How to make chicken spaghetti casserole

Preheat oven to 400 degrees Fahrenheit.

In a 12-inch saute pan, melt 2 tablespoons of butter over medium heat.

Add diced onion to the pan and sweat for a few minutes, seasoning with salt and pepper.

Add 1 tablespoon of chopped garlic and cook until fragrant.

Add the diced bell peppers and sweat for about 2 minutes.

In a large mixing bowl, combine the cooked noodles, 20 ounces of cream of mushroom soup, 2 pounds of rotisserie chicken, and 4 cups of cheese (reserve 1.5 cups for topping).

Mix everything thoroughly until well incorporated.

Transfer the mixture to a 9x13 baking dish, pressing it down to eliminate air pockets.

Top with the reserved cheese and spread evenly.

Bake in the preheated oven for 20 minutes.
