Instructions

Roast the cauliflower

Preheat oven to 425°F (220°C). Toss cauliflower with olive oil, smoked paprika, salt, and pepper. Spread on a baking sheet and roast 20‑25 minutes, turning halfway, until golden and tender.

Pro Tip: High heat caramelizes the edges, creating natural sweetness for the sauce.

Cook the pasta

While cauliflower roasts, bring a large pot of salted water to boil. Add linguine and cook 8‑10 minutes until al dente. Reserve ½ cup pasta water, then drain.

Pro Tip: The reserved water helps thin the sauce without losing flavor.

Blend the cauliflower sauce

Transfer roasted cauliflower to a high‑speed blender. Add milk, cream cheese, half the Parmesan, and a pinch of salt. Blend until completely smooth, about 30 seconds. Adjust seasoning.

Pro Tip: If the sauce is too thick, incorporate a splash of the reserved pasta water.

Combine pasta and sauce

Return the drained linguine to the pot over low heat. Pour the cauliflower sauce over the pasta, tossing to coat evenly. Add remaining Parmesan and a drizzle of olive oil; stir until glossy.

Pro Tip: Heat gently; high heat can cause the sauce to separate.

Finish and serve

Plate the pasta, sprinkle with fresh parsley, extra Parmesan, and a grind of black pepper. Serve immediately while the sauce is warm and velvety.

Pro Tip: A squeeze of lemon juice brightens the final dish.

Expert Tips

Tip #1: Roast longer for deeper flavor

If you prefer a richer, caramelized sauce, extend roasting by 5‑7 minutes. The extra browning adds a subtle nutty note that elevates the whole dish.

Tip #2: Use an immersion blender for speed

If you lack a countertop blender, an immersion blender works directly in the pot. Blend until silky, adding liquid gradually to control consistency.

Tip #3: Add a pinch of nutmeg

A tiny dash of freshly grated nutmeg deepens the creaminess without overpowering the cauliflower’s natural sweetness.

Frequently Asked Questions

Yes. Thaw completely, pat dry, and follow the same roasting steps. Frozen florets may release more moisture, so extend roasting by a few minutes to achieve caramelization.

Keep the sauce on low heat and add liquid (pasta water or milk) gradually. Stir constantly; avoid boiling, which can cause the dairy proteins to split.

Long, flat shapes like linguine or fettuccine cling to the creamy sauce, but any sturdy pasta (penne, rigatoni) will hold the cauliflower coating nicely.
