Cheddar Chicken Spaghetti

Pimentos and green chilies combine with cheddar cheese and tarragon to give Cheddar Chicken Spaghetti casserole its unique flavor. Tarragon is one of my favorite herbs to combine with chicken as the flavors complement each other so well.

The casserole freezes well so if you want to double up on the recipe, it’s a good dish to stock the freezer. I like this recipe because not only can I make extra for the freezer, I can easily make a vegetarian option by substituting broccoli or red bell peppers in place of the chicken (I substitute cream of celery soup for the vegetarian version).

  1. I forgot to get pimentos so I added bacon bits. Easy, fast and flexible recipe that tastes delicious ?

    • Thanks for the feedback – so glad you enjoyed it! I actually made a vegetarian version yesterday and had it for dinner last night and lunch today. 🙂
