Coat chicken and potatoes with oil using either a large bowl or a ziplock bag.
Sprinkle spices on chicken and potatoes
Line a half sheet pan with foil, arrange potatoes and chicken with room between the pieces. (Better with baking rack?)
Bake for 45 minutes to 1 hour (internal temp 165 is done)
Notes
Crowding too much in a pan generates too much juice and leave potatoes soggy. Try splitting chicken & potatoes when making large batches. Also try using a baking rack.
