Smoky grilled chicken adds bold flavor
Ready in 30 minutes
Easily customizable with veggies or spice blends
Key Ingredients
Chicken Breasts — Use skinless breasts and flatten them slightly for even cooking. Season with salt, pepper, or your favorite spice blend.
Fettuccine Pasta — A classic choice. Its wide noodles hold onto the sauce beautifully.
High-quality Butter — This is the base of the sauce. Dice it so it melts evenly.
Parmesan Cheese — Freshly grated parmesan cheese only. Pre-shredded won’t melt right and can make the sauce gritty.
Pasta Water — The secret to silky Alfredo. Reserve a little before draining.
Substitutions
No fettuccine? Tagliatelle or linguine will work too. Just avoid thin pasta like angel hair, which doesn’t hold the sauce as well.
Want to add veggies? Toss in steamed broccoli, peas, or roasted red peppers. It’s a great way to bulk it up.
How to Make Grilled Chicken Alfredo from Scratch
Prepare the chicken. Flatten the breasts if needed (see notes), and season with salt and pepper (or your favorite seasoning blend). Hold off on the oil until it’s time to grill.
Grill the chicken. Preheat the grill to medium heat using a 2-zone setup: bank the hot coals to one side and clean the grates. Just before grilling, brush the chicken with olive oil and place it over the hot side. Grill for about 3–4 minutes per side, flipping carefully to avoid tearing.
Once you have solid char marks, move the chicken to the cooler side and let it finish cooking indirectly until it reaches an internal temperature of 160°F. Remove and rest, lightly tented with foil.
Cook the pasta. You can get the water boiling while the chicken hits the grill. Cook the pasta in salted water according to the package instructions until al dente. Drain the pasta but reserve about ½ cup of the pasta water.
Make the Alfredo sauce. Add the butter and Parmesan cheese to a large pan or skillet. Using tongs, transfer the freshly cooked, hot pasta directly into the pan. Pour in about half of the reserved pasta water and gently toss the pasta – this will melt the butter and cheese, forming a creamy sauce. Want it richer? Add more cheese. Too thick? Splash in more pasta water. Adjust to your liking.

Top Tips
Pull the chicken at around 160°F. Chicken breasts keep cooking after they come off the grill. Take them off at 160°F and let them rest. This keeps them juicy and tender when you slice. Don’t worry, it’ll hit that safe 165°F while resting!
Grill extra chicken. Trust me, it disappears fast. Once that smoky, juicy chicken hits the Alfredo, everyone wants seconds.
Even out the chicken breasts. Uneven thickness means uneven cooking. Seal them in a plastic bag and gently pound the thick end with a heavy skillet or meat mallet. This helps prevent dry edges and undercooked centers.
Use freshly grated cheese. Pre-shredded cheese doesn’t melt properly and can make the sauce gritty. Go for Parmigiano Reggiano, which melts smoothly and delivers that rich, creamy texture without needing any cream.
Toss the pasta while it’s hot. Don’t wait around once the pasta’s drained. The heat is key to melting the butter and cheese into a silky sauce. Toss it fast for the best results.
Control the sauce with pasta water. Pasta water is your secret weapon. Add it a little at a time to loosen the sauce. Want it thicker? Add more cheese. You’re the boss of the texture.
How to Serve Grilled Chicken Alfredo
Slice the rested grilled chicken and serve it right on top of the Alfredo pasta. Garnish with more Parmesan and a sprinkle of chopped parsley. Serve it with garlic bread or a simple salad if you’re looking for sides, but this pasta can absolutely stand on its own. One of the best sides for this recipe is Grilled Broccoli Crunch Salad, which you can easily make alongside this recipe!
How to Store Leftovers
Grilled chicken can be stored in the fridge for up to four days. Alfredo sauce is best made fresh, but if you need to store it, keep the pasta and sauce separate if possible. Reheat gently with a splash of pasta water or milk and stir constantly to bring it back together.
Frequently Asked Questions
How do I grill chicken breasts without drying them out?
Pound the chicken to an even thickness and grill using a 2-zone setup to keep it juicy. Start with a good sear over high heat, then move the chicken to indirect heat until it reaches 160°F. Let it rest before slicing to lock in moisture.
Is this Alfredo recipe good for meal prep?
Grilled chicken Alfredo is best fresh, but the chicken can be prepped ahead. Store the grilled chicken separately and cook fresh pasta and Alfredo sauce when ready. Reheating the sauce can cause it to separate, so making it fresh only takes a couple of minutes.
What vegetables go in chicken Alfredo?

What’s the best cheese for Alfredo sauce?
The best cheese for Alfredo sauce is freshly grated Parmigiano Reggiano. It melts smoothly, adds rich umami flavor, and creates a creamy texture without clumping. Avoid pre-shredded cheese, which contains anti-caking agents that can make the sauce gritty.
