Make the classic Olive Garden Alfredo Sauce at home in just 20 minutes. This creamy, cheesy sauce pairs perfectly with fettuccine for a comforting Italian main course that the whole family will love.

  • Total Time: 20 minutes
  • Yield: 6 servings

Ingredients

Sauce Ingredients

  • 6 Tablespoons salted butter, high quality
  • 1 Tablespoon garlic, minced
  • 2 Tablespoons all-purpose flour
  • 1 ½ cups heavy cream
  • 1 ½ cups whole milk (1% or 2% can be used if needed)
  • ½ cup Parmesan cheese, grated and at room temperature
  • ½ cup Romano cheese, grated and at room temperature
  • Salt and black pepper to taste

Pasta

  • 1 lb. Fettuccine

Garnish

  • Parsley, to garnish

Instructions

  1. Boil the pasta: Boil the fettuccine according to the package instructions. Start this as you begin preparing the sauce so both finish around the same time.
  2. Melt butter and cook garlic: In a large saucepan over medium heat, melt the salted butter. Add the minced garlic and cook for about one minute until fragrant but not browned.
  3. Add flour: Whisk in the all-purpose flour and cook for one minute, stirring continuously to form a roux and remove the raw flour taste.
  4. Add cream and milk: Slowly add the heavy cream in splashes while stirring constantly, followed by the milk in the same manner. This helps prevent lumps and ensures a smooth sauce.
  5. Simmer and thicken: Bring the mixture to a gentle bubble, then reduce heat to low and let it simmer. The sauce will thicken as it simmers.
  6. Incorporate cheeses: Reduce heat to the lowest setting and slowly stir in the grated Parmesan and Romano cheeses until melted and smooth. Season with salt and black pepper to taste.
  7. Drain pasta and mix: Drain the cooked fettuccine and add it directly to the sauce, stirring until the pasta is well coated and the sauce thickens further by absorption.
  8. Garnish and serve: Garnish with chopped parsley and serve immediately for best flavor and texture.

Notes

  • The sauce continues to thicken after standing and when combined with pasta, so avoid adding extra cheese just to thicken it initially.
  • For a saucier pasta, reduce pasta to 3/4 lb.
  • When reheating, Alfredo sauce can thicken too much; gently reheat on stove or microwave and add a splash of milk or chicken broth if needed.
  • The best reheating method is a double boiler to restore the sauce’s original silky texture.
  • Frozen Alfredo sauce should be thawed overnight in the refrigerator before reheating.
  • Serve alongside an Olive Garden Salad for a classic meal pairing.
