Ingredients You’ll Need
This Colcannon recipe calls for straightforward, pantry-friendly ingredients, each thoughtfully chosen to build its creamy texture, depth of flavor, and gorgeous color. With simple prep and no fuss, these essentials come together to make something truly special.
- Yukon gold potatoes: Their naturally buttery flavor and creamy texture make them perfect for mashing without being gummy.
- Salt: Essential for seasoning the potatoes and kale to enhance every flavor note.
- Butter: Divided use adds richness, one portion for sautéing, the other for folding into potatoes for smoothness.
- Leeks: These mellow, sweet onions add depth and a subtle caramelized aroma after sautéing.
- Kale: Provides a beautiful pop of green, a slight bitterness, and a lovely tender bite when cooked just right.
- Vegetable or chicken stock (optional): Used to deglaze and keep the leeks tender without burning, adding another flavor layer.
- Milk: Adds creaminess and helps bind the potatoes into a luscious mash.
- White cheddar cheese: Sharp and melty, it introduces a savory tang that pairs beautifully with the greens.
- Pepper: Freshly ground for a little kick and aromatic lift.
How to Make Colcannon
Step 1: Prepare and Boil the Potatoes
Start by peeling and roughly chopping your Yukon gold potatoes into evenly sized pieces; this way, they cook evenly and mash to a perfect creamy consistency. Place them in salted water and bring to a boil, then simmer until tender, about 20 to 25 minutes, testing with a fork to ensure they’re soft and ready for mashing.
Step 2: Clean and Sauté the Leeks
While the potatoes boil, wash your leeks thoroughly to remove any grit hidden between the layers. Heat half your butter in a skillet with relatively high sides over medium heat, then add the chopped leeks. Slowly sauté them until soft and a little caramelized, about 20 to 25 minutes, deglazing frequently with a splash of vegetable or chicken stock to keep that lovely flavor from sticking or burning.
Step 3: Add the Kale to the Leeks
Once the leeks are tender and sweet, stir in the thinly sliced kale, seasoning lightly with salt. Continue cooking until the kale wilts and becomes tender too, about 5 to 7 minutes. This combo of kale and caramelized leek is what makes the Colcannon so deliciously vibrant and full of character.
Step 4: Mash the Potatoes and Combine
Drain your cooked potatoes thoroughly, then rice or mash them until smooth but still a bit textured. Stir in the remaining butter, shredded white cheddar, salt, pepper, and milk to create that classic creamy, cheesy base of the dish. Finally, fold in your flavorful leek and kale mixture, tasting and adjusting the seasoning until it sings.
How to Serve Colcannon

Garnishes
Colcannon shines when topped with a little extra pat of butter, melted gently over the top for an irresistible glossy finish. You can also sprinkle finely sliced green onions or a handful of freshly chopped parsley to brighten the presentation and add a hint of freshness that balances the richness.
Side Dishes
This dish pairs beautifully with traditional Irish mains like corned beef or shepherd’s pie, but it’s equally magnificent alongside roasted chicken, pan-seared trout, or grilled sausages. Its creamy texture and punchy greens add a perfect contrast to meats with crispy or caramelized edges.
Creative Ways to Present
Impress guests by serving Colcannon in individual ramekins or hollowed-out mini pumpkins for a festive touch. You can also shape it into patties and pan-fry them into crispy cakes for a delightful twist that’s perfect for brunch or appetizers.
Make Ahead and Storage
Storing Leftovers
Colcannon keeps very well in the refrigerator—place leftovers in an airtight container and consume within 3 to 4 days. The flavors tend to deepen as it rests, though the texture might firm up slightly, which is easy to remedy on reheating.
Freezing
You can freeze Colcannon, but because of the milk and butter it contains, it’s best to do so in portion-sized containers to maintain quality. Freeze for up to 2 months and avoid freezing if you want the freshest texture possible.
Reheating
Reheat gently on the stovetop over low heat, stirring often, and add a splash of milk or broth if it seems dry. Microwave works as well, but be careful to stir midway to rewarm evenly and avoid drying out any part of this creamy delight.
