Instructions
- Heat olive oil in a large skillet over medium-high heat. Add the ground beef and cook, breaking it up with a spoon, until thoroughly browned. Drain off any excess fat.
- Add the chopped onion to the skillet with the browned beef and cook until softened, about 5-7 minutes. Stir in the minced garlic and cook for another minute until fragrant.
- Transfer the browned beef, onion, and garlic mixture to your slow cooker.
- Add the chopped cabbage, diced carrots, and diced celery to the slow cooker.
- Pour in the crushed tomatoes, diced tomatoes (with their juice), and beef broth.
- Stir in the dried oregano, dried thyme, salt, black pepper, and add the bay leaf.
- Stir all ingredients gently to combine.
- Cover the slow cooker and cook on LOW for 6-8 hours, or on HIGH for 3-4 hours, or until the cabbage is very tender and the vegetables are cooked through.
- Once cooked, remove and discard the bay leaf.
- Stir in the optional apple cider vinegar, if using, to brighten the flavors.
- Taste and adjust seasonings as needed, adding more salt or pepper if desired.
- Ladle the soup into bowls and garnish with fresh chopped parsley, if using. Serve hot.
Cooking Tips and Variations
For the best flavor, do not skip browning the ground beef and sautéing the onions and garlic before adding them to the slow cooker. This crucial step creates a flavorful base that significantly enhances the depth of the soup. Draining the excess fat from the beef also prevents the soup from becoming greasy. Cut your vegetables into roughly uniform sizes to ensure even cooking; for instance, if your carrots are cut too large, they might remain a bit firm while the cabbage is perfectly tender. If you prefer a richer, slightly smoky flavor, consider using fire-roasted diced tomatoes instead of plain diced tomatoes. For an extra layer of umami, a dash of Worcestershire sauce (about 1 teaspoon) can be added along with the broth. If you find the soup too thin, you can thicken it slightly by removing about a cup of broth, mixing it with 1-2 tablespoons of cornstarch until smooth, and then stirring it back into the slow cooker during the last 30 minutes of cooking. Conversely, if you prefer a thinner soup, simply add a bit more beef broth or water until it reaches your desired consistency.
This slow cooker cabbage soup is incredibly versatile. To make it vegetarian or vegan, simply omit the ground beef and use vegetable broth instead of beef broth. You can replace the meat with a can of drained and rinsed cannellini beans or kidney beans for added protein and fiber, or even some sliced mushrooms for a meatier texture. For a gluten-free version, this recipe is already naturally gluten-free, just ensure your beef broth is certified gluten-free if you have sensitivities. Spice lovers can add a pinch of red pepper flakes along with the other seasonings for a subtle kick. Other vegetables can also be incorporated; diced bell peppers, zucchini, or even a handful of spinach stirred in during the last 15-20 minutes of cooking would be delicious additions. For a creamier finish, a swirl of heavy cream or a dollop of sour cream can be added to individual servings right before eating, though this will increase the calorie and fat content. Serve this hearty soup with a side of warm crusty bread for dipping, or a sprinkle of grated Parmesan cheese for an extra savory touch. A squeeze of fresh lemon juice at the end can also brighten all the flavors beautifully.
Storage and Reheating
This Slow Cooker Cabbage Soup is excellent for meal prepping and makes a large batch, perfect for enjoying throughout the week. To store leftovers, allow the soup to cool completely to room temperature before transferring it to airtight containers. It can be stored in the refrigerator for up to 3-4 days. For longer storage, this soup freezes beautifully. Divide the cooled soup into individual freezer-safe containers or heavy-duty freezer bags, leaving a little headspace for expansion. It can be frozen for up to 3 months. Thaw frozen soup overnight in the refrigerator before reheating.
To reheat, you have several options. For individual portions, simply microwave on high in a microwave-safe bowl, stirring occasionally, until heated through. For larger quantities, transfer the soup to a saucepan or Dutch oven and reheat over medium heat on the stovetop, stirring frequently, until simmering and thoroughly hot. If the soup appears too thick after reheating, you can add a splash of beef broth or water to reach your desired consistency. Always ensure the soup is heated to an internal temperature of 165°F (74°C) for food safety. The flavors often deepen and meld even further after a day or two in the refrigerator, making this soup even more delicious as leftovers!
Frequently Asked Questions
Can I use different ground meat in this soup?
Absolutely! While lean ground beef is traditional and provides a robust flavor, you can easily substitute it with ground turkey, ground chicken, or even ground pork. If using ground poultry, be sure to brown it thoroughly to develop flavor, and you might need to add a bit more olive oil as it tends to be leaner. Adjust seasonings as needed to complement the chosen meat.
Do I have to brown the ground beef first?
While technically you can add raw ground beef directly to the slow cooker, it is highly recommended to brown it first. Browning the meat, along with sautéing the onions and garlic, creates a depth of flavor that significantly enhances the soup. This step also allows you to drain off excess fat, resulting in a less greasy and more flavorful broth. Skipping this step will result in a less rich and somewhat blander soup.
Can I add other vegetables to this slow cooker cabbage soup?
Yes, this soup is very adaptable to other vegetables. Feel free to add diced bell peppers, zucchini, green beans, or even a handful of fresh spinach during the last 15-20 minutes of cooking. Just be mindful of vegetables that cook very quickly, like spinach, and add them towards the end to prevent them from becoming mushy. Root vegetables like potatoes or sweet potatoes can also be added, diced into 1-inch pieces, at the beginning with the other vegetables.
How can I make this soup spicier?
If you enjoy a bit of heat, there are several ways to spice up this cabbage soup. You can add a pinch or two of red pepper flakes along with the dried herbs. For a more pronounced kick, a diced jalapeño or serrano pepper can be added with the onions and garlic during the initial browning step. Alternatively, you can stir in a dash of hot sauce to individual bowls before serving.
