- 1 large green cabbage, approximately 900 g–1.2 kg.
- 3 medium yellow onions.
- 3 cloves garlic, minced.
- 2 medium carrots, optional.

- ½ teaspoon black pepper.
- 1 teaspoon dried thyme.
- 1 teaspoon dried parsley.
- 1 bay leaf.
- ½ teaspoon paprika, optional.
- 1 tablespoon tomato paste, optional.
- 1 tablespoon lemon juice or apple cider vinegar, optional.
Vegetable broth is ideal for a vegetarian soup. Chicken broth can be used if you prefer a richer savory flavor.
3. Optional Ingredients
For additional flavor and texture, you can add:
- 1 cup cooked white beans.
- 200 g cooked chicken, shredded.
- 1 small zucchini.
- ½ teaspoon smoked paprika.
- 1 tablespoon Worcestershire sauce, if not making a vegetarian version.
- Fresh parsley for garnish.
- Grated Parmesan cheese for serving.
Equipment
You will need:
- A slow cooker or crockpot.
- A large cutting board.
- A sharp knife.
- A large spoon.
- Measuring cups and spoons.
- A ladle.
- A large bowl for preparing the vegetables.
If you do not have a slow cooker, you can prepare this soup in a large pot on the stove.
Instructions and Methods
Step 1: Prepare the Cabbage
Begin by removing any damaged outer leaves from the cabbage.
Wash the cabbage thoroughly under cool running water.
Place it on a clean cutting board.
Cut the cabbage into quarters.
Remove the hard central core from each quarter.
Slice the cabbage into thin strips or bite-sized pieces.
The pieces do not need to be perfectly uniform, but keeping them reasonably similar in size helps them cook evenly.
Place the chopped cabbage in a large bowl.
Why cabbage is perfect for soup
Cabbage has a mild flavor when raw, but it becomes softer and sweeter as it cooks.
Slow cooking allows the cabbage to absorb the flavors of the broth, onions, garlic, and herbs.
This creates a tender vegetable that is delicious and comforting.
Step 2: Slice the Onions
Peel the onions and cut them in half.
Slice them into thin strips.
You can use yellow onions, white onions, or sweet onions.
Yellow onions are particularly good because they develop a rich flavor when cooked.
If you prefer a stronger onion taste, you can use four onions instead of three.
Place the sliced onions in a bowl.
Step 3: Prepare the Carrots and Potatoes
If using carrots, wash and peel them.
Cut them into thin rounds or small pieces.
If using potatoes, wash, peel, and cut them into small cubes.
The potatoes should be similar in size so they cook evenly.
Carrots and potatoes are optional, but they add variety to the soup and make it more satisfying.
Step 4: Prepare the Garlic
Peel the garlic cloves.
Mince them finely.
Fresh garlic gives the soup a wonderful aroma and savory flavor.
You can use more or less garlic according to your preference.
For a milder flavor, use two cloves.
For a stronger garlic flavor, use four cloves.
Step 5: Sauté the Onions and Garlic
This step is optional but highly recommended for better flavor.
Heat the olive oil or butter in a skillet over medium heat.
Add the sliced onions.
Cook for approximately 5–8 minutes, stirring occasionally.
The onions should become soft and translucent.
Add the minced garlic.
Cook for another 30–60 seconds.
Be careful not to burn the garlic.
You can also add the tomato paste and stir for 1 minute.
The tomato paste adds depth and a little color to the broth.
Why sautéing helps
Sautéing the onions before slow cooking helps develop their natural sweetness and savory flavor.
Although you can place everything directly into the slow cooker, this extra step creates a richer-tasting soup.
Step 6: Add the Ingredients to the Slow Cooker
Place the chopped cabbage into the slow cooker.
Add the cooked onions and garlic.
Then add the carrots and potatoes, if using.
Pour in the vegetable or chicken broth.
Add the salt, black pepper, thyme, parsley, bay leaf, and paprika.
Stir gently to combine everything.
The cabbage may seem to fill the slow cooker at first, but it will shrink considerably as it cooks.
Do not overfill your slow cooker. Keep the contents within the manufacturer’s recommended maximum fill level.
Step 7: Slow Cook the Soup
Cover the slow cooker with its lid.
Cook on:
Low: 6–8 hours.
High: 3–4 hours.
The soup is ready when the cabbage is tender and the potatoes, if included, are fully cooked.
Cooking times vary depending on the size of the vegetables and the slow cooker model.
For the texture shown in the picture, cook until the cabbage is soft but still has some shape.
If you prefer very soft cabbage, continue cooking until it reaches your desired texture.
Stir gently near the end of cooking if needed.
Step 8: Taste and Adjust the Seasoning
When the soup is cooked, remove the bay leaf.
Taste the broth.
Add more salt or pepper if needed.
You can also add:
- A squeeze of lemon juice.
- A splash of apple cider vinegar.
- A little extra thyme.
- Fresh parsley.
- A pinch of paprika.
A small amount of lemon juice or vinegar can brighten the flavor of the cabbage and onions.
Do not add too much at once. Start with a teaspoon and adjust gradually.
Step 9: Serve the Soup
Ladle the hot soup into bowls.
Garnish with fresh parsley if desired.
Serve with warm bread, toast, or crackers.
The soup can be enjoyed as a starter or as a main meal with additional ingredients such as beans, chicken, or potatoes.
For a richer finish, add a little olive oil or grated Parmesan cheese.
Alternative Method: Stovetop Cooking
If you do not have a slow cooker, you can make this recipe in a large pot.
Instructions
- Heat olive oil or butter in a large pot.
- Add the sliced onions and cook for 5–8 minutes.
- Add the garlic and cook briefly.
- Add the cabbage, carrots, and potatoes.
- Pour in the broth.
- Add the herbs and seasonings.
- Bring the soup to a gentle boil.
- Reduce the heat and cover the pot.
- Simmer for approximately 30–45 minutes, or until the vegetables are tender.
- Remove the bay leaf, taste, and adjust the seasoning.
The stovetop method is faster, while the slow cooker provides a longer, gentler cooking process.

Tips for Perfect Results
1. Cut the cabbage evenly
This helps the pieces cook at a similar rate.
2. Do not overfill the slow cooker
Follow the recommended fill level for your appliance.
3. Sauté the onions first
This creates a richer flavor.
4. Use fresh cabbage
Fresh cabbage provides a better texture and flavor.
5. Add the right amount of broth
The broth should cover most of the vegetables without making the soup excessively watery.
6. Taste before serving
Adjust the salt, pepper, and acidity according to your preference.
7. Remove the bay leaf
Do not leave the bay leaf in the finished soup.
8. Add delicate herbs at the end
Fresh parsley can be added just before serving for a fresher flavor.
Storage and Reheating
Allow the soup to cool slightly after cooking.
Transfer leftovers into shallow airtight containers and refrigerate promptly.
Use within 3–4 days.
To reheat, place the soup in a saucepan and heat until steaming hot throughout.
You can also reheat individual portions in the microwave using a microwave-safe bowl.
If the soup becomes too thick after refrigeration, add a little broth or water.
Freezing
Cabbage soup can be frozen in suitable airtight containers.
Leave a little space at the top because the liquid expands as it freezes.
Thaw in the refrigerator and reheat thoroughly.
Potatoes may change texture slightly after freezing, but the soup will still be enjoyable.
