Easy Tuna Pasta Salad with Peas

This easy tuna pasta salad is made for picnics, potlucks, barbecues, and any warm-weather meal where you want something cool, creamy, and simple to put together. Medium pasta shells, tuna packed in water, sweet peas, crisp celery, and red onion come together with a light lemon-dill dressing that has just the right balance of creamy, tangy, and fresh flavors.

There is something especially inviting about the beginning of summer: swimming pools, long lazy days, backyard barbecues, and gatherings that revolve around a table of shareable food. Summer salads, grilled recipes, and simple pasta salads all belong in that season, and this cold tuna pasta salad fits right in.

The recipe makes 12 servings, takes 20 minutes of prep time, and has a listed total time of 20 minutes. It is easy enough to assemble for a casual gathering, but the finished salad still has plenty of texture from the vegetables and peas. The dressing is made with light mayonnaise, yogurt, lemon juice, and dill, so it coats the pasta without needing a long ingredient list. Make it ahead for a gathering, or keep the leftovers in the refrigerator for a convenient lunch the next day.

Why You Will Love This Tuna Pasta Salad

This is a cold pasta salad with light, familiar flavors and a creamy dressing that comes together in a small bowl. You do not need to cook a separate sauce or thaw the peas in advance. Once the shells are cooked and cooled, the rest is a matter of chopping, whisking, and tossing.

The shells are useful here because their shape holds onto the dressing and little pieces of peas and vegetables. You can use another small pasta if you prefer, but medium shells work especially well for this kind of salad. Tuna gives the salad its savory seafood flavor, while lemon and dill keep the dressing bright rather than heavy.

It is also a practical make-ahead side. The salad can be prepared up to 24 hours before a get-together, with one important consideration: the pasta absorbs some of the dressing as it sits. For the freshest texture, you can prepare the pasta, tuna, peas, celery, and onion ahead of time, then wait to add the dressing until shortly before serving. If you dress the salad in advance, it will still be useful for a picnic or gathering, but keep that absorption in mind.

Tuna Pasta Salad Ingredients

For the Salad

• 1 pound medium shells: Cook the pasta, drain it, and rinse it with cold water. Another small pasta can be used, although shells are a particularly good shape for this salad.
• 12 ounces tuna packed in water: Drain the tuna and use the dry weight listed on the can. Tuna packed in oil is not the right choice for this version because it changes the flavor and consistency of the finished salad.
• 1 cup frozen peas: Add the peas while they are still frozen. They thaw very quickly when mixed with the other ingredients, and thawing them first can add more moisture than you want.
• 2 stalks celery, diced: Celery adds a crisp bite. If you do not enjoy celery, shredded carrots are a possible replacement.
• 1/2 small red onion, diced: Red onion brings a sweet tang to the salad. It can be left out or replaced with green onion if you prefer.

For the Dressing

• 1 cup light mayonnaise: Light mayonnaise works well in this dressing and brings the creamy texture you need. Usually it behaves the same as regular mayonnaise, brings the same flavor, and cuts out a little bit of calories and fat.
• 1/4 cup plain yogurt: Yogurt adds both zip and creaminess. Its flavor is different from mayonnaise, and the two work well together in the dressing.
• 1 teaspoon lemon juice: This small amount adds freshness and lifts the creamy ingredients.
• 1 tablespoon fresh dill or 1 teaspoon dry dill: Dill pairs beautifully with seafood. Use the fresh or dry amount that suits what you have available.
• 1 teaspoon salt and 1/4 teaspoon black pepper: Start with half of the salt and pepper, taste the dressing, and add the rest to taste.

The ingredient list is short, but each part has a job. The pasta gives the salad its substantial base, the tuna supplies the main savory flavor, and the peas, celery, and onion keep each bite from becoming one-note. In the dressing, mayonnaise provides body, yogurt brings a little tang, lemon adds freshness, and dill gives the salad its seafood-friendly herbal note.

How to Make Tuna Pasta Salad

1. Cook the shells. Cook the pasta according to the package instructions, being careful not to overcook it. Pasta for a cold salad should hold its shape instead of becoming soft or fragile when tossed with the other ingredients. Drain the shells, then rinse them with cold water. The cold rinse cools the pasta for the salad and helps you move on to the mixing step without waiting for it to cool on its own.
2. Whisk the dressing. Add the light mayonnaise, plain yogurt, lemon juice, dill, salt, and black pepper to a small bowl. Whisk until the ingredients are combined and the dressing looks smooth. Taste it before it goes into the salad. Adjust the seasonings as needed, keeping in mind that starting with half of the salt and pepper gives you more control over the final flavor.
3. Combine the salad ingredients. Add the cooled noodles, drained tuna, frozen peas, diced celery, and diced red onion to a large bowl. The peas can go in straight from the freezer; there is no need to thaw them first.
4. Add the dressing and toss. Pour the dressing over the pasta mixture. Toss everything together until the dressing coats the noodles and the tuna and vegetables are distributed throughout the bowl. Serve the salad as a cool side dish, or cover it and refrigerate it if you are making it ahead.

