for you. They are:


When you pull this product out of the box, you may think it looks like a three-legged, long-necked, weird robot dog. The design is not so much aesthetic compared to others in the same price range.

Ooni Karu

The material used is mainly stainless steel. It looks shiny and sleek when you unpack it and take it to your desired outdoor pizza cooking spot. Once you start using it, you will notice the interior quickly gets black from the heat and smoke. The smoke and heat cause discoloration around the smokestack and firebox. Additionally, a patina may start to develop on the pizza stone.

Ooni Karu is designed to be used outdoors. As such, some patina may develop from weather elements depending on your location. The good news is snow and rain don’t affect the exterior and interior of the pizza oven.

Users have stated that it is “kind of” waterproof considering the interior and burned coal was left dry when it was snowing. Aside from tornados and hail, normal weather shouldn’t affect the product. Take note high winds during a rainstorm may push water into the oven. As a rule of thumb, covering a pizza oven during rainy and snowy weather conditions is recommended.

The oven’s opening is approximately 12 inches wide and 4.25 inches high. If you have a 12-inch wooden peel, it will fit perfectly. Unfortunately, the oven is limited to low-slung foods. This may be due to a low opening that causes fire to lick across the top of the oven.

You can use your cast iron cookware to roast hot dogs and bake cornbread. If you don’t have iron cookware that fits the Karu, Ooni sells cast iron cookware that perfectly fits into the oven. The back of the oven is where the fire is located. You can cook pizzas there, but you need to be careful to avoid burning the crust.

Setup Process

Assembling the Ooni Karu is easy-peasy. The smokestack cap easily sits on top, the smokestack twists off and on, and the legs fold out easily. The interior has a removable firebox designed to allow ash to drop through. This part just slides into place. A pizza stone is also included and it slips inside without any complications.

On the back, there is a door that allows you to access the firebox to load your coal or wood. There is a draft deflector at the very back. If it does not come installed, refer to the installation instructions manual. The product comes with an Allen wrench. You can use it to remove the deflector to create room for the optional propane-burning adaptor.

Preparing the oven to cook is also easy. Take the cap off the smokestack while leaving the baffle wide open. Then you can put the coal, wood, or both in the firebox. You can use either a torch or fire starter and you are good to go.


Ooni Karu

You can cook a great pizza in an instant. Starting a fire on the oven is no problem. However, some people found getting the interior of the oven to cooking temperature took some time. This may be because they were cooking during cold weather. You can use an infrared thermometer to check the temperature.

With time, you will get used to handling the fire as well as cooking pizza. If you want a longer burn, go for lump charcoal instead of wood. You can also use wood to create flames that will lick across the top of the oven’s cooking space. You can add it right before you put in the pizza.

Generally, it takes approximately 15 to 25 minutes to preheat the oven for cooking. Take note this estimate is when you cook during cloudy, windy, or cold days. On a warm summer day, the preheat time can be 15 minutes or less. Fortunately, Ooni Karu is well-insulated to ensure it holds its heat well.

According to the company, they state you can cook a pizza in a minute, they also suggest turning it in every 15 seconds for the best results. If you have cooked pizza before, may find it hard to believe. You can either use a timer or go for the more traditional “one-Mississippi, two-Mississippi” counting option.

If you are a beginner, you should start with plain cheese pizzas with basic red sauce. Once you get the gist of using the oven, you can move to more interesting topping options. Take note the more toppings you add the more complicated the cooking. As long as you move the pizza every 15 seconds, you should see progress. It is easy to adjust your cooking methods on the fly.

You can cook pizzas in 45 seconds if you move them toward the back of the oven. This is where the fire is located. This can work for simple pizzas such as plain cheese pizza. If you center the pizzas, 60 seconds is just the right duration for cooking topped pizzas.

Cooking pizzas at the front usually takes about a minute and a half for the pizza to get ready. This is determined by the toppings you use and the thickness of your crust.

Pizzas with vegetable toppings cook in a short time and keep some crunch. This may be a good option for vegans or if you just wanted a vegetable pizza. If you add sausage use small pieces if you want the interior to be fully cooked. Pre-cook the sausage if you want to use large pieces.

You don’t need to always move your pizza from the back to the front and vice versa. You can control the temperature using the baffle in the smokestack. When it is wide open, Ooni Karu burns clean, fast, and hot. Closing the baffle creates more smoke and slows the cooking.

The fuel you use is also a serious consideration. If you only use lump charcoal, you won’t get flames on the top of the oven. Keep in mind regular charcoal is not recommended. Lump charcoal offers plenty of cooking heat with the downside of not getting intense top heat.

There are plenty of fuel combinations or airflow and fuel to adjust the temperature for cooking different foods. For pizza, fast and hot is easy to achieve with stellar results.


The weight is light enough to let you move it around without breaking your back. It’s easier if you remove the smokestack, fuel door, and front door. This move is recommended to avoid dropping them in transit. The baking stone can also be removed to lighten the load. You can purchase a carrying or cover case to make the oven more portable.

Ooni Karu

Storage and Care

Temperatures of 730 degrees to 850 degrees in the middle of the stone are recommended for making the perfect pizza. The same temperature range is great for making quesadillas and tostadas.

Use a lower temperature range especially if you are making cornbread using a cast iron pan. You may notice the cornbread may be slightly darker at the top compared to if you cooked in an oven. For a lighter top, consider covering it with foil.

