Ingredients You’ll Need
The magic of the Colcannon Irish Potato Recipe shines because of its straightforward ingredients, each playing a vital role in bringing out authentic flavors, textures, and that signature creaminess and slight bite from the cabbage and green onions.
- 2 lbs russet potatoes: These starchy potatoes give a fluffy, creamy base perfect for mashing.
- 4 tablespoons unsalted butter: Adds richness and silkiness to the potatoes, plus a little extra for finishing touches.
- 1/2 cup whole milk (or cream): For smooth, creamy mash with just the right amount of moisture.
- Salt and pepper: Simple seasonings essential for enhancing the natural flavors.
- 1 small head of cabbage, shredded: Provides a tender crunch and vibrant green bursts within the mash.
- 4 green onions, chopped: Adds freshness and mild onion flavor that brightens the dish.
- 1 tablespoon olive oil (or butter): For sautéing the cabbage, giving it a luscious texture and subtle caramelization.
How to Make Colcannon Irish Potato Recipe
Step 1: Cook the Potatoes
Place the peeled and cubed russet potatoes into a large pot and cover them with cold water, adding a pinch of salt for seasoning. Bring the water to a boil over medium-high heat, then let the potatoes cook gently until they are soft enough to pierce easily with a fork—this usually takes about 12 to 15 minutes. Perfectly cooked potatoes are the heart of this dish, so don’t rush this step!
Step 2: Mash the Potatoes
Drain the potatoes thoroughly and return them to the pot. Using a potato masher or hand mixer, start mashing the potatoes. Add your butter and gradually pour in the milk or cream, continuing to mix until you get a smooth, creamy mash. Taste and season with salt and pepper, remembering that these simple seasonings really bring out the best in the potatoes.
Step 3: Sauté the Cabbage
While the potatoes are cooking, heat the olive oil or butter in a large skillet over medium heat. Add the shredded cabbage and cook, stirring occasionally, for about 5 to 7 minutes until it softens and becomes tender but still has a slight bite. Adding salt and pepper here enhances the cabbage’s natural sweetness and balances the cabbage’s texture against the creamy potatoes wonderfully.
Step 4: Combine and Finish
Once the cabbage is ready, stir it right into your mashed potatoes along with the chopped green onions. Mix everything thoroughly so that every creamy bite has bits of tender cabbage and bursts of fresh onion flavor. Serve immediately with a pat of butter melting on top to bring everything to the next level of indulgence.
How to Serve Colcannon Irish Potato Recipe

Garnishes
For a classic finish, top your colcannon with a little extra pat of butter right before serving. This melts over the warm mash and adds a glossy, rich touch. If you want to take it a notch higher, a sprinkle of fresh chopped green onions or a few crispy bacon bits can add extra color and flavor contrast.
Side Dishes
Colcannon makes a perfect companion to braised meats like corned beef or Irish stew, soaking up every bit of savory sauce. It also pairs beautifully with grilled sausages or roasted chicken, making a hearty, comforting meal that feels lovingly earned on any day.
Creative Ways to Present
Try layering the colcannon in individual ramekins topped with a breadcrumb and cheese crust, then broil for a few minutes for a crispy, golden top. Alternatively, you can turn the leftover colcannon into savory potato cakes by forming patties and pan-frying them until crispy on both sides—delicious with a dollop of sour cream or mustard.
Make Ahead and Storage
Storing Leftovers
If you have any leftover colcannon, store it in an airtight container in the refrigerator for up to 3 days. Because it’s such a comforting dish, leftovers reheat nicely with a little added milk or butter to restore the creamy texture.
Freezing
You can freeze colcannon, but keep in mind the texture might change slightly due to the cabbage. For best results, portion it into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating gently on the stove or in the microwave.
Reheating
Reheat colcannon slowly on the stove over low heat or in the microwave with short intervals, stirring often. Add a splash of milk or a small knob of butter to bring back its creamy softness and prevent drying out.
FAQs
What type of potatoes should I use for Colcannon?
Russet potatoes are ideal for this recipe because their high starch content creates a fluffy and creamy mash perfect for colcannon.
Can I use other greens instead of cabbage?
Absolutely! Kale, collard greens, or even spinach can be used as substitutes, giving the dish a slightly different flavor profile but retaining that wonderful texture contrast.
Is Colcannon typically served as a main dish or a side?
Traditionally, colcannon is served as a side dish, especially with hearty meats, but it’s filling enough to enjoy on its own for a lighter meal.
Can I make this recipe dairy-free?
Yes, you can substitute the milk and butter for plant-based alternatives such as almond milk and vegan butter to make this dish dairy-free without sacrificing creaminess.
How do I keep my colcannon from becoming watery?
Be careful not to add too much milk all at once while mashing and make sure to drain the potatoes well after boiling to avoid excess water diluting the dish.
