Ingredients
- 225 grams rotini or fusilli pasta (8 oz)
- 30 milliliters Cajun seasoning (2 tbsp), ensure it's a quality blend of smoked paprika, cayenne, garlic powder, onion powder, and oregano
- 120 milliliters mayonnaise (1/2 cup), full-fat recommended for creaminess
- 30 milliliters fresh lemon juice (2 tbsp), essential for brightness
- 1 medium green bell pepper, finely diced
- 3 green onions (scallions), thinly sliced
- 2 stalks celery, finely chopped
- 240 grams cherry tomatoes (1 cup), halved
- 60 milliliters fresh parsley (1/4 cup), finely chopped
- 30 milliliters olive oil (2 tbsp), extra virgin for best flavor
- Sea salt and freshly ground black pepper, to taste
- Optional: 150 grams cooked shrimp or grilled chicken (1 cup), diced or shredded, for added protein
Instructions
- Bring a large pot of generously salted water to a rolling boil. Add the rotini or fusilli pasta and cook according to package directions until it reaches a perfect al dente texture, typically 8-10 minutes. Al dente ensures the pasta holds up well in the salad and doesn't become mushy. Once cooked, drain the pasta thoroughly and immediately rinse it under cold running water to halt the cooking process and cool it down rapidly. This prevents sticking and ensures a pleasant texture in a cold salad. Drain very well.
- While the pasta is cooking, prepare your vegetables. Finely dice the green bell pepper, thinly slice the green onions, and finely chop the celery stalks. Halve the cherry tomatoes. Take your time to ensure even cuts, as this contributes to the salad's aesthetic appeal and ensures a consistent texture in every bite. Finely chop the fresh parsley.
- In a large mixing bowl, combine the mayonnaise, olive oil, fresh lemon juice, Cajun seasoning, a pinch of sea salt, and a generous grind of black pepper. Whisk vigorously until the dressing is smooth and well emulsified. Taste the dressing and adjust the seasoning as needed; you might want more Cajun spice for an extra kick, or a little more lemon juice for brightness.
- Add the thoroughly cooled and drained pasta, along with all the prepared chopped vegetables (green bell pepper, green onions, celery, and halved cherry tomatoes) to the bowl with the dressing. Gently fold all the ingredients together using a spatula or large spoon. Be careful not to crush the pasta or tomatoes. Ensure that the pasta and vegetables are evenly coated with the flavorful Cajun dressing.
- Gently fold in the finely chopped fresh parsley. If you are opting to add protein, such as cooked shrimp or grilled chicken, incorporate it into the salad at this stage. Ensure it is evenly distributed throughout.
- Cover the mixing bowl tightly with plastic wrap or transfer the salad to an airtight container. Refrigerate the pasta salad for at least 30 minutes before serving. This chilling period is crucial as it allows the flavors to meld beautifully and intensify, resulting in a much more delicious and cohesive dish. For optimal taste, chilling for 2-4 hours is recommended.

Essential Success Tips
- Do not overcook the pasta; al dente pasta holds its shape better and provides a pleasant chew in a cold salad.
- Rinse the cooked pasta thoroughly under cold water to remove excess starch and prevent it from sticking together.
- Allow the salad to chill for at least 30 minutes, or preferably longer, before serving. This allows the flavors to marry and deepen.
- Taste the dressing before adding the pasta and vegetables, and adjust the Cajun seasoning, salt, or lemon juice to your preference.
- Use fresh, high-quality ingredients, especially for the vegetables and herbs, to ensure the best flavor and texture.
Professional Cooking Secrets
- For an even deeper flavor profile, gently toast your Cajun seasoning in a dry pan for 30 seconds before adding it to the dressing. This awakens the spices' aromatic oils.
- Consider adding a teaspoon of apple cider vinegar or white wine vinegar to the dressing along with the lemon juice. The acidity will further brighten the flavors and cut through the richness of the mayonnaise.
- If using chicken, consider marinating it briefly in a small amount of Cajun seasoning and olive oil before grilling or cooking to infuse it with extra flavor.

Notes
- Storage: This pasta salad can be stored in an airtight container in the refrigerator for up to 3-4 days. The flavors often improve on the second day.
- Variations: Feel free to add other vegetables like corn, black beans, or finely diced red onion. For a dairy-free version, use a plant-based mayonnaise.
- Spice Level: The spice level can be adjusted by adding more or less cayenne pepper to your Cajun seasoning blend, or by incorporating a few dashes of hot sauce into the dressing.
Frequently Asked Questions
Can I make this pasta salad ahead of time?
Absolutely! This pasta salad is an excellent make-ahead dish. Preparing it a few hours or even a day in advance allows the flavors to fully meld, resulting in an even more delicious and cohesive taste.
How spicy is this dish?
The spice level can be customized. Using a standard Cajun seasoning blend will provide a moderate kick. If you prefer it milder, use less seasoning. For extra heat, add a pinch more cayenne pepper or a few drops of your favorite hot sauce to the dressing.
Can I use a different type of pasta?
Yes, you can! While rotini or fusilli are excellent for trapping the dressing, other short, sturdy pasta shapes like penne, farfalle (bow-tie), or elbow macaroni would also work well. Choose a pasta shape that holds up to mixing and coating.
