Instructions

Preheat the Oven: Preheat your oven to 425°F (220°C) to prepare for baking the casserole evenly.
Combine Ingredients: In a large baking dish, mix the uncooked rotini pasta, Alfredo sauce, chicken stock, shredded chicken, and minced garlic thoroughly to ensure even distribution of flavors.
First Bake: Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 30 minutes to cook the pasta partially and meld the flavors.
Check and Stir: Remove the foil and stir the pasta well. Check the doneness of the pasta – it should be almost al dente but still firm and with some liquid remaining. If it’s still very hard, re-cover and bake for up to an additional 10 minutes until the pasta is al dente.
Add Cheese: Sprinkle the shredded mozzarella cheese evenly over the top of the pasta mixture.
Final Bake: Bake uncovered for another 5-10 minutes until the cheese melts and the pasta reaches perfect al dente texture without becoming mushy.
Garnish and Serve: Optionally, garnish with freshly grated Parmesan cheese and chopped fresh herbs such as basil, oregano, or parsley before serving for added flavor and presentation.

Notes

This dish requires only about 10 minutes of preparation, making it a quick and convenient meal.
All ingredients cook together in one baking dish, minimizing cleanup.
If pasta isn’t sufficiently cooked after the initial 30-minute bake, simply cover and bake longer in 5-10 minute increments until nearly al dente before adding cheese.
Use rotisserie chicken for convenience, or substitute with any cooked diced chicken.
Fresh herbs enhance flavor and appearance but are optional.
