These classic Irish Mashed Potatoes are creamy and packed with flavor from the sautéed green cabbage. Perfect for celebrating St. Patrick’s Day or as a pairing with any meal!

As a lover of all types of potatoes, I can’t believe it’s taken me so long to try colcannon! It’s been on my list of recipes to make for years, but this year, in advance of St. Patrick’s Day, I finally made it happen!
Usually, I make mashed potatoes in bulk and freeze them for later, or freeze homemade hashbrowns. But having this new recipe for potatoes in my back pocket is so exciting!
Traditional Colcannon Recipe
Recently, I found a recipe for colcannon from 1830 that I used to form my ideas for this slightly modernized recipe. It’s very close to the original, with just a slight change that I’m not baking it in a form at the end!
The result is a super creamy mashed potatoes with pops of sautéed cabbage that pairs perfectly with roasted pork or beef! But no matter how you serve it, any potato lover is sure to enjoy this traditional rendition of Irish Colcannon.

This is a fun look at the historical recipe above. No measurements were provided, and very little instruction!

Ingredients
Simple ingredient recipes are what I love the most! This recipe calls for simple, whole ingredients that can even be grown or made at home! The full measurements and instructions can be printed at the end of the post.
- Potatoes – While many different types of potatoes can be used, even red potatoes, we opted for Russet potatoes, peeled.
- Greens – Cabbage, kale, and other greens can be used in this recipe, but we stuck with green cabbage.
- Butter – Used to sauté the cabbage and to make the mashed potatoes fluffy!
- Milk – Any type of milk will work in this recipe, even plant-based milks!
- Salt and Pepper – Just add to taste!
- Scallions or Green Onions – Topping to finish off the dish, optional but really delicious!
- Sour Cream – This is optional, but adds such a wonderful depth of flavor to the finished dish, that I highly recommend adding it!

Instructions
Ready in about 30 minutes, this recipe is so quick that you’ll want to serve it for every meal! My family has already requested it again, and even my fairly picky niece ate a large portion!
- Boil – Peel and roughly dice the potatoes. Boil a pot of water and add the potatoes to the pot. Boil them until they are soft.
- Sauté – Finely chop the cabbage. See the photo above for how finely I recommend chopping it. Add one tablespoon of butter to a large skillet and melt over medium-high heat. Once melted, add the cabbage to stir to coat. Sauté until the cabbage is soft and caramelized. Set aside until the potatoes are finished.
- Mash – Drain the soft potatoes and add to a large mixing bowl or bowl of an electric mixer with a paddle attachment. Add 1/2 a cup of butter to the bowl and mash well. Add 1/4 cup of milk to the mix and mash again until smooth and creamy.
- Mix – Add the cabbage to the bowl with the potatoes and mix well.
- Serve – Transfer to a serving dish, if desired. Top with chopped green onions and sour cream and serve right away.
