Stick with the Irish theme with these satisfying Potato Farls!

With St. Patrick’s Day quickly approaching I wanted to share an authentic Irish recipe and not simply green-coloured stuff. It’s difficult to separate the Irish from potatoes, the vegetable so loved by the entire nation.
If I am honest, I can’t imagine not eating potatoes at least a couple of days a week. They are so versatile and I don’t need to sell you on the delicious factor!
Roasted, fried or mashed potatoes are potato recipes that will always reign supreme. If you want to take them up a notch, you can always bake them with cream in this delicious gratin recipe or layer them with caramelised onions and mushrooms in a cozy casserole.
But one of my favourite ways to enjoy spuds is to make Colcannon.

What is Colcannon?
Colcannon is a traditional Irish dish of mashed potatoes with milk, butter and most importantly an addition of cabbage or kale and green onions. Sometimes leeks, scallions or onions can be added as well, for more flavour.
For my recipe I decided to use Savoy cabbage for a couple of reasons. I absolutely love the crinkled texture of the Savoy cabbage leaves. I also find it to be more tender than white cabbage, which lends itself well to the creamy consistency of the mash.
Some colcannon recipes also feature garlic or bacon. Those are all great additions!

Recipe Tips and Notes
- For the best fluffy texture use the correct potatoes, which are labeled floury or starchy. Russet or Yukon Gold potatoes in the US or Maris Piper, King Edward, Vivaldi and Desiree in the UK.
- Peel and cut the potatoes in the similar-sized pieces, boil in salted water and drain in a This is an affiliate link.colander. The total time they take will depend on the size you cut them to, but make sure they are fork-tender.
- Let the cooked potatoes steam dry!! This step is important in ensuring your potatoes will turn into a fluffy mash and not a glue-like mess. A lovely creamy texture is everything when it comes to mashed potatoes!
- Mash with a This is an affiliate link.potato masher, then stir in butter and hot milk infused with green onions. Add in cooked Savoy cabbage last.
- Season the potato mixture well with salt and white or black pepper. Mashed potatoes that are under-salted are never exciting!
Serving suggestions
Colcannon is a side dish that can be used any time you would normally serve mashed potatoes. Which means there are a near infinite number of meals where this recipe will be a fantastic addition.
I especially love it with Roast Chicken or alongside our delicious Ham or Irish Beef Stew. And of course it is amazing with Steak and Ale Pie!
Storage and leftovers
Leftovers can be stored in an This is an affiliate link.airtight container for 3-4 days in a refrigerator and in a freezer for 2-3 months. They can be reheated in a microwave but will come out best when placed covered in an oven preheated to 180C/350F for 15-20 minutes, or until they are hot throughout.
