Servings: 8
Ingredients
- 1 cup grated sharp cheddar cheese or a mix of gruyere, parmesan, Swiss
- ½ cup self-raising flour or plain flour mixed with ¾ tsp baking powder
- 3½ ounces ham finely chopped
- 2 teaspoons wholegrain mustard Dijon or similar alternatives acceptable
- 5 ounces mushrooms finely diced
- 1 onion medium, thinly sliced into rings
- 1 tablespoon butter
- ¼ teaspoon freshly ground black pepper
- 4 large eggs gently beaten
- ¼ teaspoon salt
- 1½ cups milk
Instructions
- Preheat your oven to 375°F (190°C), or 390°F (200°C) for conventional ovens.
- In a large skillet, melt butter and sauté the sliced onions slowly for approximately 10 minutes until soft and lightly caramelized.
- Introduce the chopped mushrooms to the pan, cooking for an additional few minutes until tender.
- Lightly grease a 9.5-inch (24 cm) quiche dish or similar baking pan with butter or oil spray. Evenly spread the sautéed onion and mushroom mixture across the base. Distribute the chopped ham and cheese evenly on top.
- In a large jug, gradually whisk milk into the flour to create a smooth blend without lumps. Add the whisked eggs, mustard, salt, and pepper, combining thoroughly.
- Carefully pour the liquid mixture over the ingredients in the quiche dish.
- Bake in the preheated oven for 30–40 minutes, or until the center is fully set. Allow to rest briefly, then slice and serve warm.
