Chop broccoli into evenly sized florets (about 2 inches).
In a large mixing bowl, combine the broccoli, oils, and seasonings. Toss well until evenly coated.
Spread the coated broccoli in a single layer on a large rimmed baking sheet. Roast at 400° for 15-20 minutes, tossing halfway through.
Remove from oven and garnish with sesame seeds and red pepper flakes. *You may also drizzle it with a small amount of additional sesame oil if you desire.
