Prep Time: 15 minutes Cook Time: 6–8 hours on LOW or 3–4 hours on HIGH Total Time: About 6–8 hours Servings: 6 Category: Soup / Side Dish Cooking Method: Slow Cooker

Ingredients

• 1 medium head green cabbage (about 2–2½ lb), chopped

• 2 large yellow onions, thinly sliced

• 3 cloves garlic, minced

• 6 cups low-sodium chicken or vegetable broth

• 2 tablespoons olive oil or melted butter

• 1 tablespoon Worcestershire sauce (optional)

• 1 teaspoon onion powder

• ½ teaspoon garlic powder

• ½ teaspoon dried thyme

• ½ teaspoon black pepper

• ½ teaspoon paprika (optional)

• 1 bay leaf

• Salt to taste

• 1 tablespoon lemon juice or apple cider vinegar (optional)

• 2 tablespoons fresh parsley, chopped (optional)

Instructions

Step 1: Prepare the vegetables

Remove the tough core from the cabbage and chop it into bite-sized pieces. Peel and thinly slice the onions, then mince the garlic.

Step 2: Add everything to the slow cooker

Place the cabbage, sliced onions, and garlic into the slow cooker. Pour in the broth and olive oil. Add the Worcestershire sauce, onion powder, garlic powder, thyme, black pepper, paprika, and bay leaf.

Step 3: Mix and cover

Stir the ingredients gently so the cabbage and onions are coated with the broth and seasonings. The cabbage may fill the cooker at first, but it will shrink as it cooks.

Step 4: Slow cook

Cover and cook on LOW for 6–8 hours or HIGH for 3–4 hours, until the cabbage and onions are soft and tender. Cooking times vary by slow cooker.

Step 5: Finish the soup

Remove the bay leaf. Taste and add salt if needed. Stir in lemon juice or apple cider vinegar for a brighter flavor.

Step 6: Serve

Ladle into bowls and garnish with fresh parsley. Serve warm with toasted bread or alongside grilled chicken.

Q/S — Questions & Tips

Q: Can I make this soup on the stovetop? Yes. Combine the ingredients in a large pot, bring to a gentle boil, then cover and simmer for about 30–45 minutes, until the cabbage is tender.

Q: Can I add carrots or celery? Yes. Add 2 sliced carrots and 2 chopped celery stalks for extra flavor and vegetables.

Q: Can I add meat? Yes. Add cooked shredded chicken, browned ground beef, or sausage to make it more filling.

Q: How can I make the broth richer? Sauté the onions in olive oil for 8–10 minutes before adding them to the slow cooker. This develops a sweeter, deeper flavor.

Q: How do I store leftovers? Refrigerate in an airtight container for 3–4 days. Reheat thoroughly before serving.

Q: Can I freeze it? Yes. Cool the soup, portion it into freezer-safe containers, and freeze. The cabbage may become softer after thawing.

Chef’s Tip: Start with low-sodium broth and add salt at the end. This helps keep the soup flavorful without making it too salty.
