Ingredients

• 2 lbs Russet or Yukon Gold potatoes, peeled and cut into 1-inch chunks (Russets give a fluffier mash, while Yukon Golds offer a creamier texture. Both work wonderfully!)
• 1/2 head green cabbage (about 4 cups shredded), or 1 bunch kale (about 4 cups chopped), tough stems removed
• 4 tablespoons unsalted butter, plus more for serving
• 1 cup milk or heavy cream, warmed (whole milk is preferred for richness)
• 1/2 cup chopped scallions (green onions), white and green parts separated
• 1 teaspoon salt, or to taste
• 1/2 teaspoon black pepper, or to taste

Directions

1. Boil & Steam-Dry Potatoes: Place the peeled and chunked potatoes in a large pot and cover with cold, salted water by about an inch. Bring to a boil over high heat, then reduce to a simmer and cook until fork-tender, about 15-20 minutes. Drain the potatoes thoroughly in a colander. Return the drained potatoes to the empty hot pot over low heat for 1-2 minutes, shaking occasionally, to steam-dry them. This crucial step removes excess moisture, preventing a gummy mash and ensuring a light, fluffy texture.
2. Sauté Greens & Scallions Properly: While the potatoes are cooking, melt 2 tablespoons of butter in a large skillet or Dutch oven over medium heat. Add the white parts of the chopped scallions and cook until softened, about 2-3 minutes. Add the shredded cabbage (or kale) to the skillet. Sauté, stirring frequently, until the greens are tender and slightly wilted but still have a bit of bite, about 5-7 minutes for cabbage or 3-5 minutes for kale. If the greens release too much water, increase the heat slightly to evaporate it, ensuring they don't become soggy. Season lightly with a pinch of salt and pepper.
3. Mash with Technique Cues: Remove the pot of steam-dried potatoes from the heat. Add the remaining 2 tablespoons of butter and the warm milk or cream. Using a potato masher, mash the potatoes until smooth and creamy. Be careful not to over-mash, as this can activate starch and lead to a gummy texture. If you prefer a smoother mash, you can use a potato ricer.
4. Fold & Serve with Butter Well: Gently fold the sautéed greens and the green parts of the scallions into the mashed potatoes until just combined. Taste and adjust seasoning with salt and pepper as needed. Transfer the Colcannon to a serving bowl. To create the traditional "butter well," make a small indentation in the center of the Colcannon and fill it with an extra pat of butter, which will melt into a luscious pool. Serve immediately.
