How to Make Onion & Cheese Quiche Recipe

Step 1: Preheat Your Oven

Start by setting your oven to 200 degrees Celsius. A properly preheated oven ensures that your crust will bake evenly and the filling sets up beautifully without becoming watery.

Step 2: Prepare the Pie Crust

Roll out your savoury shortcrust pastry and carefully line it into your quiche mould or pie tin. Don’t forget to prick the base gently with a fork; this helps to prevent bubbling or puffing during baking. Bake the crust for 15 minutes to give it a head start on getting crisp.

Step 3: Caramelize the Onions

Heat the oil in a frying pan and add the thinly sliced onions. Slow cooking them until they turn a rich golden brown brings out their natural sweetness, creating that deep flavor that’s crucial for this quiche. Once caramelized, set the onions aside to cool.

Step 4: Mix the Egg Custard Base

Whisk together the eggs, salt, pepper, and milk until fully combined. This mixture forms the silky custard that binds everything together while adding richness and tenderness to each slice of quiche.

Step 5: Combine Filling Ingredients

Fold the grated cheese and cooled caramelized onions into the egg mixture along with dried parsley. This blend promises a perfect balance of savory, sweet, and slightly herby flavors within the quiche.

Step 6: Assemble and Bake

Pour the filling carefully into your pre-baked pie shell. Place it back in the oven and bake for another 15 to 20 minutes until the filling is set with a slight wiggle in the center and the top turns a lovely golden color.

Step 7: Cool and Serve

Remove your onion and cheese quiche from the oven and allow it to cool for about 5 minutes. This resting period lets the custard settle for cleaner slicing and easier serving. Finally, unmould, slice, and enjoy!
