kcalIngredients
2 lbs Yukon Gold potatoes (peeled and chopped)
4 tbsp unsalted butter (plus extra for serving)
1 cup kale or cabbage (finely chopped)
3 scallions (sliced thin)
1/2 cup heavy cream or milk
Salt and pepper to taste
Optional: Crispy bacon bits (because everything’s better with bacon)
Step-by-Step Instructions
- Boil the potatoes: Cook in salted water for 15–20 minutes until fork-tender, then drain well.
- Sauté the greens: In 1 tbsp butter, cook kale/cabbage and scallions for 3–4 minutes until wilted. Set aside.
- Mash the potatoes: Return to pot with cream, remaining butter, salt, and pepper. Mash to desired texture.
- Fold in the greens: Gently mix sautéed greens into mashed potatoes. Adjust seasoning.
- Serve hot: Make a well in the center of each serving and fill with more butter.
Storage Instructions
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave or on the stove with a splash of milk to revive the creaminess. Freezing?
IMO, it’s not ideal—the texture gets weird. Just eat it all now.
Why You Should Make This

It’s also versatile—serve it as a side or main dish. Plus, it’s a conversation starter. “Oh, this? Just my ancestral Irish roots shining through.”

FAQs
Can I use regular potatoes instead of Yukon Gold?
Sure, but Yukon Golds are creamier and richer.
Russets work in a pinch, but you’ll need extra butter to compensate for their dryness.
Is colcannon gluten-free?
Yep! Just double-check your butter and cream labels if you’re ultra-sensitive.
Can I make this ahead of time?
Absolutely. Prep everything, then reheat with a little extra cream.
FYI, the greens might darken, but it’ll still taste amazing.
Why is my colcannon gummy?
You overworked the potatoes. Mash gently—don’t turn them into glue.
