Creamy Baked Spinach

This is a recipe I found in a Paula Deen magazine that I've made several times since I first saw it. Its so easy and so good. But unfortunately not so good for you...

What You Need:
2 tablespoons butter
1/2 chopped onion (try using frozen chopped onion for this)
2 tablespoons flour
3/4 cup half and half (divided)
10 oz package of frozen chopped spinach, thawed and drained (however last time i used a 9 oz bag of fresh spinach and chopped it - either works)
1 cup shredded swiss cheese
1/2 teaspoon salt
1/4 teaspoon pepper
1/4 teaspoon nutmeg (I always skip this part bc i dont like the sweet taste mixed in. But if you like nutmeg, go for it.)

What You Need To Do:
Preheat Broiler. Spray 2 ramekins with Pam. In a medium skillet, melt butter over medium heat. Add onion, cook 5 minutes or until tender. (If using fresh spinach, add it in now so it has time to wilt). Add flour and cook 2 minutes, stirring constantly. Stir in 1/4 cup half and half. Stir until smooth. Stir in Spinach, cheese, salt, pepper, nutmeg and remaining half and half. Spoon into baking dishes. Broil 5 inches from heat for two minutes or until hot and bubbly. Serve immediately.
