If your kitchen counter is already crowded with a bulky air fryer, a separate convection oven, and a stack of takeout menus for the nights you don't feel like cooking, the Granite Stone Glass Air Fryer XL is trying to solve several problems at once. This is a 16-quart, all-glass air fryer that Granite Stone markets as the largest glass air fryer currently available, and after reviewing the official product listing, specs, and included accessories, here is an honest look at what it actually offers.
Most air fryers rely on a single fan-driven convection element to circulate hot air. Granite Stone's approach is different: the Glass Air Fryer XL combines three separate cooking technologies — halogen, convection, and infrared heat — inside one glass bowl. The idea is that layering these heating methods creates a more even, intense cooking environment, which in theory helps foods like chicken wings, fries, and vegetables crisp up on the outside while staying tender inside, without needing to toss a bag of oil into the mix.
Because the cooking chamber is made of tempered glass rather than a coated metal basket, you can actually watch your food cook in real time through the lid, which is a genuinely useful feature if you've ever ruined a batch of fries by guessing when they were done. It also means there's no non-stick coating to worry about scratching or flaking over time — the brand notes the unit is designed to be Teflon-free and non-toxic, which matters to anyone trying to cut down on PTFE and PFOA coatings in their cookware.
At 16 quarts, this is a genuinely large appliance — closer in size to a countertop convection oven than a typical 4-6 quart basket-style air fryer. Granite Stone leans into that with marketing that suggests you can cook an entire holiday-sized meal in it, and with the included expansion ring, there's enough vertical room to fit taller dishes, whole roasts, or multiple layers of food at once.
Each unit ships with the 16-quart glass bowl, a stand, two stainless steel cooking racks, rack tongs for safely pulling hot trays out, the expansion ring for extra capacity, and a recipe book to help you get started. The control panel houses the halogen heating element, the fan, a built-in timer, and a mesh basket insert for smaller or looser foods like fries or shredded vegetables that would otherwise fall through the racks.
The two-rack, multi-level design is meant to let you cook more than one dish simultaneously — for example, protein on the lower rack and vegetables on the upper one — which can be a real time-saver on busy weeknights compared to running multiple rounds through a smaller air fryer.
Air fryers can be a pain to clean, especially ones with textured non-stick baskets that trap grease in the corners. Granite Stone addresses this two ways: a built-in self-clean mode that runs a cycle to loosen residue after cooking, and removable glass and metal parts that are dishwasher safe. For anyone who has hand-scrubbed a basket at 10pm after dinner, both of these are meaningful quality-of-life improvements.
At the time of writing, the Granite Stone Glass Air Fryer XL is listed at $129.99, discounted from a $169.99 regular price, which works out to roughly 24% off. The listing also references an additional $30 instant coupon applied at checkout, and the product ships with free shipping. The listing currently shows 187 customer reviews on the official site. It's available in three colorways: Black, White, and Silver, so there's some flexibility to match your kitchen's look.
Compared to premium basket-style air fryers from brands like Ninja or Instant, $129.99 for a 16-quart unit with three heating technologies, two racks, an expansion ring, and dishwasher-safe glass components is a competitive price point, particularly if you were already considering both an air fryer and a small convection oven and would rather consolidate into one appliance.
This air fryer makes the most sense for households that cook for more than one or two people, or for anyone who's outgrown a compact basket-style model and is tired of cooking in multiple batches. If your kitchen counter space is tight, it's worth noting that a 16-quart glass appliance with an expansion ring is not a small footprint — measure your available counter and cabinet clearance before ordering, especially if you plan to store it rather than leave it out permanently.
If you mainly cook for one person or rarely use appliances that take up significant counter space, a smaller basket-style air fryer may still be the more practical choice. But for larger households, meal preppers, or anyone who wants to bake, roast, and air fry in a single non-toxic glass chamber, the Granite Stone Glass Air Fryer XL is a strong contender.
Pros: Large 16-quart capacity with expansion ring, three combined heating technologies (halogen, convection, infrared), glass bowl lets you watch food cook, Teflon-free and non-toxic construction, dishwasher-safe parts, self-clean mode, includes two racks plus recipe book, currently discounted with free shipping.
Cons: Large footprint may not suit small kitchens, glass construction means extra care when handling versus a plastic-bodied unit, and as with any appliance ordered online, it's worth checking current stock and color availability before checkout since availability can shift.
As of this review, the Granite Stone Glass Air Fryer XL was listed as purchasable on the official Granite Stone site with an active "Add to Cart" button across all three colorways. Stock levels on any e-commerce site can change quickly, so we recommend confirming current availability and color options directly on the product page before you buy.
The Granite Stone Glass Air Fryer XL delivers a genuinely different take on air frying by combining three heating methods in a large glass chamber you can actually see into. For the price, the included accessories (two racks, expansion ring, mesh basket, recipe book) add real value, and the self-clean function plus dishwasher-safe parts address one of the biggest complaints people have about air fryers in general. If you have the counter space and cook for a family or regularly host, this is worth serious consideration.
