Preheat your oven to 400°F (200°C).
Slice the sweet potatoes into 1/4-inch rounds and pat them dry with a paper towel.
Toss the slices with olive oil, salt, and pepper, ensuring they’re evenly coated.
Spread the slices out in a single layer on a parchment-lined baking sheet.
Bake for 15 minutes, then flip each slice and bake for another 10–15 minutes, until tender and slightly crispy around the edges.
While the sweet potatoes are roasting, prepare your desired toppings. Chop herbs, sauté vegetables, or mix spreads as needed.
After roasting the sweet potatoes, let them cool for a few minutes.
Add a dollop of your chosen spread (like hummus or cream cheese) to each slice.
Layer additional toppings like avocado, pomegranate seeds, or nuts.
Finish with a drizzle of balsamic glaze or a sprinkle of fresh herbs.
Arrange the sweet potato crostini on a serving platter and enjoy immediately.
