Large slow-cookers accommodate turkey thighs, but oval-shaped cookers handle them the bet. Arrange the turkey thighs in a single layer to ensure even cooking.
Seasonings can fade after hours of slow cooking. To perk up flavor, sprinkle the sliced turkey with additional Cajun seasoning just before serving.
Seal any leftover turkey in a resealable plastic food storage bag and refrigerate it for up to two days.
