Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.
Bring a large pot of salted water to a boil and add the sliced sweet potatoes. Cook for about 8-10 minutes until fork-tender. Drain and set aside to cool slightly.
Place the cooled sweet potato slices on the prepared baking sheet and gently press down each slice with a fork or the bottom of a glass until flattened slightly.
In a small bowl, mix together olive oil, maple syrup, chili paste, smoked paprika, salt, and pepper. Brush this mixture generously over each smashed slice.
Roast in the oven for about 25-30 minutes, flipping halfway through for even crispiness. They are done when golden brown and crispy around the edges.
Once out of the oven, sprinkle sesame seeds and fresh herbs over the smashed sweet potatoes. Optionally, squeeze lime juice on top.
Serve hot and enjoy as a side dish or snack.
