Preheat the oven to 425°F (220°C). Line a large baking sheet with parchment paper for easier cleanup.
In a large mixing bowl, combine the cauliflower florets with olive oil, minced garlic, chopped rosemary, thyme leaves, smoked paprika, salt, and pepper. Toss well to ensure all florets are evenly coated.
Spread the seasoned cauliflower in a single layer on the prepared baking sheet.
Roast in the preheated oven for 25-30 minutes, or until the florets are golden brown and tender, stirring halfway through for even cooking.
Remove from the oven and drizzle the lemon juice over the roasted cauliflower. Add lemon zest and give it a gentle toss to combine.
Garnish with chopped parsley before serving.
Notes
For extra flavor, add more herbs or spices as desired.
