Introduction
Heavy cream, butter, and grated Parmesan cook into a dense, glossy sauce, with a pinch of fresh-ground nutmeg keeping it from tasting flat. The pasta finishes in the pan for 1–2 minutes, so you get a sauce that clings well and a dinner that fits easily into a weeknight.
Recipe Details
- Prep Time: 5 minutes
- Cook Time: 15 minutes
- Total Time: 20 minutes
- Servings: 4
Ingredients
- 1¾ cups (400 ml) heavy cream
- 6 tbsp unsalted butter
- 8.5 ounces (240 g) grated Parmesan cheese or asiago cheese
- 1 tsp salt
- Fresh-ground black pepper
- 1 pinch of fresh-ground nutmeg
Instructions
- Combine 1¼ cups (300 ml) cream and the butter in a saucepan large enough to accommodate the sauce and later the pound of pasta.
- Heat over a low flame, stirring frequently, until the butter is melted and the cream comes to a bare simmer.
- Remove the pan from the heat once the butter is evenly incorporated into the cream.
- Cook the pasta, draining it a little before it reaches the al dente stage. The pasta should be slightly undercooked before being added to the sauce because it will continue to cook while the sauce is being finished.
- Drain the pasta.
- Add the drained pasta, ½ cup (100 ml) of cream, the cheese, the salt, the nutmeg, and several grinds of the pepper mill to the pan
- Heat the pasta and sauce over a low flame, tossing continuously, until the cheese melts into the sauce and the sauce thickens slightly, about 1-2 minutes. You can add chopped parsley as a garnish mixed into the sauce.
Variations
- Use asiago cheese instead of Parmesan for a sharper, saltier sauce with a slightly more pronounced tang.
- Add the chopped parsley garnish mentioned in the final step to cut the richness and give the finished pasta a fresher edge.
- Change the pasta shape: fettuccine gives you long strands fully coated in sauce, while rigatoni or penne hold the sauce inside the tubes.
- Add cooked peas or sautéed mushrooms when you toss the pasta with the sauce if you want more texture and a fuller one-bowl meal.
Tips for Success
- Keep the heat low when melting the butter into the cream; a hard boil can make the sauce look greasy instead of smooth.
- Drain the pasta a little before al dente, as directed, so it finishes in the sauce without turning soft.
- Have the cheese measured and ready before the pasta is drained, because the final sauce comes together in about 1–2 minutes.
- Toss continuously in the last step so the cheese melts evenly into the cream instead of clumping.
- Use a light hand with the nutmeg; it should round out the sauce, not dominate it.
Storage and Reheating
Store leftovers in an airtight container in the fridge for up to 3 days. Freezing is not recommended, since the cream-and-cheese sauce can separate and turn grainy when thawed.
Reheat on the stovetop over low heat with a small splash of cream, milk, or water to loosen the sauce, stirring until smooth. You can also microwave it in short bursts at 50% power, stirring between each burst so the cheese does not tighten.
FAQ
Can you use pre-grated Parmesan?
You can, but finely grated Parmesan from a block melts more smoothly. Pre-grated cheese often contains anti-caking agents that can make the sauce a little grainier.
Why do you undercook the pasta before adding it to the sauce?
The pasta keeps cooking in the cream and cheese during the final toss. Starting with slightly undercooked pasta keeps the final texture from going past al dente.
Can you substitute asiago for Parmesan?
Yes. Asiago gives you a sharper, saltier flavor, so taste before adding the full teaspoon of salt.
Why did the sauce turn oily or clumpy?
The heat was likely too high, or the cheese did not melt in gradually while you tossed the pasta. Keep the flame low and keep the pasta moving until the sauce looks smooth and lightly thickened.
