Ingredients

If you have any ingredients leftover from this Irish mashed potatoes recipe, check out our Leftover Ingredients Recipe Finder.
- Potatoes: 2 russet potatoes (about 1 lb). Peel and chop into large chunks so they cook evenly. Russets create creamy, fluffy mashed potatoes. Extra potatoes? Try them in a twice baked potato or hash browns for one.
- Butter: Salted butter adds rich flavor but unsalted butter works just as well; adjust the salt to taste.
- Cabbage: About 4 oz chopped green cabbage (about 1 cup). This tender cabbage mixed into the mash gives traditional texture and flavor. Kale can be used instead. Leftover cabbage? Use it in buffalo cauliflower tacos or a single serving of coleslaw.
- Green Onion & Garlic: 1 green onion and 1 clove garlic. These bring mild onion flavor that complements the creamy mash.
- Milk: Use 2% milk for a balance of creaminess and lightness. Heavy cream or half-and-half can be used for richer mashed potatoes.
- Salt: Essential for seasoning.
Recipe Variations
These simple variations let you customize this single serving colcannon to your taste:
- Colcannon with Bacon: Cook the cabbage and green onions in bacon drippings, then finish with crumbled cooked bacon for classic Irish flavor.
- Cheesy Colcannon: Stir in shredded cheddar or another melting cheese while mashing for a creamier version.
- Herb-Forward: Add fresh parsley or thyme for a light, fresh finish that complements the potatoes.
- With a Little Heat: Mix in a pinch of red pepper flakes or a small splash of hot sauce for gentle warmth.
- Root Vegetable Addition: Replace part of the potatoes with carrots, parsnips, or turnips for added texture and flavor.
How To Make Colcannon
These step-by-step instructions show how to make a single serving of classic Irish colcannon. Find exact ingredient amounts and full details in the recipe card below.
- Boil the Potatoes: Place the potatoes in a small pot and cover with cold water by about 1 inch. Add salt and bring to a boil. Cook for 15 to 20 minutes, or until the potatoes are fork-tender.
- Drain: Pour the potatoes into a colander and let them drain well.
- Melt the Butter: Return the empty pot to the stove over medium heat and melt the butter.
- Cook the Cabbage: Add the cabbage and cook for 3 to 4 minutes, stirring occasionally, until softened. Add the garlic and green onions and cook for 1 minute more.
- Add Milk and Potatoes: Pour in the milk and stir. Add the drained potatoes back to the pot and reduce the heat to medium.
- Mash and Season: Mash the potatoes with a fork or potato masher until mostly smooth and well mixed with the cabbage. Season with salt to taste and serve warm, with butter on top if desired.

Expert Tips
- Cut Potatoes Evenly: Similar-sized pieces cook at the same rate and mash smoothly.
- Choose the Right Potatoes: Russet or Yukon Gold potatoes produce the best texture for colcannon.
- Salt the Cooking Water: Seasoning the potatoes as they boil builds flavor from the start.
- Add Milk Gradually: Mash the potatoes first, then add warm milk a little at a time until the texture is just right.

Made these twice so far and they keep getting better. Recipe is perfect. Thank you again for all you share in the community!!
Iโm so glad youโre enjoying the recipe, that makes me so happy to hear!
Just to clarify before I make it. A pound of potatoes for one serving? Seems like an awful lot!
Yes, thatโs correct. We use 2 medium russet potatoes, which is about 1 pound. Once theyโre peeled, cooked, and mashed with the other ingredients, the volume reduces quite a bit and it makes one generous serving.
