Easy Creamy Cauliflower Alfredo

Featured in: Family Table Cooking

This velvety pasta dish transforms cauliflower into an incredibly smooth sauce that rivals traditional Alfredo. The florets simmer with garlic and onion until tender, then blend with butter, Parmesan, and milk into a luxurious cream coating for fettuccine or linguine.

What makes this version special is how the cauliflower naturally thickens the sauce while keeping it light—just 350 calories per serving. The nutmeg adds subtle warmth, while the Parmesan brings that classic Italian depth. Reserve pasta water to adjust consistency perfectly.

Ready in under an hour, this works for weeknight dinners yet feels elegant enough for guests. The sauce stays creamy when reheated, making it excellent for meal prep too.

  • Vegetables: 1 medium head cauliflower, cut into florets (about 700 g); 3 cloves garlic, peeled; 1 small yellow onion, chopped
  • Dairy & Alternatives: 2 tablespoons unsalted butter; 1/3 cup grated Parmesan cheese (plus extra for serving); 1/2 cup milk (dairy or unsweetened plant-based)
  • Pasta: 350 g fettuccine or linguine
  • Seasonings: 1 teaspoon salt, plus more to taste; 1/2 teaspoon freshly ground black pepper; pinch of ground nutmeg (optional)
  • Garnishes: Fresh parsley, chopped (optional); extra Parmesan (optional)

Instructions

1. Boil the Vegetables
Bring a large pot of salted water to a boil. Add cauliflower florets, garlic, and chopped onion. Cook for 8–10 minutes until cauliflower is very tender.
2. Blend the Sauce
Using a slotted spoon, transfer the cooked vegetables to a blender. Add butter, Parmesan cheese, milk, salt, pepper, and nutmeg (if using). Blend until completely smooth and creamy. Add a splash of cooking water if needed to reach desired consistency.
3. Prepare the Pasta
In the same pot, cook pasta according to package instructions until al dente. Reserve 1 cup of pasta water, then drain.
4. Combine and Toss
Return drained pasta to the pot. Pour over the cauliflower Alfredo sauce and toss well to coat, adding reserved pasta water as needed for extra creaminess. Taste and adjust seasoning.

Zusatztipps für die Zubereitung

To ensure the most velvety texture, make sure the cauliflower is soft enough to be easily pierced with a fork before blending. A high-powered blender will yield the smoothest results, but a standard food processor can also work if you blend it for a few extra minutes.

Varianten und Anpassungen

For a vegan version, simply swap the dairy for plant-based milk, vegan butter, and nutritional yeast instead of Parmesan. This dish also pairs beautifully with sautéed mushrooms or steamed broccoli if you want to add more texture and greens.

Serviervorschläge

Serve the pasta hot, garnished with a generous handful of fresh chopped parsley and extra grated Parmesan. A crack of freshly ground black pepper on top adds a nice bite that complements the sweetness of the cauliflower.

Recipe Questions

Does cauliflower Alfredo taste like traditional Alfredo sauce?

Yes! The cauliflower creates a remarkably similar creamy texture, while Parmesan and butter provide that familiar rich Alfredo flavor most people love.

Can I make this cauliflower Alfredo vegan?

Absolutely. Substitute plant-based milk, vegan butter, and nutritional yeast or vegan Parmesan for the dairy components. The sauce remains equally smooth and satisfying.

What pasta shapes work best with this sauce?

Fettuccine, linguine, or tagliatelle are ideal because their wide surface area holds the creamy sauce beautifully. Penne or rigatoni also work if you prefer shorter pasta.

How long does this keep in the refrigerator?

Store in an airtight container for up to 4 days. The sauce may thicken when cold—simply thin with a splash of water or milk when reheating on the stove.

Can I freeze the cauliflower Alfredo sauce?

Yes, freeze the sauce separately for up to 3 months. Thaw overnight in the refrigerator, then reheat gently. Fresh-cooked pasta works best rather than freezing combined leftovers.

Why add nutmeg to Alfredo sauce?

A pinch of nutmeg enhances the creaminess and adds subtle warmth that complements the cauliflower's mild flavor. It's a classic Italian technique for white sauces.
