This is a cold pasta salad built around tinned tuna, sweetcorn, and a creamy lemon-mustard dressing โ the kind of thing you can pull together in about 45 minutes, most of which is hands-off. It uses fusilli or rotini, which grip the dressing better than smooth pasta shapes, and the mix of mayonnaise and Greek yogurt keeps it rich without feeling heavy. If you need a reliable make-ahead lunch or a fast weeknight dinner that doesnโt require turning on the oven, this does the job.
What makes this version work
Two things matter here. First, the dressing uses Greek yogurt alongside mayonnaise rather than mayo alone โ this cuts the richness slightly and adds just enough tang to balance the sweetness of the corn, without making the dressing taste low-fat or thin. Second, you fold the dressing into the pasta while itโs still slightly warm. Warm pasta is porous; it pulls the dressing in rather than just wearing it on the surface. The result is a salad that tastes seasoned all the way through, not just coated on the outside. Neither of these steps takes extra time โ they just require doing things in the right order.
Ingredient notes
- Tuna packed in water: Oil-packed tuna will make the dressing greasy and throw off the balance. Drain water-packed tuna very well โ press it in the strainer โ or the dressing will turn watery within an hour.
- Greek yogurt: Use 2% or full-fat. Nonfat yogurt separates when mixed with acid and turns the dressing grainy.
- Apple cider vinegar: A small amount, but it does real work here โ it sharpens the dressing in a way that lemon juice alone doesnโt. Donโt skip it or substitute white wine vinegar, which is sharper and less rounded.
- Fresh lemon zest: This is worth doing. Bottled lemon juice gives you acid; zest gives you actual lemon flavor. A microplane takes 30 seconds.
- Parsley vs. dill: Dill is the better call if youโre serving this to adults โ it pairs more naturally with tuna. Parsley works fine and is more kid-friendly.
Common problems and fixes
- Dressing tastes flat after chilling: Cold mutes salt and acid. Always taste again right before serving and add a pinch of salt and a small squeeze of lemon juice โ not more mayo.
- Salad is dry after a few hours: The pasta keeps absorbing dressing as it sits. Reserve two or three tablespoons of dressing separately and stir it in just before serving rather than adding it all upfront.
- Tuna clumps in large chunks: Flake it thoroughly before adding โ use a fork and break it down to small, even pieces. Large chunks donโt distribute evenly and you end up with bites that are all tuna or none at all.
- Red onion is too sharp: Soak the diced onion in cold water for 10 minutes, then drain and pat dry. This removes the harsh bite without losing the flavor or crunch.
- Celery goes soft overnight: Add celery just before serving if youโre making this more than a few hours ahead. It loses its snap faster than any other ingredient in this salad.
Keeping leftovers crisp
Store the salad in an airtight container in the fridge for up to three days. By day two, the pasta will have absorbed most of the dressing โ stir in a tablespoon of mayo or a splash of water to loosen it before eating. The peas hold up well, but if you added celery, it will soften noticeably by day two; for meal-prep purposes, keep sliced celery in a separate small container and stir it in per portion. Dress it at the table if youโre serving this to guests โ a fully dressed salad left out for more than 20 minutes starts to look dull and the dressing pools at the bottom. For packed lunches, the salad travels fine fully dressed as long as it stays cold.
Creamy Tuna & Sweetcorn Pasta Salad
Equipment
- Large pot (at least 6 qt)
- Colander
- Large mixing bowl
- Medium bowl or measuring jug
- Whisk
- Chef's Knife
- Cutting board
- Measuring cups and spoons
- Citrus zester or microplane
- Rubber Spatula
Ingredients
For the Pasta & Salad Components:
- 1 tbsp kosher salt for pasta water
- 12 oz dried short pasta (fusilli or rotini) al dente texture holds dressing well
- 1 ยฝ cups sweetcorn kernels canned (drained) or frozen (thawed)
- 10 oz tuna packed in water well-drained and flaked
- โ cup red onion finely diced
- ยฝ cup celery thinly sliced
- ยฝ cup peas thawed; optional
- ยผ cup fresh parsley chopped
- 1 tbsp extra-virgin olive oil to coat warm pasta
For the Creamy Dressing:
- ยพ cup mayonnaise quality, full-fat for best texture
- ยฝ cup plain Greek yogurt 2% or full-fat
- 2 tsp Dijon mustard
- 2 tbsp fresh lemon juice
- 1 tsp lemon zest finely grated
- 1 tsp apple cider vinegar
- 1 tsp honey balances acidity
- ยฝ tsp black pepper freshly ground
- ยพ tsp kosher salt plus more to taste
Instructions
- Bring Water to a Boil: Fill a large pot with at least 4 qt water and add 1 tbsp kosher salt. Bring to a rolling boil at 212ยฐF / 100ยฐC.
