Ingredients

For the basil pesto

  • 2 ½ cups fresh basil leaves
  • ½ cup Parmigiano Reggiano, grated, or Pecorino Romano, plus more for serving
  • ¼ cup pine nuts, toasted
  • 1 clove garlic, finely chopped
  • 1 tsp lemon zest, plus half a lemon juiced
  • 1 tsp Kosher salt
  • tsp freshly ground black pepper, plus more for serving
  • ½ cup extra virgin olive oil

For the pasta

  • 1 lb trenette pasta, can use spaghetti or linguine
  • ½ lb green beans, ends trimmed and cut into 1½-2 inch pieces
  • 1 large Russet potato, peeled and cut into 1-inch cubes
  • Extra virgin olive oil
  • Flaky sea salt

Instructions

  • Make the pesto sauce. Place all ingredients except for olive oil in the bowl of a food processor fitted with blade attachment: 2½ cups basil leaves, ½ cup grated Parmesan, ¼ cup toasted pine nuts, 1 clove chopped garlic, 1 tsp lemon zest, ½ lemon juiced, 1 tsp Kosher salt, and ⅛ tsp black pepper. Pulse until very finely chopped.
  • Finish with olive oil. With the machine on, slowly drizzle in ½ cup extra virgin olive oil until smooth and emulsified. Set aside or store in a fridge until needed.
  • Boil the water. Bring a large pot of water to a rapid boil, then season generously with 1-2 Tbsp Kosher salt.
  • Cook the potatoes. Carefully place the peeled cubed potato into the boiling water. Cook for about 3-4 minutes.
  • Add the pasta and string beans. Add pasta to the same large pot, then give it a good stir. Cook until al dente according to package instructions (usually 9-13 minutes, depending on the pasta). After 5 minutes, add the cut string beans. Check to make sure each ingredient is fully cooked, then reserve ½ cup of cooking water. Drain everything.
  • Toss with pesto sauce. To the same large pot, pour in the prepared pesto sauce. Place over medium heat, then add the drained pasta and veggies along with ½ cup of reserved pasta cooking water. Toss until heated through and the pasta is well coated, about 2 minutes.
  • Finish, then serve. Plate the pasta, sprinkle with additional Parmesan, then drizzle each portion with a little extra virgin olive oil, a pinch of flaky sea salt, and extra black pepper, if wanted. Serve immediately!

Notes

  • Basil pesto will keep for up to 5 days in a fridge.
