Olive Garden Alfredo Sauce Recipe
Introduction
This Olive Garden-style Alfredo sauce is rich, creamy, and bursting with cheesy flavor. Perfectly paired with fettuccine, it’s a comforting dish that can be made easily at home in about 30 minutes.

Ingredients
- 2 Tbsp butter
- 2 cloves garlic, minced
- 2 Tbsp all-purpose flour
- 2 cups heavy cream
- 1 cup whole milk
- 4 oz grated parmesan cheese
- Salt and pepper to taste
- Fresh parsley, chopped (for garnish)
- Fettuccine pasta (typically 8 oz dry for 4 servings)
Instructions
- Step 1: Melt the butter over medium-high heat in a saucepan. Add the minced garlic and sauté for 1-2 minutes until fragrant, taking care not to burn it.
- Step 2: Whisk in the flour and stir continuously to form a roux. Cook for about one minute to eliminate the raw flour taste.
- Step 3: Gradually whisk in the heavy cream and whole milk. Reduce the heat to low and simmer gently, stirring often until the sauce thickens and bubbles, about 5-7 minutes.
- Step 4: Stir in the grated parmesan cheese and continue cooking on low heat until the cheese has fully melted and the sauce is smooth. Season with salt and pepper to taste.
- Step 5: While the sauce cooks, boil the fettuccine in salted water until al dente, typically 10-12 minutes. Drain well.
- Step 6: Add the drained pasta to the sauce and toss gently to coat the fettuccine evenly.
- Step 7: Garnish with fresh chopped parsley and serve immediately for the best texture and flavor.
Tips & Variations
- For a lighter version, substitute half of the heavy cream with more whole milk or use half-and-half.
- Add cooked chicken, shrimp, or steamed vegetables to turn this into a complete meal.
- Use freshly grated parmesan cheese for best melting and flavor.
- Avoid boiling the sauce; gentle simmer helps prevent curdling and keeps it creamy.
Storage
Store any leftover Alfredo sauce in an airtight container in the refrigerator for up to 3 days. When reheating, warm gently on low heat while stirring to prevent the sauce from separating. It’s best to reheat with a splash of milk to restore creaminess. Leftover pasta with sauce can also be refrigerated and reheated similarly.

Ingredients
Sauce Ingredients
- 2 Tbsp butter
- 2 cloves garlic, minced
- 2 Tbsp all-purpose flour
- 2 cups heavy cream
- 1 cup whole milk
- 4 oz grated Parmesan cheese
- Salt and pepper to taste
Pasta
- 8 oz dry fettuccine pasta (typical quantity for 4 servings)
Garnish
- Fresh parsley, chopped
Instructions
- Prepare the Garlic Butter: Melt 2 tablespoons of butter over medium-high heat in a saucepan. Add the minced garlic and sauté for 1-2 minutes until fragrant, making sure the garlic does not burn to preserve its delicate flavor.
- Make the Roux: Whisk in 2 tablespoons of all-purpose flour into the melted butter and garlic mixture. Stir continuously to form a roux and cook for about one minute to eliminate the raw flour taste while creating a thickening base for the sauce.
- Add Cream and Milk: Gradually whisk in 2 cups of heavy cream and 1 cup of whole milk into the roux. Reduce the heat to low and let the mixture simmer gently, stirring frequently, until the sauce thickens and bubbles, approximately 5-7 minutes.
- Incorporate Parmesan Cheese: Stir in 4 ounces of grated Parmesan cheese. Continue to cook on low heat, stirring until the cheese is fully melted, producing a smooth and creamy sauce. Season with salt and pepper to taste.
- Cook Fettuccine: In a large pot of salted boiling water, cook the fettuccine pasta until al dente, typically 10-12 minutes. Drain well.
- Combine Pasta and Sauce: Add the drained fettuccine directly into the sauce and toss gently but thoroughly to coat all the pasta evenly with the creamy Alfredo sauce.
- Garnish and Serve: Sprinkle freshly chopped parsley over the pasta for a pop of color and fresh herbal note. Serve immediately to enjoy the best texture and flavor.
Notes
