- Bring a large pot of salted water to a rolling boil.

- Add the bite-sized chicken pieces to the hot skillet in a single layer.
- Season the chicken with a pinch of salt and black pepper.

- Add the minced garlic to the skillet and cook for 1 minute until fragrant.
- Pour in the 1/2 cup of chicken broth to deglaze the pan, scraping up any browned bits from the bottom.
- Stir in the 1/2 cup of heavy cream and 1 cup of basil pesto until the sauce is well combined and heated through.
- Remove the skillet from the heat.
- Add the cooked, drained spaghetti to the skillet with the pesto chicken sauce.
- Toss everything together until the spaghetti is evenly coated.
- Transfer the entire mixture to a 9×13 inch baking dish, spreading it into an even layer.
- Sprinkle the 1 cup of shredded mozzarella and 1/2 cup of grated Parmesan cheese evenly over the top.
- Bake in the preheated 375°F oven for 15-20 minutes, until the cheese is melted and bubbly with golden spots.
- Let the casserole rest for 5 minutes before serving to allow it to set.
Creamy, cheesy, and packed with herby pesto flavor, this casserole has a wonderfully satisfying texture from the tender pasta and juicy chicken. The crispy, golden cheese top provides a perfect contrast to the rich interior. For a fresh twist, serve it with a simple arugula salad dressed with lemon vinaigrette to cut through the richness.
