Colcannon Mashed Potatoes are, in my opinion, the king of mashed potatoes. They are the creamiest, silkiest mashed potatoes from scratch and are taken up a notch with little morsels of ham or bacon, sauteed cabbage, and generous bits of butter. These potatoes make a perfect dinner side dish!

Colcannon Mashed Potatoes
Growing up, my dad always preferred buying and making dehydrated mashed potatoes – the kind that came in a packet. They were so much easier to get smooth and were a lot less work compared to peeling, boiling and mashing real potatoes.
And while I’m definitely not anti-convenience (as some of those packet potatoes are actually not bad when it comes to ingredients), once you taste proper colcannon you’ll have a hard time going back to the more convenient options.
If you have a bit of extra time to make potatoes from scratch – this is the recipe you should spend your time on. It even reheats well which I cannot say for the dehydrated variety.
This is a great traditional Irish side dish that is hearty enough to serve as an indulgent lunch or afternoon snack and Saint Patrick’s Day is the perfect excuse to whip up a batch – although, once you taste it, you’ll be able to come up with any excuse to include it in your meal planning!
Even if you skip the cabbage, scallions, and ham (although, on the first batch you definitely should include them) this method of making potatoes shows why the Irish are rightfully known for them.

- 2 large scallions or 4 green onions
- Chopped parsley leaves for garnish
- Salt and pepper to taste
Instructions
- Chop up potatoes - you can peel if desired.

- Reheat the ham however you prefer - you can add it to the pan with the cabbage, boil it, or heat it in the microwave.
- When the potatoes are ready, drain and start mashing to remove all of the lumps, adding the butter in as needed to make mashing easier.
- Heat the milk (either on the stove or in the microwave) and add it to the potatoes.
- Season with salt and pepper and then stir in the cooked cabbage and ham, and sprinkle in the scallions.
- Serve with generous Tablespoons of butter and a sprinkle of fresh chopped parsley.

The recipes on this blog are tested with a conventional gas oven and gas stovetop. It's important to note that some ovens, especially as they age, can cook and bake inconsistently. Using an inexpensive oven thermometer can assure you that your oven is truly heating to the proper temperature. If you use a toaster oven or countertop oven, please keep in mind that they may not distribute heat the same as a conventional full sized oven and you may need to adjust your cooking/baking times. In the case of recipes made with a pressure cooker, air fryer, slow cooker, or other appliance, a link to the appliances we use is listed within each respective recipe. For baking recipes where measurements are given by weight, please note that results may not be the same if cups are used instead, and we can’t guarantee success with that method.
