Preheat your oven to 425 degrees Fahrenheit.
Line a baking sheet with parchment paper to avoid sticking.
Cut broccoli into bite-sized florets.
Make sure the pieces are even in size for uniform cooking.
In a large bowl, combine the broccoli, olive oil, garlic, salt, and pepper.
Toss everything together until the broccoli is well coated.
Spread the broccoli evenly on the baking sheet.
Roast it in the oven for 15 minutes.
Remove the broccoli from the oven and sprinkle with Parmesan cheese.
Return it to the oven and bake for an additional 5-7 minutes until cheese melts and turns golden.
