Corned Beef Potato Salad is that rare kind of comfort food that feels both nostalgic and special enough for a celebration meal. I rely on this recipe every St. Patrick’s Day when family gathers around the table, but it is just as welcome on any chilly night when pure heartiness is what everyone craves. The simple ingredients transform a humble can of corned beef and a handful of pantry staples into a filling, creamy salad with just the right amount of crunch from cabbage and a bright lift from mustard.
My family asks for this every March and it always disappears faster than I expect. Making it brings back memories of helping my mom chop veggies while we waited for parade day to start. Its comforting flavors feel like a warm hug at the table.
Ingredients
- Mayonnaise: creates that luscious base dressing and binds everything together a good quality mayo will give the best creamy texture
- Prepared mustard: gives the salad its tangy backbone choose a sharp Dijon for more punch or yellow for mildness
- Shredded cabbage: adds a crucial fresh crunch look for tight heads that feel heavy for their size
- Canned corned beef: makes this hearty and substantial go for leaner brands with balanced saltiness
- Potatoes: build the foundation waxy types like Yukon Gold hold their shape well when boiled
- Whole milk: softens the dressing without thinning it too much fresh milk will work best
- Vinegar: adds a subtle brightness use mild apple cider or white vinegar for the right lift
- Sugar: rounds out the tang of the mustard and vinegar with a whisper of sweetness
- Salt: sharpens all flavors just a pinch brings everything together
- Fresh parsley or chives: for garnish will brighten finished salad choose vibrant green herbs for the freshest finish
Step-by-Step Instructions
- Boil and Cube the Potatoes:
- Simmer peeled potatoes in well salted water until fork tender but not falling apart. Drain thoroughly then let cool to room temperature before cutting into bite sized cubes. Cooling prevents them from getting mushy in the salad.
- Mix the Dressing:
- In a large bowl whisk together mayonnaise milk prepared mustard vinegar sugar and salt. Whisk until smooth and fully blended so the dressing is creamy with no lumps of sugar or mustard.
- Combine Cabbage Corned Beef and Potatoes:
- Add the cooled potato cubes finely shredded cabbage and bite sized cubes of chilled corned beef to a big mixing bowl. Fold gently to avoid breaking up the potatoes.
- Add Dressing and Toss:
- Pour the prepared dressing over the potato mixture. Toss gently but thoroughly so every piece of potato and cabbage is wrapped in creamy dressing and pink bits of corned beef are evenly distributed.
- Chill to Meld the Flavors:
- Cover the salad and refrigerate for at least half an hour. This step lets flavors mingle and makes the salad extra refreshing. Just before serving sprinkle with fresh chopped parsley or chives for color and brightness.

This salad always brings me back to St. Patrick’s Day tables crowded with laughter and stories about past holidays. My favorite ingredient is the tender potatoes which soak up every drop of tangy dressing and make the dish so much more than a side.
Storage Tips
Store Corned Beef Potato Salad in an airtight container in the fridge for up to three days. The flavor actually deepens as it sits. If needed stir in a spoonful of extra mayo before serving to restore the creamy texture.
Ingredient Substitutions
If you do not have canned corned beef use leftover roast beef or cooked ham for a different twist. Greek yogurt can swap for half the mayo to lighten up the dressing. Cauliflower florets work well for a low carb option.
