Sweet potato toast is one of those ideas that sounds trendy but genuinely delivers — golden, tender planks with crispy edges that hold up beautifully under any topping you throw at them. The garlic-herb oil here is the real star: coconut oil, fresh rosemary, thyme, and a hint of ground ginger come together into something fragrant and deeply savory that soaks right into the sweet potato as it roasts. Because the whole recipe is built around whole, simple ingredients, there's no need to scan labels or second-guess anything hiding in a sauce or seasoning blend. Mushroom-based ingredients and umami boosters have quietly crept into a lot of packaged foods and restaurant dishes, so having a from-scratch recipe like this one is genuinely useful. The double-brush technique — coating both sides as you flip — means every bite gets full herb coverage rather than just a lightly seasoned surface. A quick broil at the end takes the edges from soft to just-golden, giving you that satisfying contrast of crisp outside and creamy interior. Finish with a scatter of fresh parsley and serve them straight from the pan while they're still warm.

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.
