A restaurant-quality, creamy Alfredo sauce inspired by Olive Garden—rich, silky, and garlicky, made from scratch in just six easy steps.

  • Total Time: 20 minutes
  • Yield: 6 servings

Ingredients

1 lb (16 oz) fettuccine pasta

1/2 cup (1 stick) salted butter

2 cloves garlic, minced

1/2 tsp garlic powder

1/2 tsp salt (or to taste)

2 tbsp all-purpose flour

1 1/4 cups heavy whipping cream

1 1/2 cups whole milk

1 1/2 cups freshly grated Parmesan cheese

2 tbsp fresh parsley, chopped (for garnish)

Instructions

  1. Cook fettuccine according to package directions, drain, and set aside.
  2. In a large skillet over medium heat, melt butter. Add minced garlic, garlic powder, and salt; whisk to combine.
  3. Sprinkle flour over the mixture and whisk again. Slowly add heavy cream and whole milk while whisking continuously. Bring to a boil, then reduce heat to low and simmer for 2–3 minutes.
  4. Gradually whisk in Parmesan cheese until the sauce is smooth and creamy.
  5. Add cooked fettuccine to the sauce and toss with tongs until well coated.
  6. Garnish with fresh parsley and serve immediately.

Notes

  • Substitute linguine, pappardelle, tagliatelle, bucatini, penne, rigatoni, or cavatappi for variety.
  • For extra protein, add grilled chicken, sautéed shrimp, or flaked salmon.
  • Incorporate vegetables like steamed broccoli, sautéed mushrooms, roasted peppers, or asparagus for extra flavor and color.
  • Refrigerate leftovers in an airtight container for 3–4 days or freeze for up to 2 months (texture may change).
  • Reheat gently over low heat, loosening with milk, cream, chicken broth, or pasta water if necessary.
