Irish Champ Potatoes — Do This Next

Follow these steps to make perfect Irish Champ Potatoes every time:
Step 1: Prepare Your Potatoes
Peel 2 pounds of russet potatoes and cut them into large, evenly sized chunks. This ensures they cook uniformly and mash easily.
Step 2: Boil Until Tender
Place the potatoes in a large pot and cover with cold water. Add a pinch of salt and bring to a boil over medium-high heat. Let them cook for about 15-20 minutes, or until a fork slides through easily.
Step 3: Drain and Dry
Drain the potatoes well in a colander. Return them to the hot pot for a minute or two to evaporate excess moisture—this step helps keep the mash creamy, not watery.
Step 4: Mash the Potatoes
Use a potato masher or ricer to mash the potatoes until smooth and fluffy. Avoid over-mixing to prevent gluey texture.
Step 5: Add Butter and Cream
Stir in 4 tablespoons of butter and 4 tablespoons of heavy cream. Mix gently until fully combined and irresistibly creamy.
Step 6: Season
Season with 1 teaspoon of salt and 1/2 teaspoon of ground black pepper. Taste and adjust seasoning as needed.
Step 7: Mix in Green Onions
Fold in the 1/3 cup sliced green onions along with the remaining tablespoon of butter. The butter melts slightly, marrying the flavors beautifully.
Step 8: Serve Immediately
Irish Champ Potatoes are best enjoyed warm. Serve alongside your favorite main dish and enjoy!
Easy Ingredient Swaps

If you want to tailor this recipe or work with what you have, here are some simple swaps:
- Russet Potatoes: Yukon Gold potatoes can be used for a creamier, buttery texture.
- Heavy Cream: Substitute with whole milk or half-and-half for a lighter version.
- Butter: Use a plant-based butter alternative if you prefer dairy-free options.
- Green Onions: Chives or finely chopped leeks can provide a similar mild onion flavor.
Learn from These Mistakes
Irish Champ Potatoes are straightforward, but a few common pitfalls can affect the outcome. Here’s what to avoid:
- Overcooking the potatoes: This can make them waterlogged and mushy.
- Under-seasoning: Potatoes need ample salt to bring out their natural flavor.
- Using cold cream and butter: Adding cold dairy cools the potatoes and makes the butter clump.
- Over-mashing: Can cause the potatoes to become gummy instead of fluffy.
- Skipping the drying step: Leaving excess water in the potatoes results in watery mash.
Prep Ahead & Store
You can prepare Irish Champ Potatoes ahead of time, making them convenient for busy schedules. After mashing and seasoning, transfer the potatoes to an airtight container and refrigerate for up to 2 days. When ready to serve, gently reheat on the stovetop over low heat or in the microwave, stirring occasionally. Add a splash of cream or a pat of butter if the potatoes seem dry.
Common Qs About Irish Champ Potatoes
Can I make Irish Champ Potatoes vegan?
Yes! Replace the butter with a plant-based alternative and use unsweetened non-dairy milk or a vegan cream substitute to keep the dish creamy and delicious.
What’s the difference between Irish Champ and regular mashed potatoes?
Irish Champ specifically includes finely sliced green onions mixed into the creamy potatoes, giving it a fresh onion flavor that regular mashed potatoes don’t have.
How do I keep Irish Champ Potatoes warm without drying them out?
Cover the potatoes with a lid or foil and keep them in a warm oven (around 200°F) until ready to serve. Stir occasionally and add a splash of cream if needed to maintain moisture.
Can I freeze Irish Champ Potatoes?
While you can freeze mashed potatoes, the texture may change slightly upon thawing. For best results, freeze in airtight containers and thaw overnight in the refrigerator before reheating gently.
