Good cheese, good vegetables, good pasta. What more could you need? These quick creamy noodles rely on one thing: a stellar homemade Alfredo sauce. Butter, cream and cheese get you there, anchored by the musky aroma of nutmeg. Adding cauliflower to the boiling pasta in the last few minutes of cooking results in a lighter, glossier final sauce. Serve with an arugula salad, dressed simply with lemon juice, salt, pepper, crushed red pepper, extra-virgin olive oil and more grated cheese.

Preparation

  1. Step 1

    Bring a large pot of salted water to a boil. Cook the pasta according to package instructions. In the last 3 minutes of cooking, add the cauliflower. Reserve 1 cup of the pasta cooking water. Drain the pasta and vegetables and return to the pot.

  2. Step 2

    Meanwhile, in a small saucepan over medium, melt 1 tablespoon of butter. Add the shallot and cook, stirring frequently, until softened, about 2 minutes. Add the cream, reduce the heat to low, then cook without boiling, stirring occasionally, until warmed through and slightly thickened, about 2 minutes.

  3. Step 3

    Stir in the Parmigiano-Reggiano and 1 tablespoon of butter. Taste and season with salt, pepper, nutmeg and more Parmigiano, as needed.

  4. Step 4

    Scrape the sauce into the pot with the cooked pasta and cauliflower, splashing in some of the reserved pasta water as needed to thin out the sauce. Add the remaining 1 tablespoon of butter. Over medium heat, toss until the sauce thickens slightly and clings to the pasta. Taste the pasta once more and season with salt, if it needs it.

  5. Step 5

    Serve immediately with a generous sprinkling of chives. Optionally, you can also enjoy this creamy pasta with dollops of cool ricotta, a squeeze of fresh lemon or a handful of arugula on top.

Drain pasta and cauliflower (and 1/2 cup peas) and leave in strainer. USING THE SAME POT, make cream sauce, dump pasta and veg into sauce and proceed, knowing you have only 1 pot to wash at the end. Lemon zest is a must-have.

Do yourself a favor and just toss the cauliflower with oil, a garlic herb rub or paprika or something, and throw it in the oven at the beginning. Just needs to be there at 425 for like 20 minutes. It’s so much better than boiled cauliflower..

@Chuck Well, sure, but that would be an entirely different recipe. Boiled cauliflower works well with this creamy pasta recipe.

Buckle up, pitchfork-wielding mob - I made a mockery of this recipe in the name of macros and I’d do it again. Subbed Brami pasta for regular, evaporated milk for heavy cream, skipped the last tbsp of butter, and added 1/2 lb ground turkey cooked with garlic and red pepper. Parm instead of pecorino because it was in the fridge. Kept all instructions and ratios the same (using the one-pot notes from others) and it was delicious. I’ll make sure I have arugula next time - because there will be a next time.

Instead of adding the butter while cooking, I made brown butter and just added it before serving- was amazing.

Rather bland. Needs a more robust alfredo sauce. I included chopped walnuts at the end. My usual alfredo proportions: 6 tablespoons unsalted butter 1 shallot, minced 1 cup heavy cream 1 cup finely grated ParmigianoReggiano 1/2 teaspoon salt 1/4 teaspoon freshly ground black pepper
