Ingredients

  • For the Roasted Cauliflower:
  • 1 medium head cauliflower cut into evenly sized florets approximately 4–5 cups
  • 1 tablespoon extra virgin olive oil
  • ½ teaspoon salt or to taste
  • Black pepper freshly ground to taste
  • For the Lemon Herb Sauce:
  • 2 green onions scallions roughly chopped
  • 1 bunch fresh flat-leaf parsley approximately 1 cup loosely packed
  • ½ teaspoon salt
  • 2 slices fresh green chili serrano or jalapeño — add more slices for extra heat
  • Zest from 1 large lemon
  • Juice from half a lemon approximately 1.5–2 tablespoons
  • 3 tablespoons extra virgin olive oil

Instructions

  • Preheat oven to 410°F (210°C) and allow to fully preheat before cauliflower goes in — full preheat is essential for caramelization.
  • Cut cauliflower into evenly sized florets approximately 1.5–2 inches across for consistent roasting.
  • Place florets in a large bowl, drizzle with 1 tablespoon extra virgin olive oil, add salt and freshly ground black pepper, and toss well until every floret is evenly coated — use hands for most thorough coating.
  • Line a large baking sheet with parchment paper and spread seasoned florets in a single even layer with space between each piece — do not overcrowd.
  • Roast on center rack at 410°F for 20–25 minutes until edges are deeply golden brown and caramelized — do not stir during roasting.
  • While cauliflower roasts make the sauce — add green onions, fresh parsley, salt, green chili slices, lemon zest, lemon juice, and extra virgin olive oil to a food processor.
  • Blitz until a thick cohesive textured sauce forms — not completely smooth, some texture is desirable.
  • Taste sauce and adjust seasoning — add more salt, lemon juice, or chili slices to preference.
  • Remove roasted cauliflower from oven and transfer to a large bowl or serving platter.
  • Spoon or pour lemon herb sauce over hot florets and toss gently to coat every piece evenly.
  • Serve immediately while hot.
