Place pie crust in pie plate. Crimp edges to make it pretty. I like to use a tart pan, but any pie plate will work.
In a skillet cook bacon, drain on a paper towel and crumble. Pour off most of bacon grease in skillet, but reserve about a teaspoon. Place broccoli florets in skillet and cook for about 2-3 minutes, just so they are not raw anymore.
In a large bowl, whisk eggs, cream, mayonnaise, garlic salt, onion powder and Dijon mustard. Add in the bacon, broccoli and 1 cup cheese.
Pour into prepared pie plate. Make sure the ingredients are dispersed evenly. Sprinkle remaining cheese on top.
Bake 40-45 minutes or until center is no longer jiggly. I place my pie plate on a cookie sheet when baking so that if it bubbles over it lands on the cookie sheet not my oven.
