Croquettes are typically breaded bundles of vegetables or meat held together by a thick white sauce or bchamel and deep-fried. But in this version, the chicken croquettes are shaped, breaded and baked, making them lower in fat than traditional deep-fried croquettes. Prepare these easy chicken croquettes a few hours ahead of time, so the mixture will have plenty of time to chill and firm up before being formed and baked. Serve the chicken croquettes with a medium bchamel sauce (also known as a white sauce) and mashed potatoes.
