Ingredients

350g chilled gluten free shortcrust pastry dough
2 white onions, finely diced
100g Gruyère cheese, chopped into small cubes (Comté or cheddar also work)
120ml double cream
3 large eggs
40ml milk
black pepper, to taste

Directions

Preheat oven to 180°C (fan). Lightly grease a 24cm loose-bottom tart tin.
Cook the diced onions in a frying pan over low heat for 10 minutes until softened. Set aside.
Place cling film on the worktop and dust with gluten-free flour. Roll pastry dough between cling film and greaseproof paper until 0.5cm thick and large enough to cover the tart tin.
Carefully lift pastry into the tin, pressing into the base and sides. Trim any excess with a sharp knife.
Prick the base with a fork, then cover with greaseproof paper and baking beads. Blind bake for 10 minutes at 180°C.
Remove paper and beads, then bake the tart case for another 10 minutes at 160°C. If the base looks raw, bake for 5 minutes longer.
Meanwhile, whisk together eggs, cream, and milk in a bowl. Season with black pepper, then stir in the cooked onions.
Place cheese cubes evenly on the pastry base. Pour in the egg mixture.
Return quiche to the oven and bake until set and golden, about 25–30 minutes.
Cool slightly before slicing and serving.

FAQs

Can I make this quiche ahead of time?

Yes, bake the quiche completely, then refrigerate. Reheat before serving.

Can I use store-bought gluten free pastry?

Absolutely. Store-bought pastry dough works perfectly for convenience.

How do I prevent a soggy quiche bottom?

Blind baking the pastry case ensures the base cooks through before adding filling.

Can I substitute the cream with milk?

You can, but the filling will be lighter and less rich. A mix of cream and milk works best.

What cheese works best if I don’t have Gruyère?

Comté, cheddar, or Swiss cheese make excellent substitutes.

Can I add vegetables to the filling?

Yes, spinach, broccoli, or sautéed mushrooms are great additions.

How do I know when the quiche is done?

The filling should be set in the center but still slightly wobbly. It will firm as it cools.

Can I freeze quiche?

Yes, freeze baked quiche whole or in slices for up to 2 months. Reheat in the oven.

Is this quiche suitable for lactose-intolerant diets?

It can be made lactose-free by using dairy-free cream, milk, and cheese alternatives.
