The first time I ever made a Pesto Pasta Salad with store bought pesto, I thought, really? This is it? I was underwhelmed and disappointed because I was looking forward to luscious pesto coating hot, long strands of pasta. The pasta was too firm, (even though I cooked the pasta to al dente,) with only a hint of basil, and it just tasted flat. This recipe for Pesto Pasta Salad with Roasted Tomatoes is not altogether different from that first attempt, but it tastes worlds apart. THIS pesto salad is a glorious celebration of summer, and the difference is all in the details. I made my own pesto sauce (instead of store-bought) using fresh basil. I toasted the pine nuts to bring out their nutty flavor. Beautiful summer cherry tomatoes were roasted to make them taste like candied tomatoes, without adding any sugar. I made sure to check the seasoning and add more salt before serving, to keep the flavors tasting bright and savory. Milky fresh mozzarella provided nuggets of soft, creamy flavor and texture. Each pesto-infused bite of pasta was a revelation in my mouth, with big, bold basil flavor. I was very, very happy.

Notes: I beg you to try making your own pesto at least once, (as in this recipe,) before deciding to use the store-bought kind. I have definitely used store-bought before for convenience, but when I developed this recipe, I did a side-by-side comparison of freshly made pesto vs. the store-bought pesto, and the fresh pesto blew my mind. Really. The difference was huge, and if you have a food processor or blender, fresh pesto only takes a few minutes to make. 

I have been overcooking my pasta for pasta salad by a minute or two ever since I read this post on Serious Eats about how pasta gets stiffer when it cools, so over-cooking the pasta a bit for pasta salad is great because it keeps the texture from getting too firm.

Pine nuts are at least half of what makes pesto so darn good, but I realize they are pricey. You can substitute half or all of the pine nuts for walnuts, and it will be a suitable substitution.

This Pesto Pasta Salad alongside Cynthia's Mediterranean Turkey Burgers and Mustardy Potato Salad makes an amazing barbecue. Adding shredded or diced chicken would also make this the perfect light summer meal, rather than a side.




Time: 45 minutes
Servings: 8-10

1 pound cherry tomatoes
1 tablespoon plus 1 cup extra virgin olive oil, divided use
Kosher salt
Freshly ground black pepper
1 cup pine nuts, divided use
1 pound farfalle (bow tie) pasta
1 cup parmesan cheese, grated
4 cups basil leaves, packed (about 5 ounces)
4 cloves garlic, roughly chopped
1/2 cup parsley, finely chopped
1 cup green onions, thinly sliced
pound fresh mozzarella, cut (or torn) into 1-inch piece

Preheat oven to 400 degrees F. Combine cherry tomatoes and 1 tablespoon olive oil on a rimmed sheet pan. Sprinkle lightly with salt and pepper. Roast tomatoes for 20-25 minutes, until tomatoes are soft and releasing some of its juice. Let cool.

Reduce oven temperature to 375 degrees F. Place pine nuts on a rimmed sheet pan, and toast in oven until golden brown, about 5 minutes. Let cool.

Meanwhile, bring a large pot of salted water to boil. Stir in pasta, and adjust heat to maintain a low boil. Cook for two minutes longer than the package instructions. Drain and rinse pasta in cold water until the pasta is no longer warm.

Make pesto: Combine 1/2 cup toasted pine nuts, parmesan, basil leaves, and garlic in a food processor or blender. Process until a paste is formed, stopping to scrape the container down as needed. With the motor running, drizzle in 1 cup olive oil, and process until the oil is fully incorporated and pesto is smooth.

In a large mixing bowl, combine pasta, pesto, chopped parsley, sliced green onions, and remaining toasted pine nuts until pasta is evenly coated. Add half of the roasted tomatoes and half the mozzarella and toss to combine. Taste and adjust seasoning with additional salt and freshly ground pepper. Pour pasta salad into a large serving bowl, and arrange the remaining tomatoes and mozzarella on top. Serve at room temperature.
