Cooking Instructions For Frozen Costco Mini Quiches

Homemade Mini Quiches
  1. Preheat your oven to 375°F.
  2. Remove the quiches from their packaging and place them on a baking sheet. Make sure to leave enough space between each quiche [1] to heat up evenly.
  3. Bake the quiches in the oven for 20-25 minutes or until thoroughly heated and golden brown on top.
  4. Once the quiches are fully cooked, remove them from the oven and let them cool for a few minutes before serving.


Can You Cook Them In The Microwave?

While it’s not recommended, you can cook Costco Mini Quiches in the microwave if you’re short on time. To do so, transfer the frozen quiches to a microwave-safe dish and heat them on high for 30-40 seconds per quiche. 

However, microwaving the quiches can result in a soggy and unappetizing texture, so it’s best to cook them in the oven for a crispy and golden crust. 

“Shoot for a total of no more than 80 grams of carbs in your daily diet. This means favoring vegetables that grow above ground like kale, broccoli, spinach, and cauliflower as opposed to those that store carbohydrate in the form of starch like potatoes and beets.”

– David Perlmutter, American Doctor

If you must use the microwave, check the internal temperature of the quiches to ensure that they are fully cooked before serving. 

Microwave cooking times may vary depending on the number of quiches and the power of your microwave, so it’s best to keep a close eye on the quiches to avoid overcooking them.

How Do You Know When Mini Quiches Are Fully Cooked?

To know when Costco Mini Quiches are fully cooked, it’s best to check the internal temperature of the quiches. The quiches should reach an internal temperature of 165°F before they are safe to eat. 

You can use a meat thermometer to check the temperature of the quiches in the center. Insert the thermometer into the center of one of the quiches, being careful not to touch the baking sheet or the sides of the quiche. 

If the internal temperature reaches 165°F, the quiches are fully cooked and ready to be served. If the temperature is below 165°F, return the quiches to the oven and continue baking until the desired temperature is reached. 

By checking the internal temperature, you can ensure that your mini quiches are safe and fully cooked without overcooking them and compromising their taste and texture.
