I do not make quiche very often but when I do, this is the recipe I use. It is a great dish to make and this recipe makes a great base that you can modify to your own tastes. It is the perfect recipe to show off your creativity too.
I often throw in (or substitute in) many combinations including broccoli, cauliflower, cherry tomatoes, and mushrooms. If you are not a lover of onions, substitute some butternut squash and instead of half-and-half, use heavy whipping cream instead. The possibilities are almost endless.
9” deep dish pie crust (or make your own)
4 lg. eggs, beaten
1 ¼ c. shredded Swiss cheese (or other cheese, depending on your preference)
1 c. half-and-half
¾ c. Parmesan cheese
½ c. diced onion or 1 T. dehydrated onion (link)
¼-1/2 c. bacon bits
Preheat your oven to 400 degrees.
Place your pie crust onto a baking sheet. In a large bowl, stir together your cheeses, the bacon bits, and your onions together. Spread this mixture evenly over your pie crust. Now, using that same bowl, whisk together your eggs and half-and-half. Pour this mixture over the cheese mixture.
Bake for 15 minutes. Turn the heat down to 350 degrees and bake for about 12-14 more minutes or until the quiche beginning to brown and the top of the quiche is set and puffy.
