Creating Roasted Potatoes and Broccoli with Parmesan is straightforward. Follow these steps for a guaranteed success:

1. Preheat Oven: Preheat your oven to 425°F (220°C). A hot oven is essential to achieve that crispy texture.

1. Prepare Ingredients: Wash and dice the potatoes into even-sized cubes. Rinse the broccoli florets under cold water and drain them well.

1. Mix Vegetables: In a large bowl, combine the diced potatoes and broccoli florets.

1. Season: Drizzle the olive oil over the vegetables, and sprinkle the garlic powder, onion powder, paprika, salt, and pepper. Mix well to fully coat the vegetables in the seasoning.

1. Spread on Baking Tray: Line a baking sheet with parchment paper. Spread the seasoned potatoes and broccoli evenly on the sheet. Make sure they are in a single layer for even roasting.

1. Roast: Place the baking sheet in the preheated oven. Roast for about 20-25 minutes. Stir halfway through for even cooking.

1. Add Parmesan: After 20-25 minutes, remove from the oven and sprinkle the grated Parmesan cheese over the vegetables. Return to the oven for an additional 5-10 minutes, or until the cheese is golden and crispy.

1. Garnish: Once roasted to perfection, take the dish out of the oven. Garnish with chopped parsley to add a touch of freshness.

1. Serve: Transfer the roasted veggies to a serving dish. They are now ready to be enjoyed!
