01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper.
02 - In a large bowl, toss the cauliflower florets with 2 tablespoons olive oil and a pinch of salt. Spread evenly on the prepared baking sheet.
03 - Roast the cauliflower for 25–30 minutes, turning once halfway through, until golden and tender.
04 - While the cauliflower roasts, prepare the lemon pepper crunch. In a skillet over medium heat, melt the butter with 1 tablespoon olive oil. Add the breadcrumbs and cook, stirring often, until golden brown and crisp, 3–4 minutes.
05 - Remove the skillet from heat. Stir in the lemon zest, black pepper, sea salt, and chopped parsley.
06 - When the cauliflower is done, transfer to a serving platter. Drizzle with lemon juice, then sprinkle generously with the lemon pepper crunch. Garnish with extra lemon zest and parsley if desired. Serve immediately.
