🛒 Ingredients

• 1 medium head green cabbage, chopped
• 3 large yellow onions, thinly sliced
• 3 carrots, sliced
• 3 cloves garlic, minced
• 6 cups vegetable or chicken broth
• 1 can (14.5 oz) diced tomatoes, undrained
• 2 tbsp olive oil or butter
• 1 tsp dried thyme
• 1 tsp dried parsley
• ½ tsp paprika
• ½ tsp black pepper
• 1 tsp salt, or to taste
• 1 bay leaf
• 1 tbsp Worcestershire sauce, optional
• 1 tbsp lemon juice, optional
• Fresh parsley, for garnish

👩‍🍳 Instructions

1. Prepare the vegetables
Wash the cabbage and remove the tough outer leaves. Chop it into bite-sized pieces. Thinly slice the onions and carrots, then mince the garlic.

2. Add everything to the slow cooker
Place the cabbage, onions, carrots, and garlic into a 6-quart slow cooker.

3. Add the tomatoes and broth
Pour in the diced tomatoes and vegetable or chicken broth. Add the olive oil or butter.

4. Season
Add thyme, parsley, paprika, black pepper, salt, Worcestershire sauce, and the bay leaf. Stir gently to distribute the ingredients.

5. Slow cook
Cover and cook on LOW for 6–8 hours or HIGH for 3–4 hours, until the cabbage, onions, and carrots are tender.

6. Finish the soup
Remove the bay leaf. Taste and adjust the seasoning. For a brighter flavor, stir in a tablespoon of lemon juice just before serving.

7. Serve
Ladle the hot soup into bowls and garnish with fresh parsley. Serve with crusty bread or warm rolls.

⭐ Pro Tips

• Don’t worry if the slow cooker looks very full. Cabbage shrinks considerably during cooking.
• For deeper flavor, sauté the onions and garlic in butter for 5–7 minutes before adding them to the slow cooker.
• Add sliced mushrooms for extra savory flavor.
• For a heartier meal, add white beans, chickpeas, cooked chicken, or smoked sausage.
• If you like spicy soup, add a pinch of red pepper flakes.
• Want a thicker soup? Mash a small portion of the cooked vegetables against the side of the slow cooker and stir them back in.

🍽️ What to Serve With It

This soup pairs beautifully with:

• Crusty garlic bread
• Whole-grain rolls
• Grilled cheese
• Cornbread
• A simple green salad
• Roasted vegetables

🥡 Storage

Allow the soup to cool before transferring it to airtight containers. Refrigerate for 3–4 days. It can also be frozen for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop or in the microwave.
