  2. Step 2: In a small bowl, whisk together 3 tbsp freshly squeezed lemon juice, 2 minced garlic cloves, 1/2 tsp smoked paprika, 1/4 tsp ground cumin, 1 tsp salt, and 1/2 tsp black pepper until combined.
  3. Step 3: Drizzle the lemon garlic mixture over the cauliflower florets and toss gently with your hands or tongs to coat all pieces evenly.
  4. Step 4: Roast the cauliflower in the preheated oven for 25-30 minutes, stirring halfway through, until the edges are golden and tender.
  5. Step 5: Remove from the oven and sprinkle 2 tbsp chopped fresh parsley over the top before serving warm.
