Ingredients & Instructions
Below is everything you need to create this warm and nourishing soup at home, along with tips to help you adjust the flavors and textures to your liking.
Ingredients
- 4 medium potatoes, peeled and diced
- 1 cup green cabbage, finely chopped
- 1 cup kale, stems removed and chopped
- 1 medium leek, sliced
- 1 onion, diced
- 3 cups vegetable broth
- 2 cups milk (or plant-based milk)
- 4 tablespoons butter (or vegan substitute)
- Salt and pepper, to taste
- ½ teaspoon nutmeg
- 2 green onions, sliced for garnish
Step-by-Step Instructions
1. Sauté the Aromatics
In a large pot, melt the butter over medium heat. Add the diced onion and sliced leek, cooking until soft, fragrant, and translucent. This step develops the base flavor of your soup.
Tip: Rinse leeks well—dirt often hides between the layers.
2. Add the Potatoes and Broth
Add the diced potatoes and stir for 2–3 minutes to lightly coat them in the butter and aromatics. Pour in the vegetable broth and bring the mixture to a gentle boil.
3. Add the Greens and Simmer
Reduce the heat to low and add the cabbage and kale. Let the soup simmer until the potatoes are fork-tender and the greens soften—usually about 15–20 minutes.
Tip: Keep the pot partially covered to prevent too much evaporation.
4. Blend to Your Preferred Texture
Use an immersion blender to puree the soup until smooth. If you prefer a rustic feel, leave some chunks of potatoes and greens for texture.
Alternative: Transfer portions to a blender carefully, blending in batches.
5. Add Milk and Seasonings
Pour in the milk and stir gently. Add salt, pepper, and nutmeg. Warm the soup through without letting it boil—this keeps it creamy and prevents the milk from separating.
6. Finish and Serve
Ladle the soup into bowls and garnish with sliced green onions for a fresh, vibrant touch. Serve hot with bread, crackers, or a side salad.
Cooking Tips & Variations
1. Choose the Right Potatoes
Starchy potatoes like russet or Yukon gold create a naturally creamy texture when pureed. Avoid waxy potatoes if you want a smoother consistency.
2. Make It Vegan
Simply replace:
- Butter → vegan butter
- Milk → almond, oat, or soy milk
Choose an unsweetened variety for best flavor.
3. Add More Flavor
- Stir in a clove of garlic, minced with the onions, for a deeper profile.
- Add a splash of cream (or coconut cream for dairy-free) for extra richness.
- For a smoky twist, add a pinch of smoked paprika.
4. Boost Nutrition
Enhance the soup with extra veggies like:
- Spinach
- Parsnips
- Celery
- Carrots
These blend in beautifully without altering the comforting flavor.
5. Adjust Thickness
If the soup becomes too thick, simply add more broth or milk. Too thin? Let it simmer uncovered to reduce.
Storage & Serving Suggestions
Storage
- Refrigerator: Store in an airtight container for up to 4 days.
- Freezer: Freeze for up to 3 months. Let it cool completely before freezing.
- Reheat: Warm gently on the stovetop over low heat. Add a splash of milk or broth if it thickens.
