What experts didn't like
"I was [initially] confused by the number of attachments. More pictures [in the manual] would have helped."
It’s on the heavier side at 25.4 pounds and its dimensions are 22.3 x 19.3 x 16.3 inches.
- Easy Kitchen Appliances
The manual does not state that the trays are dishwasher safe.When making chicken I did find there was a lot of clean up, especially on the oven door. When I open the oven to flip the chicken, the air fryer basket sits directly over the door when you pull it out.

An Overview On Convection Ovens

If you want a perfectly browned turkey on Thanksgiving or an evenly cooked ham on Christmas, a convection oven is what you need. Let’s look at how a convection oven works and the best applications for it in your cooking.

The difference between a traditional oven and a convection oven is the airflow cycling that the convection features. The hot air is blown around the food and vented out in a convection oven. This creates a perfectly dry heat that will crisp the outside without drying the inside of your food. Like a traditional oven, a convection oven still hosts heating elements that produce the heat, so technically it has radiant heat and forced hot air as cooking sources. This system is very efficient, and you may find you need to adjust the temperature and cooking time of your recipes. It cooks faster and more evenly than a traditional oven.

“It’s precision cooking and yes, it makes a huge difference,” says our expert Vicki Liston, host of the award-winning home improvement show “On the Fly…DIY.”

“Have you ever cooked something in the oven, a microwave, or a traditional toaster oven and had the item cook unevenly? Or experienced ‘hot spots’? A convection oven solves these cooking irritations,” says Liston. “It preheats faster than a traditional oven and uses less power to run. In the summer months, it makes cooking much more bearable as it doesn’t heat up your entire house during operation.”

When you first start using a convection oven, it’s smart to pay close attention to the food while it’s cooking. There are certain foods such as breads and cakes that need time to rise that don’t do well in a convection oven. If you are cooking a recipe for the first time in the oven, try decreasing the temperature by 25 degrees from the suggested temperature. This will ensure thorough cooking without burning.

Another thing to remember when cooking with a convection oven is the type of pan you use for your food. Shallow dishes do best with convection because it increases the surface area that the heated air touches. Many baking dishes have been adapted for convection purposes but consider updating your bakeware for the best results.

Some convection ovens feature sensors and presets for different foods. The presets should be used as guidelines and can be reliable with some foods. Sensors are not always reliable but can help you gauge how long and what temperature to cook certain foods when you first start out. They should also be used as a guide. Another handy tool to have on hand when first starting out with a convection oven is a thermometer probe. This will come in particular use when cooking meat dishes. Remember to always keep an eye on food in a convection oven since it cooks much faster than a traditional oven.

There are all different styles of countertop convection ovens. From a drop-down door in the front, like the Breville Smart Convection Toaster Oven, to a French-door opening like the Oster Convection Countertop & Toaster Oven you will find a style that works in your kitchen. The Cuisinart Stainless Steel Convection Toaster Oven and DeLonghi Stainless Steel Convection Oven feature stylish knobs for programming the settings. They are all designed with large digital displays so you can see exactly how long and what temperature you’ve set it to.

DYWM Fun Fact

Open fires were the ovens of old but cooking devices have evolved quite a bit since those prehistoric times. The first convection oven was invented in 1914 by William Hadaway, but was only used for personal use and not offered to the public. Years later, in 1945, the Maxson Whirlwind oven became the first convection oven sold on the market.

The Convection Oven Buying Guide

  • According to Liston, convection ovens are “ridiculously versatile.”
    “You could replace several kitchen appliances by getting one,” says Liston. “Many people consider the amount of counter space taken up to be a drawback. However, if you didn’t need an air fryer, a toaster, a microwave, a dehydrator, a slow cooker, and even a plate warmer, would you make the switch? In fact, it can save you space in the long run!
  • Adjust temperatures and times of recipes when first starting out with your oven.
  • Baked goods that need to rise will not do well in the convection oven.
  • Meats that need crispy exteriors will do great in the convection oven.
  • Remember to leave plenty of space around your convection oven for the best ventilation.
