Traditional Irish Mashed Potatoes – A Hearty, Comforting Classic

If you’re seeking a warm, creamy, and deeply satisfying side dish, look no further than this authentic Irish Colcannon recipe. Perfect for family dinners or holiday gatherings, this iconic mashed potato dish, traditionally enjoyed across Ireland, blends fluffy russet potatoes with tender greens and rich dairy for a soul-nourishing experience. Whether you’re celebrating St. Patrick’s Day or simply craving comfort food, this easy Colcannon variation will hit the spot.

The Essence of Mashed Potatoes: What Makes It Special?

Colcannon is much more than just mashed potatoes. It’s a beloved Irish comfort food that combines creamy potatoes with vibrant greens like cabbage or kale, finished with a touch of butter and milk or cream for smooth richness. The result is a rustic yet refined dish, one that’s often served with a hearty knob of butter melting in the middle.

This recipe adds flexibility—you can use any dark leafy greens you have on hand, like Swiss chard, collard greens, or even spinach. With the mild heat from green onions and the buttery smoothness of russet potatoes, this dish becomes a comforting favorite.

Ingredients for the Perfect Mashed Potatoes

To make this traditional Irish side dish, you’ll need just a few simple pantry staples:

• 4 Russet Potatoes (2 to 2 ½ pounds): These starchy potatoes make the mash light and fluffy.

• Salt (to taste): Enhances all the natural flavors.

• 5 to 6 Tablespoons Unsalted Butter (plus extra for topping): Rich and creamy, butter is essential for that authentic taste.

• 3 Cups Chopped Leafy Greens (lightly packed): Kale, cabbage, chard, or other greens—choose your favorite or mix them.

• 3 Green Onions (minced, about ½ cup): Adds a mild onion flavor and freshness.

• 1 Cup Milk or Cream: Cream adds luxurious richness, but milk works beautifully for a lighter version.

Pro Tip: For a deeper flavor profile, try swapping half of the potatoes with parsnips. You can also mix in cooked crumbled bacon, thinly sliced leeks, or chopped chives for added layers of taste.

Step-by-Step Guide to Making Irish Mashed Potatoes 

1. Preparing the Potatoes – Boiling to Perfection

Start by peeling the russet potatoes and cutting them into 1½-inch chunks. Place them into a medium-sized pot and cover them with cold water. Add around 2 tablespoons of salt—this ensures the flavor soaks into the potatoes. Bring the water to a boil over high heat.

Continue boiling the potatoes until they are completely fork-tender, usually between 15 to 20 minutes depending on the size of your chunks. Once cooked, drain the potatoes in a colander and set them aside briefly.

2. Sautéing the Greens and Aromatics

Return the empty pot to the stove and set it over medium-high heat. Add 5 to 6 tablespoons of butter and let it melt until it’s gently bubbling. Toss in the chopped leafy greens and stir them occasionally as they cook. In about 3 to 4 minutes, the greens should be wilted and aromatic.

Now add the minced green onions and cook for another minute. Their fresh, oniony brightness pairs perfectly with the rich greens and creates the perfect flavor base for your Colcannon.

3. Bringing It All Together – Mashing the Magic

Once the greens are cooked, pour in the milk or cream and stir to combine. Then add the drained potatoes to the pot. Reduce the heat to medium.

Using a potato masher or a sturdy fork, mash the potatoes directly into the greens and milk mixture. Mix thoroughly until everything is well combined and has a rich, creamy texture. Taste the mash and adjust the salt if necessary.

Spoon the Colcannon into a serving dish or individual bowls, and place an extra dollop of butter on top for that authentic finish.

Why This Irish Mashed Potatoes Recipe Stands Out

This version of Colcannon stays close to the traditional Irish recipe while offering flexibility for modern tastes. It’s incredibly simple to make, yet full of rich, comforting flavors. The blend of creamy mashed potatoes, sautéed greens, and gentle onion gives it a unique character that’s ideal for everything from weeknight dinners to festive holiday meals.

You’ll also appreciate the customizable nature of this dish—whether you use kale, cabbage, or spinach, it adapts beautifully to what’s in your fridge.

Variations You Can Try

• Add Protein: Stir in crumbled bacon or diced cooked ham for a heartier version.

• Go Low-Carb: Use cauliflower instead of potatoes for a lighter option.

• Make It Vegan: Swap dairy butter and cream with plant-based alternatives like oat milk and vegan butter.

Storage and Reheating Tips

Store leftover Colcannon in an airtight container in the refrigerator for up to 3 days. Reheat on the stove or in the microwave with a splash of milk to restore creaminess. Avoid freezing, as the texture of mashed potatoes may change.

Simple and Traditional Mashed Potatoes Recipe

Prep Time: 10 mins
Cook Time: 25 mins
Total Time: 35 mins
Servings: 4 to 6 servings

Ingredients:
4 russet potatoes (2 to 2 1/2 pounds), peeled and cut into 1 1/2-inch pieces
Salt, to taste
5 to 6 tablespoons unsalted butter, plus more for serving
3 lightly packed cups chopped kale, cabbage, chard, or other leafy green
3 green onions, minced (about 1/2 cup)
1 cup milk or cream

Instructions:
Place the peeled and chopped potatoes into a medium-sized pot. Fill with enough cold water to cover the potatoes by at least one inch. Add 2 tablespoons of salt to the water to season the potatoes as they cook. Bring the pot to a boil over high heat. Once boiling, reduce the heat slightly and let the potatoes cook until completely fork tender, about 15 to 20 minutes. Once soft, drain the potatoes using a colander and set them aside.

Return the empty pot to the stove over medium-high heat. Add the butter and let it melt completely. Once the butter is hot and slightly bubbling, add the chopped greens. Stir and cook the greens for about 3 to 4 minutes until they are fully wilted and have released some of their natural moisture. Add the minced green onions and cook for another minute, just until fragrant and tender.

Reduce the heat to medium, then pour in the milk or cream. Stir gently to combine with the greens and onions. Add the drained potatoes back into the pot. Using a potato masher or fork, mash the potatoes directly into the buttery greens mixture. Mix thoroughly until the texture is creamy and everything is evenly combined. Taste and add additional salt if needed.

Scoop the finished Colcannon into a serving bowl or onto plates, and top each portion with an extra pat of butter to melt into the warm mash. Serve hot as a hearty side dish with meat, fish, or on its own.
