Preheat your oven to 400°F (205°C) and line a baking sheet with parchment paper.
Carefully remove the leaves from the cauliflower and trim the stem to create a flat base, ensuring the head remains intact.
In a small bowl, mix together the olive oil, sea salt, black pepper, garlic powder, and smoked paprika.
Place the cauliflower head on the prepared baking sheet and generously brush the entire surface with the seasoned oil mixture.
Roast in the preheated oven for 1 hour, or until the surface is golden brown and a knife inserts easily into the core.
While the cauliflower is roasting, prepare the whipped goat cheese by combining the goat cheese, heavy cream, and lemon juice in a food processor. Blend until the mixture is smooth and airy. Season with salt and pepper to taste.
Once the cauliflower is done, let it rest for a few minutes before transferring it to a serving plate.
Top the cauliflower with dollops of whipped goat cheese, a sprinkle of chopped parsley, and lemon zest for a burst of freshness.
Serve immediately while warm, slicing into wedges and ensuring each portion has a generous helping of whipped goat cheese.
