Creamy Tuna Potato Salad with Peas and Eggs (Easy, Make-Ahead)
Lunch · Salads · Make-Ahead · Potluck-Friendly · Beginner-Friendly
📖 B. Introduction
This tuna potato salad is built from tender, buttery potato cubes folded with flaked tuna, bright green peas, and a lightly tangy mayonnaise-and-yogurt dressing, then crowned with halved hard-boiled eggs whose yolks stay just set and golden. It eats like a cross between classic American potato salad and the Spanish ensalada de patata con atún: creamy, but lifted by lemon, vinegar, and parsley so it never turns heavy.
What sets this version apart is how the potatoes are handled. They are cooked until just tender, then tossed with a splash of vinegar and olive oil while still warm, so they absorb seasoning from the inside instead of just wearing a coating of dressing. The peas thaw in the hot cooking water, which keeps them vivid and sweet rather than gray.
It works as a make-ahead lunch, a picnic or potluck dish, a light summer dinner with crusty bread, or a lunchbox filler that holds up well in the fridge. The salad is flexible, too: swap the tuna for canned salmon, lighten the dressing with more yogurt, or add olives and roasted peppers for a more Mediterranean feel.
⭐ C. Why You’ll Love This Recipe
- ✅ Mostly hands-off cooking: the potatoes and eggs cook at the same time in two pots, with about 20 minutes on the stove.
- ✅ Better flavor than most potato salads: dressing the potatoes while warm seasons them all the way through.
- ✅ Make-ahead friendly: it tastes better after a 1-hour chill and keeps well for up to 3 days in the fridge.
- ✅ Balanced and filling: potatoes, eggs, and tuna give carbohydrates and protein in one bowl.
- ✅ Lighter dressing: part Greek yogurt replaces some of the mayonnaise, adding tang without extra richness.
- ✅ Pantry-friendly: everything except the fresh herbs and eggs is a pantry or freezer staple.

This is a creamy, chunky salad: firm-tender potatoes, flaky tuna, and snappy peas in a tangy dressing with a soft but set egg on top. The single most important technique is cooking the potatoes only until a knife slides in with slight resistance, since they keep softening as they cool and mix.
🛒 E. Ingredients
🥔 Potatoes, Eggs & Peas
- 2 lb (900 g) Yukon Gold or other waxy potatoes, peeled and cut into ¾-inch (2 cm) cubes
- 1 tablespoon kosher salt, for the potato cooking water
- 4 large eggs, cold from the fridge
- 1 cup (140 g) frozen green peas (do not thaw)
- 1 tablespoon white wine vinegar (for the warm potatoes)
- 1 tablespoon extra-virgin olive oil
🐟 Tuna & Vegetables
- Two 5-oz (142 g) cans tuna packed in olive oil, well drained and flaked
- ½ cup (75 g) diced roasted red pepper (jarred is fine), patted dry
- ¼ cup (35 g) finely diced red onion
- ⅓ cup (40 g) sliced green olives (optional)
🥣 Creamy Dressing
- ½ cup (120 g) mayonnaise
- ¼ cup (60 g) plain whole-milk Greek yogurt
- 1 tablespoon fresh lemon juice
- 1 tablespoon white wine vinegar (for the dressing)
- 1 teaspoon Dijon mustard
- ½ teaspoon kosher salt, plus more to taste
- ¼ teaspoon freshly ground black pepper
🌿 Garnish
- 2 tablespoons finely chopped fresh flat-leaf parsley
- Flaky salt and freshly ground black pepper, to finish
⚠️ Scaling note: to double, use a very large mixing bowl and cook the potatoes in a 6-quart pot; keep the vinegar-and-oil step at the same ratio per pound of potatoes.
🔄 F. Ingredient Notes & Substitutions
- Potatoes: Yukon Golds are creamy yet hold their shape. Red potatoes also work. Avoid russets, which crumble when tossed.
- Tuna: Oil-packed tuna is richer and more tender than water-packed. 🔄 If you use water-packed, drain thoroughly and add 1 extra teaspoon olive oil to the dressing.
- Mayonnaise and yogurt: 🔄 Use all mayonnaise (¾ cup / 180 g) for a more classic, richer dressing, or swap the mayonnaise for more Greek yogurt for a tangier, lighter salad that is slightly looser.
- Roasted red pepper: 🔄 Diced fresh tomato (seeded) works for freshness, but add it just before serving so it does not water down the salad.
- Vinegar: 🔄 Sherry vinegar or apple cider vinegar are fine substitutes for white wine vinegar.
- 🥜 Allergens: This recipe contains egg, fish, and mustard. It does not contain nuts. A dairy-free version is in the variations below.
🍳 G. Equipment
- Large pot (4–6 quart) for the potatoes
- Small saucepan (2-quart) for the eggs
- Colander
- Large mixing bowl (at least 4-quart)

