How to cook a frozen quiche?

A quiche is a classic French dish that has become a favourite of many around the world. It is a savoury pie made with eggs, milk, cream, cheese and other fillings such as veggies, meats or seafood baked in a pastry crust.

Frozen quiches are incredibly convenient because they offer quick and easy access to a delicious meal at any time. They can be stored in the freezer for several weeks and readily available when needed. In this article, we’ll explain how to cook a frozen quiche so you can enjoy this delightful treat without hassle.

Thawing the Quiche

Before cooking your frozen quiche, it’s important to thaw it properly first. This step ensures even cooking throughout your dish and ensures you avoid an undercooked centre or overcooked edges.

The recommended methods for thawing a frozen quiche include leaving it overnight in the refrigerator, using the defrost function on your microwave or leaving it out at room temperature.

Overnight Refrigerator Method

To thaw your frozen quiche using the overnight refrigerator method:

  1. Remove your frozen quiche from its packaging
  2. Place the frozen quiche on a plate
  3. Cover tightly in plastic wrap or aluminium foil
  4. Store in the refrigerator overnight

Microwave Defrost Method

To defrost your frozen quiche using your microwave:

  1. Place your frozen quiche into your microwave
  2. Use defrost mode for 3-4 minutes per slice (check manufacturer guidelines)
  3. Rotate halfway through to ensure even thawing
  4. Remove when soft but not fully cooked

Room Temperature Method

To defrost quickly at room temperature:

  1. Remove from its packaging
  2. Put it on top of paper towels
  3. Leave it under room temperature for approximately one hour until fully defrosted

It is crucial never to thaw Quiches at hot temperatures such as in hot water or under direct heat. Thawing using any of the methods mentioned may soften the quiche crust, but it will not affect the overall taste quality.

Preparing The Oven

Before heating your oven, you should ensure that you have adequately prepared it for baking your frozen quiche. Setting a precise temperature is key to getting the perfect baked quiche.

The recommended oven temperature and time are crucial for different types of quiches depending on size, ingredient type and thickness.

Here are some guidelines:

  • Mini Quiches: 350°F (177°C) for 15-20 minutes
  • Small-sized Quiches: 375°F (190°C) for 25 -30 minutes
  • Large Quiches: 400°F (204°C) for 40-50 minutes

Please note; these cooking times above assume that the quiche has been thawed correctly according to manufacturer instructions

Preparing The Baking Dish

Choosing an appropriate baking dish is also essential when cooking your frozen quiche. It would be best to get a pie dish that can withstand high temperatures from around 425℉ or has good thermal conduction abilities.

The ideal choice is a deep-dish pie plate or a tart pan with a removable bottom since they offer more space with their sides suitable for thicker fillings such as meats or vegetables without spilling over while baking. They also present the added advantage of easy removal after baking, ensuring neatness when serving.

Although glass bakeware looks elegant and allows viewing of food during preparation, they can crack sometimes due to thermal shock caused by sudden temperature changes when placing them directly in a heated oven. In contrast, ceramic dishes might take too long to absorb heat and cook contents evenly.

Baking The Quiche

Once your oven is hot, and baking tray lined with parchment paper then ready, you can start preparing the pre-cooked quiche for baking.

If you want to enhance the flavour of your quiche, then adding toppings or fillings would be an excellent option. Suggestions include bacon bits, shredded cheese, chopped veggies or cooked meats or seafood.

Here are some options for vegetarian or gluten-free recipes;

Vegetarian Quiches

  • Cheese and spinach
  • Mushroom and caramelized onions
  • Artichoke and tomato basil
  • Broccoli cheddar casserole

Gluten-Free Quiches

  • Potato crust quiche
  • Sweet potato crust quiche
  • Rice flour crust quiche
  • Cornmeal crust quiche

Once additional toppings have been added to the frozen quiche, gently pat them down so that they are distributed evenly across it. You can also add a small amount of cheese on top for extra melty goodness!

Place the filled baking dish in the oven and bake according to the recommended temperature based on its size. During baking, be careful not to overcook your quiche until it turns brown around the edges. An ideal indication that your quiche is fully cooked would be when there are no visible jiggles in layers when gently shaken.

Checking Doneness

It’s important to confirm that your frozen Quiche cooks correctly before serving it to guarantee health safety risks such as undercooked egg whites aren’t present.

Checking if your Quiche is thoroughly cooked is simple by applying one of two time-honoured methods:

Toothpick Test

To perform a toothpick test; insert a toothpick at least two inches into the centre of the dish and remove slowly. If there’s any uncooked batter sticking to it, then put back in for more cooking.

Knife Test

To perform a knife test; take a sharp kitchen knife tip into where little rawness remains and twist gently but firmly without breaking open too much or unevenly.

Serving Your Quiche

Once your quiche has reached doneness, it should be allowed to settle and cool down at room temperature for a few minutes before serving. This cooling process helps retain a perfect shape when cut into portions for serving.

If any leftovers are present, they should be wrapped tightly in plastic wrap and placed inside an air-tight container before storing them away. Leftover quiches usually last about two to three days in the refrigerator and can still be reheated perfectly well in the oven or microwave.


Cooking a frozen quiche is an excellent way to enjoy an easy meal without much hassle. By following these methods explained above, you are guaranteed to cook your favourite dish of completely thawed, evenly baked crust with melts-in-your-mouth filling every time. Enjoy!


  1. Q: Can I cook a frozen quiche without defrosting it first? A: Yes, you can! In fact, many frozen quiches are designed to be cooked straight from the freezer. Just make sure to adjust the cooking time and temperature accordingly, as the quiche will likely take longer to cook than if it were thawed.
  2. Q: How do I know when my frozen quiche is fully cooked? A: The best way to tell if your frozen quiche is fully cooked is by checking the internal temperature using a meat thermometer. Insert the thermometer into the center of the quiche; once it reaches 165 degrees Fahrenheit, your quiche should be safe to eat.
  3. Q: Should I preheat my oven before cooking a frozen quiche? A: Yes, definitely! Preheating your oven helps ensure that your quiche cooks evenly and thoroughly. Check the packaging for specific preheating instructions, but in general, you’ll want to preheat your oven to around 375 degrees Fahrenheit.
  4. Q: Are there any tips or tricks for getting a crispy crust on my frozen quiche? A: Absolutely! One trick is to brush a thin layer of beaten egg or milk over the crust before baking; this can help give it a nice golden-brown color and crispy texture. You could also try placing your frozen quiche on a baking sheet lined with parchment paper, which can help prevent any excess moisture from seeping into the crust and making it soggy.
