Spaghetti with Broccolini Pesto

Put a large saucepan of water on to boil. Separate broccolini florets and stems. Cook the stems in the boiling water for 1 minute. Using a slotted spoon, transfer to a food processor.

Cook pasta in the boiling water according to package directions. Add the florets during the last minute of cooking. Drain the pasta and florets and return to the pot.

Meanwhile, add basil, Parmesan, lemon zest and juice, garlic, salt and pepper to the food processor. Pulse, scraping down the sides a few times, until mostly pureed. Drizzle in oil and puree until smooth.

Add the pesto and edamame to the pasta mixture and gently toss to combine. Place over medium heat and gently stir until hot, 1 to 2 minutes. Serve with more Parmesan, if desired.
