Ingredients
For the Pea Salad Base
- ½ sweet onion, finely chopped
- 2 (12 oz) bags frozen green peas, thawed and drained well
- 3 large hard-boiled eggs, peeled and diced
- 5 mini sweet peppers (or 1 medium red or yellow bell pepper), diced
- 1 ½ cups aged Irish cheddar cheese, shredded or cut into small cubes
For the Creamy Tangy Dressing
- ½ cup mayonnaise
- ¼ cup sweet pickle relish
- 2 tsp spicy brown mustard (or Dijon mustard)
- 1 tsp dried thyme
- 1 tsp fine sea salt (adjust to taste)
How to Make Dublin Pea Salad
Step 1: Soak the Onions
- Place the finely chopped sweet onion into a small bowl and cover with about ½ cup of cold water.
- Let the onions soak for 10 to 15 minutes while you prepare the rest of the ingredients. This simple step removes the harsh, lingering bite of raw onion while keeping its refreshing crunch.
- Drain the onions thoroughly before adding them to the salad.
Step 2: Assemble the Salad Ingredients
- In a large mixing bowl, combine the thawed green peas, diced hard-boiled eggs, diced sweet peppers, and aged Irish cheese.
- Add the drained sweet onions to the bowl and gently toss the ingredients together.
Step 3: Whisk the Dressing
- In a separate small bowl, whisk together the mayonnaise, sweet relish, spicy mustard, dried thyme, and salt until smooth and well combined.
Step 4: Toss and Chill
- Pour the dressing over the pea and cheese mixture.
- Gently fold and toss until every ingredient is evenly coated.
- Cover the bowl tightly and refrigerate for at least 30 minutes before serving to allow the creamy dressing and savory flavors to meld together.
Pro Tips & Recipe Variations
- Thaw and Drain Thoroughly: Excess water from thawed peas can water down your dressing. Spread the thawed peas on a clean paper towel and pat them dry before mixing.
- Cube vs. Shred the Cheese: While shredded cheese blends smoothly into the salad, dicing the Irish cheddar into small, pea-sized cubes provides a delightful textural contrast in every bite.
- Add Smoky Bacon (Optional): For an extra layer of savory flavor, fold in ½ cup of crispy, crumbled bacon just before serving so it retains its crunch.
- Lighten Up the Dressing: If you prefer a lighter dressing, swap half of the mayonnaise for plain Greek yogurt or sour cream.
What to Serve With Pea Salad
This refreshing side dish cuts through rich, savory main courses beautifully. Pair it with:
- Grilled Meats: Barbecued chicken, grilled ribeye steaks, or pork chops.
- Holiday Mains: Baked ham, roasted turkey, or cornish game hens.
- Picnic Favorites: Sandwiches, burgers, bratwursts, or pulled pork sliders.
Storage Instructions
- In the Refrigerator: Store leftover salad in an airtight container in the fridge for up to 3 to 4 days. Give it a gentle stir before serving, as the dressing may settle at the bottom.
- Freezing: Do not freeze this salad. The mayonnaise dressing will separate, and the eggs and peppers will lose their crisp, pleasant texture upon thawing.

Frequently Asked Questions
Can I use canned peas instead of frozen peas?
Frozen peas that have been thawed are strongly recommended. They stay firm, sweet, and bright green, whereas canned peas are often too soft and can turn mushy when tossed with the dressing and eggs.
What kind of Irish cheese works best?
An aged Irish cheddar (such as Kerrygold Dubliner or a mature Irish cheddar) is ideal. It offers a slightly sweet, nutty, and sharp flavor that stands up well to the creamy dressing and sweet relish.
Can I make Dublin Pea Salad the night before?
Yes! Like most mayonnaise-based side salads, it tastes even better after chilling overnight. If making it more than 12 hours in advance, consider holding back a spoonful of mayonnaise to stir in right before serving to restore its fresh, creamy consistency.