📝 H. Before You Begin (Prep & Key Techniques)
- Start the potatoes in cold water. Cold-start cooking heats the cubes evenly so the outsides do not turn mushy before the centers cook.
- Salt the water well. Potatoes are bland unless seasoned during cooking.
- Prep while the water heats. The 10 minutes to boil is ideal for peeling and cubing, chopping the onion and pepper, and draining the tuna.
- Eggs cold from the fridge. They are easier to peel after an ice bath.
- Recipe-development assumptions: The video shows potato chunks, tuna, peas, parsley, red pepper, an olive, and halved eggs in a creamy dressing. Exact quantities, the yogurt-mayonnaise ratio, and the vinegar step are original recipe-development choices, not measurements taken from the video.
👩🍳 I. Step-by-Step Instructions
🥔 Cook the Potatoes & Eggs
1. Start the potatoes. Put the potato cubes in the large pot and cover with cold water by 1 inch (2.5 cm). Add the 1 tablespoon kosher salt. Bring to a boil over high heat, about 10 minutes, then reduce to a steady simmer. Prep the vegetables during this time.
2. Cook the eggs. Place the 4 large eggs in the small saucepan, cover with cold water by 1 inch (2.5 cm), and bring to a boil over high heat. Turn off the heat, cover, and let stand for 11 minutes. ⚠️ Eggs should be fully cooked, with set whites and yolks. Transfer to the ice water for 10 minutes.

3. Simmer until tender. Once boiling, simmer the potatoes for 8–10 minutes, until a paring knife slides in with only slight resistance and the edges are just beginning to soften. They should not crumble.
4. Drain over the peas. Put the 1 cup frozen green peas in the colander and drain the potatoes directly over them. The hot water thaws the peas in about 1 minute. Shake gently and let steam off for 2 minutes.
🥣 Make the Dressing & Season the Potatoes
5. Season while warm. Transfer the potatoes and peas to the large mixing bowl. Drizzle with the 1 tablespoon white wine vinegar (for the warm potatoes) and the 1 tablespoon extra-virgin olive oil. Toss gently with the spatula and let cool for 10 minutes. 💡 Warm potatoes absorb the vinegar; cold ones will not.
6. Whisk the dressing. In the medium bowl, whisk ½ cup mayonnaise, ¼ cup plain whole-milk Greek yogurt, 1 tablespoon fresh lemon juice, 1 tablespoon white wine vinegar (for the dressing), 1 teaspoon Dijon mustard, ½ teaspoon kosher salt, and ¼ teaspoon freshly ground black pepper until smooth.
🍽️ Assemble & Chill
7. Add the tuna and vegetables. Add the flaked tuna, diced roasted red pepper, finely diced red onion, and sliced green olives (if using) to the potatoes. Pour the dressing over and fold gently until evenly coated, with some tuna flakes still visible. Fold in half of the parsley.
8. Chill. Cover and refrigerate for at least 1 hour (up to 24 hours before serving). Chilling lets the flavors meld and the dressing set slightly.
9. Peel and top with the eggs. Peel the eggs, halve them lengthwise, and taste the salad; adjust with salt, pepper, or a squeeze of lemon. Transfer to a serving bowl, arrange the egg halves on top, and sprinkle with the remaining parsley, flaky salt, and black pepper.

