Slow cooking is a method of preparing food at low temperatures over an extended period. This technique allows flavors to develop and ingredients to become tender, making it ideal for dishes like stews, soups, and casseroles. A slow cooker or crockpot is often used for this purpose, providing a convenient way to cook meals without constant supervision. The process typically involves placing ingredients in the cooker, setting the desired temperature, and letting it cook for several hours. This method not only enhances the taste but also helps retain nutrients, making it a popular choice for healthy meal preparation.
