A frozen food package and method of producing and using the same is disclosed. The food package includes a bag which is freezable, ovenable and microwaveable. A frozen food assembly within the bag includes food (uncooked, cooked, or partially cooked), preferably an entree. Typically, the food assembly includes a meat, a fruit or vegetable, and a flavoring liquid such as a broth or stock, and may include infused oil or a dairy product. The food is typically embedded in the frozen liquid to facilitate handling and shipping and to align the frozen food with a display window of the bag. Chemical preservatives are not necessary and sauces may be omitted although sauces are not burned in the cooking process. The method typically includes sealing the frozen food in the liquid-impermeable bag and cooking the food in the sealed bag. The resulting dish is a substantial improvement over the well-known precooked frozen meals.
