While the crust is blind baking; using a hand mixer or electric mixer, whisk together the eggs, milk, heavy cream, salt, pepper, garlic powder and paprika until all ingredients are combined and fluffy
Once the crust is out of the oven, fill the bottom of the crust with the broccoli florets and the shredded white cheddar cheese (add any other ingredient add ins at this point)
Pour the quiche filling over the top of the broccoli and cheese
Reduce the oven temperature to 350 degrees F and bake the quiche for 35-40 minutes or until the center is set
Allow the quiche to cool for 10 minutes before cutting and serving
If you have leftovers, wrap the quiche in plastic wrap and store in the refrigerator for 3-4 days
