• 1 teaspoon oregano
• Kosher salt, to taste
• black pepper, to taste

Ingredient Notes

• Zucchini: The base of the recipe. Medium zucchini provide the ideal moisture level and structure for crisp baking.

• Oregano: Brings a subtle herbal note that complements the parmesan beautifully.
• Grated parmesan cheese: Creates the crispy, golden crust and rich umami flavor.

Tools & Equipment Needed

• Parchment paper (optional alternative to spraying pans)
• Sharp knife or mandoline slicer
• Cutting board
• Measuring spoons
• Measuring cup
• Tongs or clean hands for tossing

Optional but helpful:

Step-by-Step Instructions

1. Preheat the oven to 375°F. Lightly spray two large non-stick sheet pans with avocado oil spray. Alternatively, line them with parchment paper.
2. Slice the zucchini into ¼-inch slices using a sharp knife or mandoline slicer. Aim for even thickness so the chips cook uniformly.
3. Divide the slices from the 2 zucchini between the prepared pans.
4. Season the zucchini by sprinkling ½ teaspoon garlic powder, 1 teaspoon oregano, Kosher salt, and black pepper over the slices. Toss gently to coat.
5. Arrange in a single layer, ensuring none of the slices overlap. This step is essential for achieving crisp chips.
6. Lightly spray with avocado oil spray once more to encourage browning.
7. Sprinkle 2/3 cup grated parmesan cheese evenly over the zucchini slices.
8. Bake for 15–17 minutes, until the zucchini chips are golden and slightly crispy around the edges.
9. Remove from the oven and allow them to cool slightly before serving. This helps them firm up and enhances their crisp texture.

Serve warm and enjoy immediately for best texture.

FAQs

1. Why aren’t my zucchini chips crispy?

Overlapping slices or uneven thickness can cause sogginess. Always arrange in a single layer and slice evenly.

3. How thin should I slice the zucchini?

¼-inch slices work best for balanced tenderness and crisp edges.

If you are not keto or gluten-free, you can enjoy zucchini chips with breading or panko crumbs. Create an egg wash for coating before adding crumbs.

Ingredient Spotlight
