Corned Beef Potato Salad is the perfect choice when you want something hearty and satisfying that feels nostalgic and a little celebratory. For our family, this dish always reminds us of St Patricks Day gatherings when a can of corned beef could easily be transformed into something special with a few staple ingredients. It is quick to prepare and makes an impressive addition to any dinner table with its creamy balance of tangy and savory.
I whipped this up on a busy weeknight when I had just a can of corned beef and some cabbage on hand Now my kids ask for it on every family game night
Ingredients
- Potatoes: Choose medium waxy potatoes which hold their shape and soak up flavor perfectly after boiling
- Mayonnaise or salad dressing: Brings everything together for a creamy base For best taste pick a high quality real mayonnaise
- Milk: Loosens the dressing to help it blend through the salad
- Prepared mustard: Offers a peppery tangy bite I always reach for a sharp yellow mustard
- Vinegar: Adds brightness and helps cut through the richness of the corned beef Apple cider vinegar or white vinegar both work well
- Sugar: A little bit balances the acidity and gives the dressing a subtle sweetness
- Salt: Essential for depth and to lift every other flavor
- Finely shredded cabbage: Gives a crisp crunch and another layer of flavor Choose fresh green cabbage and shred just before mixing
- Chilled canned corned beef: Cubed cold so it holds together and mixes evenly Pick a good quality can with decent chunks
Step-by-Step Instructions
- Boil the Potatoes:
- Cook potatoes in gently simmering salted water for about 15 minutes until fork tender Drain and let cool completely before peeling and cutting into bite sized cubes The cooling time keeps the cubes from crumbling
- Make the Dressing:
- Whisk mayonnaise milk mustard vinegar sugar and salt in a medium bowl until the mixture is smooth and cohesive Taste and adjust seasoning if needed with a pinch more salt or an extra splash of vinegar
- Combine Salad Ingredients:
- In a large mixing bowl add the cooled potato cubes finely shredded cabbage and cubed chilled corned beef Pour the prepared dressing overtop Use a large spoon or spatula to gently toss everything together making sure each ingredient is coated but the potatoes remain intact
- Chill and Finish:
- Cover the bowl with plastic wrap and refrigerate at least 30 minutes The chilling step is important as it allows the flavors to meld Right before serving sprinkle with chopped parsley or chives if you like

I love the soft buttery potatoes in this dish most of all their texture makes every bite comforting and soaks up the tangy creamy dressing My grandmother would always insist on chilling the salad extra long so the flavors truly came together and it is a tradition worth keeping
Storage tips
Store leftovers in an airtight container in the refrigerator for up to three days The flavor develops even more as it sits but the salad is best eaten within this window to keep the textures fresh Avoid freezing as the potatoes and cabbage can become watery and lose their bite after thawing
Ingredient substitutions
If you do not have canned corned beef leftover roast beef also works well Swap mayonnaise for Greek yogurt for a lighter twist and try using purple cabbage or even coleslaw mix if you want extra color and crunch

Serving suggestions
Serve as a main or hearty side at picnics or potlucks and pair with soda bread or crusty rolls For a lighter meal enjoy it with a crisp green salad or roasted root vegetables
Cultural context
Corned beef and potatoes have deep roots in Irish cuisine though this salad is a delightful twist on traditional boiled dinners It blends resourcefulness and comfort perfect for celebrating holidays or simply making use of what you have on hand
