This easy homemade Alfredo sauce from scratch is rich, creamy, and better than store-bought. Made with simple ingredients like butter, heavy cream, and freshly grated Parmesan cheese, this creamy Alfredo sauce recipe comes together in just minutes and is perfect for pasta, chicken, or dipping garlic bread.
½ cup unsalted butter
2 cups heavy cream
3 cloves garlic, minced
1 ½ cups freshly grated Parmesan cheese
½ teaspoon salt (or to taste)
¼ teaspoon black pepper
Optional: ½ teaspoon Italian seasoning or pinch of nutmeg
In a large skillet over medium heat, melt the butter until fully melted but not browned.
Add the minced garlic and sauté for 30–60 seconds until fragrant.
Slowly pour in the heavy cream and stir continuously. Bring to a gentle simmer, but do not boil.
Reduce heat to low and gradually whisk in the freshly grated Parmesan cheese. Stir until the cheese melts and the sauce becomes smooth and creamy.
Let the Alfredo sauce simmer for 3–5 minutes, stirring often, until thickened to your desired consistency.
Season with salt and black pepper to taste.
Serve immediately over fettuccine, chicken, shrimp, or vegetables.
Use freshly grated Parmesan for the smoothest, creamiest Alfredo sauce.
Do not let the sauce boil, or it may separate.
If the sauce is too thick, add a splash of reserved pasta water or extra cream.
Alfredo sauce thickens as it cools.
