Ingredient List

For the Potatoes

• 2 pounds (900 g) potatoes, peeled and chopped
• 4 tablespoons unsalted butter
• ½ cup whole milk (more if needed)
• Salt, to taste

For the Colcannon Mix

• 4 cups cabbage, finely chopped
• 2 leeks, white and light green parts only, sliced thin
• 2 tablespoons butter
• Salt and pepper, to taste
• Optional: chopped green onions for garnish

Ingredient Notes

• I always use Yukon Gold potatoes for this—it makes the mash extra creamy and buttery.
• Don’t skip the cabbage! It’s what gives colcannon its signature flavor and a subtle crunch.
• Leeks are key for that mild, oniony sweetness—white and light green parts only.
• Butter matters here—I love using European-style butter for richness.
• Milk should be warm when mixing with potatoes; it keeps the mash smooth and silky.

Kitchen Equipment Needed

• Large pot – For boiling the potatoes until tender. I love using my heavy-bottomed pot; it keeps the water from boiling over.
• Large skillet – To sauté the cabbage and leeks until soft and flavorful. A non-stick skillet works perfectly.
• Potato masher – Essential for smooth, creamy mashed potatoes. I always use a sturdy stainless-steel masher.
• Mixing bowl – To combine the potatoes with butter, milk, and the cabbage mixture. Any large bowl will do!
• Knife and cutting board – For chopping potatoes, cabbage, and leeks. I always keep a sharp chef’s knife—it makes prep so much easier.
• Measuring cups and spoons – To get your butter, milk, and seasonings just right.

Instructions

Step 1: Prepare the Potatoes

• Peel and chop the potatoes into evenly sized chunks, about 1–2 inches each. This helps them cook evenly.
• Place the potatoes in a large pot and cover with cold water. Add a pinch of salt.
• Bring to a boil over medium-high heat, then reduce to a simmer. Cook for 15–20 minutes, or until a fork slides easily through the potatoes.
  Pro Tip: Start with cold water—it ensures the potatoes cook evenly instead of the outside getting mushy while the inside is still firm.

Step 2: Sauté the Leeks and Cabbage

• While the potatoes are cooking, melt 2 tablespoons of butter in a large skillet over medium heat.
• Add the sliced leeks first, sauté for 2–3 minutes until slightly softened.
• Stir in the chopped cabbage and cook for 5–7 minutes until tender but still bright green.
• Season with a pinch of salt and pepper.
  Pro Tip: Don’t overcook the cabbage—you want a little texture to contrast the creamy potatoes.

Step 3: Mash the Potatoes

• Drain the cooked potatoes and return them to the pot.
• Add 4 tablespoons of butter and warm milk gradually, mashing until smooth and creamy.
• Season with salt to taste.
  Pro Tip: Use warm milk, not cold—it helps keep the mash silky and lump-free.

Step 4: Combine Everything

• Gently fold the sautéed cabbage and leeks into the mashed potatoes until evenly mixed.
• Taste and adjust seasoning with more salt and pepper if needed.

Step 5: Serve and Garnish

• Transfer the colcannon to a serving bowl.
• Optional: top with a small pat of butter and sprinkle with chopped green onions for a fresh pop of color.
• Serve hot alongside your favorite Irish dinner dishes.

Tips and Tricks for Success

• Cut the potatoes into even sizes so they cook at the same rate—no half-mashed chunks.
• Salt the water generously when boiling the potatoes; it’s the best way to build flavor from the start.
• Let the drained potatoes sit in the hot pot for 1–2 minutes before mashing to evaporate excess moisture.
• Add milk gradually while mashing so you don’t end up with overly loose potatoes.
• Taste after mixing in the cabbage and leeks—seasoning often needs a small boost at the end.
• Serve immediately for the creamiest texture, or keep warm covered over very low heat.

Ingredient Substitutions and Variations

• Potatoes: Russet potatoes work well if Yukon Golds aren’t available, though the texture will be slightly fluffier.
• Cabbage: Swap green cabbage for kale or savoy cabbage for a slightly different flavor and texture.
• Leeks: Use finely chopped onions or scallions if leeks aren’t on hand.
• Milk: Substitute with heavy cream for extra richness or use dairy-free milk for a lighter version.
• Butter: Try Irish butter or add a touch of garlic butter for deeper flavor.
• Add-ins: Mix in crispy bacon bits or shredded cheddar cheese for a modern twist on this classic dish.

Serving Suggestions

• I love serving this colcannon with corned beef or roasted ham—the creamy potatoes soak up all those savory juices beautifully.
• Pair it with grilled or roasted chicken for a comforting, well-balanced Irish dinner.
• Serve alongside sausages or bacon for a hearty meal that feels extra satisfying.
• I often enjoy it with buttered peas or steamed carrots on the side to add a pop of color and freshness.
• For a cozy meatless option, I’ll serve it with fried eggs on top—simple, filling, and so good.

Storage and Reheating Instructions

• Refrigerator: Store leftovers in an airtight container for up to 3–4 days.
• Freezer: Colcannon can be frozen for up to 2 months, though the texture may soften slightly when thawed.
• Stovetop reheating: Warm gently over low heat, stirring often and adding a splash of milk or butter if needed.
• Microwave reheating: Heat in short intervals, stirring between each round to keep it creamy and evenly warmed.

Yukon Gold potatoes are my favorite because they mash up creamy and flavorful, but Russet potatoes also work well if that’s what you have.
