How do I know when the quiche is done?

The Costco Quiche is done when the center is set, and the edges are golden brown.

You can test the center by lightly touching it with your finger. If it’s still jiggly, it needs to cook longer. The best way to check the edges is to use a knife or fork to lift a corner and peek underneath. 

If the edges are browned and crispy, the quiche is ready to come out of the oven.

Remember that the quiche will continue to cook for a few minutes after it’s removed from the oven, so you don’t want to overcook it.

When in doubt, err on caution and take the quiche out sooner rather than later. Better to have a slightly undercooked quiche than one that’s burnt!

Can I add or replace some ingredients?

Yes, you can add or replace ingredients in the quiche. If you want to change the fillings, some good options include bacon, sausage, mushrooms, onions, or peppers.

And, if you’re not a cheese fan, you could use Swiss, Gruyere, or even goat cheese instead.

Remember that changing the ingredients will also change the nutritional information.

Tips and tricks for a better recipe


First of all, get creative with your fillings! Try different meats, vegetables, and cheeses to suit your taste.

  • For a flakier crust, blind bake the crust for 10 minutes before adding the fillings.
  • Use high-quality ingredients for the best results.
  • To avoid a soggy crust, make sure the filling is not too wet. If using vegetables, cook them first to release some of their moisture.
  • Preheat the oven before baking the quiche to ensure even cooking.
  • Bake the quiche on a preheated baking sheet to prevent the bottom from overcooking.
  • Check the quiche early and often while baking so you can take it out at the perfect time.
  • Let the quiche cool slightly before slicing and serving to prevent it from falling apart.
  • Serve the quiche with a simple salad for a complete meal.
  • Store leftovers in the fridge and reheat them gently before serving.
  • This recipe can easily be doubled or tripled to feed a crowd.

And finally, to make individual quiches, use ramekins or mini pie dishes instead of a large pie dish.

Should I cook in the oven or in the microwave?

The microwave is the best way to cook a quiche if you’re short on time. Simply place the quiche on a microwave-safe plate and cook for 2-3 minutes, or until the center is cooked through.

Remember that microwaves vary in power, so you may need to experiment with cook times to find what works best for you.

If you have a little more time, cooking the quiche in the oven will give you the best results. The oven gives the quiche a chance to cook evenly and allows the crust to get nice and crispy.

Simply preheat the oven to 350 degrees Fahrenheit and bake the quiche for 40-45 minutes.

Can I cook in the Air Fryer?

Yes, you can cook the Costco quiche in an air fryer! Simply preheat your air fryer to 350 degrees Fahrenheit and cook the quiche for 10-12 minutes.

The result is a crispy, flakey crust and a perfectly cooked egg filling.

Plus, there’s no need to worry about mess or cleanup since the air fryer will do all the work for you. Keep an eye on the quiche while it’s cooking, as air fryers can vary in power, and you don’t want to overcook it.

Final Words

The quiche is a versatile dish that can be made ahead of time and easily reheated.

It’s also a great way to use leftover ingredients in the fridge. And, with so many different possible flavor combinations, there’s sure to be a quiche that everyone will enjoy. So, give quiche a try next time you’re looking for an easy and delicious meal!
