A lighter Slow-Cooker Beef Casserole still needs the shape, aroma, and bite associated with the original. This recipe assigns a job to every ingredient: lean stewing beef, carrots, and celery set the structure; onion, barley, and tomato purée season it; beef stock and thyme finish it. The repeatable approach is to brown the meat and tomato purée first, transfer with measured stock, and slow-cook until barley and beef are tender, stopping once beef separates under a fork, barley is plump, vegetables hold shape, and no grease covers the gravy.

The change that makes it lighterSlow-Cooker Beef Casserole saves calories through control rather than omission: brown the meat and tomato purée first, transfer with measured stock, and slow-cook until barley and beef are tender. Keep tomato purée and thyme at their listed amounts and stop as soon as beef separates under a fork, barley is plump, vegetables hold shape, and no grease covers the gravy.
