Chicken Alfredo

Chicken Alfredo is pasta coated in a silky butter and cream sauce with Parmesan cheese and topped with sliced chicken breast. The sauce comes together in minutes and clings to every strand of noodle, making it rich and satisfying without being heavy.

Ingredients for Chicken Alfredo

Fettuccine is the traditional cut for this dish because its wide, flat surface catches and holds the sauce. Butter and heavy cream form the base of the sauce, while Parmesan cheese grated from a block thickens it and adds sharp, salty flavor. Garlic brings depth without overpowering. Salt and black pepper season the sauce and the pasta water. Chicken breast is cooked separately, sliced, and laid on top so it stays tender and juicy. A splash of pasta cooking water loosens the sauce to the right consistency and helps it coat the noodles evenly.

Why This Chicken Alfredo Works

The sauce is an emulsion of fat and starch that clings to pasta. Butter melts and cooks out its water, garlic flavors the fat, and cream adds richness. When you stir in grated Parmesan, the cheese melts into the hot liquid and thickens it into a glossy coat that won’t separate or break.

Starchy water from the pasta is key. When you toss the hot noodles with the sauce and a few tablespoons of cooking water, the starch helps bind everything together and keeps the sauce from getting thick and gluey as it cools. The sauce should move easily around the pasta, not cling in clumps.

Chicken breast is cooked in a separate skillet until it reaches a safe temperature, then sliced and laid on top. This way it stays moist and tender instead of getting tough in the sauce.

Mistakes To Avoid

Overcooking the pasta before the sauce is ready makes it mushy and unable to hold the sauce. Cook it to al dente, stopping just before it feels fully soft when you bite it. If it’s overcooked, the noodles absorb too much water and fall apart when you toss them.

Using pre-shredded cheese instead of a block creates a grainy, broken sauce. The starch on shredded cheese prevents it from melting smoothly into the cream, leaving visible specks and a dull texture instead of a glossy coat.

Letting the cream and cheese sit on high heat without stirring causes the sauce to break and separate into greasy puddles. Keep the heat at medium and stir constantly so the cheese melts evenly and stays emulsified with the cream and butter.

Adding cold cream or cheese straight from the refrigerator drops the temperature of the sauce and causes it to seize. Warm the cream in the pan with the butter and garlic for a minute before adding the cheese, so everything stays smooth.

Ingredients

• 1 pound fettuccine
• 1 pound boneless, skinless chicken breast
• Salt
• Black pepper
• 6 tablespoons butter
• 4 cloves garlic, minced
• 1 1/2 cups heavy cream
• 1 1/2 cups Parmesan cheese, grated from a block
• 2 tablespoons pasta cooking water

Step-by-step Instructions

1. Bring a large pot of salted water to a rolling boil over high heat, about 8 to 10 minutes.
2. While water heats, season the chicken breast on both sides with salt and pepper.
3. Heat a 12-inch skillet over medium-high heat for 1 minute, then add the chicken breast and cook for 6 to 7 minutes on the first side until golden brown.
4. Flip the chicken, reduce heat to medium, and cook for 5 to 6 minutes more until an instant-read thermometer inserted in the thickest part reads 165°F (74°C), with no pink inside.
5. Transfer the chicken to a cutting board and let it rest for 3 minutes, then slice it into 1/2-inch-thick strips.
6. Add fettuccine to the boiling water and cook for 1 minute less than the box time, stirring occasionally so it does not stick, until just shy of fully tender.
7. Reserve 1/2 cup of pasta cooking water, then drain the pasta in a colander.
8. In the same skillet used for chicken (no need to wash it), melt butter over medium heat, add minced garlic, and cook for 30 seconds until fragrant but not brown.
9. Pour in the heavy cream and warm it for 1 minute, stirring often, until it steams and small bubbles form at the edges.
10. Remove the skillet from heat and stir in the grated Parmesan in two additions, stirring until each addition melts completely and the sauce is smooth and glossy.
11. Add the drained pasta to the sauce and toss gently for 1 minute, then add 2 tablespoons of pasta cooking water and toss again, adding more water 1 tablespoon at a time if needed until the sauce flows freely and coats every noodle without pooling.
12. Divide the pasta among four bowls or plates, top each with sliced chicken, and serve right away.
