Homemade Alfredo Sauce with Heavy Whipping Cream is a quick-prep, rich, creamy sauce with a weeknight-friendly cooking method that turns a handful of ingredients into a smooth, restaurant-style sauce. Butter, fresh garlic, heavy whipping cream, and Parmesan melt together over gentle heat to create an easy Alfredo sauce recipe that coats pasta perfectly.
Melt the butter in a medium saucepan over medium-low heat. Add the garlic and cook for 20 to 30 seconds, stirring constantly, until fragrant.
Pour in the heavy cream and stir to combine. Bring to a very gentle simmer and cook for 2 to 3 minutes until slightly warmed and lightly thickened. Do not boil.
Reduce the heat to low. Add the freshly grated Parmigiano Reggiano gradually, whisking between additions until melted and smooth. Stir in the white pepper, salt, and nutmeg if using.
Remove the saucepan from heat and let the sauce rest for 1 minute.
Toss immediately with hot cooked pasta or spoon over chicken, shrimp, vegetables, or baked dishes. The sauce will continue to thicken slightly as it sits.

Notes
Cooking NotesKeep the cream below a boil and add the cheese gradually for the smoothest finish. Letting the sauce rest briefly before serving gives it time to thicken naturally.Tips for Best Results
Keep the heat low once the cream is added.
Add Parmesan gradually for a glossy texture.
Warm leftovers gently instead of using high heat.
Let the finished sauce sit for one minute before serving.
How to Know It’s ReadyThe finished Alfredo should look smooth, glossy, and thick enough to lightly coat the back of a spoon. When tossed with hot pasta, the sauce should cling instead of pooling at the bottom.
