The bread is uniformly crisp and golden. In a skillet, I have never achieved the same golden color edge-to-edge as I have in the air fryer. And the crispness? I’m talking audibly crisp. In fact, my son found it too crisp for his taste (sigh), but the air fryer makes it easy to experiment with time and temperature to achieve your ideal texture. Keep in mind that air fryers vary in strength, so you may need to tweak my instructions for your particular model.
You’ll never have unmelted cheese. One challenge of making grilled cheese in a skillet is that the exterior can get to the color you want — or even burn — before the cheese is melted. There are ways around this, including first griddling the interior sides of the bread or covering the pan with a lid. Still, you cannot beat the intense heat of the air fryer for ultimate melt. In fact, it can help to wait a minute or two to slice an air fryer grilled cheese to let it briefly set and cool. The appliance also handles sliced cheese with ease.
If you prefer to use vegan cheese, I got incredible results in the air fryer, to the point that it was indistinguishable from dairy. When I tried a vegan grilled cheese using the same product in the skillet, the shreds did not come close to melting the same way, even with a precook of the bread.
You can use less fat. As I’ve written before, it’s best to think of the air fryer as a less-fat, not no-fat, strategy for cooking. You still need something for color and flavor, as well as preventing the food from scorching. All it takes is a minimal coating of fat on the outside of the bread. My top pick is mayo, though you can use oil or softened/melted butter (salted or unsalted!) instead. Compared to how much you might typically need to coat a skillet, especially if you add more after you flip the sandwich, it’s considerably less fat in the air fryer.
It’s easier to make multiple sandwiches. Making two sandwiches in one skillet is often not feasible, especially if you toast the bread first. Even a 12-inch skillet may struggle to hold more than one sandwich. The air fryers I tested this recipe in — an Instant Vortex Plus 6-quart and Cosori 5.8-quart — had plenty of room for two sandwiches. I probably could have squeezed in a third with slightly differently shaped slices of bread.
The heat is even and hands-off. I appreciate the more hands-off nature of air fryer grilled cheese. In a skillet, I frequently have to tweak the heat. Not so in the air fryer. The heat is incredibly steady, so set it at one temperature and you’re good to go. While it’s a good idea to stay near the kitchen in general when you’re cooking, there’s considerably less babysitting for an air fryer than a skillet. (Now, if you’re just familiarizing yourself with your appliance and trying to figure out the ideal temperature, you might need to experiment your first time or two, but as with a regular oven, once you’ve figured out how it runs — hotter or cooler than expected or spot on — the guesswork is over.) And when you can fully assemble the sandwich from the get-go, just put it in the basket, flip once and you’re done.
