Ingredients
- 3 large (about 2 lbs) Yukon Gold potatoes, peeled & quartered
- 2 teaspoons fine salt, plus more to taste
- 6 tablespoons unsalted butter, divided
- 3 cups coarsely chopped kale (or Savoy cabbage), ribs removed

How to Make Traditional Irish Colcannon
1️⃣ Boil the Potatoes
Place potatoes in a large pot. Cover with cold water by 2 inches. Add salt.
Bring to a boil and cook for about 12 minutes, until fork-tender.
Drain and set aside.
2️⃣ Sauté the Greens
In a skillet, melt 2 tablespoons butter over medium heat.
Add kale, white parts of green onions, and bay leaf.
Cook about 5 minutes, until tender.
Add milk and mustard powder. Let simmer gently. Reduce heat to low.
3️⃣ Mash the Potatoes
Return drained potatoes to the pot.
Add remaining 4 tablespoons butter and green onion tops.
Mash until nearly smooth.
4️⃣ Combine & Finish
Remove bay leaf. Stir the warm kale-milk mixture into the potatoes.
The mixture may look loose at first — it thickens beautifully.
Season with salt and black pepper.
Serve warm with an extra pat of butter melting on top. ☘️
