Cheesy Chicken Spaghetti Bake

by Laura

I am starting to transition toward fall meals now. I am so excited for next week. We are going to have a few days in the 70’s. I love this time of year. This cheesy chicken spaghetti bake is a perfect meal to enjoy while we transition to that fall weather.

As you can guess from the recipe title, there is cheese, chicken, and spaghetti involved. A nice trio of ingredients. You can also deduct that this recipe is baked in the oven.

The sauce for this recipe is a basic white sauce also known as a bechemel sauce. However, instead of milk, you use chicken broth and cream. Now, this is where the cheese come in. You mix in paremsan cheese and sharp cheddar cheese to the white sauce to make it a cheese sauce.

The casserole itself is then comprised of spaghetti, chicken, bell pepper, onion, tomatoes, Italian seasoning, and chilies. After it’s all combined you pour it onto a baking dish, top it with more cheese, and bake.

I have a feeling this dish will be one you will be making for years to come. So come on and give this cheesy chicken spaghetti bake a try.
