Sweet potatoes are naturally sweet on their own, and this recipe leans into that completely — no added sugars, syrups, or sweetened sauces anywhere in sight. Instead, the flavor comes from a fragrant blend of fresh rosemary, thyme, garlic, and a touch of ground ginger all whisked into melted coconut oil, which gets brushed generously onto each plank before roasting. The result is savory, herby, and deeply satisfying in a way that feels indulgent without any of the sugar-laden shortcuts. Slicing the sweet potatoes into thick planks and roasting them at high heat gives you tender centers with lightly golden, slightly crisp edges — especially if you hit them with a quick broil at the end. It's a genuinely clever swap for conventional toast, and the garlic-herb oil makes every bite taste intentional and bold. Scatter a little fresh parsley on top before serving and you've got something that looks as good as it tastes.

Preheat a toaster oven to 400°F (205°C), or set a conventional oven to 400°F (205°C) with a rack in the upper third. Line a baking sheet with parchment paper.
Trim the ends off each sweet potato and slice lengthwise into planks about 1/4-inch thick — aim for 4 planks per potato, each roughly the size of a slice of bread. Discard or reserve the rounded outer edge pieces for another use.
