This homemade Fettuccine Alfredo delivers rich, velvety cream sauce made from scratch with garlic, Parmesan, and a touch of nutmeg. Add pan-seared chicken breast for a satisfying protein boost, or keep it meatless for a classic version. Either way, this dish is comfort food perfection.

Ingredients

For the Pan-Seared Chicken (Optional)

2 boneless, skinless chicken breasts
Fine sea salt and freshly ground black pepper
1 tablespoon olive oil

For the Fettuccine Alfredo

1 pound uncooked fettuccine
4 tablespoons unsalted butter
4 garlic cloves, grated or pressed
1 tablespoon all-purpose flour
2 cups half and half
½ teaspoon fine sea salt
Pinch of ground nutmeg
Pinch of white pepper
1 cup freshly grated Parmesan cheese
Finely chopped fresh parsley, for garnish

Instructions

1. Cook the Pasta

Bring a large stockpot of well-salted water to a boil. Add fettuccine and cook until just al dente, according to package instructions. Reserve ½ cup of pasta water (optional), then drain and set aside.

2. Prepare the Chicken (Optional)

While the pasta cooks, season chicken breasts generously with salt and pepper. In a large nonstick skillet, heat olive oil over medium-high heat. Add chicken and sear for 4–6 minutes per side, or until fully cooked (internal temperature: 165°F). Transfer to a plate and let rest for 5–10 minutes before slicing.

3. Make the Alfredo Sauce

In the same skillet, melt butter over medium heat. Add garlic and sauté for about 1 minute, stirring frequently. Whisk in flour and cook for another minute to form a light roux. Gradually whisk in the half and half, salt, nutmeg, and white pepper. Cook, whisking constantly, until the sauce thickens and just starts to simmer.

4. Add the Cheese

Turn off the heat and immediately stir in the Parmesan cheese until smooth. Taste and adjust seasoning if needed.

5. Combine and Toss

Add drained pasta to the sauce and toss until evenly coated. If the sauce is too thick, stir in a bit of the reserved pasta water to loosen.

6. Serve

Plate the pasta with sliced chicken on top (if using), and garnish with chopped parsley and extra Parmesan. Serve immediately.

FAQs

Can I use heavy cream instead of half and half?
Yes—this will make the sauce even richer.

Why did my sauce get too thick?
Just whisk in a little reserved pasta water or milk to loosen it up.

Can I reheat leftovers?
Yes, but do so gently over low heat with a splash of milk to prevent the sauce from separating.

Is Alfredo the same as carbonara?
No. Alfredo uses a creamy cheese-based sauce, while carbonara contains eggs, cheese, and pancetta.

Serving

Serve this dish hot with garlic bread or a crisp green salad.
Pair it with a glass of dry white wine like Chardonnay or Pinot Grigio.
Top with extra cracked pepper and a sprinkle of lemon zest for brightness.

Suggestions

Double the sauce if you love extra-creamy pasta.
Freeze the sauce separately (without pasta) for future meals.
