01 - Bring a large pot of salted water to a boil. Cook the pasta according to the package instructions until al dente. Reserve 1/2 cup of pasta water, then drain and set aside.
02 - Season the chicken pieces with salt and black pepper evenly.
03 - In a large skillet, heat olive oil over medium-high heat. Add the chicken and cook for 5-7 minutes, stirring occasionally, until golden and cooked through. Remove chicken and set aside.
04 - In the same skillet, reduce heat to medium. Add minced garlic and sauté for 30 seconds until fragrant.
05 - Pour in the heavy cream, bring to a simmer, and cook for 2 minutes. Stir in the pesto and Parmesan cheese until smooth and combined.
06 - Return the cooked chicken to the skillet. Add the drained pasta and toss everything together, adding a splash of reserved pasta water if needed to loosen the sauce. Serve immediately, garnished with fresh basil and extra Parmesan.
