Begin by seasoning the chicken breasts generously with salt and pepper on both sides.
In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Once hot, add the chicken breasts and cook for about 6-7 minutes per side, or until golden brown and cooked through. Remove the chicken from the skillet and set it aside.
In the same skillet, add the minced garlic and sauté for about 30 seconds, until fragrant.
Add the halved cherry tomatoes to the skillet and cook for about 3-4 minutes, until they start to soften.
Pour in the heavy cream and add the Italian seasoning. Stir well, bringing the mixture to a gentle simmer.
Stir in the grated Parmesan cheese until fully melted and the sauce thickens slightly.
While the sauce is simmering, cook the pasta according to package instructions until al dente. Drain and set aside.
Slice the cooked chicken into strips and place it back in the skillet with the sauce, letting it warm through for a minute.
Add the cooked pasta to the skillet and toss everything together until the pasta is coated in the creamy sauce, chicken, and tomatoes.
Serve immediately, garnished with fresh basil leaves for a fragrant finish.
