There’s a certain kind of comfort that lives in a big bowl of pasta: familiar, generous, and easy to share. Imagine a late afternoon where kids tumble through the back door and neighbors drift in with a bottle of iced tea. You reach for a chilled pasta salad, fork ready, and suddenly the kitchen fills with soft conversation and the smell of sweet peppers and vinaigrette. That’s the kind of togetherness this creamy pasta salad brings — casual, satisfying, and just right for porch nights or potluck afternoons.
I love recipes that travel well from fridge to picnic basket and that don’t demand chef-level skills to shine. This rotini-based salad balances tangy Italian dressing with a spoonful of mayo and a hint of Cajun spice so every bite tastes wide and welcoming. The colorful veggies give it pop and crunch, the cucumbers offer cool contrast to the creamy dressing, and the grape tomatoes burst with summer brightness. Make it a day ahead, and the flavors mellow and marry beautifully, making it one of those dishes that actually gets better with a little patience.

Ingredients
- 8 oz Garden Rotini Pasta (Can substitute with fusilli or penne.)
- 1 medium Red Onion (Can use green onions for milder flavor.)
- 1 medium Cucumber (Zucchini can be used instead.)
- 1 pint Grape Tomatoes (Cherry tomatoes can be swapped.)
- 1 medium Yellow Bell Pepper (Any bell pepper variety can be used.)
- 1 cup Italian Vinaigrette Dressing (Can substitute with other vinaigrettes.)
- 1/2 cup Mayonnaise (Greek yogurt can be used for a lighter option.)
- 1 tsp Cajun Seasoning (Can substitute with Old Bay seasoning.)
- 1/2 tsp Ground Black Pepper (Omit if sensitive to spice.)
- 1 tbsp White Sugar (Honey or agave syrup can be used as alternatives.)
Instructions
-
Bring a large pot of salted water to a rolling boil.
-
Add the rotini and cook until al dente according to package directions, usually 8 to 10 minutes.
-
Drain the pasta and rinse under cold water until the pasta feels cool to the touch to stop the cooking and prevent clumping.
-
Transfer the cooled pasta to a large mixing bowl and toss gently to loosen the spirals.
-
Peel the red onion and slice it thinly; if you prefer milder onion flavor, soak the slices in ice water for 5 minutes then drain.
-
Trim and dice the cucumber into bite-sized pieces.
-
Halve the grape tomatoes and remove the seeds only if they seem watery; otherwise leave them for juice and flavor.
-
Core and dice the yellow bell pepper into roughly the same size as the cucumber for even texture.
-
In a small bowl, whisk together the Italian vinaigrette, mayonnaise, Cajun seasoning, ground black pepper, and white sugar until smooth and slightly glossy.
-
Pour the dressing over the pasta while the bowl sits on the counter and stir to coat every piece evenly.
-
Add the chopped red onion, cucumber, grape tomatoes, and yellow bell pepper to the bowl and fold gently until vegetables distribute evenly.
-
Taste and adjust seasoning: add a pinch of salt or another 1/4 teaspoon of Cajun seasoning if you want more heat.
-
Cover the bowl and refrigerate at least 1 hour to let flavors meld; chill 3 to 4 hours or overnight for best results.
-
Before serving, give the salad a final gentle stir and add a splash more vinaigrette if the pasta absorbed too much dressing while chilling.
-
Serve chilled or slightly cool; garnish with a few extra black pepper turns or sliced green onions if desired.
How to serve this dish
Serve this creamy pasta salad as a centerpiece side alongside grilled proteins like chicken thighs or burgers. It pairs beautifully with smoky barbecue flavors and provides a bright counterpoint to rich mains. For a lighter picnic plate, spoon it onto lettuce leaves as a salad wrap. You can also offer it in a buffet with scoops of coleslaw, corn salad, and crusty rolls; the colors help build an attractive spread. When you bring this to a potluck, add a small bowl of extra dressing so guests can refresh their portions if the salad sits out for a while.
How to store it properly
Store leftovers in an airtight container in the refrigerator and use within three to four days. Keep the salad chilled; the mayonnaise and dairy-free vinaigrette base both hold up well for a few days but lose texture after that. Do not freeze this salad; the vegetables will become watery and the texture will degrade. If the salad seems dry after a day in the fridge, stir in a tablespoon or two of extra vinaigrette or a splash of olive oil to recoat the pasta and restore moisture.
DishGrub Kitchen Tips
Trim prep time by chopping vegetables while the pasta cooks and cooling pasta under running cold water in a colander for faster chill. Use a shallow, wide bowl to toss everything; it helps ingredients coat evenly without smashing the veggies. If you’re short on time, swap rotini for store-bought cooked short pasta to skip the boiling step entirely. For a cozy side on a chilly evening, serve this salad at room temperature and pair it with a warm bowl of soup like our creamy cauliflower cheese soup for a satisfying combo that’s easy to pull together.
Make it your own
Turn this pasta salad into a protein-packed meal by adding cubed rotisserie chicken, cooked shrimp, or chickpeas. Swap the mayo for plain Greek yogurt to lighten the texture, or stir in a little pesto with the vinaigrette for herby depth. Add crumbled feta or shredded cheddar for a different flavor profile, or toss in chopped olives and capers for briny brightness. If you want more heat, fold in sliced pickled jalapeños or an extra 1/2 teaspoon of Cajun seasoning. For a Mediterranean twist, replace the Italian vinaigrette with lemon-oregano dressing and add chopped artichoke hearts and sun-dried tomatoes.
Frequently asked questions
How long will this pasta salad keep in the fridge?
This salad stays fresh for three to four days in an airtight container. The mayonnaise and vinaigrette both help preserve moisture, but the vegetables begin to soften after a few days. Keep it chilled until serving and do not freeze the salad because the texture will suffer.
Can I make this the day before a picnic?
Yes. In fact, letting the salad rest in the fridge for a few hours or overnight improves the flavor as the dressing penetrates the pasta. Pack it cold in an insulated cooler with an ice pack for transport. Bring a small extra container of vinaigrette to refresh the salad if it sits out for more than an hour.
What can I substitute for mayonnaise?
You can substitute plain Greek yogurt for a tangier, lighter version. If you prefer dairy-free, use a vegan mayo or increase the vinaigrette and add a tablespoon of tahini for body. Each swap slightly alters the mouthfeel, so taste and adjust the seasoning before chilling.
Can I use a different pasta shape?
Yes. Fusilli or penne work well because they catch the dressing and bits of vegetable. Choose short pasta that holds the dressing and matches the size of chopped vegetables for balanced bites.
My salad turned out watery. How do I prevent that?
Drain tomatoes well before adding them and remove cucumber seeds if they release a lot of liquid. Rinsing and cooling pasta thoroughly also helps; excess starchy water can make dressing thin. Add dressing gradually and chill the salad uncovered for a short while in the fridge to let excess moisture collect at the bottom, then stir and discard any watery separation if needed.
