Ingredients
For this traditional colcannon, you’ll work with two main groups. For the potato base — russet potatoes, salt, and milk or cream — use starchy russets for the fluffiest mash. For the greens and flavor — unsalted butter, kale or cabbage, and green onions — fresh is best, but any leafy green you love will work here.
| Amount | Ingredient |
|---|---|
| 4 medium (2–2½ lbs) | Russet potatoes, peeled and cut into 1½-inch pieces |
| To taste | Salt (plus 2 tbsp for boiling water) |
| 5–6 tablespoons | Unsalted butter, plus more for serving (yes, real butter — margarine just doesn’t cut it here) |
| 3 lightly packed cups | Kale, cabbage, chard, or other leafy green, chopped |
| 3 stalks | Green onions, minced (about ½ cup) |
| 1 cup | Milk or cream (whole milk or heavy cream both work beautifully) |
Tools You’ll Actually Use
- Large pot (for boiling potatoes)
- Colander (for draining)
- Potato masher or fork
- Wooden spoon or spatula
- Measuring cups and spoons
- Chef’s knife and cutting board
Step-by-Step Instructions for This Colcannon Recipe
Step 1: Boil the Potatoes
Place your peeled, 1½-inch russet potato pieces into a medium pot. Cover with cold water by at least an inch — cold water helps the potatoes cook evenly from the outside in.
Add 2 tablespoons of salt to the water and bring to a rolling boil over high heat. Boil for 15 to 20 minutes, or until the potatoes are completely fork-tender. Drain through a colander and set aside.
Step 2: Cook the Greens
Return the same pot to the stove over medium-high heat. Add the 5 to 6 tablespoons of unsalted butter and let it melt until it’s hot and just starting to foam.
Add your chopped greens — kale, cabbage, chard, or whatever you’re using — to the pot. Cook for 3 to 4 minutes, stirring occasionally, until the greens are wilted and have released some of their water.
Step 3: Add the Green Onions
Toss in your minced green onions and cook for 1 minute more, just until they soften slightly and smell absolutely amazing. Your kitchen should be smelling like a cozy Irish pub right about now.
Step 4: Mash It All Together
Pour in the 1 cup of milk or cream and stir to combine with the greens. Add the drained russet potatoes back to the pot and reduce the heat to medium.
Use a fork or potato masher to mash the potatoes, mixing them right into the buttery greens as you go. Mash until you reach your preferred texture — some lumps are totally welcome and very Irish. Taste and add salt as needed.
Step 5: Serve Hot
Spoon the colcannon into a warm serving bowl. Press a little well in the center and drop in an extra knob of butter. Watch it melt into a golden pool — that’s the traditional way to serve it, and it’s everything.
Claire’s Pro Tips for Irish Colcannon Recipe
Making a truly great classic colcannon potatoes dish comes down to a few small details. The good news? None of them are complicated — just a little intentional.
Here are the tips I’ve picked up after making this dish more times than I can count (including a few early batches that were a little too gluey — we don’t talk about those).
Use starchy potatoes. Russets are your best friend here. Waxy potatoes like red or new potatoes won’t give you that fluffy, cloud-like texture that makes colcannon so irresistible.
Don’t over-mash. Mashing too aggressively breaks down the potato starches and turns everything gummy. Mash just until smooth — a few small lumps are perfectly fine and actually very traditional.
Warm your milk or cream. Cold dairy added to hot potatoes can make the mash seize up and get heavy. Give your milk a quick 30-second warm in the microwave before adding it to the pot.
Salt the boiling water generously. This is where most of the potato’s flavor comes from. Don’t be shy — the water should taste pleasantly salty, like the sea.
Try different greens. Kale gives a slightly earthy bite, cabbage is milder and softer, and chard falls somewhere in between. The Kitchn’s trusted guide to Irish colcannon notes that the greens you choose really do change the personality of the dish — so don’t be afraid to experiment.
Quick Fixes for Colcannon Recipe
My colcannon is too thick and stiff.
This usually means not enough liquid. Warm up a splash of milk or cream and stir it in a little at a time until you reach the consistency you want. Go slowly — it’s easier to add than to fix a runny mash.
