- 3-4 cups kale: Fresh kale contributes a lovely texture and a burst of vibrant color.
- ¼ cup green onions: Provides a mild, oniony bite that complements the greens perfectly.

How to Make Colcannon Potatoes Recipe
Step 1: Cook the Potatoes
Start by adding the peeled and chunked russet potatoes to a large pot or a 5-6 quart Dutch oven. Cover them with water so they’re submerged by at least an inch and sprinkle in one teaspoon of salt. Bring the water to a boil, then let the potatoes cook for about 15 to 20 minutes until they become fork-tender. Once cooked, carefully drain the potatoes in a colander and set aside.
Step 2: Wilt the Greens
Use the same pot to melt the butter over medium heat. Toss in the chopped kale and cook for around 3 to 4 minutes, allowing the greens to soften and release their moisture. Add the green onions and minced garlic next, stirring them in for an extra minute to awaken those fresh, fragrant flavors that brighten up the dish.
Step 3: Add Milk and Season
Pour the cup of milk into the pot with the wilted greens and use a wooden spoon or spatula to scrape any bits stuck to the bottom; they’re full of flavor! Sprinkle in the remaining teaspoon of salt to balance the taste, and gently warm everything together so it melds into a lovely creamy base.
Step 4: Mash It All Together
Return the cooked potatoes to the pot with the buttered greens and milk. Using a potato masher or a large fork, mash everything together until the mixture becomes smooth and creamy with delicious flecks of kale and green onion woven throughout. Serve while warm for the best experience.

Make Ahead and Storage
Storing Leftovers
Store any leftover Colcannon potatoes in an airtight container in the refrigerator for up to 3 days. The flavors deepen overnight, making it a great dish to enjoy again with minimal effort.
Freezing
You can freeze Colcannon potatoes, but keep in mind that the texture of the kale might change slightly. Place the cooled mash in a freezer-safe container and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
To reheat, warm the mashed potatoes gently on the stovetop over low heat or in the microwave, stirring occasionally. Add a splash of milk or a knob of butter to restore creaminess if needed.

Can I prepare Colcannon potatoes ahead of time for a party?
Yes! You can prepare the dish a day before and store it in the refrigerator. Gently reheat just before serving, giving it a good stir and a splash of milk to refresh the creamy texture.
