🥕Ingredients
Tap to check off as you go
- 12 ounces fettuccine pasta
- 3 tablespoons unsalted butter
- 3 cloves garlic, minced
- 1 cup heavy cream
- 1 cup freshly grated Parmesan cheese
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 2 tablespoons fresh parsley, chopped (optional)
📋Instructions
- 1
Bring a large pot of salted water to a boil. Cook fettuccine according to package directions until al dente. Reserve 1/2 cup pasta water before draining.
- 2
While pasta cooks, melt butter in a large skillet over medium heat. Add minced garlic and sauté for 1 minute until fragrant.
- 3
Pour in heavy cream, stirring constantly. Bring to a gentle simmer, then reduce heat to low.
- 4
Gradually whisk in Parmesan cheese until melted and smooth. Season with salt and pepper.
- 5
Drain the pasta and add it directly to the skillet with the sauce. Toss to coat, adding a splash of reserved pasta water if the sauce is too thick.
- 6
Serve immediately, garnished with fresh parsley and extra Parmesan.
💡 Pro Tips
- •Use freshly grated Parmesan — pre-shredded won't melt as smoothly.
- •Reserve pasta water before draining; its starch helps thicken the sauce.
- •Don't let the sauce boil after adding cheese, or it may become grainy.

Pro Cooking Tip
For the silkiest sauce, always use freshly grated Parmesan from a block. Pre-grated cheese often contains anti-caking agents that prevent smooth melting.
Serving Suggestions
This fettuccine alfredo is delicious on its own, but you can easily turn it into a heartier meal. Serve it alongside a crisp green salad with lemon vinaigrette, or add grilled chicken, shrimp, or steamed broccoli for extra protein and veggies. A glass of Sauvignon Blanc or Pinot Grigio pairs beautifully with the creamy sauce.
