So let's start from the bottom up, because if you don't have a good crust you don't have a good quiche. I make my crust from scratch, and the recipe and method are super easy. In a medium bowl, mix 1 1/4 cups of AP flour and 1/4 tsp salt and stir to combine. Into this add one stick of cold butter, cut into very small chunks. Mix this together, making sure to incorporate all of the butter into the flour. At this point the dough should not be moist, and you should not see any chunks of butter. Slowly add cold water to the bowl, about 1 tbsp at a time. Be very careful not to add too much water - you only need enough to get the dough to come together into a ball, not to become wet and loose. Wrap the ball of dough in plastic wrap and chill in the fridge for at least 4 hours, though overnight is best. Roll out on a floured surface when ready to use - this will make one 9" pie crust with enough to have some leftover scraps.
Now let's move onto the quiche. For the filling, you will mix together 1/2 cup of milk and 1/2 cup of mayonnaise in a bowl, whisk together until it is smooth. Into this beat 4 large eggs until the mixture, and this is the custard base for your filling. Now, for any vegetation or anything else, you want to keep yourself to about 2 1/2 cups total, except for cheese. The cheese will melt in, so it won't take up a lot of volume, but with anything else you want to limit the size. I use about 8-10 ounces of cheese, generally cheddar. Pretty much anything can go in. Mushrooms, zucchini, peppers, ham, onion, spinach, and a lot of other things can go in. I made a classic recipe referred to as quiche Lorraine. This is a reference to a classic recipe that comes from the Lorraine region of France that was traditionally made with a salt-cured pork. Modern quiche lorraine uses bacon instead of the pork, and more often than not also includes wilted spinach. For this part of the meal, I cut up the bacon (about 6-7 slices) into strips and cooked them in a pan, then once they were cooked up I removed the bacon with a slotted spoon and then added in the spinach to wilt it in the bacon fat.
Once everything is assembled in the pie plate cover it with foil and pop it in a 400 degree oven on a cookie tray for about 40-45 minutes. Remove the foil and bake for another 10-15 minutes until the top is browned and the custard is set. Let the quiche cool and continue to set for about 10 minutes, then cut and serve.
