These crispy, flavorful, gluten-free air fryer zucchini chips are a delicious snack or side dish. Coated in gluten-free breadcrumbs and cooked quickly in the air fryer, they develop a golden color and a satisfying crunch. Air frying uses far less oil than deep frying and makes cleanup easier, so these chips are an everyday-friendly option for a healthier treat.
I’m excited to share this zucchini chip recipe because it converted even picky eaters in my household. Zucchini can be a tough sell unless it’s in something sweet, so turning it into crisp, seasoned chips was a welcome change. These chips are perfect for gatherings, game day, or a simple after-school snack.
Air-fried zucchini chips are quick to prepare and crisp up well with just a light spray of oil. The breadcrumb coating locks in texture and flavor, while the air fryer keeps the result much lighter than traditional frying.
Ingredient Notes:
For exact amounts, see the recipe card below.
- Zucchini – Use zucchini or summer squash. Choose medium-sized squash for firm, even slices.
- Gluten-Free Breadcrumbs or Panko – Use store-bought gluten-free panko or regular gluten-free breadcrumbs. If you prefer, make your own from gluten-free bread.
- Nutritional Yeast – Adds a savory, cheesy note to the coating. Substitute grated Parmesan if you are not dairy-free.
- Egg – Helps the coating stick. Use an egg or a liquid egg replacer to make the recipe vegan.
- Salt and Pepper – Season to taste.
Substitutions
Common substitutions that work well:
- Replace nutritional yeast with grated Parmesan for extra savory flavor if dairy is acceptable.
- Use a liquid egg replacer (such as Just Egg) instead of an egg to make the recipe vegan.
How to Make Gluten-Free Air Fryer Zucchini Chips (Step-By-Step)
Step 1: Wash the zucchini and trim the ends. Slice into rounds about 1/4 inch thick. Pat the slices dry with paper towels to remove excess moisture and lightly sprinkle with salt. The salt helps draw out moisture so the chips get crispier.
Step 2: Combine the gluten-free breadcrumbs or panko, nutritional yeast, a pinch of salt, and pepper in a shallow bowl. Whisk to distribute the seasonings evenly.
Step 3: Beat the egg (or prepare the egg replacer) in a separate shallow bowl. Dip a few zucchini slices at a time into the egg, turning so each slice is fully coated.
Step 4: Transfer the egg-coated slices to the breadcrumb mixture and press gently so the coating adheres. Work in small batches to keep the coating consistent.
Step 5: Lightly spray the air fryer tray or basket with cooking oil. Arrange the coated zucchini slices in a single layer without overlapping. A light spray over the tops helps them brown and crisp.
Step 6: Air fry at 375°F (190°C) for about 10–12 minutes, flipping the slices halfway through (around 6 minutes) so both sides brown evenly. Cooking time will vary slightly with slice thickness and air fryer model.
Step 7: Remove chips when golden and crunchy. Cook remaining batches if necessary. Serve hot for the best texture and flavor.
Tips For Success
- Pat the zucchini slices dry before coating. Excess moisture prevents the coating from sticking and makes chips soggy.
- Don’t overcrowd the air fryer. Air circulation is essential for crisping.
- A light spray of oil on the tray and chips improves browning without adding much fat.
- Turn the chips halfway through cooking so both sides become evenly crisp.
- Use medium-thickness slices. Too thick and they won’t crisp; too thin and they can burn.
Yummy Dip Ideas
Dips make these chips even more fun. Try them with:
- Homemade marinara sauce
- Gluten-free ranch dressing
- Nacho cheese sauce
- Mild or spicy salsa
Frequently Asked Questions
Can these zucchini chips be made vegan? Yes. Use a liquid egg replacer instead of an egg and keep the nutritional yeast (or replace with a vegan seasoning blend).
Do I need to peel the zucchini? No. Keeping the skins on helps the slices hold their shape while cooking and adds color and nutrients.
Why flip the chips halfway through? Flipping ensures both sides brown and crisp evenly, especially in air fryers that heat from one direction more strongly.
How can I make them spicy? Add cayenne, chili powder, smoked paprika, or a dash of hot sauce to the egg or breadcrumb mixture for some heat.
Why are my zucchini chips soggy?
Soggy chips usually come from one or more of these issues:
- Excess moisture on the zucchini slices before coating.
- Overcrowding the air fryer basket, which blocks airflow.
- Insufficient oil spray to encourage browning.
- Slices cut too thick to crisp within the recommended time.
