Instructions

Cook the Pasta: Boil salted water in a large pot. Add pasta and cook until al dente, about 8 minutes. Drain the pasta thoroughly and set it aside to keep warm.
Sauté Aromatics: In a large skillet over medium heat, melt the butter. Add the finely chopped onion and minced garlic, and sauté until they are soft and fragrant, about 3 to 5 minutes.
Cook Chicken: Dice the chicken breasts into bite-sized pieces and add them to the skillet with the onions and garlic. Cook over medium heat until the chicken pieces are golden brown and cooked through, about 7 to 10 minutes.
Create Sauce: Stir in the cream of mushroom soup and chicken broth into the skillet. Mix well to combine all ingredients evenly and let the sauce simmer for a few minutes to meld the flavors.
Combine: Gently fold the cooked pasta and frozen peas into the sauce mixture, ensuring everything is evenly coated with the creamy sauce. Season with dried Italian herbs, salt, and pepper to taste.
Bake: Preheat the oven to 350°F (175°C). Transfer the pasta and chicken mixture to a greased baking dish. Sprinkle the top evenly with shredded mozzarella and grated Parmesan cheese. Bake uncovered for 25 to 30 minutes until the cheese is bubbly and lightly golden brown.

Notes

Use freshly grated Parmesan for the best flavor and melting quality.
For an extra creamy dish, add a splash of heavy cream or half-and-half to the sauce before baking.
Frozen peas add a nice sweetness and pop of color but can be substituted with cooked green beans or broccoli.
Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven to maintain the cheesy crust.
Make sure the chicken is fully cooked before baking to avoid undercooked poultry.
