Preheat the oven to 375 degrees f.
In a large bowl add broccoli florets, then sprinkle with garlic powder, oregano, sea salt and pepper and oil.
Using your hands gently toss to coat really well.
Place the broccoli on a large rimmed baking sheet or use two sheets if necessary.
Arrange in a single layer making sure the pieces are not overly crowded.
Bake in your preheated oven for 15-20 minutes until the broccoli is tender and golden brown/crispy on the sides.
Remove from the oven and immediately stir in the Parmesan cheese.
