This Crustless Quiche feels like a cheese topped mega treat, but served with salad (or new potatoes for dinner), it still makes a really light and fresh meal.

It’s packed with protein and veggies too, all of the good stuff in one place.

A no-pastry vegetarian quiche recipe is such a good basic go-to meal as you can vary the fillings to fit with any veggies you have in the fridge or freezer, as well as surplus eggs, so it’s a great way of avoiding wasting food.

I’ve used broccoli and peas in this dish because they go so well with the eggs and cheese, but you can really choose whatever you prefer (see below for some more filling ideas).

How we came up with this recipe

I wanted to adapt my lunchbox Mini Crustless Quiches recipe so we could enjoy it as a full meal, albeit with sliceable leftovers for packed lunches if needed.

I realised just how easy, healthy and delicious a crustless quiche could be, and that it serves as so many different types of meal (brunch, lunch, dinner, picnic, buffet dish…)

Not only that, it’s also a fantastic way of using up surplus food, making it super budget friendly.

I tested this plenty of times to get the flavours and consistency just right and effort low, making sure we could simply add some cooked vegetables into the dish, pour the egg mixture over the top and leave on its own to bake.

I hope you love it!

Crustless Quiche Ingredients Notes

  • Broccoli – We’re going to chop this into bite-sized florets. Make sure you do the same with any other veggies to add
  • Onion – You can either chop a fresh onion up or use the equivalent quantity in frozen, pre-chopped onion for speed
  • Eggs – I always use medium, free range in my recipes so bear this in mind when thinking about quantities
  • Cheese – Try and use something that has plenty of flavour, like cheddar, but you can go with your favourite. This should be grated for even distribution

How to make Crustless Quiche

  1. Soften the onions in oil in a frying pan, then add the broccoli for 4-5 minutes, followed by the peas for a further 3 minutes.
  2. Once softened, add the veggies into a shallow dish.
  3. Beat the eggs and pour over the vegetables. Sprinkle cheese over and season.
  4. Bake for 25-30 minutes in a preheated oven at 180C. Leave to cool for 5 minutes before slicing.

Hint: The cooked quiche should be cooked through but still a little wobbly.

Other filling options

You can get really experimental here and avoid being too precious.

  • This recipe is a win for using up whatever you have left over, so just go for it! I love anything with onions.
  • Peas, mint and feta cheese go really well together, as does spinach and feta (which is more like a crustless Spanakopita quiche).
  • You can also add in meat if you like.

Leftovers

In the fridge You can keep this recipe in the fridge for 3 days. Reheat fully before serving or enjoy it cold.

In the freezer This recipe freezes well. Just wait until it’s totally cold, wrap it up well and then put into a freezer proof container and freeze for up to 3 months. Defrost thoroughly before reheating in the microwave or eat it cold.

Top tipS

Dish

You’ll need quite a shallow dish for this. Make sure it’s not too big or your quiche will be flat. I like this 25cm Pyrex pie dish from Amazon.

Leave to cool

It’s best to leave the quiche to cool for 5 mins before cutting it as it will be much easier to slice.

Make ahead of time

Cold Crustless Quiche makes a brilliant packed lunch dish. Just allow it to cool fully, wrap it well and then store in the fridge for up to 3 days.

FAQs

Is there a difference between a Crustless Quiche and a Frittata?

They can often have very similar ingredients, but traditionally a frittata would be cooked in a frying pan on the hob and finished under the grill, whereas a quiche is cooked in the oven.

Try my Smoked Salmon and Broccoli Frittata!

Is this a healthy quiche recipe?

Traditional quiches have a pastry base, which is packed with fats, and often the fillings are laden with heavy or double cream, which also adds to the calorie count.

Seeing as a Crustless Quiche omits the pastry and cream, plus has loads of vegetables, this is a lighter alternative.

Can I make a Crustless Quiche with meat?

Yes, you can add in meat if you don’t mind the quiche not being vegetarian. How about bacon and mushroom? Or pea and ham? You can also mix up the type of cheese you use too.

Do you have any more brunch ideas?

I do! Try out my Healthy Breakfast Muffins, my Shakshuka, simple Slow Cooker Salmon or my Creamy Salmon Bake.

How about other easy vegetarian meals?

I have lots! Try my 15 minute Halloumi Burger recipe, my super simple Chickpea Curry or one pan Tomato Pasta.

Is this a gluten free recipe?

Yes, this is a gluten free quiche recipe.

    Sarah I know you’re a gal who loves her cheese and loves her pesto, so I jazzed this up with you in my heart. I added pesto to the veges as they were frying; and I put extra cheese on top. It gave it more bite and it was DELICIOUS.
