Ingredients
  

For the Chicken:
  • 2 boneless skinless chicken breasts (about 1 pound total)
  • 1 tablespoon olive oil
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon dried Italian seasoning
  • Salt and black pepper
For the Greek Yogurt Alfredo Sauce:
  • 1 tablespoon butter
  • 3 cloves garlic minced
  • 1/2 cup low-sodium chicken broth
  • 1 cup plain Greek yogurt full-fat or 2% recommended
  • 3/4 cup Parmesan cheese freshly grated
  • 1/3 cup 2% milk
  • 1 teaspoon dried Italian seasoning
  • 1/4 teaspoon nutmeg
  • Salt and black pepper to taste
For the Pasta:
  • 8 ounces fettuccine or any pasta you prefer
  • Reserved pasta water about 1/2 cup
  • Optional Toppings:
  • Fresh parsley chopped
  • Extra grated Parmesan
  • Red pepper flakes
  • Cracked black pepper
  • A squeeze of lemon

Method
 

  1. Step 1: Cook the Pasta
  2. Bring a large pot of salted water to a boil. Cook the fettuccine according to the package directions until al dente. Before draining, scoop out about 1/2 cup of the starchy pasta water and set it aside — this is your secret weapon for getting the sauce to the perfect consistency. Drain the pasta and set aside.
  3. Step 2: Season and Cook the Chicken
  4. While the pasta is cooking, slice each chicken breast in half horizontally to create thin, even cutlets. This ensures they cook quickly and evenly. Season both sides with olive oil, garlic powder, Italian seasoning, salt, and pepper.
  5. Heat a large skillet over medium-high heat. Add the chicken and cook for 3-4 minutes per side until golden brown and cooked through — the internal temperature should reach 165°F. Remove the chicken from the skillet and let it rest for a few minutes before slicing.
  6. Step 3: Build the Sauce
  7. This is where the magic happens. Using the same skillet (all those browned bits from the chicken add incredible flavor), reduce the heat to medium. Add the butter and let it melt. Add the minced garlic and cook for about 30 seconds — just until fragrant. Don't let it brown.
  8. Pour in the chicken broth and use a spoon or spatula to scrape up any browned bits from the bottom of the pan. This is called deglazing, and it adds a depth of flavor you won't get any other way.
  9. Step 4: Add the Greek Yogurt (the Right Way)
  10. This is the most important step. Reduce the heat to low before adding the yogurt. If the pan is too hot, the yogurt will curdle.
  11. In a small bowl, stir a few spoonfuls of the hot broth from the pan into the Greek yogurt. This is called tempering — it gradually raises the temperature of the yogurt so it doesn't seize up when it hits the pan. Once the yogurt is warmed, pour it into the skillet and stir until smooth.
  12. Add the milk, grated Parmesan, Italian seasoning, nutmeg, salt, and pepper. Stir gently until the cheese is fully melted and the sauce is creamy and smooth. It should coat the back of a spoon.
  13. Step 5: Bring It All Together
  14. Add the cooked fettuccine and sliced chicken to the sauce. Toss everything gently to coat. If the sauce feels too thick, add the reserved pasta water one tablespoon at a time until you reach your desired consistency.
  15. Step 6: Serve
  16. Plate the chicken alfredo and top with fresh chopped parsley, extra grated Parmesan, red pepper flakes, and cracked black pepper. A small squeeze of lemon over the top adds a bright, fresh note that cuts through the richness beautifully.
