With St. Patrick’s Day right around the corner, everyone’s thinking about corned beef and cabbage and maybe colcannon on the side.

Since corned beef and cabbage is pretty much the quintessential Irish comfort food, it kinda speaks for itself but you might know about colcannon.

What is Colcannon?

Colcannon is a traditional Irish side dish made up of creamy, whipped mashed potatoes with a healthy helping of greens like kale or green cabbage stirred in. 

But here we’ve turned the traditional Irish mashed potatoes into a soup with a rich broth full of hunks of potatoes, sliced leeks, chopped kale leaves, and even chopped green cabbage.

Ingredients

To make this you’ll need:

  • Butter– To saute the vegetables in
  • Leeks– Sliced, soaked, and rinsed
  • Greens– Chopped green cabbage and roughly chopped kale with the stems removed
  • Russet potatoes– Peeled and diced
  • Broth– Chicken broth. You can use vegetable stock if you want to keep this vegetarian.
  • Seasonings– Bay leaves, salt, black pepper
  • Heavy cream– Don’t substitute for a lower fat dairy product here
  • Green onions– Thinly sliced

How to Make

Making colcannon soup is easy!

Just melt the butter in a dutch oven over medium heat.

When the butter is melted, stir in the leeks, cabbage, and kale.

Turn the heat down to low, cover the pot and cook until the greens wilt, about 12 minutes or so,

Then add the potatoes, broth, bay leaves to the dutch oven.

Bring the soup to a simmer and keep simmering until the potatoes are fork tender and starting to fall apart, about 15 to 20 minutes.

Stir in the salt, pepper, cream, and green onions.

Use an immersion blender to puree some of the soup for a thick, creamy texture.

Ladle the soup into bowls and serve with a piece of good, crusty bread.

Enjoy!

Tips and Tricks

  • Don’t have an immersion blender? Carefully scoop or pour about 1/3 of the soup into a blender and blend until it is pureed. Then stir it back into the rest of the soup.
  • Let the potatoes cook just past fork tender. You want them to be starchy and slightly falling apart.
  • The soup will thicken up in the fridge. When you reheat it, stir in extra broth to bring it back to your desired consistency.

  1. I love a comforting soup, and yours really delivers! With winter back in full spring, this is just perfect! Thank you for sharing your delicious soup at Fiesta Friday!

  2. 5 stars
    I made this recipe for St. Patrick’s Day 2024 since I don’t love corned beef, haha! It is VERY good, even without adding cream. It’s hearty and a great winter soup. I used smart balance spread for the butter, and I added more kale than called for, and pretty sure more potatoes, which I scrubbed and left unpeeled (for rustic look/vitamins in the peel). I let it simmer until the potatoes were pretty soft, then just mashed them lightly against the side of the pan to thicken it, but left most of the potatoes in chunks. I am adding this to my soup rotation and my St. Patrick’s Day dinner ideas! This was simple, healthy, and delicious. We are looking forward to leftovers tonight!
