Ingredients
Base
- 2½ lbs (1.1 kg) floury potatoes (Russet or Yukon Gold), peeled and quartered
- ½ lb (225 g) curly kale or green cabbage, stems removed, finely shredded
- 1 cup (240 ml) whole milk or half-and-half
- ½ cup (113 g) Irish butter (Kerrygold preferred), divided
- 6 scallions (green onions), thinly sliced (white + green parts)
- 1½ tsp fine sea salt
- ½ tsp white or black pepper
For Serving
- Extra 2–4 tbsp melted Irish butter
- Chopped parsley or extra scallions
- Cracked black pepper
Essential Tools and Equipment
- Large pot
- Colander
- Potato masher or ricer
- Large skillet
- Wooden spoon
Step-by-step process
- Boil potatoes: Place peeled potatoes in cold salted water. Bring to a boil; cook 15–20 minutes until fork-tender—don’t overcook or watery mash.
- Prep kale/cabbage: While potatoes cook, blanch kale in boiling water 3–4 minutes until bright green and tender. Drain; squeeze dry—removes bitterness.
- Warm dairy: In the same skillet, melt 4 tbsp butter over medium-low heat. Add scallions; sauté 2 minutes until soft and fragrant. Pour in milk; heat until steaming—infuses flavor.
- Drain & dry potatoes: Drain potatoes well; return to hot pot over lowest heat 1 minute—steam evaporates for fluffy mash.
- Mash smooth: Add half the warm scallion-milk mixture + 4 tbsp butter + salt + pepper. Mash vigorously—lumps disappear.
- Fold greens: Add blanched kale and remaining scallion-milk. Fold gently—ribbons of green throughout. Taste; adjust salt and pepper—should be deeply savory.
- Create butter well: Pile colcannon in a warm serving bowl. Make a deep indent in the center; pour in 2–4 tbsp melted butter—traditional “lake.”
- Serve hot: Sprinkle parsley or extra scallions. Encourage dipping each spoonful into the butter pool.
Mistakes to avoid
- Watery greens: Squeeze kale dry—soggy colcannon fails.
- Cold milk: Lumpy mash—warm dairy essential.
- Overboiling potatoes: Gluey texture—fork-tender only.
- Skipping butter well: Loses soul—generous pool is non-negotiable.
- No salt in potato water: Bland base—salt the water like the sea.
Variations of the Best Traditional Colcannon
- Bacon & Leek: Fry 4 strips of bacon; sauté leeks in fat.
- Champ Version: Skip kale; double scallions.
- Garlic Lover: Roast 1 head of garlic; mash in.
- Vegan Glow: Olive oil + plant milk + nutritional yeast.
- Cheesy Twist: Fold in ½ cup Dubliner or sharp cheddar.
Tips for better storage
- Refrigerator: Airtight up to 4 days—flavor improves day 2.
- Freezer: Portion in bags up to 3 months. Thaw overnight; reheat with a splash of milk.
- Reheating: Low heat + extra milk/butter; stir often.
- Make-ahead: Prepare the day before; reheat gently on the stove.
- Revive richness: Fresh butter well before serving.
