Preheat your oven to 180 C (350 F) and grease glass pie dish with butter and set aside.
Heat a large non stick pan and brown the beef until no pink is visible. Break up the beef as it cooks with the spatula. Just starting with the beef here.
Add the taco seasoning and water and reduce heat, cook for a few minutes to reduce the liquid and makes a thick sauce.
Add the beef to the prepared pie dish and spread to make an even layer.
In a mixing bowl, add the eggs, cream, garlic, salt, and pepper, mix together then pour over the beef. (Yes, I was making two pies.)
Top with the cheese.
Bake for 30 minutes or until the egg is set and the cheese starting to brown. Let rest for 5 minutes before slicing.
Serve with toppings of sour cream, chopped tomatoes, chopped avocado, or toppings of your choice. Enjoy.
