Pasta sauce without heavy cream, and what each way actually costs

Butter, parmesan and starchy pasta water is the creamiest answer, and it is barely lighter than cream. Seven methods, compared on macros per serving.

Common questions

Whole milk thickened with a butter and flour roux is the closest one-for-one replacement, at roughly 75 ml milk with 5 g each of butter and flour per serving. Evaporated milk needs no roux at all and is the lightest of the dairy options. Blended cottage cheese gives the most protein by a wide margin. Full fat coconut milk is the dairy-free choice, and it tastes of coconut, so it suits a tomato or curried sauce rather than a garlic one.

Emulsify rather than substitute. Take the pan off the heat, add cold butter and finely grated parmesan to hot pasta and a few tablespoons of the starchy water it cooked in, then toss hard until the fat and the water bind into a glossy sauce. The starch is what holds it together, which is why pasta water works and tap water does not.

Usually only a little, and sometimes not at all. Our estimate puts 60 ml of heavy cream at about 205 kcal and 22 g of fat per serving, and the butter and parmesan version at about 185 kcal and 17 g of fat. The methods that genuinely cut the numbers are evaporated milk, a milk based bechamel and blended cottage cheese. All macro figures on this page are estimates calculated from typical ingredient values rather than measured.

Yes, but not by pouring it in straight. Milk is about 3% fat against cream at 36%, so it has neither the body to coat pasta nor the fat to protect it from splitting. Thicken it first with a roux, or reduce it with a little starchy pasta water, and keep it below a simmer once the cheese goes in.

No. Double cream is around 48% fat and heavy cream around 36%, so double cream is richer and far more stable in a hot pan. If a recipe written in the United States calls for heavy cream and you have double cream, use about three quarters as much and loosen with pasta water. Going the other way, heavy cream will split where double cream would have held.
