Air Fryer Sweet Potato Dog Treats: All the Crunch, None of the Wait

If you've made our Sweet Potato Dog Chews, you know they're worth the wait — but "worth the wait" and "a dog is currently staring at you" don't always line up. This version trades the low-and-slow oven method for an air fryer and a much shorter attention span.

Why Air Fryer Treats Beat the Alternatives

Thin sweet potato slices go from perfectly golden to burnt fast, which is exactly where an air fryer earns its keep over a stovetop or a hot oven. Circulating air cooks every slice at the same rate, so you're not fishing out the pieces near the oven's hot spot while the rest are still soft. No oil is required either — sweet potato crisps up fine on its own, which means fewer added fats for a dog's stomach to deal with and a cleaner-label treat than most of what's on a store shelf.

It's a win for the person making them too: same appliance you already use for dinner, a fraction of the preheat time of a full oven, and containers that rinse clean instead of a baking sheet that needs scrubbing.

I've had the Ninja Crispi Glass Air Fryer for over a year and it's the appliance that gets used most in this kitchen. It uses glass containers rather than a coated basket — PFAS-free, and transparent, so with something as quick to scorch as thin sweet potato slices, you can watch the edges go from pale to golden without pulling the container out every couple of minutes to check. Nothing sticks, both containers are dishwasher-safe, and it browns evenly enough that you're not sorting through a batch for the pieces that survived. The 6-cup container is the right size for a single batch of these — save the 4-quart for dinner. This is the one we use (Amazon) — the Ninja Crispi Glass Air Fryer — for treats and everything else.

What You Need

• 1 large sweet potato, washed and sliced into 1/8-inch rounds — a simple mandoline slicer (Amazon) keeps every round the same thickness, which matters more than you'd think for even crisping
• 1 tsp melted coconut oil, optional — skip it entirely for a true one-ingredient treat
• A glass-container air fryer like the Ninja Crispi makes it easy to catch these right at golden — the 6-cup container is the right size for one batch

How to Make Air Fryer Sweet Potato Dog Treats

1. Preheat your air fryer to 350°F (bake program) for 3 minutes..
2. Slice the sweet potato into thin, even rounds — the thinner and more even, the crispier they'll turn out.
3. Toss lightly with coconut oil if using.
4. Arrange in a single layer in the container, working in batches so pieces don't overlap.
5. Air fry 10–12 minutes, flipping halfway, until the edges are golden and crisp.
6. Cool completely — they'll keep crisping as they cool.

Chewy or Crispy?

This recipe makes a crisp, chip-like treat in under 25 minutes. If your dog is more of a slow-chew type, the original oven-dehydrated Sweet Potato Dog Chews bake low and slow into a softer, longer-lasting chew — same ingredient, different personality.

Storing Them

Store in an airtight container at room temperature for up to a week.