After some time, your Ooni Karu may start looking used. This should not be a concern for any outdoor oven considering it is not a display product. The interior does not require thorough cleaning in between uses. To clean, wait for the oven to cool down.

Once cool, remove the fuel box and empty it before you replace it. Debris on the stone can be brushed off before you cook your next pizza. Sometimes there is food residue stuck on the stone from dripping sauce or cheese. The manufacturer recommends scrapping it off. Let the product burn at high heat to ensure the remaining sauce or cheese is incinerated.

If you feel you need to clean the stone thoroughly, remove it and rinse it clean. Avoid using soap on the stone. Ash on the inside can be wiped away and the inside can be scrubbed if you see a lot of smoke buildup.

If you don’t plan on using the oven for a long time, move it indoors. It will ensure you keep crawlies like spiders from making a home in the oven.


The cost of all Ooni Karu ovens is moderately expensive. If you compare it with a permanent brick oven, the cost is not as high. The cost may be high considering the oven is designed to only cook pizzas. If you love cooking pizza regularly, then the oven is a good investment.

Best Wood Fired Alternative – Ooni Frya

The positive feedback we came across about Ooni Frya makes it our choice for the best wood-fired Ooni Karu alternative. The majority of people who have used it compliment the delicious smoky flavor you get when you cook pizza. Even though there is some negative feedback about the product, it’s mostly about the finish. The general feeling is the finish should be improved.

Ooni Karu

Ooni Frya can go to more than 900 degrees Fahrenheit in a quarter of an hour or less. These temperatures are achieved using only wood pellets. At such intense temperatures, you can cook your pizza in a minute or less. The fast-cooking capability means you use less energy and save on fuel costs.

Best Gas Alternative – Pizza Party Ardore

Ardore has great reviews when it comes to the best outdoor gas pizza oven. This is why it is our choice for a gas-powered alternative to the Ooni Karu. For starters, the product is made in Italy which says a lot about its quality and authenticity. Unfortunately, it is not easy to get it to the United States. You have to ship it from Italy and wait for some time for it to arrive. Additionally, the shipping costs may be a demerit for some people.

Ooni Karu

Biscotto is a famous stone renowned for its capability of cooking pizza at approximately 850 degrees Fahrenheit for up to a minute and a half. Unlike other stones, Biscotto can cook pizza at this temperature for the said duration without burning the pizza’s bottom. The reason the stone maintains this great feat is its alluvial clay.

The stone is made by Italian artisans in Naples who don’t use any machinery. Naples is the birthplace of the popular Neapolitan pizza. Take note Biscotto is not part of the pizza oven package. You need to purchase it separately. Instead, the oven comes with Saputo stone. It’s 1.2 –inches thick meaning it has a superior capacity to retain heat. This results in better cooking and superb pizzas.

Ardore has a cooking area of 15.75 inches by 15.75 inches. This is a large cooking surface allowing users to better manage their pizzas as they cook. A wider opening is one of its great features. Such an opening makes accessing the peel a breeze.

This pizza oven comes with a 2-year warranty covering components and materials that manifest construction defects. Unfortunately, Saputo stone is not covered under the manufacturer’s warranty. With the capability of reaching 550 degrees Celsius (1022 degrees Fahrenheit), expect to get well-melted toppings and a crunchy crust.

According to some users, the design is not stylish and is too basic. This shouldn’t be an issue if the aesthetics of a pizza oven is not a determining factor in your buying decision. Additionally, some users find it to be pricey considering the price and shipping costs. If you are not on a budget, then this should not be an issue.


  • Reaches some of the highest pizza cooking temperatures
  • Great warranty
  • Large interior for cooking large pizzas
  • Stone is thicker than what you find in other pizza ovens
  • Uses high-quality Saputo stone


  • Can only be shipped from Italy
  • High purchase and shipping cost

Pizza Oven Buying Guide

Outdoor ovens are available in a variety of designs and styles. You need to know the features you need when you plan on buying one. The following is a buying guide with features you need to consider before you purchase an outdoor oven.


There are two main types of fuel for outdoor ovens. Wood is the most popular and traditional choice. Gas is increasing in popularity and seems to give its wooden counterpart a run for its money.


The basic of a wood-fired oven is it involves the burning of timber. It is a simple and straightforward process. Keep in mind you can’t use any type of wood or timber to fire up a wood outdoor oven. For example, wood chippings and hardwoods are fine. Avoid treated or colored wood as the chemicals may end up in your pizza.


These types of ovens are easier to control and light. You don’t have to worry about lighting your fuel and ensuring there is always enough in the oven. Gas-fired pizza ovens don’t require a lot of attention during the cooking process. This may be the reason why they are more popular in commercial spaces.


Other Considerations

There are other considerations you need to think about when you are buying an outdoor oven. They include:

  1. Materials – Usually, stainless steel, clay bricks, and concrete are the common materials used to make an outdoor oven. The material you choose determines the durability and effectiveness of your outdoor pizza oven.
  2. Style and Size – The size and style need to be considered when you are buying a pizza oven. Maybe you are not concerned with the style per se. Take note the style impacts the benefits and cooking purposes of the product.
  3. Residential or Commercial – Although obvious, not all outdoor pizza ovens are fit for commercial purposes. These items differ in material and size. For starters, if you are looking for a commercial oven for a restaurant or outdoor eatery, consider the efficiency of the materials used and the size of the dome.
