Cool strudels on a wire rack. Reheat within 2 hours or place cooled strudels in a covered container. Chill overnight. To reheat room temperature strudels, place strudels on a baking sheet lightly coated with nonstick cooking spray. Bake, uncovered, in a 350 degrees F oven for 10 minutes or until center is warm. Reheat chilled strudels using the same method but heat in a 400 degrees F oven for 10 minutes.
