This is a creamy tuna pasta salad built from pantry staples โ canned tuna, frozen peas, sweetcorn, and dried pasta โ with a mayo-yogurt dressing that actually clings to shell pasta instead of pooling at the bottom of the bowl. It comes together in under 30 minutes, feeds six, and holds up well for packed lunches the next day. If your fridge and cupboards are reasonably stocked, you probably have most of this already.
What makes this version work
Two things separate this from a bland pasta salad. First, the frozen peas go straight into the boiling pasta water for the last two minutes of cooking โ no separate pot, and they stay just tender rather than turning grey and mushy. Second, the dressing uses Greek yogurt to cut the weight of the mayo without thinning it out. That balance matters: a pure-mayo dressing can feel heavy against the briny tuna and pickles, while a pure-yogurt dressing wonโt coat the pasta properly. The small amount of olive oil in the dressing also helps it stay loose after chilling, so the salad doesnโt seize up into a stiff block in the fridge.
Troubleshooting
- Salad tastes flat after chilling: Cold dulls salt and acid. Taste again straight from the fridge and add a squeeze of lemon juice and a pinch of salt before serving โ this is almost always needed.
- Dressing slides off the pasta: The pasta wasnโt dry enough before mixing. After rinsing, shake the colander hard and let it sit for a few minutes. Surface water is the main reason dressing wonโt stick.
- Red onion is too sharp: Soak the diced onion in cold water for 10 minutes, then drain. It keeps the crunch but loses the harsh bite that can overpower everything else.
- Tuna clumps in big chunks: Drain it thoroughly, then flake it with a fork directly in the can or a small bowl before adding. Large chunks donโt distribute evenly and you end up with bites that are all tuna or none at all.
- Salad looks dry the next day: Shell pasta keeps absorbing dressing overnight. Stir in a spoonful of plain yogurt or a little olive oil to loosen it back up โ you donโt need to make a fresh batch of dressing.
Keeping leftovers crisp
Store the salad in an airtight container in the fridge and it will keep for up to three days โ dress it at the table if youโre serving a crowd, because a pre-dressed salad goes limp fast. If youโre meal-prepping individual portions, go ahead and dress them fully; just know the texture on day three will be softer than day one. The celery and pickles hold up better than youโd expect, but the peas can wrinkle slightly by day two, which affects texture more than flavor. Keep any extra fresh dill and parsley separate and add them just before eating โ herbs stored in a dressed salad turn dark and slimy within 24 hours.

For the Dressing:
- ยฝ cup mayonnaise full-fat preferred
- โ cup plain Greek yogurt 2% or whole milk
- 1 tbsp Dijon mustard
- 2 tbsp fresh lemon juice
- 1 tbsp extra-virgin olive oil
- 1 tsp honey or sugar
- ยฝ tsp garlic powder
- ยพ tsp fine sea salt plus more to taste

- ยฝ cup celery, small dice
- โ cup dill pickles (gherkins), chopped
- 1 tbsp capers, drained and roughly chopped optional but recommended
- 2 tbsp fresh dill, chopped
To Finish:
- 1 tsp lemon zest, finely grated
- 2 tbsp flat-leaf parsley, chopped
- ยผ tsp crushed red pepper flakes optional
Instructions
- Cook the Pasta and Peas: Bring a large pot of water to a rolling boil and season with the kosher salt. Add the pasta and cook, stirring occasionally, until al dente, about 8โ10 minutes. In the last 2 minutes of cooking, add the frozen peas to the pot. Drain in a colander, rinse under cold water until cool, and shake well to remove excess water.
- Whisk the Dressing: In a small bowl, whisk together the mayonnaise, Greek yogurt, Dijon, lemon juice, olive oil, honey, garlic powder, sea salt, and black pepper until smooth and emulsified, 30โ45 seconds.
- Prep the Mix-Ins: While the pasta cooks, flake the drained tuna with a fork. Drain the sweetcorn thoroughly. Finely dice the red onion and celery; chop the pickles and dill. Keep ingredients ready for assembly.
- Combine and Coat: In a large mixing bowl, add the cooled pasta and peas, tuna, sweetcorn, red onion, celery, pickles, capers, and dill. Pour over the dressing and toss gently with a spatula until every piece is glossy and evenly coated, 1โ2 minutes.
- Finish and Season: Fold in the lemon zest and parsley. Taste and adjust: add a pinch more salt, a twist of pepper, or an extra squeeze of lemon for brightness. For a subtle kick, sprinkle in the red pepper flakes.
- Serve: Spoon into a chilled bowl or pack into containers. Serve immediately, or cover and refrigerate until ready; the flavors meld beautifully as it rests.
Notes
Chefโs Tips:
- Shape Matters: Choose short pasta with nooks (small shells, elbows, cavatappi) so the dressing clings and the peas and corn tuck in.
- Cool with Purpose: For cold salads, a quick cold rinse stops carryover cooking and prevents gummy starch. Drain very well so the dressing doesnโt thin.
- Season Smartly: Tuna, pickles, and capers bring salinityโtaste before adding extra salt to the dressing.
- Customize: Add chopped bell pepper, sliced scallions, or halved cherry tomatoes. Swap dill pickles for cornichons, or add 1 tsp caper brine for extra tang.
- Make-Ahead: The salad keeps 2โ3 days refrigerated. For the glossiest finish, reserve 2 tbsp dressing to fold in just before serving.
- Using Water-Packed Tuna? Add 1 tbsp olive oil to the dressing for silkiness.
- Gluten-Free: Use gluten-free short pasta and rinse gently to remove excess starch.

Common questions
Can I use tuna in water instead of tuna in olive oil?
Yes, water-packed tuna works fine. Drain it well and stir in an extra teaspoon of olive oil when you mix the dressing to compensate for the lost fat, otherwise the salad can taste a little dry.
What pasta shape can I use if I donโt have shells or elbows?
Any short pasta with ridges or curves will do โ rotini, farfalle, or cavatappi all catch the dressing well. Avoid long pasta like spaghetti or smooth shapes like penne liscia, which let the dressing slip off.
Can I skip the capers or pickles if I donโt have them?
You can skip either one, but try to keep at least one briny element or the salad tastes flat against the creamy dressing. A few sliced green olives or a teaspoon of pickle brine stirred into the dressing will do the same job.
Is there a substitute for Greek yogurt in the dressing?
Sour cream is the closest swap โ same tang, similar thickness. Regular plain yogurt also works but the dressing will be slightly thinner, so reduce the lemon juice by half a teaspoon to keep it from getting too loose.
Can I make this ahead for a picnic or potluck?
Make it up to 24 hours ahead and keep it refrigerated. Pack the fresh herbs separately and stir them in just before serving so they donโt wilt and discolor the salad.
Can I use canned peas instead of frozen?
Yes, though canned peas are softer and wonโt give the same slight pop. Drain and rinse them well, then fold them in at the end rather than cooking them โ theyโre already soft enough and will turn mushy if boiled.
