Pesto Pasta Salad is the perfect summer side dish, made with gluten free rotini pasta tossed with a homemade spinach pesto sauce, mozzarella, and cherry tomatoes, ready in under 30 minutes!
Fill a large pot with water and bring it to a boil. Add about 2 teaspoons of salt to the water. Cook the pasta according to package directions until al dente. Drain and rinse the pasta in cold water to stop it from cooking further.
Add all of the pesto ingredients to a food processor. Pulse the food processor a few times, then while the food processor is running add any extra olive oil or lemon juice as-needed to make everything blend smoothly.
Add the pasta to a large mixing bowl, then gently stir together with the pesto, tomatoes, arugula, and mozzarella balls. Add any additional salt or black pepper as-needed, then refrigerate until ready to serve.

StorageRefrigerate leftovers in an airtight container for 3-4 days.Cooking Tips
Be careful not to overcook the pasta! Just cook it to al dente, then rinse with cold water. If not, the pasta will be falling apart.
Taste the pesto before pouring it into the mixing bowl. You can adjust with salt, pepper, olive oil, or lemon juice as-needed until you get the right flavor and texture.
You'll get the best flavor if you bring it to room temperature before serving. Give it 15-20 minutes.
Salting the pasta water adds another layer of flavor as it cooks. Most of the salt stays in the water when you drain it.
Wait until the pasta has cooled before adding the other ingredients, so the mozzarella doesn't start melting.
