Overview

Classic Fettuccine Alfredo is a beloved, simple pasta dish of silky sauce made from butter, cream, and Parmesan. This version is tuned for home cooks who want a reliably rich, smooth sauce without fuss — perfect for a weeknight dinner. Freshly grated Parmesan and starchy pasta water are the keys.

Yield & Time

• Serves: 2–3
• Active time: 15 minutes
• Total time: 20–25 minutes

Ingredients

• 8 oz (225 g) fettuccine or other long pasta
• 3 tablespoons unsalted butter
• 1 cup (240 ml) heavy cream
• 1 cup (100 g) freshly grated Parmesan cheese, plus extra for serving
• 1 small garlic clove, finely minced (optional)
• Salt and freshly ground black pepper, to taste
• 1–2 tablespoons reserved pasta cooking water (more as needed)
• 1 tablespoon chopped fresh parsley or chives, for garnish (optional)

Equipment

• Large pot for boiling pasta
• Large sauté pan or shallow skillet (wide enough to toss pasta)
• Tongs or pasta fork
• Cheese grater
• Measuring cups and spoons

Before You Start

• Bring a large pot of salted water to a boil while you prep the sauce. Use about 1 tablespoon of salt per 4–6 quarts of water — the pasta should taste pleasantly seasoned.
• Grate the Parmesan fresh; pre-shredded cheese contains anti-caking agents that prevent a smooth melt.

Instructions

1. Cook the pasta

1. Add the fettuccine to the boiling water and cook until al dente, usually 1–2 minutes less than the package suggests (about 9–11 minutes depending on brand).
2. Before draining, reserve 1 cup (240 ml) of the pasta cooking water. Drain the pasta, shaking off excess water.

2. Make the sauce

1. While the pasta cooks, heat a large sauté pan over medium-low heat. Add the butter and let it melt gently. If using garlic, add it now and cook 20–30 seconds until fragrant — do not brown.
2. Pour the heavy cream into the pan and warm until small bubbles form around the edges, about 1–2 minutes. Keep the heat low so the cream does not boil vigorously.

3. Emulsify pasta and cheese

1. Add the drained pasta to the pan with the cream and butter. Toss to combine.
2. Remove the pan from the heat. Add the grated Parmesan in small handfuls, tossing or stirring constantly until the cheese melts into a smooth sauce. If the sauce seems too thick or clings without coating the noodles, add 1–2 tablespoons of reserved pasta water at a time until you reach a glossy, silky consistency. You may need up to 1/4 cup (60 ml) depending on the pasta and cheese.
3. Season with salt and plenty of freshly ground black pepper. Taste and adjust.

4. Finish and serve

1. Transfer the pasta to warmed plates or bowls. Sprinkle with additional Parmesan and chopped parsley or chives if using. Serve immediately while the sauce is warm and creamy.

Tips for Success

• Use the right cheese: Parmigiano-Reggiano or a good-quality Parmesan works best. Avoid pre-grated blends for texture and flavor.
• Low heat when adding cheese: Remove the pan from direct heat before adding the cheese to prevent grainy, separated sauce. The residual heat melts the cheese gently.
• Pasta water is magic: The starch in the reserved water helps emulsify the sauce, making it glossy and cling to the noodles. Add a splash at a time.
• Don’t overcook the pasta: Slightly undercooked (al dente) pasta finishes cooking in the sauce and keeps good texture.

Easy Variations

• Chicken Alfredo: Slice a cooked chicken breast and toss on top, or pan-sear seasoned chicken strips and combine with the pasta.
• Shrimp Alfredo: Sear shrimp in butter and garlic, then mix into the finished pasta.
• Lemon & Herb: Stir in 1 teaspoon of lemon zest and a handful of chopped parsley for brightness.
• Veggie Twist: Fold in blanched peas, sautéed mushrooms, or roasted broccoli for color and texture.

Make-Ahead, Storage & Reheating

• Refrigerate leftovers in an airtight container for up to 3 days. The sauce may thicken as it cools.
• To reheat, warm gently on the stovetop over low heat with a splash of cream, milk, or reserved pasta water to restore a silky texture. Heat just until warmed through — do not boil.
