How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to add real air-fryer and grill capability to a Bosch oven you already own, choose BOSCH HEZ629070; if you need a standalone electric grill that air fries, bakes, roasts, broils and dehydrates on its own, choose OLIXIS Grill Outdoor/Indoor. These two products share the word "air fry" and almost nothing else. One is an accessory tray. The other is a complete countertop appliance. Getting that distinction right is the whole decision.
• BOSCH HEZ629070 — biggest strength: a large 17.91" x 17.91" rectangular tray in stainless steel, cast iron and aluminium that slots into a Bosch oven and turns it into an air-fry and grill surface.
• BOSCH HEZ629070 — biggest trade-off: it does nothing on its own. No cord, no heating element, no controls. Without a compatible Bosch oven underneath it, it is just a heavy tray.
• OLIXIS Grill Outdoor/Indoor — biggest strength: a self-contained 1550-watt electric grill with 8 functions, 4 temperature modes, a 140°F to 450°F range and a non-stick plate plus fry basket.
• OLIXIS Grill Outdoor/Indoor — biggest trade-off: it is a 16.5-pound freestanding unit that takes up counter or table space, and it is a different machine than the oven you already cook in.
• Who BOSCH HEZ629070 is for: existing Bosch oven owners who want air-fry and grill results without buying another appliance.
• Who OLIXIS Grill Outdoor/Indoor is for: anyone without a suitable oven, or anyone who wants one portable electric unit for indoor and outdoor cooking.
The BOSCH HEZ629070 is an air fry and grill tray, not an appliance. That framing matters more than any spec on the sheet. It measures 17.91" long by 17.91" wide by 1.34" thick, weighs 1.1 kg, and comes in a single anthracite finish. The material build is stainless steel, cast iron and aluminium, which tells you the design intent: a rigid, heat-tolerant surface that can take high oven temperatures and hold food without warping. The rectangular shape is deliberate too — it is made to sit on an oven rack and cover useful cooking area, not to perch on a countertop.
What it does best is extend hardware you already own. If there is a compatible Bosch oven in your kitchen, this tray is the cheapest way to add air-fry and grill style cooking without another box on the counter. You keep one cooking appliance, one cleanup zone, and one place where food gets hot. For someone with limited counter space, that is a genuinely strong argument. The cast iron and aluminium in the stack also suggest good heat spread, which is what you want when the goal is even browning rather than hot spots.
OLIXIS Grill Outdoor/Indoor: Who It's For
The OLIXIS Grill Outdoor/Indoor is the opposite philosophy. It is a freestanding electric grill, 17.72" deep by 16" wide by 10.43" high, weighing 16.5 pounds, running on 120 volts and 1550 watts. It is described as an 8-in-1 multifunctional unit, and the function list is specific: air fry, bake, roast, vegetable, steak, reheat, broil and dehydrate. Those are driven by four temperature settings — Low, Med, High and Max — across a working range of 140°F to 450°F. That spread covers both ends of real cooking: low enough to dehydrate herbs and jerky-style snacks, hot enough to sear a steak.
The accessories list is what separates it from a plain grill. You get a non-stick grill plate and a fry basket, plus a grill cover and user manual. The non-stick coating is there for easy release and less oil, and the removable plate is a real convenience when it is time to clean. The fry basket is the piece that makes the "air fryer vs grill" question interesting here, because this unit does both jobs in one housing. It replaces a countertop air fryer, a small oven and a grill with a single machine — which is exactly the trade a lot of small kitchens and balconies need.
Side-by-Side: Which Should You Choose?
• Best for existing Bosch oven owners → BOSCH HEZ629070. It is built to drop into an oven and add a large grill and air-fry surface with zero extra footprint.
• Best for a complete standalone appliance → OLIXIS Grill Outdoor/Indoor. It has its own 1550-watt element, controls and 8 functions, so it needs nothing else.
• Best for cooking surface size in one flat piece → BOSCH HEZ629070. A 17.91" x 17.91" rectangular tray gives you a wide, even area on an oven rack.
• Best for temperature control → OLIXIS Grill Outdoor/Indoor. Four modes and a 140°F to 450°F range give you dialed-in control the tray simply cannot offer.
• Best for dehydrating and low-and-slow work → OLIXIS Grill Outdoor/Indoor. Dehydrate is one of its listed functions; the Bosch tray has no independent heat source at all.
• Best for easy cleanup → OLIXIS Grill Outdoor/Indoor. Non-stick coating and a removable plate are named features; the Bosch tray is a bare metal surface.
• Best for portability and outdoor use → OLIXIS Grill Outdoor/Indoor. It is free-standing, electric and light enough at 16.5 pounds to move between balcony, yard and campsite.
• Best for minimal kitchen clutter → BOSCH HEZ629070. It stores flat at 1.34" thick and adds no second appliance to your counter.
In my opinion, most people searching this comparison should buy the OLIXIS Grill Outdoor/Indoor. It is a complete, self-sufficient appliance with a real temperature range, real functions and the non-stick plate and fry basket you need on day one — no dependency on which oven you happen to own. I would only steer you to the BOSCH HEZ629070 if you already own a compatible Bosch oven and want to expand it rather than replace it. That is a genuinely smart, low-footprint move for the right kitchen. But it is a conditional buy, and the OLIXIS is not.
how to air fryer grilled cheese
Build the sandwich, butter the outside, and place it on the non-stick grill plate or in the fry basket of the OLIXIS unit. Use a medium setting so the bread toasts before the cheese over-melts, and flip halfway. With the BOSCH tray, do the same on the tray inside a compatible oven and turn once.
how to air fryer grilled cheese sandwich
A grilled cheese sandwich air fries best when it is not overloaded — one layer of cheese, bread pressed flat. On the OLIXIS, the non-stick coating means you need very little butter or oil. On the Bosch tray, use the oven's own heat and check at the halfway point.
how to air fryer grilled chicken
Pat the chicken dry, season it, and cook on a high setting for searing and browning. The OLIXIS reaches 450°F at its Max setting, which is where you get color on the outside. On the Bosch tray, the oven supplies the heat and the cast iron and aluminium build helps spread it evenly.
how to air fry grilled cheese
Same principle as above: moderate heat, a little fat, and a flip. The OLIXIS fry basket and non-stick plate both work here and clean up easily because the plate is removable. The BOSCH HEZ629070 works too, but only when it is sitting inside a compatible Bosch oven.
