Begin by heating your oven to 425°F. Prepare a baking sheet by covering it with aluminum foil, then fit a wire rack over the top.
Pat the chicken thighs thoroughly with paper towels to eliminate excess surface moisture.
Drizzle the olive oil over the thighs and generously coat them with the dry seasonings, salt, and pepper. Work the mixture into the skin by gently rubbing to ensure even coverage.
Arrange the thighs skin-side up on the wire rack. Roast them without covering for 35–40 minutes, or until an instant-read thermometer inserted into the thickest part registers 165°F.
If the skin hasn’t crisped to your preference, activate the broiler on high and place the tray back in for 2–3 minutes to finish.
