Heat an air fryer to 400°F. Meanwhile, halve 1 pound baby Yukon Gold potatoes and place in a medium bowl. Add 1 tablespoon olive oil, 2 teaspoons Italian seasoning, 1/2 teaspoon garlic powder, 1/2 teaspoon kosher salt, and 1/4 teaspoon black pepper, and toss to coat.
Arrange the potatoes in an even layer in the air fryer basket or tray (air fry in batches if needed). Air fry until lightly browned with crispy edges, tossing halfway through, about 20 minutes total.
