Potatoes Au Gratin | Air Fryer Side Dish
If you haven’t gotten an Air Fryer yet, you’re missing out. Not only do they make dishes like these Potatoes Au Gratin so much easier to prepare, but they also make them a little healthier. An Air Fryer needs hardly any oil to function. This means your usual dishes that are bogged down with oil, won’t be!
It’s a lot easier to slice the potatoes for this dish by using a mandolin slicer. Be careful though, don’t go for a cheaper mandolin slicer as it’s easy to cut yourself on those. Be sure you get one with a guard so your fingers will stay intact. it’s well worth it though and you can use it for many more of my recipes outside of these Potatoes Au Gratin.
What Does Au Gratin Mean?
Typically this refers to a casserole where you’ve created a browned crust on top of a dish. Sometimes this is done ith breadcrumbs, sometimes cheese–or if you’re craving some good old fashioned American topping, I’ve seen this done with crushed, buttered corn flakes.
I will not judge, because by golly that cornflakes topping is delicious!
I debated whether these were au gratin or not, since I don’t use a topping for them. But the simplest way to get a browned crust on these–and also a delicious way to do that–is to top with grated cheese for the final 2-3 minutes of cooking.
