Cavatappi cold salad is a chilled pasta salad made with spiral-shaped pasta, crisp vegetables, cheddar, and a creamy, tangy herb dressing. It suits potlucks and make-ahead lunches because the ridged noodles hold onto the dressing, while a short chill lets the flavors come together.
Ingredients
- 1 lb (454 g) cavatappi pasta
- 4 qt (3.8 L) water, for boiling the pasta
- 1 tbsp (17 g) kosher salt, for the pasta water
- ¾ cup (180 g) mayonnaise
- ½ cup (120 g) sour cream
- 2 tbsp (30 ml) apple cider vinegar
- 1 tbsp (15 g) Dijon mustard
- 1 tsp (7 g) honey
- 1 tsp (1 g) dried dill
- ½ tsp (1.5 g) garlic powder
- ½ tsp (1 g) freshly ground black pepper
- ½ tsp (3 g) kosher salt, for the dressing
- 1 cup (150 g) cherry tomatoes, halved
- 1 cup (150 g) cucumber, diced into small pieces
- 1 medium red bell pepper (about 150 g), diced
- ½ cup (75 g) red onion, finely diced
- 1 cup (113 g) sharp cheddar, shredded
- ½ cup (75 g) sliced black olives, drained
- ⅓ cup (10 g) fresh parsley, chopped
Instructions
- Prepare the vegetables and dressing. Halve the tomatoes, dice the cucumber, bell pepper, and red onion, and shred the cheddar if needed. In a large bowl, whisk together the mayonnaise, sour cream, vinegar, Dijon, honey, dill, garlic powder, pepper, and ½ teaspoon salt until smooth. Set aside while you cook the pasta. This preparation takes about 25 minutes, depending on how quickly you chop.
- Boil the cavatappi. Bring the water to a boil in a large pot, which usually takes about 8 to 10 minutes. Stir in the tablespoon of kosher salt, add the pasta, and cook according to the package directions until just al dente, usually about 10 minutes. Start checking a minute before the package’s minimum time; the pasta should be tender but still hold its shape.
- Drain and cool the pasta. Drain the cavatappi in a colander, then rinse it briefly under cold running water, tossing gently, until it no longer feels warm. Shake the colander well so excess water does not thin the dressing. A quick rinse also stops the pasta from cooking further, which helps keep the spirals pleasantly firm in the finished salad.
- Combine the salad. Add the cooled pasta to the bowl of dressing and fold until the noodles are evenly coated. Add the tomatoes, cucumber, bell pepper, red onion, cheddar, olives, and parsley. Fold gently again, scraping the bottom and sides of the bowl so the vegetables and cheese are distributed throughout without crushing the tomatoes.
- Chill before serving. Cover the bowl and refrigerate the salad for 1 hour. This gives the dressing time to cling to the pasta and the flavors time to mingle. Just before serving, stir the salad well. If it seems thicker than you like, loosen it with 1 to 2 tablespoons of cold water or milk, adding a little at a time.
- Check and adjust the seasoning. Taste a forkful that includes pasta and vegetables. Add a pinch of salt, a few grinds of pepper, or a small splash of vinegar if it needs more lift. The pasta absorbs some of the dressing as it chills, so make the final adjustment after the rest rather than over-seasoning the dressing at the start.
Tips
- Cook the pasta just to al dente. Cavatappi that is very soft can break when tossed and may turn mushy after chilling. Check it near the package’s suggested cook time and drain as soon as it is tender with a slight bite. A brief cold rinse is useful here because this salad is served chilled; it is not necessary for most hot pasta dishes.
- Dry the vegetables and pasta well. Water clinging to rinsed pasta or wet cucumber can make the dressing watery. Drain the pasta thoroughly, shake off excess water, and pat washed vegetables dry before cutting. If your cucumber has large watery seeds, scoop them out before dicing.
- Keep the onion balanced. Finely diced red onion distributes its sharp flavor more evenly than large pieces. For a milder taste, soak the cut onion in cold water for 10 minutes, then drain and dry it before adding. You can also use sliced scallions, which give a gentler onion flavor.
- Hold back a little dressing if making it ahead. The pasta absorbs dressing as it sits. If preparing the salad several hours in advance, reserve about ¼ cup of dressing in a covered container and fold it in just before serving if the salad looks dry. Keep both portions refrigerated.