💡 J. Expert Tips for Success
- 💡 Cut cubes the same size. Uniform ¾-inch pieces cook at the same pace, so none turn to mush.
- 💡 Drain the tuna very well. Press the flakes in a fine-mesh sieve to avoid a loose dressing.
- 💡 Do not skip the warm-potato step. The vinegar and oil are what make the potatoes taste seasoned throughout.
- 💡 Do not over-stir. Fold with a spatula, since rough mixing breaks the cubes and makes the salad pasty.
- 💡 Dice the onion small. Finely diced red onion adds bite without dominating. Soak in cold water 5 minutes for a milder flavor.
- 💡 Taste after chilling. Cold dulls salt and acid, so adjust with lemon juice and salt just before serving.
- 💡 Add the eggs last. Topping with halves keeps the yolks neat and the salad uncluttered.
- 💡 Use fresh parsley. Dried parsley will not give the same fresh finish.
🛠️ K. Troubleshooting
| If this happens | Why | The fix |
|---|---|---|
| Potatoes are mushy | Overcooked or cut too small | Start checking at 8 minutes; cut ¾-inch cubes; fold gently |
| Salad is watery | Tuna or peppers not drained well, or potatoes not steamed dry | Drain and pat dry; let potatoes steam 2 minutes |
| Salad tastes bland | Cold mutes seasoning | Add salt, lemon juice, or a splash of vinegar after chilling |
| Dressing seems thin | Wet ingredients or too much lemon | Stir in 1 tablespoon more mayonnaise or yogurt |
| Green ring around egg yolks | Overcooked eggs | Use the 11-minute standing method, then ice bath |
| Peas look gray | Overcooked | Thaw by draining hot water over them, as in step 4 |
🌶️ L. Variations & Dietary Adaptations
- Salmon version: Replace the tuna with two 5-oz (142 g) cans drained pink salmon (skin and bones removed) and add 1 tablespoon chopped fresh dill instead of half the parsley.
- Lighter version: Use ¼ cup (60 g) mayonnaise and ½ cup (120 g) Greek yogurt, and add 1 extra teaspoon lemon juice.
- Spicy: Stir in 1 teaspoon hot paprika or ½ finely minced jalapeño.
- Mediterranean: Add ¼ cup (35 g) capers and ½ cup (75 g) halved cherry tomatoes (added just before serving).
- Extra crunch: Fold in 1 diced celery rib (about ½ cup / 50 g) and 2 tablespoons chopped dill pickles.
- 🔄 Dairy-free: Replace the yogurt with an additional ¼ cup (60 g) mayonnaise plus 1 teaspoon extra lemon juice.
- Pescatarian: Already suitable as written (contains fish and egg).
🍴 M. What to Serve With It
- Crusty bread or toasted baguette: to scoop up the creamy dressing.
- Sliced ripe tomatoes with olive oil: their acidity balances the richness.
- Grilled shrimp or chicken skewers: adds protein for a heartier meal.
- A green salad with lemon vinaigrette: crisp contrast to the soft potatoes.
- Chilled dry white wine or sparkling water with lemon: refreshing against the creaminess.
🧊 N. Storage, Make-Ahead, Freezing & Reheating
- Refrigerator: Store in an airtight container for up to 3 days. ⚠️ Refrigerate within 2 hours of making; do not leave at room temperature for more than 2 hours (1 hour if above 90°F / 32°C).
- Make-ahead: Cook the potatoes and eggs up to 1 day ahead, and refrigerate them separately. Assemble the salad up to 24 hours before serving; add the eggs on top just before serving.
- Freezing: Not recommended. Potatoes turn grainy and the mayonnaise-based dressing separates.
- Serving: This salad is served cold. Take it out of the fridge 10 minutes before serving to take the chill off the flavors.

❓ R. FAQ
Can you make tuna potato salad ahead of time? Yes, up to 24 hours ahead. Assemble the salad without the egg halves and refrigerate, then add the eggs just before serving so they stay neat.
How long does tuna potato salad last in the fridge? Up to 3 days in an airtight container. Because it contains fish, eggs, and mayonnaise, keep it cold and discard it if left out longer than 2 hours.
What type of potatoes are best for potato salad? Waxy potatoes such as Yukon Gold or red potatoes. They hold their shape when cooked and tossed; russets tend to fall apart.
Can I use water-packed tuna? Yes. Drain it very well and add 1 extra teaspoon of olive oil to the dressing to make up for the richness of oil-packed tuna.
Can I halve or double the recipe? Yes. For a half batch, use 1 lb (450 g) potatoes, 2 eggs, and half of everything else. To double, use a larger pot and mixing bowl, and keep cooking times the same.
How do I stop the potatoes from getting mushy? Cut uniform ¾-inch cubes, start them in cold salted water, and begin checking at 8 minutes of simmering. Fold gently when mixing.
Is this potato salad gluten-free? Yes, as written. Check your mayonnaise and mustard labels to confirm they are gluten-free.
