    Crustless vegetable quiche

    This crustless vegetable quiche can be made with a combination of any vegetables of your choice. It's a fantastic recipe to have in your repertoire because you can vary it depending on whatever vegetables you happen to have available at the time. It's a great recipe to have on hand when you are clearing out your refrigerator.

    You can literally use any mixture of vegetables that takes your fancy. Why not try adding butternut, or use a couple of cups of broccoli and cauliflower florets for a new take on cauliflower cheese?  Or substitute the onions with leeks? Anything goes - this is a great way of using up any veggies you might have lurking in your fridge.

    I find that if you par-cook the vegetables first it gives them a head-start when they get into the oven. That way you can be sure that you don't get a mixture of soggy and under-cooked vegetables.

    The custard is made with a mixture of egg, cream and milk, which is mixed with a little flour. As the quiche bakes, the custard firms up and holds the quiche together, so there is no need for any pastry.

    What I like about this recipe is that it is packed so full of vegetables that one slice is sufficient as an accompaniment to a roast, meaning you don't have to cook lots of different veggie dishes. It is also really good served cold as an alternative to a salad with a barbeque. 

    You could even eat a slice by itself as a quick and easy lunch with a bowl of Orzo pasta summer salad. A slice of this crustless vegetable quiche would make a fantastic accompaniment to some air-fryer chicken drumsticks or parmesan-crusted pork chops.

    What you will need

    Equipment

    To make this crustless vegetable quiche you will need a sharp knife and a chopping board for cutting up the vegetables, and a cheese grater for grating some of them. You will also need a large frying pan and a 10" x 7" baking dish (approximately).

    Ingredients

    This recipe will easily feed 6 to 8 people as a side dish. Leftovers can be stored covered in the refrigerator for up to 3 days and enjoyed either cold as a light lunch, or warmed up and served as a side dish.

    **You can get the complete list of ingredients and full instructions for making this crustless vegetable quiche on the printable recipe card at the end of this post**

    Ingredients for a crustless vegetable quiche.

    These are the ingredients you will need for making the crustless vegetable quiche. It looks a lot, but most of them are vegetables. The custard itself is made with only milk, eggs, cream and flour.

    The total weight of all the vegetables is 750 grams (or one pound and 10 ounces). You can mix and match whatever vegetables you have handy. If you have more or less than this amount, you should adjust the volume of the custard accordingly. These are the vegetables I used:

    Onion - chopped into approximately half-inch pieces.

    Potato - grated on the largest holes of your grater.

    Zucchini (baby marrow/courgette) - sliced into thin rings.

    Carrot - grated on the largest holes of your grater. If you prefer larger pieces of carrots,

    Green beans - chopped into 2-inch pieces.

    Mushrooms - thinly sliced. You can your mushrooms of choice - I used white closed-cap mushrooms, but chestnuts, button mushrooms or even large portobello (or flat) mushrooms are fine.

    Cream - I used double (or heavy) cream - single cream is fine too.

    Eggs - lightly beaten into the cream.

    Milk - to add to the eggs and cream to make up 1 and a half cups.

    Flour - mixed with the eggs, milk and cream.

    Olive Oil - for frying the vegetables.

    Grated Cheese - to sprinkle on top of the quiche before it is baked.

    Salt and freshly ground black pepper - to taste. I find that a small quantity of salt both in the vegetables (as they are frying) and in the custard (before it is poured over the vegetables) gives the best results. This dish also loves black pepper, so be generous.

    What to do

    Prepare the vegetables

    • Chop the onion into fine dice and grate the potato and carrots. We don't want chunky pieces of potato in this dish.
    • Slice the zucchini into thin rings
    • Grate the carrot
    • Chop the green beans into 2-inch pieces
    • Slice the mushrooms or cut them into halves or quarters depending on their size

    Prepare the milk mixture

    • Measure the cream into a measuring jug.
    • Break the eggs into the cream and whisk lightly to combine.
    • Pour milk into the eggs and cream mixture until you have one and a half cups of liquid in the measuring jug.
    • Add the flour to the milk mixture and beat well to ensure there are no lumps of flour floating around.
    • Season with salt and pepper

    Pre-cook the vegetables

    This step gives the vegetables a head start and ensures they will be fully cooked once the quiche has been cooked in the oven.

    Heat the oil in a large frying pan or saucepan. Add the onions and potatoes, season with salt and pepper, and saute on a low heat for 3 to 4 minutes until the onion starts to turn translucent.

    Add the grated carrots and chopped beans and stir-fry for 2 minutes longer until the beans turn bright green.

    Mushrooms and courgettes added to the other vegetables in a frying pan.

    Now add the zucchini and mushrooms and stir-fry for 2 minutes longer. Allow to cool.

    Transfer the cooled vegetables to a baking dish, pour over the custard and sprinkle the grated cheese on top.

    Bake

    Place the quiche in a preheated oven - 200C / 400F - for approximately 30 minutes until the cheese has melted and the egg and milk mixture has set.

    This quiche sets firmly once cold, making it easy to cut a slice and eat in your fingers for a snack on the go.

    Crustless vegetable quiche FAQ

    Can I freeze this quiche?

    I wouldn't freeze this dish because the vegetables would become soggy and the egg and cream mixture would split when it defrosts.  This dish is best eaten fresh, and it will keep quite happily in the fridge for up to 3 days.

    Can you give me some ideas for variations?

    Sure - most vegetables will be suitable. Cauliflower and broccoli florets, butternut squash, broad beans. Why not use a mixture of grated white potatoes and grated sweet potatoes (yams)? Add some frozen peas or corn. Swap out the onions for leeks. Add some cubed butternut. The choice is endless.
    Some points to bear in mind when swapping out the vegetables:
    - have approximately 750 grams (1 pound 10 ounces) of vegetables for the amount of custard in the recipe.
    - don't precook any frozen vegetables you may decide to use or they will turn mushy. And make sure they are defrosted before you mix them in.
