Trim the tough base off the broccoli stems, then cut 1 pound fresh broccoli into florets. Cut any longer stem pieces into coins.
Drizzle 1-2 tablespoons extra virgin olive oil over the broccoli, and toss to coat evenly. Sprinkle with ½ teaspoon garlic salt and Freshly ground black pepper.
Spread the broccoli in a single layer on a baking sheet and bake in the preheated oven for 16-21 minutes.
Remove the broccoli from the oven, sprinkle with ¼ cup shredded Parmesan cheese, and return the pan to the oven. Cook for 3-4 minutes, or until the broccoli is fork-tender and the edges are caramelized.
