Pesto Pea Ditalini Salad

This Pesto Pea Ditalini Salad became a staple in my kitchen the summer I needed something quick for a Labor Day picnic.

Tiny tubes of pasta, sweet peas, and creamy mozzarella pearls all get tossed in a zesty basil pesto that clings to every bite. Seriously, who doesn’t love a pasta salad that comes together in under thirty minutes?

The bright green pesto against the pop of red cherry tomatoes makes this dish look as good as it tastes. It’s got that creamy, herby aroma that fills the kitchen the moment you whisk the dressing together. In my testing, I found the mozzarella pearls are what make people go back for a second scoop.

Ingredients

Category	Ingredient	Amount	Notes
Pasta Base	Ditalini pasta	12 oz	Small shells work as a substitute
Pasta Base	Frozen peas, thawed	1½ cups	Fresh peas work when in season
Pasta Base	Cherry tomatoes, halved	1 cup	Grape tomatoes are a good swap
Pasta Base	Fresh mozzarella pearls	1 cup	Cubed mozzarella works too
Pasta Base	Fresh basil, chopped	¼ cup	Adds a fresh herbal note
Pasta Base	Parmesan cheese, grated	¼ cup	Use fresh-grated for best melt and flavor
Dressing	Pesto	½ cup	Store-bought or homemade both work
Dressing	Mayonnaise	¼ cup	Greek yogurt is a lighter substitute
Dressing	Fresh lemon juice	2 tbsp	Freshly squeezed brightens the flavor
Dressing	Salt	½ tsp	Adjust to taste
Dressing	Black pepper	¼ tsp	Freshly cracked preferred

Instructions

Step 1: Cook the pasta. Cook the ditalini pasta according to the package directions until al dente. Drain, rinse under cold water, and let cool completely so it doesn’t wilt the other ingredients.

Step 2: Combine the base. In a large bowl, combine the cooled pasta, peas, cherry tomatoes, mozzarella pearls, fresh basil, and Parmesan cheese. The little peas nestle into the pasta tubes almost like they were made for each other, which is exactly the original comparison that sold me on this combo.

Step 3: Whisk the dressing. In a small bowl, whisk together the pesto, mayonnaise, lemon juice, salt, and black pepper. The dressing should turn a vibrant green with a smooth, creamy texture and a fresh basil aroma.

Step 4: Toss everything together. Pour the pesto dressing over the pasta mixture and gently toss until everything is evenly coated. After making this dozens of times, I’ve found folding gently with a rubber spatula keeps the mozzarella pearls intact.

Step 5: Chill. Refrigerate for at least 30 minutes to allow the flavors to meld. The pasta soaks up the pesto flavor and the tomatoes release a little juice that makes everything taste even fresher.

Step 6: Serve. Stir gently before serving and garnish with additional Parmesan or basil if desired. Serve chilled or at room temperature for the best texture and flavor.

Substitutions and Variations

Need a lighter version of this pesto pea salad? Swap the mayonnaise for plain Greek yogurt to cut the richness while keeping the creamy texture.

For a vegan pea ditalini salad, use a dairy-free pesto and swap the mozzarella pearls for marinated white beans or diced avocado.

My family’s favorite variation adds grilled chicken or crispy pancetta for extra protein when we’re serving it as a main dish instead of a side.

Expert Tips and Troubleshooting

Watery pasta salad is one of the most common complaints I hear. In my testing, rinsing the pasta under cold water and letting it drain fully before mixing prevents excess liquid from pooling at the bottom of the bowl.

If your dressing tastes bland, add an extra squeeze of lemon juice or a pinch more salt right before serving. Flavors mellow after chilling, so always taste and adjust before you plate it.

Storage and Meal Prep

Component	Storage Method	Duration
Assembled Salad	Airtight container, refrigerated	Up to 3 days
Pesto Dressing	Sealed jar, refrigerated	Up to 5 days
Cooked Pasta	Airtight container, refrigerated	Up to 3 days
Chopped Vegetables	Separate containers, refrigerated	Up to 3 days

For the best meal prep results, store the dressing separately and toss it in right before serving. This keeps the pasta from soaking up too much liquid and turning mushy.
