A recipe inspired by Irish colcannon

I discovered this recipe recently on Instagram. I don’t remember whose video it was, but the promise that after trying it I wouldn’t want to eat any other mash kept resonating in my head. After all, leeks and potatoes are a match made in heaven. 

I didn’t have kale (as the video suggested), but I did have fresh Swiss chard left over from the last time I made my cannellini soup. So I got to work, and the result was this delicious mashed potato dish that I loved so much I decided to share it with you.

While researching, I discovered that in Ireland and some regions of Scotland, they prepare a mashed potato dish to which they add cabbage, butter, salt, and pepper, called colcannon. Some people also add onion, garlic, or heavy cream.

Although I haven’t tried the original colcannon, I can say that whoever came up with the idea of adding sautéed leeks in butter to this recipe is a genius! My personal touch is the Swiss chard, which adds color and freshness, and the pinch of white pepper, which I think works better than black pepper.

(And now you know that this will be the mash at my Thanksgiving dinner 2025).

Bon appétit!
