Combine all ingredients in a bowl and pour into a 9 x 13, lightly greased casserole dish. Bake at 350 degrees for 40-50 minutes or until set.

Melt butter in a saucepan over medium heat. Whisk in flour and cook for 2 minutes. Gradually whisk in chicken stock. Reduce heat to low and cook and stir until thick enough to coat the back of a spoon, 4-6 minutes.

Stir in heavy cream, and season with salt, pepper, and cayenne pepper.

Serve the casserole with gravy over the top and a big side of mashed potatoes. And Enjoy!
