Instructions

Preheat the oven

Preheat your oven to 190°C (375°F).

Caramelize onions

In a large skillet over medium heat, warm the olive oil and add the onions. Cook, stirring occasionally, until golden brown and caramelized, about 20 minutes.

Pro tip: Add a pinch of sugar to speed up caramelization.

Cook mushrooms

Add the sliced mushrooms to the skillet with the onions and cook until softened, about 5 minutes.

Wilt the spinach

Add the spinach to the skillet and cook until just wilted, about 2 minutes. Remove from heat and set aside.

Pro tip: Ensure excess moisture is drained from the spinach.

Prepare the custard

In a large bowl, whisk together the eggs, milk, heavy cream, salt, and pepper until well combined.

Assemble the quiche

Spread the onion, mushroom, and spinach mixture evenly over the pre-baked pie crust. Pour the custard mixture over the top and sprinkle with Gruyère cheese.

Bake the quiche

Place the quiche in the oven and bake for 30-35 minutes, or until the filling is set and the top is golden brown.

Pro tip: Check for doneness by inserting a knife into the centre; it should come out clean.

Cool and serve

Allow the quiche to cool for at least 10 minutes before slicing and serving.

Serve this quiche warm or at room temperature, perhaps with a fresh side salad for a complete meal. It pairs well with a crisp white wine or a light-bodied red. This quiche can be made ahead of time and stored in the refrigerator for up to three days. To reheat, simply pop it in a preheated oven at 180°C (350°F) until warmed through, about 10-15 minutes.
