Preheat oven to 400 degrees and heat a pot of water (on high) for the pasta.
Trim the stems of the broccolini (I cut off about an inch) and put in a roasting pan with the chopped garlic. Toss with 2 tbsp olive oil, the crushed red pepper, and the juice from half the lemon. Roast for 8-10 minutes.
While broccolini is roasting, cook pasta according to package directions. Drain, then add 2 tbsp olive oil, the juice from the other half of the lemon, and salt.
Divide the pasta onto plates and top with broccolini.
