Crispy Zucchini Chips (Baked or Air Fryer)

These Crispy Zucchini Chips (Baked or Air Fryer) are one of my favorite ways to turn a simple zucchini into a light, crunchy snack. I slice the zucchini extra thin, coat it lightly with olive oil, and season it with salt before baking it slowly until crisp or cooking it quickly in the air fryer. I love serving these chips as a healthier alternative to traditional potato chips, and they also make a simple crunchy side for sandwiches, burgers, and wraps.

Why You’ll Love This Recipe

I love this recipe because it uses just a handful of everyday ingredients while giving me a satisfyingly crisp snack. The zucchini develops a delicate texture and savory flavor without needing breading or deep frying.

I can also choose between two easy cooking methods. When I have extra time, I use the oven for slowly dried, crisp chips. When I want them ready much faster, I use the air fryer. I can change the seasonings easily, making this a versatile recipe whenever I have zucchini to use up.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 large zucchini

1 tablespoon olive oil

1 teaspoon salt

Paprika, optional

I find that a large, firm zucchini works especially well because it is easier to slice into uniform rounds. I use olive oil sparingly since too much oil can make the zucchini softer instead of crisp. Paprika is optional, but I like the extra color and mild savory flavor it adds.

Directions

Oven Method:

I preheat my oven to 200°F.

Using a mandoline, I slice the zucchini into very thin rounds, approximately 1/8 to 1/16 inch thick. I try to keep the slices as uniform as possible so they cook at the same rate.

I place the zucchini slices in a large mixing bowl, drizzle them with olive oil, and gently toss until every slice has a light coating.

I line two baking sheets with parchment paper and arrange the zucchini rounds in a single layer. I make sure the slices do not overlap because this helps them dry and crisp evenly.

I sprinkle the slices evenly with salt and add paprika when I want a little extra flavor.

I bake the zucchini for 2 to 2½ hours, watching toward the end of the cooking time, until the slices are golden, dry, and crisp.

I turn off the oven and allow the chips to cool completely on the baking sheets. I find that they continue to crisp as they cool.

Air Fryer Method:

I preheat my air fryer to 350°F (175°C).

I arrange the thin zucchini slices for seasoning and lightly spritz them with olive oil. Then I season them with salt and paprika, if using.

I place the zucchini slices in a single layer in the air fryer basket. I cook them in batches rather than overcrowding the basket.

I air fry the zucchini for 8–10 minutes, flipping the slices halfway through. Since air fryers can cook differently, I keep a close eye on the thinner pieces toward the end.

Once crisp and golden, I remove the chips and let them cool before serving. Cooling helps the texture become even crispier.

Servings and Timing

This recipe makes approximately 2 servings.

Prep time: 10 minutes

Oven cooking time: approximately 2 to 2½ hours

Air fryer cooking time: approximately 8–10 minutes per batch

Total time for the oven method: approximately 2 hours 10 minutes to 2 hours 40 minutes, plus cooling

Calories: approximately 80 kcal per serving

The exact cooking time can vary depending on how thinly I slice the zucchini and the oven or air fryer I use.

Variations

Garlic and Herb:

I like adding garlic powder along with dried oregano, basil, or Italian seasoning for a more aromatic flavor.

Spicy Zucchini Chips:

When I want some heat, I add cayenne pepper, chili powder, or crushed red pepper along with the salt.

Smoky Paprika:

I replace regular paprika with smoked paprika when I want the chips to have a deeper, slightly smoky flavor.

Parmesan Zucchini Chips:

I can add a light sprinkle of finely grated Parmesan for a richer, savory variation. I use only a small amount so the zucchini can still crisp properly.

Salt and Pepper:

For the simplest version, I skip the paprika and season the zucchini with salt and freshly ground black pepper.

Storage/Reheating

I get the best texture when I eat these zucchini chips shortly after they have cooled. If I have leftovers, I make sure they are completely cool before placing them in an airtight container. Trapped warmth can create condensation and quickly make the chips soft.

I store the chips at room temperature for about 1–2 days. If they lose some of their crunch, I spread them in a single layer and warm them briefly in the oven or air fryer until crisp again. I let them cool for a few minutes before eating because they usually become crispier as they cool.

I avoid microwaving zucchini chips because I find that the microwave tends to make them soft rather than crunchy.

FAQs

Why are my zucchini chips not crispy?

I usually find that thick slices, overlapping pieces, or too much olive oil are the main reasons zucchini chips stay soft. Zucchini naturally contains a lot of water, so I slice it very thin and arrange every piece in a single layer. I also allow the chips to cool completely before deciding whether they need additional cooking.

Do I need to peel the zucchini first?

No. I leave the skin on because it is tender and helps the rounds maintain their shape. I simply wash and dry the zucchini thoroughly before slicing it.

Can I make zucchini chips without a mandoline?

Yes. I can use a very sharp knife, but I take extra care to make the slices as thin and uniform as possible. A mandoline makes this easier because consistent thickness helps all the chips finish cooking around the same time.

Which method makes zucchini chips crispier: the oven or air fryer?

I can get crispy results with either method. I like the oven when I want to slowly remove moisture from a larger quantity of zucchini, while I prefer the air fryer when I want a faster snack with a crisp, golden finish. With either method, thin and evenly sized slices make the biggest difference.

How do I keep homemade zucchini chips crispy?

I let the chips cool completely before storing them, and I never seal warm chips inside a container. If they soften later, I put them back in the oven or air fryer briefly to remove some of the absorbed moisture and restore their crunch.

Conclusion

Crispy Zucchini Chips are a simple way for me to transform fresh zucchini into a savory snack with plenty of crunch. With only zucchini, olive oil, salt, and an optional sprinkle of paprika, I can make a light alternative to traditional chips without deep frying.

I especially like having both cooking options available. I use the oven when I want a slow-baked batch and the air fryer when I need something much quicker. Either way, thin slices, a light coating of oil, and enough space between each piece help me get deliciously golden, crispy zucchini chips.
