Microwaveable packages having composite susceptors and methods for using same are provided. In a general embodiment, composite susceptors for cooking microwaveable foods (12, 14) in a microwave oven are provided. The composite susceptors may include, for example, a first layer that is a standard microwave susceptor (30) and a second layer (32) comprising mobile charges, wherein the second layer is at least substantially metal free. The second layer comprising mobile charges can both shield the standard susceptor from microwaves, and act as a conductor to increase the conductivity of the standard susceptor. The composite susceptors of the present disclosure provide improved surface heating patterns that are similar to surface heating patterns of conventional ovens, while also providing the benefits of microwave cooking.
