What You’ll Need (Ingredient Highlights)
Chicken breasts soak up the balsamic herb marinade and stay juicy after grilling.
Fettuccine is the perfect pasta shape for holding onto a creamy Alfredo sauce.
Heavy cream, milk, and butter create the rich base that makes the sauce smooth and luxurious.
Freshly grated Parmesan melts better than pre-shredded cheese and gives the sauce its classic flavor.
Fresh parsley brightens the finished dish and balances the richness.
Pro Tips Before You Start
Marinate the chicken for at least 3 hours so the herbs and garlic can fully flavor the meat.
Use freshly grated Parmesan for the smoothest sauce.
Reserve some pasta water before draining so you can loosen the sauce if needed.
Let the grilled chicken rest before slicing to keep it tender and juicy.
How to Make Grilled Chicken Fettuccine Alfredo
Step 1 – Marinate the chicken
Combine olive oil, balsamic vinegar, herbs, garlic, salt, black pepper, and red pepper flakes in a bowl or zip-top bag.
Add the chicken breasts, coat well, and refrigerate for at least 3 hours.
Step 2 – Prepare the grill
Heat the grill on high for about 15 minutes until very hot.
Lightly oil the grates with vegetable oil to prevent sticking.
Step 3 – Start the Alfredo base
In a heavy-bottomed saucepan, combine the butter, 1 cup heavy cream, and whole milk over medium heat.
Let it simmer gently for about 20 minutes until reduced and concentrated.
Step 4 – Grill the chicken
Place the marinated chicken on the hot grill and cook for 6 to 8 minutes on the first side.
Flip and cook for about 5 minutes more, or until the internal temperature reaches 165°F.
Step 5 – Rest the chicken
Transfer the chicken to a cutting board and loosely tent with foil.
Let it rest for 15 minutes before slicing.
Step 6 – Cook the pasta
Bring a large pot of salted water to a boil and cook the fettuccine until al dente.
Reserve 1/4 cup pasta water, then drain and return the pasta to the pot off the heat.
Step 7 – Finish the Alfredo sauce
Return the reduced cream mixture to medium heat and stir in the remaining 1/2 cup heavy cream, salt, and black pepper.
Remove from heat, then stir in Parmesan and nutmeg until smooth and silky.
Step 8 – Toss the pasta
Add a little reserved pasta water to the sauce, then pour the sauce over the cooked fettuccine.
Toss gently until the noodles are evenly coated, adding more pasta water if needed.
Step 9 – Slice and serve
Slice the rested chicken against the grain into strips or bite-sized pieces.
Top the Alfredo pasta with grilled chicken, parsley, and extra black pepper, then serve immediately.
What to Serve Them With
Serve this pasta with garlic bread for a classic pairing.
A crisp green salad with a light vinaigrette helps balance the richness.
Roasted broccoli or asparagus also works well on the side.
Variations / Substitutions
Use penne or linguine if you do not have fettuccine.
Swap chicken breasts for boneless chicken thighs for a juicier option.
Add sautéed mushrooms or spinach for extra flavor and color.
Use Italian seasoning if fresh mixed herbs are not available.
Storage & Leftovers
Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheat gently on the stovetop or in the microwave with a splash of milk or cream to loosen the sauce.
This dish is best enjoyed fresh, but leftovers can still be very good when reheated carefully.
