Mediterranean Lean Beef Slow Cooker Vegetable Soup
Slow cooking lean sirloin allows the meat to soften gently while soaking up the aromatics from chopped onion, celery, carrots, and dried oregano. As the diced tomatoes break down into the beef broth over several hours, they create a light yet deeply savory base with clean Mediterranean flavors. Everything gathers in the slow cooker bowl at once, making prep straightforward with minimal cleanup. The result is a comforting, broth-forward vegetable soup that feels wholesome without requiring complex kitchen steps.
Why this one works
- Requires only ten minutes of hands-on knife prep before the slow cooker takes over.
- Lean sirloin becomes tender and shreds slightly after hours of gentle heat.
- The combination of canned tomatoes, beef broth, and oregano forms a balanced, herb-scented broth.
- Carrots, celery, and onions provide natural sweetness and pleasant vegetable texture.
What you’ll need
- 1 lb (450g) lean beef sirloin, cubed Cut into uniform bite-sized pieces so the meat cooks evenly throughout the long simmer.
- 2 cups (300g) diced carrots Slice into medium dice so they soften nicely without losing structure.
- 1.5 cups (200g) chopped celery Provides a traditional aromatic foundation that melds directly into the broth.
- 1 cup (150g) chopped yellow onion Softens completely to lend subtle natural sweetness to the liquid.
- 2 cups (480ml) beef broth Forms the savory liquid base alongside the juices from the canned tomatoes.
- 1 can (400g) diced tomatoes Pour in both the tomatoes and their packing liquid to enrich the overall flavor.
- 1 tsp (5g) dried oregano Infuses the broth with a warm, earthy Mediterranean herbal note.

Ways to make it your own

Serving suggestions
