Step-by-Step Instructions
Step 1: Simmer potatoes and carrot
Scrub the potatoes and leave them whole and unpeeled. Place in a pot and cover by 1 inch (2.5 cm) with cold water. Add 1 tbsp kosher salt. Bring to a boil over medium-high, then reduce to a lively simmer (about 190–200°F / 88–93°C). Cook 18–22 minutes total, until a skewer slides in with gentle resistance. Add the whole peeled carrot to the same pot during the last 8–10 minutes; remove it earlier if tender. Drain well.
Step 2: Blanch peas and cook optional eggs
While the potatoes simmer, bring a small pot of water to a boil. Add the peas and cook 2–3 minutes until bright green and tender. Transfer to an ice bath to stop cooking; drain and pat dry. For optional eggs, lower them into boiling water and cook exactly 10 minutes. Chill in ice water, then peel and chop.
Step 3: Cool, peel, and dice
Return the drained potatoes to the warm pot off heat and let them steam-dry for 5 minutes. When cool enough to handle but still warm, peel by rubbing or scraping off the skins. Dice potatoes into 1/2-inch (1.25 cm) pieces. Dice the carrot into smaller 1/4-inch (6 mm) pieces for even distribution. Place both in a wide mixing bowl (a wide bowl makes gentle folding easier). If using eggs, chop and set aside.
Step 4: Make the creamy dressing
In a small bowl, whisk together mayonnaise, sherry vinegar, olive oil, 1/2 tsp kosher salt, pepper, and optional Dijon. Taste; it should be creamy with a gentle tang. If you prefer a brighter finish, add up to 1/2 tsp more vinegar.
Step 5: Fold the salad (keep it chunky)
Drain the tuna well and flake it into large pieces. Add tuna and peas to the potatoes and carrot. Spoon in about 2/3 of the dressing and fold gently with a spatula, turning the bowl as you go so the potatoes don’t mash. Add more dressing as needed to achieve a lush, creamy coating while keeping some texture. Taste and adjust salt to preference.
Step 6: Chill to set the flavor
Cover and refrigerate for at least 60 minutes at 37–40°F (3–4°C). This rest firms the salad and helps the flavors meld. It can be chilled up to 24 hours before serving.
Step 7: Garnish and serve tapas-style
Transfer to a shallow serving dish and smooth the top with the back of a spoon, then create a few swoops. Dot with roasted red pepper strips, halved green olives, and chopped parsley. Drizzle a little extra-virgin olive oil. Serve chilled with toasted baguette slices or potato chips.
Pro Tips
- Use waxy potatoes (Yukon Gold or new potatoes) and cook them whole and unpeeled to prevent waterlogging and crumbling.
- Steam-dry the potatoes after draining so the dressing clings instead of thinning out.
- Fold gently, don’t stir aggressively—keeping larger flakes of tuna and intact cubes of potato makes the texture luxurious.
- Season at the end; olives and tuna add salt, so taste after folding in the briny elements.
- For party service, chill the salad, then garnish just before serving so peppers and olives look fresh and glossy.
Variations
- Aioli Twist: Replace 2–3 tbsp of the mayonnaise with garlicky aioli and finish with a pinch of smoked paprika.
- Vegetarian: Skip the tuna and add 1 cup (165 g) canned chickpeas (rinsed and dried) plus extra roasted red pepper.
- Basque-Style: Add finely chopped cornichons and a few sliced piparras (pickled peppers) for a tangy bite.
Storage & Make-Ahead
Refrigerate in an airtight container for up to 3 days at 34–40°F (1–4°C). Do not freeze. For best presentation, fold in garnishes just before serving. This salad is excellent made 12–24 hours ahead.
