  • 1 head cauliflower cut into florets (about 8 cups)
  • 1 lemon juiced and zested
  • 2 tablespoon olive oil
  • 4 cloves garlic minced
  • 3 teaspoons fresh parsley chopped, divided
  • 1/2 teaspoon sea salt
  • 1/4 teaspoon black pepper
  • 1/2 cup Parmesan cheese shaved or grated
  • Crushed red pepper flakes for garnish


  • Preheat oven to 425 degrees F. Line a large baking sheet with aluminum foil or parchment paper; set aside.
  • Place cauliflower florets in a large bowl. In a separate small bowl, whisk together lemon juice, olive oil, garlic, and 1 1/2 teaspoons chopped parsley. Drizzle the oil blend over the cauliflower and toss to coat.
  • Spread florets out in a single layer on the baking sheet. Sprinkle with salt and pepper to taste.
  • Roast for 35-40 minutes, stirring cauliflower and rotating the pan halfway through bake time, until tender and golden, with some bits starting to caramelize.
  • Sprinkle parmesan over cauliflower and return to oven for 5 additional minutes until cheese has melted. Remove from the oven and allow to cool for 3-4 minutes before transferring to a serving dish. 
  • Garnish with lemon zest, fresh parsley, and red pepper flakes as desired.
