Why You’ll Love This Chicken Pasta Salad

This recipe is simple, flexible, and packed with fresh ingredients. Rotini works especially well because its twists catch the olive oil and herb dressing in every bite.

The combination of grilled chicken, cherry tomatoes, cucumber, red onion, mozzarella, and Kalamata olives creates a balanced mix of savory, tangy, creamy, and fresh flavors. Fresh parsley or basil adds a final burst of flavor.

You can serve it chilled or let it sit at room temperature for a short time before serving. It also works well as a main dish because it combines protein, carbohydrates, vegetables, and healthy fats in one bowl.

Ingredients You’ll Need

For the Salad

12 ounces rotini or fusilli pasta
2 boneless, skinless chicken breasts
1 cup cherry tomatoes, halved
1 English cucumber, diced
½ red onion, thinly sliced
8 ounces fresh mozzarella pearls or cubed mozzarella
½ cup Kalamata olives, sliced
Fresh parsley or basil, chopped
Salt and black pepper, to taste
1 teaspoon Italian seasoning
Olive oil for seasoning the chicken

For the Herb Vinaigrette

½ cup extra virgin olive oil
3 tablespoons red wine vinegar or fresh lemon juice
1–2 garlic cloves, minced
1 teaspoon dried oregano
1 teaspoon dried basil
Salt and black pepper, to taste
1 teaspoon Dijon mustard, optional
A small pinch of sugar, optional

How to Make Fresh Grilled Chicken Pasta Salad

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Add the rotini and cook according to the package directions until al dente.

Drain the pasta and rinse it lightly under cold water to stop the cooking process. Let it drain well and cool completely before assembling the salad.

Step 2: Season the Chicken

Pat the chicken breasts dry with paper towels. Brush them lightly with olive oil, then season both sides with salt, black pepper, and Italian seasoning.

For more even cooking, gently pound thick areas of the chicken so both breasts have a similar thickness.

Step 3: Grill the Chicken

Preheat a grill pan or outdoor grill over medium heat. Place the seasoned chicken on the hot surface and cook for about 5–7 minutes per side, depending on thickness.

Cook until the chicken reaches a safe internal temperature of 165°F. Remove it from the heat and let it rest for 5 minutes before slicing.

Step 4: Prepare the Vegetables

While the chicken rests, halve the cherry tomatoes and dice the cucumber into bite-sized pieces.

Thinly slice the red onion and olives. Chop the fresh parsley or basil, keeping some herbs aside for the final garnish.

Step 5: Make the Herb Dressing

Add extra virgin olive oil, red wine vinegar or lemon juice, minced garlic, oregano, basil, salt, and black pepper to a small bowl.

Whisk until the dressing looks evenly blended. Add Dijon mustard for extra flavor or a tiny pinch of sugar if you prefer a softer, more balanced acidity.

Step 6: Slice the Chicken

After the chicken has rested, slice it into thin strips or bite-sized pieces.

Allowing the meat to rest before cutting helps retain its juices, so the chicken stays tender when mixed with the pasta.

Step 7: Build the Salad

Add the cooled pasta, tomatoes, cucumber, red onion, and olives to a large mixing bowl.

Add the sliced grilled chicken and mozzarella. Toss the ingredients gently so the cheese stays intact and the vegetables remain crisp.

Step 8: Add the Dressing

Pour the herb vinaigrette over the salad gradually. Toss gently until the pasta, chicken, vegetables, and cheese are evenly coated.

You may not need every drop of dressing, so add it slowly and adjust according to your preferred texture.

Step 9: Chill and Serve

Cover the bowl and refrigerate the salad for 10–15 minutes before serving. This short chilling time allows the herbs, vegetables, chicken, and dressing to blend together.

Finish with fresh parsley or basil just before serving. Serve chilled or at room temperature.

Tips for the Best Results

Cook the pasta only until al dente so it stays firm after chilling.
Cool the pasta completely before adding fresh vegetables and cheese.
Avoid over-rinsing the pasta because excessive rinsing can remove flavor.
Let grilled chicken rest before slicing to keep the meat juicy.
Cut vegetables into similar sizes for a better texture in every bite.
Add the dressing gradually so the salad does not become soggy.
Use fresh mozzarella for a softer, creamier texture.
Add fresh herbs close to serving time for the best flavor.
Reserve a little dressing if you plan to eat the salad later.
Use a good-quality extra virgin olive oil because it forms the base of the vinaigrette.

Easy Variations

This pasta salad is easy to change based on your preferences. Replace the grilled chicken with grilled shrimp or cooked turkey for a different protein option.

For extra vegetables, add diced bell peppers, roasted zucchini, spinach, or arugula. Chickpeas can add plant-based protein, while avocado provides extra creaminess.

If you prefer a sharper cheese, swap mozzarella for crumbled feta. You can also replace the vinaigrette with pesto for a richer herb flavor.

For more heat, add crushed red pepper flakes or finely chopped jalapeños. Sun-dried tomatoes can also provide a deeper, slightly sweet flavor.

Make-Ahead and Storage

This chicken pasta salad is a convenient make-ahead meal. Prepare the pasta, chicken, vegetables, and dressing separately if you want the freshest texture.

Store leftovers in an airtight container in the refrigerator and use them within 3 days. If the salad looks dry after chilling, add a small amount of reserved dressing before serving.

Freezing is not recommended because cucumber, tomatoes, fresh herbs, and mozzarella can lose their texture after thawing.
