Preheat the oven to 400°F.

Line a large baking sheet with parchment paper.

Make sure the broccoli florets are roughly 1 inch wide, and arrange them in an even layer on the baking sheet.

Drizzle the broccoli with olive oil. Sprinkle with salt and black pepper.

Use a rubber spatula to toss the broccoli until it is evenly coated in the oil.

Roast broccoli on middle rack of oven for 15 minutes. While it is roasting, finely mince the garlic cloves.

Open the oven and sprinkle the garlic over the broccoli. Toss lightly with a rubber spatula to distribute the garlic. Continue roasting until garlic is fragrant and broccoli is crisp-tender, 8-10 minutes.

Check to see that broccoli is done. Remove from oven or add time as needed.

Serve immediately.
