Preheat oven to 400 degrees F.

Dice potatoes and pat dry to remove excess water.

In a large bowl, toss potatoes with olive oil, minced garlic, garlic powder, onion powder, paprika, salt, and black pepper.

Spread potatoes in a single, even layer on a large rimmed baking sheet.

Bake in the center of the oven for 45 minutes, flipping halfway through, until deep golden brown and crispy.

In a small bowl, whisk together mayonnaise, sweet chili sauce, lemon juice, and rice vinegar (if using).

Transfer cooked potatoes to a serving dish and drizzle with bang bang sauce or serve as a dip.

Garnish with green onions and sesame seeds before serving.
