Preheat your oven to 225°F (110°C). Line two baking sheets with parchment paper.
In a large bowl, toss the zucchini slices with salt and let them sit for about 10 minutes to draw out moisture. Pat them dry with paper towels.
In a separate bowl, mix the garlic powder, onion powder, paprika, and black pepper. Add the breadcrumbs to this mixture and stir to combine.
Drizzle the olive oil over the zucchini slices and toss to coat evenly. Then, dip each slice into the breadcrumb mixture, pressing lightly to adhere.
Arrange the coated zucchini slices in a single layer on the prepared baking sheets, making sure they do not overlap.
Bake in the preheated oven for about 2 hours, flipping the chips halfway through, until they are golden brown and crispy.
While the zucchini chips are baking, prepare the Greek yogurt ranch dip by combining the Greek yogurt, ranch seasoning, lemon juice, dill, salt, and pepper in a bowl. Mix well and refrigerate until ready to serve.
Once the zucchini chips are done, let them cool for a few minutes before serving with the ranch dip.
Notes
For extra flavor, add grated Parmesan cheese to the breadcrumb mixture.
Try using different seasonings like Italian herbs or Cajun spice for a unique twist on the chips.
