However, if you have never cooked quiche before, you might find it challenging to prepare. In this article, we will provide you with a step-by-step guide on how to cook costco quiche, so you can enjoy this mouth-watering dish from the comfort of your home.


Costco is a popular warehouse club that offers a wide range of products, including pre-made quiches. While these pre-made quiches are convenient, they can be expensive, and you might want to learn how to cook Costco quiche from scratch. Cooking your own quiche is not only cheaper, but it also allows you to customize it to your liking. In this article, we will guide you through the process of cooking a delicious and fluffy Costco quiche that is perfect for any occasion.

Ingredients Needed

Before you start cooking your Costco quiche, you need to gather all the necessary ingredients. Here are the ingredients you will need:

  • 1 and 1/4 cups of all-purpose flour
  • 1/2 teaspoon of salt
  • 1/2 cup of unsalted butter
  • 1/4 cup of ice-cold water
  • 6 large eggs
  • 1 and 1/2 cups of heavy cream
  • 1/2 teaspoon of salt
  • 1/4 teaspoon of black pepper
  • 2 cups of shredded cheese (you can use any cheese of your choice)
  • 1 cup of cooked and crumbled bacon (optional)
  • 1/2 cup of chopped onions (optional)

You can purchase all these ingredients from your local grocery store or Costco. Once you have all the ingredients, you can start preparing your Costco quiche.

Preparation of the Crust

The crust is an essential part of any quiche, and a perfect crust makes all the difference. Here’s how to prepare the crust:

  1. In a large bowl, mix the flour and salt together. Cut the butter into small cubes and add it to the flour mixture. Using a pastry cutter, cut the butter into the flour until it resembles coarse crumbs.
  2. Gradually add the ice-cold water, one tablespoon at a time, while mixing the dough with a fork. Keep adding water until the dough comes together and forms a ball.
  3. Wrap the dough in plastic wrap and refrigerate for at least 30 minutes.
  4. Preheat the oven to 375°F (190°C). Roll out the dough on a floured surface until it is about 1/4 inch thick. Transfer the dough to a 9-inch pie dish and trim the edges.
  5. Prick the bottom of the crust with a fork and bake for 10-12 minutes or until lightly golden brown. Remove from the oven and let it cool.

Preparation of the Filling

The filling is the heart of the quiche, and you can customize it to your liking. Here’s how to prepare the filling:

  1. Preheat the oven to 375°F (190°C).
  2. In a large mixing bowl, beat the eggs and heavy cream together until well combined. Add the salt and black pepper and whisk until fully incorporated.
  3. Add the shredded cheese, cooked bacon, and chopped onions (if using) to the egg mixture and stir until evenly distributed.
  4. Pour the mixture into the cooled pie crust and spread it evenly.
  5. Bake the quiche for 35-40 minutes or until the filling is set and the top is lightly golden brown. You can check if the quiche is fully cooked by inserting a toothpick in the center. If it comes out clean, the quiche is done.
  6. Remove from the oven and let it cool for 10-15 minutes before slicing and serving.

By following these simple steps, you can make a delicious and fluffy Costco quiche that is perfect for any occasion.

Baking the Quiche

Now that you have prepared your quiche filling and crust, it’s time to bake your Costco quiche. Follow these steps:

  1. Preheat your oven to 375°F.
  2. Place your prepared crust on a baking sheet.
  3. Pour the quiche filling into the crust. Make sure not to overfill the crust.
  4. Bake the quiche for 40-45 minutes or until the filling is set and the top is golden brown.
  5. Once the quiche is baked, remove it from the oven and let it cool for a few minutes.
  6. Slice the quiche into wedges and serve.

Serving and Storing

Your Costco quiche is now ready to be served. Here are some tips:

  • You can serve your quiche hot or cold, depending on your preference.
