Preheat the oven to 375F and line a large sheet pan with parchment paper.
In a large bowl, combine the broccolini with the oil, garlic, and parmesan cheese. Stir well with your clean hands to evenly coat the broccolini pieces.
Transfer to your prepared pan and arrange in a single layer. Top with the remaining parmesan that's left at the bottom of the bowl.
Season with salt and pepper to your taste.
Bake for 12-15 minutes, or until tender with a crisp.
Serve with lemon wedges, if desired.
Notes
Can't get a hold of broccolini? Use broccoli.
Don't like Broccoli? Use any other vegetable like cauliflower. If using cauliflower, you will need to roast longer. Roast for an additional 10-15 minutes until crispy and tender.
Use fresh garlic if possible. You may use garlic powder if you must.
Rice and clean the Broccolini before adding to the pan. Cut out the tough bottom edges if needed.
