Preheat your oven to 450°F (230°C) for optimal caramelization.

Peel and slice the yams or sweet potatoes into half-inch thick discs. Toss with olive oil, salt, and pepper in a large mixing bowl, then spread them on a baking sheet.

Bake the yams for 15 minutes, ensuring they are slightly firm to the touch.

Prepare the sweet and spicy glaze by mixing honey, brown sugar, cinnamon, and ground ginger in a small saucepan over low heat, stirring until well combined.

Coat the baked yams with the honey ginger glaze using a pastry brush.

If using, sprinkle pecans over the glazed yams.

Return to the oven and bake for an additional 10 to 15 minutes until golden brown and caramelized.

Transfer the yams to a serving platter and sprinkle with flaky salt before serving.
