Preheat your oven to 225°F (110°C).
Wash and dry the zucchinis thoroughly.
Slice the zucchinis thinly, about 1/8 inch thick.
In a mixing bowl, combine the sliced zucchinis with olive oil, garlic powder, onion powder, paprika, salt, and pepper.
Toss the zucchinis to coat them evenly with the seasoning.
Line a baking sheet with parchment paper.
Arrange the zucchini slices in a single layer on the baking sheet.
Bake in the preheated oven for 25-30 minutes, flipping halfway through.
Monitor closely to prevent burning; they should be golden and crispy.
Remove from the oven and let cool before serving.
