If you’re following keto, this list of keto-approved cheeses is one you should check out.

If you’re not worried about keto, just worried about this recipe working out, then any sliced cheese will do. Cheddar, provolone, Munster, Colby Jack … any of them will work.

The thinner the cheese, the less it will spread as it bakes. So if you’re getting cheese sliced at a deli counter, ask for it to be cut as thin as possible.

But, packaged cheese is just fine too. The ones that come as a block separated by tiny parchment paper sheets is better than individually wrapped slices, mostly because the former tends to have less preservatives and will bake better because of that.

You can slice your own cheese, if you want, but make sure to slice thin, uniformed pieces if you do so that the cheese will bake evenly.

And, if you want, you can use dollops of Parmesan cheese to make these too. The very finely grated, basically powdered form, of Parmesan cheese won’t work, though. You need a thick grated Parmesan cheese to make a homemade Parmesan crisp.

We don’t suggest using shredded cheese, since the preservatives in shredded cheese don’t allow it to melt as well. But if you don’t have sliced cheese, shredding a block of cheese will work in a pinch.

A lot of homemade cheese cracker recipes call for sea salt to be sprinkled on top of the cheese. Personally, we found that version to be really salty.

Instead, we use regular table salt for a better taste.

If you’ve a homemade Cheez It crackers TikTok recipe, then come to this post, you know the TikTok version says to use a straw to poke a hole in the center of the cheese pieces. That’s because Cheez It crackers have a hole in the center.

But, when you bake slices of cheese, air pockets form and pop and create holes all throughout the cheese. So even if you go through the trouble of putting a hole in the center of each piece of cheese, you’ll lose it at the end because so many other holes will have formed around it, plus melted cheese will have filled that hole. So save yourself the time and don’t poke the hole (we tried it).

We have a basket-type air fryer and tried this recipe in there … and failed.

You definitely have to line the air fryer basket so the cheese doesn’t automatically melt through the holes in the basket. But, the weight of the cheese is not enough to weigh down the air fryer liner. So, that ends up flying up into the coils, burning, and your cheese melts through the holes.

No good.

If you have a convection oven-style air fryer, you might have better luck. But we don’t have one, so we weren’t able to try it.

If you have any leftover homemade cheese crisps, store them in an airtight container in the fridge.

Try to use them as soon as possible, though, because they won’t be as crispy and fresh after they’ve sat in the refrigerator.

If you’re making Parmesan crisps, as detailed above, or using sliced cheese to make these keto cheese crackers, they can be frozen in a freezer-safe container.

But, when you defrost them, they won’t be as fresh or crisp as when you first make them.

So yes, homemade cheese crisps can be frozen, but we don’t recommend it.
