Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with non-stick cooking spray.
Bring a pot of water to a boil. Season with salt and pepper. Add the chicken breasts and simmer until tender. Shred the cooked chicken for the casserole.
Boil pasta according to the package instructions. Ensure it’s slightly undercooked as it will finish in the oven. Drain and set aside.
Sauté Onion and Garlic:
In a skillet, sauté chopped onion and minced garlic in butter until softened and aromatic.
Prepare Soup Mixture:
In a bowl, mix both cans of soup without diluting with water. Set aside.
Spray the prepared baking dish with cooking spray. Begin layering with a portion of the cooked pasta at the bottom.
Follow this sequence for the layers: pasta, shredded chicken, sautéed onion mix, shredded cheddar cheese, and a layer of the soup mixture. Repeat until all ingredients are used, finishing with a layer of cheese on top.
Pour Chicken Broth:
Pour 1 to 1-1/2 cups of chicken broth over the top of the casserole to keep it moist during baking.
Cover the baking dish with foil and bake in the preheated oven for approximately 35-45 minutes or until the casserole is heated through and bubbly.
Uncover and Brown:
Uncover the casserole and bake for an additional 10 minutes or until the top is golden brown.
Remove from the oven and let it rest for a few minutes. Serve warm, and enjoy your delicious and creamy Chicken Tetrazzini!
