This is a creamy, cold macaroni salad built on elbow pasta, canned tuna, celery, red onion, dill pickles, and sweet peas, all coated in a mayo-sour cream dressing sharpened with Dijon, pickle brine, and lemon juice. It takes about 30 minutes of active work and feeds six. The honest reason to make it: it holds up in the fridge for days and tastes better the next day than it does fresh.
Before you start
Two things decide whether this salad is good or just okay. First, the pasta needs to be genuinely dry before it meets the dressing โ rinsing stops the cooking, but water still clings to the surface, and that water will thin your dressing and make the salad watery by day two. Spread the rinsed elbows on a sheet pan and give them a full five minutes to air out, not just a quick shake in the colander. Second, taste the dressing on its own before you combine everything. The tuna and pickles both carry salt, so the dressing should taste slightly underseasoned at this stage โ it will come into balance once everything is mixed and chilled.
Troubleshooting
- Dressing soaks in and the salad looks dry after chilling: Elbow macaroni keeps absorbing moisture as it sits. Hold back about two tablespoons of mayo when you first mix, then stir it in just before serving to bring the creaminess back.
- Tuna clumps in big chunks: Drain the cans thoroughly, then flake the tuna directly onto a plate with a fork before adding it to the bowl. Breaking it up separately gives you even distribution without overworking the pasta.
- Red onion tastes sharp and raw: Soak the minced onion in cold water for ten minutes, then pat dry. It keeps the crunch but loses the harsh bite that can overpower everything else.
- Peas turn dull and mushy: The recipe adds them in the last minute of boiling, which is correct โ but if your peas are still frozen solid when they go in, add them 90 seconds before the end instead. They should be just thawed and bright green, not cooked through.
- Salad tastes flat even after seasoning: A flat mayo-based salad almost always needs more acid, not more salt. Add a small extra squeeze of lemon juice or a few more drops of pickle brine and stir well before reaching for the salt shaker.
Leftovers and meal prep
Store the finished salad in an airtight container in the refrigerator. It keeps well for up to four days, and the flavor genuinely improves after the first overnight rest as the dressing works into the pasta. If you are making it specifically to eat across the week, keep the fresh dill garnish separate and add it to each portion when you serve โ dried-out dill on day three is not worth it. The celery and onion stay crisp through day two with no special handling; by day four they soften noticeably, which some people prefer and others do not. One firm opinion here: do not dress the full batch if you plan to serve half of it at a gathering and save the rest โ a pre-dressed salad that sits out for two or more hours then goes back in the fridge loses its texture faster than one that was chilled the whole time. If you are feeding a crowd and want leftovers, dress only what you need at the table and refrigerate the rest undressed, then toss with the reserved dressing the next day.
Creamy Deli-Style Tuna Macaroni Salad

- Cutting board
- Measuring cups and spoons
- Rubber Spatula
- Sheet pan (for rapid cooling)
Ingredients
For the Pasta & Mix-Ins:
- 12 oz elbow macaroni dry
- 1 tbsp kosher salt for pasta water
- 1 cup frozen peas add in last minute of boiling
- 1 cup celery finely diced (about 2 stalks)
- โ cup red onion finely minced
- ยฝ cup dill pickles finely chopped
- 10 oz canned tuna in water drained well and flaked
For the Dressing:
- ยพ cup mayonnaise
- ยผ cup sour cream
- 1 tbsp Dijon mustard
- 1 tbsp lemon juice freshly squeezed
- 1 tbsp pickle brine from the pickle jar
- ยพ tsp kosher salt plus more to taste
- ยฝ tsp black pepper freshly ground
- ยผ tsp garlic powder
- ยฝ tsp paprika sweet; plus more for garnish
- 2 tbsp fresh dill finely chopped
- 1 tsp granulated sugar optional, to balance acidity
For Finishing:
- 1 tbsp fresh dill finely chopped, for garnish
- ยผ tsp paprika for dusting on top
Instructions
- Cook the Macaroni: Bring a large pot of water to a rolling boil, season with the 1 tbsp kosher salt, and add the 12 oz elbow macaroni. Cook until just tender, about 9โ10 minutes. In the final 60 seconds, stir in the peas to brighten and heat through. Drain well; rinse under cold water to stop cooking, then spread on a sheet pan to steam off excess moisture.
- Prep the Mix-Ins: While the pasta cooks, finely dice the celery and red onion, chop the dill pickles, and flake the drained tuna with a fork so it distributes evenly without large chunks.
- Whisk the Dressing: In a medium bowl, combine mayonnaise, sour cream, Dijon, lemon juice, pickle brine, kosher salt, black pepper, garlic powder, paprika, fresh dill, and sugar. Whisk until smooth and emulsified with no streaks.
- Combine: Add the cooled macaroni to a large mixing bowl with the peas, celery, red onion, pickles, and tuna. Scrape in the dressing and fold gently with a rubber spatula until every curve of pasta is glossy and coated without crushing the tuna.
- Adjust Seasoning: Taste and fine-tune with a pinch more kosher salt, pepper, or lemon as needed. The flavor should read creamy, lightly tangy, and balanced by a soft sweetness.
- Chill and Serve: Transfer to a serving bowl, smooth the top, and dust with a little paprika and fresh dill. Cover and chill for 30 minutes at 37โ40ยฐF / 3โ4ยฐC so flavors marry and the dressing clings. Serve cold.
Notes
Chefโs Tips:
- Season the Water Properly: Salting the boil seasons the pasta from within, so the salad tastes lively, not flat.
- Cool, Then Dry: After rinsing, spread the pasta so steam escapes; excess water thins the dressing.
- Balance is Key: Pickle brine and lemon sharpen the mayo base; a pinch of sugar softens the edges without making it sweet.
- Crisp Texture Insurance: Finely dice celery and onion for crunch that integrates instead of dominating each bite.
- Make-Ahead: The salad improves after a brief rest. If holding overnight, reserve 2โ3 tbsp dressing to refresh just before serving.
- Storage: Keep refrigerated and consume within 3โ4 days; stir before serving.
Your questions, answered
Can I make this salad the night before?
Yes, and it is actually better the next day. Make the full recipe, cover it tightly, and refrigerate overnight โ the dressing thickens and clings more evenly after a few hours. Just stir it well before serving and add the fresh dill garnish at that point rather than the night before.
What kind of canned tuna works best here?
Tuna packed in water is the right call for this recipe โ oil-packed tuna adds extra fat that can make the mayo dressing feel greasy and heavy. Solid white albacore gives you larger, meatier flakes, while chunk light tuna breaks down finer and blends more evenly into the salad; either works depending on the texture you prefer.
Can I substitute Greek yogurt for the sour cream?
Full-fat plain Greek yogurt works as a direct swap for the sour cream in equal measure. The salad will taste slightly tangier and a little less rich, so you may want to add the optional teaspoon of sugar to keep the dressing balanced.
