- 1/2 teaspoon dried oregano
- 1 bay leaf
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper

Instructions
Step 1: Sauté the Aromatics
Place the large stockpot over medium heat. Add the olive oil and allow it to heat for about 30 seconds until it shimmers. Add the diced onion and cook, stirring occasionally with a wooden spoon, for 5 to 7 minutes. The onion should become translucent and soft, but not brown. Add the minced garlic and cook for 1 more minute, stirring constantly, until fragrant. This step builds a flavor foundation. Tip: Do not rush this step; properly softened onions release natural sugars that enhance the soup’s depth.
Step 2: Add and Soften the Hard Vegetables
Add the sliced carrots and celery to the pot. Stir to combine with the onions and garlic. Cook for 5 minutes, stirring every minute or so. The vegetables will begin to soften slightly and brighten in color. This brief cooking period helps them start to break down before the liquid is added, ensuring they cook evenly and retain some texture in the final soup. The goal is not to brown them, but to warm them through.
Step 3: Incorporate Cabbage and Tomatoes
Add the chopped cabbage to the pot. It will seem like a large volume initially. Stir it into the other vegetables and cook for 3 to 4 minutes, just until the cabbage begins to wilt and reduce in volume by about one-third. Then, add the entire can of diced tomatoes with their juices. Stir well to combine. The tomatoes add acidity and body. Tip: Using undrained canned tomatoes provides liquid and helps prevent sticking at this stage.
Step 4: Simmer the Soup
Pour in the 8 cups of low-sodium vegetable broth. Add the dried thyme, dried oregano, bay leaf, kosher salt, and black pepper. Stir thoroughly to distribute the seasonings. Increase the heat to high and bring the soup to a boil. Once boiling, immediately reduce the heat to low to maintain a gentle simmer. Cover the pot with a lid, leaving it slightly ajar to allow some steam to escape. Simmer for 25 to 30 minutes. The soup is ready when the cabbage is completely tender and the carrots are easily pierced with a fork.
Step 5: Final Adjustments and Serving
After simmering, turn off the heat. Carefully remove and discard the bay leaf. Taste the soup and adjust seasoning if needed—you may want to add another 1/4 teaspoon of salt or pepper. Ladle the hot soup into bowls. Garnish each serving with a sprinkle of fresh chopped parsley. Tip: For best flavor, let the soup rest off the heat, covered, for 10 minutes before serving. This allows the flavors to meld further.
Tips and Tricks
For a richer flavor, consider browning the onion slightly in step one before adding the garlic. If you prefer a thicker soup, you can blend one to two cups of the finished soup with an immersion blender directly in the pot, then stir it back in. To make this soup ahead, prepare it completely, let it cool to room temperature, and store it in airtight containers in the refrigerator for up to 4 days. The flavors often improve on the second day. When reheating, you may need to add a splash of water or broth if it has thickened. For freezing, cool the soup completely and store in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
Recipe Variations
- Add Protein: Stir in 2 cups of cooked shredded chicken, 1 cup of cooked brown lentils, or 1 (15-ounce) can of rinsed white beans during the last 5 minutes of simmering.
- Spice It Up: Add 1/4 to 1/2 teaspoon of red pepper flakes with the dried herbs, or stir in 1 tablespoon of tomato paste with the aromatics for a deeper, slightly sweet note.
- Change the Broth: Use low-sodium chicken broth instead of vegetable broth for a different flavor profile.
- Extra Vegetables: Add 1 cup of sliced mushrooms with the carrots or 1 cup of frozen green peas during the last 5 minutes of cooking.
- Herb Finish: Substitute the parsley garnish with fresh dill, chives, or a squeeze of fresh lemon juice for brightness.
Frequently Asked Questions
Can I use a different type of cabbage? Yes. Green cabbage is standard, but savoy cabbage works well and has a more delicate texture. Red cabbage can be used but will turn the broth a purplish color. Avoid napa cabbage as it becomes too soft.
Is this soup freezer-friendly? Absolutely. Cool the soup completely and transfer it to airtight, freezer-safe containers, leaving about an inch of space for expansion. It will keep for up to 3 months. Thaw in the refrigerator overnight before reheating.
How can I make this soup more filling? Add a source of protein or complex carbohydrates. Stir in cooked shredded chicken, turkey, lean ground beef, lentils, quinoa, or beans during the last few minutes of cooking to warm through.
My soup tastes bland. What can I do? First, ensure you’ve added enough salt during cooking. If it’s still bland after seasoning, try adding a splash of vinegar (like apple cider vinegar) or a squeeze of lemon juice to brighten the flavors. A dash of soy sauce or Worcestershire sauce can also add depth.
Can I make this in a slow cooker? Yes. Sauté the onions, garlic, carrots, and celery as directed in a skillet, then transfer them to the slow cooker. Add all remaining ingredients except the parsley. Cook on LOW for 6-8 hours or on HIGH for 3-4 hours, until vegetables are tender.
Summary
This cabbage diet soup is a straightforward, nutritious option for meal prep. It relies on simple vegetables and broth, simmered into a satisfying meal. Customize it with proteins or spices to suit your taste.
