The Homemade Alfredo Sauce You'd Never Guess Takes Only 15 Minutes
This homemade alfredo sauce comes together in 15 minutes with just 6 pantry staples. It's silky, restaurant-smooth, and the one pasta recipe my kids beg for on busy school nights. Keep the heat low, grate fresh parmesan, and save a little pasta water for a glossy finish every time.
Equipment
- Large Pot
- Large skillet or saucepan (10 to 12 inches)
- Whisk
- Fine grater (microplane or box grater)
- Measuring cups
Ingredients
For the Sauce
- 1/2 cup unsalted butter (1 stick)
- 1 cup heavy cream
- 1 cup freshly grated Parmesan cheese (about 4 ounces)
- 2 cloves garlic, minced (or 1/2 teaspoon garlic powder)
- 1/4 teaspoon salt, plus more to taste
- Freshly cracked black pepper, to taste
- 1 pinch ground nutmeg (optional)
For Serving
- 12 ounces fettuccine
- 1/2 cup reserved pasta water
Instructions
- Bring a large pot of generously salted water to a rolling boil and cook the fettuccine according to package directions. Before draining, reserve about 1 cup of pasta water.
- In a large skillet or saucepan over medium-low heat, melt the butter until foamy. Do not let it brown.
- Add the minced garlic and cook for 30 to 60 seconds, just until fragrant. If the garlic starts to brown, pull the pan off the heat.
- Slowly pour in the heavy cream while whisking. Turn the heat up to medium and bring to a gentle simmer — small bubbles around the edges, not a rolling boil.
- Reduce the heat to low. Add the grated parmesan in three or four small handfuls, whisking constantly until each handful melts completely before adding the next.
- Stir in salt, cracked black pepper, and the pinch of nutmeg if using. Cook on low for 2 to 3 minutes, stirring occasionally, until the sauce coats the back of a spoon.
- Add the hot drained fettuccine to the sauce and toss to coat. Add reserved pasta water 1 to 2 tablespoons at a time until the sauce turns glossy and clings to every strand.
- Serve immediately topped with extra parmesan and cracked black pepper.
Notes
Make ahead: Grate the parmesan, mince the garlic, and measure the cream the night before to cut weeknight prep. Cook the sauce fresh for the best texture.
Storage: Leftover alfredo keeps in an airtight container in the fridge for up to 3 days. Reheat low and slow on the stovetop with a splash of milk or pasta water, whisking until smooth. Freezing is not recommended because cream sauces turn grainy.
