LG LSGL6337F 6.3 Cu. Ft. Smart Slide-In Gas True Convection Range review: this cooker does it all

Once this advanced and innovative range is in your kitchen, you won’t need your microwave, air fryer, convection oven, and other single-use appliances again.

The 6.3 cu. ft. Smart Gas Slide-in Range with InstaView® ProBake Convection®, Air Fry, and Air Sous Vide’s wide variety of abilities might even take you a while to fully grasp, as it has so many capabilities that you will likely have to spend time getting to know each other.

I was immediately impressed with the range's look, which resembles something you’d find in a professional chef’s home kitchen—before you open it to reveal a shiny royal blue inside the door and oven. The fifth burner with a skillet option is a game changer for any pancake or sandwich fan, providing significant additional cooking space on the stovetop.

One of the most unique features is a knob to turn the oven itself on and off near where the stovetop burners are. This takes some getting used to, and as someone with little kids, I wasn’t a big fan of their access to that.

Overall, the range is innovative and has comprehensive abilities that you’ll come to appreciate more with each unique meal you cook on it. For more, take a look at some of the best gas ranges in our guide.

LG LSGL6337F 6.3 Cu. Ft. Smart Slide-In Gas True Convection Range: Setup

The delivery service brought the range in, and I immediately noticed its unexpected blue lining inside. It’s quite pretty and hides unsightly dirt, stains, and marks that a typical oven might show more easily. The outside is black or “print-proof” stainless steel, which hides marks slightly better than other options. However, I wouldn’t call it completely print-proof.

The setup wasn’t as involved as I’ve seen with other ranges, and the installers were finished in just a few minutes. They simply slid the range into place, plugged it in, and tested it out. Everything was seamless. However, due to the product size, it did take two people.

I first noticed how much higher the burner grates were than my previous gas oven, how large the center burner and cast iron-style flat pan could cover it, and how it didn’t smell as gassy as my last range.

There were quite a few protective stickers that don’t come off in one piece, and better markings of where those are would be helpful because I cooked with some on before I realized they were there.

LG LSGL6337F 6.3 Cu. Ft. Smart Slide-In Gas True Convection Range: Design & Features

If there’s one thing that stands out about this range's design, it’s the blue interior of the oven! This unique design element is unexpected and gives it a fun, retro vibe. With its easy-to-wipe-down interior and seven various rack settings, the oven leaves you feeling like you just might be able to be a professional chef.

I also really liked the various oven heating options, including its ability to be a convection oven. When I’m short on time, it’s been a great alternative to traditional baking for getting a meal on the table.

The overall design of the oven portion of this range is pretty user-friendly, but I admit I’m not as crazy about the knob control for the oven, especially as a mom of four curious boys. While the knob doesn’t automatically turn on the stove without pressing the start button along with it, it does make me a bit more nervous at its accessibility to young hands in my busy kitchen.

The stovetop has five burners, with one burner in the middle that has been great for making grilled cheese sandwiches alongside various soups one night for supper. I love having that middle burner going with a griddle/flat top and still using the remaining four burners without losing space for other cooking needs.

Just like the oven knob, I’d like for the stovetop knobs to be a bit less accessible or easily turned on. The knobs don’t snap in place like my previous ranges have, so it leaves me double-checking a lot to make sure that no gas is leaking unintentionally. The graphics for which knob goes to which burner/oven could also be a bit clearer for users, especially if you’re a bit taller than I am. I often find myself having to back up to have a better look at which burner knob I’m operating.

LG LSGL6337F 6.3 Cu. Ft. Smart Slide-In Gas True Convection Range: Performance

- 8 minutes to preheat oven

- Keep warm after cooking function

- Sync mechanism between over-the-range micro and range

- Thin Q App: offers smart features and care alerts

While this might not seem important, it is when it’s as easy as knocking on the window. With just two knocks, you can see into the oven and check how crisp your chicken is coming out of the air fryer or how long your muffins still need to be. I didn’t use the light on my previous oven because it didn’t have this incredible option, which kids also loved. It helped them learn to cook safely without opening the oven to check on food.

I compared how long it took me to boil bow-tie pasta on my stove versus a friend’s older oven. It was around 3 minutes quicker, at just over 5 minutes, to cook a box of pasta in around 4-5 cups of water versus around 8 minutes at her house. This can likely be attributed to the stove's quick boil function, with the option to heat things more quickly, so spaghetti night doesn’t have to wait.

I also “raced” my friend with an older oven to see how quickly this one would reach 350 degrees in a preheating competition. Notably, this oven shows specific progress in preheating, while theirs does not. It took seven minutes to preheat to 350 degrees with this oven and closer to 10 for her oven. Again, this saves time and efficiency.

If you are a grilled cheese connoisseur, you know it takes the right pan to make the perfect sandwich. I made three at once, using the middle burner and the cast iron skillet-style griddle, a long rectangular pan that easily comes on and off. While some of the sandwiches closer to the burner did cook more quickly than others, overall, it was a positive experience with crunchy but not burnt sandwiches. I’ll just have to get used to positioning them where the burners are or aren’t.

LG LSGL6337F 6.3 Cu. Ft. Smart Slide-In Gas True Convection Range: Care & maintenance

One of the things I was most impressed with was the ease of cleaning this range. The stovetop grates come apart in three pieces so that you can immerse them in the sink for washing. While I did struggle to put them back together after washing them, it’s nothing that LG couldn’t make a bit easier, with some minor markings letting you know which piece goes where.

I also liked that I could remove the burner for easy cleaning and that there were no weird edges along the stovetop where food could get trapped.

Maintaining the stovetop requires some elbow grease, as it doesn’t use the same wipeable material that LG is known for in other appliances.

The oven comes with two cleaning options: EasyClean, completed by the stove in 10 minutes with a little bit of water you spray on the interior, or a full self-clean option that allows for a deeper clean (and a bit more work from you). As someone a bit intimidated and avoidant of all the cleaning chemicals it seems you can use for ovens, spraying with water and wiping it down was a welcome and simplistic relief, which made me want to clean it more often. That prevented build-up and was helpful in the long run.

LG LSGL6337F 6.3 Cu. Ft. Smart Slide-In Gas True Convection Range: Price & Value

This range can be purchased through the LG website for $1999. It can also be purchased through major retailers such as Lowe’s, Home Depot, and Best Buy. The product does seem to be in and out of stock, so if one retailer doesn’t have it, you might be able to find it at another.

Though it might be a hefty price for some, it seems to replace numerous other appliances, such as toasters and air fryers, confection ovens, and microwaves. I’m impressed with its versatility, which makes it worth the price.
