Equipment

  • Large pot For boiling pasta and blanching broccoli
  • Food processor Or high-speed blender
  • Colander Or slotted spoon for draining broccoli
  • Large mixing bowl Or serving bowl for tossing pasta
  • Large skillet or sauté pan (optional) For tossing pasta with sauce
  • Tongs or pasta spoon For tossing and serving
  • Zester or fine grater For lemon zest and Parmesan
  • Measuring cups and spoons
  • Small baking sheet or skillet For toasting pine nuts

Ingredients
  

  • 12 oz pasta 340g; spaghetti, linguine, penne, or rigatoni all work well
  • 3 cups broccoli florets about 300g, cut into roughly equal pieces
  • 1 cup fresh basil leaves about 25g, packed
  • 2 garlic cloves peeled
  • 1/3 cup grated Parmesan cheese about 30g, freshly grated; plus more for serving
  • 1/4 cup pine nuts about 35g, lightly toasted
  • 1/2 cup extra virgin olive oil 120ml; plus more for drizzling
  • 2 tbsp fresh lemon juice about 1/2 lemon
  • 1/2 tsp lemon zest
  • 1/2 tsp salt plus more for pasta water
  • 1/4 tsp black pepper
  • 1/4 tsp red pepper flakes optional, for heat
  • 2 tbsp reserved pasta cooking water up to 4 tbsp; to loosen the sauce as needed

For Serving

Instructions
 

  • Add pine nuts to a dry skillet over medium-low heat and stir frequently for 2 to 3 minutes until lightly golden and fragrant. Immediately transfer to a plate to cool.
  • Fill a large pot with 4 to 5 quarts of water and bring to a rolling boil over high heat. Add 1 to 2 tablespoons of salt — the water should taste pleasantly salty.
  • Add broccoli florets to the boiling water and blanch for 2 to 3 minutes until bright green and just tender. Remove with a slotted spoon and set aside to cool for 5 minutes — do not drain the pot.
  • Return the water to a boil, add the pasta, and cook according to package instructions until al dente. Before draining, scoop out at least 1/2 cup of pasta cooking water, then drain the pasta without rinsing.
  • Add the cooled broccoli, basil, garlic, toasted pine nuts, Parmesan, lemon juice, lemon zest, salt, pepper, and red pepper flakes to a food processor. Pulse to combine, then stream in the olive oil while processing until smooth and creamy, about 30 to 45 seconds.
  • Add all of the broccoli pesto to the drained pasta and toss to coat. Add reserved pasta water a tablespoon at a time, tossing until the sauce is glossy and coats the pasta evenly.
  • Divide pasta into bowls and top with a drizzle of olive oil, extra Parmesan, a few pine nuts, and a pinch of red pepper flakes. Serve immediately.

Notes

  • Don't overcook the broccoli: Blanch for no more than 2 to 3 minutes to keep the pesto bright green and fresh-tasting.
  • Cool before blending: Let blanched broccoli cool for 5 minutes before processing — blending hot vegetables can cause steam buildup and dull the color.
  • Salt your pasta water generously: The water should taste like mild seawater. This seasons the pasta from the inside and is the most impactful flavoring step.
  • Always save pasta water: The starchy cooking water emulsifies the sauce and helps it cling to the pasta. Don't skip this step.
  • Vegan option: Replace Parmesan with 3 tablespoons of nutritional yeast and add an extra squeeze of lemon juice for brightness.
  • Nut-free option: Omit pine nuts or substitute with toasted sunflower seeds or pumpkin seeds.
  • Make ahead: The broccoli pesto can be stored in the refrigerator for up to 5 days. Press plastic wrap against the surface or drizzle a thin layer of olive oil on top to prevent browning.
  • Freezing the pesto: Freeze pesto in an ice cube tray for up to 3 months. Do not freeze the assembled pasta as the texture suffers significantly.
  • Reheating: Reheat pasta in a skillet over medium-low heat with a splash of water or olive oil, tossing gently for 3 to 4 minutes. Alternatively, microwave with 1 to 2 tablespoons of water in 30-second bursts.
  • Nut substitutions: Toasted walnuts, cashews, or slivered almonds can all replace pine nuts for a slightly different flavor profile.
