Alfredo Sauce

Butter, cream, finely grated Parmigiano-Reggiano, and black pepper become a silky sauce when warmed gently and loosened with hot water.

This standalone Alfredo sauce relies on careful heat and steady whisking rather than a long simmer. Fine cheese and a small amount of hot water help the butter and cream hold a smooth emulsion.

Start with finely grated cheese

Grate the Parmigiano-Reggiano finely so it melts quickly and evenly into the warm cream. Coarse shreds take longer to soften and can leave the sauce uneven before the dairy overheats.

Use low heat throughout

Warm the cream only until it steams, then add cheese in small handfuls while whisking. The mixture should never boil; lift the pan from the burner if bubbles begin to form.

Adjust the texture with hot water

Whisk hot water into the finished sauce a little at a time until it falls fluidly from a spoon. This small addition brings the butter and dairy together in a supple emulsion instead of leaving a heavy, tight coating.

Serve before it tightens

The sauce is at its most fluid while hot and thickens slightly as it rests. A quick whisk before serving restores its sheen, and a little more hot water can loosen it if needed.

Alfredo Sauce

4 servings
16 minutes total

Ingredients

  • •  4 tbsp unsalted butter
  • •  1 cup heavy cream
  • •  1 cup finely grated Parmigiano-Reggiano
  • •  3 tbsp hot water, as needed
  • •  1/4 tsp fine salt
  • •  1/2 tsp freshly ground black pepper

Method

  1. Prepare the ingredients

    Finely grate the Parmigiano-Reggiano and measure the butter, cream, hot water, salt, and black pepper before heating the pan.

    Look for: The cheese is fluffy and fine, with no large shreds that could melt unevenly.

  2. Melt the butter

    Put the butter in a small, heavy-bottomed saucepan and melt it gently, swirling the pan so it melts evenly without browning.

    Look for: The butter is fully liquid and pale, with no browned milk solids.

  3. Warm the cream

    Pour the cream into the melted butter in a slow stream while whisking; keep the pan over low heat until the mixture is steaming, never bubbling.

    Look for: A little steam rises, but the cream stays smooth and shows no simmering bubbles.

  4. Melt in the cheese

    Keep the pan on low and whisk in the grated Parmigiano-Reggiano a small handful at a time, letting each addition melt smooth before adding more; lift the pan off the heat if it starts to bubble.

    Look for: The sauce looks glossy and cohesive, without visible oily patches or grainy clumps.

  5. Loosen and season

    Whisk in one tablespoon of hot water, then add the remaining hot water a teaspoon at a time as needed until the sauce flows from a spoon; season with salt and black pepper.

    Look for: The sauce is fluid and silky while hot, and the pepper is evenly dispersed.

  6. Rest briefly and serve

    Take the pan off the heat and let the sauce stand briefly, then whisk once and serve warm while it still pours easily.

    Look for: The sauce thickens slightly as it rests but remains smooth and spoonable.
