Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it to prevent sticking.
Wash and dry the sweet potatoes. Using a sharp knife, slice them into 1/8 to 1/4-inch thick rounds. Try to keep the thickness consistent so they bake evenly.
In a large bowl, combine olive oil, sea salt, black pepper, smoked paprika, and garlic powder. Add the maple syrup or honey and whisk briefly to combine.
Add the sweet potato slices to the bowl and toss gently until each slice is lightly coated with the oil and spice mixture.
Arrange the slices in a single layer on the prepared baking sheet, leaving a little space between them so hot air can circulate and promote crisping.
Bake for 18–25 minutes, flipping the slices halfway through. Baking time depends on slice thickness and your oven; look for golden-brown edges and tender centers.
If you prefer extra crispiness, turn on the broiler for 1–2 minutes at the end of baking, watching closely to avoid burning.
Remove from the oven and immediately sprinkle with a pinch more salt if desired. Toss with chopped fresh herbs and a squeeze of citrus for brightness.
Serve warm as a side, snack, or base for toppings like avocado, feta, or a dollop of Greek yogurt.
