Recipe For Slow Cooker Vegetable Beef Soup

Step 1: Prep Your Ingredients

Start by preparing all your vegetables and meat. Ensuring everything is cut to a uniform size not only makes for a more aesthetically pleasing soup but also ensures even cooking. Tip: If you’re short on time, many grocery stores offer pre-cut vegetables in the produce section.

Step 2: Brown the Beef

Heat a skillet over medium-high heat and brown the beef pieces on all sides. This step isn’t strictly necessary but adds a depth of flavor to the soup that’s worth the extra effort. Once browned, transfer the beef to the slow cooker.

Step 3: Combine Everything in the Slow Cooker

Add all the remaining ingredients to the slow cooker with the beef. Stir well to combine. The liquid should just cover the ingredients; if not, add a bit more water or broth. Tip: For an extra flavor boost, consider using homemade beef broth.

Step 4: Cook Low and Slow

Cover and cook on low for 8 hours or on high for 4 hours. The soup is done when the beef is tender and the vegetables are cooked through. Tip: Resist the urge to stir the soup too often, as this can cause the vegetables to break down too much.

Step 5: Season and Serve

Once cooking is complete, taste the soup and adjust the seasoning with salt and pepper as needed. Serve hot, perhaps with a slice of crusty bread for dipping.

Tips and Tricks

For those looking to elevate their soup game, here are some advanced tips. First, consider searing the beef in batches to avoid overcrowding the pan, which can lead to steaming rather than browning. Second, adding a parmesan rind to the soup as it cooks can add a wonderful umami depth. Lastly, for a thicker soup, you can mash some of the potatoes against the side of the slow cooker before serving.

Recipe Variations

  • For a richer soup, substitute half of the beef broth with red wine.
  • Add a can of drained and rinsed kidney beans for extra protein and fiber.
  • Swap out the green beans for peas or corn for a different vegetable profile.
  • For a spicier version, add a diced jalapeño or a teaspoon of crushed red pepper flakes.
  • Use sweet potatoes instead of regular potatoes for a sweeter, more nutrient-dense option.
