The Very Best Crustless Quiche (Impossible Quiche!)
Description
The Very Best Crustless Quiche (Impossible Quiche!) brings together sautéed onions and mushrooms layered with ham and sharp cheese, all held together by a mixture of eggs, milk, and self-raising flour. The onions are cooked slowly until soft and caramelized, adding sweetness that balances the savory components. The mushrooms and ham contribute additional texture and flavor, while the cheese adds richness and a slight tang if using sharper varieties like cheddar or gruyere. The flour combined with eggs and milk creates a custard-like filling that sets during baking, producing a sliceable quiche without a traditional crust.
Baked at around 375°F until just set, this quiche showcases a lightly golden surface and a soft, tender interior. It can be served warm or at room temperature, making it adaptable for different meals. The recipe suggests pairing it with fresh salads or simple sides like baked potatoes for a complete lunch or light dinner.
Variations include swapping ham for bacon or mixing in cooked vegetables such as roasted asparagus or spinach. For a quicker version, raw finely chopped vegetables can be used, which may enhance the crustlike bottom formed during baking. This quiche also freezes well and can be reheated gently in an oven or air fryer, sometimes improving its texture and flavor after storage.
Ingredients
- 1 onion medium sized, any kind, sliced thinly into rounds
- 1 tablespoon butter for cooking the onions
- 5 ounces mushrooms around 4 medium mushrooms, best chopped into small pieces
- 3½ ounces ham chopped
- 1 cup cheese sharp (strong/tasty) cheddar is fine, or try gruyere, parmesan, Swiss cheese or a mixture of cheeses, grated
- ½ cup self-raising flour /self-rising flour (Alternatively, mix ¾ of a teaspoon baking powder into all-purpose/plain flour. Or you can use Bisquick.)
- 1½ cups milk
- 4 large egg lightly whisked (if you only have small eggs, add an extra one
- 2 teaspoons mustard (I usually use wholegrain, but Dijon or any other mustard also works)
- ¼ teaspoon salt or to taste
- ¼ teaspoon black pepper or to taste
Instructions
- Preheat the oven to 375°F (190°C) (increase to 390F/200C if you have a regular oven i.e. not a fan oven).
- Melt the butter in a large frying pan or saucepan. Then cook the onions slowly for about 10 minutes or until soft and beginning to caramelize.
- Add the mushrooms to the onions in the pan and cook for a further couple of minutes.
- Grease a standard quiche dish (around 9.5 inches/24 cm or similar - see note below) with a little butter, or spray with oil. Spread the onions and mushrooms evenly over the dish. Then scatter over the chopped ham and cheese.
- Slowly add the milk to the flour in a large jug. Whisk continuously so that there are no lumps, then whisk in the eggs, mustard, and salt and pepper.
- Pour the egg mixture evenly over the fillings in the dish. Then bake for 30 (to 40) minutes, or until the mixture is just cooked in the centre. Slice and serve!
Notes
- Use a quiche dish approximately 9.5 inches (24cm) in diameter or an equivalent-sized square or rectangular pan.
- Bacon can substitute ham; cook it first before adding the onions.
- Vegetables like leftover roasted veggies, asparagus, or blanched spinach can be added for variation.
- To speed up the recipe, use raw finely chopped vegetables such as onions and peppers with cheese directly, omitting pre-cooking.
- Letting the assembled quiche rest before baking may help the flour settle, enhancing the bottom crust.
- The quiche freezes well; reheat at 320°F (160°C) for about 20 minutes or in an air fryer for 6 minutes at the same temperature.
- Serve with fresh green or Greek salads, baked potatoes, coleslaw, or other easy sides for a full meal.
