Preheat the oven to 425 F / 220 C.
Make your pie crust (if making from scratch) and then place it in a pie pan. Poke your dough with a fork.
Blind-bake your pie crust at 425 F, it takes around 10-15 minutes to get the desired golden-brown edges.
In a bowl, combine the eggs, sour cream, milk, and seasonings (salt, black pepper, garlic powder, and onion powder) and mix well.
Dice the tomato.
Mince the fresh basil and the fresh parsley.
Add the diced tomato, cheddar cheese, fresh basil, and fresh parsley and mix until thoroughly combined.
Slice the zucchini. Make sure your slices aren’t too thick!
Reduce the oven’s temperature to 375 F / 190 C.
In your pie pan with the prebaked crust, add ½ of your quiche mixture.
Top with ½ of your sliced zucchini.
Add the remaining ½ of your quiche mixture and top with the remaining ½ of your sliced zucchini.
Bake at 375 F / 190 C for 40 minutes.
Enjoy!
