Step‑by‑Step Instructions for Colcannon Soup

Step 1: Sauté Aromatics
In a large pot, melt 2 tablespoons of unsalted butter over medium heat. Add 1 diced onion and sauté for about 5 minutes until the onion is softened and translucent. Stir in 2 minced garlic cloves and cook for an additional minute, until fragrant, filling your kitchen with a delightful aroma.

Step 2: Cook Cabbage
Add 4 cups of chopped green cabbage to the pot, stirring it into the sautéed aromatics. Sauté the cabbage for 5-7 minutes until it wilts and begins to soften, slightly shrinking in volume. This step enhances its sweetness, setting a rich foundation for your comforting Colcannon Soup.

Step 3: Simmer Potatoes
Introduce 4 peeled and diced russet potatoes, followed by 4 cups of vegetable broth, 1 teaspoon of salt, and ½ teaspoon of black pepper. Bring the mixture to a boil, then reduce the heat to low and let it simmer uncovered for about 20 minutes. The potatoes should become tender enough to easily pierce with a fork.

Step 4: Blend for Texture
Using an immersion blender, carefully blend the soup directly in the pot until it reaches a thick, creamy consistency, but avoid over-blending to retain some chunky potato pieces. The goal is a comforting texture that remains hearty, ensuring your Colcannon Soup is both rich and satisfying.

Step 5: Add Cream and Kale
Stir in 1 cup of half and half, returning the pot to a gentle simmer over low heat. After a couple of minutes, add 2 cups of chopped kale leaves, allowing them to wilt for about 2-3 minutes. This addition brings vibrant color and nutrition, balancing the creaminess of the soup beautifully.

Step 6: Serve and Garnish
Ladle the warm Colcannon Soup into bowls, topping each serving with sliced green onions for a fresh burst of flavor. Optionally, sprinkle with cooked bacon bits for a savory crunch. Serve hot alongside crusty bread, inviting everyone to savor this hearty, comforting dish.
