Ingredients & Why They Work
To nail this Creamy Irish Champ Mashed Potatoes Recipe, the quality of your ingredients really shines through. Let’s talk about the key players you’ll want to have on hand for the best flavor and texture.

- Potatoes: Choose starchy or floury varieties—they give you that fluffy, melt-in-your-mouth texture that’s essential for Champ.
- Whole milk: Provides just the right creaminess and also acts as the perfect medium to soak up the onion flavor.
- Green onions (green parts only): Their gentle onion flavor is the soul of this dish, offering freshness without overpowering.
- Unsalted butter: Adds rich, creamy indulgence while letting you control the salt levels perfectly.
- Salt and white pepper: Simple seasoning to balance and elevate the subtle flavors without masking them.
Make It Your Way
The beauty of this Creamy Irish Champ Mashed Potatoes Recipe is how easy it is to tailor it to your taste buds and pantry. Whether you want to make it creamier, punch up the onion flavor, or try a subtle twist, it’s all about what makes you smile at the table.
- Variation: For a richer take, I love swapping the whole milk with half and half or light cream. It adds a velvety indulgence that feels extra comforting on chilly evenings.
- Green Onion Intensity: Experiment with the amount of green onions—sometimes I add just 4 for a gentle hint, other times I go all in with 8 for a vibrant onion punch that really wakes up the dish.
- Dairy-Free Option: Use a plant-based milk like oat milk and vegan butter to keep it creamy and lush without dairy. The key is warming the milk with the green onions to infuse flavor regardless.
- Herb Boost: Toss in a sprinkle of fresh parsley or chives as a garnish for a fresh herbal note that complements the buttery, oniony mash beautifully.
- Spicy Twist: If you enjoy a hint of heat, a light dusting of cayenne or smoked paprika sprinkled on top adds an exciting dimension without overpowering the classic flavors.
Step-by-Step: How I Make Creamy Irish Champ Mashed Potatoes Recipe

Step 1: Infuse Milk with Green Onion Goodness
Start by pouring ¼ cup (50 ml) of whole milk into a small saucepan and add the sliced green parts of 6-8 green onions. Warm this gently over low heat until it just begins to boil—keep a close eye so it doesn’t scorch. Then remove it from the heat and let the green onions steep for a few minutes. This infusion unlocks that subtle onion aroma and flavor that makes champ so special.
Step 2: Boil the Potatoes Until Tender
While your milk is infusing, peel 6 medium potatoes and cut them into even quarters. Place them in a large pot filled with salted water and bring it to a vigorous boil. Cook the potatoes until they’re very tender—about 15 minutes—so they mash smoothly without lumps. You can test them by poke-testing with a fork; they should slide off easily.
Step 3: Drain, Steam-Dry, and Prepare for Mashing
Drain your potatoes thoroughly in a colander. Return them to the hot pot and let them sit uncovered for 2-3 minutes. This steam-drying step helps evaporate extra water, keeping your mash creamy instead of watery. Meanwhile, strain the green onion-infused milk through a fine sieve to remove the onion pieces, reserving the flavorful milk for mashing.
Step 4: Mash, Add Butter and Finish with Seasoning
Begin mashing the potatoes until smooth using a potato masher or ricer. Gradually pour in the warm, infused milk and add ½ cup (100 g) of unsalted butter in chunks. Keep mashing and folding it all together until your mash becomes creamy and luscious. Finally, season with salt and white pepper to taste—white pepper keeps the delicate color and adds a gentle spice. Give everything a good stir to combine the flavors deeply.
Step 5: Serve Up and Garnish
Serve your Creamy Irish Champ Mashed Potatoes piping hot, topped with a pat of butter melting on top and a sprinkle of extra sliced green onions for that fresh, green crunch. This cozy side dish pairs wonderfully with meats, vegetables, or even as a standalone comfort plate. Enjoy every creamy, buttery bite!
Top Tip
Mastering the Creamy Irish Champ Mashed Potatoes Recipe is all about attention to detail—these tips will help you achieve the perfect fluffy, buttery texture every time.
- Infuse the Milk Properly: I’ve found that gently heating the whole milk with the sliced green onions just until it starts to boil, then letting it steep off the heat, really brings out that delicate onion flavor without overpowering the potatoes.
- Steam Dry Your Potatoes: After boiling and draining, letting the potatoes sit in the hot pot for a few minutes to steam dry removes excess moisture, which keeps your mash from becoming watery—a trick I learned after a few too-runny batches!
- Use Unsalted Butter: This gives you better control over the seasoning. Adding salt gradually ensures the final taste is perfectly balanced.
- Mash While Ingredients Are Hot: Mixing in the warm infused milk and butter while the potatoes are still hot makes the mash silky smooth—waiting too long can result in a clumpy texture that’s harder to fix.
