Baked Zucchini Chips: Crispy, Healthy & Irresistibly Crunchy

Pro Tips for the Best Baked Zucchini Chips

• Aim for thin, even slices: Slices around ⅛ inch (3 mm) thick are ideal. A mandoline slicer makes this easy, but a sharp knife and a steady hand work well too. Thicker slices will take longer to bake and result in a chewier texture rather than a crisp chip.
• Salt and drain thoroughly: Zucchini has a high water content. Salting the slices and letting them sit for 15–20 minutes draws out excess moisture, which is the single most important step for achieving crispy chips. Pat them dry thoroughly before proceeding.
• Use a light coating of oil: A generous drizzle or spray of olive oil ensures even browning and crisping during baking. Too little oil will leave them dry; too much will make them greasy.
• Arrange in a single layer: Overcrowding the baking sheet traps steam and prevents crisping. Give each slice enough space for air to circulate freely.
• Flip halfway through: Gently turning the slices halfway through baking promotes even browning and ensures both sides become crisp.
• Watch closely at the end: Keep an eye on your chips towards the end of baking. Once they turn golden brown and feel crisp to the touch, they are done. Avoid over-baking, which can cause them to burn.
• Cool completely before storing: Letting the chips cool on the baking sheet allows any residual moisture to evaporate, helping them stay crisp for longer.
• Extra flavour boost: For a cheesy, savoury twist, toss the dried zucchini slices with a tablespoon of grated Parmesan cheese along with the seasonings before baking.

Frequently Asked Questions

• Can I use something other than a mandoline to slice the zucchini? Absolutely. While a mandoline creates perfectly even slices, a sharp knife works well too—just be sure to slice as thinly and evenly as possible.
• Do I need to rinse the salt off the zucchini before baking? No. Rinsing would wash away the seasoning and all the flavour. Simply pat the slices dry with kitchen paper after salting and draining.
• My zucchini chips are soggy—what went wrong? There are a few possible reasons: the slices may have been too thick; you may not have removed enough moisture (ensure proper salting and drying); or the slices may have been overcrowded on the baking sheet, leading to steaming instead of crisping.
• Can I add anything else to the zucchini chips besides seasonings? Yes. Grated Parmesan cheese adds a delightful salty, savoury note. Chopped fresh herbs like rosemary or thyme, or a pinch of garlic powder, also work wonderfully.
• Are zucchini chips keto-friendly? Yes. They are low in carbohydrates and calories and are a good source of fibre, making them a great keto-friendly snack option.
• Can I fry zucchini chips instead of baking them? While frying is an option, baking is a healthier approach. It allows you to control the amount of oil used and avoids the formation of unhealthy trans fats associated with deep frying.

Storage Instructions

Store leftover zucchini chips in an airtight container at room temperature for up to 3 days. They may lose some crispness over time, but they will still be enjoyable. For the best texture, consume them within the first day or two. Avoid refrigerating, as this can introduce moisture and make them soft.
