Here’s What You’ll Need
- Purple Cauliflower: This vibrant vegetable is the star of the show, bringing a stunning purple hue and a mild, slightly nutty flavor to the dish. Its rich color is due to the presence of anthocyanins, which are antioxidants known for their health benefits. Learn more about purple cauliflower and where to buy it here!
- Olive Oil: The olive oil serves as the perfect roasting agent, helping to caramelize the cauliflower while infusing it with a little flavor. Look for high-quality extra-virgin olive oil for the best results.
- Salt and Pepper: These essential seasonings enhance the natural flavors of the cauliflower and balance out the richness of the Parmesan cheese.
- Freshly Grated Parmesan Cheese: The parmesan cheese adds a nutty and savory note, creating a delightful contrast to the sweetness of the roasted cauliflower. Be sure to use freshly grated Parmesan for the best texture and flavor (pre-grated parmesan has anti-caking starch mixed in, which adds a flavor you don’t want).
Does It Need To Be Purple?
When selecting purple cauliflower, choose heads with firm and compact florets, and avoid any that have signs of wilting or discoloration. If you can’t find purple cauliflower, you can still make this recipe using regular white cauliflower.
How to Roast Purple Cauliflower
Step 1: Prep
Preheat oven to 425°F (218°C). Cut cauliflower into either 1-inch slabs or bite-sized florets (or both). I like to cut larger “steaks” to showcase that gorgeous color!
Step 2: Cook
Place the cauliflower pieces on a parchment-lined baking sheet, which helps prevent sticking and makes cleanup a breeze. Drizzle the olive oil over the cauliflower, then sprinkle with the salt and pepper. Use your hands or a spoon to toss the cauliflower around gently, ensuring that every piece is evenly coated with the oil and seasonings. Roast the cauliflower just until it begins to brown. You’ll know it’s ready when the edges are just starting to turn golden brown, and the cauliflower is tender but still has a slight bite.
Step 3: Cheese
It’s time to add the cheesy finishing touch to your roasted cauliflower. Take the baking sheet out of the oven and evenly sprinkle the freshly grated Parmesan cheese over the cauliflower. Return the baking sheet to the oven and let it cook for a few more minutes until the cheese becomes slightly browned and crispy.
