Begin by washing and slicing your zucchinis into thin rounds, approximately 1/8 inch thick. The uniform thickness is key to achieving perfectly crispy chips.

To prevent your zucchini chips from becoming soggy during the cooking process, it's essential to remove excess moisture. Place the zucchini slices between two layers of paper towels and set a heavy baking sheet or cast-iron skillet on top. Let them sit for about 15 minutes; this will help draw out the excess water.

After the zucchini slices have been adequately drained, place them in a bowl and drizzle them with the avocado oil. Sprinkle the garlic powder and salt evenly over the slices. Gently toss to ensure that each chip is coated with the delicious seasonings.

Preheat your air fryer to 325°F (160°C). Preheating is crucial to achieving that perfect crunch.

Once your air fryer is ready, arrange the seasoned zucchini slices in a single layer in the air fryer basket, making sure they don't overlap. Depending on the size of your air fryer, you may need to work in batches.

Cook the zucchini chips at 325°F (160°C) for 8 minutes. After the initial 8 minutes, flip the chips using tongs or a spatula to ensure even cooking. Then, continue to air fry for an additional 4-6 minutes, or until the chips are golden brown and crispy. Keep a close eye on them during this time to avoid overcooking.
