If you’ve ever dreamed of putting dinner on autopilot, the Breville Joule Four Air Fryer Pro just might be the gadget you’ve been missing.

It’s a multifunctional oven that will help you streamline a variety of cooking projects from the comfort of your countertop and has more features than a traditional basket-style air fryer.

Pro Breville Joule Oven Air Fryer Features

A multifunctional countertop oven

Of all the air fryers I’ve tested, the Breville Joule has by far the most versatile feature. It can work as a standard convection oven or an air fryer, and it performed all cooking tasks well in my testing. The oven is spacious and large compared to a standard basket-style fryer, so it can fit a platter of appetizers, a few pieces of toast, or a whole 14-pound turkey. Thirteen functions include toast, bagel, bake, air fry, broil, roast, pizza, cookies, proof, reheat, slow cook, keep warm, and dehydrate. It has eight rack positions so you can get consistent, targeted results for the type of food you’re cooking, making it more versatile than other air fryers I’ve tested. This oven is a fantastic option for someone looking to save space by replacing multiple gadgets with one do-it-all machine.

The Joule has some advanced features, but it’s still great for everyday use. I have used this oven to fry chicken wings and fries, but also to bake cookies and muffins. In addition to dedicated testing, I’ve also used it to make toast and reheat bagels on a daily basis. While some multi-function machines advertise unique functions that really produce the same results, I was able to identify the differences between baking, toasting, and air frying with the Joule during my testing. The chicken wings and fries came out evenly cooked, with moderately crispy skins and an evenly browned color. Cookies and muffins bake as they would in a traditional oven, with slightly domed tops and moist interiors. Toasted foods like bagels and English muffins came out soft inside with crisp, crisp edges, just as they would have if cooked in a traditional toaster. Although it’s a big machine which can seem complicated, I found the Joule to be easy to set up, understand and use.

Simple and easy to use

Considering the fact that this oven has 13 functions, it’s surprisingly easy to use. The digital control panel is simple, so you can easily switch between different features and clearly see which one you have chosen. You can independently set the time and temperature regardless of the preset you have chosen. A handy light lets you easily see what’s going on inside, and the grates automatically extend when you open the door to flip or remove food. This means that there is no need to put your hand and arm in the hot oven.

However, I’ve noticed that this oven is a little harder to clean than some others – and that makes sense, as it involves more than just a non-stick coated basket. Food can spill out of the rack, which makes cleaning the inside of the oven a little tedious. Be careful when air frying juicy or fatty foods like chicken wings – we noticed that when moisture dripped down and hit the heating element at the bottom of the oven, it caused smoke. For best results, make sure there is a baking dish or baking sheet under the air fry basket. This way any dripping juices will hit the tray rather than the heating element.

An automated experience for easy dinners

Perhaps what sets this oven apart the most is its ability to create a fully automated cooking experience in addition to crisping up snacks and leftovers. With the Joule app, you can access chef-approved recipes and tips and tricks while cooking. Best of all, it’s voice assistant compatible, so you can pair the oven with your Alexa or Google device. For easy, hands-off cooking, you can even set the oven on autopilot, which means it will seamlessly cycle through different time, temperature and cooking functions as needed.

The app is easy to use. Simply download it and pair it with your oven via Bluetooth. Once set up, you can scroll through a wide range of dedicated recipes, like Cauliflower Shawarma with Spicy Tahini or Honey Mustard Chicken Thighs with Roasted Sweet Potato Salad. After selecting a meal, simply prepare the ingredients and tools according to the steps outlined in the recipe, then press the autopilot button on your phone. Although you have to manually press start the oven, it will then cycle through different temperatures, functions and cooking times completely independently. This means you can go from preheating to broiling without pressing a button.

My knowledge

With years of professional experience in restaurant cooking and home cooking, I am always on the lookout for products that will make cooking easier and more efficient. I use my Culinary Arts degree from the Institute of Culinary Education to create thoroughly tested product reviews that help shoppers make more informed purchasing decisions. My product reviews can be found at Food & Wine,, Real Simple, Better Homes & Gardens, and more.

How does it compare?

In my test of best air fryers, this product has proven to be one of the most versatile options. It can bake a pizza, roast a chicken or heat up a bagel. I loved how much food it can hold – it’s 21.5 inches wide, 17.3 inches deep, and 12.8 inches high – and the fact that I could control it from my phone. This oven is also one of the most efficient I’ve tested: eight rack positions also allow you to cook multiple layers of food at once. More so, I love that despite the added features, it’s still very easy to use and simple to understand.

The Joule is a great option for someone looking for an all-in-one oven, but it can’t match the same air frying capabilities as the Ninja Max XL Air Fryer or the 6 Quart Instant Vortex Air Fryer, both of which are basket-type machines. The cookies cooked perfectly, but we found they didn’t produce the same ultra-crispy results when used as a dedicated air fryer. Plus, it’s considerably larger, so it takes up more counter space and would be harder to store.

The Joule is the evolution of Breville Smart Oven Pro Air Fryer, and includes some additional accessories and new features as well as application compatibility. Compared to the Smart Oven Air Fryer Pro, the Joule has an adjustable grate, a broil rack, a feature that saves your most used cooking shortcut and of course pairs with the Joule app . While the Air Fryer Pro packs a punch with 13 functions, the Joule offers Breville’s latest technology if you want the brand’s smartest countertop.

How I Tested the Best Air Fryer

To test the Joule, I considered factors such as size, convenience and functionality. The Joule is one of the largest ovens I’ve tested – I made note of how the large countertop footprint would affect storage and cleanup. To determine functionality and versatility, I put it through three culinary tests. I fried common foods in an air fryer like French fries and chicken wings to see how well and consistently the oven could circulate hot air. I examined the color of cooked fries and rated how golden and crispy they were after cooking. I also considered the grease and dripping chicken juices and was careful about any smoking or flare ups. To compare cooking power, I looked at both the skin color and texture of the chicken as well as the texture of the meat, to make sure the chicken was crispy, but also juicy and perfectly cooked. Finally, I baked some chocolate chip cookies and tested how crispy or moist they were.

To complete the tests, I cleaned the oven and all the accessories according to the brand’s instructions and observed how easy or difficult it was to clean. Throughout the process, I took note of the control panel and observed how intuitive or counter-intuitive the machine was.
