Olive Garden Alfredo Sauce Recipe
This Olive Garden Alfredo Sauce recipe captures everything that makes the restaurant's version so iconic: a silky, buttery sauce with a deep Parmesan flavor that clings beautifully to every strand of fettuccine. No roux, no flour, just real butter, heavy cream, and freshly grated Parmigiano-Reggiano for a genuinely restaurant-quality sauce in about 20 minutes.
Equipment
- Large pot - for boiling pasta
- Large skillet or sauté pan - 12-inch, preferably stainless steel or enameled
- Box grater or microplane - for grating Parmesan
- Wooden spoon or silicone spatula - for stirring
- Measuring cups and spoons
- Ladle - for reserving pasta water
- Tongs - for tossing pasta in sauce
- Colander - for draining pasta
- Serving bowl - for plating
Ingredients
- 1/2 cup unsalted butter - 113g
- 2 cups heavy whipping cream - 480ml
- 2 cloves garlic - minced
- 2 cups Parmigiano-Reggiano cheese - 180g, freshly grated
- 1/4 teaspoon white pepper - or black pepper
- 1 pinch nutmeg - optional but recommended, freshly grated
- salt - to taste
For Serving
- 1 lb fettuccine pasta - 450g
- fresh parsley - chopped, for garnish
- extra Parmesan cheese - for serving
Instructions
- Bring a large pot of salted water to a rolling boil. Cook fettuccine according to package directions until al dente. Reserve 1 cup of starchy pasta water before draining. Do not rinse the pasta.
- Melt butter in a large skillet over medium-low heat. Add minced garlic and cook for 60-90 seconds, stirring constantly, until fragrant and just barely golden—do not let it brown.
- Pour heavy cream into the skillet and stir to combine. Bring to a gentle simmer over medium heat, then reduce heat slightly and let simmer for 4-5 minutes, stirring frequently, until slightly thickened.
- Reduce heat to low. Add freshly grated Parmigiano-Reggiano a handful at a time, stirring constantly until each addition is fully melted and smooth before adding the next. The sauce should be glossy and coat the back of a spoon.
- Stir in white pepper, a pinch of freshly grated nutmeg, and salt to taste. Adjust seasoning as needed, keeping in mind the Parmesan is already salty.
- Add drained fettuccine directly to the skillet and toss with tongs until every strand is thoroughly coated. If the sauce seems too thick, add a splash of reserved pasta water, 1-2 tablespoons at a time, while tossing.
- Serve immediately in warmed bowls, garnished with extra grated Parmesan and fresh chopped parsley. Alfredo sauce thickens as it cools, so serve right away.
Notes
- Grate your own Parmesan: Pre-shredded cheese contains anti-caking agents that prevent it from melting smoothly, resulting in a grainy sauce. Always grate Parmigiano-Reggiano fresh from a block.
- Keep the heat low for the cheese: Adding Parmesan to cream that is too hot causes the proteins to seize and curdle. Reduce to low heat before adding cheese and stir constantly.
- Don't walk away: This sauce comes together fast and requires your attention. Constant stirring while adding the cheese ensures smooth melting and prevents burning at the bottom of the pan.
- Save the pasta water: The starchy, salted pasta water is liquid gold. A few tablespoons stirred into a thick sauce brings it right back to perfect consistency and helps the sauce cling to the noodles.
- Serve immediately: Alfredo sauce thickens significantly as it cools. Have your pasta, plates, and any protein ready to go before you start the sauce.
- Room temperature cheese: If you have a few extra minutes, take the Parmesan out of the fridge about 20 minutes before you plan to use it for smoother melting.
- Storage: Store leftover sauce or pasta in an airtight container in the refrigerator for up to 3 days. Reheat gently over low heat with a splash of cream or milk to restore consistency.
- Freezing: Cream-based sauces can be frozen for up to 1 month but may separate slightly upon thawing. Thaw overnight in the refrigerator before reheating.
- Variation: For a closer copycat to Olive Garden's recipe, substitute 1/4 cup of the Parmesan with freshly grated Pecorino Romano for a sharper, saltier edge.
- No flour needed: This sauce skips the roux entirely and relies on heavy cream, real butter, and generous Parmesan to build its luxurious body.
