Creamy Potato & Onion Bake with a Butter Crumble Crust

Share the joy

This is such an easy and deliciously scrumptious potato dish to make. It’s excellent served with a steak, sausages or any grilled/pan-fried meats. It can be prepared well in advance and reheated so is perfect for dinner parties.


Layers of sliced potatoes and onion rings.


Pour over the cream and top with cheese – I recommend ‘raclette’ cheese. Sea salt and ground pepper to garnish!

I highly recommend using a ‘raclette’ type cheese because, when heated, it melts and combines with the cream to make a thick, velvety and luscious sauce. I like to top my dish with a buttery and salty biscuit crumble – the combination of textures and flavours is just sensational. Give it a go – it’s so easy to make!

Creamy Potato & Onion Bake with Crumble Crust


  • 5 medium/large potatoes ( I allow one potato per person), sliced
  • 1 large onion, sliced into rings
  • 400ml pouring cream
  • 5 or 6 slices of ‘raclette’ cheese or similar
  • Ground sea salt and black pepper
  • 75/100g of soft butter
  • Just over half a pack of ‘tuc’ biscuits or similar


  1. Wash and slice the potatoes, skins on.
  2. Peel and thinly slice the onion
  3. Layer the potatoes and onions alternatively in a deep oven proof dish
  4. Add a sprinkle of salt and pepper each time and top up with cream.
  5. Add the slices of ‘raclette’ cheese and top with ground salt/pepper.
  6. Cover the dish with foil and bake in an oven (180/190 degrees or 350 degrees fahrenheit) for about an hour, or until the potatoes have softened.
  7. While the potatoes are in the oven, place the ‘tuc’ biscuits into a plastic food bag and crush to make crumbs.
  8. Place the biscuit crumbs in a bowl and combine with the soften butter.
  9. When the potato bake is cooked, remove the foil and sprinkle over the crumble mixture.
  10. Replace the potato with crumble top back in the oven for 10 mins or until browned and bubbling.
