This gourmet quiche features brown butter, flour, eggs, heavy cream, mixed alliums (onions, shallots, leeks), whole garlic cloves, Gruyère and Parmesan cheeses, fresh thyme, and olive oil. The distinct layers create a perfect balance of nutty, sweet and savoury flavours.
Learn how to cook Confit Garlic and Caramelized Allium Quiche by first making brown butter crust, preparing confit garlic in olive oil, caramelizing alliums slowly, and creating a silky custard filling. After blind baking the pastry, layer cheese, alliums and garlic before adding the custard mixture and baking until just set with a slight wobble in the centre.
Brown butter crust delivers a distinctly nutty, caramelised flavour that elevates the entire quiche. The process of browning the butter creates complex flavour compounds as milk solids caramelise, resulting in a more fragrant, richer pastry that shatters beautifully when sliced.
Thoroughly blind bake your pastry until it's dry and lightly golden before adding fillings. Using a proper ratio of eggs to dairy prevents excess moisture, while cooling caramelized onions and confit garlic completely removes excess liquid. A hot oven and proper resting time also ensure a crisp base.
Absolutely! Confit garlic can be prepared up to two weeks ahead and stored in its oil in the refrigerator. The tender, sweet cloves make excellent additions to mashed potatoes, pasta sauces, or spread on crostini. The infused oil is also delicious for dressings and drizzling.
