Colcannon (Irish Mashed Potatoes) Ingredients
For the Potatoes:
- 2 lbs Yukon Gold potatoes – Their creamy texture makes for the best mashed potatoes; you can substitute with Russet if needed
- 1/2 cup whole milk – Adds richness; cream can be used for an extra indulgent touch
- 4 tablespoons unsalted butter – Essential for flavor; substitute with olive oil for a dairy-free version
- 1/4 teaspoon salt – Enhances the natural flavors of the potatoes, adjust to taste
For the Greens:
- 1 cup green cabbage (shredded) – Traditional choice that adds a sweet crunch; kale or spinach can work as substitutes
- 3 green onions (sliced) – Adds a mild onion flavor; regular onions can be used, but use less due to stronger taste
For Serving:
- 1 tablespoon fresh parsley (chopped) – Offers a pop of color and freshness; omit if you prefer a simpler dish
- 1/4 teaspoon black pepper – Gives a lovely warmth; adjust based on your spice preference
How to Make Colcannon (Irish Mashed Potatoes)
1. Boil potatoes: Start by peeling and cubing about 2 pounds of russet potatoes. Place them in a large pot, cover with water, and bring to a boil over medium-high heat. Cook until tender, about 15-20 minutes.
2. Drain and mash: Once the potatoes are fork-tender, drain the water and return them to the pot. Mash them using a potato masher until they’re creamy and smooth, with no lumps remaining.
3. Sauté greens: In a separate pan, melt 4 tablespoons of butter over medium heat. Add 1 cup of chopped scallions or green onions and cook until softened, about 3-4 minutes. The aroma will be delightful!
4. Combine ingredients: Stir the sautéed scallions into the mashed potatoes along with 1 cup of warm milk, salt, and pepper to taste. Mix everything together until well combined and creamy.
5. Serve hot: Transfer your delicious colcannon to a serving dish, making a small well in the center for extra butter if desired. Enjoy this traditional dish while it’s still warm!
Optional: Top with crispy bacon bits for added flavor!

Tips for the Best Colcannon (Irish Mashed Potatoes)
- Choose Good Potatoes: Use starchy potatoes like Russets for a creamy texture. Waxy potatoes can lead to a gluey consistency.
- Perfectly Cooked Veggies: Ensure your cabbage or kale is tender before mixing. Undercooked greens can add unwanted crunch to your colcannon.
- Season Gradually: Start with a little salt and taste as you go. Too much salt can overpower the comforting flavors of your colcannon.
- Creamy Add-Ins: For extra richness, add warm milk or cream gradually until you reach your desired consistency without making it soupy.
- Avoid Over-Mixing: Stir gently to combine ingredients; over-mixing can make the potatoes gummy instead of fluffy and light.
How to Store and Freeze Colcannon (Irish Mashed Potatoes)

- Fridge: Store leftover colcannon in an airtight container for up to 3 days. This keeps it fresh and prevents drying out, ensuring every bite is creamy and delicious.
- Freezer: For longer storage, freeze colcannon in a freezer-safe container or heavy-duty freezer bag for up to 2 months. Make sure to leave some space at the top for expansion.
- Reheating: Thaw frozen colcannon overnight in the fridge before reheating. Warm it gently on the stovetop or in the microwave, adding a splash of milk for creaminess.
- Room Temperature: Avoid leaving colcannon at room temperature for more than 2 hours to ensure food safety and maintain its delightful flavor.

Make Ahead Options
If you’re looking to simplify your mealtime, Colcannon (Irish Mashed Potatoes) is a fantastic dish for meal prep. You can make the mashed potatoes and prepare the sautéed greens separately up to 24 hours in advance. For best results, peel and chop the potatoes, then store them submerged in water in the fridge to prevent browning. The greens can be cooked and stored in an airtight container for up to three days. When you’re ready to serve, simply boil the potatoes until tender, drain, and mash with butter and cream before folding in the reheated greens. This way, you’ll enjoy the comforting flavors of Colcannon without the last-minute rush!
Colcannon (Irish Mashed Potatoes) Recipe FAQs
What type of potatoes are best for Colcannon?
For the creamiest Colcannon, I recommend using starchy potatoes like Russets or Yukon Golds. They mash beautifully and absorb the butter and cream, giving you that dreamy texture. Look for potatoes that are firm, with no blemishes or green spots.
How should I store leftover Colcannon?
Leftover Colcannon can be stored in an airtight container in the refrigerator for up to 3 days. To keep it fresh, ensure it’s completely cooled before sealing. When you’re ready to enjoy it again, simply reheat it on the stovetop or in the microwave, adding a splash of milk for extra creaminess.
Can I freeze Colcannon?
Absolutely! Freezing Colcannon is a great way to preserve its deliciousness. Place cooled portions in freezer-safe bags or containers and freeze for up to 2 months. To reheat, thaw overnight in the fridge and warm gently on the stove, stirring in a bit of cream or butter to restore its silky consistency.
What if my Colcannon turns out too watery?
If your Colcannon is too watery, don’t fret! This can happen if there’s excess moisture from the cabbage or if you’ve added too much liquid. Simply return it to the heat and simmer it uncovered for a few minutes while stirring. This will help evaporate some of the liquid and thicken your dish.
Is Colcannon suitable for vegans or those with dietary restrictions?
Traditional Colcannon includes butter and cream, making it unsuitable for vegans. However, you can easily adapt this recipe! Substitute vegan butter and plant-based milk (like almond or oat milk) to create a delicious vegan version that everyone will love. Just be sure to check your cabbage is free from animal-derived waxes!
Can I add other ingredients to my Colcannon?
Definitely! While the classic recipe features just potatoes, cabbage, and butter, feel free to get creative! Add sautéed leeks or scallions for extra flavor, or even mix in some cooked bacon bits for a savory twist. Just remember to balance any additional ingredients so they enhance rather than overpower the dish!
