This creamy Alfredo sauce combines butter, garlic, heavy cream, milk, and freshly grated Parmesan cheese for a rich and smooth texture. Perfect for fettuccine, pasta dishes, or as a versatile sauce for vegetables and chicken, this homemade Alfredo sauce is easy to prepare with simple ingredients.

Ingredients
- 1 tablespoon butter
- 4 cloves garlic, pressed or finely minced
- 1 tablespoon all-purpose flour
- 1 cup heavy cream
- 1 cup milk (2% recommended)
- 1 cup (about 1 ½ ounces) freshly grated Parmesan cheese
- ½ teaspoon fine sea salt
- Pinch of white pepper
- Pinch of ground nutmeg (optional)
Instructions
- Sauté the Garlic: In a large saucepan or sauté pan, melt the butter over medium-high heat. Add the minced garlic and cook, stirring frequently, for about 1 minute until fragrant.
- Add Flour: Stir in the flour and continue to sauté for another minute, stirring constantly to form a smooth roux.
- Combine Milk and Cream: Gradually whisk in the heavy cream and milk until fully combined and smooth.

- Add Cheese and Season: Stir in the freshly grated Parmesan cheese, salt, white pepper, and nutmeg (if using). Whisk until the cheese melts completely and the sauce is smooth and creamy.
