Compact, well-made, and dependable, the Bosch Series 6 Air Fryer is the perfect choice for small households

The included physical user manual is thorough, making it easy to set up and use this appliance – even if you’re a beginner. A physical food guide is also included, which provides a rough cooking guide and tips for each of the air fryer’s eight programs. We do wish the food guide were slightly more detailed and included more food types, especially when it comes to cooking vegetables.
The food guide does come with a QR code, though, that leads you to a Quick Start Guide that features a handful of excellent recipes for this specific air fryer. We just wish there were more of them.
This air fryer also comes with a metal grill rack accessory and five skewers that fit into the grill rack. These are a welcome addition for grilling, but we found removing the hot grill rack difficult after cooking due to the depth of the basket and its metal design. We also wish the grill rack could be locked into the basket’s plate to avoid it moving around and potentially damaging the plate’s non-stick coating long-term.
While the 7.2L basket is a bit bulky, it’s easy to hand wash with minimal elbow grease – though, inside the window is slightly trickier to reach. Fortunately, the basket and its plate are dishwasher-proof, though we at TechRadar tend to recommend hand washing anything with a non-stick coat.
The main design drawback of this air fryer is its volume. We logged a max 68dB reading when the appliance was running at its maximum temperature, making it loud enough that we couldn’t hear our kitchen TV and could hear it from our living room next door. This is particularly loud for an air fryer (based on those we’ve tested) and several decibels louder than the 63dB Bosch claims.

Bosch Series 6 air fryer: performance
- Quality performance across cooking programs
- Useful Shake alert
- Some foods could be crispier
We found the Bosch Series 6 air fryer performed consistently well across its eight cooking programs: Bread, Fish, French Fries, Keep Warm, Meat, Small Pastries, Poultry, and Vegetables.
We started our testing with 500g of frozen fries , utilizing the air fryer’s French Fries preset, while tweaking the time slightly as recommended by the food guide. After 23 minutes, we had fairly evenly cooked fries (a couple were slightly over for my taste), but overall, the fries were fluffy inside and golden outside.
Following the frozen fries, we tried 700g of handmade fries, soaked and with one tablespoon of oil, on the same setting, using the exact preset time and temperature. Again, the fries were fluffy inside and golden outside but could have been a little crispier. Unlike other air fryers, however, the Bosch Series 6 didn’t leave our fries with overdone ends – a common issue we’ve encountered with testing.
Next, we tested the grill and skewer accessories. We loaded up each of the five skewers with chicken, onion, tomato, and peppers – but may have overloaded them a little as the five skewers struggled to fit beside each other. My advice: make sure your cuts of veggies and meat are smaller to avoid this.
The skewers sit on indents in the grill rack, which is placed in the basket. We’ve mentioned our issues with the grill rack generally, but despite the overcrowding, we found our skewers cooked well on the Poultry preset, though some of the vegetables were becoming overdone and the chicken slightly overdone, so we had to remove them a few minutes early. You likely need to adjust this timing based on what you skewer.
We also tried cooking a couple of chicken breasts on the grill rack (with some seasoning and a tablespoon of oil) on the Poultry preset. They came out slightly dry and with not quite enough crisp on the outside for our taste, but overall very tasty.
We had this same crisping issue with drumsticks prepared using a Bosch recipe and dry-rubbed wings (my go-to Cosori recipe), both cooked well and were juicy inside, but the skin didn’t crisp up quite enough. The pre-baked petit pains we cooked on the Bread preset, too were soft inside, but not quite crunchy enough outside.
The Bosch recipes are a great starting point for this air fryer, and we particularly enjoyed its roasted cauliflower and egg omelette muffin recipes (both turned out perfect). The apple turnover recipe, while very tasty, resulted in turnovers with overly soggy bottoms – though that’s likely down to chef error on my part.
Other presets may require some tweaking of the timings. Sausages on the Beef preset were slightly underdone after seven minutes, which may be down to the fact that they were chunky Cumberlands.
Vegetables, too, like most air fryers, require some experimentation. The food guide isn’t very detailed on how long to cook certain vegetables and just covers “Grilled Vegetables.” While this was the perfect preset for my chantanay carrots, my broccoli, onions and peppers needed to be removed early to avoid becoming too charred. Again, this is something we’ve encountered with several air fryers.
Now, if you’ve read our air fryer reviews before, you’ll know we love an air fryer that can bake. The Bosch Series 6 can manage that feat for small cakes and muffins, so we used our usual Ninja muffin recipe with the Muffin preset to test its capabilities. It was perhaps the best result I’ve had for this test, with the muffins perfectly golden on top, not too dry inside, and little to no overspill.
Overall, the Bosch Series 6 performs brilliantly; however, you may need to experiment a bit to get the right balance of crispness and doneness for certain foods.

Value |
This air fryer is excellent value for its price tag, and thanks to regular sales, you can pick it up for closer to £100. |
5/5 |
Design |
The design is pretty compact for its 7.2L capacity, plus it’s easy to use and clean. While the accompanying grill rack and skewers are welcome accessories, we wish they could lock into the basket plate and were easier to remove after cooking. This is also one of the louder air fryers we’ve reviewed. |

Performance |
Performance across all eight cooking programs is solid, though some foods could be slightly crispier on the outside. You may need to experiment a bit for optimal results on certain presets. |

Buy it if
You want a decent capacity air fryer, but haven’t space for a dual-basket
The Bosch Series 6’s 7.2L capacity is pretty sizeable, and while it’s not compact enough to be counted as a small air fryer, it’s nowhere near as big as some competitors. Plus, the handles are detachable, making it slightly easier to store.
You’re looking for a solid, budget air fryer
With its £159.99 price tag, the Bosch Series 6 is already great value for money, but regular discounts see that price knocked down to roughly £100, making it an ideal choice for those on a £100 budget.
You want a streamlined air frying experience
The Bosch Series 6 is a great entry-level air fryer for those who want a straightforward, streamlined experience. It comes with enough features to make it pleasant to use without overwhelming you with extras.
Don’t buy it if
You want to cook more than one food at once
The Bosch Series 6’s capacity means you can fit a decent amount of food in, but if you’ve got a larger household that plans to make larger quantities or food or you want to cook more than one type of food at once, you may struggle with this.
You want a bunch of extras
This is down to personal preference. While this air fryer comes with a grill rack, it only air fries, and the cooking programs cover the basics. If you want features like smart control, synced cooking, or different cooking modes (like grilling and steaming), then this may not be the best choice for you.
How I tested the Bosch Series 6 air fryer
I used the Bosch Series 6 air fryer for a week, cooking a wide variety of foods including fries, sausages, fresh vegetables, and pastries. I tested all the air fryer’s various modes and cleaned the air fryer in line with the instructions provided in the manual. For more details, see
