What is the difference between Colcannon and Colcannon Soup?

Colcannon is a traditional Irish dish made from mashed potatoes mixed with cabbage or kale. Colcannon Soup takes those same ingredients and transforms them into a creamy, savory soup. It maintains the comforting, earthy flavors of the original dish but offers them in a warm, spoonable format perfect for chilly weather.

Can I make Colcannon Soup ahead of time?

Absolutely. Colcannon Soup actually tastes better the next day as the flavors meld together. Simply let the soup cool completely before storing it in an airtight container in the refrigerator for up to 4 days. When reheating, add a splash of broth or milk to restore its creamy consistency.

Is Colcannon Soup vegetarian or vegan?

This recipe is vegetarian as it uses vegetable broth and contains no meat (though it’s often topped with optional bacon). To make it vegan , swap the butter for olive oil or vegan butter, use a plant-based milk instead of half and half, and skip the bacon garnish or use a vegan alternative.

Can I freeze Colcannon Soup?

Yes, Colcannon Soup freezes very well. Let it cool fully before transferring it to a freezer-safe bag or container. Lay flat to save space, and freeze for up to 3 months. To reheat, thaw overnight in the fridge, then warm gently on the stove, adding a little broth to loosen the texture if needed.

Instructions

In a large pot, melt butter over medium heat. Add diced onion and sauté until softened, about 5 minutes.
Stir in minced garlic and cook for 1 minute until fragrant.
Add chopped cabbage and cook until it wilts and softens, about 5–7 minutes.
Add peeled and chopped potatoes, vegetable broth, salt, and black pepper. Bring to a boil, then reduce heat and simmer for 20 minutes or until potatoes are tender.
Using an immersion blender, blend the soup to desired consistency, leaving some chunks for texture. Alternatively, use a food processor or blender in batches.
Stir in the half and half and bring back to a gentle simmer.
Add chopped kale and cook for 2–3 minutes until slightly wilted.
Serve hot, garnished with sliced green onions and chopped cooked bacon if using.

Notes

For a thinner soup, add extra broth or a splash of milk.
Soup thickens after storage—loosen with broth when reheating.
To make vegetarian, skip the bacon or use a plant-based alternative.
Use spinach or chard instead of kale if preferred.
Flavors deepen when made ahead—great for next-day meals.
