When making homemade breakfast potatoes in the air fryer, the best potatoes are starchy and firm, as they will hold their shape well during cooking and provide a nice crispy texture on the outside.  Yukon Gold Potatoes: Yukon Gold potatoes are my favorite. They have a creamy texture and hold their shape nicely as they cook. They have some starch, so they get nice and crispy as they air fry.  Russet Potatoes: Idaho russet potatoes are great for seasoned home fries because of their high starch content. They have a nice, fluffy texture and turn crispy once cooked.  Air fryer red potatoes are another option, although they are less starchy than russets and Yukon gold potatoes; as a result, they might not get quite as crispy.
