A flavor-packed Pesto Pasta Salad with tomatoes, red onions, cucumbers, mozzarella, and toasted pine nuts. This delectable salad is the perfect summer salad for grilled chicken, fish, or steak. I love to make this with my homemade pesto sauce, but for speed and ease, store-bought will work as well.

We are always up for a good pasta salad, especially during the hot summer months, when a nice, cool one is always appreciated. This pasta salad, Italian Tortellini Pasta Salad, Tuna Pasta Salad, and Taco Pasta Salad are just a few of our favorites.
Ingredient Notes and Substitutions
See the complete list of ingredients on the recipe card below.
- Pasta: I like to use fusilli pasta, but other good choices are farfalle, penne, rotini, and corkscrew. Just make sure to cook it slightly al dente and to drain it very well.
- Tomatoes: Use any sun-ripened tomatoes, including grape, cherry, or garden or greenhouse varieties. Just chop in bite-sized pieces to complement the salad.
- English cucumbers: Use English cucumbers for tender skins that don’t need peeling. If using regular cucumbers, peel them to remove the thick skin before slicing.
- Mozzarella balls: Mozzarella balls are available in the fresh cheese case at most grocery stores. You can substitute cubes or even shredded mozzarella if that is all that is available.
- Pesto sauce: Use homemade or store-bought.
- Pine nuts: You can substitute walnuts, almonds, or cashews.

How to make Pesto Pasta Salad
This is a summary version; for the complete list of ingredients and instructions, please refer to the recipe card below.
- Start by cooking your pasta until slightly al dente, then drain well.
- In a large bowl, combine the pasta, tomatoes, red onions, mozzarella balls, cucumbers, and pesto sauce. Stir gently to combine.
- Toast the pine nuts in a dry skillet over medium heat for a few minutes, stirring frequently. Finally, sprinkle the toasted pine nuts on the top of the pasta salad.

Preparation Tips For Success
- Cook the pasta slightly al dente. Al dente means the pasta is slightly chewy and firm. This is always the best way to cook pasta for pasta salad.
- Fresh homemade pesto sauce is so flavorful. If you have the time and energy, it is well worth the effort.
- To make this the day before, only combine with half the pesto sauce, cover and refrigerate. Toss with the remaining pesto sauce right before serving.
