Roasted Rainbow Cauliflower with Parmesan & Lemon
At the farmers market, I love picking up colorful cauliflower-purple, orange, green Romanesco, and white. Each color isn’t just pretty-it brings different antioxidants and plant compounds that support immunity and cellular health. Roasting brings out the natural sweetness, and a sprinkle of Parmesan adds that savory, nutty finish (and a dose of vitamin K2).
- 1 head rainbow cauliflower (mix of purple, orange, green, or white-whatever you find)
- 2 tbsp olive oil extra virgin
- 1 pinch sea salt & black pepper
- 1/2 cup freshly grated Parmesan (or try Gouda, Jarlsberg, or Emmenthal for extra vitamin K2 benefits)
- 1/2 tsp lemon zest grated
- 1 pinch chili flakes or fresh parsley for garnish (optional)
Preheat the oven to 400°F (200°C). Line a baking sheet with parchment.
Prep the cauliflower: Cut into florets. Toss with olive oil, salt, and pepper.
Roast for 20–25 minutes, tossing once, until the edges are golden and caramelized.
Remove from the oven and immediately sprinkle with Parmesan and lemon zest. Garnish with chili flakes or parsley if you like.
Optional Add‑Ons & Swaps
- Add a sprinkle of turmeric to the olive oil for an extra anti-inflammatory boost.
- Swap Parmesan for aged Gouda or Jarlsberg, which have vitamin K2 linked to reduced lung and prostate cancer risk.
Squeeze a little lemon juice over just before serving for brightness.
Why It’s Healing
- Purple cauliflower contains anthocyanins (the same antioxidants in berries) that reduce oxidative stress.
- Orange cauliflower is rich in beta-carotene, a precursor to vitamin A that supports immune and skin health.
- Green Romanesco has chlorophyll and lutein for anti-inflammatory, eye, and cellular benefits.
- Classic white cauliflower is packed with sulforaphane, a natural compound that supports detoxification and kills cancer cells in lab studies.
- Parmesan and other hard cheeses provide vitamin K2, linked to reduced risk of lung and prostate cancer.
- Olive oil adds healthy fats that help absorb fat-soluble antioxidants.
- Lemon zest brings vitamin C and flavonoids that help protect cells.
Tip: Buying cauliflower in different colors isn’t just for looks, each hue reflects unique phytonutrients. Mixing them helps you “eat the rainbow” for a broader spectrum of protection.