That is the complete method: cook and cool the shells, whisk the dressing, combine the salad ingredients, and toss. The most important process details are not overcooking the pasta, using tuna packed in water, and tasting the dressing before adding it to the larger bowl.

Tips for Success

• Do not overcook the shells. Follow the package directions and keep an eye on the pasta. Overcooked shells can lose their shape when rinsed and tossed, while properly cooked pasta gives the salad a better texture.
• Rinse with cold water. Drain the pasta and rinse it with cold water before combining it with the other ingredients.
• Use tuna packed in water. Check the can before you begin, and drain the tuna well. Tuna packed in oil will really change the flavor and consistency of this recipe, so it should not be treated as an interchangeable choice here.
• Leave the peas frozen. Frozen peas thaw quickly once they are mixed into the salad. Adding them frozen also avoids introducing the extra moisture that can come from thawing them separately.
• Season the dressing before dressing the salad. Begin with half the listed salt and pepper, whisk, and taste. Add more as needed. It is much easier to adjust the seasoning while the dressing is still in a small bowl than after it has been spread through a large quantity of pasta.
• Think about when you want to add the dressing. Pasta absorbs some of the dressing as it rests. If you want the salad to be as creamy as possible at serving time, keep the dressing separate until right before serving, especially when preparing the salad the day before.

Variations and Substitutions

The recipe has several flexible points, but each substitution changes the finished salad in its own way. Use the options below according to your preferences rather than assuming every swap will taste identical.

• Change the pasta: A different kind of small pasta can replace the medium shells. Shells are recommended because they work well in this type of pasta salad, but the goal is to keep the pieces small enough to combine comfortably with the tuna and vegetables.
• Replace the celery: If celery is not your favorite, use shredded carrots instead. The carrots bring a different flavor and texture while filling the same fresh vegetable role.
• Leave out or change the onion: You can omit the red onion, or use green onion in its place. Red onion contributes a sweet tang, so leaving it out will make the salad milder.
• Use dry dill: Replace 1 tablespoon of fresh dill with 1 teaspoon of dry dill. If you skip dill entirely, use 1/2 teaspoon dry tarragon and 1/2 teaspoon dry parsley instead. That combination gives the dressing a different herbal direction.
• Try Miracle Whip: Miracle Whip can replace the mayonnaise and will provide the texture and consistency needed for the dressing. It changes the taste quite a bit, though, so taste the dressing before adding it to the pasta mixture to be sure you like the flavor.
• Replace the yogurt: Sour cream is a suitable replacement if you do not like yogurt. It will keep the creamy element of the dressing while changing its tang.
• Replace the tuna: Chicken can stand in for the tuna if you are not a fan of tuna. The finished salad will no longer have the same seafood flavor, but the pasta, vegetables, and creamy dressing still give you the same general format.

Storage and Make-Ahead

This tuna pasta salad can be made up to 24 hours in advance of a get-together. If you prepare it the day before, remember that the pasta will absorb some of the dressing while it rests. One practical option is to make the salad with the noodles, tuna, peas, celery, and onion, then add the dressing right before serving. This keeps more of the dressing on the pasta instead of letting it disappear into the noodles overnight.

Store leftovers in the refrigerator. They should be eaten within four days of making the salad. As with any leftovers, use your best discretion when deciding whether they are still suitable to eat.

Serving Suggestions

Serve this cold salad as a side dish at a picnic, potluck, barbecue, or other summer gathering. Its 12-serving yield makes it useful when several people are eating, and the combination of pasta, tuna, and vegetables makes it feel more substantial than a simple leafy salad. Set it out alongside grilled recipes or other summer foods, or portion leftovers for work the day after a picnic.

Frequently Asked Questions

Can I use pasta other than medium shells?

Yes. A different small pasta can be used. Medium shells are a particularly good choice for this salad because their shape works well with the creamy dressing, tuna, peas, celery, and onion.

Do I need to thaw the frozen peas?

No. Add the peas while they are frozen. They thaw very quickly when tossed with the other ingredients, and thawing them separately can add more moisture than you want in the salad.

Why does the tuna need to be packed in water?

Tuna packed in water is the specified choice for this recipe. Tuna packed in oil will significantly change both the flavor and the consistency of the salad, so choose water-packed tuna and drain it before adding it to the bowl. The 12-ounce quantity refers to the dry weight listed on the can.

Can I use dry dill instead of fresh?

Yes. Use 1 teaspoon of dry dill in place of 1 tablespoon of fresh dill. If you do not want dill at all, use 1/2 teaspoon dry tarragon and 1/2 teaspoon dry parsley as the suggested alternative.

What can replace the mayonnaise or yogurt?

Miracle Whip can replace the mayonnaise and will give the dressing the texture and consistency you need, but it will change the taste quite a bit. Taste the dressing before mixing it into the salad. Sour cream is a possible replacement for the plain yogurt; it keeps the dressing creamy while changing its flavor.

Can I make tuna pasta salad the day before, and how long will leftovers keep?

Yes. Make it up to 24 hours before a gathering. Since the pasta absorbs some of the dressing, consider preparing the salad components in advance and adding the dressing right before serving. Keep leftovers refrigerated and plan to eat them within four days of making the salad, using your best discretion with any leftovers.
