What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver a bold flavor and satisfying texture without the fuss. Each element plays a role in making the creamy colcannon mashed potatoes with cabbage and scallions a standout side.

• Potatoes: 2 pounds (900g) Yukon Gold or Russet potatoes, peeled and cut into chunks (Yukon Gold offers a naturally buttery texture)
• Cabbage: 3 cups (about 200g) green cabbage, finely shredded (adds a subtle sweetness and texture)
• Scallions: 4 large scallions, thinly sliced (for that fresh, slightly sharp bite)
• Butter: 4 tablespoons (60g) unsalted butter, divided (use a quality brand like Kerrygold for richness)
• Cream: ½ cup (120ml) heavy cream or half-and-half (choose based on your preferred richness)
• Milk: ¼ cup (60ml) whole milk, warmed (helps adjust mash consistency)
• Salt: 1 teaspoon kosher salt, plus more to taste (balances flavors)
• Black Pepper: Freshly ground, to taste
• Garlic: 1 clove, minced (optional, for a subtle savory note)

For those who want a dairy-free version, swap the butter for olive oil or a vegan butter substitute, and use coconut milk or any plant-based cream alternative. If you prefer a lighter mash, you can reduce the cream and add more milk. And during the winter months, this recipe pairs beautifully with roasted root vegetables or wilted kale from your pantry.

Equipment Needed

• Large pot for boiling potatoes
• Colander for draining
• Large skillet or sauté pan for cooking cabbage and scallions
• Potato masher or ricer (a ricer gives the smoothest texture, but a masher works just fine)
• Mixing bowl or the pot used for potatoes
• Wooden spoon or spatula for stirring
• Measuring cups and spoons

If you don’t have a potato ricer, don’t stress—I’ve used a simple masher countless times and it does the trick. Just avoid over-mixing to prevent gluey potatoes. A non-stick skillet is handy for sautéing the cabbage evenly, but a regular pan will work too. For budget-friendly options, the classic manual masher and any sturdy frying pan will do.

Preparation Method

1. Prep the Potatoes: Peel and cut 2 pounds (900g) of Yukon Gold or Russet potatoes into roughly 2-inch chunks. This helps them cook evenly. Place them in a large pot and cover with cold water by about an inch. Add 1 teaspoon kosher salt to the water to season the potatoes from the inside out.
2. Boil the Potatoes: Bring the water to a boil over high heat, then reduce to a simmer. Cook for 15-20 minutes or until the potatoes are fork-tender (they should easily break apart when poked). Drain thoroughly using a colander and set aside.
3. Cook the Cabbage and Scallions: While potatoes cook, melt 2 tablespoons of butter in a large skillet over medium heat. Add the minced garlic (if using), finely shredded cabbage (3 cups/200g), and sliced scallions (4 large). Season lightly with salt and pepper. Sauté for about 5-7 minutes until the cabbage softens and becomes slightly translucent but still retains a bit of bite. Remove from heat and set aside.
4. Mash the Potatoes: Return the drained potatoes to the warm pot or a mixing bowl. Mash with a potato masher or pass through a ricer for the smoothest texture. Gradually add the remaining 2 tablespoons of butter, ½ cup (120ml) heavy cream, and ¼ cup (60ml) warmed whole milk. Stir gently to combine. The mash should be creamy and smooth but not runny. Adjust milk quantity if needed.
5. Fold in the Vegetables: Gently fold the sautéed cabbage and scallions into the mashed potatoes, mixing just enough to evenly distribute without overworking the mash.
6. Season and Serve: Taste and adjust seasoning with salt and freshly ground black pepper. Serve warm as a perfect side that feels both traditional and fresh.

Pro tip: If the mash seems too stiff after resting a few minutes, you can stir in a splash more warm milk to loosen it up. Also, don’t rush the mashing step—too much mashing can make potatoes gluey, so be gentle.

Cooking Tips & Techniques

Getting mashed potatoes just right can be trickier than it looks, but here are some tips that have saved me from lumps and gluey disasters:

• Start potatoes in cold water: This ensures even cooking and prevents the outside from getting mushy before the inside is done.
• Use the right potatoes: Yukon Golds strike the perfect balance between fluffy and creamy. Russets are fluffier but can dry out if overcooked.
• Don’t over-mash: Mashing too vigorously breaks down the starch too much, making the mash gluey. I like to mash just until smooth but still a bit fluffy.
• Sauté cabbage gently: Overcooking cabbage can make it bitter and mushy; cook until just tender to retain some texture and sweetness.
• Warm your dairy: Adding cold cream or milk cools down the potatoes and makes the mash less creamy. Warm them slightly for the best texture.
• Multitask smartly: While potatoes boil, prep and sauté your cabbage and scallions to save time without rushing.

One time, I accidentally left the cabbage on too high heat, and it turned bitter and soggy. Lesson learned: medium heat and patience are key here. Also, if you love rich mashed potatoes, don’t skip the butter—it’s the soul of this recipe.

Variations & Adaptations

Colcannon mashed potatoes are endlessly adaptable, so feel free to make it your own:

• Vegetarian & Vegan: Use olive oil or vegan butter and substitute heavy cream with coconut cream or unsweetened almond milk for a dairy-free version.
• Seasonal Twist: Swap cabbage for kale or spinach in spring and summer for a brighter, greener mash.
• Cheesy Upgrade: Stir in shredded sharp cheddar or Parmesan for extra indulgence.
• Spiced Up: Add a pinch of nutmeg or smoked paprika to the mash for subtle warmth and depth.
• Garlic Lovers: Roast a whole head of garlic and mash it in for mellow, sweet garlic flavor.

One personal favorite variation is folding in caramelized onions along with the cabbage and scallions—adds a sweet, savory layer that’s hard to beat. For a playful twist, try pairing this creamy colcannon with a quick garlic butter shrimp pasta recipe that comes together in just 15 minutes for an easy weeknight feast.

Serving & Storage Suggestions

This creamy colcannon mashed potatoes dish shines best served warm and fresh, but it also holds up well for leftovers. I like to plate it as a hearty base alongside roasted meats or vegetable mains. A sprinkle of extra scallions or a pat of butter melts beautifully on top just before serving.

Pair it with crisp steamed green beans, roasted Brussels sprouts, or even the cozy crockpot honey garlic meatballs for a full meal that never feels boring.

To store, cool the mashed potatoes to room temperature and transfer to an airtight container. Refrigerate for up to 3 days or freeze for up to 2 months. When reheating, add a splash of milk or cream and gently warm on the stove or microwave, stirring occasionally for even warmth.

Flavors tend to deepen after a day, making leftovers even more enjoyable—just like many comfort dishes that improve with time.