- Cook the Pasta: Add the pasta and stir to prevent sticking. Cook until al dente, 10 minutes (check package). In the last 1 minute of cooking, stir in frozen peas to blanch; if using canned corn instead of frozen, do not boilโadd it later.
- Drain, Oil, and Cool: Drain the pasta (and blanched peas) in a colander and shake off excess water. Transfer to a large bowl, drizzle with 1 tbsp olive oil, and fold to coat so it doesnโt clump. Let cool until just warm, 5โ7 minutes.
- Whisk the Creamy Dressing: In a medium bowl, whisk together mayonnaise, Greek yogurt, Dijon, lemon juice, lemon zest, apple cider vinegar, honey, salt, and pepper until smooth and emulsified, about 30โ45 seconds.
- Prepare Mix-Ins: Flake the well-drained tuna. Finely dice the red onion, slice the celery, and chop the parsley. If using canned corn, rinse and drain; if using thawed frozen corn, pat dry.
- Combine the Salad: Add the pasta to the large mixing bowl along with tuna, corn, onion, celery, parsley, and any remaining peas. Pour over the dressing and fold gently with a spatula until every curve of pasta is glossed and coated, about 1โ2 minutes.
- Taste and Balance: Taste and adjust seasoning with a pinch more salt, black pepper, or a squeeze of lemon for brightness. The flavor should be creamy, lightly tangy, and well-seasoned.
- Chill to Set: Cover and refrigerate for 20 minutes to let the flavors meld and the dressing slightly thicken. Your refrigerator should be around 37ยฐF / 3ยฐC.
- Serve: Stir, garnish with extra parsley and cracked pepper, and serve cool or at room temperature. For best texture, enjoy within 3 days, kept refrigerated.
Notes
Chefโs Tips:
- Shape Matters: Choose short, ridged pasta (fusilli, rotini, cavatappi) to trap the creamy dressing.
- Season the Water: Properly salted water is your first seasoning layerโkeep it salty like the sea.
- Canned vs. Frozen Corn: Add canned corn straight to the bowl; blanch frozen corn for 30โ60 seconds in the pasta water if you prefer it hot and juicy.
- Keep it Creamy, Not Gloopy: Toss pasta while itโs just warm so it absorbs flavor, then chill to set. If the salad tightens after chilling, loosen with a splash of lemon juice or 1โ2 tsp water.
- Make it Your Own: Add diced dill pickles, capers, or roasted red peppers for extra zing; swap parsley for dill.
- Meal Prep: Store in an airtight container up to 3 days. Stir before serving and refresh with a pinch of salt and a squeeze of lemon.
- Gluten-Free: Use your favorite gluten-free short pasta and cook on the low end of the time for best bite.

Your questions, answered
Can I use canned sweetcorn instead of frozen?
Yes โ canned sweetcorn works well and is what most people use. Just drain it thoroughly before adding; excess liquid from the can will water down the dressing.
Can I make this the night before?
Yes, and it actually tastes better after a few hours in the fridge once the flavors settle. Hold back a couple of tablespoons of dressing and stir them in the next day, since the pasta absorbs a lot overnight.
What pasta shape works if I donโt have fusilli or rotini?
Farfalle, penne, or cavatappi all work. Avoid long pasta like spaghetti or flat shapes like farfalle rigate โ they donโt hold the creamy dressing as well and make the salad harder to serve.
Is there a dairy-free swap for the Greek yogurt?
Plain unsweetened coconut yogurt or a thick oat-based yogurt works as a 1:1 substitute. Avoid anything thin or sweetened โ it will make the dressing runny and slightly sweet in the wrong way.
How do I keep the salad from tasting bland?
Season the pasta water generously โ it should taste noticeably salty โ and taste the finished salad after itโs been in the fridge, not just right after mixing. Cold dulls seasoning, so a final pinch of salt and squeeze of lemon before serving makes a real difference.
