• 2 cups chopped cabbage
• 1 cup broccoli florets
• 1 cup cauliflower florets
• 2 celery stalks, chopped
• 1 cup fresh spinach
• ½ medium onion, finely chopped
• 3 garlic cloves, minced
• 6 cups (1.4 liters) low-sodium vegetable or chicken broth
• ½ teaspoon dried thyme
• 1 teaspoon Italian seasoning
• ½ teaspoon paprika
• Salt and black pepper, to taste
• 2 tablespoons chopped fresh parsley
• 1 tablespoon lemon juice, optional

Optional for a Creamier Soup

• ¼ cup heavy cream
• ¼ cup grated Parmesan cheese

Instructions

1. Prepare the vegetables

Wash and chop the zucchini, cabbage, broccoli, cauliflower, celery, onion, and spinach.

2. Sauté the aromatics

Heat olive oil or butter in a large soup pot over medium heat. Add the onion and celery and cook for 3–4 minutes until softened. Add the garlic and cook for another 30 seconds.

3. Add the low-carb vegetables

Stir in the zucchini, cabbage, broccoli, and cauliflower. Cook for 2–3 minutes to bring out their flavor.

4. Add the broth and seasonings

Pour in the broth. Add the thyme, Italian seasoning, paprika, salt, and black pepper. Stir well and bring to a gentle boil.

5. Simmer the soup

Reduce the heat to low, cover partially, and simmer for 15–20 minutes, until the vegetables are tender.

6. Add spinach and optional cream

Stir in the spinach and cook for 2 minutes until wilted. For a creamy version, lower the heat and add the heavy cream and Parmesan. Warm gently without boiling.

7. Finish and serve

Add lemon juice and fresh parsley if desired. Taste and adjust the seasoning. Serve hot.

Tips for Keto Success

• Choose broth without added sugar or starch.
• Add shredded chicken or turkey for extra protein.
• For a thicker soup without flour, blend a small portion of the cooked cauliflower and stir it back into the pot.
