Grilled Chicken Fettuccine Alfredo (Creamy & Easy)

Introduction

Grilled Chicken Fettuccine Alfredo is the perfect combination of smoky, juicy grilled chicken and a luxuriously creamy Parmesan Alfredo sauce. The tender pasta is coated in a silky garlic cream sauce, while the grilled chicken adds depth of flavor and satisfying protein. This dish feels restaurant-worthy, yet it is surprisingly simple to prepare at home, making it ideal for both weeknight dinners and special occasions. Because the Alfredo sauce is made from scratch, you control the richness, seasoning and texture, ensuring every bite is perfectly balanced and incredibly comforting.

History and Background of the Recipe

Fettuccine Alfredo originated in Italy and was traditionally made with butter and Parmesan melted into hot pasta. However, modern versions often include cream for an ultra-smooth and velvety consistency. Grilling chicken and serving it on top of Alfredo pasta is a popular American-Italian adaptation that adds extra flavor and heartiness. As a result, this dish has become a true classic in restaurants and home kitchens alike, loved for its creamy texture and bold, savory taste.

Ingredients

12 oz fettuccine pasta
2 large boneless, skinless chicken breasts
2 tbsp olive oil
1 tsp garlic powder, divided
1 tsp onion powder
1/2 tsp smoked paprika
Salt and pepper to taste
4 tbsp unsalted butter
2 garlic cloves, minced
2 cups heavy cream
1 1/2 cups grated Parmesan cheese
1/4 tsp ground nutmeg, optional
Fresh parsley for garnish, optional

Preparation

Step 1: Season and grill the chicken

Rub the chicken breasts with 1 tablespoon of olive oil, 1/2 teaspoon garlic powder, onion powder, smoked paprika, salt and pepper. Preheat your grill to medium-high heat. Cook the chicken for 6 to 8 minutes per side until the internal temperature reaches 165°F (75°C). Let the chicken rest for 5 minutes, then slice it into strips.

Step 2: Cook the pasta

Bring a large pot of salted water to a boil. Add the fettuccine and cook until al dente according to package instructions. Drain the pasta, reserving about 1/2 cup of cooking water.

Step 3: Make the Alfredo sauce

In a saucepan, melt the butter over medium heat. Add the minced garlic and sauté gently for 1 to 2 minutes until fragrant. Pour in the heavy cream and simmer very gently for 3 to 4 minutes. Gradually whisk in the grated Parmesan until the sauce becomes smooth and thick. Season with salt, pepper and a pinch of nutmeg if using.

Step 4: Combine pasta and sauce

Add the cooked fettuccine to the sauce and toss well to coat. If the sauce seems too thick, stir in a splash of the reserved pasta water until you reach your preferred consistency.

Step 5: Serve with grilled chicken

Divide the creamy pasta into bowls and top with sliced grilled chicken. Garnish with fresh parsley and extra Parmesan cheese if desired. Serve immediately while hot and creamy.

Frequently Asked Questions

Can I use another type of pasta?
