Here's What You Need to Make It
Potatoes: For mashed potatoes choose floury potatoes, which have the right amount of starch, rather than a waxy variety like new potatoes. My favourite is Yukon Gold, but russet potatoes or red potatoes will also work perfectly for this recipe.
Cabbage: Because of its dense leaves and sweetness, this recipe works best with regular green cabbage. If you want to try it with other cabbage varieties you may have to shorten or even eliminate the cooking time for the cabbage.
Leeks: Leeks are in the onion family, but have a milder, sweeter flavour which doesn't overpower potatoes and cabbage. Use only the white and light green parts of the leeks.
Milk: Buttermilk is traditional but you can use whole milk or a non-dairy alternative. (our favourite is oat milk). You can also make these Irish mashed potatoes a little richer by replacing ½ of the milk with cream.
Butter: If you have unsalted butter, use it. If you use salted butter, be sure to taste, and reduce the amount of added salt if necessary.
Scallions: (Or green onions). These are perfect for garnish while also adding an extra flavour element. Feel free to omit them, or use parsley or chives.
How To Make It

3. Add cooked potatoes, milk, and butter to the pan and mash.

Pro Tips For Delicious Results
Cut potatoes into evenly sized chunks before boiling them. Don't cut them too small or they can end up waterlogged. Quartering the potatoes works best.
Shred the cabbage quite finely so that it softens in about 5 minutes when cooked.
Don't overboil the potatoes. Cook just until they are easily pierced with a fork, then drain immediately in a colander.
After draining the potatoes, return them to the still-warm pot that they were cooked in. Put the pot on very low heat and allow the potatoes to dry out completely, shaking the pan a few times. You can skip this drying step, but it removes excess water, making for fluffier mashed potatoes.
Warm the milk and butter before adding them. The warmed milk and butter will be quickly absorbed by the potatoes without having to cook them further.
Colcannon potatoes are best if eaten right away. However, you can make the whole dish ahead, refrigerate, cover in foil and then reheat in a low oven.
Yes, all mashed potatoes are usually gluten-free.
You can make this a vegan and dairy-free recipe. Replace the milk with a non-dairy milk (oat milk works especially well). Replace the butter with extra-virgin olive oil.
A simple potato masher works great for mashing, and you can also use a ricer or a food mill. Don't use an electric mixer as this can cause gluey potatoes.
Leftovers are a bonus! Shape leftovers into patties and fry them, or mix them with salmon and make Salmon Cakes
