Recipe Information
Ingredients
- 900 g Potatoes
- 500 g Onions
- 150 g Butter
- 1 tsp Salt
- 0.5 tsp Black Pepper
Instructions
Preheat your oven to 180°C (350°F) and grease a medium-sized ovenproof dish with a small amount of butter.
Peel the potatoes and slice them thinly into rounds, about 1-2 mm thick. Use a mandolin slicer if available for even slices.
Peel and finely slice the onions into thin half-moons.
In a large frying pan over medium heat, melt half of the butter (75g) and add the onions. Cook them gently for about 10-12 minutes, stirring occasionally, until they are soft and lightly golden.
Season the sliced potatoes with salt and black pepper, tossing them gently to evenly coat.
Start layering the dish: Place a layer of potato slices at the bottom of the greased dish, slightly overlapping them. Add a layer of the cooked onions next. Repeat the layers, finishing with a top layer of potatoes.
Melt the remaining butter (75g) and pour it evenly over the top layer of potatoes.
Cover the dish with foil and bake in the preheated oven for 45 minutes.
Remove the foil and bake for an additional 20-30 minutes, or until the top layer of potatoes is golden brown and crispy, and the potatoes are tender when pierced with a fork.
Let the Welsh Onion Cake cool for 5 minutes before serving. Slice into portions and enjoy warm as a side dish or as a meal on its own.
