MethodPreheat oven to 180°C (160°C fan-forced) and grease a large baking dish (approximately 30cm x 20cm). Cook the bacon in a large frying pan over medium-high heat until golden and crisp, about 5 minutes. Add the onion to the same pan and cook for 4–5 minutes until softened, then add the garlic and cook for a further minute. Arrange half the sliced potatoes in an even layer in the prepared baking dish. Cover the dish tightly with foil and bake for 40 minutes.
