Step 1

Bring a medium pot of water to boil and place a bowl of ice water nearby. Blanch the broccoli in the boiling water for 30 seconds, and then use a slotted spoon to scoop it into the ice water to stop the cooking process. Drain and pat dry.

Step 2

Place the broccoli into a food processor with the basil, olive oil, cheese, lemon juice and zest, garlic, salt, and several grinds of fresh pepper. Pulse until combined.

Step 3

If desired, toss the pesto with the cooked pasta. Serve with pine nuts, red pepper flakes, and additional cheese. Season to taste and serve.
