Prep: Preheat the oven to 425°F and line a baking sheet with parchment paper for easy cleanup. Wash and trim the cauliflower, and cut into medium-sized florets.
Combine: Place the cauliflower florets in a large mixing bowl, drizzle the oil and butter over them, and sprinkle everything with garlic powder, salt and pepper. Mix well to combine and pour out onto the prepared baking sheet.
Roast: Place the baking sheet in the oven for 20-25 minutes or until golden brown, turning the florets once halfway through.
Enjoy: Top with extra salt and pepper to taste, and garnish with freshly chopped parsley if desired. Serve immediately, and enjoy!
Notes
Storage: Oven roasted cauliflower will stay fresh in an airtight container in the fridge for up to 4 days, or in the freezer for up to 2 months.
