Ingredients
  

  • 2 medium zucchini
  • 2 tablespoons olive oil (or avocado oil)
  • 1/2 cup finely grated Parmesan cheese (the powdery kind works best for coating)
  • 1/4 cup almond flour
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon smoked paprika (optional, for color and depth)
  • 1/4–1/2 teaspoon kosher salt, to taste
  • 1/4 teaspoon black pepper
  • Optional garnish: chopped fresh parsley or a squeeze of lemon
  • Optional dip: ranch, garlic aioli, or marinara (low-sugar)

Method
 

  1. Prep the zucchini: Wash and dry thoroughly. Slice into 1/8–1/4-inch rounds. Thinner slices get crisper; thicker ones are slightly more tender.
  2. Draw out moisture: Lay slices on a clean towel or paper towels. Sprinkle lightly with salt. Let sit 10–15 minutes, then gently pat dry. This step is key for crunch.
  3. Preheat and line: For oven, heat to 425°F (220°C) and line a baking sheet with parchment. For air fryer, heat to 375°F (190°C) and lightly oil the basket or use perforated parchment.
  4. Mix the coating: In a bowl, combine Parmesan, almond flour, garlic powder, onion powder, smoked paprika, salt, and pepper.
  5. Oil the slices: Toss zucchini rounds with olive oil until lightly coated. Don’t drench them—just a slick surface helps the coating stick.
  6. Coat for crispness: Press each slice into the Parmesan mixture, coating both sides. Shake off excess and set on the prepared sheet or air fryer basket in a single layer.
  7. Bake or air fry: Oven: Bake 15–20 minutes, flipping halfway, until golden and crisp at the edges.
  8. Air fryer: Cook 8–12 minutes, shaking or flipping at the halfway mark. Work in batches to avoid crowding.
  9. Finish and serve: Let chips cool 2–3 minutes to firm up. Sprinkle with a touch more Parmesan or parsley. Add a squeeze of lemon if you like. Serve with your favorite low-carb dip.
