How to Prepare the Chicken
Here’s how to cook the chicken to golden, tender perfection:
- Season the Chicken: Drizzle each chicken breast with avocado oil and season both sides generously with salt, black pepper, garlic powder, paprika, Italian seasoning, and red chili flakes, rubbing the seasonings in evenly.
- Sear the Chicken: Heat a little avocado oil in a large skillet over medium-high heat until shimmering, then add the chicken and cook for 6-7 minutes on the first side until golden and crispy.
- Cook Through: Flip the chicken and cook for another 6-7 minutes on the second side until fully cooked through and the internal temperature reaches 165°F.
- Rest and Slice: Remove the chicken from the pan and let it rest for 2-3 minutes, then slice it into bite-sized pieces or leave whole.
Preparing the Fettuccine and Sauce
While the chicken rests, you can prepare the pasta and create the creamy lemon garlic sauce:
- Cook the Pasta: Bring a large pot of salted water to a boil and add the fettuccine, cooking according to package directions until al dente, usually 8-10 minutes.
- Reserve Pasta Water: Before draining, reserve about 1/2 cup of pasta water in a small bowl or measuring cup.
- Build the Base: In the same skillet used for the chicken, add 2 tablespoons of butter over medium heat and let it melt, then add the chopped onion and cook for 2-3 minutes until softened and fragrant.
- Add Garlic and Flour: Stir in the minced garlic and sauté for about 1 minute until very fragrant, then sprinkle in the flour and mix well, cooking for 1-2 minutes to create a light roux.
- Season the Sauce: Add black pepper, paprika, Italian seasoning, and red chili flakes to taste, stirring constantly for about 30 seconds to bloom the spices.
- Cream It Up: Pour in the heavy cream slowly while stirring to create a smooth, lump-free sauce, then reduce heat to low and let simmer for 2-3 minutes.
- Add Lemon and Cheese: Stir in the lemon juice and lemon zest, then gradually add the Parmesan cheese while stirring constantly until it melts completely and the sauce becomes silky.
- Combine Pasta: Add the cooked fettuccine to the sauce and toss gently until every strand is coated, adding splashes of reserved pasta water as needed to reach your desired sauce consistency.
- Finish with Herbs: Stir in the fresh chopped parsley just before serving.

Assembly: Bringing It All Together
Once your chicken and sauce are ready, it’s time to plate this elegant dish!
- Twirl the Pasta: Using tongs or a pasta fork, twirl a generous nest of lemon garlic fettuccine onto each serving plate or bowl.
- Top with Chicken: Arrange the sliced or whole chicken breast on top of the pasta, positioning it in the center.
- Garnish Generously: Sprinkle with freshly grated Parmesan cheese and fresh parsley over the top.
- Serve with Lemon: Place a fresh lemon wedge on the side of each plate for guests to squeeze additional brightness over their dish as desired.
Variations and Customizations
One of the great things about lemon garlic chicken fettuccine is its versatility!
- Add Vegetables: Sauté mushrooms, spinach, sun-dried tomatoes, or roasted asparagus in the pan before making the sauce for extra flavor and nutrition.
- Protein Swaps: Substitute the chicken with shrimp, scallops, or even baked firm tofu for a different take on this creamy pasta.
- Pasta Alternatives: Use linguine, pappardelle, or even spaghetti instead of fettuccine, or try whole wheat or gluten-free pasta for dietary preferences.
- Spice Level: Increase the red chili flakes for more heat, or add fresh red pepper flakes to the sauce just before serving.
- Lighter Version: Replace half the heavy cream with chicken broth or pasta water for a lighter, less rich sauce.
Serving Suggestions
Pair this creamy fettuccine with a crisp green salad dressed in a simple vinaigrette to balance the richness of the sauce.
A glass of dry white wine like Pinot Grigio or Sauvignon Blanc complements the bright lemon and garlic flavors beautifully.
For a complete meal, serve with warm garlic bread or crusty focaccia to soak up every drop of the silky sauce.

Recipe FAQ’s
Can I use chicken thighs instead of chicken breasts?
Yes, chicken thighs work wonderfully and stay even more tender and juicy, though they may need an extra 2-3 minutes of cooking time on each side.
What if I don’t have fresh lemon juice?
You can use bottled lemon juice in a pinch, though fresh lemon juice gives the best bright flavor and complexity to the sauce.
How can I store leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days and reheat gently on the stovetop with a splash of cream or pasta water to restore the sauce consistency.
