Irish Colcannon Mashed Potatoes

There is something deeply comforting about a bowl of colcannon — Ireland's beloved mashed potato dish that has warmed families for centuries. This Irish-Inspired Colcannon Mashed Potatoes with Crispy Kale takes that timeless tradition and gives it a modern, vibrant twist. Creamy Yukon Gold potatoes are whipped with butter, warm milk, and heavy cream until impossibly fluffy, then folded with gently sautéed leeks and spring onions for layers of subtle, sweet flavour. The crowning glory? A generous handful of oven-roasted crispy kale that adds a satisfying crunch and a pop of earthy green. Whether you are serving it alongside a Sunday roast or enjoying it as a humble weeknight side, this dish is pure, soul-nourishing comfort food at its finest.

Colcannon has long been a staple of the Irish kitchen, traditionally made with kale or cabbage stirred straight into the mash. Here, we roast the kale separately to transform it into irresistible golden crisps that hold their texture on top of the bowl rather than melting into the potatoes. The leeks and spring onions are sautéed low and slow until meltingly soft, imparting a gentle sweetness that balances the richness of the butter and cream. Every spoonful carries that perfect combination of velvety smoothness and satisfying crunch — a dish that honours its roots while feeling entirely fresh and of the moment.

Ingredients

• Potatoes
  • 900 g (2 lbs) Yukon Gold or Russet potatoes, peeled and cut into chunks
  • 60 g (4 tbsp) unsalted butter
  • 120 ml (½ cup) whole milk
  • 60 ml (¼ cup) heavy cream
  • Salt and freshly ground black pepper, to taste
• Vegetables
  • 2 large leeks, white and light green parts only, thinly sliced and rinsed
  • 3 spring onions, finely sliced
  • 1 small bunch kale (about 150 g/5 oz), stems removed and leaves torn into bite-sized pieces
  • 2 tbsp olive oil
• Optional
  • 2 tbsp chopped fresh parsley, for garnish

Instructions

Step 1 — Preheat the oven

Preheat the oven to 200°C (400°F).

Step 2 — Roast the kale

Toss the kale leaves with olive oil and a pinch of salt. Spread on a baking tray and roast for 10–12 minutes, stirring halfway, until crisp but not burnt. Set aside.

Step 3 — Cook the potatoes

Place the potatoes in a large pot and cover with salted cold water. Bring to a boil, then reduce heat and simmer for 15–18 minutes, until fork-tender. Drain well.

Step 4 — Sauté the leeks and spring onions

While the potatoes cook, melt half the butter in a large skillet over medium heat. Add leeks and spring onions. Sauté gently for 6–8 minutes until soft and fragrant but not browned.

Step 5 — Warm the dairy

In a small saucepan, heat the milk and cream together until just warm.

Step 6 — Mash the potatoes

Mash the drained potatoes with the remaining butter. Gradually add the warm milk and cream mixture until smooth and fluffy. Season with salt and pepper.

Step 7 — Fold in the vegetables

Fold in the sautéed leeks and spring onions. Taste and adjust seasoning if needed.

Step 8 — Serve

Spoon the mashed potatoes into a serving bowl. Top generously with crispy kale and sprinkle with fresh parsley if desired.

Zusatztipps für die Zubereitung

Für besonders cremige Kartoffeln empfiehlt es sich, die abgetropften Kartoffeln kurz bei schwacher Hitze im Topf zu trocknen, bevor man sie stampft — so verdampft überschüssige Feuchtigkeit und das Ergebnis wird noch fluffiger. Achte darauf, die Milch und die Sahne wirklich warm (nicht kalt) einzuarbeiten, da kalte Milch das Püree zäh machen kann. Der Grünkohl sollte auf einem einzigen Backblech verteilt sein, damit er gleichmäßig röstet und nicht dampfgart — Überfüllung des Blechs ist der häufigste Fehler bei der Zubereitung von knusprigem Kohl.

Varianten und Anpassungen

Für eine vegane Version lässt sich das Rezept problemlos anpassen: Einfach pflanzliche Butter sowie pflanzliche Milch und Sahne verwenden. Wer einen rauchigen Geschmack bevorzugt, kann gekochten Speck oder Pancetta unter das fertige Püree heben. Für eine noch intensivere Zwiebelnote können die Frühlingszwiebeln durch Schnittlauch ersetzt oder ergänzt werden. Das Gericht eignet sich auch hervorragend als Hauptmahlzeit, wenn es mit einem Spiegelei oder pochiertem Ei serviert wird.

Serviervorschläge

Dieses irisch inspirierte Colcannon-Kartoffelpüree passt hervorragend als Beilage zu Brathuhn, Bratwürsten oder Lammkoteletts. Als vollständige vegetarische Mahlzeit genossen, empfiehlt sich ein Spiegelei oder pochiertes Ei obenauf. Ein frischer grüner Salat mit einem leichten Zitronen-Dressing rundet das Gericht harmonisch ab. Reste lassen sich am nächsten Tag in einer heißen Pfanne mit etwas Butter zu goldbraunen Bratplätzchen (Bubble and Squeak) aufbraten.
