If you want to add real grill and air-fry capability to a compatible Bosch oven without buying a second countertop appliance, choose BOSCH HEZ629070; if you need a standalone 12.68 Qt air fryer that also works as a smokeless indoor grill for a family of four to six, choose LIAUHO Air Fryer.
• BOSCH HEZ629070 — biggest strength: it's a genuine two-in-one tray that brings air-fry and barbecue-style grilling into your existing Bosch oven, so the cooking space you already have does double duty.
• BOSCH HEZ629070 — biggest trade-off: it is not an appliance. It's a 17.91" x 17.91" x 1.34" anthracite tray weighing 1.1 kg, so it only makes sense if you own a compatible Bosch oven and are willing to preheat that oven for every batch.
• LIAUHO Air Fryer — biggest strength: a self-contained 1700W, 12.68 Qt countertop unit with 360° hot air circulation, 176–410°F control, a viewing window and six presets — large-batch air frying and indoor grilling with zero oven involved.
• LIAUHO Air Fryer — biggest trade-off: it's a countertop commitment — roughly 15.75" W x 11.02" D x 11.81" H, about 11 lb, plus cable and plug space, and some assembly is required before first use.
• Who each pick is for: the Bosch tray is for existing Bosch oven owners who want grill marks and crisped food from the oven they already have; the LIAUHO is for anyone who wants one plug-in machine to fry and grill big family portions.
The HEZ629070 is best understood as an accessory, not a device. It's a rectangular tray built from stainless steel, cast iron and aluminium in an anthracite finish, measuring 17.91" L x 17.91" W with a 1.34" thickness and weighing 1.1 kg. That combination of materials is the interesting part: cast iron and aluminium are the metals you want under food when you're chasing browning and grill-style sear marks, while the stainless content helps the tray shrug off the heat cycles of an oven. Bosch sells it as an air fry and barbecue tray, which tells you the intent — it's meant to sit inside a compatible Bosch oven and let that oven behave more like an air fryer or an indoor grill.
In practical terms, this is for the person who already owns a Bosch oven and resents the idea of buying a second appliance that eats counter space. Slide the tray in, run the oven's air-fry or grill setting, and you get crisped edges on vegetables, roasted chicken pieces with caramelised surfaces, or food with the kind of contact browning a basket-style air fryer struggles to produce. Because it's a flat tray rather than a basket, you can spread items out in a single layer — which is exactly what you want when browning matters more than tossing.
Who should skip it? Anyone without a compatible Bosch oven, first of all — this tray has no heating element, no fan and no cord of its own, so it does nothing on its own. Also skip it if you want speed without preheating, or if you want to cook a big batch of wings in one enclosed chamber. A tray in an oven heats the whole oven cavity; a countertop air fryer heats a small box. If convenience and quick weeknight turnaround are your priority, this isn't the tool. And if you're not sure the tray fits your specific model, check that before anything else.
The LIAUHO is the opposite philosophy: one self-contained machine that does the whole job. It's a 1700W tabletop unit with a 12.68 Qt (12 L) chamber, powered by 110V and built from PP, galvanised iron and glass with a stick-prevention coating. The headline number is that capacity — 12.68 quarts is explicitly sized for four to six people, which means a full batch of chicken wings, a big bowl of fries or a tray of mixed vegetables in a single run instead of three rounds. For a family dinner or a weekend gathering, that's the difference between everyone eating hot food together and someone eating the last batch alone.
The heating story is straightforward and well specified: 1700W with 360° hot air circulation, temperature adjustable from 176–410°F and a timer running 5–65 minutes. That range covers the full arc from low-temperature thawing (frozen steak) up to high-heat crisping (onion rings). Six preset modes on the LED panel mean a beginner can start cooking without learning settings first, while anyone who wants control still has it — the two aren't mutually exclusive here. The listed uses are broad: cakes, chicken wings, fish, meat, shrimp and vegetables.
The details that matter day to day are the viewing window and the safety design. The clear glass lid lets you watch food without lifting it, which avoids dumping heat every time you're curious — a small thing that genuinely changes results when you're browning. Open the lid and the unit cuts power automatically, which is a sensible guard against burns, and the long ergonomic handle keeps your hand away from hot surfaces. Cleanup is a wipe of the non-stick tray, even for sticky things like cheese sticks. Non-slip feet keep it planted on the counter and protect the surface underneath, and it ships with a 5-year manufacturer warranty.
Who should skip it? Anyone with a genuinely tiny kitchen. This is a roughly 15.75" x 11.02" x 11.81" box that lives on your counter permanently. It also requires some assembly, and it's corded electric at 110V, so you need an outlet where you plan to use it. If you already have a Bosch oven and just want to unlock its air-fry potential, buying a whole second appliance may be redundant.
• Best for using the oven you already own → BOSCH HEZ629070. It's an add-on tray for a compatible Bosch oven, nothing more and nothing less.
• Best for true standalone cooking → LIAUHO Air Fryer. It plugs in, heats itself and needs no other appliance.
• Best for feeding 4–6 people at once → LIAUHO Air Fryer. The 12.68 Qt chamber is sized for exactly that.
• Best for grill-style browning and sear marks → BOSCH HEZ629070. Cast iron and aluminium construction plus direct oven heat are built for contact browning.
• Best for small households and light portions → BOSCH HEZ629070. A flat tray on a single layer suits one or two people better than a 12.68 Qt chamber.
• Best for precise temperature control → LIAUHO Air Fryer. 176–410°F plus a 5–65 minute timer and six presets give you a repeatable dial-in.
• Best for watching food as it cooks → LIAUHO Air Fryer. The clear glass window means no heat loss from lifting a lid.
• Best for easy cleanup → LIAUHO Air Fryer. The non-stick tray wipes down with a damp towel.
• Best for counter space and simplicity → BOSCH HEZ629070. It stores in the oven; there's no footprint to give up.
In my opinion, the LIAUHO Air Fryer is the better buy for most people, because it's a complete appliance rather than a piece of one. It does the frying and the indoor grilling itself, in large enough batches for a family of four to six, with a viewing window, presets, auto shut-off on opening and a 5-year manufacturer warranty. The Bosch HEZ629070 is genuinely clever — cast iron, aluminium and stainless steel in a tray that turns a Bosch oven into an air fryer and grill — but it's only clever if that oven is already in your kitchen. If it is, and you're happy to preheat it, the tray is the smarter, lower-clutter answer. If it isn't, the LIAUHO is the one I'd buy.

FAQ
how to air fryer grilled cheese
how to air fryer grilled cheese sandwich
Build the sandwich, press it lightly so it holds together, and cook it flat rather than stacked — a single layer is what gives you even browning. The LIAUHO's 176–410°F range lets you pick a moderate setting for melting the cheese before the bread darkens. Both options work, but the enclosed chamber of the LIAUHO keeps the bread from drying out as quickly.
how to air fryer grilled chicken
Pat the chicken dry, season it, and keep pieces in one layer so the 360° hot air can circulate around each one. Use the LIAUHO's 176–410°F control and its 5–65 minute timer to cook through, checking colour through the glass window rather than opening the lid. On the Bosch tray, spread pieces flat for better contact browning and turn them partway.
how to air fry grilled cheese
The principle is the same as above, but keep the heat moderate and the time short — cheese melts fast and bread browns faster. On the LIAUHO, a preset mode gets a beginner close on the first try, then adjust from there. On the Bosch tray, use the oven's grill setting and watch closely, since direct oven heat browns the surface quickly.
