1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish or line it with parchment paper for easy cleanup.
2. In a medium saucepan, melt the butter over medium heat. Once melted, stir in the brown sugar, maple syrup (or honey), orange juice, cinnamon, nutmeg, vanilla extract, and salt. Cook, stirring frequently, until the sugar is dissolved and the mixture is smooth and bubbly, about 3-4 minutes.
3. Place the cubed sweet potatoes in the prepared baking dish. Pour the warm syrup mixture evenly over the potatoes, gently stirring to coat all the pieces.
4. Cover the dish tightly with aluminum foil and bake for 30 minutes. The foil helps the potatoes steam and soften evenly, which is key to that tender-yet-saucy texture.
5. Remove the foil and give the sweet potatoes a gentle stir. Sprinkle chopped pecans or walnuts on top, if using, then return the dish to the oven, uncovered, for another 15-20 minutes. This step caramelizes the syrup and adds a lovely golden glaze.
6. Check doneness by piercing a sweet potato cube with a fork—it should be tender but not mushy. If needed, bake for an additional 5-10 minutes uncovered.
7. Let the dish cool for a few minutes before serving. This allows the syrup to thicken slightly and cling beautifully to each bite.

One tip I’ve learned over the years is to resist the urge to stir too often during baking. Letting the syrup work its magic undisturbed creates that glossy finish and deep caramelization that everyone loves.
