Pesto Chicken Mozzarella Pasta Salad Instructions

1. Cook and cool the pasta. Prepare the cavatappi according to package directions in well-salted water. Drain and rinse under cold water until completely cooled to room temperature. The curly shape of cavatappi is perfect for catching pesto in every nook—it’s like tiny flavor traps throughout the salad.
2. Prepare the chicken. If you haven’t already, dice your cooked chicken into bite-sized pieces. Rotisserie chicken is my secret for weeknight ease—just pull the meat and chop. In my testing, I found that slightly larger chicken pieces hold up better to tossing and refrigerating than tiny shreds.
3. Combine the base ingredients. Add the cooled pasta and diced chicken to a large mixing bowl. Toss them together gently to distribute the chicken evenly throughout the pasta.
4. Add the vegetables and cheese. Scatter in the mozzarella pearls, sliced cucumbers, halved tomatoes, and finely diced red onion. Each ingredient should be visible—the colors alone make this mozzarella pasta salad look like a celebration.
5. Dress with pesto and Parmesan. Pour the prepared pesto over everything and sprinkle in the shredded Parmesan. Using a large spoon or spatula, fold everything together gently until each piece glistens with that gorgeous green sauce. Be gentle with the mozzarella pearls—you want them whole, not smashed.
6. Garnish and serve. Transfer to a serving bowl or individual containers for meal prep. Scatter fresh basil leaves and extra Parmesan over the top. The basil leaves should look like little green confetti against the creamy white mozzarella and vibrant red tomatoes.

Substitutions & Variations

This summer meal prep champion adapts beautifully to what you have on hand. Any short pasta shape works—rotini, penne, farfalle, or shells all catch the pesto nicely. After making this dozens of times, my family’s favorite variation uses orecchiette for its little cup shape that pools pesto perfectly.

For a lighter version, use part-skim mozzarella or swap half the pasta for more vegetables. Cherry tomatoes, roasted red peppers, artichoke hearts, or sun-dried tomatoes all make delicious additions. Grilled zucchini adds a smoky depth that complements the basil beautifully.

Make it vegetarian by swapping the chicken for white beans or chickpeas—you’ll get similar protein with a different texture. For dairy-free, use vegan mozzarella and a dairy-free pesto. The flavors still shine through.

This pesto chicken pasta salad pairs wonderfully with a halloumi peach tomato salad for an impressive summer spread.

Expert Tips & Troubleshooting

Use refrigerated pesto, not jarred shelf-stable. The color and flavor difference is remarkable. Refrigerated pesto stays vibrant green while shelf-stable versions often turn muddy brown. According to Bon Appétit’s guide to buying pesto, refrigerated options also tend to have better texture and fresher basil flavor.

Cool pasta completely before dressing. Warm pasta absorbs too much pesto and can make the mozzarella sweat. Room temperature ingredients combine more evenly and maintain their distinct textures.

Salt your pasta water generously. The pasta is the base of this dish, and underseasoned noodles make the whole salad taste flat. Aim for water that tastes like the sea.

Don’t overdress. Start with half the pesto, toss, then add more as needed. You can always add more, but you can’t take it away. The salad also absorbs dressing as it sits, so it may need a refresh before serving.

Cut vegetables to match pasta size. Cucumber slices and tomato halves should be roughly the same size as the pasta curls for balanced bites every time.

Storage & Meal Prep

Component	Storage Method	Duration
Assembled salad	Airtight container, refrigerated	4 days
Cooked pasta (undressed)	Airtight container with olive oil drizzle	5 days
Diced chicken	Airtight container, refrigerated	4 days
Pesto	Original jar, refrigerated	Follow package date

This summer meal prep recipe was practically designed for batch cooking. Make the full recipe Sunday night and portion into individual containers for grab-and-go lunches all week. The flavors actually improve as everything marinates together.

If preparing ahead, store the basil garnish separately—it wilts quickly once added. Give the salad a good stir before serving and add a splash of olive oil if it seems dry. Fresh Parmesan on top right before eating brightens every bite.

Serving Suggestions

Serve this mozzarella pasta salad cold or at room temperature—both work beautifully. It’s substantial enough as a complete meal for lunch, or serve smaller portions as a side dish alongside grilled chicken, steak, or fish. The herby pesto complements smoky grilled proteins perfectly.

For a complete Italian-inspired spread, pair with crusty bread and a simple green salad. This pasta salad travels well for picnics and potlucks—it doesn’t need to stay cold during serving like mayo-based salads. Try it alongside a dense bean picnic salad for a protein-packed outdoor feast, or serve with a lemon Parmesan zucchini corn salad for summer vegetable abundance.
