There’s nothing quite as versatile as a good impossible quiche.  You can eat it at any time of the day, by itself or with some easy sides.  

It stores well in the fridge for a few days and can be frozen for later if you can’t eat it all that quickly.  I’ve purposely kept this crustless quiche bare bones – just ham and cheese.  You can, of course, add in some veggies or mix it up with some bacon.

Or just leave it as is because it tastes absolutely delicious.  This recipe is a great way to use up leftover ham after the holidays, or just when you need an easy dinner you can throw together quickly.

Why you’ll love this recipe…

  • Very easy to prepare.

What is impossible quiche?

Impossible quiche, also known as a crustless quiche, is a quiche that requires no pastry base.  The reason it doesn’t require a base is that a little flour is added to the mixture before baking that separates and sinks to the bottom to form a light crust like magic!  

IMPOSSIBLE QUICHE INGREDIENTS LIST

This is such a good dinner to make in a pinch as it’s made from everyday ingredients most of us always have on hand!  Here’s what you’ll need to whip up this impossible quiche (full measurements listed below)…

  • Olive Oil 
  • Brown Onion 
  • Shredded Cheddar Cheese
  • Parmesan Cheese
  • Ham
  • Self-Raising Flour – If you don’t have self-raising flour simply use a mixture of plain / all purpose flour and baking powder. The conversion is 1 cup of flour to 2 teaspoons of baking powder. 
  • Milk
  • Eggs

HOW TO MAKE IMPOSSIBLE QUICHE – STEP BY STEP

Preheat the oven to 200C / 390F and grease a pie tray (9″ x 2″ / 22.5cm x 3.1cm).

Heat oil in a small frying pan and cook the onion until translucent. 

Combine 1 cup shredded cheddar cheese, parmesan cheese, ham, onion, flour, salt and pepper in a bowl, then pour into a pie dish.

Can you make crustless ham and cheese quiche ahead of time and reheat? 

Definitely.  Quiche is one of those foods that tastes just as good reheated the next day.  I personally prefer to reheat it in the oven but you can also zap it in the microwave too.  

Quiche can be stored in an airtight container in fridge for up to 3 days.  

Can you freeze quiche?

Absolutely.  Quiche freezes really well.  Just place it in an airtight container and store in the freezer for up to two months.  

What goes with quiche?

You can totally serve quiche on it’s own for an easy breakfast or light dinner.  I like to pair it with a simple salad and even some potatoes, especially if I’m feeding a few people.  Here’s a few recipes that go well with this quiche: 

  • Cabbage and Crunchy Noodle Salad
  • Greek Lemon Potatoes
  • Middle Eastern Bean Salad
  • Crispy Baked Potato Wedges
  • Pumpkin, Spinach & Feta Salad

Tips for Making Impossible Quiche

  • You can simply add the onion into the mixture without frying it first but I always find frying onion brings out more flavour and it’s worth the extra washing up! 
  • Feel free to add in some veggies to the quiche – some finely diced capsicum / bell peppers or a grated zucchini would go great!  
  • You can also try this quiche with bacon instead of ham.  Just fry the onion and bacon together first before adding to the rest of the ingredients.  
  • Great served warm or cold.
