LG’s new TurboCook™ Speed Oven

  • Get the hustle of a microwave with the quality you expect from a convection oven. Bake bread, whole chickens, potatoes, pizzas and more–no preheating required. With speeds 2 to 4 times faster than a traditional oven, you’ll have more cooking flexibility and more time to enjoy your meal.

Cook with Confidence

  • True Convection delivers precise heat for crisp, delicious food. Bake with the greatest of ease with LG’s True Convection oven. Our convection technology evenly distributes continual precise heat so food is delicious on the inside, and crisp on the outside.

No Preheating, Up to 20% Faster Cooking

  • When you’re craving the thrill of the grill but Mother Nature has other ideas, you can still achieve that characteristic seared flavor with LG’s Infrared Heating™ system. The infrared heating element locks in juices while cutting up to 20% off your cooking time–with no preheating required.

10 Minutes. 1 Spotless Oven.

  • Got 10 minutes? LG EasyClean® brings you the fastest oven-cleaning feature yet. In three easy steps and 10 quick minutes your oven can be sparkling clean, without strong chemical fumes or high heat. Simply spray the oven interior with water, press EasyClean® and then in 10 minutes, quickly wipe away any leftover grime.

Steam Cook Nutritious, Tasty Dishes

  • Bring one of the healthiest ways to cook to your kitchen. Steam cooking evenly distributes moisture and pairs perfectly with the true convection system for food that’s golden outside and tender inside. The refillable water reservoir doesn’t require plumbing, making installation that much easier.

Sleek and Practical Design

  • Intuitive SmoothTouch™ glass controls not only look sleek but makes operating your oven a snap with just a touch of your finger. Best of all, they have been designed with practicality in mind – the smooth surface easily wipes clean.

Think of the Possibilities

  • LG wall ovens featuring SmartThinQ® technology let you check on dishes from the comfort of your couch by monitoring cooking mode and remaining time using the LG SmartThinQ® smartphone app – which you can use to activate features through simple voice commands. It even works with the Google Assistant, Amazon Alexa, SideChef and Innit.

Multiple Presets Make You a Pro

  • Take the guesswork out of cooking. Let the preset cooking functions take over when you need to defrost, reheat, melt and more. With 50 options to choose from, we’ve got you covered from frozen to fresh, apps to entrees.
