This colcannon recipe is the coziest side for any meal. Creamy Irish-style mashed potatoes are folded with buttery onions and tender kale.


Ingredients You’ll Need
- Potatoes: Starchy russet-style potatoes are the best because they mash well. Peel for smooth potatoes. You can also use leftover mashed potatoes.
- Dairy: Warm dairy blends more smoothly into the potatoes and helps keep them fluffy instead of gluey. You can substitute half and half or whole milk for a lighter option.
- Kale: No need to thaw the kale first, just cook it long enough to evaporate excess moisture so the mashed potatoes stay thick and creamy.
- Variations: Swap in sautéed cabbage for a traditional twist and add green onions or leeks for extra flavor. Finish with a pat of butter.



How to Make Colcannon
- Cook and drain potatoes (full recipe below).
- Sauté the onion in butter. Add kale and garlic powder and cook.
- Add potatoes and half the warmed cream to the pot. Mash potatoes.
- Stir in additional cream and fold in the kale onion mixture. Season before serving.

Holly’s Tips & Tricks
- For Smooth Potatoes: Drain the potatoes well. Mash potatoes right away while they’re hot.
- For Fluffy Potatoes: Warm the cream.
- For Perfectly Thick Potatoes: Cook the kale until it looks a bit drier and not watery.
- Add the Right Amount of Cream: Start with less, then finish with small splashes.
- For Extra Buttery Flavor: Melt a little butter and drizzle it over the top right before serving.
Leftovers That Stay Creamy
Keep leftovers in an airtight container in the refrigerator for up to 4 days and in the freezer for up to 2 months. Reheat in the microwave in short bursts, or low heat on the stove. Add a splash of cream or milk and stir often. Or cover with foil and warm in the oven until hot through. Add a pat of butter on top to refresh.

Colcannon Recipe
Equipment
Ingredients
- 2 pounds baking potatoes peeled & cut into 1-inch pieces
- ¼ cup butter more to taste
- 1 small onion diced
- 10 ounces frozen kale
- 1 teaspoon garlic powder
- ½ cup heavy whipping cream warmed
- salt and pepper to taste
Instructions
- Bring a large pot of salted water to a boil. Add the potatoes and simmer for 12 to 14 minutes or until tender. Drain well.
- While the potatoes are cooking, in a medium skillet, cook the onion in butter over medium heat for 3 to 4 minutes or until it begins to soften. Add the kale and garlic powder and cook for an additional 7 minutes or until tender.
- Add the drained potatoes back to the pot along with half of the warmed cream. Using a potato masher mash the potatoes adding additional cream as needed.
- Once smooth, fold in the kale and onion mixture. Season with salt and pepper.
Notes
- Choose to peel, or not to peel, the potatoes!
- Cut potatoes to similar sizes for even cooking.
- Cook kale enough to reduce the moisture in the dish, or run the risk of it becoming runny.
- Refrigerate leftovers covered for up to 4 days. Leftovers can also be added to other recipes.
- Reheat leftovers in the microwave, on the stovetop, or covered with foil in the oven until warmed through.
