Preheat your oven to 225°F (107°C) and line a baking sheet with parchment paper.
Slice zucchinis thin—like, therapy-session thin—using a knife or mandoline.
Place slices on paper towels and press gently to remove excess moisture (don’t skip or you’ll get floppy sadness chips).
In a bowl, toss zucchini slices with oil, salt, pepper, garlic powder, and paprika if using.
Spread slices in a single layer on the baking sheet—no overlap, they need personal space.
Bake for about 2 hours, flipping halfway through.
Let chips cool completely to crisp up.
Try not to eat them all at once. (You will. It’s fine.)
