Preheat your oven to 225°F (110°C).
Wash and dry the zucchinis.
Slice the zucchinis thinly (about 1/8 inch thick).
In a bowl, mix olive oil, garlic powder, onion powder, paprika, salt, and pepper.
Toss the zucchini slices in the oil mixture until evenly coated.
Arrange the slices in a single layer on baking sheets.
Bake for 20-25 minutes, flipping halfway through.
Keep an eye on them to prevent burning; they should be golden and crisp.
Remove from the oven and let cool for a few minutes.
Enjoy your crispy zucchini chips!
