This easy Copycat Olive Garden Alfredo Sauce combines buttery garlic, heavy cream, whole milk, and Parmesan cheese into a silky sauce that’s perfect for fettuccine, chicken Alfredo, shrimp, vegetables, and more.
The secret to a smooth sauce is gently cooking the flour-based roux and adding the dairy gradually, then stirring in the Parmesan over low heat so it melts without becoming grainy.
⏱️ Recipe Information
Prep Time: 5 minutes
Cook Time: 12–15 minutes
Total Time: About 20 minutes
Yield: About 3 cups
Difficulty: Easy
Method: Stovetop
🛒 Ingredients
- 6 tablespoons (85 g) salted butter
- 1 tablespoon minced garlic
- 2 tablespoons (16 g) all-purpose flour
- 1¼ cups (300 ml) heavy whipping cream
- 1½ cups (360 ml) whole milk
- 1 cup (100 g) freshly grated Parmesan cheese
- 1 teaspoon garlic powder
- ½ teaspoon salt
- ¼ teaspoon black pepper, optional
👩🍳 Instructions
1. Melt the Butter
Place a medium saucepan over medium-low heat.
Add the butter and allow it to melt completely.
Avoid letting the butter brown—the goal is a rich, buttery sauce with a clean flavor.
2. Sauté the Garlic
Add the minced garlic.
Cook for approximately 30–60 seconds, stirring constantly, until fragrant.
Don’t let the garlic become dark brown, as it can turn bitter.
3. Make the Roux
Sprinkle the flour over the melted butter and garlic.
Whisk continuously for about 1 minute.
The flour should be fully incorporated and lightly cooked, creating a smooth paste.
4. Add the Cream and Milk
Slowly pour in the heavy cream while whisking constantly.
Once incorporated, gradually add the whole milk.
Continue whisking until the mixture is completely smooth and free of lumps.
5. Season and Simmer
Add the garlic powder, salt, and optional black pepper.
Reduce the heat to low.
Cook gently for approximately 4–6 minutes, stirring frequently, until the sauce begins to thicken.
Do not allow it to boil vigorously. Gentle heat keeps the dairy smooth and prevents scorching.
6. Add the Parmesan
Reduce the heat to very low.
Gradually add the freshly grated Parmesan, a small handful at a time, whisking after each addition until melted and smooth.
Continue until all the Parmesan has been incorporated.
The sauce should be creamy, glossy, and thick enough to coat the back of a spoon.
7. Adjust the Consistency
Remove the saucepan from the heat.
If the sauce is too thick, whisk in 1–2 tablespoons of warm milk at a time until it reaches your desired consistency.
If it’s too thin, return it to very low heat for another minute or two, stirring constantly.
Remember that Alfredo sauce thickens further as it cools.
🍝 How to Make Chicken Alfredo
For a complete restaurant-style meal:
- Cook 12 oz (340 g) fettuccine according to the package directions.
- Reserve about ½ cup pasta water, then drain the pasta.
- Slice 2 boneless, skinless chicken breasts into cutlets or strips.
- Season with salt, pepper, and a little garlic powder.
- Cook the chicken in a lightly oiled skillet until golden and cooked through.
- Toss the hot pasta with the Alfredo sauce.
- Add a splash of reserved pasta water if needed.
- Top with the sliced chicken and extra Parmesan.
Serve immediately while the sauce is silky and creamy.
⭐ Chef’s Tips
Use freshly grated Parmesan: Pre-shredded Parmesan can contain anti-caking agents that prevent it from melting smoothly.
Keep the heat low: High heat can cause the dairy to separate and the Parmesan to become grainy.
Whisk while adding the dairy: Gradually adding the milk and cream prevents lumps from forming.
Don’t boil the sauce: A gentle simmer is all you need.
Add Parmesan off the heat or over very low heat: This helps maintain a smooth, creamy texture.
Serve immediately: Alfredo sauce naturally thickens as it sits.
Reserve pasta water: A splash of starchy pasta water can loosen the sauce while helping it cling beautifully to the noodles.

🧊 Storage
Allow leftover Alfredo sauce to cool slightly before transferring it to an airtight container.
Refrigerate for up to 3–4 days.
🔥 Reheating
Alfredo sauce is best reheated gently.
Place it in a saucepan over low heat and whisk frequently.
Add a splash of milk or heavy cream to restore the creamy consistency.
Avoid boiling.
For microwave reheating, heat in 20–30 second intervals, stirring between each interval.
❄️ Freezing
Freezing is not recommended for the best texture because the dairy-based sauce may separate when thawed.
If you do freeze it, thaw overnight in the refrigerator and reheat very gently while whisking in a little milk or cream.
