Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
In a large bowl, toss the halved baby potatoes with olive oil, salt, and black pepper until evenly coated.
Spread the potatoes in a single layer on the prepared baking sheet. Roast in the preheated oven for 25-30 minutes, or until golden brown and crispy, flipping halfway through.
While the potatoes are roasting, in a small bowl, whisk together gochujang, rice vinegar, maple syrup, and sesame oil until smooth.
Once the potatoes are done, remove them from the oven and let them cool for about 5 minutes.
In a large mixing bowl, combine the roasted potatoes with the gochujang dressing. Gently toss to coat the potatoes evenly.
Add the sliced green onions, chopped cilantro, and toasted sesame seeds. Toss again to combine.
Serve warm or at room temperature.