Serving Suggestions
Serve this salad cold or slightly cool, straight from the refrigerator after giving it a thorough stir. It works as a side dish for a cookout, picnic, sandwich lunch, or casual buffet, and the recipe makes eight generous side portions. For a meal with a few complementary textures, pair it with grilled vegetables, a green salad, corn on the cob, or simple sandwiches. If serving it outdoors, set out a smaller bowl and replenish it from the refrigerator rather than leaving the full batch on the table for an extended time.
For a neat buffet presentation, spoon the salad into a shallow serving bowl and scatter a little extra chopped parsley over the top. Keep a serving spoon with it, since the dressing and small pieces of vegetables settle as the salad sits. The creamy dressing has a mild tang from vinegar and Dijon, so it pairs well with simply seasoned dishes rather than competing with heavily sauced sides.
Variations
Make it more herb-forward: Replace the dried dill with 1 tablespoon (about 3 g) of finely chopped fresh dill, or add 1 tablespoon of chopped chives. Fresh herbs taste brighter, so add them to the dressing shortly before tossing the salad. Parsley can be increased or replaced with a mix of parsley and chives.
Use a vinaigrette instead: For a lighter, non-creamy version, whisk ⅓ cup (80 ml) olive oil with 3 tablespoons (45 ml) apple cider vinegar, 1 tablespoon Dijon, 1 teaspoon honey, and the dill, garlic powder, salt, and pepper. It will coat the pasta differently and taste sharper, so begin with about three-quarters of the vinaigrette and add more as needed.
Swap the vegetables or cheese: Diced celery, blanched broccoli florets, or thawed peas can replace some of the cucumber or bell pepper. Use the same total amount of add-ins so the pasta remains well coated. Monterey Jack gives a milder result than sharp cheddar; crumbled feta makes it saltier and tangier, so taste before adding extra salt.
Make it dairy-free: Use a dairy-free mayonnaise and an unsweetened, plain plant-based sour cream alternative, and omit the cheddar or use a dairy-free cheese. Different alternatives vary in thickness and saltiness, so whisk the dressing first and adjust its seasoning before tossing. Avoid sweetened yogurt-style products, which can make the dressing taste unexpectedly sweet.
Storage and Reheating
Refrigerate the salad in a covered, airtight container within 2 hours of preparing it. If the room or outdoor temperature is above 90°F (32°C), refrigerate it within 1 hour. Kept cold at 40°F (4°C) or below, it is best within 3 days and can generally be stored for up to 4 days. Use a clean serving utensil each time, and do not return salad that has sat out for too long to the container in the refrigerator.
This is intended to be served cold, so reheating is not recommended: heat can separate the mayonnaise-based dressing and soften the vegetables. If the chilled pasta has become firm, stir it and let only the portion you plan to eat stand at room temperature for 10 to 15 minutes; keep the rest refrigerated. Freezing is also not recommended because cucumber, tomatoes, and the creamy dressing can become watery or change texture after thawing.
Frequently Asked Questions
Can I make cavatappi cold salad the day before?
Yes. Prepare and chill it the day before, then keep it covered in the refrigerator. Since the pasta absorbs some dressing overnight, reserve about ¼ cup before tossing and stir it in before serving if needed. Add a little extra parsley at the end if you want the fresh herb flavor to stand out.
Do I have to rinse the pasta after cooking?
For this cold salad, a brief rinse under cold water is helpful: it cools the noodles quickly and stops them from cooking further. Drain them thoroughly afterward so water does not dilute the dressing. For a hot pasta dish, rinsing is usually unnecessary because it can wash away surface starch that helps sauce cling.
Can I use a different pasta shape?
Yes. Choose a short shape with curves, ridges, or openings that can hold dressing, such as rotini, fusilli, or medium shells. Cook it to al dente according to its package directions, then cool and drain it well. Very small pasta shapes can make the salad feel denser, while long strands are harder to scoop and serve.
Why does my pasta salad seem dry after chilling?
Pasta continues to absorb moisture as it rests, so a salad that looked generously dressed at first may seem drier later. Stir in the dressing you held back, or add cold water or milk a tablespoon at a time until the texture is creamy again. Taste after loosening it, since extra liquid can soften the seasoning.
Can I leave out the olives or onion?
Yes. The olives add a briny, salty note, and the red onion adds sharpness, but neither is essential to the structure of the recipe. Leave either out, or replace the olives with chopped pepperoncini for a tangier bite. If omitting both, taste the salad after chilling and adjust the salt and vinegar to keep the flavors balanced.
