Ingredients You’ll Need
You won’t believe how a handful of humble ingredients transform into such a favorite dish. Each element plays a special role in creating Traditional Irish Colcannon’s signature texture, flavor, and cozy appeal—so let’s break it down!
- Potatoes: Starchy varieties like Russets or Yukon Golds give a creamy, fluffy texture that’s just right for mashing.
- Unsalted Butter: Rich, sweet butter is the soul of classic colcannon, so don’t skimp! You’ll need it in both the mash and for sautéing.
- Whole Milk: Creamy whole milk (or substitute with cream for extra comfort) brings everything together for a dreamy mash.
- Green Cabbage: Thinly sliced cabbage cooks down into silky strands that add subtle earthy flavor and a pop of green.
- Green Onions: Their gentle bite and color make the dish lively and fresh, with just the right touch of scallion zing.
- Salt and Pepper: Don’t underestimate good seasoning—generously salt the water and season the final mash to taste.
- Optional Garnish: Extra pats of butter and a sprinkle of chopped parsley instantly dress up your Traditional Irish Colcannon for the table.
How to Make Traditional Irish Colcannon
Step 1: Prepare and Cook the Potatoes
Start by peeling your potatoes and chopping them into even chunks, ensuring they’ll cook uniformly. Place the pieces in a large pot, cover them with cold water, and add a generous pinch of salt. Bring everything to a roaring boil, then reduce the heat and let the potatoes simmer gently for 15 to 20 minutes, until they’re perfectly tender when pierced with a fork.
Step 2: Sauté the Cabbage and Green Onions
While the potatoes are doing their thing, grab a large skillet and melt half of your butter over medium heat. Toss in the sliced cabbage and let it cook, stirring now and then, for about 5 to 6 minutes, until it softens and turns beautifully glossy. Sprinkle in the green onions and give everything another 1 to 2 minutes—just enough for the onions to lose their edge but keep their brightness.
Step 3: Mash the Potatoes
Once the potatoes are fork-tender, drain them well and return them to the pot. Add the rest of the butter and the whole milk, then mash everything together until smooth and creamy. Whether you use a classic masher or a potato ricer, aim for a texture that’s luscious yet still hearty enough to stand up to the cabbage.
Step 4: Combine and Season
Stir the buttery cabbage and green onions into your mashed potatoes, folding it all gently so every bite gets a ribbon of veggie goodness. Taste and season generously with salt and pepper. The end result should be savory, rich, and shot through with cheerful colors—Traditional Irish Colcannon at its best!
Step 5: Serve and Enjoy
Scoop generous portions onto plates or into a large serving bowl, making a small well in the center of each mound. Add a pat of butter to each serving, letting it melt into golden pools. If you like, shower on some chopped parsley for that fresh and festive finish. Dig in while it’s piping hot!
How to Serve Traditional Irish Colcannon

Garnishes
The joy of serving Traditional Irish Colcannon is treating it like the showstopper it is. Add a pat of Irish butter on top of each serving for a glossy finish, and a sprinkle of fresh chopped parsley for a pop of color and herbal brightness. If you’re feeling extra decadent, try a quick grind of black pepper or a dusting of chive for even more depth.
Side Dishes
Colcannon is the perfect partner for so many Irish main courses. Pair it with slices of corned beef, juicy sausages, or slow-braised lamb stew for a meal that feels like a celebratory Sunday supper. You can also serve it alongside roasted root vegetables, grilled fish, or even fried eggs for a cozy breakfast-for-dinner twist.
Creative Ways to Present
Why not make your Traditional Irish Colcannon the star? For a fun twist, scoop it into individual ramekins or mini baking dishes, dot with cheese, and broil until bubbly and lightly browned. For entertaining, serve in a large, rustic bowl with a butter pool and scattered herbs—you’ll have guests lining up for seconds!
Make Ahead and Storage
Storing Leftovers
If you find yourself with extra Traditional Irish Colcannon (lucky you!), simply transfer it to an airtight container and pop it in the fridge. It will keep beautifully for up to three days, ready to reheat whenever you need a bit of cozy comfort in a hurry.
Freezing
For longer storage, you can freeze colcannon, though the texture might become slightly less creamy on thawing. Pack cooled portions into freezer-safe containers or heavy-duty zip bags, squeezing out as much air as possible. It will stay good for up to two months—just thaw overnight in the fridge before reheating.
Reheating
To bring your Traditional Irish Colcannon back to its luscious best, reheat gently on the stovetop over medium-low heat. Add a splash of milk or a knob of butter to revive its creaminess, and stir frequently so it heats through evenly. You can also use the microwave, pausing to stir so everything warms uniformly.
FAQs
Can I use different greens in colcannon?
Absolutely! While green cabbage keeps it classic, feel free to swap in curly kale or even Swiss chard for a slightly different twist. Each green offers its own flavor and texture, so experiment and see what you love best in your Traditional Irish Colcannon.
Is it possible to make colcannon vegan?
Yes, you sure can. Substitute your favorite plant-based milk for whole milk, and use a vegan butter. The result is still creamy, flavorful, and fully satisfying—so everyone at the table can dig in!
What’s the best potato variety for Traditional Irish Colcannon?
Starchy potatoes like Russets or Yukon Golds are ideal because they mash up fluffy and light, absorbing the butter and milk beautifully. If you prefer a slightly waxier texture, you can use red potatoes, but avoid very waxy types like fingerlings.
Can I make colcannon in advance for a party?
Definitely! Prepare your Traditional Irish Colcannon earlier in the day, then reheat gently just before serving. Stir in a little extra milk or butter as you warm it to restore its creamy texture.
Is Traditional Irish Colcannon gluten free?
Yes, the classic recipe is naturally gluten free, so it makes a crowd-pleasing side dish for gatherings where dietary restrictions are a concern. Just double-check that your butter and any add-ins are gluten free as well.
