How to Make This Crispy Baked Zucchini Chips
Step 1: Slice with Precision
Wash 2 medium zucchinis and trim off the stem ends. Use a mandoline slicer set to 1/8-inch (3mm) thickness to slice the zucchini into perfectly uniform rounds. The Pro Secret: Uniform thickness is non-negotiable. If some slices are thick and others are paper-thin, the thin ones will burn to ash long before the thick ones ever turn crisp.
Step 2: The Moisture-Extraction Sweat
Line a large cutting board or baking sheet with a double layer of paper towels. Lay the zucchini slices out in a single layer, making sure none of them overlap. Lightly sprinkle fine sea salt over the tops of all the slices. Let them sit undisturbed at room temperature for 15 to 20 minutes. You will see large beads of water sweat out onto the surface of the squash.
Step 3: Press and Dry
Lay another double layer of paper towels over the sweated zucchini slices. Press down firmly across the top with your hands to blot away all the extracted water. Flip the slices over and pat the undersides dry as well. Removing this surface liquid cuts your oven drying time in half and guarantees a crunchier chip.
Step 4: Season the Chips
Preheat your oven to 225°F (107°C). Line two large, rimmed baking sheets with sheets of unbleached parchment paper. In a small bowl, combine 3 tablespoons of finely grated Parmesan cheese, 1/2 teaspoon of garlic powder, 1/4 teaspoon of smoked paprika, and 1/4 teaspoon of freshly cracked black pepper. Brush both sides of each zucchini slice lightly with olive oil, then sprinkle the Parmesan spice mix evenly over the tops.
Step 5: Arrange in a Single Layer
Place the seasoned zucchini slices onto your parchment-lined baking sheets in a single layer. Make sure the edges are close together but not overlapping or touching. As the water evaporates during baking, the slices will shrink in size by about 40%.
Step 6: Bake Low and Slow
Bake at 225°F for 1.5 to 2 hours. Around the 75-minute mark, check on the progress. Swap the positions of the two baking sheets (top rack to bottom rack) to promote even heat circulation. The chips are finished when they turn a light golden brown, look visibly dry, and feel firm to the touch when tapped with a finger.
Step 7: Cool to Lock in the Crunch
Remove the pans from the oven and let the chips sit on the warm parchment paper for 10 minutes. As they cool down to room temperature, the remaining natural starches and melted cheese firm up, giving the chips their final, shatteringly crisp texture.
Pro Tips for Best Recipe
Always Use a Mandoline: Trying to cut 1/8-inch slices with a chef’s knife leads to uneven slices that cook at different rates. A basic mandoline slicer guarantees every chip dehydrates at the exact same speed.
Use Finely Grated Parmesan: Use powdery, finely grated Parmesan (like the texture of sand) rather than shredded cheese. Powdered cheese adheres to the oily zucchini surface far better and bakes into a uniform, crispy shell.
Never Skip the Parchment Paper: Zucchini slices will stick aggressively to bare aluminum pans or tin foil as their natural sugars caramelize. Parchment paper or a silicone baking mat lets you lift the finished chips right off without tearing.
Watch the Oven Color Closely: Because of the natural sugars in zucchini and cheese, the transition from golden brown to burnt happens fast during the last 15 minutes. Check the oven frequently towards the end.
Storage
- To Store: Zucchini chips absorb ambient humidity very quickly. Once they have cooled completely to room temperature, place them in an airtight glass container lined with a dry paper towel. Store at room temperature in a cool, dark pantry for up to 3 days. Do not refrigerate, as cold humidity will make them soggy.
- To Re-Crisp: If your stored chips absorb moisture and soften up, lay them back on a parchment-lined baking sheet and warm them in a 250°F (120°C) oven or air fryer for 3 to 5 minutes. They will instantly crisp right back up as they cool!
Frequently Asked Questions
Why did my zucchini chips turn out soggy?
Soggy chips are caused by three main mistakes: slicing the squash too thick, rushing the moisture-sweating step, or baking at too high a temperature. Baking above 250°F steams the inside of the vegetable before the water has a chance to evaporate.
Can I make these in an air fryer?
Yes! Set your air fryer to 200°F (93°C). Place the seasoned slices in a single layer in the air fryer basket (you will need to work in batches). Air fry for 25 to 30 minutes, gently shaking the basket halfway through until the chips are golden and dry.
Do I need to peel the zucchini first?
No, leaving the green skin on is recommended! The skin provides structural integrity that holds the delicate chips together as they shrink, while adding beneficial fiber and a pop of green color.
What are the best low-carb dipping sauces for these chips?
Because these chips have a savory Parmesan-garlic coating, they pair wonderfully with warm marinara sauce, homemade garlic aioli, spicy sriracha mayonnaise, or cool ranch dressing.

Ultra Crispy Baked Zucchini Chips
Ingredients
- The Veggie Base
2 medium fresh zucchinis (unpeeled, trimmed)
½ tsp fine sea salt (for sweating moisture)
- The Crispy Parmesan Seasoning
1 tbsp extra virgin olive oil
3 tbsp finely grated Parmesan cheese (powdered texture)
½ tsp garlic powder
¼ tsp smoked paprika
¼ tsp freshly cracked black pepper
Instructions
Using a mandoline slicer, slice 2 medium zucchinis into uniform 1/8-inch thick rounds.
Lay the slices in a single layer across a paper-towel-lined board. Sprinkle lightly with fine sea salt. Let sit for 15 to 20 minutes until water droplets form.
Press additional paper towels over the tops of the slices to absorb all extracted liquid.
Preheat your oven to 225°F (107°C) and line two baking sheets with parchment paper. Brush the zucchini slices lightly with olive oil. Sprinkle the Parmesan cheese, garlic powder, smoked paprika, and pepper evenly over the tops.
Place the seasoned slices onto the parchment paper in a single layer without touching. Bake at 225°F for 1.5 to 2 hours until golden and dry, swapping pan positions halfway through.
Remove from the oven and let cool on the pans for 10 minutes to reach maximum crispiness before serving.
Notes
Keep Slices Uniform: A mandoline is essential for making sure every slice dries out at the same rate. Don’t Rush the Sweat: Letting salt extract the internal water prevents steam from making the chips soggy. Use Powdered Cheese: Fine, sandy Parmesan sticks better to the oiled slices than shredded cheese. Parchment is Mandatory: Never bake directly on aluminum foil or bare pans, or the chips will tear. Store Room Temp: Store leftovers in an airtight jar with a dry paper towel—never in the fridge!
