There’s something magical about a bowl of soup that feels like a warm hug at the end of a long day—and Colcannon Soup delivers exactly that. Inspired by the traditional Irish dish made with mashed potatoes and greens, this soup takes those same humble ingredients and transforms them into a velvety, nourishing bowl of comfort.
Colcannon has deep roots in Irish cuisine and is often served during celebrations, especially around Halloween. Traditionally, it’s a rustic side dish made with mashed potatoes, cabbage, and butter. In this modern version, we turn that timeless favorite into a one-pot soup that’s as cozy as it is flavorful. With the sweetness of leeks, the earthiness of kale, and the creaminess of blended potatoes, every spoonful feels smooth, rich, and utterly satisfying.
Whether you’re craving something simple and hearty, trying to use up veggies in your fridge, or looking for a comforting seasonal recipe, this Colcannon Soup fits the bill perfectly. Let’s dive into a delicious bowl of Irish-inspired comfort!
Recipe Overview

It delivers all the familiar flavors of traditional colcannon but in a warm, spoon-ready form. It’s nutrient-rich, customizable, and perfect for cold evenings or holiday gatherings.
Ingredients & Instructions
This easy recipe requires simple everyday ingredients—and the results are pure comfort.
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 alternative for dairy-free)
- 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, stirring occasionally. Cook until soft and translucent—this step builds a flavor base for the entire soup.
Tip: Be sure to wash leeks thoroughly; they often hide dirt between the layers.
2. Add the Potatoes
Stir in the diced potatoes and cook for 2–3 minutes to absorb the flavors. Pour in the vegetable broth, bring the mixture to a boil, then reduce the heat to a gentle simmer.
Let the potatoes cook until they begin to soften.
3. Add the Greens
Add the cabbage and kale to the pot. Simmer everything together until the potatoes are fully tender. The greens will wilt beautifully and add a mild, earthy flavor.
Tip: If you prefer a milder taste, use all cabbage or substitute spinach for kale.
4. Blend to Your Desired Texture
Once all the vegetables are tender, use an immersion blender to purée the soup. You can make it completely smooth or leave some small chunks for a rustic texture.
If you don’t have an immersion blender, carefully transfer the soup in batches to a regular blender.
5. Add the Milk and Seasonings
Stir in the milk, then season with salt, pepper, and the nutmeg, which adds a warm, subtle depth.
Heat the soup gently over low heat—avoid boiling to prevent the milk from curdling.
6. Serve and Garnish
Ladle the hot soup into bowls and garnish with sliced green onions. The fresh pop of flavor brightens the richness of the soup beautifully.
Cooking Tips & Variations
1. Make It Vegan
Swap out the butter for vegan butter and use plant-based milk such as oat or almond. Use a rich broth to maintain creaminess.
2. Add Protein
For a heartier soup, stir in cooked bacon, shredded chicken, or crumbled sausage before serving.
3. Texture Options
- Ultra-creamy: Blend completely until velvety smooth.
- Chunky: Blend only half the soup.
- Rustic: Mash lightly with a potato masher instead of blending.
4. Flavor Enhancements
- Add roasted garlic for depth.
- Stir in a splash of cream for extra richness.
- Top with cheese such as cheddar or parmesan.
5. Use Different Greens
Feel free to use spinach, Swiss chard, or Napa cabbage depending on what you have on hand.
