Rice and Green Chile Casserole

Why I Love This Recipe
This recipe came from a customer of mine when i worked at a local bank when i was 16 years old. I have used this recipe everytime that I make mexican food. Everyone who has tried this always wants the recipe.
Ingredients You'll Need
1 cup uncooked rice
1 stick of butter
1 large onion diced
2 cups chicken stock
1 large can diced green chile peppers
1 8 oz. pkg shredded cheese ( I use a mexican blend)
1/2 pint of whipping cream.
Directions
In a sauce pan melt the stick of butter then sautee the onion and rice in the butter until rice starts to change color slightly. Add the chicken stock, bring to a boil and then turn down to simmer covered with lid for 20 minutes until rice is done.
Using at least a 4 inch deep round casserole dish lightly sprayed or greased, alternating a layer of cooked rice mixture, a layer of green chiles, a layer of cheese. Continue layering until casserole dish is full, or all your ingredients are used, with the last layer being cheese on the top.
Pour the 1/2 pint of whipping cream over the top of the casserole.
Bake at 375 45 minutes or until hot a bubbly
