Step 1: Prepare the Cauliflower

1. Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper or lightly grease it with cooking spray.
2. Wash and dry the cauliflower thoroughly. Remove the leaves and core, then cut the cauliflower into bite-sized florets.

Step 2: Season the Cauliflower

1. In a large mixing bowl, combine the olive oil, minced garlic, Italian seasoning, smoked paprika, salt, and black pepper.
2. Add the cauliflower florets to the bowl and toss until they are evenly coated with the seasoning mixture.

Step 3: Roast the Cauliflower

1. Spread the seasoned cauliflower in a single layer on the prepared baking sheet. Ensure the florets are not overcrowded to allow even roasting.
2. Roast in the preheated oven for 20-25 minutes, flipping the florets halfway through to ensure even browning.

Step 4: Add the Parmesan Cheese

1. Remove the baking sheet from the oven and sprinkle the grated Parmesan cheese evenly over the roasted cauliflower.
2. Return the cauliflower to the oven and roast for an additional 5 minutes, or until the cheese is melted and golden.

Step 5: Garnish and Serve

1. Transfer the roasted cauliflower to a serving platter and garnish with freshly chopped parsley.
2. Serve immediately as a side dish or enjoy it as a light, healthy snack.
