Irish Colcannon Soup with Potatoes and Cabbage

Introduction

Irish Colcannon Soup takes the beloved flavors of traditional colcannon and transforms them into a warm, creamy bowl of comfort. Inspired by the classic Irish dish of mashed potatoes blended with cabbage or kale, this soup version keeps all the hearty richness while adding a smooth, spoonable texture that feels cozy and satisfying.

Tender potatoes simmer with gently softened cabbage, onions, and garlic, then blend into a velvety base enriched with butter and cream. The result is a rustic yet creamy soup that captures the heart of Irish home cooking.

Irish Colcannon Soup is perfect for chilly evenings, St. Patrick’s Day gatherings, or anytime you crave something warm, nourishing, and deeply comforting.

Ingredients Overview

Yukon Gold potatoes are ideal for this soup because of their naturally creamy texture. Russet potatoes also work well and create a slightly lighter finish.

Green cabbage is the traditional choice, bringing subtle sweetness and soft texture once cooked. Kale can be substituted for a deeper, earthier flavor.

Onion builds the savory base of the soup. Finely chopped onion softens and blends seamlessly.

Garlic enhances the flavor profile and complements the buttery potatoes.

Unsalted butter adds richness and classic colcannon flavor.

Chicken broth provides depth and body. Vegetable broth can be used for a vegetarian version.

Whole milk or light cream creates a smooth, velvety texture.

Salt and black pepper balance the dish.

Green onions or scallions are stirred in at the end for freshness.

Optional toppings include crispy bacon bits, shredded cheddar, or a drizzle of melted butter.
