Cook the pasta: Boil pasta in salted water until al dente. Drain and set aside, reserving a bit of pasta water.
Cook the chicken: Heat olive oil in a skillet. Season chicken with salt and pepper, then cook for 6–7 minutes until golden and fully cooked. Remove and set aside.
Make the creamy pesto sauce: In the same skillet, melt butter and sauté garlic until fragrant. Add heavy cream, Parmesan, and pesto. Stir until the sauce becomes thick and creamy.
Combine pasta and chicken: Add the cooked pasta and chicken into the sauce. Toss gently to coat everything evenly, adding a splash of pasta water if needed for consistency.
Serve and garnish: Top with fresh basil, grated Parmesan, and a few drops of lemon juice. Serve warm and enjoy your creamy Italian masterpiece! 🇮🇹🍽️
