Ingredients Overview

Each ingredient in this recipe plays a special role in bringing the dish together into a mouthwatering experience:

Spaghetti (1 lb): The foundation of this dish. Its delicate yet firm texture allows it to hold up well under the creamy sauce and juicy chicken.
Cooked and Shredded Chicken (2 cups): A great way to use leftover rotisserie chicken, or you can cook up a couple of chicken breasts just for this dish. The chicken adds a hearty and savory element that pairs wonderfully with the cheese and veggies.
Cream of Chicken Soup (1 can): The key to a luscious and creamy sauce without needing to make one from scratch. This soup gives the dish that rich, comforting base that melds everything together.
Milk (1 cup): A splash of milk helps thin out the soup while keeping the sauce creamy and velvety.
Shredded Cheddar Cheese (2 cups): Cheddar adds a sharp, tangy flavor that complements the chicken and veggies, while also giving the bake that golden, bubbly finish.
Mixed Veggies (2 cups): Feel free to customize here! I love the mix of broccoli, bell peppers, and peas. The veggies bring in some fresh, crunchy texture and balance the richness of the dish.
Salt and Pepper to Taste: Seasoning is crucial to ensure all the flavors pop. Always taste and adjust.

Step-by-Step Cooking Instructions

Step 1: Preheat Your Oven to 350°F
Get your oven nice and hot so it’s ready to bake your casserole to golden, cheesy perfection.

Step 2: Cook the Spaghetti
Boil a pot of salted water and cook the spaghetti according to the package instructions until it’s al dente. This ensures your pasta stays firm even after baking. Drain and place the cooked spaghetti in a large mixing bowl.

Step 3: Prepare the Creamy Chicken Mix
In the mixing bowl with the spaghetti, add the shredded chicken, cream of chicken soup, milk, 1 cup of shredded cheddar cheese, and your mixed veggies. Give everything a generous sprinkle of salt and pepper, then stir well. Make sure every strand of spaghetti is coated in that creamy, cheesy goodness.

Step 4: Transfer to a Baking Dish
Lightly grease your favorite baking dish (a 9×13 pan works beautifully). Transfer the spaghetti mixture into the dish and spread it out evenly, making sure the veggies and chicken are distributed throughout.

Step 5: Add the Cheese Topping
Sprinkle the remaining 1 cup of shredded cheddar cheese over the top of the casserole. This will create a bubbly, crispy layer that everyone loves.

Step 6: Bake Until Perfection
Cover the baking dish with foil and bake for 30 minutes. After 30 minutes, remove the foil and bake for another 10 minutes, or until the cheese on top is melted and golden brown.

Step 7: Serve & Enjoy!
Let your cheesy chicken spaghetti bake cool for a few minutes before serving. Dig in and enjoy the melty, creamy deliciousness!

Storage and Reheating Tips

Storage:
If you have leftovers (lucky you!), let the casserole cool completely before transferring it to an airtight container. Store in the fridge for up to 3 days.

Reheating:
Reheat individual portions in the microwave by covering them with a damp paper towel and heating in 30-second intervals until warm. For a crispier top, reheat larger portions in the oven at 350°F for about 10-15 minutes, uncovered.

Freezing:
This dish also freezes well. Simply wrap the entire baking dish tightly with plastic wrap and aluminum foil before baking, and freeze for up to 2 months. To cook, thaw overnight in the fridge and then bake as instructed.
