Trenette al pesto

Makes 4–6 Servings



  • Kosher salt, as needed
  • 1 lb trenette, bavette, or linguine
  • 1 cup diced potatoes
  • 1 1/2 cups trimmed green beans, cut into 1-inch lengths
  • 1 cup Pesto or as needed
  • Toasted pine nuts, for garnish (optional)


  1. Bring a large pot of salted water to a rolling boil; covering the pot will help it come to a boil more quickly.
  2. Add the trenette all at once and stir a few times to separate the pasta. Add the potatoes and green beans 2 minutes after adding the pasta. Cook uncovered at a boil until the pasta and the potatoes are just tender to the bite, 10 to 12 minutes.
  3. Transfer a few ladlefuls of pasta water from the pot to a bowl or cup to have ready for finishing the sauce. (You may need up to 1/2 cup.)
  4. Drain the pasta and vegetables immediately through a colander. Shake well to remove any water clinging to the pasta. Pour the drained pasta and vegetables into a large serving bowl.
  5. Add the pesto to the trenette and toss together until the pasta is evenly coated. The pesto should appear creamy, not oily. If necessary, add a bit of the reserved pasta water.
  6. Garnish the dish with a few toasted pine nuts if desired. Serve at once.
