  • Dairy & Liquids
    • 60 ml (1/4 cup) heavy cream

    • 45 g (1/2 cup) grated parmesan cheese, plus more for serving
    • 2 tbsp olive oil

    • 1/4 tsp freshly ground black pepper
    • 1/4 tsp crushed red pepper flakes (optional)
    • 2 tbsp chopped fresh parsley or basil
    • Zest of 1 lemon (optional)

Instructions

1. Preheat oven to 220°C (425°F). Line a baking sheet with parchment paper.
2. Toss cauliflower florets, garlic cloves, and onion with olive oil, salt, and pepper. Spread evenly on the prepared baking sheet.
3. Roast for 25 minutes, flipping halfway, until cauliflower is golden and tender.
4. Meanwhile, cook pasta in a large pot of salted boiling water according to package instructions. Reserve 180 ml (3/4 cup) pasta water, then drain pasta.
5. Transfer roasted cauliflower, garlic, and onion to a blender or food processor. Add heavy cream, milk, parmesan, and half of the reserved pasta water. Blend until completely smooth. Add more pasta water as needed until sauce is creamy and pourable.
6. Return cooked pasta to the pot. Pour the cauliflower sauce over the pasta and toss to coat. Heat gently over low heat for 1–2 minutes, adding extra pasta water for a silkier sauce if desired.
7. Taste and adjust seasoning with salt and pepper. Serve immediately, topped with extra parmesan, chopped herbs, lemon zest, and red pepper flakes if using.

Zusatztipps für die Zubereitung

To ensure the cauliflower roasts evenly and turns golden, spread the vegetables in a single layer and turn them halfway through cooking. Adjust the consistency of the sauce by adding pasta water gradually until it reaches a silky, pourable texture.
