Vegetarian Quiche with Spinach and Mushrooms

There’s something wonderfully comforting about a homemade quiche fresh from the oven. This Vegetarian Quiche with Spinach and Mushrooms combines a buttery homemade crust with a rich, cheesy filling packed with mushrooms, spinach, sweet pepper, and plenty of flavour. It’s the kind of dish that feels equally at home at a relaxed weekend brunch, a light family dinner, or even served cold for lunch the next day.

The combination of cheddar and mozzarella gives the filling a creamy texture while the mushrooms and spinach add heartiness without making the dish feel heavy. Making your own pastry may sound intimidating, but this crust is simple and forgiving, and the results are well worth the effort. Once baked, the golden crust and fluffy filling make this quiche look just as impressive as it tastes.

This recipe is ideal for feeding a family because it can easily be served with a fresh salad, roasted vegetables, or warm soup for a complete meal. It also reheats beautifully, making leftovers a real treat rather than an afterthought.

Serves 4–6

Ingredients

Crust

• 1½ cups cake flour
• A pinch of salt
• 6 tablespoons butter
• Ice water

The homemade crust gives this quiche its classic texture and buttery flavour. Resting the dough in the refrigerator helps create a tender crust that holds together beautifully once baked.

Filling

• 1 tablespoon butter
• 1 small onion, finely chopped
• 1 × 250 g mushrooms, sliced
• 1 cup fresh spinach, chopped
• 1 small red sweet pepper, seeds removed and cut into strips
• ½ cup cheddar cheese, grated
• ½ cup mozzarella cheese, grated
• Salt and freshly ground black pepper
• 4 eggs
• 1 cup milk
• A pinch of cayenne pepper

Instructions

1. Sift the flour and salt together. Rub the butter into the flour with your fingertips until it resembles coarse breadcrumbs.
2. Add small amounts of ice water and mix until you have a soft, workable dough.
3. Cover with plastic wrap and let it rest for 30 minutes in the refrigerator.
4. Roll the dough out on a floured surface and line a greased tart or quiche dish with it.

5. Place baking paper over the crust and fill with ceramic baking beans, regular dried beans, or rice.
6. Bake in a preheated oven at 200°C (392°F) for 10 minutes.
7. Remove the baking paper and beans, then bake uncovered for another 5–7 minutes.
8. Set the crust aside.

9. Melt the butter in a pan over medium heat. Add the onion and mushrooms and fry until the onion is soft and translucent and the mushrooms start to soften. Remove from the heat.
10. Stir in the sweet pepper, spinach, and both cheeses. Season with salt and pepper. Spoon the mixture into the prepared crust.
11. Whisk the milk, eggs, and cayenne pepper together and pour the mixture over the filling.
12. Bake for 40–45 minutes in a preheated oven at 180°C (356°F).

Tips

• If your dough feels too dry while mixing, add the ice water one teaspoon at a time to avoid making it sticky.
• Blind baking the crust helps prevent a soggy bottom once the filling is added.
• You can substitute the spinach with kale or Swiss chard if you prefer a slightly different flavour.
• For extra richness, add a little cream together with the milk in the egg mixture.
• Allow the quiche to cool for a few minutes before slicing so the filling can firm up properly.
• This quiche tastes great warm or cold, making it perfect for meal prep or packed lunches.

Serving Suggestions

Serve this Vegetarian Quiche with Spinach and Mushrooms warm with a crisp green salad, roasted baby potatoes, or a bowl of tomato soup for a comforting meal. A sprinkle of fresh herbs such as parsley or chives adds freshness and colour just before serving. If you are serving it for brunch, pair it with fresh fruit and coffee for a relaxed weekend spread.

The creamy filling and flaky crust also pair wonderfully with lightly dressed rocket salad or grilled vegetables. Leftover slices can be enjoyed cold straight from the refrigerator, making this recipe practical as well as delicious.
