• 1 lb boneless, skinless chicken breasts (2 medium, about 8 oz each)
• 3/4 tsp kosher salt
• 1/2 tsp freshly ground black pepper
• 1 tsp Italian seasoning (or 1/2 tsp dried oregano + 1/2 tsp dried basil)

• 4 qt water
• 1 tbsp kosher salt (for the pasta water)

For the Alfredo Sauce & Finish

• 1 tbsp olive oil
• 1 tbsp unsalted butter
• 4 garlic cloves, minced (about 1 1/2 tbsp)
• 1 cup heavy cream
• 1 cup whole milk
• 1 cup (3 oz) finely grated Parmesan cheese, plus more for serving
• 1/4 tsp freshly grated nutmeg (optional)
• 1/4 tsp red pepper flakes (optional)
• 1 tsp finely grated lemon zest, plus more for garnish

• 2 tbsp chopped fresh flat-leaf parsley, plus more for serving
• Freshly ground black pepper, to finish
• 1/2 to 1 cup reserved pasta cooking water, as needed

Step-by-Step Instructions

Step 1: Prep your pot and ingredients

Fill a large pot with 4 qt water and bring to a boil. Measure 1 tbsp kosher salt for the pasta water (do not add yet). Finely grate the Parmesan, mince the garlic, chop the parsley, and zest the lemon before juicing it. Having everything ready makes the sauce come together smoothly.

Step 2: Season the chicken

Pat the chicken dry with paper towels. Season all over with 3/4 tsp kosher salt, 1/2 tsp black pepper, and 1 tsp Italian seasoning. Let it sit at room temperature while you heat the pan (5 minutes) to promote even cooking.

Step 3: Sear the chicken to juicy perfection

Heat a 12-inch skillet over medium-high heat. Add 1 tbsp olive oil and 1 tbsp butter. When the butter foams, add the chicken and sear 4–5 minutes per side until deep golden and the thickest part reads 165°F on an instant-read thermometer. Transfer to a board and rest 5–10 minutes to keep the juices in.

Step 4: Start the pasta

Salt the boiling water with the reserved 1 tbsp kosher salt. Add the fettuccine and cook until al dente, 9–10 minutes (check package). Before draining, scoop out 1 cup of the starchy pasta water. Drain the pasta and keep it handy.

Step 5: Build a fragrant garlic-butter base

Return the skillet to medium heat and add 1 tbsp olive oil and 1 tbsp butter. Stir in the minced garlic and cook just until fragrant, 30–60 seconds, avoiding browning. The gentle heat releases sweet garlic flavor without bitterness.

Step 6: Simmer cream, then emulsify with Parmesan

Pour in 1 cup heavy cream and 1 cup milk. Bring to a gentle simmer and cook 3–4 minutes, stirring. Reduce heat to low. Sprinkle in the Parmesan a small handful at a time, whisking constantly until the sauce is smooth and silky. Season with a pinch of nutmeg and red pepper flakes, if using. If the sauce seems very thick, whisk in 2–4 tbsp reserved pasta water to loosen; you’ll adjust more with the pasta.

Step 7: Toss pasta and finish with lemon and pepper

Add the drained fettuccine to the skillet and toss vigorously 1–2 minutes until every strand is coated and glossy, adding more reserved water as needed (up to 1/2 cup total). Off heat, stir in 1 tsp lemon zest and 1 tbsp lemon juice. Slice the rested chicken crosswise into 1/2-inch strips and fold most into the pasta, reserving a few slices for topping.

Step 8: Plate and serve

Twirl the pasta into warm bowls, top with reserved chicken slices, and shower with extra Parmesan, chopped parsley, and lots of freshly cracked black pepper. Add a final sprinkle of lemon zest if you like. Serve immediately while the sauce is luxuriously smooth.

Pro Tips

• Use freshly grated Parmesan (microplane or fine holes). Pre-shredded cheese can make the sauce grainy.
• Keep the sauce just at a low simmer when adding cheese; high heat can cause clumping or separation.
• Reserved pasta water is your secret weapon. Add it gradually until the sauce becomes glossy and clings to the noodles.
• Let the chicken rest before slicing to keep it juicy and to avoid watering down the sauce.
• Finish with lemon zest and black pepper off heat to preserve aroma and brightness.

Variations

• Broccoli Alfredo: Blanch 2 cups small broccoli florets in the pasta water during the last 2 minutes of cooking; toss with the pasta.
• Shrimp Alfredo: Swap chicken for 1 lb large shrimp, seared 1–2 minutes per side until pink and opaque.
• Mushroom Spin: Sauté 8 oz sliced cremini mushrooms after the garlic until browned; continue with the cream and cheese.

Storage & Make-Ahead

Fettuccine Alfredo is best enjoyed right away. If you must store, refrigerate leftovers in an airtight container for up to 3 days. Reheat gently on the stovetop over low heat with a splash of milk or cream and a spoonful of water to loosen, stirring until smooth—avoid boiling. Cook chicken up to 1 day ahead and slice just before serving. Pasta can be cooked 1 day ahead; toss with 1 tsp olive oil to prevent sticking and rewarm in the sauce with additional pasta water. Freezing is not recommended.
