Ingredients

10 oz spaghetti cooked
2 cups chicken shredded
1 clove garlic minced
½ green bell pepper chopped
1 teaspoon Italian seasoning
2 tablespoons butter
¼ cup flour
½ cup chicken broth
½ cup milk
¼ cup heavy whipping cream
14 oz diced tomatoes drained
1 ½ cups mozzarella
salt and pepper to taste

Instructions

Preheat the oven to 375°F.
Cook the spaghetti according to the package instructions until al dente and still slightly firm. Drain and set aside.
In a large skillet over medium high heat, cook the garlic and bell pepper in the butter until tender. Stir in the lour and Italian seasoning and cook for 1 minute more.
Stir in the heavy whipping cream, broth and milk. Bring the pan to a boil, reduce the head and simmer until it begins to thicken.
Remove the pan from the heat and stir in ½ cup of mozzarella until combined. Season with salt and pepper.
Stir the spaghetti, chicken, and diced tomatoes into the pan. Spread the mixture into a lightly greased 9 x 13” baking dish.
Top with the remaining mozzarella and bake for 15 - 20 minutes, until the edges are lightly browned and the cheese is bubbly.

Notes

Make sure to use enough water to cook the pasta, so that when the pasta expands, there's room for the noodles to move freely.
You can substitute a rotisserie chicken for cooking your own chicken breasts to save time.
If freezing, line your dish with parchment paper and let it freeze solid, then transfer to a large freezer bag. This frees up your casserole dish.
You can make this with other pastas that you have on hand such as fettuccine or large pasta noodles like penne or ziti.
