The Gourmia GAF798 is a large-capacity, 7-quart air fryer from Gourmia's big lineup of air fryers, which includes many similar models with slightly different presets and features. It has presets for specific foods like 'Fries' and 'Bacon' as well as for various methods like 'Reheat,' 'Bake,' and 'Broil.' Its controls also include a preheat mode and 'Turn Food' reminder, which are somewhat uncommon. Its 7-qt capacity is enough to cook for about four people.
Our Verdict
The Gourmia GAF798 is a good air fryer. It makes good-quality fried food, so things like vegetables, French fries, and chicken wings come out mostly golden brown and well-cooked. However, a small proportion is still undercooked when your food is ready. It cooks food quickly but has a very small fan speed range, which makes it less versatile and less useful for non-air frying methods like dehydrating.

Differences Between Sizes And Variants
The Gourmia GAF798 only comes in 'Black,' and the label for the unit is available. There's also the Gourmia GAF799, which has the same capacity, features, and power but has a window so you can see into the basket during cooking. We expect our results to be valid for that model as well.
If you encounter another variant, let us know in the comments, and we'll update our review.
Popular Air Fryer Comparisons
The Gourmia GAF798 is a mid-range air fryer. It has a good frying performance and includes a preheat mode and 'Turn Reminder' feature, which aren't standard on all air fryers. It has a good amount of cooking surface area in its 7-qt basket, but it's worth noting that some 6-qt fryers have the same amount of surface area, meaning if you want to upgrade your 6-qt fryer for something bigger, you might want an 8-qt model like the Ninja Foodi DZ201. It has modes for different foods and cooking methods, but it's not as versatile as models like the COSORI TurboBlaze, which offers more fan speed options.

Test Results
It has a 7-qt overall capacity, which is enough to cook for about four people. However, its basket's surface area is around the same size as some fryers with a smaller overall capacity, so you have about as much room to arrange your food in a single layer as you do in the 6-qt Dreo ChefMaker.
It's decently versatile. It has a pretty good range of temperatures but doesn't get as hot as some air fryers. Its fan speed also doesn't change much between settings. There's a slightly lower fan speed for the dehydrate mode, but more versatile air fryers use a much lower fan speed for dehydrating.
There are nine different modes for different foods and cooking methods. Most are effectively identical since the only difference is the default cook time, which you can adjust. However, some modes let you select a longer cook time, and when using 'Dehydrate' or 'Keep Warm,' the preheat mode and turn reminder are unavailable.
- Air fry: 170 - 400°F, 1-60 minutes
- Fries: 170 - 400°F, 1 - 60 minutes

- Bacon: 170 - 400°F, 1 - 60 minutes

- Dehydrate: 90-170°F, 30 minutes - 24 hours, lowest fan speed, turn reminder and preheat mode not available
- Keep warm: 150 - 200°F, 1 minute - 8 hours, turn reminder and preheat mode not available
It makes good-quality fried food. By the time your food is ready, most of it is well-cooked, golden brown, and crispy when it is ready. However, some parts are still undercooked.
Unlike most air fryers, it has an optional preheat mode that indicates when it's fully heated.
It has mediocre temperature stability. It recovers its temperature slowly after you add food. During cooking, the temperature is decently stable, but there is some variation, making it difficult to predict when your food will be ready and to cook delicate foods like fish.
