This single serving colcannon is a classic Irish potato and cabbage dish made with creamy mashed potatoes, butter, milk, and green onions, perfectly portioned for one.
Place the potatoes in a small pot and cover with cold water by about 1 inch. Add salt and bring to a boil. Cook for 15 to 20 minutes, or until the potatoes are fork-tender.
Pour the potatoes into a colander and let them drain well.
Return the empty pot to the stove over medium heat and melt 2 tablespoons of the butter.
Add the cabbage and cook for 3 to 4 minutes, stirring occasionally, until softened. Add the garlic and green onions and cook for 1 minute more.
Pour in the milk and stir. Add the drained potatoes back to the pot and reduce the heat to medium.
Mash the potatoes with a fork or potato masher until mostly smooth and well mixed with the cabbage. Season with salt to taste and serve warm, with butter on top if desired.
Notes
Cut Potatoes Evenly: Similar-sized pieces cook at the same rate and mash smoothly.
Choose the Right Potatoes: Russet or Yukon Gold potatoes produce the best texture for colcannon.
Salt the Cooking Water: Seasoning the potatoes as they boil builds flavor from the start.
Add Milk Gradually: Mash the potatoes first, then add warm milk a little at a time until the texture is just right.
