While the pasta cooks, heat olive oil in a large skillet over medium heat.
Season the chicken with salt and pepper, then add it to the skillet.
Cook the chicken for about 5-7 minutes per side, or until fully cooked through.
Add minced garlic to the skillet, cooking for 1-2 minutes until fragrant.
Pour in the heavy cream and simmer for a few minutes.
Stir in the grated Parmesan cheese until melted and well combined.
If the sauce is too thick, add a bit of reserved pasta water to reach desired consistency.
Toss the cooked fettuccine in the sauce until well coated.
Slice the cooked chicken and serve it over the pasta.
