What You’ll Need for Your Colcannon

For the Mashed Potatoes

  • 4 tablespoons unsalted butter, divided – Use part for cooking the vegetables and the rest for a rich finish.
  • 1/2 cup whole milk – Adds essential creaminess without making the mash too heavy.
  • 1/2 cup heavy cream – This is the key to making the mash extra rich and luxurious.

For the Cabbage & Scallion Mix

  • 4 medium scallions, thinly sliced – They provide a mild, fresh onion flavor that’s essential to traditional colcannon.
  • Freshly ground black pepper, to taste – Freshly grinding it just before serving gives the best aroma.

Thoughtful Tips for Special Diets

If you’re sugar-conscious or managing your blood sugar, you’ll be happy to know that this dish is naturally low glycemic. The primary ingredients are whole foods that provide steady energy. For even better glycemic control, you can make a couple of simple tweaks.

First, be sure to keep the potato skins on for extra fiber, which helps slow down sugar absorption. You could also substitute a portion of the russet potatoes with cauliflower for a lower-carb version. Finally, this is a naturally diabetic-friendly recipe as written, with no added sugar.

My Pro Tips for the Best Colcannon

After making this Irish staple countless times, I’ve picked up a few tricks that make a big difference. These small adjustments ensure your Colcannon Mashed Potatoes turn out perfectly every single time.

  • Flavor Swap: For a deeper flavor, try using kale instead of cabbage. It’s a common variation in some Irish regions and adds a lovely, earthy note.
  • Diet Tweak: To make this dish vegan, use plant-based butter and a rich, unsweetened plant milk like oat or cashew. The result is just as creamy and satisfying.
  • Texture Fix: Always drain the cooked potatoes well and let them steam dry in the hot pot for a minute. This prevents watery mashed potatoes and gives you the perfect, fluffy base for your loaded mashed potatoes or this colcannon.
  • Storage Tip: If you have leftovers, they reheat beautifully. Add a splash of milk when reheating to bring back the creaminess. For more make-ahead strategies, my guide on make-ahead Thanksgiving sides has you covered.

Ingredients
  

Potatoes and Seasoning

  • 2 pounds russet potatoes, peeled and quartered
  • 1 teaspoon salt plus more for seasoning

Dairy

  • 4 tablespoons unsalted butter, divided
  • 1/2 cup whole milk
  • 1/2 cup heavy cream

Vegetables

  • 1 small head green cabbage, cored and thinly sliced about 4 cups
  • 4 medium scallions, thinly sliced

Seasoning

  • freshly ground black pepper, to taste

Instructions
 

  • Place the peeled and quartered potatoes in a large pot and cover with cold water by 1 inch. Add 1 teaspoon of salt to the water. Bring to a boil over high heat, then reduce the heat to medium and simmer for 15-20 minutes, or until the potatoes are very tender when pierced with a fork.
  • While the potatoes cook, melt 2 tablespoons of butter in a large skillet over medium heat. Add the sliced cabbage and cook, stirring occasionally, for 10-12 minutes until it is wilted and softened. Stir in the sliced scallions and cook for 1 minute more. Remove the skillet from the heat.
  • In a small saucepan, combine the whole milk and heavy cream. Warm over low heat until just steaming; do not boil. Keep warm.
  • Drain the cooked potatoes thoroughly and return them to the hot pot. Let them sit for a minute off the heat so any residual moisture evaporates.
  • Mash the potatoes with a potato masher until smooth. Gradually pour in the warm milk and cream mixture, stirring with a wooden spoon or rubber spatula until fully incorporated and the potatoes are creamy.
  • Gently fold the cooked cabbage and scallions into the mashed potatoes until evenly distributed. Season generously with additional salt and black pepper to taste. Transfer to a serving bowl, make a well in the center, and place the remaining 2 tablespoons of butter in the well to melt before serving.

Nutrition and Health Benefits

This dish is more than just comfort food; it’s a nourishing choice. Potatoes are a good source of potassium and vitamin C, while the cabbage contributes significant vitamin K and fiber. Together, they create a side dish that’s richer in nutrients than standard mashed potatoes.

The fiber from the cabbage supports digestive health and helps you feel full and satisfied. When you’re looking for other sides that pack a nutritional punch, my sweet potato salad is another great option.

A Lighter Version of Colcannon

If you want to lighten up this classic, it’s incredibly easy to do without sacrificing flavor. You can reduce the butter by a tablespoon or two and replace the heavy cream with additional whole milk. The result is still wonderfully creamy but a bit lighter.

For a different twist, you could even swap half the potatoes for cauliflower. It blends in seamlessly and adds extra vitamins. This is a great way to enjoy a lower-carb version of this traditional dish. For another light side dish idea, try my sweet potato and black bean salad.

Common Mistakes to Avoid for Perfect Colcannon

Even simple recipes can have pitfalls. Here’s how to avoid the most common issues people run into, so your Colcannon Mashed Potatoes turn out flawless.

Why are my mashed potatoes gluey? This usually happens from over-mashing. Use a potato masher or ricer, not a food processor, which can break down the starches too much. Stop mashing as soon as they are smooth.

How can I prevent watery colcannon? The key is to thoroughly drain the potatoes and let them steam dry. Also, make sure your cooked cabbage isn’t holding excess water; sauté it until nicely wilted.

Why is my dish bland? Don’t be shy with the seasoning! Potatoes need a good amount of salt. Always taste at the end and adjust the salt and pepper. The BBC Good Food guide to perfect mash has great general tips. For more holiday side dish guidance, my herb stuffing and grandma’s classic stuffing recipes cover common mistakes too.

I remember the first time I made this and under-salted it; it was such a easy lesson in how important seasoning is for simple ingredients!

How to Store and Enjoy Later

This dish stores wonderfully, which is great for meal prep. Let the colcannon cool completely before transferring it to an airtight container. It will keep in the refrigerator for up to 4 days.

Reheat it gently in a saucepan over low heat, stirring often and adding a splash of milk to bring back the creaminess. You can also reheat it in the microwave, covered, stirring every 30 seconds. For another side that stores and reheats well, try my cornbread stuffing.
