Today we have a simple and super delicious Brown Butter Colcannon Recipe for St Patrick’s Day! We’re big potato lovers over here so this creamy mashed potato dish was a no brainer for us. We can’t stress how easy it is to make and it only requires a handful of ingredients.

We also love how this dish is able to sneak in some vegetables too, so it’s a win-win on both ends! If you’re not a fan of kale you can substitute spinach or even cabbage! You also don’t have to limit this to St Patricks Day, it makes an amazing side dish all year round! I often find myself serving this colcannon instead of regular mashed potatoes.

What is Colcannon?

Colcannon is a traditional Irish dish of creamy mashed potatoes stirred together with hearty greens, such as cabbage or kale. It’s a hearty and inexpensive dish that can be eaten year round.

Our version uses brown butter, because we think it makes everything better but especially potatoes! The nutty flavor really takes this dish over the top in the best way!

Variations

  • Use sweet potatoes instead of russet potatoes for a subtly sweet flavor!
  • Switch up with the greens with green cabbage, savoy cabbage, wilted spinach, collard greens, or Swiss chard in lieu of kale.
  • Add some sautéed leeks and/or sliced green onions (also called scallions) and/or spring onions to add even more flavor to the dish!
  • Stir some crispy crumbled bacon into the buttery potatoes!
  • Mix it up by adding herbs into the potatoes. Some of our favorites to add are chives and thyme!
  • Make the colcannon richer by stirring in a dollop of sour cream, a couple tablespoons softened cream cheese or even folding in some shredded white cheddar.

Making Ahead and Freezing Colcannon

Our brown butter colcannon can be stored in an airtight container, in the refrigerator for up to 3 days and frozen for up to 3 months. Just scoop colcannon into an airtight container and place in freezer for up to 3 months. When ready to reheat, slightly thaw, enough to scoop into a pot. Add 1/2 to 1 cup cream to pot and simmer on low, stirring as the colcannon melts, until mixture is smooth. Season with salt and pepper as needed and serve.
