Dijon Herb Lean Beef Slow Cooker Vegetable Soup

Simmering lean beef low and slow gives tough cuts time to soften naturally while enriching the surrounding liquid. In this simple preparation, tangy Dijon mustard blends smoothly into the beef broth, cutting through the richness of the meat while thyme brings an earthy note to balance sweet carrots. Everything goes straight into the slow cooker with minimal prep, making it a reliable option when you want a warm, hands-off beef soup ready at dinner time.
Why this one works
- Lean beef chuck breaks down into tender bites over seven hours on low heat.
- Whisking Dijon mustard directly into the broth adds a gentle tang that balances the savory meat.
- Carrots lend natural sweetness and hold their shape during the extended cook time.
- Requires just ten minutes of prep before letting the slow cooker do the work.

What you’ll need
- 1 pound (450g) lean beef chuck, cubed Trim excess surface fat and cut into uniform bite-sized cubes for even cooking.
- 2 cups (300g) carrots, sliced Slice carrots evenly so they soften consistently without turning mushy.
- 3 tablespoons (45g) Dijon mustard Whisk thoroughly into the broth to prevent clumps and evenly distribute its sharp flavor.
- 1 teaspoon (5g) dried thyme Provides a warm, savory herb backbone that infuses the broth as it simmers.
- 4 cups (1 liter) beef broth Forms the liquid base of the soup; use a balanced beef stock or broth.