My colcannon turned out gluey or gummy.
You likely over-mashed. Unfortunately there’s no fix for this one after the fact, but next time use a lighter hand and stop mashing as soon as the big lumps are gone. A fork often gives you more control than an electric mixer.
The greens taste a little bitter.
Kale can be slightly bitter, especially if it was cooked too quickly. Try cooking it a full 4 minutes — slightly longer wilting mellows out the bitterness. Cabbage or chard will give you a milder result if bitterness is a concern.
The colcannon got cold too fast.
Mashed potato dishes lose heat quickly. Serve in a warmed bowl (just fill it with hot water for a minute, then dry it) and keep the pot on the lowest heat setting until you’re ready to plate.
Variations and Fun Twists
This cozy side dish is wonderfully flexible. Here are some fun ways to make it your own.
Bacon colcannon: Cook 3–4 strips of bacon until crispy, crumble them, and fold into the finished mash. It adds a smoky, savory depth that’s ridiculously good.
Cheesy colcannon: Stir in a handful of shredded sharp cheddar or Irish cheddar while the potatoes are still hot. It melts right in and turns the whole thing into something extra indulgent.
Vegan colcannon: Swap the butter for vegan butter and use oat milk or unsweetened almond milk. It won’t be quite the same richness, but it’s still cozy and delicious.
Leek and colcannon: Swap the green onions for one thinly sliced leek sautéed in butter. Leeks give a sweeter, more mellow onion flavor that pairs beautifully with kale.
Serving, Storage, and Reheating
Colcannon is best served immediately, piping hot, with that classic butter knob melting in the center. It pairs beautifully alongside corned beef, roasted chicken, grilled sausages, or a simple fried egg on top for a quick weeknight dinner.
If you actually have leftovers (I sincerely doubt it), store them in an airtight container in the refrigerator for up to 3 days. The colcannon will firm up as it cools, which is perfectly normal. You might also enjoy it as a side to a lighter soup like this Mediterranean lemon chicken soup — a dreamy combo of comforting and bright.
To reheat, add a small splash of milk to the container and warm it over medium-low heat on the stovetop, stirring gently, until heated through. You can also microwave it in 60-second intervals, stirring between each. Add a little extra butter on top and it’ll taste like it was just made.
No-Waste Kitchen Magic
Got a bit of colcannon left? Don’t toss it — here’s how to give it a second life.
Colcannon cakes: Shape cold leftover colcannon into small patties and pan-fry in butter over medium heat until golden and crispy on both sides. Serve with a fried egg for the best next-morning breakfast.
Soup thickener: Stir a spoonful or two of colcannon into a broth-based soup to add body and creaminess without cream.
Stuffed peppers or mushrooms: Use leftover colcannon as a filling for baked bell peppers or large portobello mushrooms. Top with cheese and broil until bubbly.
FAQs About Colcannon Recipe
Can I make colcannon ahead of time?
Yes! You can make colcannon up to a day in advance. Store it in an airtight container in the fridge. When ready to serve, reheat on the stovetop over low heat with a splash of warm milk and a pat of butter, stirring gently until creamy again.
What’s the best way to store colcannon?
Store leftover colcannon in an airtight container in the refrigerator for up to 3 days. For best results, press plastic wrap directly onto the surface before sealing — this prevents a skin from forming on top.
Can I freeze this colcannon recipe?
Freezing mashed potatoes can make them grainy and watery once thawed, so it’s not ideal. If you must freeze, add a bit of extra butter before reheating and mash again after thawing to bring back some creaminess.
What greens work best in traditional colcannon?
Kale and cabbage are the most traditional choices. Kale gives a slightly earthy, robust flavor, while cabbage is milder and softer. Chard, spring greens, and even collard greens all work beautifully too — use whatever you have on hand.
How do I know when colcannon is done?
Your colcannon is ready when the potatoes are fully mashed and smooth, the greens are well incorporated, and the whole mixture holds together with a creamy, fluffy texture. Taste for salt before serving — that final seasoning check makes all the difference.
