If you’ve ever wanted to create restaurant-quality Alfredo at home, this is the recipe you’ll keep forever.
The History Behind Alfredo Sauce
Traditional Italian Alfredo isn’t what Americans know today. In Rome, Alfredo is simply:
- butter
- parmesan
- pasta water
- fettuccine
Americans added the cream, making it richer and smoother. The result is a velvety sauce that coats pasta beautifully and has become a comfort-food classic in home kitchens and restaurants.
Our recipe uses the American-style technique but keeps the ingredients simple so the flavor shines through.

Ingredients Breakdown
Butter
Creates the foundation of richness and helps melt the parmesan smoothly.
Garlic
Just enough to add aroma without overpowering the sauce.
Heavy Cream
The base that creates an ultra-silky texture.
Parmesan Cheese
The star ingredient. Freshly grated is essential — pre-grated has anti-caking agents and won’t melt smoothly.
Salt & Pepper
Enhances and sharpens flavor.
Nutmeg (optional)
A tiny pinch elevates the creaminess without tasting like nutmeg.

- 4 tbsp unsalted butter
- 3 cloves garlic, minced
- 1½ cups heavy cream
- 1½ cups freshly grated parmesan cheese
