This scrumptious Colcannon recipe variation is a warming, hug-in-a-bowl vegetable soup that you can feed to a crowd for very little cash.

Colcannon means “white cabbage” in Irish. And it’s common to see the name applied to a beloved Irish mashed potatoes side dish. This soup has essentially the same ingredients, but becomes a complete and filling meal.

I’m so excited about this new vegetable soup recipe! The main reason is that I LOVE have a healthy admiration for potatoes. Every shape, color and cooking method of potatoes. From my childhood they have been a centerpiece of the most special family meals.

The only time I have ever been disappointed by a potato was in potato soup. And that can be put down to something I have already shared with you over and over, again — unpleasant texture. I think I just don’t appreciate creamy soups that are all one thick, smooth consistency.

I prefer soups to be a little more on the brothy side, even if the broth is creamy. Plus vegetable soup, and almost every other dish, needs a great variety of textures to be really pleasing and interesting to my apparently texture-snobbish palate.

But friends, my disdain for potato soup is over. This recipe for Colcannon Soup ticks all the right boxes with it’s rich, creamy broth and rustic chunks of potato, cabbage and green onions.

Now, I have a potato soup that I absolutely adore and I think you and your family will love it, too. Serve it with warm, crusty, 30-minute Soda Bread and you will be in comfort food heaven. Enjoy!

The Ingredients

Vegetable Stock: I highly recommend my homemade vegetable stock, but your favorite commercial brand will work. You will probably need to zhuzh it up a bit to get the best flavor. That’s okay, because we’ll use some vegetable base, too.

Also, if you don’t care about making this soup completely vegetarian, you could use chicken broth. It’s just as delicious!

Potatoes: I use baby potatoes in this recipe because I like the quick and easy prep, plus the color and the texture of leaving them skin-on. I mix red and gold varieties for the added color.

Cabbage: The namesake in this yummy Colcannon recipe. White cabbage (I call it green.)

Green Onions: Even though there are red onions in the soup base, green onions bring a unique, fresh flavor and bright pops of color. They’re often included in Colcannon.

Aromatics: That essential flavor base that brings rich, savory goodness to meat-based or vegetable soup always starts with red onions and carrots.

Seasonings: Caraway seeds are a delicious pairing with cabbage. And, they add a uniquely delightful flavor to this yummy potato soup. Garlic is the final boost of flavor from seasonings in this recipe for Colcannon.

Heavy Whipping Cream: Just 1/2 cup in the entire pot adds a creamy, unctuous richness to the broth. I suppose you could leave it out, but in my opinion, it takes this Colcannon recipe over the top.

Vegetable Base: Optional. Only use this if you think your broth needs an extra boost of flavor. Better than Bouillon is my go-to for great flavor in soups, stocks and gravies. And as I mentioned previously, if you don’t care about the soup being vegetarian you can easily sub chicken stock and chicken base in this recipe.

FAQs About Colcannon Soup

Can Colcannon Soup be frozen to use later?

No. Unfortunately, cooked potatoes don’t freeze well. They soak up even more moisture as they thaw and can become very grainy and unpleasant in texture.

In addition, dairy separates and loses its creamy consistency in the freezer. So, the cream in the broth also prevents this from being a good recipe for the freezer.

How Long Can I Keep Potato Soup (Colcannon Soup) in the refrigerator?

The leftovers will keep 4-5 days in the fridge. Seal it in an airtight container being careful to press out as much air as possible.

What Protein can I add if I want this recipe for Colcannon Soup to have meat?

Colcannon in it’s traditional mashed potato form is often served alongside “bangers” (sausages). Slicing up your favorite sausages and tossing them in the pot would be delicious. I think ham or chicken would also be tasty options.

How to Make the Recipe for Colcannon Soup

  1. Finely mince the onion and carrots. (I actually tossed mine into the food processor and ground them to a fine mince.) Halve the baby potatoes and chop the cabbage and green onions.
  2. Put a couple Tablespoons of avocado oil (or your oil of choice) into a large soup pot. Be sure the pot holds at least 6 quarts.
  3. Heat the oil over medium-high heat and then add the minced carrots and onions. Saute them quickly for 1 to 2 minutes to bring out the natural sugars and allow them to begin to soften, slightly.
  4. Add the halved baby potatoes, garlic, caraway seed and vegetable broth to the stock pot. Give everything a stir and then bring it all to a boil.
  5. Once the stock is boiling reduce the heat to medium and continue cooking until the potatoes are fork tender.
  6. When the potatoes are tender, taste the broth. If it needs a flavor boost, this is the time to add the vegetable base.
  7. Add the cabbage and green onions. Stir them in to the soup and continue to cook for only 3 to 5 minutes. This is my own personal preference. You can leave the soup on the heat longer if you like the cabbage to be very soft. We like it hot all the way through, but still with some bite to it — tender-crisp. Even after you remove the soup form the heat, the cabbage will continue to soften in the hot broth.
  8. Stir in the cream and your Colcannon soup is ready to serve.

  1. One of my family’s favorite meals is soup with bread. I made this, but added a pound of beef to fill up my hungry kids, and it was perfect. We had it with sourdough rye bread, and the flavor combinations were perfect.
