Buttery mashed potatoes with sautéed leeks and crispy kale for a comforting Irish side.

# Ingredient List:

→ Potatoes

01 - 2 lbs Yukon Gold or Russet potatoes, peeled and cut into chunks
02 - 4 tablespoons unsalted butter
03 - 1/2 cup whole milk
04 - 1/4 cup heavy cream
05 - Salt and freshly ground black pepper to taste

→ Vegetables

06 - 2 large leeks, white and light green parts only, thinly sliced and rinsed
07 - 3 spring onions, finely sliced
08 - 1 small bunch kale (about 5 oz), stems removed and leaves torn into bite-sized pieces
09 - 2 tablespoons olive oil

→ Garnish

10 - 2 tablespoons chopped fresh parsley, optional

# Steps:

01 - Preheat oven to 400°F. Toss kale leaves with olive oil and salt, spread on baking tray, and roast for 10-12 minutes, stirring halfway through, until crisp but not burnt. Set aside.
02 - Place potatoes in large pot and cover with salted cold water. Bring to boil, then reduce heat and simmer for 15-18 minutes until fork-tender. Drain thoroughly.
03 - While potatoes cook, melt half the butter in large skillet over medium heat. Add leeks and spring onions, sauté gently for 6-8 minutes until soft and fragrant but not browned.
04 - In small saucepan, heat milk and cream together over low heat until just warm.
05 - Mash drained potatoes with remaining butter. Gradually add warm milk and cream mixture while stirring until smooth and fluffy. Season with salt and pepper to taste.
06 - Fold sautéed leeks and spring onions into mashed potatoes. Taste and adjust seasoning as needed.
07 - Spoon mashed potatoes into serving bowl. Top generously with crispy kale and sprinkle with fresh parsley if desired.

# Expert Advice:

01 -
  • Classic Irish comfort food with a contemporary crispy kale twist.
  • Naturally gluten-free and vegetarian — perfect for a variety of dietary needs.
  • Ready in just 50 minutes with simple, accessible ingredients.
  • Incredibly creamy and fluffy thanks to warm milk, heavy cream, and plenty of butter.
  • Versatile side dish that pairs beautifully with roast chicken, sausages, or a fried egg on top.
02 -
  • Use a potato ricer instead of a masher for an ultra-smooth, lump-free result.
  • Always warm your dairy — adding cold milk or cream to hot potatoes can make them gluey.
  • Don't skip draining the leeks — rinsing and drying them well prevents excess moisture in the final dish.
  • Watch the kale closely in the oven; it can go from crispy to burnt very quickly in the last few minutes.
  • Season in layers — salt the cooking water, the leeks, and the finished mash separately for the best flavour.
